"Which way?" Zhao Jintong asked in a daze, still not fully sober.

The four women, including Lady Nine, had already stood up, their faces very serious. "Which floor is that tome on?"

"The fifth-floor attic." Feng Nichen replied.

Zhan Lunhuan frowned, "Why not put it in the attic on the sixth floor?"

The sixth-floor attic is enclosed by a barrier, making it difficult for not only students or instructors to enter, but even elders cannot easily enter.

Such an important book is actually placed in the fifth-floor attic?!

"It was the dean who put it there," Feng Nicheng said with a subtle expression. Then she said anxiously, "You guys watch here and seal the exit. Don't let any students out. I'm going to the fifth floor first."

"Okay!" Ninth Lady said solemnly.

Feng Nichen's figure flashed and disappeared in front of them.

At this moment, the students in the library felt a surge of mental pressure, causing them to experience splitting headaches. Because they couldn't speak, they could only stare at each other in astonishment.

What's going on?!

On the fifth floor of the library, Yun Zheng didn't expect that the ban on this old book would be suddenly lifted, so she was a little surprised.

She did not stand there stupidly, because something in this old book seemed to be calling her, and she quickly turned the page.

Her eyes paused slightly, and she saw that there was a piece of paper stuck in the old book.

Yun Zheng's fingertips accidentally touched the paper, and in an instant, the paper immediately turned into a ball of red mist and penetrated into her fingertips.

Her sea of ​​consciousness felt faintly hot.

"Master, this page contains the pupil technique corresponding to the fairy pupil level." Dajuan's excited voice sounded in her sea of ​​consciousness. From the beginning, the "Book of Pupil Techniques" was incomplete, because the content of the second half had disappeared. Now it was a blessing to be able to find a page back.

As the book spirit, Dajuan can clearly feel the lost page. After it came back, its strength seems to have increased a lot.

Yun Zheng frowned, she closed the book and saw the words written on it: "History of Changes".

She turned to the first page, and the more she read, the more complicated her expression became.

etc!

A breath of air was coming towards her quickly!

Yun Zheng made a decision quickly, put the book back to its previous position, then put an invisibility talisman on herself and left in the opposite direction.

As soon as Yun Zheng left, Feng Nichen arrived. She immediately squatted down and checked the abnormalities in "Records of Changes in History".

Feng Nichen's face was serious, the ban was indeed broken!

It looked like it had been read before, as there was still some warmth left on the book.

Feng Nichen put the "History of Changes" into the storage space first. She stood up and scanned the surroundings with her spiritual sense.

There are only ten people on the fifth floor of the library.

Who took it?!

Feng Nichen walked past rows of bookshelves and observed the expressions of the students who remained on the fifth floor.

The expressions of the first eight students were either frank or shocked by Feng Nichen's appearance, so she temporarily ruled out the eight of them.

There are two more people.

In the inner row, Feng Nichen walked into the aisle with a frown. When she saw the scene in front of her, she was stunned for a few seconds.

I saw a man and a woman sitting on a small stool, holding a book about swordsmanship, and seemed to be communicating with each other through voice transmission. The girl also used spiritual power to present the scene of the battle in her hand.

The two seemed to notice Feng Nicheng's appearance and looked towards her.

The girl smiled at her and nodded, her expression calm. The cold young man also nodded slightly.

Feng Nicheng's face was tense. She glanced at the battle scene presented in Yun Zheng's hand. It looked quite realistic and did not seem to be hastily condensed.

This little girl is the one that Jiu Niangzi and the others are waiting for.

Feng Nicheng pursed her lips and temporarily dispelled her suspicions about the two of them.

There were only ten people on the fifth floor of the library, and each one of them looked calm and composed...

Feng Nichen lowered her eyes to hide her hidden gaze, and disappeared from the spot.

The other students were still quite confused about Feng Nichen's appearance. When they thought about the mental suppression that had just erupted, they felt something was wrong.

Feng Xinglan and Yun Zheng looked at each other tacitly, and then continued to practice the Soul-Slaying Sword Technique.

Because Yun Zheng knew that the female elder had not left, and was observing their every move in secret. Once any clues appeared, she would be found out.

Although she didn't know what the consequences would be, Yun Zheng was sure that what she had just seen would definitely cause a huge storm in the Sky Continent.

otherwise……

This female elder would not be so cautious.

Fortunately, this female elder did not know swordsmanship, otherwise the battle scene she demonstrated would definitely be exposed, because what she demonstrated was the "Soul-Severing Sword Technique", and Lan was holding the "Unbreakable Sword".

…

About half an hour later, Feng Nichen completely left the fifth floor of the library.

Zhao Jintong was clearly sober now. He asked impatiently, "You've been gone for so long, have you found out who it is?"

"No."

Feng Nicheng shook her head and said seriously, "That person is hiding very well. However, I've thought about it. This "Chronicle of Changes" is in my hands now. Even if that person spreads the news, there is no evidence to prove whether it is true or not."

Zuo Bufan was an optimist. He said slowly, "It's okay if one person knows about it. Just don't spread it around."

Lady Jiu said, "Actually, I don't understand why the dean placed this book in the attic on the fifth floor?"

Jun Feng suddenly thought of something and smiled, "Who is the dean? He's the divine fortune teller of heaven. He must have predicted this day long ago for placing this book on the fifth floor."

They heard this and seemed to be thinking about it.

The dean often said that cause and effect are closely linked. How can there be effect without cause?

The cause sown by the dean will naturally lead to the result today.

Feng Nicheng suddenly said, "There are ten people on the fifth floor of the library, including that beautiful girl."

"She can go up to the fifth floor?!" Zhao Jintong was shocked.

"Why not?"

…

After Feng Nicheng left, Yun Zheng's heart relaxed.

Feng Xinglan didn't ask her what happened. After so many years together, he knew that if Zheng Zheng wanted to say something, she would say it, and if she didn't want to say it, no one could force her to.

Yun Zheng thought of what she had just seen and her brows furrowed slightly.

The contents of the pages were blurry and some words were missing.

The faintly discernible content reads: 1,300 years into the Guang calendar, a demon god suddenly descended upon the world, splitting the former main realm into three: Yaoguang, Shouming, and Qiongtian. However, the middle portion of the main realm fell away and disappeared.

When she saw this, Feng Nichen came over, so she didn't read any further.

What is the main world? In addition to the Qiongtian Continent, there are actually two equally powerful continents, Yaoguang Continent and Shouming Continent...

Yun Zheng lowered her eyes slightly, but why were the remaining pages of the pupil technique stuck in this "History of Changes"?

Demon God...

She had only heard of his title in the Demon-Slaying Battlefield in Zhongling Province, but she didn't expect to see it again in a book.
