From the outside world, the entire library hall covers an area of only four or five acres of land.

However, once you walk in it, you will feel that it is extremely wide.

This hall seems to contain some kind of extremely clever spatial formation, a bit like a formation like "Mustard Seed Na Sumeru", but a small place hides a huge space.

After wandering around the library hall for half an hour, Chu Chen gradually felt a trace of abnormality.

His keen sense suddenly sensed that something seemed to be hidden somewhere in the library hall, and he groaned slightly.

When he reached a dead corner near the bookshelf, he didn't turn a corner, but walked straight to the wall in front of him......

The moment he stepped out, it seemed to pass through a thin layer of prohibition.

Behind that "wall" was an even wider hall. The bookshelves are lined up ten feet high, and you can't see the edge at a glance!

This...... This library hall actually hides a bigger and wider book collection hall!

Chu Chen was slightly surprised in his heart. The hidden hall was so big that he walked in the middle of the huge hall, surrounded by huge bookshelves that stretched as far as the eye could see.

After walking for an hour, the surrounding scenery has not changed at all. He was dazzled by the rare catalogue of ancient books.

However, just as he walked to a corner of the main hall, a strange feeling suddenly surged from the depths of his heart. At that moment, he suddenly felt a chill all over his body, and a cool breath rushed from his spine directly to the back of his head, making him shiver solidly.

Huh? What's going on?

I don't know why, at that moment, Chu Chen's keen spiritual sense seemed to feel a breath full of dark, cold, and evil feelings flickering slightly in the void, and it quickly disappeared. (Baidu search update is the fastest and most stable)

The aura appeared too suddenly, and it disappeared too quickly.

So much so that when Chu Chen reacted, he didn't know if it was just his own illusion, or if there was really an evil aura.

How could this be? The Great Hall of the Medicine Palace's Book Collection was all set up with extremely clever ancient forbidden formations.

Moreover, the "Four Treasures of the House" itself has the effect of warding off demons and suppressing evil spirits.

It stands to reason that it is impossible for an evil monk to appear in this kind of place filled with the scent of "Xuanling Ink" ink. Because for the righteous people, the Xuanling ink fragrance has endless benefits, but to the people of the evil path, it is like a poison, and it is impossible to resist at all.

Is it a delusion?

Chu Chen slowed down his pace and walked towards the direction of the evil qi he sensed step by step.

As he walked forward, the dark, cold, evil, and tyrannical aura in the void became heavier and heavier, and in the end, he could feel it lightly even without spiritual sense.

This discovery surprised Chu Chen, if the Great Hall of the Medicine Palace's book collection was invaded by an evil Dao powerhouse, I am afraid it would cause an unimaginable catastrophe!

Thinking of this, Chu Chen didn't dare to slack off, and hurriedly urged his whole body to the extreme state, and cautiously walked towards the place where the evil qi was the strongest in his induction......

Airplanes!

Just as Chu Chen was about to move forward, a slight trembling sound suddenly came from the air.

The next moment...... The storage ring he was carrying in his hand suddenly trembled wildly.

Hmm, what's going on?

I thought I would be attacked, but I didn't expect the storage ring to change.

He could feel that something in the space inside the storage ring was frantically slamming into the entrance of the space, trying to break through the shackles of the storage ring.

What is it?

When Chu Chen opened the exit of the storage ring, a black light broke through the ring, and a black object was conjured in the void.

At first glance, it looks like some kind of fragment, about half the size of a palm. The whole body is dark in color, and there are some broken lines on it, which looks like some kind of broken talisman fragment.

This is......

Frowning and thinking for a moment, Chu Chen remembered where this thing came from.

When his Black Eagle clone evolved to a place that could penetrate into the Black Mist Valley sixty feet deep, he took out such a mysterious black remnant talisman.

All along, this remnant talisman had honestly stayed in the depths of his storage ring, and there had never been any movement, making him almost forget that there was such a thing, and now he suddenly remembered when he saw this remnant talisman fly out on its own.

The black palm-sized remnant talisman flew out of the storage ring, as if it had suddenly had an autonomous life, and the whole body emitted a pitch-black light.

This light was different from the black aura in Chu Chen's body.

Although Chu Chen's Lingquan is also black, it is full of a majestic and unfathomable magnificent artistic conception, which is a dignified and upright Xuangong.

However, the light emanating from this remnant talisman was actually filled with an incomparably dark, cold, and evil smell. It seems that there is a vicious evil ghost lurking inside, looking at the world with fierce eyes.

When the pitch-black light slowly spread, a sudden upheaval made Chu Chen stunned and shocked!

When the black remnants floated in the void, the ancient books on the tall bookshelves next to them seemed to be invisibly pulled, floating in mid-air and began to turn automatically.

With each turn of the page, the handwriting written by "Xuan Lingmo" on those pages began to fade away.

At the same time, thin ink threads began to spread out of the book one after another, constantly submerging into the remnants.

This...... This strange remnant talisman will actually devour Xuanmo's spiritual power on its own!

Chu Chen's surprise was not trivial, the speed at which the remnant talisman devoured the Xuan Ling Mo was very large, and it could swallow all the Xuan Ling Mo of several ancient books in almost one breath.

By the time Chu Chen began to react, he violently urged his spiritual power to suppress the remnants of the void, and the Xuanmo in hundreds of ancient books had already been devoured cleanly.

The ancient books were scattered on the ground, and the white porcelain paper with a pale cyan glow was snow-white and clean, and there was not a word left.

How so!

Chu Chen was really a little panicked at this point. As we all know, the "Four Treasures of Fang" has always been the carrier of human light, so it is blessed by the luck of the human race in the underworld, and is full of the heroic righteousness in the human light.

This majestic righteousness is incompatible with the evil path, the evil spirit of the demon path, and the demonic energy, and they restrain each other. Therefore, in this great hall full of the fragrance of Xuanling ink, it is generally impossible for anyone to appear in the evil way, for them, this is equivalent to a huge poison cave! However, the evil qi on this strange remnant talisman is not only not restrained by the vast righteousness contained in the Xuanling ink, but can independently devour the Xuanling ink, how pure is the evil qi on it?
