Gangyi hurriedly denied it: "Old bean, I'm ...... I swear, I really didn't lie to you!"

Chen Xin did not speak.

"Well, if I lie to you, you'll punish me for a year—oh no, half a year of gold!"

Chen Xin rolled his eyes, and slandered in his heart, the character of this guy is becoming more and more like a human.

But when it comes to lying, it is still very immature, Chen Xin immediately heard the weakness in its tone, and sneered: "Gangyi, do you know how long the history of the earth is?"

Gangyi was faintly uneasy, didn't understand what Chen Xin meant, and replied: "Forty-four billion years!"

Chen Xin said again: "What about life history?"

"Thirty-eight billion years!"

Chen Xin sighed: "Yes, 3.8 billion years of long history! I remember you once said that in the galaxy, there are more than 10,000 intelligent civilizations above the third level, and according to the pyramid principle, there are at least tens of millions of planets below the third level zero (primitive life planets without intelligent civilizations), first-level and second-level civilization planets, right?" The Milky Way galaxy is 100,000 light-years in diameter, the number of stars is close to 200 billion, and there is only one life planet in an average of 20,000 star systems, so if you calculate it, life planets should be very sought-after for those high-level carbon-based civilizations, but why has the earth civilization developed for so many years, except for you and the Karn civilization, why has there never been a trace of alien civilization on the earth?"

@陈新这个问题问得非常关键, in any case, with the technology of a fifth-level civilization, it is fully capable of making a specific count of the living planets in the galaxy, and it is simply impossible for the earth to miss the past.

Not to mention the significance of such a huge species gene on Earth for an advanced carbon-based civilization.

The steel hammer was silent.

Chen Xin didn't speak.

After a long while, Gangyi let out a long sigh of relief and said, "Lao Dou, there are some things, I originally wanted to sue you in a few years, but since I have said it today." Then I'll tell you all about it!"

Chen Xin smiled slightly and said, "You say." ”

"Old Bean, do you know why I am on Earth, and why we have formed such a strange relationship?"

Chen Xin shook his head and said, "I don't know." ”

He also had a lot of speculations about these two questions, but he didn't know anything about it, and he didn't have a good way. But the only thing Chen Xin can be sure of is. will never betray himself, this intuition seems to be out of trust in the depths of his soul, and Chen Xin can't say why.

"We'll talk about these two questions later. Let's start with the history of the earth. Lao Dou, as you know, the current paleontological research on the earth mainly uses the carbon-14 isotope of some ancient fossils to determine the age of its life, and then infer the environment in which it lives according to geological changes. ”

Chen Xin nodded.

"Overall, this line of thinking is not wrong. Human paleontologists have also achieved a lot of results through this, but ......"

The steel hammer paused deliberately.

Chen Xin was puzzled: "But what?"

The steel hammer laughed: "But...... There are also many truths drowned in the vast river of time, and some things are completely beyond human imagination. Like an ancient behemoth?"

"Ancient Behemoths?"

"Oh, I almost forgot, humans should call them dinosaurs!"

Chen Xin frowned, with a faint hint of speculation in his heart, and asked, "What's wrong with the dinosaurs? Aren't they extinct?"

"Extermination?"

Gangyi laughed and said, "The famous giant beast civilization, mature individuals can compete with stellar-class warships. How could the only existence in the entire Virgo supercluster that is beyond the alliance of carbon-based and silicon-based life be extinct?"

Chen Xin's eyes widened suddenly. Swallowed his saliva and said: "Steel hammer, just dinosaurs, can individuals fight against stellar-class warships, beyond the carbon-based life alliance and the silicon-based life alliance?"

Gangyi seemed to hear the disbelief in Chen Xin's tone, and sneered: "Old Dou, don't compare the giant beast civilization with those low-level dinosaur fossils unearthed from the earth. The real Behemoth Civilization is a group of war Behemoths with extremely powerful individual combat power, and their lifespan is often as high as tens of millions of years, and their personalities are fierce and unruly. Back then, the Milky Way was completely their backyard. It's just that then a big thing happened. They had to hide and lick their wounds. ”

"What's the big deal?" Chen Xin was attracted by the story told by Gangyi, and hurriedly asked.

"About sixty million years ago, in the late Cretaceous period on Earth, the Behemoth Civilization clashed with a seventh-level silicon-based civilization in the Flying Ring Galaxy, three million light-years away from the Milky Way, and a large-scale war broke out between the two. The war was so long, it lasted for more than five million years, and the entire Flying Ring Galaxy was affected by the war, the silver core of the Flying Ring Galaxy was completely destroyed, more than 100 billion stars were destroyed, and both sides suffered heavy losses. The original total population of the Behemoth Civilization exceeded 100 million, and it lost four-fifths in this war, and the two billion ordinary warships of the seventh-level silicon-based civilization also disappeared in the icy void of the Flying Ring Galaxy. Both sides fought real fire, and in the end, the seventh-level silicon-based civilization decided to dispatch the neutron battle star at the bottom of the box to solve the threat of the giant beast civilization in one fell swoop, and the giant beast civilization did not show weakness! Not only ruthless to the enemy, but also ruthless to themselves, in order to deal with the neutron war stars of the seventh-level civilization, they dispatched the last 20,000 war monsters that can compete with stellar warships, and launched a suicide attack on the neutron battle stars, each of these war beasts is comparable to Jupiter, do you imagine, what will happen when 20,000 Jupiters merge with neutron stars?"

Chen Xin swallowed his saliva, the magnificent scene had completely exceeded his expectations, and he asked tentatively, "Supernova explosion?"

"Twenty thousand Jupiters are equivalent to twenty times the mass of the Sun, and they are constantly fused by neutron stars, and the superimposed masses are getting bigger and bigger. Finally, the neutron star's own gravity far exceeds the critical pressure of the neutron star, and at this moment, the neutrons inside the neutron star can no longer withstand the huge gravity, and directly collapses into quarks, which continue to collapse towards the singularity, forming a super-large black hole, a large amount of matter, The gamma-ray explosion exploded at this moment, and the remaining material in the core of the flying ring galaxy was swept away by the energy of the supernova explosion, and since then, the flying ring galaxy has become a real flying ring, and some human astronomers call it the ring galaxy (Hastelloy galaxy, discovered by astronomer Artehuo in the 50s of the 20th century). ”

Chen Xin was dumbfounded when he heard this, and asked, "What about later?"

The steel hammer quacked and laughed, "Later...... Later, without the Neutron Battle Star, this silicon-based civilization was jointly annexed by the other two seventh-level civilizations of the Silicon-based Life Alliance, and it was precisely because of this that I was co-opted by them and became a guest secretary of the Silicon-based Life Alliance. As for the giant beast civilization, no one knows where they went, and in order to force them out, the two seventh-level civilizations even teamed up to direct the mass extinction of earth life at the end of the Cretaceous period, when a huge asteroid crashed into the seabed near the Yucatan Peninsula in Mexico, and the earth life was completely cleansed. Unfortunately, these behemoths never showed up, and to this day, no one knows where they went. (To be continued......) R1292
