The star was hit by a particle of light, and a cavity with a diameter of 50,000 kilometers was cracked in the middle, which could put four Earth's cavities, and this cavity was facing the planet of the Trisolaran.

The cavity then erupted with a stream of particles, and the high-temperature plasma stream, after four hours of eruption, arrived at the three-body planet, before that, only a small number of three-body people fled in spaceships.

The planet was burned into a large red ball. Then the fusion reaction inside the star weakens and rapidly dims, and the star begins to collapse, squeezing the inner core, triggering a big bang that covers the remaining two stars.

These two stars can form a stable system, and the red-hot three-body planet will be attracted by gravity, fall into this star, and disappear.

"How many of you escaped?" Cheng Xin asked softly,

"Including the previous expeditionary fleet, it is less than one thousandth in total!" Tomoko was still boiling her tea.

"How long are we left?" Cheng Xin asked again, this is the focus of all human beings.

"It's not certain yet, the blow will come at any time, maybe a year later, maybe a century or two, just like you experimented with before!" Zhizi glanced at Luo Ji and said, but Luo Ji was silent.

"You know, the situation of the three-body world is different from that of the solar system, the first thing that is broadcast is the coordinates of the three-body galaxy, if you want to detect the civilization of the earth, then you have to look through the materials of previous centuries of communication, which will take time!

Moreover, the three-body galaxy is composed of three stars, which is relatively unique in the universe, while the solar system is just an ordinary star, which is relatively less dangerous! Tomoko said.

Cheng thought for a moment and said: "The two previous blows were both light particles destroying stars, is this a relatively common way to strike in the universe?" Will the same be true for future strikes on the solar system? Do you use light particles? ”

Zhizi said: "The Dark Forest Strike has two characteristics, the first is arbitrary, and the second is economic, so the destruction of the earth is probably just a possible threat that other civilizations can easily destroy!"

The coordinates of the three-body galaxy are released, and the only blow is a particle of light, and they will not conduct a close probe of the target to see if there is a civilization on the planet and whether there are resources.

The so-called economy is to strike at the lowest cost, trigger the destructive energy in the star, destroy the star, then its planet will be destroyed naturally! ”

"So, can we defend against light particles?" Cheng Xin asked.

Tomoko shook her head and said, "Blows can come from any direction, and for the entire universe, we are like birds on the top of a tree illuminated by lights, and we can't be sure where there will be a shotgun." However, judging from the striking nature of the light particles, there is a possibility of defense! ”

"In your three-body world, didn't anyone survive this stellar explosion? Can we learn from that? Cheng Xin asked.

"That's our spaceship can reach the speed of light, believe me, humans don't have this ability, you better run away, this is the best way!" Tomoko said.

"But escape, our stellar spaceship is estimated to not be able to save even 10,000 humans!" Cheng Xin sighed.

"That's better than annihilation!" Tomoko said calmly.

Survival is instinct, and individual survival is the most fundamental desire, but in the case of human beings on earth, their civilization cannot make them give up their lives. cruel

Whether more or less, humans today have evolved this high degree of self-awareness.

Cheng Xin wanted to ask again, but Zhizi interrupted her: "Please don't talk about this again, okay?" That's all I can tell you, I'm inviting you two to tea! ”

Luo Ji took the teacup and said, "Can't I ask anymore?" ”

Different from the gentleness and friendliness shown to Cheng Xin, Zhizi was full of awe for Luo Jiji, and there was a clear difference from her gaze, where Zhizi was sitting, farther away from Luo Ji than Cheng Xin, and she bowed deeper to Luo Ji.

Tomoko bowed deeply and said, "Please wait a minute! ”

Then Zhizi's eyes became blank, which was between her and the three-body head who was several light years away, and finally Zhizi said: "You can only ask one question, I can only give yes, no, or don't know, these three answers!" ”

Luo Ji drank the tea and slowly put down the cup, but Zhizi raised his hand again to stop him: "This is the respect that my world respects you, my answer must be true, even if this answer may be harmful to the three-body world, but I can only answer one question, and I can only do these three simple answers, please think carefully before asking questions!" ”

Cheng Xin looked at Luo Ji worriedly, but Luo Ji did not think about it as she imagined and thought about it for a long time, but said directly and decisively: "From a long-distance observation on a cosmic scale, the three-body world shows a certain dangerous characteristic, so is there a certain security feature, or a security statement, that can show the universe that a civilization is safe and will not be posed any threat by other worlds, and then avoid the attack of the dark forest, and human civilization has a way to issue such a security statement to the universe?" ”

For this question, Zhizi didn't answer for a long time, but in the end she suddenly looked at Luo Ji seriously, this move, she had never done it before, Zhizi's answer was only one word: "Yes!" ”

"How?" Cheng Xin hurriedly asked, Zhizi slowly took his eyes off Luo Ji, shook his head and said, "There is nothing to tell you anymore, no more!" ”

When human beings were looking for a cosmic security statement, Zhang Xuan was alone, and came to the Trimaran Fleet, looking at the Trisolaran in a daze, Zhang Xuan smiled and said: "Your fleet has become the speed of light, but it is a little difficult to find!" ”

Looking at the ship, a Taoist priest suddenly appeared, and the three-body crew members hurriedly stood guarded, and the electric gun in their hands pressed the button, and a flash of lightning directly attacked Zhang Xuan.

Zhang Xuan just frowned, and the electric light disappeared without a trace: "What are you doing here?" Just met you officially and shot directly? ”

"Alarm, there is a layer of spatial fluctuations inside the ship, and the attack of the cluster gun has been transferred to other dimensions!" Trimaran computer analysis.

Hearing the news, those crew members stopped attacking, and Zhang Xuan smiled: "That's right, I have no malicious intent, otherwise you would have died!" ”

The three-body head was wearing a heavy protective suit, approached Zhang Xuan and said, "Who are you?" How did it come about? On top of our ships? We screened all earthlings, without you! ”

Zhang Xuan said: "I am Zhang Xuan, an observer of the universe, of course, seven thousand years ago, when your planet was about to be swallowed by the sun due to the fluctuation of the nearby gravitational field, I also saved you!"

Your self-improvement, calm and wisdom, I am very happy, I came here to tell you, you are moving in the wrong direction, the universe in front of you is the battlefield of the silicon-based empire and the carbon-based alliance!

If you go in with your strength, you will only turn into dust, and their strength and technology are not something you can resist now! ”

"Was it a war in the universe? The silicon-based empire and the carbon-based alliance seem to be a large field classified by biological elements and cultures! "The head of the three-body problem said.
