There were more than a dozen cultivators guarding the library, and one of them was a Hunter.
When he saw Lu Yin arrive, he opened the door without saying a word.
Lu Yin entered the library on his own. The entire library was dozens of stories high, and it was like a city. There were hundreds of millions of books scattered about, and there were even people who were responsible for organizing them.
Aside from Lu Yin and the people who were organizing the library, there were also a few scattered people reading something.
Lu Yin looked around and casually found a book that was closest to him. He casually flipped through it.
On one of the peaks of White Mountain, Long Kui retracted his gaze when he saw the book Lu Yin was reading. It was a very ordinary biography, and he shook his head. Lu Yin was not looking for cultivation books after entering the library. Instead, he was reading biographies. It was a pity that the princess did not have a good life.
Lu Yin did not know that Long Kui was monitoring him, but he did not need to know either. He could guess that someone was monitoring him. He did not immediately search for books that introduced this region of space, but instead read biographies. This was because these biographies would definitely introduce this region of space.
Gradually, Lu Yin began to understand this region of space.
He learned that this region of space was called the Astral Tree Domain, and he also learned that in the distance, there was an incomparably large tree that blocked his line of sight like a wall. Everyone called it the Mother Tree. This entire region of space, including the Middle Realm and the Peak Realm, had been pulled up by the Mother Tree. Beneath its feet was the most dangerous region of space, the Lower Realm.
He also learned that each realm was very large. Even though he could see the Mother Tree, that was because it was simply too large, and it was like a heavenly barrier. He could only see the Rainbow Bridge because it ran through three realms.
It would take a lot of time for an Envoys to travel across a realm. According to Lu Yin's calculations, the Top Realm, Middle Realm, and Lower Realm might not be smaller than the Outerverse of the Fifth Mainland. In fact, they might even be larger. This was because each realm covered the heavens.
He knew that the rainbow in the distance was the passageway that connected the Three Realms. He also knew that there was an incomparably huge python in the Mortal Realm that had coiled around the Mother Tree several times. It was also the Ancestral Mang that the White Dragon Clan respectfully called. That Ancestral Mang was indeed a Progenitor realm expert. It had existed since the ancient times when human civilization had been passed down. It coiled around the Mother Tree to survive. Most of the time, it was in a deep sleep and would occasionally wake up.
Lu Yin also knew that at the very top of the Mother Tree was the legendary Sovereign Realm, where several Progenitors resided. At the same time, there was also an incomparably gigantic Divine Eagle that lived there. This Divine Eagle was similar to the Ancestral Mang era, and it had also existed since the beginning of human civilization. Most of its time, it was in a deep slumber. However, this was treated as a legend, and many ordinary people were unaware of its existence.
He knew that this starry sky also measured one's strength based on one's battle prowess, and the number of battle prowess values was no different from that of the Fifth Mainland. The only difference was that the Fifth Mainland measured one's battle prowess with a gadget, while this starry sky measured it with a Cloudconnect Stone.
He also knew that there were many people in this starry sky with the surnames Liu, Wang, Xia, Bai, and Nong. These were all primeval surnames that reigned supreme in this starry sky. At the same time, he also knew that the four Scales of the Top Realm were divided into the White Dragon Clan, the Frigid Immortal Sect, the Shenwu Plane, and the Wang Family.
The Frigid Immortal Sect's main family was surnamed Bai, while the Shenwu Plane's main family was surnamed Xia.
In the Middle Realm, there was a seed garden that mainly belonged to the Farmer Clan, as well as a sword stele that was guarded by the Liu Family.
However, there was no Lu. There was no Lu, and there was no Lu at all. There wasn't even a mention of the surname Lu. Why?
They were all primeval surnames, so why wasn't there a Lu surname?
Lu Yin flipped through many biographies, but he discovered that there was no Lu surname. It was as if this surname had never existed.
It shouldn't have existed.
Could it be that the Lu surname didn't exist?
Could it be that the Lu surname wasn't a primeval surname?
No, the Fifth Mainland recognized the Lu surname as a primeval surname, so why wasn't it here?
This was too strange. Lu Yin flipped through the biographies, but he couldn't find any Lu surname.
Lu Yin closed the book and fell into deep thought.
This starry sky revered the primeval surnames, and the Fifth Mainland was hostile to the primeval surnames. Could it be that this starry sky was the Fifth Mainland's enemy?
There were many things that he couldn't figure out, but Lu Yin had no choice but to stop reading. He had read many books, and this did not match his rather lazy personality. The more he discovered something strange, the more he didn't dare to be careless.
In his opinion, this starry sky was far more dangerous than the Fifth and Sixth Mainlands combined. This was because there were an unknown number of Progenitors here, and there were also many powerhouses below the Progenitor realm.
This starry sky was rather dangerous.
He was now curious about the Ancestral Mang. How big was it?
How many times could it wrap around the Mother Tree?
Didn't that mean that the Ancestral Mang was long enough to pierce through the Outerverse's seventy-two weaves?
It was unimaginable.
Lu Yin felt a little dizzy, and he shook his head before walking out of the library. Just as he was about to leave, the Hunter guard raised his spear to block him. "Go back."
Lu Yin frowned. "What do you mean?"
The guard's tone was stiff. "Before Miss Xiaoqian left, she instructed that you should not leave the library."
Lu Yin's gaze turned cold. "Is this an order from Princess Long Xi?"
The guard did not reply.
Lu Yin was furious, as he did not want to appear like Zhang Yang, but he also could not allow a guard to bully him like this. If he went too far, then he would not be able to do so. If he appeared too weak, then it would be easy for him to arouse suspicion. As he thought about it, he grabbed the spear and used 150 Stacks in his palm.
Although the guard was a White Dragon cultivator, he was not a member of the White Dragon Tribe. He was just an ordinary cultivator who had been recruited by the White Dragon Tribe. How could an ordinary Hunter resist Lu Yin's 150 Stacks? Lan Si had relied on 150 Stacks to stabilize his position as one of the Ten Arbiters, and even an Enlighter with a power level of over 200,000 was not his opponent.
At that time, Lan Si had been able to deal with an Enlighter with a power level of over 300,000 with his bare hands.
The spear trembled as 150 Stacks traveled along the spear and forced the guard back. Even the hand that had been holding the spear was injured, and his wrist was twisted. He helplessly let go of the spear and looked at Lu Yin in shock.
Lu Yin grabbed the spear and pushed it forward with one hand. The spear spun in the void, and a fierce force swept out in all directions, causing the surrounding cultivators to spit out blood and retreat. The Hunter hurriedly tried to grab the spear, but Lu Yin's gaze turned cold. He casually waved his hand, and an enormous force sent the Hunter flying a thousand meters away. He crashed heavily onto the ground, and the spear fell to the ground at the same time.
Everything had happened in an instant, and no one in the library could react in time.
The surrounding guards were shaken, and they all looked at Lu Yin in shock. They had never thought that the rumored weak son-in-law would have such a powerful side to him. This strength should be enough to challenge an Enlighter. Who had said that the son-in-law was trash?
Lu Yin clasped his hands behind his back and walked out of the library. He glanced at the Hunter in the distance. "Can I come out now?"
The Hunter was terrified, and he stood up with blood at the corner of his mouth. He hurriedly half-knelt. "This lowly one was reckless. Thank you for your mercy, son-in-law."
"Thank you for your mercy, son-in-law." The surrounding cultivators bowed in unison.
Within the library, many people looked outside. They saw Lu Yin's back, but no one dared to say anything.
It seemed like this son-in-law, who had buried his head in books, had an unyielding side to him.
In the distance, Long Kui's cold expression softened a little. At least there was still some vigor left, and the difference in strength could be made up for. However, if there wasn't even any vigor left, then the princess's life would not be good.
At this moment, Xiaoqian arrived and looked at the kneeling guard in shock. "Son-In-Law, what happened?"
Lu Yin looked at her coldly. "Were you the one who forbade me from leaving the library?"
Xiaoqian shook her head. "I only told you to wait for me if you wanted to leave. I didn't forbid you from leaving." At this point, Xiaoqian understood, and she coldly glanced at the surrounding guards.
During this period of time, many people in White Mountain had been secretly mocking this son-in-law, saying that he was weak and incompetent, and that he would only be able to lower his head for the rest of his life. It seemed like it was no longer as simple as just mocking him, and it had even escalated to the point that someone was behind this.
At the same time, she was also rather surprised. She had also thought that this son-in-law was weak and easy to bully, but she had not expected him to have such an unyielding side.
"Son-In-Law, Xiaoqian will report this matter to the princess and let her handle it," Xiaoqian said, her tone much better than before.
Lu Yin nodded.
"Son-In-Law, please come with Xiaoqian. The princess invites you, and the Junior Ancestor wishes to meet you," Xiaoqian said.
Lu Yin raised a brow. Junior Ancestor was a title that he now understood. It specifically referred to a few youths who were recognized throughout the Cosmic Tree as having the potential to reach the Progenitor realm. They were supported by the greatest resources in the Cosmic Tree Realm, and they were known as junior ancestors.
The one who coveted Long Xi was the Frozen Immortal Sect's junior ancestor, Bai Shaohong. The White Dragon Clan also had a junior ancestor named Long Tian, who was Long Xi's brother.
Now, Lu Yin's brother-in-law had appeared.
In the Cosmic Tree Realm, the Mother Tree also had an age. Just like how ordinary trees were determined by their growth rings, the Mother Tree also had growth rings. However, they were not determined by years, but rather by epochs. Each epoch was equivalent to an additional year, which was known as the origin wheel. That day was known as the Origin Wheel Ceremony, as the entire Cosmic Tree Realm would decide on a candidate for the position of junior ancestor.
The position of junior ancestor wasn't held every year, or even every hundred, thousand, or ten thousand years. Instead, it had to be determined through the Origin Wheel Ceremony. The specific reason for the Origin Wheel Ceremony was not recorded in the books, but it might have something to do with the Mother Tree.
Becoming a junior ancestor would give one unimaginable resources.
This generation's Origin Wheel Ceremony had ended long ago, and Lu Yin could not compete for it even if he wanted to.
Not long after, Lu Yin saw Long Xi and a young man in front of her. He was handsome, and his facial features resembled those of Long Xi's.
The man had clearly just gone through a battle. His clothes were tattered, and there were a few injuries on his body. However, this was only an image and not the man himself. Lu Yin could not determine the man's strength through this image.
He subconsciously glanced at Long Xi's wrist. The Fifth and Sixth Mainlands should have had gadgets, but here, it was just a flat, round stone that looked very ordinary. He had noticed it before, and from the biographies he had read, he knew that it was called a cloudstone. It was similar to a gadget, but it was more convenient. It did not require a network, and it ignored distance. It could be used to communicate regardless of distance, and it could even measure one's power level.
It was a specialty of the Cosmic Tree Realm, but Lu Yin did not know where it was produced. If possible, he wanted to bring some back to the Fifth Mainland.
