Xuan Nu followed Zhou Bai's footsteps without glancing sideways as they walked through the library. Zhou Bai's Primordial Spirit energy scanned the bookshelves, and the titles of the books surfaced in his consciousness.

The book that Dr. Zhuang mentioned is called "Miscellaneous Discussions of the Four Seas," and it requires a seventh-level clearance.

Although Zhou Bai had nominally defected from Donghua City and didn't possess such high clearance, he had just sent Xuan Nu to find the Grand Elder and managed to obtain a temporarily issued seventh-level clearance to access the books here.

The books that can be borrowed with seventh-level clearance aren't numerous. After all, besides the Daoist canons of the seventh realm, only a few profound Daoist techniques, martial arts, all historical records, and various miscellaneous confidential information meet this secrecy standard.

However, there aren't many people in Donghua City with seventh-level clearance. Zhou Bai had only encountered one person so far and had avoided them from a distance. His current situation was not suitable for meeting strangers.

"Found it."

Zhou Bai's eyes lit up, and with a move of his Primordial Spirit energy, he pulled out a book and held it in his hands. The cover of the book was indeed "Miscellaneous Discussions of the Four Seas."

'It's better if Xuan Nu doesn't see this to avoid seeing something she shouldn't and developing unnecessary distrust towards me.'

Thinking this, Zhou Bai looked at Xuan Nu and said, "Xuan Nu, help me keep watch; I need to check this book."

Then, with a move of his Primordial Spirit energy, the book flipped open. As his eyes scanned the content, his expression gradually turned solemn.

...

I am Zhuang Yan. If you are reading this book at this moment, you must have been summoned by someone like me.

If you have mastered the original power, then try using the method below to unlock the true content of this book.

...

Zhou Bai looked at it; there were some strange Dao techniques that gave a twisted, eerie feeling, as if one's hand had become a weird piece of seaweed constantly twisting.

Zhou Bai turned to the back and saw that the entire book was just an ordinary geographical record, describing the mountains and geography of Earth.

'Has the real content been sealed away?'

Zhou Bai thought for a moment and began forming the Daoist hand seals according to the method above.

As he moved his hands, Zhou Bai could feel a trickle of power from the void flowing into his hands.

Finally, along with the Daoist techniques, it was imprinted onto the "Miscellaneous Discussions of the Four Seas" before him.

The next moment, the text on the book squirmed and changed, forming a new content.

Zhou Bai looked down.

...

I once traversed every corner of the world, trying to investigate the origin of the void, the cause of the Heavenly Dao's distortion, and the secrets between demons and the Heavenly Court.

But as the investigation deepened, a particular person appeared amidst various clues and records. Various signs indicated that this world reaching its current state was inseparably linked to him.

That person is called Qing Yun Zi, the founder of the Three Pure Dao Sect and the first human in history to contact the power of the void.

His talent was unparalleled, creating many epoch-making powerful Daoist techniques, and he is revered by countless future generations.

But it was also because of his appearance that the proliferation of the void in the Material World and the rise of demons were precipitated.

I chased after his traces, searching everywhere for anything about him, and finally found a note from Qing Yun Zi in an ancient cultivator's tomb.

The content of which made me uneasy.

...

Zhou Bai turned to the next page and found that the book gradually turned into a strange material, looking like the records about Qing Yun Zi that Li Zhengdao had once given him.

'Could this be the ripped out records?'

Zhou Bai's eyes slightly shifted as he continued reading and found that the narrator had changed from Dr. Zhuang to Qing Yun Zi.

However, the content above was not continuous with the booklet Qing Yun Zi wrote that he read last time; it seemed to be just a missing part.

...

Before a colossal dragon, vast like mountains and almost occupying the entire sky.

A tiny human figure stood on the mountain peak like an ant, gazing at the dragon in the sky and said, "Zhu Long! If demons wish to survive in this world, the only way is to be accepted by the Heavenly Dao, otherwise, you will always be prey, slaves, food..."

Roar!

A soul-stirring roar echoes, the dragon glaring at the tiny human: "Absurd!"

Qing Yun Zi unwaveringly stared at the dragon, speaking each word clearly: "You have infinite adaptability, you possess the power to constantly evolve and adapt to the changes of Heaven and Earth, why not try cultivating Daoist techniques, comprehending the Heavenly Dao?"

"Only by becoming favored by the Heavenly Dao's fortune can you endure in the world. Otherwise, regardless of how strong a demon's life is, how long its lifespan, how large its numbers, there will be a day when they're all killed. But as long as you can comprehend the Heavenly Dao, there will be no more barriers between humans and demons."

"Ridiculous." Zhu Long coldly replied, "If you want to exterminate us, we will exterminate you first. Humans and demons cannot coexist, Qing Yun Zi, if not for the fact that you saved the mystical bird, I would have eaten you long ago."

...

Qing Yun Zi looked at the little demons before him, smiling as he said, "From today, you must learn to cultivate the Dao."

The cat girl beside him curiously asked, "Why do we need to cultivate the Dao? Clearly, we are demons; demons cannot cultivate the Dao."

Qing Yun Zi remained silent for a moment before saying, "Only by being recognized by the Heavenly Dao is the way to survive, or else everyone will die."

After saying that, he reinvigorated himself, smiling as he spoke to the crowd: "Demonic bloodlines can adapt to the various environments of Heaven and Earth, and can even adapt to and control the power of the void. As long as you find the right method, you can definitely cultivate Daoist techniques too."

In the following days, Qing Yun Zi took the cat girl and a group of little demons and continually studied the mysteries of demonic bloodlines, hoping to use their strong adaptability to gradually lead them from the demon path to the human path.

...

"Why?"

"Why?"

"Demons can clearly adapt to every environment between Heaven and Earth, even mastering the power of the void... Why on earth can't they be accommodated by the Heavenly Dao?"

At this moment, Qing Yun Zi's hair was disheveled, and his face was full of a beard. He also appeared much thinner, his face showing all kinds of confusion, bewilderment, and doubt.

As he spoke, Qing Yun Zi's eyes turned completely black as if he were seeing some scenes beyond the vision of ordinary people. His mouth uttered bizarre sounds incomprehensible to anyone else.

The cat girl beside him held a little girl in her arms, and watched him with a face full of concern: "Chenyang, are you alright?"

Darkness in Qing Yun Zi's eyes slowly gathered as he covered them, saying with an unpleasant expression, "I'm fine."

The cat girl worriedly said, "You've been 'absent-minded' more often lately, and last night you kept talking in your sleep."

Qing Yun Zi let out a bitter laugh, shook his head, and looked towards an empty corner, muttering: "How can I succeed... how can demons achieve what you say..."
