After laughing for a long time, Chu Tianjiang stopped.

The girl looked at him indifferently, not surprised or surprised.

"I know that you can read my mind directly." Chu Tianjiang suppressed his laughter, "Although I can't read your thoughts, I can guess. ”

"Guess?"

"Something to preserve my consciousness and wake me up from my dreams."

"Really?"

"You didn't create the micro-universe where the solar system is located for no reason, and you didn't help mankind without asking for anything in return, you have a more important purpose." Chu Tianjiang raised his hand and pointed at the girl. "You have to use human beings, let human beings be the carriers of your thoughts, so that you can exist in three-dimensional space."

The girl laughed. "You're right, but it's not complete."

Chu Tianjiang looked at the girl expressionlessly. This is not his guess, but a guess made by Luo Jinyong. Now it seems that Luo Jinyong's guess is not wrong.

"For us, creating a microverse is as easy as building a castle out of sand on the beach. Theoretically, any one of us can create an infinite number of micro-universes in three-dimensional space, but due to resource limitations, not all individuals can create micro-universes, nor can they create micro-universes without limits. The girl smiled faintly and said, "Strictly speaking, I'm not a qualified engineer. ”

"Engineer!?"

"In your words, in the beginning, the creation of a three-dimensional microuniverse was just a scientific research project. If human beings master the relevant techniques, they will definitely expand into two-dimensional space and start similar scientific research plans. The girl paused slightly. As a participant in this research project, I was responsible for creating the microuniverse in which the solar system is located. Because I don't know much about three-dimensional space, this micro-universe is not stable. ”

Chu Tianjiang frowned, the intelligent individual of this great civilization turned out to be a scientist.

"I created a star that collapsed very quickly because it was so massive that it existed for an extremely short period of time. By your time, it's less than 10 million years. After the star collapsed, instead of forming a black hole, it exploded again and became a supernova. ”

"And then?"

"Although some of the material was thrown away during the supernova Big Bang, the mass of the star is still too large after rebirth. The star has existed for nearly a billion years and has also generated dozens of planets and many more asteroids, moons, comets and other natural objects. Unfortunately, the temperature of the stars is too high, and the planets that are generated are too large to provide an environment for life to thrive. Life appeared on the moon of only one large planet. It's just that the star's existence is still too short to evolve intelligent life. After burning most of the matter, the star collapsed again and was reborn after the second Big Bang. ”

"The sun?"

The girl nodded. "Now this star is already the third, to be precise, the third life cycle of the same star, and the last. After the Second Big Bang, a large amount of matter was thrown into outer space, and the second combustion, which lasted for a billion years, converted a large amount of mass into energy, enhancing the dynamic equilibrium of the microuniverse and laying the foundation for the creation of planets where life could thrive. The star has a life cycle of about 10 billion years and can provide enough heat for the Earth to maintain its ecological environment for about 4 billion years in the middle of its life. In other words, the Earth's ecological environment will exist for about two billion years. ”

"And then?"

"The star will collapse into a white dwarf and acquire a stable structure, and the Big Bang will no longer occur, and the entire microuniverse will die from it." The girl smiled faintly and said, "When designing, you have to leave a margin." Not to mention two billion years, even if we give human beings a few hundred years, at most a thousand years, we can break through the minimum threshold, and the solar system is no longer the only home of human beings, and the survival of the sun has nothing to do with human beings. ”

Chu Tianjiang sighed secretly, this is the truth.

"Of course, human beings are not the first intelligent life in this micro-universe, and the earth is not the first home of life."

"Mars?"

The girl nodded and said: "About three billion years ago, that is, one billion years after the formation of the current solar system, the sun was much more blazing than now, and the 'ecosphere' suitable for the existence of carbon-based life was between the orbit of Mars and the asteroid belt, and the earth at that time was a hot planet, which was not suitable for life at all. Life on Mars existed for about 500 million years, and the first intelligent life evolved, a more advanced intelligent life than humans. Unfortunately, at that time, it was only a trial project, and there was no dimensionality reduction involved. ”

"Test the project?"

"To put it simply, life on Mars was created directly by me, not by natural evolution. Although I was hoping that the trial would be a success, it backfired. The girl sighed as she learned from Chu Tianjiang. The speed of evolution of this intelligent life is too fast, and the speed of technological progress is particularly amazing, and it soon entered the stage of self-evolution and mastered some very advanced technology. The problem is that at that time, the dimensionality reduction had not yet begun, and the three-dimensional micro-universe only existed in the experiment, and it was all closely protected, even if this civilization mastered the technique of breaking through the micro-universe, it could not colonize other micro-universes. As Mars' resources were depleted, the civilization began to migrate to neighboring planets. Not the Earth, but the planet that is located on the outer side of the orbit of Mars. ”

"Planets?"

"The asteroid belt now." The girl explained briefly. "It's a planet that's slightly smaller than Mars, with a lot of liquid water. Because it is in the zone of life, life has also been born on this planet, and it is naturally formed. Because it has not been disturbed, life on this planet has evolved very slowly, and intelligent life has not yet been produced, so it cannot fight against the powerful Martian civilization. ”

"Extinct?"

The girl nodded, and said, "It's just that the Martian civilization has not survived. Because the distribution of resources between the colonies and the mainland is extremely uneven, most Martians still remain on Mars, but the resources are concentrated in the colonies, so soon after, the Martian civilization broke out into a civil war. A protracted war that consumes the worst resources on Mars and leads to the destruction of the colony planet in the Big Bang. ”

"The asteroid belt was created from this?"

"And a lot of comets."

Chu Tianjiang understood, the resources that the girl was talking about obviously meant liquid water.

"The demise of the Martian civilization proves that our intervention did not contribute to the evolution of life in the microuniverse. It also proves a problem that we have ignored before, that is, the progress of civilization is gradual, without sufficient understanding, and the more advanced the technology mastered, the more dangerous it is. ”

"And then?"

"As the sun emitted a lot of energy at the beginning of its life, the temperature began to decrease, and the life belt contracted, and the earth entered the life belt, and gradually formed a natural environment for life to exist."

"Wait!"

The girl stopped, looked at Chu Tianjiang, and said, "You're not mistaken, this is indeed related to me." In the early days, the Earth was actually a planet with no water at all. Because Mars has deviated from the life zone, I have to create a planet where life can exist. ”

"You brought the water from that planet to Earth?"

The girl nodded and said, "To be precise, it was the comet that was generated after the explosion of the planet that was lured to the earth and brought water to the earth. What I didn't expect was that the comet also brought the seeds of life to Earth. It's a purely natural life that has nothing to do with me. In the beginning, it was just a single-celled life. Hundreds of millions of years later, multicellular life evolved, then higher plants and higher animals, and finally humans. In the more than two billion years of life history of the earth, human beings were not the first intelligent life. ”

"Before?"

"The first type of intelligent life, which appeared about 400 million years ago, was an aquatic life with a very low level of intelligence and did not meet the minimum requirements. A volcanic eruption that lasted for 500 years completely changed the marine environment at the time and led to the extinction of this undeveloped concept. ”

"You ......"

"The second type of intelligent life appeared about 200 million years ago and is a reptile. Although the intelligence level is not low, the adaptability is very poor, the temperature of the living environment is very high, and the evolution speed is too slow. A gamma-ray burst created by me exposed the entire earth to gamma rays, and the atmospheric environment changed dramatically, destroying the environment suitable for this kind of life. ”

"Causing its extinction?"

The girl nodded. "The third intelligent life appeared 100 million years ago, and it is the dinosaurs you are familiar with, one of them to be exact. This intelligent dinosaur is similar to you, and it is a homeothermic animal, able to adapt to various environments, and has a high level of intelligence. It can be said that this is almost a perfect intelligent life, but it is a pity that there are serious self-destructive tendencies and the sociality is not very strong. ”

"You're going to hit the Earth with an asteroid and wipe it out?"

"It also destroyed traces of its civilization."

"What?"

"At the time of destruction, this intelligent life had just entered the era of industrial civilization, and the impact point of the asteroid was the civilization center of this intelligent life. The high-temperature air currents generated by the impact swept across the globe, destroying traces of civilization in various parts of the world where this intelligent life existed. ”

"You ......"

"In other words, human beings are the fourth intelligent life on Earth, but it is likely to be the last."

"What do you mean?"

"You have failed, and it is not only the opportunity to evolve that you have lost, but also your homeland."

"Nope! No—" Chu Tianjiang stared at the girl. "I'm alive, humanity isn't extinct, we're not failing, and we're not going to give up."

"What can you do?"

"What can you let me do!?"
