Bai Xinghe narrowed his eyes and quietly felt the vast galaxy flowing slowly by his side.

Li Yao also saw a light particle representing the "Heavenly Tribulation" flashing past his cheek.

Bai Xinghe slowly opened his eyes, his voice extremely old and ancient: "Imagine that now we are Liu Shuxing, a celestial scientist who was ten thousand years ago, and finally built an underground observatory. Through repeated deductions by three hundred super crystal brains, we deduced the real sea of ​​stars. For the first time, we clearly saw so many heavenly tribulations, flying around over our heads..."

"And then, what will we think?"

"What is the truth of the heavenly tribulation? Where did they come from and where did they go?"

Li Yao said: "The vast universe is of course not only a powerful civilization for us humans. Since we humans have all thought of weaponizing the heavenly tribulation, then the heavenly tribulation is very likely to be a weapon launched by a powerful civilization, with the purpose of destroying or eroding another civilization."

This is a hypothesis deduced by Li Yao on Tieyuan Star and Xiong Wuji.

Bai Xinghe was surprised again, stared at Li Yao meaningfully, and sighed: "My friend Li Yao, you are getting more and more surprised me. I didn't expect that in today's cultivation world, there are outstanding young people like you."

"That's right, after seeing the horror of the heavenly tribulation, it is a natural idea to regard the heavenly tribulation as a weapon launched by another civilization."

"However, many great worlds that have encountered heavenly tribulation have very low levels of civilization and do not have much threat to other great worlds, just like the flying star world five thousand years ago."

"Why are these unthreatening worlds being attacked by the heavenly tribulation?"

"Why are there so many heavenly tribulations that cruising in the entire sea of ​​stars? Is it a cosmic war involving hundreds of civilizations?"

"What kind of mentality does the civilization that has launched these heavenly tribulations come from?"

Li Yao thought deeply for a moment and shook his head honestly: "I don't know.

Bai Xinghe sighed and said, "Liu Shuxing is truly one of the most outstanding figures in the era of Xinghai Empire thousands of years ago. If human civilization still exists billions of years later, maybe they will forget the 'Emperor', but they will definitely remember Liu Shuxing!"

"Ten thousand years ago, Liu Shuxing sat in Shuxingzhai, under this vast galaxy. After thinking hard for several years, he finally deduced two and a half of the most important laws!"

Lee Yoo raised his eyebrows: "Two and a half?"

Bai Xinghe ignored him and stretched out a finger: "First, the resources in the universe are limited."

Li Yao was stunned and almost laughed out loud. What is this rule? It is clearly a fact that everyone knows!

The ancient world of cultivation 40,000 years ago was because the resources of the three thousand worlds were almost exhausted. Major sects fought with each other for resources and even created monsters like the "demon clan", which eventually collapsed.

Although it is said that "the sea of ​​stars is boundless", it is something that no one can tell whether the universe has boundaries, let alone that even if the universe is boundless, the resources that humans can control and utilize are always limited.

So, this is the right nonsense!

Bai Xinghe seemed to have expected his reaction and quickly stretched out his second finger and said, "Second, the chain of suspicion exists in the entire universe and all civilizations."

Li Yao frowned: "What is the suspicion chain?"

Bai Xinghedao: "Recalling the several confrontations we just made, that's the chain of suspicion."

"Li Yao, since you killed the only son who was so brave, you are now facing the threat of a cultivator. In theory, you should join forces with me, but why are you full of scheming along the way, and you have to fight with me at any time?"

"nonsense!"

Li Yao said. "Even if I want to join forces with you, who knows if you will stab me at any time!"

Bai Xinghe smiled and nodded, "Yes, for me, the same is true."

"I certainly know that it is the best choice for everyone to work together now. But who knows your real purpose? Who knows whether you will suddenly turn your back on me and stab me for some reason, I don't know?"

"Look, you don't want to kill me, but you are afraid that I want to kill you, so you have to make the plan to kill me at any time."

"I may not necessarily want to kill you, but I am also afraid that you want to kill me, and even more afraid that you think I want to kill you, so you can only take action first and kill me, so I can only take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take action first and take

"This is the chain of suspicion, which is a bit difficult to explain, right?"

"Now, let us break the chain of suspicion, trust each other completely, work together to fight against the immortal cultivators. I can make a blood oath of my inner demons and never kill you, do you believe it?"

Li Yao shook his head and said firmly: "Don't believe it!"

Before he finished speaking, he realized the terribleness of the "chain of suspicion".

Bai Xinghe nodded with satisfaction: "That's right. If you don't believe me, I don't believe you either. Even if you make ten blood oaths of the inner demons, I don't believe you! Our relationship is entirely maintained by the 'terror balance'."

"remember!"

"We belong to the same race, can communicate without any barriers, have the same thinking pattern and emotions, and we are also facing the threat of the same enemy. Here, we also have very rich resources, crystals, magic weapons, and potions, all of which are very sufficient."

"Under this situation, there is still such a chain of suspicion between us that cannot be broken!"

"What if all these favorable conditions are removed?"

"If there is no great enemy of cultivator who can change the conflicts between us; if the resources around us are about to dry up, only the last bottle of high-energy nutritional agent is left; if we belong to different races, we cannot understand each other, just like "

Bai Xinghe suddenly changed without any warning, turning into a big lizard standing up. The bumpy thick skin was covered with pustules, and rotten juice kept dripping between the folds. A "hissing" roared in his mouth, and he opened his teeth and claws at Li Yao!

Although he knew it was a vision transformed by Bai Xinghe, Li Yao couldn't help but jump up and unsheathed the dragon-chasing feather sword again!

As soon as the sword was unsheathed, his eyes were blurred. Bai Xinghe was still sitting cross-legged, looking at him calmly.

Li Yao's heartbeat was like a drum and sweating profusely. For the first time, he knew that Bai Xinghe's mental attack method was so powerful, so he gritted his teeth and said, "What are you doing?"

Bai Xinghe said lightly: "Just now, I turned into a very kind starry alien race, expressing my highest respect to you in a very friendly attitude."

Li Yao couldn't help but want to curse, that look like he is not human or ghost, so he is not kind!

After a moment, I understood the meaning of Bai Xinghe.

Different civilizations originate from different planets and evolved into different appearances under different environments. It is not possible to use the concept of human beauty and ugliness to distinguish the good and evil of another civilization.

"Bai Xinghe and I are both humans, with the same enemy and almost unlimited resources. We still distrust each other and guard against each other. If there is any abnormal movement, we will kill each other!"

"If it is different civilizations, the form of survival and communication methods are completely different. When we meet in a sea of ​​stars with limited resources, there is an unbreakable chain of suspicion between us. I don't know if the other party wants to kill him..."

Li Yao dared not think about it anymore.

Bai Xinghe said in a Senran: "Now you understand that the resources in the universe are limited, and there will always be chains of suspicion between different civilizations. Under the deduction of these two laws, there is only one result in the appearance of the entire universe."

"Liu Shuxing used a very vivid metaphor to describe his speculation."

"The universe is like a dark forest. Every civilization is a hunter lurking in the depths of the darkness. They must be careful and not make any sound, because in the deeper darkness, countless hunters are eyeing each other, waiting for them to reveal their traces."

"No matter what kind of alien race is found, it should be a fatal blow. Because the existence of the suspicion chain cannot truly cooperate with another completely different civilization. Even if the two civilizations temporarily cooperate because of means such as 'terror balance', this fragile balance is always easy to break."

Li Yao was silent.

The first terrifying balance between him and Bai Xinghe was broken in just a moment.

No, from the beginning, the first terrifying balance was the trap set by the White Star River.

Now, although the two sides have reached a second terror balance, who knows how long it can last?

"The dark forest theory has a loophole."

Li Yao thought for a long time and suddenly said, "There may not be a battle between civilization and civilization when they discover it!"

"Will there be such a possibility that a higher civilization has discovered a lower civilization that is so low that it will never pose any threat to them."

"So, is it possible for high-level civilization to treat such low-level civilizations as slaves, pets, cannon fodder, etc."

Baixinghedao: "Maybe there is, this involves the last half of the law proposed by Liu Shuxing, the 'Son of Destiny'."

Li Yaodaqi: "The law of the son of destiny? What is this? Why is it called 'half'?"

Baixinghedao: "The dark forest theory can basically explain the existence of the great heavenly tribulation, but it is a bit reluctant to explain the small heavenly tribulation."

When Li Yao thought about it, it seemed to be the same.

There are two types of heavenly tribulation. The one that happened in the Flying Star Realm five thousand years ago. It can destroy a planet or even a vast world is called the Great Heavenly Tribulation.

In the entire history of human civilization, the probability of the occurrence of the great heavenly tribulation is extremely low. The records in historical materials can be recorded at most two or three times, and most of them are confused with myths and legends, and may not be true.

More than the great heavenly tribulation, it is a small heavenly tribulation specifically targeting individuals, which is as numerous as a cow.

Many cultivators who have reached the Nascent Soul realm and who have reached the stage of God Transformation have encountered small heavenly tribulation.

In fact, in the ancient times of cultivation 40,000 years ago, most cultivators did not realize the existence of the "big heavenly tribulation". They only knew one kind of heavenly tribulation, which was the "small heavenly tribulation" targeting individuals!

If the great heavenly tribulation that destroys the planet is an attack issued by another civilization, what is the small heavenly tribulation?

There is not necessarily a civilization that is so boring, and if you are full, you will cross the vast galaxy and kill someone specifically? ——

Chapter 4 is here today!

One thing to be solemnly declared.

Although many book friends have seen it, there are definitely many book friends who may not know that the "Dark Forest" theory and "skeptic chain" are not original works by Lao Niu, but rather the concept proposed by Liu Cixin, a science fiction novelist who Lao Niu admires very much in the "Three-Body Problem" trilogy.

This is used to express Lao Niu’s respect for Teacher Liu Cixin, and please also ask all book friends to know.
Chapter completed!
