No one was more knowledgeable than the Great Master on this point.
She looked at Lu Yin. "Apart from the difficulty of completely destroying the universe, what's more frightening is being swept into the River of Time."
After a pause, she continued, "The tributaries of the River of Time are born from the main river. If you want to pull them away from the main river, it will cause a huge commotion and cause the entire main river to resist. You can understand it as a counterattack, and it's easy to be swept away."
"Thus, it's normal for this mission to be rated Three Stars."
"The stronger the creature, the more they don't want to be swept away by the River of Time. Once they're swept away, they might be gone."
The Blood Tower Lord was scared. "Then why didn't you warn me?"
The Great Master said, "My universe has been completely destroyed, and taking me away won't cause much of a commotion. Besides, the tributaries have returned to the main river, and I'm just a ferryman. There are thousands of ferrymen in the area, and they won't pay attention to me."
Lu Yin understood. No wonder this mission was rated Three Stars.
It had nothing to do with the strength of a civilization, but it was related to the River of Time and the complete destruction of a universe.
"How do you completely destroy a universe?" Lu Yin asked.
The Blood Tower Lord's expression was solemn. "Back then, I accidentally saw that universe being completely destroyed. The scene was both magnificent and tragic."
The Great Master continued, "Extend the Sequence String infinitely until it melts into the area. It's like completely melting the universe, and everything inside dies and disappears."
"To the creatures inside, it's like a mouth that's always bigger and deeper than them swallowing them whole, and they can never escape."
Lu Yin's gaze sank. It sounded simple, and he could do it, but it was too cruel for the creatures in that universe.
Reboot the universe.
It was better than this.
It was obvious that the Great Master was recalling the past with a heavy heart.
Although the ferryman of the River of Time was not limited to any species and had seen many universes being rebooted and new lifeforms being born in batches, that universe was still considered her home, and even she could not let it go.
No wonder the Great Master was certain that it was not the Blood Tower Lord who had destroyed that universe.
The Eternal Life Realm could extend the string of the universe infinitely until it merged into the distance of an inch. However, the higher the cultivation, the easier it would be. Blood Tower Shangyu's cultivation couldn't hide from the Great Master when he completely destroyed the universe. If he wanted to destroy a part of the universe, it would take him a lot of time.
He was certain that he couldn't accept this mission.
Xue Ta Yu hesitated and said, "You said that since the unknown is capturing the tributary of the River of Time, then the one who completely destroyed that universe?"
"It can't be. Otherwise, I wouldn't be here anymore," the Great Master said.
Xue Ta Yu nodded. That was right. If it was done by an unknown person, the tributary of the River of Time would not be able to integrate into the mainstream.
But who else?
Why would he do such a thing?
Speaking of which, there were as many civilizations as there were stars in the sky. However, if the Blood Tower could find the universe where the Great Master was, it meant that the universe was not far from the three universes. This was worth thinking about. Who was the existence that completely destroyed the universe where the Great Master was? Would it be possible for it to attack the human civilization in the future?
However, it did not matter much. Even the Immortal Plume had been repelled, let alone the other civilizations.
That existence's strength would definitely surpass the Blood Tower Protector, but it was uncertain by how much. The three universes had experienced the unknown, the death universe, and the immortal feather universe. It felt like there was nothing they couldn't experience.
Lu Yin's consciousness entered Knowledge Tracker and found Eight.
Lustful, he directly rejected this mission.
"The mission to capture a tributary of the River of Time cannot be rejected," Eight Colors said.
Lu Yin was shocked, "I didn't agree to accept this mission."
"This is one of the compulsory missions."
"Missions can be compulsory?
Then why did you let me choose before? "
"There is more than one compulsory mission," Eight Colors said.
Lu Yin did not believe it, "Eight Colors, are you targeting me? The Immortal Plume was defeated, but it was not destroyed. The unknown still needs me."
"Every unknown now has to accept a compulsory mission, no exceptions," Eight Colors said.
"Is that so?" Lu Yin doubted it and then called the Immortal Master.
The Immortal Master must be in Knowledge Tracker. It did not dare to go anywhere for fear that the Immortal Plume would suddenly wake up and cause trouble for it.
Although the hidden danger in its body that could be discovered by the Immortal Plume had been eliminated, it would still leave a trace for a short period of time. It was extremely cautious.
"What mission did you accept?" Lu Yin spoke to the Immortal Master alone.
The Immortal Master did not hide it at all, "A two-star mission to draw a star map with a certain coordinate as the center. A radius of twenty years is the distance of an ordinary Eternal Realm."
Twenty years did not seem to be far. For an Eternal Realm, this amount of time was almost equivalent to no time. However, that was the radius of a circle with a coordinate as the center. To draw a star map completely clearly, it would take at least a thousand years or even more.
After all, it was necessary to fully explore that area of the starry sky.
Lu Yin did not expect that the unknown was actually drawing a star map.
This was only a two-star mission. There must be a higher-level star map drawing mission.
"Is this a compulsory mission?" Lu Yin asked.
The Immortal Master said, "I don't know."
"Ask Eight Colors."
"Okay."
They were talking alone. Logically, Eight Colors should not listen.
But Lu Yin did not believe that Eight Colors could not hear.
But hearing was just hearing. It could not be helped if the other party did not admit it.
Soon, the Immortal Master replied, "A compulsory mission."
Lu Yin's eyes flashed. A compulsory mission?
Capturing tributaries of the long river of time and drawing a star map. He always felt that the unknown was doing something very extravagant.
By the way, the unknown constantly wanted to add new creatures during this period of time. Was it to complete these compulsory missions?
But even if it was a compulsory mission, the unknown did not have a time limit. Then it would be fine if he did not do it.
Lu Yin did not understand.
If the mission was compulsory, it meant that the unknown was eager to complete it, but there was no time limit like before. It was too contradictory.
He had to find someone to ask clearly.
He called Damao, the old guy, and Che, but none of them were there.
Lu Yin was helpless. He could only look for them in the future.
Anyway, if the unknown wanted to do something, he would not do it. He would not lose out.
It was a pity that Lan Meng was dead. Otherwise, he would know everything.
Sometimes, qualifications were really important. At least, he knew more.
"There is one more thing."
Lu Yin pondered for a moment. He looked at the deep traces of knowledge and said to the Immortal Master, "When the hive civilization attacked the Lost Clan, which was the third stronghold. What happened?"
The third stronghold, the Lost Clan. Lu Yin had never forgotten.
Over the years, he would occasionally take out the Single Desert Card to take a look. The most puzzling thing was that he could not find the universe where the Lost Clan was.
That single Gobi Card was very powerful. It was almost an Eternal Life Level treasure, but it did not surpass the real Eternal Life Realm. After all, it was just a card. It was not easy for it to bring Great Elder Dan Gu and the others to the Tian Yuan Universe. They should not have gone far.
But …
Over the years, Lu Yin had explored the surroundings of the three universes many times, but he could not find the third stronghold universe.
It was as if this universe was not around.
If it was not, how could the Single Desert Card bring Elder Shan Gu and the others to the Tian Yuan Universe?
It did not make sense.
Either the third stronghold universe was not far away from the three universes, or the Single Desert Card had a method similar to teleportation and could move a long distance in an instant. The last possibility was that the third stronghold universe was completely destroyed.
Elder Shan Gu and the others would not know the result. When they escaped, the bugs were still in that universe.
So Lu Yin asked the Immortal Master.
The Immortal Master said, "That is not a universe at all."
Lu Yin was puzzled. "What do you mean?"
"The universe where the Lost Clan was indeed at war with us, and it lasted for a long time. I did not intervene in the beginning, so I did not see any difference. But when that ancient card escaped with a group of people, I realized that something was wrong. Of course, it was also related to the humanoid Green Immortal. It was the first to realize that something was wrong."
"After that card disappeared, the so-called third stronghold universe disappeared like a mirage."
Lu Yin was surprised. "It disappeared?"
The Immortal Master's voice was solemn. "Yes, it disappeared. It did not merge into the Square Inch and was completely destroyed. It did not move and disappear. It was just gone. It was as if it never existed."
"But during those years, the fight between the hive civilization and them was real, and it was definitely on one side of the universe."
"I have some understanding of the human civilization. The universe that was once destroyed recorded the glory of the human race. In those records, although the word 'human' was not mentioned, this form was recorded …"
The Immortal Master had said these words before.
Back then, before Lu Yin buried the Path Sword in its body, the Immortal Master had lost his memory. So, he repeated what he said again.
Back then, Lu Yin took the initiative to ask why the Immortal Master looked at the human civilization differently. Now, it was the Immortal Master who said it.
"The human civilization is very special. I knew that at that time, so I did not directly interfere in the war with the Lost Clan. I wanted to give birth to the humanoid Green Immortal so that the bug nest civilization could have a new direction of evolution. But I did not expect the Lost Clan to be defeated and leave with that card. That universe was also gone."
"It disappeared without a trace."
"I did not tell anyone about this. The only people who knew about it were the humanoid Green Immortal and myself. The others, including the Bug Lords, did not know. The reason why the outside world kept looking for the Lost Clan was that they were looking for the card. In fact, they were looking for the secret of the disappearance of that universe."
Back then, Dan Ji, a subordinate of one of the Four Insect Lords, had met Lu Yin outside the Consciousness Universe for the first time. Dan Ji had said that he was looking for an ancient card, and to Lu Yin, a card that had reached the level of Eternal Life was indeed very precious. However, it was only after he truly understood the Core Distance that he understood that the ancient card was not something that the Immortal Lords would covet.
So this was the reason.
What the Immortal Master was really looking for was the secret of the disappearance of that universe.
Universes could move, restart, and destroy, but they had never heard of it disappearing directly.
"Where are the coordinates of that universe?" Lu Yin asked.
The Immortal Master told Lu Yin the coordinates.
Lu Yin memorized the coordinates and was curious. "Why are you telling me this?
If you don't tell me, I won't know. Because you joined the unknown, I can't break the rules against you. "
The Immortal Master's tone was low.
"This is not something that I can meddle with. The more I understand your human civilization, the more I know that the only ones who can truly compete with you are those top-notch fishing civilizations, not creatures like me. If I rashly interfere, I will only die."
"Also, after so many years, I have searched countless times, but I still can't find the third barrier. Since that's the case, I might as well tell you. Consider it as me repaying you for exchanging rewards for the unknown to eliminate the hidden danger in my body."
