"Good thing." Li Yuan leaned out his hand, and under Elizabeth's surprised gaze, he grabbed the poisonous light in his hand and played with it at will.

"No, right? Boss, you are so powerful?"

"It's the Black Rubik's Cube that is powerful. It purified the poisonous light and I secretly did some tricks. Therefore, even if the purified toxins break out of the limit, they cannot cause harm to me." Li Yuan was a little proud. After the Black Rubik's Cube was promoted to a semi-god treasure, the control not only did not seem stagnant, but was more handy. Even this terrifying poisonous light could be controlled and formed into a slender bracelet and worn on his wrist.

"Huh, it's okay. God knows whether the black lotus can block the penetration of toxins." Elizabeth released a scanning ray. Since the treasure chest was opened, the scanning ray could go straight in.

After careful scanning, the thirteen treasure chests suddenly separated from light and shadow and floated in front of Li Yuan.

These lights and shadows are things created by Elizabeth, and they perfectly present the situation inside the treasure chest. Although the treasure chest is open, who knows if there is any danger? So the treasure chest is still in its original place, but Li Yuan can view what it is in through virtual lights and shadows.

Li Yuan snapped his fingers, and the treasure chest quickly faded away, leaving only the things that were filled inside.

"document?"

The first thing that caught your eye was the magnetic cards specially used to record files, full of three treasure chests, all filled with magnetic cards.

"Oh, are these documents useful?" Elizabeth jumped on Li Yuan's shoulder, his short and fat body and small arms swayed around him, and he didn't know where to grab the luminous symbols of fingernails. He raised his claws to connect the symbols, intertwined them into three circles of texture around his head, and slowly started to run.

Li Yuan stared at Elizabeth and said, "What are you doing?"

"Silly master, do you think the magnetic card can be browsed at will when placed in front of you? There is a powerful password lock on it. As long as there is something wrong, it will explode and destroy the recorded information." Elizabeth stopped talking, obviously decoding it seriously.

The three circles of texture composed of light talismans slowly contracted and condensed into a circle of things similar to a crown, worn on Elizabeth's head.

Li Yuan ignored him and continued to look at the treasure chest behind him.

"Huh, what's this?"

The treasure chest behind has no treasures, no magic treasures, and no familiar objects. They only store the same thing, that is, slices of black rocks the size of adults' palms.

It is not entirely true that the rocks are said to be. The slices have a metallic luster and the texture looks very delicate. Li Yuan tilted his head and pushed the virtual light and shadow into one place, trying to piece together the "black stone" with an extremely neat and smooth cut.

"Here, here again. If you are wrong, you have to go back. Hey, is it really one?" Li Yuan had just pieced together halfway through, and knew that all the black stones should be a woman, and a tall and beautiful woman wearing a retro palace outfit.

"Damn, Grand Duke Kuma has this hobby? Cut the woman's stone statue into slices and hide it. Is it a scam?" When Elizabeth came to his senses, he saw the black woman's stone statue and criticized sharply.

Li Yuan was lost intently and shook his head and said, "No, it's not an ordinary stone statue. She is the teacher that the first generation of Zero Academy students are obsessed with."

"What? The founder of Zero Academy?" Elizabeth jumped three feet high, extremely surprised.

"Yes, do you remember the Zero Academy model we found? It was a very interesting panoramic miniature record. I saw her appearance at that time. No, it was the breath, the breath was the same." Li Yuan hurriedly took out the Heavenly King Catalogue that he had not used for a long time and strode to the next to the treasure chest. He just used the holographic image to use the puzzle, and now he is truly restoring the original appearance of the stone statue.

The black stone slice was extremely heavy. With Li Yuan's strength, he actually had to rest halfway through. Finally, he was sweating profusely and gasping for breath before restoring the slice.

With a crisp "ding" sound, the stone statue slowly "stands" from the lying down.

At the same time, the Heavenly King Catalogue floating above Li Yuan’s head shines brightly, and a beautiful voice comes: "Satisfies the conditions, find the stone statue of the founder of the Academy, open the Zero Academy’s self-defense system. Discover the space road mark, infusing the power of time and space, and lifting the seal of the space maze."

"Click"

Li Yuan shook a few times and felt a thunder sound in his mind. Then, his mind gradually lost. No matter how Elizabeth called, he did not respond and his eyes lost focus.

The consciousness seemed to leave the body, pass through layers of fog, and return to Zero Academy.

Li Yuan stood at the place where he entered Zero Academy and imprinted the school emblem. A flower bed rose on the ground, filled with incredible metal flowers. A stone pillar stood in the middle of the flower bed, and a black stone statue slowly fell on the stone pillar and looked over gently.

"Stone statue? Zero Academy? How could I go back to Zero Academy?" Li Yuan shuddered and woke up.

"Ah, ah, ah"

Elizabeth was beating beside Li Yuan and shouting: "Master, you finally came back to your senses. For more than half an hour, you stood in front of me stupidly, and you didn't feel tired. Fortunately, your body was not hurt, and although your heartbeat was slow, it was still normal. Otherwise, I would have sent you into the mecha modulation nest for washing."

"Half an hour? How is that possible?" Li Yuan clearly felt that only a few seconds had passed, so why did Elizabeth say that half an hour had passed.

"That's right, I never fool people for half an hour." Elizabeth jumped on Li Yuan's shoulder again and pointed to the Heavenly King Catalogue that had been hanging high and said: "Master, look at the Heavenly King Catalogue. This thing broke out several times. It was light rain, tunnels, and galaxies. It seemed that it had received a large amount of information, but I couldn't read it at all, and even the cover was changed."

Li Yuan made a random move and felt a sank in his hand. The cover of the King of Heaven's Catalogue turned into a texture similar to that of a stone statue, with metallic luster on the edges. It seemed that something was hidden in the darkness. Looking at it intently, it was four serene words, "The Book of the Wise".

"Book of the Wise?"

I just muttered in my heart that the black cover of the King of Heaven, which is completely different from the original one, was opened and flipped "stop".

The book is full of blank pages. It was not until the last page that I saw something special. It was a key made of the space mark. Li Yuanqing couldn't help but reach out to touch it, and some information suddenly came into his mind.

"Use the space road mark I left at Zero Academy to condense a key, what a magical method." Li Yuan was very excited in his heart: "Okay, great, Zero Academy suppressed the Heavenly Prison and gradually expanded to form a space maze. Today, it has become quite large. As a student at Zero Academy, I found the statue of my teacher, and I also had the space road mark left at the school, and received a generous reward."

The happier Li Yuan looked at the black key on the page.

This is a powerful protection. Whether you fall into a trap or enter an alien space, even if you enter the dimensional universe, you can use the key to return to Zero Academy.

The most amazing thing is that he can use the key repeatedly and bring a few extra people to Zero Academy. Li Yuan will not return so soon. He still has a lot to do in the Demon Kingdom. Maybe he will enjoy a remote express delivery if he needs the recovery ceremony.

Of course, there is no limit at all, and it can only be used once every three months. In addition, it takes several seconds to start the key, and sometimes it is exactly those seconds that can kill people.

In addition to the convenience of returning to Zero Academy, this book of Wise Man also has many priorities.

"Book of the Wise"

Li Yuan rubbed his hands and was filled with joy: "It's amazing. This is a two-way prop book that allows the king of mechas to obtain the ability of actuaries and allow actuaries to display the power of the king. The Demon Kingdom has a Blood Coffin, which is also to allow actuaries with humble combat power to obtain the power of kings or above. However, this path is too extreme, and it is much gentler to use the Book of Wise. It is precisely because of gentleness that it seems valuable."

Suddenly, the page of the Book of Wise is flipping forward, and Li Yuanfu reaches his mind and takes out the ancient library memory crystal used to seal the three mechanical beasts of Tianxuan, Yaoguang and Yuheng, and seal it into the penultimate page.

The whole book only has thirty-six pages, but each page seems very heavy.

"Master, why did you seal Tianxuan and Yaoguang in? This book is really that amazing?" Elizabeth felt very strange.

"Well, the Book of Wise can indeed provide me with a lot of help, but it does not have artificial intelligence. If you take out a page to load artificial intelligence alone, you can convert it into a think tank in the book. The chips retained by divine forbidden-level mechanical beasts like Tianxuan, Yaoguang, and Yuheng are the more the better, and can increase the speed of the mecha amplification." Li Yuan closed the Book of Wise and was very satisfied.

"Haha, increase the speed of mecha calculation? Isn't this a treasure book tailored for me?" Elizabeth grinned, and he suddenly patted his head: "Look at me, I almost forgot the main business. The magnetic cards that store files were parsed out, recording many family secrets and handles, including the Kingdom of God, Demon Kingdom, Daxia, and the vassal states of the three ancient countries, with almost 50,000 copies."

"What about timeliness? Look at these treasure chests being covered in dust for a few years, can these files be used?" Li Yuan questioned.

"Hey, master, your thinking has become more meticulous. Is it the effect of the Book of Wise?" Elizabeth nodded and said, "I searched with the database and found that many files have expired. The family recorded on it was either shattered or was annexed."

After pausing his voice, Elizabeth praised: "The other party is very clever. It is like a small promotion system. Survival of the fittest. Those families that can withstand the test of time are more valuable. For example, the head of the family is a bastard, the family illegally possesses mineral veins, some families have killed important figures in powerful forces, etc. Some documents are super aggressive and can bring disaster to the entire family."

"Oh? You send the information of the three known ancient countries and vassal states to the Book of Wise, and then let Tianxuan and the others screen it." Li Yuan did not take the documents to heart, but he took out the thick fragments of the chains that bound the silver shuttle.

Grasp the fragments with your left hand and place your right hand on the Book of Wise.

Li Yuan's eyes lit up, and there was a lot of information in his mind. As the "buzz" sound spread, the Book of Wise Reaction and began to swallow the metal fragments of the chain and eat as much as it is given.
Chapter completed!
