After cleaning up the mess on the ground, Xu Fan's gaze fell on the Hundred Soul Banner on the ground.

Xu Fan had already personally witnessed the power of this strange little flag, and had even experienced it himself. It was truly extraordinary, able to attack and defend, and could be said to be a sharp weapon that could both attack and defend.

"Strange, isn't this Hundred Soul Banner a magic tool?"

Xu Fan frowned. He still didn't know enough to know what the Hundred Soul Banner was. Suddenly, a thought flashed through his mind. He remembered the Yin energy that had previously been stored away. It was also a very strange jade cylinder.

"Could it be that the method to use the soul flag is on the jade cylinder?"

Xu Fan put away the Hundred Soul Banner and immediately took out the jade cylinder that glowed with a blood-red light. He then curiously injected his divine sense into it.

"As I thought, there are methods to refine a soul flag and some special methods to cultivate it. However, all of these methods are demonic cultivation methods."

An hour later, Xu Fan was slightly startled. He held the jade cylinder in his hand and remained silent.

In this half an hour, he had read through the entire manual to find out what kind of demonic cultivation technique was recorded in the jade cylinder.

He had to admit that the cultivation method on the jade cylinder was very strange, causing Xu Fan to sigh in admiration. This guy really admired the intelligence of the seniors of the Demonic Cultivators. They actually thought of such a strange cultivation method.

According to the jade slip, once a cultivator cultivates a demonic cultivation technique, they would be able to greatly increase their cultivation level in a short period of time. It was said that someone had once cultivated these cultivation techniques. In just two short years, they had already reached the level of being able to contend against Aurous Core stage cultivators. Xu Fan, who had always been vexed over his breakthrough, felt his heart palpitate.

However, when Xu Fan saw the introduction, the fire that had just been ignited in his heart was immediately extinguished. According to the jade slip, the elder who had reached the Aurous Core stage within two years exploded and died within the third year.

"F * ck, isn't this demonic cultivation technique too abnormal?" "What a pity …"

After a long time, Xu Fan was able to resist the temptation of cultivating a demonic art, but he still couldn't help but let out a long sigh.

Honestly speaking, even though Xu Fan was shocked by the introduction, he was still a bit moved. But very quickly, when he finished reading the entire technique, he immediately tossed the last thought to the back of his mind.

It wasn't because this fellow had any sort of righteous or evil opinion. To Xu Fan, it didn't even matter to him, so it was just as evil.

It didn't matter if it was in his previous life or now, this guy had always been reckless. As long as he liked something, he didn't care even if it was unorthodox or not. As long as he didn't like something, he would not care about it.

In reality, the reason Xu Fan gave up was completely because of what one of the senior cultivators in the jade cylinder said. Although the progress of this demonic path cultivation method was very fast, it left behind many loopholes and hidden dangers. If one pursued speed, their dao heart must be unstable and their foundation too shallow.

Xu Fan had died once, so he naturally valued his life more than others. He didn't want to lose too much because of this. In the future, when he was on the path of cultivation, he would end up suffering a Qi deviation because of this demonic cultivation technique.

As the saying goes, in a hurry, one can't eat hot tofu. In any case, he was able to refine pills, and he also had the treasure known as the Seven Chaos Pagoda which had some sort of mysterious function.

As for the method to break through, this brat believed that he would be able to find the final method. Since this method had its drawbacks, it wouldn't be too late to find a method to cultivate it in the future.

However, although Xu Fan didn't plan on cultivating this technique for the time being, it didn't mean that he had given up on the jade cylinder. After all, from his point of view, this jade cylinder was very useful. Although he didn't need to practice demonic cultivation, he could still learn a lot of mysterious techniques.

The so-called spell was just a way to use spiritual energy. Whether it was for cultivators or for demonic cultivators, learning it wouldn't harm the body at all.

After a closer look, Xu Fan found that there were quite a few techniques in the jade cylinder that were quite useful. One of them was the technique to refine and use the soul flag.

Xu Fan was overjoyed and quickly sent his divine sense in to carefully study it. After an hour, his face revealed a happy expression.

It turned out that according to the description in the jade container, after refining this soul flag, it would be comparable to a high quality magic treasure or even a top quality magic tool.

However, Xu Fan discovered that when fighting with a Foundation Establishment cultivator like Qian Yilin, the person using the item wasn't as powerful as the description in the jade cylinder.

After thinking about it for a bit, Xu Fan began to understand. This was probably because the magic treasure hadn't been fully refined, so the Hundred Soul Banner could only display a portion of its power.

According to the jade box, the Hundred Soul Banner wasn't a normal magic tool used by cultivators, but a treasure used by demonic cultivators. However, refining a Hundred Soul Banner was very vicious.

The reason it was called the soul flag was because during the refining process, one needed to devour and refine 100 people's souls. At the same time, if these 100 souls were stronger, then the power of the soul flags they refined would increase.

One of the biggest differences between ordinary mortals and cultivators is that the souls of cultivators are much stronger than those of ordinary mortals. Therefore, the refining method mentioned that the best way to refine a Hundred Souls Banner was to devour the souls of cultivators, and the higher the cultivation, the better.

"What a pity!" If I had gotten this magic treasure earlier, I would have had the soul of a Foundation Establishment stage cultivator in the Hundred Souls Banner! "

Xu Fan suddenly thought back to the Qian Yilin he had killed. This fellow was truly whimsical. If he hadn't killed Qian Yilin, then where would he have obtained this treasure?

Xu Fan shook his head and put his hand into his pocket. Once again, he took out the black Hundred Souls Banner. The Hundred Souls Banner was only the size of his palm before it was activated, but once it was taken out, it immediately released a dense amount of Yin Qi.

Xu Fan first refined the soul flag for a while, then began to follow the method written in the jade cylinder. He muttered some words and tried to activate the soul flag.

In the next moment, the ghost fog in the soul flag suddenly began to move. In the blink of an eye, the room was filled with black fog and ghostly shadows.

For a time, the entire room was filled with the ghostly wails and the chilly winds.

Even though this guy had been reborn in this world for more than half a year, whether it was his knowledge of cultivating immortality or cultivating demons, he had long since abandoned his atheistic thoughts from his previous life. Plus, he had already seen Qian Yilin use this Hundred Soul Banner before.

However, at this moment, although this fellow clearly knew that this was an illusion caused by him activating the Hundred Soul Banner, he still couldn't help but feel a little nervous.

"As expected, it's amazing. It's too fucking weird. It's really something good!" "In the future, if I were to use this when fighting others, just the aura and illusions from it would be enough to scare a timid person to death!"

Xu Fan's eyes shone, and he secretly praised.

In reality, Xu Fan was right. It wasn't really possible to scare off a cultivator to death, but it was completely possible to affect their ability to display strength.

Illusion did not mean that it was harmless. Even if the heart knew that it was fake, when faced with such a terrifying scene, any other person would inevitably feel their legs go soft and their entire body break out in sweat.

Under the opponent's nervousness and fear, his strength would at most be 20 to 30% displayed. Wouldn't it be a lot more likely to win if he were to fight like this?

Standing in the ghost fog, Xu Fan's mind went blank, and his expression became serious.

Shortly after, he began to chant and continued to channel his spiritual energy into the soul flag according to the method described in the jade box.

After half an incense stick of time, Xu Fan suddenly raised the soul flag. He gently waved it and shouted, "Gather!"
