Xu Ying's eyes lit up. If he successfully found the source, wouldn't that mean he had a steady supply of mysterious energy to use?

Even if he couldn't open the Mud Pill Secret, he could still absorb its activity and become a Nuo Shi, refining his Hidden Scenery!

He immediately entered a meditative state again, observing himself internally and entering the realm of Xi Yi within his body.

This time, Xu Ying's divine sense no longer followed the mysterious energy in the Xi Yi realm, but rather went against it and entered outside his body!

His consciousness flowed upstream and entered the water flow.

Various mysterious energies in the water formed turbulent currents, extremely dangerous. If he wasn't careful, his divine sense would be swept away and lose its direction.

Then, a bell rang out: "Young man, I'll use my bell to steady your divine sense!"

The sound of the bell rang in Xu Ying's ears, making his divine sense clear and stable, impervious to external interference.

Xu Ying seized the opportunity, passing through the turbulent currents and following the source of the mysterious energy in the cave, drifting further and further away.

It was as if he had passed through ancient spaces and entered an immeasurable world. The sound of the bell gradually became distant, as if separated by infinite space.

Xu Ying couldn't help but feel afraid. If his divine sense couldn't return, wouldn't he become a fool?

"My divine sense has followed the mysterious energy through time and space for so long, and still hasn't found the source. It seems that this is really a blessed land, not fake! Da Zhong must have guessed wrong!"

Xu Ying was about to return the way he came, when suddenly the sound of the bell became clearer.

He was stunned.

The clearer sound of the bell meant he was getting closer to his physical body!

But how was that possible?

His divine sense clearly followed the mysterious energy through countless time and space, traversing countless planes, as if he had traveled billions of miles. How could he be getting closer to his physical body instead?

Xu Ying's divine sense chased after the strand of mysterious energy into the Mud Pill Palace, arriving at the stone wall behind the palace. The source of the mysterious energy was within the wall.

Xu Ying withdrew his divine sense and leaped out of the water, quickly putting on his tattered clothes.

He went to see Yuan Qi, but the snake demon was still in the process of metamorphosis, so he went to the stone wall behind the palace.

The wall was covered in moss, no different from the other walls. Xu Ying looked around and saw that the mysterious energy was seeping into this wall and then disappearing.

He lightly tapped the wall, which was incredibly thick.

Xu Ying thought for a moment and said, "Da Zhong, come out for a moment."

Da Zhong flew out of his mind and asked, "What's the matter?"Xu Ying lifted Da Zhong by the nose and swung him viciously towards the stone wall. Da Zhong exclaimed, "What are you doing? Let me down! Bang! You bastard, I'll fight you! Clang! A bell can kill but not be humiliated! Clang! Clang! Clang!"

Da Zhong trembled, but the stone wall remained unmoved.

Xu Ying put Da Zhong down and approached the stone wall, pondering, "There is definitely a problem. Da Zhong was able to break the Golden Body of the City God, so ordinary stone cannot be harder than the City God."

Da Zhong quickly backed away from Xu Ying, still trembling with fear. "This guy has a violent tendency!"

At this moment, Xu Ying noticed a faint imprint on the stone wall, resembling a left palm print, but blurry.

His heart stirred, and he extended his left hand to cover the palm print.

The stone wall trembled slightly, then suddenly cracked open, revealing a narrow passage. Xu Ying stepped inside, and the stone wall continued to retract, piece by piece, as Da Zhong followed closely behind.

As Xu Ying walked forward, the stone wall continued to retract, until they arrived at a small stone chamber inside the mountain. The chamber was not large, only four zhang long and wide, and very simple, with only a cushion and a jade bed. There was also a skeleton on the cushion, dressed in a thin blue robe that was as thin as cicada wings. The skeleton sat there with its head bowed, its bony hand seeming to hold something, but there was nothing in its hand.

There were rows of bookshelves around the skeleton, but they were empty. There was also a pile of ashes in the corner.

"The mysterious energy in Qin Yan Cave comes from the skull of this skeleton!"

Xu Ying's heart trembled slightly, and he was about to approach the skeleton when he suddenly saw a pair of silk gloves and a snake-catching staff next to it. He couldn't help but be surprised, "It seems to be the belongings of a snake catcher! A snake catcher came here before us!"

A snake catcher uses silk gloves to catch snakes by their seven-inch point and uses a snake-catching staff to scare away poisonous snakes in the grass. Xu Ying himself used to be a snake catcher, so he was familiar with these two tools. However, after he became successful in his cultivation, he rarely used these two tools.

"This is the home of Yuan Qi's ancestors for three generations. They have been living here for more than three hundred years. How could a snake catcher enter Qin Yan Cave and find this place?"

As Xu Ying thought about this, he suddenly remembered the book he had read last night. It was a travelogue written by Yuan Qi's grandfather, and it was so boring that he fell asleep while reading it.

"I remember the book said that Yuan Qi's grandfather was chased by a snake catcher and fled to Qin Yan Cave, where he discovered a cave within the cave and found this Niu Wan Palace Cave Heaven."Xu Ying pondered, "Could it be that he didn't shake off the snake catcher? The snake catcher followed him and found the Niyuan Palace. This person must be extremely clever, even detecting the mysterious energy of Qin Yan's cave and finding his way here! So these books on the shelves must have been taken by him."

He looked at the ashes in the corner of the wall. The snake catcher couldn't take many books with him, so he burned the ones he couldn't take!

Xu Ying lamented, "The owner of this stone room is probably the owner of the Niyuan Palace that the girl in the coffin is looking for. He died in the stone room and left his legacy. The snake catcher came here by chance and obtained the legacy of his predecessor. He was afraid that others would find this place, so he burned it to ashes!"

Da Zhong flew around the bones for a lap, carefully sensing and said, "The mysterious energy does come from this person's skull. It seems that before he died, he used his own remaining energy to help people locate dragons and find the Niyuan Palace."

Xu Ying went to the ashes in the corner of the wall and flicked it with his hand. Suddenly, his eyes lit up and he pulled out a book that was mostly burned.

The snake catcher burned too many books, and this book was pressed at the bottom, where the flames couldn't reach. There were still a few pages left, and the words on it could still be faintly discerned.

Xu Ying carefully identified it, his heart pounding, and exclaimed, "This is talking about the method to open the Niyuan Palace!"

Da Zhong flew over and said, "The method to open the Niyuan Palace? That's not right. The demon woman I suppressed was a Qi Refiner, and she knew the owner of this place. The owner of this place must also be a Qi Refiner! In their era, the Nuo art hadn't appeared yet, so how could there be a method to open the secret treasure?"

Xu Ying was also puzzled and said, "Could it be that this skeleton is not the person the girl in the coffin is looking for? Wait, who is that snake catcher?"

He was lost in thought and suddenly said, "The Zhou family of Lingling also rose up more than three hundred years ago and later moved to the capital. The secret of the Zhou family is the Niyuan Palace. Could it be that the snake catcher who followed Yuan Qi's grandfather to Qin Yan's cave is the ancestor of the Zhou family?"

Da Zhong was also a little surprised and said, "Three hundred years ago, one person and one snake entered Qin Yan's cave, and three hundred years later, one person and one snake entered Qin Yan's cave. The two snake demons only found the white jade palace outside, but did not find the stone room in the wall. The two snake catchers both found the stone room. This is too coincidental."

Xu Ying looked around. When the ancestor of the Zhou family entered this place, there must have been a lot of books in the stone room, overflowing with knowledge of the Nuo art.The Zhou family ancestor took away the most crucial Nuo technique and burned what he couldn't take. The books he took with him eventually led the Zhou family to great success, transforming them from a small snake-catcher family in Zeroling to a huge aristocratic family!

"The Elephant Strength Bull Demon Fist that Yuan Qi's grandfather got was probably just a low-level demon technique that the Zhou family ancestor pitied him with and threw at him." Xu Ying thought to himself.

He carefully unfolded the pages of the ancient book and read it carefully. The text on the pages was incomplete, and he could only imagine the missing content.

The book said that the human body has six secrets, with the Mud Pill being the first, and the Chaos Round Egg being the Mud Pill's secret. However, the power it contains is magnificent and requires breaking through the chaos.

Drill a hole in the chaos, fish for the Mud Pill's vitality. When the cultivation reaches a certain level, another hole can be opened to delve deeper into the Mud Pill and fish for more vitality.

By doing this repeatedly, one can open nine layers of heaven and fish out all the power of the Mud Pill's secret.

And the way to break through the Mud Pill's secret is also very simple, just use all your strength to hit the Chaos Round Egg!

"This kind of thing does indeed require the help of a great Nuo."

Xu Ying put away the pages and thought to himself, "The Mud Pill's secret is in the brain. If one is not careful, they will open a hole in their brain and their brain will burst. Even with the help of a great Nuo, it is likely to be very dangerous."

"I can help you."

Da Zhong suddenly said, "I am very powerful. Even if I am seriously injured by a demon woman, a short burst of power is not something that a great Nuo can match. But I'm not doing this for free. I'll help you open the Mud Pill's secret, but you have to provide me with more blood and qi to help me heal."

Xu Ying glanced at it and hesitated.

Da Zhong was naturally very powerful. Even after being seriously injured, it could still withstand the attacks of Zhou Yihang and Xue Chenghuang, two great masters. It was even able to almost smash Zhou Yihang and Xue Chenghuang to death with just one hit.

What Xu Ying was worried about was that Da Zhong was too fierce. If it hit with all its might in his head, his head would probably not just open a hole, but explode.

"Nothing will be left above the neck, I guess," Xu Ying thought to himself.

Da Zhong, seeing him hesitate, said suspiciously, "Do you not trust me? Xu surname, I, Da Zhong, have experienced thousands of battles in my life. Do you dare not trust me? Who doesn't know that Little Stone Mountain's Zhong Ye is steady and well-regarded?"

Xu Ying hesitated and said, "Yes, yes. But how did the girl in the coffin escape?"

Da Zhong exploded in anger and shouted, "Someone clearly sabotaged me and rescued the demon woman while chaos reigned! These bastards have been plotting against me for a long time. They even went so far as to start a massacre, forcing the Nai River to change its course and attack Little Stone Mountain! Otherwise, why would I let the demon woman escape?"Xu Ying hesitated, and Da Zhong quickly said, "Let's leave the cave, and I'll show you my accuracy!"

Xu Ying walked out of the stone room and came to the Mud Pill Palace, only to find Yuan Qi still unconscious.

He left Qin Yan's cave and went up to the Wu Wang Mountain. With a cool breeze blowing, Da Zhong floated up and said, "Do you see that towering tree on the mountain?"

Xu Ying looked into the distance and saw a towering tree at the top of the Wu Wang Mountain, about thirty zhang high and very majestic.

Da Zhong said, "I will use my bell sound to destroy it. Watch carefully!"

Xu Ying eagerly waited and suddenly heard a loud bell sound that shook the space. The next moment, more than ten men and women were blasted out of the woods, dancing in mid-air.

Xu Ying was surprised, "Officials from Lingling! They actually found their way here!"

After a while, the officials landed and fell to the ground, causing the birds and beasts in the woods to scatter.

Da Zhong paused and said, "I sensed that someone was spying on us in the woods, so I changed direction and surprised them. A Ying, I have exhausted all the power I have accumulated over the past two days, the rest is up to you!"

After that, the big bell disappeared into Xu Ying's head.

The sound of footsteps came from the woods, and the more than ten officials with bruises and swollen faces walked out of the woods.

Xu Ying stood still and said calmly, "My cultivation has advanced greatly, and I have become a demon king. You are not my opponents."

The officials were eager to try, but a voice laughed and said, "Xu Demon King is an exotic species of the human race. It is reasonable that the officials are not your opponents after you have become a demon king. So this time, they don't need to take action, I will personally subdue you."

Xu Ying looked over and saw County Magistrate Zhou Yang walking out of the woods in a luxurious black silk robe.

"Unsheath your swords!" Zhou Yang said softly.

Xu Ying then noticed that each official was carrying a sword basket with more than ten swords inside. The officials stopped about thirty steps away from him, unsheathed the swords, and then quickly retreated.

Zhou Yang walked up and took out a seed from his sleeve, planting it in the center of the sword formation.

The seed quickly took root and grew into a towering tree that covered several acres, with long and flexible branches hanging down.

The tree danced like a demon, and the swords planted around it were unsheathed with a clang!

"This tree is called Fenghua. It is said to be a demon tree that has absorbed phoenix blood. Under my control, it will wield hundreds of swords and display my Zhou family's ultimate skill, the Zhou Tian Slash Demon Sword."Zhou Yang smiled faintly and said, "Xu Ying, as an official of Zeroling, I love the people like my own children. I can give you a way out. As long as you surrender, I will not only help you clear your name, but also make you an official."

"What do you want me to do? Become a dog official like you?"

Xu Ying came to a willow tree nearby, broke off a willow branch as thick as his little finger, and smiled, "Let me see how the ultimate skill that your ancestors obtained from the Qin Yan Cave compares to my own comprehension!"
