In his sight, his mining vehicle was still collecting resources back and forth in the distance, and he smiled and took the elevator to the first biosphere, and after a while he arrived at the underground test base.

"Alicia, I've brought back the test specimens, I'm already locked in the test cage, hurry up and go with me to take a look."

In the laboratory, Yu Nan greeted Alicia directly, Alicia raised her head to look at Yu Nan, she happily ran to Yu Nan and said:

"Why did you come back after only a few days of going this time, what kind of test did you say?"

Yu Nan laughed, pretended to point to the outside mysteriously, and said:

"Let's go and have a look, won't you?"

Alicia jumped with Yu Nan to the huge test cage area specially built by Yu Nan, this time Alicia's mouth opened wide, and after half a ring, she looked at Yu Nan sluggishly and said:

"Dinosaurs...... Where did you find this extinct creature? ”

There are dozens of cages here, and the dinosaurs in them are all carnivorous dinosaurs, and they are powerful existences from the Triassic to the end of the Jurassic period, but at this time they are locked in by Yu Nan, Alicia knows that Yu Nan has a lot of ability, but she never thought that Yu Nan would catch so many things that should have disappeared.

Yu Nan shook his head and said:

"Alicia, there are some things I'll tell you later, but for now you should use them for experiments, now in addition to the surrounding area, I also have to set up a dinosaur ecosystem, I guess I have to work here for a while."

Alicia actually nodded very obediently, she arranged for Alice clones to deal with the dinosaurs here, so many big guys, although it is very suitable for experiments, but it is troublesome to feed.

However, Yu Nan still has a way, he has a lot of plant-eating dinosaurs in his hands, he plans to build a dinosaur ecosystem as soon as possible, with ancient vegetation can make plant-eating dinosaurs grow, with plant-eating dinosaurs, starvation and carnivorous dinosaurs, so that the ecosystem can also be maintained, now he can take out some plant-eating dinosaurs as food feeding test subjects.

In the next year, Yu Nan began his large-scale ecological circle construction at the moon base, and at the same time began to rebuild a spaceship according to various scientific and technological technologies, this spaceship has the stealth function of an iron-blooded spaceship, and also has the super engine propulsion and defense capabilities of the Three-Eyed Clan, and also added compressed space and anti-gravity technology, with not high-level energy weapons and physical weapons, the power of the super-large weapon system made in the compressed space is still very powerful.

"Roar...... Whew......"

In an ecosphere that simulates the gravity of the earth, at temperatures above 40 degrees Celsius, a variety of ancient vegetation grows lush on several hundreds of square kilometers of ground, artificial rivers merge into artificial lakes and artificial oceans, and the simulated ocean currents and air flows are connected to other biospheres.

A huge ecosphere group was formed under the moon, countless animals and plants grew normally in a controlled environment, looking at those wild dinosaurs, Yu Nan admired with satisfaction with a smile in a connected observation window, this is his first moon base, and his first attempt, although it doesn't look perfect, but it's not bad.

"Yu Nan, come to the lab."

Alicia's voice came from the intercom in the corner, Yu Nan closed the observation window and took the automatic conveyor to the laboratory after a while, in the laboratory, Alicia beckoned to him happily and said:

"Quick, come here, I've found a fatal flaw in the second human gene you gave me."

The second human gene, that is, the sample of the beauty of the Three-Eyed Clan, Yu Nan found that the beauty of the Three-Eyed Clan was actually the same as the human gene, but he couldn't understand why this powerful human race was scared by a disease and fled the earth.

"What is the fatal flaw?" Yu Nan asked.

Alicia quickly projected a set of genetic images, and she pointed to the gene strand on it and said:

"This gene is indeed very perfect in other aspects, but some of the antibodies that this gene can produce are much stronger than the antibodies that we normally have, and it seems that it is precisely because of this person's innate genes that it is very perfect, and it can resist many internal diseases, such as cancer and other diseases, but there is a problem with the common cold virus;

Because this gene is very powerful, the initial virus does not affect their health at all, and their bodies will only produce antibodies when the virus outbreak is affected, so that their body structure is not able to resist during the outbreak, that is, by the time the antibodies in their cells are produced, the virus has completely infected all cells. ”

Yu Nan nodded understandingly, that is to say, the Three-Eyed Clan can ignore the internal functional diseases of human beings such as cancer, and even powerful viruses will not be affected, but will form functional defects to the weak viruses on the outside, and by the time their body antibodies are produced, the speed can no longer keep up with the outbreak effect of the virus.

It's all because their own physical fitness is very strong, and it's too late for the body to sense the impact of the virus and produce antibodies, perhaps this is also the reason why the Three-Eyed Clan disappeared.

"Is there a way to change this genetic defect?" Yu Nan asked.

Alicia shook her head and said:

"I don't know for the time being, but I'll continue to do experiments, by the way, your genetic structure is too stable, the genetic sequences of dinosaurs can't withstand it, as long as you do cross-testing, there will definitely be mutations, it seems that you have to find more advanced and powerful creatures."

Stronger, Yu Nan remembered the fire unicorn and the true dragon in the wind and cloud world, these two creatures are powerful enough, but the samples in his hand have tried to clone dozens of times without success, and the genes of the fire unicorn and the real dragon are also very strong, and the difficulty of gene cloning is about the same as his genetic cross test.

Yu Nan says:

"Hmm...... Let's continue the experiment, the ecosystem here has been established, and the satellite network of the Earth and the Moon has been arranged, if you are bored here, you can take a shuttle to the Earth to go around, and tomorrow I have to leave again, and next time I will bring you some strange and powerful creatures to experiment. ”

Alicia just nodded, looking at Yu Nan who turned to leave, Alicia touched her smooth baby-like face after using Yu Nan's serum and whispered to herself:

"This wooden man, here I and the Alice clones have other pursuits, if he wants, we can all be his women, maybe we can give birth to hundreds of children, and then go to the earth to get some people here, and the moon can develop independently."

To be honest, Yu Nan really didn't think about sleeping with Alicia and Alice clones, because in his eyes, Alicia and the clones looked exactly the same, although they looked quite beautiful, a large group of the same girls dangled in front of them, and a man couldn't be interested.

Leaving Alicia's laboratory, Yu Nan didn't even leave the ecosystem this time, and after arriving at his lounge, he directly turned back to the real world and returned to Qin Ke, and found that Qin Ke had returned to Shangdu City and started to work normally, so Yu Nan planned to continue to travel through other worlds.
