In Zhang Zhi's mind, he began to recall the role of these two super plants.

Black radish remembers very well that it does not need photosynthesis to exist in nature.

Its main function is to remove radiation contamination. It can absorb the energy in the rays and supply special cells for the synthesis of substances.

Cuscuta is a parasitic plant that mainly absorbs carbon monoxide and carbon dioxide.

In extreme cases, it can also absorb organic gases such as methane.

Harnesses the host's energy to make nutrients and spit out a high concentration of oxygen.

Zhang Zhi thought about these two super plants, and what they could do with each other.

He was still a little unconvinced, and said tentatively: "These two plants, they can complete the cycle between carbon dioxide and oxygen, which is also amazing." ”

Li Lingqiu also nodded in agreement, and she said, "I didn't notice at first, the combination of the two plants has such a great effect. ”

Li Lingqiu waved her hand, and a light curtain appeared in front of her, with a news report on it.

This is news about the island nation, found in the Tokyo Bay area.

There are many insects that appear atavistic, 30 cm long blood-sucking mosquitoes. 10 cm thick centipede. A palm-sized dragonfly.

There are also a lot of strange-shaped insects, and the people there are very disturbed by them. There have been a number of accidents in which insects have attacked humans.

Scientists on the island analyzed that the radiation concentration there was too high, which led to genetic mutations in insects.

Some people have retorted that it is impossible for all insects to be genetically mutated, which is obviously an atavistic phenomenon.

Finally, after a joint investigation by the scientific research institutions of the island countries, it was found that the oxygen concentration there was too high.

Its oxygen concentration is almost the same as that of the Earth in the late Jurassic period.

If it is not for a short time, dragonflies up to 3 meters in length and crickets about the size of pigs may appear.

In the end, they found out that the culprit was a plant parasitic black radish, where a chemical company happened to be secretly discharging sewage.

Li Lingqiu pointed to this news, and she said with a smile: "If it weren't for this report, it would have caused a big discussion in the international biological community."

I don't see the effect of these two plants together yet. ”

Zhang Zhi was also very emotional, and he has not paid attention to the biological world. Even the news of the island country is not too important, and he passes it by.

He then had some questions and asked Li Lingqiu: "The oxygen cycle has been solved, the water cycle and the atmospheric cycle, how did you solve it."

These two problems are much more difficult than the oxygen cycle. ”

Li Lingqiu pursed her lips, and she explained: "I say it's a pseudo-biosphere, of course, it's a machine to solve this problem.

It was originally a small biosphere, and the atmospheric circulation was directly used by a blower.

The water cycle is carried out directly through artificial rainfall and drip irrigation. ”

Zhang Zhi was stunned, and he said directly: "Is this still a biosphere?"

It's not like it's a big farm, and you're not saying it can recycle itself. ”

"You don't look at how bad the conditions are, and you want the perfect biosphere.

When I say that the biosphere is self-circulating, I mean the circulation of matter between biological chains.

To fully simulate the biosphere on Earth would be impossible with current technology. ”

Zhang Zhi also felt that he was a little ambitious, nodded and said: "This is also very good, in fact, there is a biosphere that can carry out basic cycles, which is already very magical at this stage." ”

Hearing Zhang Zhi's praise, Li Lingqiu said happily: "Look at the biosphere I made, these creatures are carefully selected by me, and their vitality is very tenacious. ”

Zhang Zhi stared at the biosphere, which was separated by a glass wall.

There is also a transparent light curtain on the glass wall, which randomly shows the life behavior of the creatures in the biosphere.

He heard Li Lingqiu say that life is tenacious, and he glanced at the light curtain a few times, and sure enough, he found the figure of a cockroach in the shadows.

This is the basic scavenging insect that plays an important role in the biosphere.

It can decompose the bodies of animals and plants after death, and ensure that each substance is recycled in the biosphere.

The cockroach is extremely tenacious, and it has survived on Earth for 400 million years.

Even if the head is removed, it can survive for nine days, and the cause of death is extreme hunger.

This biosphere has several rare plants. As far as you can see, there are several kinds of tenacious weeds and two or three kinds of flowers.

Zhang Zhi didn't know these plants, but he could see that they belonged to the weeds on the side of the road, and basically no one paid attention to them on the earth.

The only thing they have in common is that they are extremely tenacious.

The large animals in the biosphere, Zhang Zhi can recognize them all.

There are only two or three types of birds, including the common swallows and sparrows, as well as owls.

Large goshawks, which already belong to the top of the food chain.

Animals include rats, several species of snakes, rabbits and wild boars.

He also saw a family of three with three wolves.

There are many insects, except for a few insects such as bees, locusts, centipedes, etc., most of them are unknown to Zhang Zhi.

He also saw several common crops for humans, growing in the biosphere.

Corn, potatoes, tomatoes, cucumbers.

Zhang Zhi asked Li Lingqiu: "Put in a few crops, I know that this is to test whether they can grow here."

Why don't you choose water beans, or my favorite rice, rice? ”

"There is not enough water, and it is difficult to survive without taking care of it. Li Lingqiu explained the reason very simply.

Zhang Zhi smiled awkwardly, and he continued to look towards the biosphere.

Suddenly I noticed a strange phenomenon, there was a red-eyed, gray-white rabbit.

It actually walked up to a big fat bug, and the bug's body had a lot of small tube-shaped objects.

The rabbit came here skillfully and bit into the small tube.

Zhang Zhi can't understand what this rabbit is doing?

He turned his head to Li Lingqiu and asked, "What is this rabbit doing?" ”

"Drink milk. ”

Li Lingqiu replied with two words briefly, and she was also observing the behavior of the rabbit.

Zhang Zhi's expression was very strange, and he said solemnly: "Lingqiu, you can't use genetic technology to change rabbits." Rabbits have learned to drink milk, and how do we eat rabbits.

What that big bug is, I've never heard of it. ”

"Change your hair, your rabbit is born to eat grass. Mammals, do you understand. Li Lingqiu replied a little angrily.

She explained the big bug briefly.

"This is the animal that I genetically modified, and I added mammalian genes and photosynthetic genes to it.

It only needs to be irradiated by a light source, by absorbing carbon dioxide and water from the air.

It can produce a steady stream of milk in the body, and I named it the milk worm. ”

Zhang Zhi didn't bother with Li Lingqiu's attitude, he continued to ask: "How do you teach rabbits to learn to drink milk, I think this looks like an adult rabbit." ”

Li Lingqiu said lightly: "Creatures have strong adaptability to the environment, as long as the rabbit is hungry for a few days.

Then use artificial methods to teach them to drink milk, and the rabbits will learn this way of behavior.

They all starved to death, and there wasn't enough grass in this little biosphere for them to eat. ”

Zhang Zhi looked at this biosphere, and he felt that Li Lingqiu's methods were a little cruel.

But for the biosphere that survives in space, every ounce of energy must be used. The biosphere has reached its current peak in all indicators.
