This is an extremely tall and dark cave. The stone wall is carved with patterns and shining with faint light. The Yin River behind them seems to be blocked by invisible obstacles. A water curtain of forty or fifty meters high and sixty or seventy meters wide formed behind them.

Chu Qing urged the boat to leave the ground, but the boat seemed to be absorbed and sank motionlessly on the ground.

"No flying." Chu Qing said in a deep voice, his spiritual consciousness tentatively leaving the boat, "the spiritual consciousness is not damaged."

Only Chu Qingkuang's voice echoed in the empty stone cave, and the three people's spiritual consciousness were released.

When Zhang Xiaohan's spiritual consciousness touched the rock paintings on the stone wall, he was shocked. The picture pressed to his heart instantly overlapped with the rock paintings on the stone wall. He seemed to hear a painful howl like a beast in his ear again.

In the middle of the rock painting on the left is the scene she saw when she refined the Immortal Heart, even more detailed than that scene.

A tall and burly monk was burning with flames. Among the flames, his horned head flew up, and a black blood sprayed out. His chest was thrown away by the sharp blade, and an equally black and blood-sucking heart was being grabbed on the tip of the knife, and a drop of essence and blood in his heart was being caught.

One hand was cruelly pulling out a vein from the chest, and the muscles close to the chest were spasming together, while the other hand pulled out a spine.

On the rock painting on the right, the flames on the giant's body had been extinguished. His dark skin was being peeled off from his muscles, and his eyes on the head that fell on the side were also dug out. His dark eye sockets looked up at the sky, as if questioning the sky's injustice.

The three of them were shocked by the rock painting, which clearly depicted the scene of the brutal son of the ancient demon world being brutally killed.

The cave was very quiet, only the light from the boat shield was scattered, and the faint light reflected from the stone wall.

After a while, Chu Qingkuang broke the silence: "Let's go out, wise man, you can leave the boat too."

The wise man frowned, as if he reluctantly retracted his gaze from the rock wall. He opened his mouth and a token flew out of his mouth and floated directly on the wise man's head. A soft light poured down from the token, covering the wise man.

Zhang Xiaohan and Chu Qingkuang's eyes narrowed, and the wise man said calmly: "This place is safe for you human race. If there is no pure yang energy to protect the body, once I leave, my body will probably burn like in a rock painting."

The wise man said, looking at Zhang Xiaohan and Chu Qingkuai's actions coldly, Zhang Xiaohan looked at the jade tablet curiously, his eyes slightly stunned.

Chu Qing glanced at the jade plaque, then lowered his head and took off the top-quality immortal stone, put it in the storage bracelet, and darkened the shield, and walked out of the flying boat one by one with Zhang Xiaohan. The wise man's body shook slightly and floated out of the small boat. Flying here is prohibited, but it is not that he cannot fly at all, but from the height of the wise man's flying, it is only one or two meters above the ground.

Standing in the cave, a small feeling arises naturally. Looking up at the top of my head, it seems unattainable. Looking back, the dark dark river water brings a strong sense of oppression. Looking forward, it seems that something is calling them in the unfathomable unknown.

"Smart, is this the scene of the fall of your emperor son in the Demon Realm?" Zhang Xiaohan's voice echoed in the hollow cave. The light from the boat shield disappeared, and there was a faint light on the stone wall of the cave. The rock paintings on the stone wall looked clearer.

"I don't know much about the ancient times than you. It's the first time I have seen these rock paintings." The wise man seemed to have answered Zhang Xiaohan's question, but there seemed to be no answer. She slowly flew along the stone wall for a week and looked at the pictures on the stone wall carefully.

"Is it this Qiankun token?" Chu Qingkuang sent a voice to Zhang Xiaohan: "She has sacrificed and recognized the master."

If the sacrificial spirit recognizes the master, the master will not die, or if he either uses his powerful spiritual consciousness to erase the spiritual mark on it, he will not be able to regain it.

"I haven't seen you, I'm recognizing your master." Zhang Xiaohan said.

The Qiankun Token will not easily recognize her master. On that day, the Qiankun Token had already recognized her master at the Shura Trial Field. How could he easily recognize her master?

"Smart, you said there is an immortal soul here, but from the rock painting, the emperor's corpse was broken down..." Zhang Xiaohan's head turned around the rock painting, "Is the immortal soul the drop of essence and blood?" No matter how you look at it, only that drop of essence and blood looks like an immortal soul.

"We'll know when we go ahead and take a look." The wise man said, and then floated towards the darkness ahead.

Zhang Xiaohan looked at the back of the wise man, held the corners of his mouth slightly upward, and stroked the storage bracelet with his hand. Just as the wise man sacrificed the Qiankun token, a mark suddenly appeared in the depths of her sea of ​​consciousness, and the token that had been silent in the storage bracelet for a long time also moved slightly.

As soon as the mark was released, it quickly disappeared, and no shadow could be found in the sea of ​​consciousness. It seemed that its appearance was to remind Zhang Xiaohan. Zhang Xiaohan let go of his spiritual consciousness, followed the wise man, and walked towards the darkness ahead.

Zhang Xiaohan has never walked through such a tall and spacious cave. The stone walls of the cave seemed to be as flat as if they had been rested by a sharp blade. They have been underground for hundreds of thousands of years, isolated by the Yin River, and they are still very dry. There is no moss on the stone walls, and the spiritual energy here is not very thin. The most rare thing is that it is clearly in the demon world, but there is no demonic energy.

But occasionally, Zhang Xiaohan and Chu Qingkuang felt that they were peeping at something, but when they searched again, there was no trace of it.

This kind of peeking is more like an identity scan, as if a formation from an ancient era is automatically activated every once in a while to find out the identity of the intruder.

Zhang Xiaohan's eyes were always open. When this feeling of being peeped out for the third time, she caught a trace of colorless spiritual power and quickly passed through the wise man in front, as if she also passed by Zhang Xiaohan and Chu Qingkuang at the same time.

If the wise man does not have a Qiankun token, will he touch some kind of mechanism formation underground?

The three people walked forward quietly along the passage. Rock paintings occasionally appeared on both sides of the stone wall. Strangely, the content of the rock paintings showed the massacres suffered by monks in the Demon Realm. However, all the slaughterers only had magic weapons and a pair of hands. From those hands, they could only determine that the slaughter was not a demon clan, but they could not determine that they were monks from the other four realms.

After walking about a cup of tea on this section of the road, the road ahead suddenly disappeared, and a stone wall as high as the two sides blocked them.

"No, why is there no road?" The wise man murmured. She could not fly higher, nor did she dare to touch the stone wall, but just looked along the stone wall.

After looking around, he turned around and stared at Zhang Xiaohan and Chu Qingkuang: "There must be a formation here."

Zhang Xiaohan looked at Zhizhe for a while, as if judging whether her words were correct or not, and then he looked up and observed the stone wall silently. Zhizhe's expression was a little nervous, and he kept turning with Zhang Xiaohan's eyes, occasionally looking at Chu Qingkuang.

Zhang Xiaohan turned around the rock wall for a while, then lowered his head and pondered for a while before looking up to the wise man, "We are walking together. Until now, fellow Daoist Chu and I are still in a state of mind. Except for what fellow Daoist said, there is an immortal soul here, but what is an immortal soul, what will happen if the immortal soul is lifted, or what is there in the secret underground, we don't know at all. At this time, the safety of the three of us has been tied together. As the wise man of the demon clan, fellow Daoist must have a special inheritance. If we still hide it from us now, we can only put our lives first."

The wise man's eyes rolled, and suddenly smiled and said, "It turns out that Fellow Daoist Zhang doesn't believe me yet."

Zhang Xiaohan snorted, not commenting.

The wise man smiled again and said, "I have received the inheritance, but so far, what I know is not much different from what fellow Taoists know. This is the first time I have entered here. The wise man of all generations has not had the chance to come in. Naturally, what he knows is all guesses. Otherwise, someone would have checked this place long ago, and the immortal soul should have been released."

"The wise man has been avoiding my questions, which makes me worried." Zhang Xiaohan said slowly with a long voice.

"Does fellow Taoist have a way to break the ban formation here?" the wise man suddenly said.

Zhang Xiaohan looked at the wise man with a expressionless face, neither nodding nor shaking his head, and showed a state where the wise man would not cooperate at all if he didn't say anything.

The wise man frowned and sighed slightly: "The two fellow Taoists have received my reward and promised to help me lift the ban on the Immortal Soul. Is Fellow Zhang planning to repent?"

Zhang Xiaohan snorted: "It's not kind to say this. I promised to come with you to help you lift the ban on the Immortal Soul, but you should also tell us the dangers in it, what exactly is the Immortal Soul? If the ban is lifted, you will encounter any trouble. You are the wise man of the demon clan and are ready to sacrifice for the demon clan at any time. I am not. We are also planning to return to the human world safely. If you hadn't said that there might be a passage to the human world, hum."

Zhang Xiaohan said and looked at Chu Qingkuang.

Chu Qingkuang said, "The rock paintings here seem to be about the moment when the emperor of the Demon Realm falls. The wise man should have something to add to this moment."

The wise man looked up at Zhang Xiaohan, then looked at Chu Qingkuang, and suddenly said with a righteous expression: "Emperor Qianyao and Princess Ling Su join forces to defeat the Demon Realm, and the fall of the Emperor's Son of the Demon Realm is naturally inseparable from them."

"Haha, Qianyao and Ling Su are both descendants of the emperor's son, so they can kill the emperor's son?" Chu Qing said with a cold sneer.

The wise man had no expression on his face: "What happened in ancient times? We can only hear from the inheritance rumors, and that's what I heard."

In the dantian, the wise man glanced at the corner of his mouth, then closed his eyes and ignored it. The wise man continued, "As for the immortal soul, I only know that it is stronger than the rest of the immortal body. Once the immortal soul gets rid of the suppression and returns to the demon world, it is possible to recreate the glory of the demon world. Moreover, the immortal soul will summon the rest of the immortal body. Once the immortal body is completely put together, the emperor's son can be resurrected from the dead. The responsibility of our wise man is to lift the ban on the immortal soul."

No matter how hard these words sound, they are all right, but for Zhang Xiaohan and Chu Qingkuang, who know the undead heart, there are many flaws in these words, especially the last sentence.

The purpose of the wise man from beginning to end is not to let the immortal soul reappear in the demon world. Her purpose is to use Zhang Xiaohan and Chu Qingkuang to destroy the immortal soul.

"What after it is lifted? We are human cultivators and the emperor's son is a disciple of the demon world. He must hate the human race to the core. I am afraid that once the ban is lifted, the first one is to kill us." Zhang Xiaohan continued.

The wise man looked at Zhang Xiaohan and Chu Qingkuang with a strange look: "It should be to find an existence that can be parasitic. You two think that the essence of me, the devil cultivator, will the choice of the body of me, or will the choice of the two people?"

Zhang Xiaohan hesitated for a while, turned his head to look at Chu Qingkuang, Chu Qingkuang nodded slightly, and the two of them exchanged silently for a while.

"Okay, I'll try." Zhang Xiaohan finally nodded and agreed. The wise man breathed a sigh of relief and moved away from his position.

Under the sight of the sky eye, there are grid-shaped spiritual power lines spread throughout the stone wall. The node where the spiritual power lines intertwine should be the attack point where the formation is located. Zhang Xiaohan raised his finger and was about to take action when he suddenly thought of something. The purple spiritual light flowed in his body and turned into red spiritual power at the tip of his finger.

A little red spiritual light was stimulated and landed on one of the nodes. The stone wall in front of him suddenly shaking like a ripples. Zhang Xiaohan tapped his fingers and dozens of red spiritual lights hit the stone wall one after another, dazzling and disorganized. However, after these spiritual lights entered the void, they were twisted and torn in front of the stone wall as if something was twisted and torn. Then a piece of the stone wall suddenly disappeared, revealing a bow-shaped gate that was more than ten meters high.

The light flashed above the door, forming a strange blood-red pattern, almost covering the entire stone door. In the middle of the stone door, there were two black bracelets that pressed the door.

As soon as the strange stone gate and pattern appeared, Zhang Xiaohan couldn't help but take a few steps back, and his heart pounded. This was the second time she saw this pattern. The first time was underground where the heart of immortality was. A talisman was like this pattern suppressing the heart of immortality.

"It's here." The wise man murmured with some suppressed desire in his voice, as if he was about to pounce on him and suppress him.

"The above is a talisman carved." Chu Qingkuang looked at the stone gate and frowned. He was not good at talismans. He carved talismans on the stone gate and used the entire stone gate as talismans. This was the first time he had seen them.

"Yes, it was a spell that was used when suppressing powerful people in ancient times." Unexpectedly, the wise man answered immediately.

"Can you crack it?" Chu Qingkuang asked at the wise man.

"What is used for writing talismans in this sect should be the essence and blood of the human race, and the immortal soul of the emperor's son should be the extraordinary human race blood. The ordinary methods may not be able to be broken." The wise man stared at the pattern on the master's sect for a while, shook his head and said in disappointment.

"Divin tells me that the arrival of the two human kings will bring unexpected conclusions." She said, her eyes wandering on Zhang Xiaohan and Chu Qingkuang.
