Xu Fan silently observed the stone wall. He was sure that with Zhu Zhengbiao's life in his hands, he would not dare lie to them, but he had observed it with his naked eyes for a long time, and had not discovered anything strange about it.

"What's going on? Logically speaking, this brat couldn't have lied to us. Did I miss something? That's right, how did I forget about my consciousness? "

Xu Fan thought to himself. After thinking about it for a bit, he suddenly remembered his powerful spiritual sense.

With a thought, Xu Fan immediately sent out his divine sense and examined the stone wall again.

Sure enough, through his powerful spiritual sense, Xu Fan quickly became aware of a faint shadow of a cave behind the stone wall.

"As expected!"

Xu Fan was overjoyed. He quickly used his divine sense to scan the surrounding walls. Soon, he found a protruding rock about ten feet away from the wall. This rock was very smooth, and it seemed to have been moved quite a bit.

Xu Fan walked over to the rock, reached out, and grabbed the rock. Lifting it slightly, he realized that he couldn't lift it. Afterwards, he tried to turn left and right.

In the next moment, the stone wall in front of him suddenly moved several zhang in height. Soon after, a huge stone cave appeared in front of him.

"Ah, immortal master, this lowly one has never lied to you, right?"

Seeing Xu Fan open the cave, Zhu Zhengbiao was immediately overjoyed as he hurriedly said in a flattering manner.

Xu Fan smiled and said, "That's right. With you leading the way, it'll save me a lot of trouble, but …"

After saying that, he gave Liu Da Feng a meaningful glance.

When Zhu Zhengbiao heard this, he was overjoyed. He thought that he could finally keep his little life, but he suddenly felt a pain in his chest. He looked down and saw a bloody spear sticking out of his chest.

"Immortal Master, you …"

Zhu Zhengbiao looked at his chest in fear, then he tilted his head as he realized that his soul had returned to the underworld.

Xu Fan released a fireball and turned Zhu Zhengbiao's corpse into ashes. After he was done, he said, "Big Sister Feng, you wait outside. Wait for me to go in and take a look."

Liu Da Feng naturally didn't have any objections. He held his spear to guard the entrance of the cave, and Xu Fan carefully walked into the cave.

When he walked into the cave, he realized that it was just a false alarm, but there was another cave in the cave.

At the end of the tunnel was a large stone room that emitted a faint medicinal fragrance. As soon as he entered the stone room, Xu Fan saw a large pill furnace in the middle of the room. There was even an Earth Flame next to the pill furnace.

Xu Fan was overjoyed. These two things were the things he had always dreamed of. He hadn't thought that they would suddenly be complete here.

It really was like looking for a place with broken iron shoes, getting it all without any effort!

Xu Fan walked over with great joy. He immediately picked up the pill furnace to look at it, but found that there were only some simple runes on it. He immediately had a look of disappointment on his face.

Even though this was his first time seeing a pill furnace, he had read a lot of refining knowledge from the 'Mysterious Sky Supreme Pill Scripture'.

Usually, the fewer runes on a pill furnace, the simpler it would be, which meant that the grade of the pill furnace would be lower. According to this situation, the pill furnace in front of him should at most be a low-grade magic tool.

But thinking about it in the blink of an eye, Xu Fan was happy. After all, he hadn't even practiced the most basic alchemy. Even if he was given a high grade alchemy furnace, he still might not be able to refine anything good.

"Forget it. I'm just refining some Body Refinement Liquid and refining the lowest grade of medicinal pills. This pill furnace can make do."

Xu Fan muttered.

In reality, this fellow had never thought that Gou Datong was just a rogue cultivator. A pill furnace with such a low grade magic tool could already be considered rich. This fellow actually thought that pill furnaces were too low in grade.

Afterwards, Xu Fan looked around and discovered that there was a stone table in the stone room. On the stone table was a jade bottle and a black storage bag.

Xu Fan opened the jade bottle and took a look inside. There was nothing inside, so he silently cursed the poor devil, then picked up the storage bag. At this time, not only had Xu Fan formed his spiritual sense, but he had also become extremely powerful.

In his storage pouch, Xu Fan discovered a jade slip, an incomplete secret manual, ten pieces of spiritual energy bearing stones he had seen before, more than ten Spirit Accumulation Grass, Spirit Attraction Grass, and some ordinary herbs. Then several hundred taels of gold and millions of banknotes.

"Looks like this unlucky fellow really needs some spiritual herbs to concoct pills. Otherwise, other than some spiritual herbs and some stones, there wouldn't be no pills left in this bag."

Xu Fan didn't carefully examine the jade slip. He conveniently put all of these things and spirit herbs into his Primal Chaos Tower, then searched around the stone room, but he didn't find anything else.

Xu Fan was slightly disappointed. Worried that Liu Da Feng would wait outside for a while, he walked out of the cave and handed all the silver notes he got from Gou Da Hong to Liu Da Feng, who was guarding at the door. "Big sister Da Feng, I plan to stay here and refine some things. Go back to Yan Xia City first, and while continuing to look for information, you'll also want to purchase a few types of Spirit Grass.

"Yes, young master!"

After watching Liu Da Feng leave, Xu Fan also turned around and walked into the cave.

"..."

When Liu Da Feng returned to Yanxia City, just as he returned to his own residence, he realized that his door was unlocked. He was shocked and immediately pulled out his spear. He stared at the door warily and shouted in a low voice, "Who is it?"

At this time, a low and dignified voice came from within the room. "It's me, Da Feng. Come in and speak."

Liu Da Feng was stunned. She looked around, sheathed her spear, and pushed open the door.

In the room, a man in black was sitting there. As soon as Liu Da Feng entered, he knelt down before the man in black. He called out to him in a low voice, "Master."

The masked man in black sat motionlessly as he said calmly, "Stand up and speak!"

"Yes!" "Old master!" Liu Da Feng responded and stood up, but did not sit in the chair behind him.

The masked man in black did not let Liu Da Feng sit down. He said: "How is the matter that I instructed you and your daughter to do?"

Liu Da Feng stood there and replied respectfully: "Master, it was lucky that the servant and father met with good fortune and found Young Master. However, my father …"

The black masked man did not seem to have any feelings, his voice was indifferent: "Alright! I understand, just follow me and protect him from now on. Also, you must think of a way to contact the third master as soon as possible and let him know that he's still alive. "

Liu Da Feng was stunned and said: "Master, you don't want to see the Young Master? "The young master, he …"

"Shut up!"

Liu Da Feng originally wanted to say something about Xu Fan's recent change, especially the fact that his strength had greatly increased, as well as the fact that he had an extremely terrifying weapon. However, before she could finish, he was coldly interrupted by the masked man in black: "Remember your identity, don't ask about things that you shouldn't ask.

"Yes!" Old master, I, your servant, will remember this! "

Liu Da Feng's heart sank. She lowered her head and answered quickly. When she looked up again, she found that the masked man in black had disappeared.

"Ai, young master …"

Liu Da Feng sighed and looked at the empty seat in front of him blankly. He did not say anything for a long time.

"..."

After the stone wall closed, it tightly covered the cave entrance. Not to mention ordinary mortals, even if it was cultivators using spiritual sense, they would find it very difficult to discover that there was a special cave behind the stone wall.

Walking into the stone room, Xu Fan was extremely excited. Everything was ready, and now the east wind was not lacking either.

"NND can finally break through the 'Brahma Monarch Stars Body Tempering Scripture'! "Yah, once I refine the pills, I can continue to follow the original method to raise the limit of my meridians and dantian, but I'm still lacking the pills to repair my meridians. It's a pity that the thousand year Head Wu gave it all to me, otherwise I could have refined a lot of Bone Ablutionary Dan Beads."

"Forget it, I'll just concoct the Body Refining Liquid first. I'll think about it after I break through to the < Brahma Monarch Stars Body Tempering Scripture >. Right now, I haven't even concocted any cultivation pills, so wanting to concoct a Bone Ablutionary Dan Bead is really too far of a waste. Besides, a medicine that's thousands of years old is not easy to find."

Xu Fan used his divine sense and arrived at the Seven Chaos Pagoda.

The next moment, he was stunned by the scene before him.

He hadn't been in the pagoda for more than ten days, but Xu Fan discovered that there was a huge change in the pagoda.

The first change was that the space once again increased by quite a bit, no matter if it was the total space of the tower or the area of the living soil. The second change was that the spirit herbs he transplanted into the pagoda from the forbidden area's valley had an astonishing growth potential, green and oily, emitting a lot of spirit energy. The most shocking thing was that he remembered that when the spirit herbs were first transplanted into the pagoda, most of them were less than twenty years old, but now they were all ripe, and one of them had a large number of seeds.

That is to say, the Spirit Accumulating Grass that was originally less than twenty years old had now all become thirty years old. The Spirit Attraction Grass that was originally only ten years old had now become Spirit Attraction Grass that was twenty years old and even the normal herbs now looked like they were at least twenty years old.

"What's going on? How could the age of these spiritual herbs suddenly increase by so much? "

Xu Fan was stunned. He thought to himself that he had only transplanted these spiritual herbs into the Primal Chaos Tower ten days ago. Thinking of this, a thought suddenly flashed through his mind: "Could it be because I planted these spiritual herbs inside the tower?" "So …"

The more Xu Fan thought about it, the more he felt it was right. That's right, he had only been in there for ten days, and these spiritual herbs just so happened to have grown by a decade. Didn't that mean that there was only one day in the outside world while it was only one year in the Seven Chaos Tower?

Thinking of this, Xu Fan couldn't help but be ecstatic in his heart. He felt as if his happiness was about to explode.

"F * ck, if I can get some medicinal herbs that are not too advanced in age to grow, won't it become a precious medicinal herb that will last for over a hundred years?" "Hahaha, your father is going to be rich, but there's actually such a heaven defying treasure …"

Xu Fan was so happy that he was jumping up and down. This guy accidentally discovered that the Chaotic Tower had the special effect of speeding up time. He couldn't help but laugh out loud in the stone room.

Xu Fan knew that with the Chaotic Seven Stars Tower, he would no longer lack spiritual herbs and herbs to concoct pills. As long as he had spiritual herbs and seeds, he wouldn't lack a large number of spiritual herbs and herbs of all ages.

Pills. Training. Increasing one's strength was just around the corner!

For a time, Xu Fan was filled with confidence. He had never been this confident. It was as if he could already see the hope of breaking through!

After quite a while, Xu Fan finally calmed down from his excitement. He picked the Spirit Accumulating Grass and Spirit Drawing Grass seeds off one by one, and then scattered them all over the remaining green-brown soil. After doing all of this, he suddenly remembered the fruit core and tree root shaped object that he had bought at the auction.

Afterwards, Xu Fan opened the box and began studying it, but after looking around for a long time, he still wasn't able to identify where these two things came from. He simply planted both the core and the root-shaped rhizome inside the pagoda.

Subsequently, this fellow planted the three Purple Sun Firefox Flowers, which he had obtained at a high price, in the mystical soil of the tower. Then, he clapped his hands and returned to the stone room.

"Oh right, didn't that Gou Da Hong still have another jade chip in his storage bag?"

Just as Xu Fan sat down and was about to start refining the Body Refinement Liquid, he suddenly thought of the jade slip and the incomplete secret manual he had found in the stone room. His heart stirred, and he took out the jade slip and took a look.

"..."

Although the current Xu Fan possessed a heaven-defying treasure like the Seven Chaos Pagoda and had unexpectedly obtained the two Ancient Classics, in reality, he was still an absolute rookie cultivator. Naturally, he was very curious about cultivation items.

The incomplete secret manual was a low grade Yellow Rank sword technique called "Wave Breaking Sword Tactic". This sword technique had a total of sixteen moves, but unfortunately, this incomplete secret manual was too powerful, only having eight incomplete moves.

After learning it, he would be able to injure the enemy with the sword, and could take the head of someone from 100 feet away. He couldn't help but feel lucky that he had used a sneak attack to kill Gou Da Hong; otherwise, if Gou Da Hong were to make the first move, he would probably be killed by the opponent's flying sword before he could even make a move.

"What a great item! In the future, I will have another method of attack."

Xu Fan secretly rejoiced, then picked up the jade slip.

Xu Fan didn't know what it was, so he flipped it over and over. After looking for a long time, he still couldn't find anything, but in the end, he suddenly remembered that he had used his spiritual sense to open the bag of holding. An idea came to his mind, and he attempted to insert his spiritual sense into the jade slip.

In the next moment, a proud smile appeared on Xu Fan's face.

As soon as his spiritual sense entered the jade slip, a lot of information immediately appeared in Xu Fan's mind, as if he was reading a book.

After the time it took to make a cup of tea, Xu Fan withdrew his spiritual sense from the jade slip. His face revealed a happy expression.

It turned out that this jade slip recorded the simplest alchemy technique in the world of cultivation — < Beginner Pill Refinement Technique >. In short, beginner alchemy techniques were the most basic, simplest, and most basic alchemy techniques and techniques.

This sort of elementary alchemy technique was very common in the cultivation world. It could be bought with a small amount of spirit stones, but to Xu Fan, it was like a precious treasure.

From the beginning to the end, there were only some simple pill refining methods on the jade chip. Even the pill formula only had one kind of pill refining method, the lowest kind of Qi Cultivating Powder. Although these beginner alchemy skills weren't even worth mentioning compared to the 'Mysterious Sky Supreme Alchemy Scripture' that Xu Fan had obtained, it could be said that he was more than a thousand miles behind. However, the simpler the method and technique, the easier it was for Xu Fan who had never refined a pill before.

There were a few recipes and methods that had never been heard of before in the cultivation world of the Profound Sky Continent, but the most basic things within this scripture were very few. There were many things that Xu Fan couldn't understand, and this was the reason why he was so overjoyed when he saw the < Basic Alchemy > on the jade slip.

Mysterious and profound items weren't necessarily suitable for the current Xu Fan. The skyscraper was even able to rise from the ground. For Xu Fan, who only had a rudimentary understanding of cultivation and was still a rookie, the < Beginner Alchemy > technique was undoubtedly the most suitable for him.

There was another key point. This < Beginner Alchemy > also recorded a simple spell called < Fire Control Arts >.

The Fire Control Spell was a spell that could control the changes in fire. Of course, this Fire Control Incantation was only a basic simple technique, but to Xu Fan, what he needed right now was just this sort of simple basic technique. Even if it was too profound, he still might not be able to comprehend it.

From the jade slip, he found out that with this' Fire Control Secret Art ', alchemists could control the shape and size of the flame through their skills, thus better controlling the temperature of the flame and increasing the success rate of refining pills. This was a spell that alchemists had to learn.

Originally, Xu Fan was a little worried that he wouldn't be able to master the refining techniques, especially the temperature of the flame. Now that he had coincidentally obtained this jade slip, he was simply overjoyed.

"Great, now I have a better chance."

Xu Fan muttered to himself, then once again sent his mind into the jade slip. He began to carefully study the Alchemy Arts and the Fire Controlling Technique.

Through studying the basics of alchemy techniques, Xu Fan gained a lot of benefits and gained a lot of knowledge on alchemy. In the past, he had read a lot of things in the « Mysterious Sky Supreme Alchemy Scripture » that he didn't understand, but now, he suddenly understood.

Xu Fan couldn't help but become more interested. He put his entire mind into the jade slip, completely forgetting about time.

Time silently flowed by. In the blink of an eye, several hours had passed since Xu Fan began his research. It wasn't until his stomach began to revolt that he was able to withdraw his spiritual sense.

Sigh, according to the "Exhibition Golden Arts", cultivators must reach the great circle of the Qi Cultivation stage before they can eat. Sigh, according to the "Exhibition Golden Arts", cultivators must reach the great circle of the Qi Cultivation stage before they can eat.

Xu Fan rubbed his stomach and sighed to himself.

Afterwards, this fellow took out some fruits, cooked food and even a jar of white wine from his storage pouch.

In his previous life, this fellow had always been drunk today. In his eyes, living was happiness, and every time he returned from a mission, he would enjoy delicious food, good wine, and beautiful women to his heart's content.

Ever since they had returned to Yan Xia City, Xu Fan had wantonly bought a lot of fruits, various delicacies, and cakes. He had also bought quite a bit of this world's wine.

When this guy didn't have any missions in his previous life, one of his favorite things he did was to take a bath in a bar, taste good wine, and then pick up beauties. In this world, this guy still wouldn't change his habits, but he still didn't have the chance to take advantage of pretty girls, so he didn't leave good wine behind. Ever since he had discovered that the fruit wine of this world still tasted so-so, he had bought dozens of jars and placed them in his pagoda. In any case, this fellow wasn't worried that he wouldn't have a place to place them. The Seven Chaos Pagoda had become Xu Fan's warehouse.

Xu Fan took a bite of the fragrant rabbit meat, then fiercely drank a mouthful of it while holding the jar of wine. His face immediately revealed an expression of incomparable pleasure and leisure.

"NND, it's a pity that there's no beauty by my side right now. If only I had a beauty accompanying me in drinking, then this life would be perfect."

Xu Fan sighed, his eyes looking up at the ceiling of the stone room. He couldn't help but think back to his good life in his previous life.

As a cultivator, he ate huge mouthfuls of meat while drinking large mouthfuls of wine. At the same time, he was also reminiscing about the beautiful life he had in his previous life.

Especially not too long ago, he had mercilessly killed more than ten people and gone through a bloody scene. If he had killed so many people and witnessed such a bloody scene, he might have already vomited to the point where he would not be in the mood to eat anymore.

Fortunately, Xu Fan killed someone in his previous life and then casually picked a bar or party to pick up girls. Otherwise, he wouldn't be able to adapt to this cold world where strength reigned supreme.

After an hour, Xu Fan finally had enough to eat. He then picked up the jade slip and began to study the < Beginner Alchemy > technique.

Under this type of research that he had almost forgotten to eat or sleep, the next day, Xu Fan spent more than ten hours studying the < Beginner Alchemy > technique to the point where he had almost completely mastered it. At this moment, Xu Fan's face was filled with an expression of comprehension and confidence. Next, he immediately began to study the [Fire Mantra].

The 'Fire Mantra' was a basic fire type magic technique. In fact, it was a method to control the changes in fire, mainly by changing the shape and size of the flame, and thus the temperature of the flame. It was similar to the function of a temperature regulator.

Of course, this spell wasn't very profound, it was only the most basic spell. Some advanced spells could not only change the shape and size of the flame, but could also change the quality of the flame.

Since this was the case, the《 Fire Control Secret Art》 was extremely important for beginner alchemists, especially for super rookies like Xu Fan. Pill refinement was a complicated process, and controlling the temperature was a basic requirement. Once the temperature was not high enough, it was basically impossible for the pill to be refined successfully.

Apothecaries used their mana to control the flames, achieving the goal of adjusting the temperature accurately in real time. Thus, during the process of concocting pills, the temperature requirement would be met at different times. This was also the most basic and essential technique that cultivators needed to know in order to concoct pills.

If it wasn't for the fact that this Gou Da Hong also knew some pill refining skills, and that the jade slip in his bag of holding just happened to contain the "Fire Controlling Technique", the basic technique for refining pills, otherwise, even if Xu Fan could get his hands on the pill furnace and the Earth Flame, he wouldn't have been able to refine a pill as he had planned.

In the end, his luck was still monstrous!

Several hours later, Xu Fan withdrew his divine sense from the jade slip and revealed a face of sudden enlightenment.

"So there's actually so much to pay attention to when concocting pills. It seems like I've thought too simply about concocting pills before. Thankfully I accidentally obtained this jade chip this time. Otherwise, I might not even be able to concoct pills."

Xu Fan muttered to himself, as the opening words of the 'Fire Control Secret Art' flashed through his mind, 'The refining of a pill's fire temperature is extremely important. The control of the fire temperature, the strength of the fire, and the stability of the flame are directly related to the success rate of the pill and the quality of the pill. The appropriate fire temperature can be used to refine and purify the medicinal materials better.

Xu Fan could be said to have benefited greatly from his research on the《 Fire Control Secret Art》 in the past few hours. He had already touched upon the basics of pill refining. Although he hadn't really tried refining a pill, his knowledge of pill refining had taken a big step forward.

In the remaining time, Xu Fan wasn't in a hurry to start refining pills, because he knew one thing. Only by getting familiar with and mastering the 'Fire Controlling Technique' would he be able to better control the pill's temperature and minimize the chances of mistakes and failures.

Of course, there was another reason. Xu Fan knew very well that he didn't have much alchemy material that he could use to practice and waste. Once he consumed and wasted those herbs, he would have to wait a bit longer to refine them.

As a result, after thinking about it again and again, Xu Fan decided to concentrate on cultivating the "Fire Controlling Technique". When he completely grasped the art of controlling fire, he would officially start concocting pills.

"..."
