Chen Xin raised his head forty-five degrees and looked up at the starry sky, if this posture was made on the earth, he would have to be scolded for pretending to be forced to be struck by lightning, but at this time, when he made this posture, a senior master's demeanor came to his face.

Elf Princess Leah glanced at Chen Xin secretly, and quickly lowered her head, feeling uneasy in her heart, like a criminal waiting for the judge to judge.

"500 million years!"

Chen Xin sighed, and exchanged speed with the steel hammer in his mind.

……

"Steel, are you sure that ancient humans are only more than 50 million years old?"

"yes, old bean, what's wrong?"

Chen Xindao: "I have already obtained the Taiji diagram from that chick of the Tianqin civilization, and the other party said that she found it from a three-pole civilization spaceship that is at least 500 million years old. ”

"500 million years of history?" Gang Yi suddenly exclaimed, and soon, he was silent again, and after a long time, he said: "Old Dou, you act according to the plan first, and then I will think about it carefully." ”

Chen Xin can understand the shock of the steel hammer.

If the Taiji diagram is really as this elven chick said, then it makes sense why ancient humans were able to become advanced civilizations on earth in just a few million years.

Maybe after the extinction of the dinosaurs, everything that happened on the earth was an illusion released by them, and in fact they had been developing for at least hundreds of millions of years.

As for what they have developed, why did they appear in the solar system after the dinosaurs disappeared, why did they hide the solar system, and why did they put a taiji diagram in the hands of the steel hammer?

There are no answers to these questions, and there are still too many mysteries hidden in them that need to be solved by Chen Xin and Gangyi.

……

Inside the spaceship.

Chen Xin was silent for a long time before he said slowly: "I really didn't expect that I would be lucky enough to see the second Taiji diagram in this life." Princess Leah, since you brought this thing into the solar system, it means that you are related to our race, so let's do it, within my ability, I can grant you a request. ”

Leah's delicate body couldn't help but tremble, and she looked at Chen Xin in surprise and said, "Big ...... What do you say, my lord?"

Chen Xin said lightly: "Don't call me an adult, let's call me senior, you can make a request to me within my ability, and I will do my best to satisfy you!"

"Big ...... Oh no, senior, are you telling the truth?"

"The Strategic Fool Bureau never tells lies!" Chen Xin said awe-inspiringly.

Click-

The elven princess Leah fell to her knees and sobbed: "Senior, please save our fellow Terran compatriots for the sake of the same Terrans!"

"Please, please save your fellow Terrans!"

The vassal races behind Leah also fell to their knees in unison, pleading.

"Save you, what do you say?" Chen Xin still looked detached.

The elven princess Leah burst into tears, and I saw pity and said, "Senior, we Terrans...... We Terrans ......"

In Princess Leia's crying accusations, after she disappeared the solar system, how did the carbon-based life alliance use the human race as an experimental object, wantonly squeezing the human civilization, how to station the human civilization to the border of the silicon-based alliance, and became the cannon fodder for the confrontation between the two alliances, and they even made a hybrid product between the human race and creatures of different races, it is said that a beautiful mermaid slave has a price within the entire carbon-based life alliance.

In the end, Princess Leah cried loudly: "Senior, even a race like our Lyra civilization that has reached the peak of the fifth level needs to pay 100 million clansmen to the alliance every year to survive, and our army is also deployed on the front line of the confrontation with the silicon-based civilization, becoming the sharpest knife in their hands, in front of the alliance, our human race has no dignity at all, and can only be reduced to cannon fodder and experimental products of those advanced civilizations......"

Chen Xin looked at his whole body lying on the ground, silent.

He didn't know that according to the tradition of the Tianqin civilization, when Princess Leah made such a gesture, it already represented her absolute submission to Chen Xin, and Chen Xin had the right to ask Princess Leah to do anything at this time.

It's a pity that Chen Xin doesn't know.

Chen Xindao: "You get up first!"

"Senpai!"

"Listen to me and get up!"

"Yes, Senpai!"

Princess Leah raised her head, her eyes were red, and her beautiful big eyes looked at Chen Xin pitifully.

Chen Xindao: "The carbon-based life alliance you are talking about, but what those little miscellaneous fish made up?"

"Little trash fish?"

Princess Leah was slightly stunned, then covered her mouth with her hand and stammered, "You...... The little trash fish you are talking about is a flying fish civilization?"

Chen Xindao: "Who else can there be if it's not those guys?!"

Among the three seventh-level civilizations of the Carbon-Based Life Alliance, the Flying Fish Civilization ranks first in terms of strength, which is what the steel hammer told him.

Princess Leah had completely lost her voice by this time!

That's the dignified Flying Fish civilization, the absolute overlord of the entire Virgo Supercluster, the supreme being in the carbon-based life alliance, and has become a small miscellaneous fish in his mouth?

Princess Leah said: "My lord, at present, there are three seventh-level civilizations in the carbon-based alliance, which are the Flying Fish Civilization, the Rachet Civilization and the Spore Civilization. ”

Chen Xindao: "What about the Silicon-based Life Alliance?"

Princess Leah said, "There are only two seventh-level civilizations in the Silicon-based Life Alliance, which are the Amethyst Civilization and the Flame Civilization. ”

Chen Xin sighed: "I really didn't expect that carbon-based life and those stone people would develop to this kind of course, I'm sorry, for some reasons, I can't help you go to the Flying Kite Galaxy to destroy that group of miscellaneous fish for the time being, you still have to make some other requests, for example, I can help you break through the civilization level from level five to level six." ”

"What...... What?"

Princess Leah was stunned.

When Chen Xin said that he couldn't help her for the time being, her face turned snow-white, but when she heard that Chen Xin could help her raise the level of the Tianqin civilization from level five to level six, Princess Leah's little head suddenly crashed!

What did she do when she ventured into the Lost Star Domain this time?

Isn't it just to find an opportunity for a breakthrough in civilization?

Who would have thought that Chen Xin's fluttering words would solve the biggest problem faced by the Tianqin civilization.

Compared with breaking through to the sixth-level civilization, even if the Flying Fish civilization is destroyed, no matter which civilization it is, only the growth of its own strength is the most important, and the others are all empty.

Isn't there a saying that is good?

In the universe, no matter how fast you run, there will always be someone faster than you, and no matter how slow you run, there will always be someone slower than you.

In the vastness of the universe, you never know how many miracles are hidden.

Princess Leah hurriedly wiped away her tears, and said with a bright smile: "Senior, then please...... Please tell me how our Lyra civilization can break through from level 5 to level 6......"

Princess Leah stared at Chen Xin with unblinking eyes, her ears pricked up, as if she wanted to keep everything Chen Xin said in her heart.

Chen Xin looked at Princess Leah, who had an urgent face, and secretly sighed in his heart, it seems that the survival of human civilization in the universe is really difficult!

A civilization, from the first level to the highest level of science and technology, will only involve more and more scientific categories, and the scientific research resources required will also show an exponential increase.

Especially after breaking through to the three-pole civilization, how to choose the right technology tree has become the biggest difficulty for all civilizations that want to upgrade.

For example, if a three-pole civilization wants to upgrade to level four, then it must get rid of the limitation of the speed of light.

But how do you do faster-than-light?

Tachyon technology (tachyon, negative mass particles, the lowest speed is the speed of light), wormhole theory, and grand unified field theory are all possible to achieve faster than the speed of light, but in these three technologies, only the curvature engine established according to the grand unified field theory can achieve superluminal speed flight within the scientific and technological scope of the tripolar civilization, and the establishment of the grand unified field theory will further promote the development of material technology, computer technology and even biotechnology.

If you, as the leader of the three-pole civilization, choose the wrong technology tree and invest a lot of scientific research resources in tachyon technology and wormhole theory, then congratulations, you may have to go through tens of thousands of years before you may know that you have embarked on a wrong path, and all of them will have to start all over again.

Therefore, in a certain sense, the development of science and technology is a process of stepping on mines, and only by constantly stepping on mines can you find a correct way forward.

Then from level four to level five, from level five to level six.

In the universe, the technological blockade between different levels of civilization is extremely tight, if it is possible to obtain the path of civilization through other means below level 5, then after level 5, it is almost impossible to succeed by relying entirely on yourself!

Level 5 civilizations have developed to the point where they can use positive and antimatter to annihilate energy and fly at a hundred times the speed of light.

By this time, there was almost nothing in the galaxy that could hinder the exploration of the fifth-level civilizations, and their research on microscopic matter and macrocosm was also more in-depth.

There will be millions of disciplines involved in their research, and it will be almost impossible to choose the right path from so many disciplines in a short period of time.

The Tianqin civilization has been at the peak of the fifth level for nearly 100,000 years, and it has never found a correct path, which is why the leadership of the Tianqin civilization is so urgent. R1152
