In the next few days, Wu Yan never left the Five Elements Peak. After he cleaned up some of the private goods he had gotten in the medicine garden in the past few years, he hid in the earth fire alchemy room in the Five Elements Cave and opened the furnace for alchemy.

Yiqiē seemed to be very calm, and nothing bad happened. But for some reason, Wu Yan has always felt frightened these days.

The three copies of the Zhuji Dan materials given by Lei Chuang were refined and discarded by him in this state. Fortunately, with his skillful skills, he forced himself to calm down at the critical moment, and the last one was not scrapped.

After the first furnace was successfully refined, he obtained six fiery red dragon's eye sized Tsukidan, which made Wu Yan, who had always been a little uneasy, somewhat comforted. After putting away the Zhuji Dan, Wu Yan originally wanted to use the demon pill he bought in Huofeng Shanfang City a few days ago to refine some pills, but after thinking about refining the Zhuji Dan in the past few days, and seeing that his state was still not restored, he left the Earth Fire Alchemy Room.

That uneasy feeling always haunted him. Wu Yan was a little restless, walking around in the stone room. Taking out the array disk of the entire large array and placing it on the ground, Wu Yan stared blankly at the places where the spiritual light was shining everywhere on the array disk. There doesn't seem to be anything wrong with a qiē.

Restless and bored, Wu Yan simply gave up meditation and cultivation, took out all his storage bags, and began to organize his things.

Whenever he is in a bad mood or restless, tidying up things or unconsciously doing some rummaging and picking things can calm his feelings.

Start by pouring out the contents of the first storage bag. This storage bag is full of bits and pieces that are basically unusable.

A dagger smeared with poison, several martial arts cheats, some various poisons wrapped in paper, some poisonous weed seeds sealed in wooden boxes, and so on.

Rummaging through these things, Wu Yan remembered the hardships and sinister encounters he had just stepped into the road of cultivating immortals, remembered the pharmacist seal, remembered Xiaogushan, remembered Gushan Yunhai Cave, remembered Zhang Tao, remembered the Wang brothers, and remembered the bits and pieces of encounters in his youth.

Wu Yan had a peculiar smile on his face at the moment that even he didn't realize.

Cleaning and stroking these things over and over again, as if returning to more than ten years ago, Wu Yan felt that his feelings were surprisingly quiet.

It was a long time before he reluctantly put these things back into the storage bag.

After pouring out the second storage bag, Wu Yan was still unconsciously looking at these things over and over again.

Several incomplete books of exercises. One of them is half of the "Treasure Elephant Sutra" obtained after killing Yan and beheading, one is the "Spirit Insect Spectrum" sold to him by An Yingying, and a fragmented "Grass and Wood Sutra", and the last few are the exercises collected from several enemies that have been killed, most of which are useless. An unknown piece of metal the size of a book, this thing seemed to have been beheaded by Yan, and Wu Yan had never figured out what it was. However, this piece of metal was very strong, and even the Molin Sword could not leave the slightest trace on it, which made Wu Yan feel quite surprised. He also tried to find out the origin of the metal piece, but unfortunately nothing came of it.

Unintentionally, Wu Yan suddenly discovered that the color of this metal piece was very similar to the color of the strange metal book cover of the "Book of Plants and Trees", and, looking at the situation, these two things seemed to be made of the same kind of metal.

Wu Yan couldn't help but curiously put these two things together, held them up in front of his eyes and looked at them carefully. Suddenly, Wu Yan put the metal piece on the ground, and then made a very unexpected move.

He tore off the remaining paper on the metal cover of the "Book of Plants and Trees". Only the bare metal book cover of the "Book of Plants and Trees" remained, which looked a little nondescript, but Wu Yan's eyes showed a hint of strangeness.

He grabbed the strange piece of metal on the ground, and looked at the gap on the metal book cover, which was originally occupied by the paper, and it was indeed similar to the thickness of the metal sheet.

Wu Yan curiously inserted the metal piece along the side of the metal book cover and slowly inserted it into the book cover.

Suddenly, after the entire metal sheet was completely inserted into the crack of the metal book cover, suddenly, the metal sheet and the metal book cover strangely emitted a burst of dazzling black and white light, which automatically flew out of Wu Yan's hand and floated in the void in front of Wu Yan.

Wu Yan looked at the changes in front of him in surprise. I saw that the metal piece was strangely fused with the metal book cover. The metal book cover emitted a strange black light, the black light was constantly distorting and changing, as if it wanted to condense into something, and the metal sheet looked like the pages of a book, but at this moment it emitted a dazzling white light.

These two rays of light are actually very similar to the colors of the black and white sword rays that Wu Yan has practiced!

Wu Yan touched his chin and looked at the thing floating in the air in disbelief, which looked like a strange book. Suddenly, he made a move that surprised even himself.

Wu Yan shook his hand and shot a black and white sword light at the strange book that emitted black and white light in the air!

The sword stabbed the metal monster book without any hindrance. Wu Yan's face changed suddenly! The black and white sword light he shot out was strangely swallowed by the strange book!

Looking at the metal monster book again, it seemed that there was no other change except that the light was more dazzling and the black light writhed faster.

Driven by curiosity, Wu Yan continued to shoot black and white swords at the metal monster book one after another. The metal monster book, like a monster that can never be satisfied, continued to devour the black and white sword rays that Wu Yan shot, the white light became brighter and brighter, and the black light writhed faster and faster, and even the entire stone room was illuminated into a strange black and white color.

Wu Yan's face became more and more ugly. He even felt overwhelmed. The True Yuan mana in his body, because of the continuous beating of the black and white sword, was being consumed rapidly, and he saw that it was almost exhausted.

Just as he was in a dilemma, the metal monster book suddenly stopped absorbing the sword rays, and instead produced another strange change. I saw that on the page of the strange book, the white light suddenly shone brightly, and then, the black light emitted by the book cover, after a frantic twist, condensed into words the size of mosquitoes and flies in the white light, this strange situation, Wu Yan encountered it for the first time, and couldn't help but lean over and look at those black light words.

Beneath the strange book, there always seemed to be a layer of something invisible to the naked eye, holding it up and floating in the air.

Wu Yan couldn't help but reach out curiously to take the strange book and look at it carefully, when his hand touched the metal monster book, the light and words on the metal monster book seemed to have found an outlet, and in a moment, all of them frantically rushed down his arm towards his body!

In the blink of an eye, his body was densely covered with the weird black characters, making his whole person look indescribably weird!

Wu Yan was surprised and wanted to get rid of the strange metal strange book, but for some reason, the strange book was like a part of his body, tightly stuck to his hand, and he couldn't shake it off!

And at this moment, all the words on the strange book seemed to be transmitted, and all the black words on his body, as if they were guided by some kind of guidance, all swarmed towards his head, and all of them were forcibly poured into his mind whether he wanted to or not.

After a moment's effort, the strange black text on his body disappeared, and the metal monster book fell to the ground with a "click". Wu Yan collapsed to the ground, unable to move.
