Great Sun Swamp.

Young Master Mu had already arrived at the deepest part of the abode.

"Looks like this place was once a cultivator's cave." Young Master Mu whispered.

He didn't sense a single trace of a cultivator's aura from this immortal cave.

Any cultivator's cave would leave behind a trace of aura. Even if a cultivator could wipe it out, this trace of aura would fuse with the world. The heavens and the earth shared this aura, and a rank 4 Spirit Emperor could detect it just by inspecting it.

In his previous life, Young Master Mu was a demon-level character. If the aura of an immortal cultivator existed here, then there was no way he would be able to escape his senses.

Although this was a martial artist's abode, Young Master Mu was certain that the abode's owner's cultivation must have reached a very profound realm, even surpassing the level of a grandmaster at strength transformation.

The Great Yang Swamp was very dangerous. In the depths of the swamp, there was a type of monster that was extremely powerful. If it wasn't for Young Master Mu having reached the late stage of Qi Refining, it would have been extremely difficult to reach this place.

The fact that a martial arts practitioner was able to build a cave abode here showed how powerful that cultivator was.

Entering the cave, Mu Shaotian discovered that this cave was very simple and crude, with only a single bed.

On the bed were three boxes.

Young Master Mu raised his hand and opened the three boxes. The items within the boxes landed in his hands.

"This is …" Young Master Mu's eyes narrowed as he stared intently at the three items in his hand.

Of the three items, one was a jade slip, the other was a purplish-gold short saber, and the last was a blue fruit.

Young Lord Mu's gaze fell on the jade slip and the blue fruit.

Young Master Mu placed the purple gold short blade into a space stone. Although the purple gold short blade looked extraordinary, in his eyes, it was nothing more than a mortal weapon.

As he picked up the jade slip, Young Master Mu couldn't help but reveal a surprised expression.

Young Master Mu was certain that the original owner of the abode didn't know the secret of this jade slip.

Because this was a cultivation jade slip and was an object in the world of cultivation. Only with spiritual will would one be able to see the contents of this jade slip.

As for the other blue fruit, Young Master Mu didn't know what it was called on Earth. But he knew that in the Eternity, it was called the Blue Phoenix Heart Fruit.

This was a fruit that was even more precious than the Dragon Meridian Fruit.

Young Master Mu couldn't help but feel that his destiny was truly too good. With this Blue Phoenix Heart Fruit, he would definitely be able to break through to the great circle of perfection.

As he put away the Blue Heart Fruit, Young Master Mu's eyes fell back onto the jade slip and he swept through it with his divine sense. He was also very interested in what was recorded in the jade slip.

China has quite a few legends of deities. If these legends were true, then the people that appeared on Earth were all a bit too strong.

Soon, everything that was written in the jade slip entered Young Master Mu's mind.

Young Master Mu's face was filled with joy.

This was actually a cultivation technique jade slip. To be more accurate, it was an auxiliary cultivation technique jade slip. It was called the 'Mysterious Ice Heart Formula'.

According to the records in the jade slip, this Mysterious Ice Heart Technique was only a third grade mental cultivation method.

However, what made Young Master Mu happy was that the biggest effect of this mental cultivation method was actually suppressing the inner demons.

Why did he have a heart demon?

The higher a cultivator's realm is, the more they are jealous of the heavens, so when facing heavenly tribulation, not only do they have to fight the heavenly tribulation, but they also have to fight the heart demon. If they fail, their body will die and their soul will be destroyed.

One could see how difficult the path of cultivation was.

Thus, when cultivators were undergoing heavenly tribulation, they would prepare many treasures and spirit artifacts. Only by blocking the heavenly tribulation would they be able to restrain their inner demons in peace.

In his previous life, Young Master Mu had no desire. His actions were directed at his own heart, so naturally, he wasn't afraid of the devil in his heart.

However, in this life, regardless of whether it was Bai Yanxue or Chu Mengyun, they were both his heart knots.

Although Young Master Mu was confident in his ability to fear the inner demons, as his cultivation level rose, the inner demons would grow stronger and stronger. No one could be sure if the inner demons could truly affect him.

And now that he had obtained this Sacred Profound Heart Formula, it was like a timely rain. Even if he had an inner demon, Young Master Mu was confident that he would be able to easily suppress it.

After putting away the jade slip, Young Master Mu took another look at the cave and left.

On the Great Sun Swamp, Young Master Mu was walking forward as if he were walking on flat ground.

Within the swamp, many monsters with four eyes stared at Young Master Mu. They constantly ground their teeth, wishing that they could swallow him down.

However, the scene of Young Master Mu killing their companions was still fresh in their minds; they didn't dare to approach him.

Under the watchful eyes of these monsters, Young Master Mu quickly left.

Of course, this was also Young Master Mu. If it was anyone else, even if they were a grandmaster at strength transformation, they would probably be devoured to the point that not even their bones would remain.

At the edge of the Great Sun Swamp.

Xiao Fan looked at the corpses as his eyes became bloodshot.

Aside from him, all the other people he brought with him had already been killed by the Bone Cave. Now, he was the only one left standing here.

He wanted nothing more than to tear the bone cave into a thousand pieces, but this was a master of strength transformation.

There was a saying in the world of martial arts: 'All below the Grandmaster level are ants'.

As you can see, he is only a late stage inner strength martial artist. How could he be a match for a late stage inner strength martial artist?

"What is it? Anger? You want to tear me into a thousand pieces? " The Bone Cave revealed a mouth full of yellow teeth, grinded his teeth and laughed: "Do you know why I left you behind?"

Xiao Fan stared fixedly at the Bone Cave.

"Because I like to see others trying to kill me, yet being unable to do anything about it while being in despair." The Bone Cave sneered.

"However, there's nothing to see if I keep you here now. I'll be a bit more merciful and send you off to accompany them."

The bone cave was no different from killing other people with a single finger. Even an expert at the late stage of inner strength would be crushed to death like an ant in his eyes.

Xiao Fan's eyes were filled with killing intent as he looked at the bone cave. He knew that there was no chance of survival in front of a strength transformation grandmaster, but if there was a next life, he would definitely tear the bone cave into countless pieces.

"Bam."

With a loud bang, Xiao Fan's face revealed a trace of joy.

As for the Bone Cave, its gaze was slightly focused as a cold light flashed within.

They saw Young Master Mu slowly walk out of the Great Sun Swamp and glance at the corpse on the ground. Then, his eyes fell onto the Bone Cave and his expression was indifferent.

"Puff, puff. I've never seen such a young grandmaster in Strength Conversion before." The Bone Cave disciple laughed.

"You killed him." Young Master Mu said indifferently.

"You're just a bunch of ants. It doesn't matter if you kill them. If you can give me what you obtained in the Great Sun Swamp, I might be able to beat you." The Bone Cave smiled sinisterly.

Xiao Fan couldn't help but clench his fist. This Bone Cave truly treated life like grass.

"Are you even worthy of letting me go?" Young Master Mu mocked.

A grand Demon Sovereign, a mere ant actually dared to speak to him in such a manner. If news of this were to spread, people would definitely laugh their teeth out of their wits.
