Jing Zhonghua led her team back to the land in front of the magical cave entrance. With the help of Earth's spaceships and mechs, the Magical Cave Exploration Station was soon built.

According to the Xindi Terraforming Project, the first step of the expedition was to introduce microorganisms from Earth to some of the places found on the planet Xindi that were in slightly better conditions. The first microorganisms to be introduced must be photoautotrophs. This photoautotrophic organism is characterized by its ability to use sunlight as an energy source and does not require complex organic matter in the metabolic process, thus ensuring that the organisms introduced from the terrestrial planet can survive on the new terrestrial planet and adapt to the harsh environment on the new terrestrial planet.

The Cyanobacteria brought from the Earth planet are stored in the exploration station of the flower in the view, and she wants to find a suitable pond on this new land as soon as possible to keep the blue algae alive on the Earth planet.

Jing Zhonghua is still building a station in the Magical Cave Exploration Station, she ran to the exploration station to explore around her alone, and to her surprise, there is actually a pond not far from the Magical Cave Exploration Station, and there is cyanobacteria growing on the pond, and she doesn't need to experiment anymore. In order to confirm whether the cyanobacteria on the planet Earth can survive on the new globe, she specially demarcated an area in the pond and put the cyanobacteria brought by the planet into the pond, and as a result, within a few days, the cyanobacteria on the planet not only survived, but also began to multiply. Jing Zhonghua reported the news, which really surprised the people of the earth.

After Heng Liya got the news, she immediately made a special trip to the pond to check it, and she concluded that the plan to transform the new ball into an environment suitable for human habitation would not take a thousand years, and it might only take a hundred or even decades to complete.

To this end, Heng Liya has advanced the plan to change the composition of the atmosphere of the new ball and plant plants on the new ball. In order for the environment of the planet Xindi to be habitable for humans, it must first be aerobic, so on the basis of the introduction of microorganisms, plants should be planted on the new planet. Because only plants can convert carbon dioxide from the atmosphere of the new sphere into oxygen.

As the first plants to grow on the new ball, Heng Liya considered the product of transgenic technology. It is impossible for plants to grow and develop in an environment rich in carbon dioxide and almost completely deprived of oxygen. In addition, this plant is either pollinated by itself or by the wind and cannot be pollinated by insects. Because in the absence of insects, choosing plant seeds with the genetic technology she studied for experiments is the best choice at the moment.

Heng Liya has been accompanying Jing Zhonghua to build a tent on the experimental site in front of the magical cave for the past few days. After the glass greenhouse was set up, the team members began to sow plant seeds on the newly turned land.

In the glass house, when the flowers in the scene were planting seeds, she said to Heng Liya beside her:

"Professor Heng, I heard that you have also entered the Magical Cave, and the environment in there is really desirable."

Heng Liya threw a seed into the pit that had been dug, buried the soil, straightened up, and said:

"yes, it would be nice if the environment of the new ball could be the same as in the magic hole."

"Don't you think it's strange?" Jing Zhonghua said, "The magic cave is like a pair of invisible hands protecting it, and it is difficult for us to enter it." ”

After burying another seed with a hoe, Heng Liya said:

"It's not surprising that the entire universe is designed by God, it's a virtual world, and the doors of each virtual space are open, but we don't have the ability or discernment to find the doors that can enter these spaces."

Jing Zhonghua felt that Professor Heng had a point, nodded and said, "Yes, you are right. I feel like if I find the right door, I can get in. We entered the Arctic base, the desert ruins, and the magical caves, and it was like someone was leading us to those places with ease. However, it is even more difficult to re-enter now than to ascend to the sky. ”

Heng Liya smiled and said, "If you re-enter, I'm afraid your body won't be able to adapt." ”

Jing Zhonghua raised her head and asked suspiciously, "Why?" ”

Heng Liya stopped what she was doing and replied, "Because it is a high-dimensional space, your body has not yet mutated enough to adapt to the environment there. ”

Jing Zhonghua asked incomprehensibly: "I already have superpowers, why can't I do it yet?" ”

Heng Liya told her: "Because you are a mortal in the flesh, the human beings in the high-dimensional space have become superhuman beings, they are a kind of superhuman beings that we can never understand, they live on the other side of the cosmic wall, their environment we can't understand at all, they come and go in the universe without a trace, maybe now they are watching us by our side, but we can never see them, to explain with my understanding, they belong to the same category as dark matter and dark energy, they are dark humans." We humans call them God or God. ”

Jing Zhonghua stood up and continued to ask, "What is the Cosmic Wall, have you ever been to the other side of the Cosmic Wall?" ”

"I'm not afraid of your jokes," Heng Liya replied, "I haven't even touched the cosmic wall, and I'm already unconscious in the space tunnel, and if no one saves us, we may be trapped in that space tunnel forever." ”

After the members of the expedition had finished sowing the seeds in the glass house, they all returned to their living cabins to prepare for lunch. Jing Zhonghua came out of the glass house and came to the magical cave entrance again, and today she found that the cave entrance had been completely closed and became a mountain wall, and she could no longer find where the cave entrance was.

Heng Liya followed behind and asked, "Do you miss your little friend?" ”

"Well, it's a pity that there is no hole in the cave now." Jing Zhonghua replied disappointedly, "I would love to go in and see how they live." ”

Heng Liya took Jing Zhonghua's hand and said, "Let's go, these little guys are very smart, or they wouldn't have surrounded them in a magical cave if they didn't go to heaven, creating a special space for them." ”

Jing Zhonghua suddenly asked curiously: "According to what you say, we are also pets fenced by the heavens for experiments?" ”

Heng Liya smiled and asked, "What do you say?" ”

Jing Zhonghua thought for a moment and said, "I passed the last wonderful experience...... I think so. I don't care if it's a pet or not, I just have fun living my day. ”

"Well said!" Heng Liya nodded in approval, and she took Jing Zhonghua's hand and returned to the living cabin together.

After lunch, Heng Liya did not rest, she went directly to the experimental cabin to check the experimental animals and insects raised in the cabin. In the experimental cabin, there are monkeys, mice, cats, dogs and other animals, snakes, turtles, lizards and reptiles, as well as beetles, ladybugs, earthworms, flies, mosquitoes and other insects, etc., as well as the most common small fish on the planet, although the varieties and quantities are not much, but it is difficult to raise these animals.

Heng Liya walked into the experimental cabin and saw that Xiao Wang, a member of the expedition, was feeding the monkeys. He noticed Heng Liya coming in and said:

"Professor Heng, these animal varieties you brought are too miscellaneous and difficult to manage, especially flies and mosquitoes, they like rotten things, and it is not easy to cultivate rotten things in this experimental cabin. I can only let them suck the fragrant, sweet, fishy things......"

As she was talking, Jing Zhonghua came in from outside the cabin, she was holding a chicken leg in her hand, and when she saw Heng Liya and the breeder in the cabin, she asked with a smile:

"Did you have lunch?"

Professor Heng and Xiao Wang replied almost at the same time: "I did." ”

Xiao Wang saw Jing Zhonghua holding the chicken leg in his hand and said, "Captain Jing, you save the chicken leg and give it to Xiaohua to eat, be careful of your body." ”

Jing Zhonghua walked to the dog's cage, opened the cage, called "Xiaohua" in her mouth, and handed the chicken leg in her hand into the cage. Xiaohua happily wagged her tail when she saw the flowers in the scenery and nibbled on the chicken legs sent into the cage.

Xiao Wang saw that Jing Zhonghua liked Xiaohua so much, and said, "Captain Jing, seeing that you like Xiaohua so much, you might as well take it back and raise it in your living cabin." ”

Professor Heng waved his hand and said, "No, animals cannot be arranged into the living cabin, if humans are infected with germs on animals, it will be very difficult to treat them under the existing conditions." We wait until the conditions are ripe and then move the animals to the outside environment. The fact that I brought so many animals from the planet Earth and put them here for your experiments has already made the original plan very advanced. ”

After Jing Zhonghua watched Xiaohua finish eating the chicken legs, she held Xiaohua in her arms and stroked it.

Professor Heng came to the fish tank and asked Xiao Wang, "Why are there so many fewer fish in the fish tank?" ”

Xiao Wang snorted: "Well, fish...... I'm ...... to death."

Professor Heng felt wrong: "They were fine yesterday, why did they suddenly die today?" Where are the dead fish? I'm going to test the cause of the fish's death. ”

Xiao Wang lowered his head and stopped talking.

Jing Zhonghua told Professor Heng: "I put some fish in the pond yesterday to raise them. ”

"What?" Professor Heng couldn't believe her ears, "You put the fish in the pond to raise them?" ”

"I think that all the blue-green algae in the pond can survive, and the fish will definitely survive. ”

Professor Heng couldn't help but say, "You're just messing around, how can fish live without microbes in the pond?" With that, she hurried out of the chamber and toward the pond.

Jing Zhonghua hurriedly put Xiaohua into the cage and followed Professor Heng to the edge of the pond. They found no dead fish floating in the pond.

Professor Heng used his hands to cut away the blue-green algae floating on the surface of the water, and saw that the bottom of the water was very clear, but he never found any fish in the water. She felt very strange and thought: "Where did the fish in the pond run away? 】

In order to find the missing fish, Jing Zhonghua called Bao Dongxing, a member of the expedition team, with a hand circle, and quickly brought the fishing gear to the pond. Bao Dongxing came with a few team members, everyone fished up almost all the blue-green algae, the pond without cyanobacteria appeared more clear and transparent, everyone around the pond, squatting in different places for a long time, but never found any trace of fish. However, Professor Heng was careful, and she discovered a secret in the center of the pond. It turns out that there is a small spring in the center of this pond, and the spring water is slowly bubbling into the pond. She found that the spring water here was very special, and instructed Bao Dongxing to fill a bottle of spring water and take it back to the expedition station for testing.

Professor Heng was in the laboratory of the expedition station, and found that there were microorganisms in the spring water under the microscope, which made her overjoyed, she had been confused by this complex planet, in such a harsh environment as the new globe, there were microorganisms in the pond, and the water quality actually reached the standard of human life on the terrestrial planet, she suspected that the spring in this pond must lead to other places, which caused the water in the pond to be different, that is, this spring, so that the water in the pond will never dry up. So she asked the expedition team to use all the water from the pond to water the seeds in the glass house.

It didn't take long for all the seeds sown in the glass house to sprout and grow green leaves, and the expedition members looked at the green plants and their hearts were full of joy.

Professor Heng said to everyone: "This is our hope, and the day when our earthly people will take root on this planet should not be far away. ”
