Bai Xinghe narrowed his eyes, quietly sensing the vast galaxy slowly flowing past him.

Li Yao also saw that a particle of light representing the "Heavenly Tribulation" flashed next to his cheek.

Bai Xinghe slowly opened his eyes, and his voice was extremely old, clumsy: "Imagine, now the two of us are the Heavenly Tribulation Scientist Liu Thorn Star 10,000 years ago, and finally built an underground observatory, through the repeated deduction of three hundred super crystal brains, the real sea of stars has been deduced, and for the first time, I can clearly see so many heavenly tribulations, flying around above our heads......"

"And then, what do we think?"

"What is the truth of the Tribulation? Where did they come from and where are they going? ”

Li Yao said: "The universe is vast, of course, there is not only one powerful civilization of our human race, 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 in order to destroy or erode another civilization." ”

This is the hypothesis that Li Yao deduced together with Xiong Wuji on the Tieyuan Star.

Bai Xinghe was taken aback again, stared at Li Yao meaningfully, and sighed: "Little friend Li Yao, you are more and more surprising to me, I didn't expect that in today's cultivation realm, there are still outstanding young people like you. ”

"That's right, after seeing the horror of the Apocalypse, it's natural to think of the Apocalypse as a weapon fired by another civilization."

"However, many of the Great Thousand Worlds that have suffered from the Heavenly Tribulation have a very low level of civilization, and there is not much threat to other Great Thousand Worlds, just like the Flying Star Realm five thousand years ago."

"Why are these threatless worlds being attacked by the Heavenly Tribulation?"

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

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

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

Bai Xinghe sighed and said, "The Willow Thorn Star really deserves to be ten thousand years ago. In the era of the Star Sea Empire, one of the most outstanding characters, if human civilization still exists after hundreds of millions of years, he may forget the 'emperor', but he will definitely remember the willow thorn star! ”

"Ten thousand years ago. The willow thorn star is sitting in the thorn star fast, under this vast galaxy, meditating for several years, and finally deduced two and a half, the most important law! ”

Li Yao 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 for a moment, almost laughing, what kind of law is this? It's a fact that everyone knows!

The ancient world of 40,000 years ago. It was because the resources of the three thousand worlds were almost exhausted, and the major sects fought with each other for resources, and even created monsters like the "Demon Clan", which finally collapsed.

Although it is said that "the sea of stars is boundless", whether the universe has boundaries or not is something that no one can say, not to mention the resources that human beings can control and use even if the universe is boundless. Always limited.

So, that's the right nonsense!

Bai Xinghe seemed to anticipate his reaction. 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 chain of suspicion?" ”

Bai Xing Dao: "Think back to the few encounters we had just now, and that was the chain of suspicion. ”

"Li Yao, since you killed the only son of the stormy one. Now that you are facing the threat of immortal cultivators, theoretically speaking, you should join forces with me, but why are you so scheming along the way, and you have exhausted your skills. Want to get your hands on 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, "That's right, as far as I'm concerned, it's the same situation. ”

"Of course, I know that it is the best choice for everyone to work together now, but who knows your true purpose, and who knows if you will suddenly turn around and stab me for some reason, I don't know?"

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

"I don't necessarily want to kill you, but I'm also afraid that you want to kill me, and I'm even more afraid that you think I want to kill you, so you can only kill me first, so I can only strike first before you make a strong move!"

"It's a chain of suspicion, and it's a bit of a mouthful to explain, isn't it?"

"Now, let's break the chain of suspicion, trust each other completely, work together, and work together against the immortal cultivators, I can make a blood oath that I will never kill you, do you believe it or not?"

Li Yao shook his head and was categorical: "Don't believe it!" ”

Before the words fell, he realized the horror of the "chain of suspicion".

Bai Xinghe nodded with satisfaction: "That's right, if you don't believe me, I don't believe you, even if you swear ten heart demon blood oaths, I won't believe you!" Our relationship is all maintained by the 'balance of terror'. ”

"Remember!"

"We belong to the same race, we can communicate without barriers, we have the same thinking patterns and emotions, and we are also facing the threat of the same enemy, here, we also have very rich resources, spars, magic weapons, and potions, all of which are very abundant."

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

"What if, all these advantages?"

"If there is no great enemy of immortal cultivators between us to divert the contradictions; If the resources around us are about to be depleted, only one last bottle of high-energy nutrients remains; If we're of different races and can't understand each other, it's like—"

Without warning, Bai Xinghe changed abruptly, turning into a large lizard that stood up, its pimpling thick skin was covered with pustules, and rancid juice was constantly dripping between the folds, and a "hiss" scream came out of his mouth, opening his teeth and dancing claws towards Li Yao!

Although he knew that it was a vision conjured up by Bai Xinghe, Li Yao couldn't help but jump up, chasing the dragon and turning the feather knife out of its sheath again!

As soon as the war knife came out of the sheath and the flowers in front of him, Bai Xinghe was still sitting cross-legged, looking at him calmly.

Li Yao's heart was beating like a drum and sweating, and he knew it for the first time. Bai Xinghe's spiritual attack was so powerful, he gritted his teeth and said, "What are you doing?" ”

Bai Xinghe said lightly: "Just now, I transformed into a very kind starry sky alien race, and I would like to express my highest respect to you with a very friendly attitude. ”

Li Yao couldn't help but want to scold, that person was not a ghost or a ghost. Where is the kindness!

After a while, he understood the meaning of Bai Xinghe.

Different civilizations, originating from different planets and evolving in different environments, cannot use the concept of beauty and ugliness of human beings to distinguish the good and evil of another civilization.

"Bai Xinghe and I are both human beings, and we have the same great enemy. There are also almost unlimited resources, still distrusting each other, guarding against each other, and killing each other at the slightest change! ”

"If it is different civilizations, the forms of existence and communication methods are completely different, and they meet in a sea of stars with limited resources, and there is a chain of suspicion between them that cannot be broken. I don't know if the other party wants to kill me......"

Li Yao didn't dare to think about it anymore.

Bai Xinghe said: "Now you understand, the resources in the universe are limited. And between different civilizations, there will always be a chain of suspicion, and under the deduction of these two laws, the appearance of the entire universe will have only one result. ”

"Willow Thorn Star 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 darkness, and they must be careful not to make a sound, because in the deeper darkness, there are countless hunters eyeing each other. Wait for them to reveal their tracks. ”

"No matter what kind of alien race is found, it should be dealt a fatal blow as soon as possible, because of the existence of the chain of suspicion, no one can sincerely cooperate with another completely different civilization, even if occasionally because of the 'balance of terror' and other means, the two civilizations temporarily cooperate, but this fragile balance is always easy to break."

Li Yao was silent.

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

No, from the very beginning, the first balance of terror was a trap set by the White Star River.

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

"The Dark Forest Theory, there's a loophole."

Li Yao thought for a long time, and suddenly said, "Between civilization and civilization, you may not have to fight to the death as soon as you find out!" ”

"Is there a possibility that a higher civilization has discovered a lower civilization and that it is impossible for them to pose any threat to them?"

"So, is it possible for a high-level civilization to treat this low-level civilization as a slave, a pet, cannon fodder or something like that?"

Bai Xing Daodao: "Perhaps, this involves the last half of the law proposed by Willow Thorn Star, the 'Law of the Child of Destiny'. ”

Li Yao Daqi: "The Law of the Child of Destiny? What is it? Why do you say 'half-strip'? ”

Bai Xing River Channel: "The Dark Forest Theory can basically explain the existence of the Great Heavenly Tribulation, but for the Small Heavenly Tribulation, it is a little reluctant to explain. ”

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

The Heavenly Tribulation is divided into two kinds, the one that occurred in the Flying Star Realm five thousand years ago, and can destroy a planet or even a large world, it 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, and there are historical records, at most two or three times, most of which are confused with myths and legends, and may not be true.

More than the Great Tribulation, there are small Tribulations that are specifically aimed at individuals, and this is like a cow's hair.

Many cultivators who have reached the Yuan Infant Realm and have impacted the God Transformation Stage have encountered a small heavenly tribulation.

In fact, in the ancient cultivation era 40,000 years ago, the vast majority of cultivators were not aware of the existence of the "Great Heavenly Tribulation" at all, they only knew about one kind of Heavenly Tribulation, and that was the "Small Heavenly Tribulation" aimed at individuals!

If the Great Tribulation that destroyed the planet was an attack by another civilization, what was the Little Tribulation?

It's not necessarily that a civilization is so boring, full of food, crossing the vast galaxy, and blasting out a heavenly catastrophe to kill someone, right? ――

Today the fourth chapter is delivered!

One thing to declare for the record.

Although many book friends have seen it, there must be many book friends who may not know that the "dark forest" theory and the "chain of suspicion" are not original to Lao Niu, but the concepts proposed by Liu Cixin, a science fiction writer whom Lao Niu admires very much, in the "Three-Body Problem" trilogy.

It is used here to express Lao Niu's reverence for Teacher Liu Cixin, and please know it.

The magnificent sea of stars has finally unfolded, and the battle after that will be even more exciting, I hope you will continue to support it! (To be continued.) )
