Doomsday Bunker Upgrade

The failure of the eco-environmental experiment did make all the researchers and Chen Xin feel frustrated, but it was only a dozen failed experiments, which did not make people lose their fighting spirit.

Moreover, just adding animals will always lead to the collapse of the entire ecosystem. If it is only plants, it can keep the entire ecosystem in a relatively stable state for at least five hundred years.

This also proves that the construction of an artificial ecosystem is feasible, but compared with the relatively stable and controllable situation of plants, animals are relatively more prone to changes, which will cause an imbalance in the ecosystem and eventually lead to ecological collapse.

Chen Xin's initial idea was to add animals to this relatively stable ecosystem consisting only of plants, but previous experiments proved that this was not feasible.

The first few experiments failed, largely due to the mismatch between plants and animals, which prevented the two from co-existing.

In several subsequent experiments, they tried to put animals and plants into the experiment together, but the difference in reproduction speed between different species could easily lead to the collapse of the entire ecosystem.

This is why after the failure of the seventeenth experiment, some people proposed to change their thinking.

Because according to the original thinking, they tried all the solutions they could try, and the facts proved that they had to jump out of their original thinking.

So after finishing the seventeenth experiment, Chen Xin gave everyone a vacation, let everyone rest for a day, change their minds, and see if they could generate some new ideas and ideas.

And he himself tried to adjust his thinking, thinking about the problem.

An ecosystem generally consists of four parts: non-biological environment, producers, consumers and decomposers, and in order to maintain the operation of an ecosystem, these four parts are indispensable.

In Chen Xin's current experiments, the non-biological environment is the best guaranteed, and it is also the most stable of the four parts.

As for the producers, they usually refer to the green plant parts. Although this part is not as stable as the abiotic environment, there is no need to worry too much. They can already build a stable plant ecosystem.

But the consumer part of the whole system really baffles Chen Xin and the researchers.

Although by definition, animals are consumers in the ecosystem from the bottom to the top, but in fact every link in the entire food chain can be regarded as a producer and consumer.

What they consume is the lower level, and they themselves will be consumed by the upper level of the food chain. In the end, the existence at the top of the food chain will be decomposed by the decomposer after death, forming a closed loop of the entire material cycle and energy flow.

So the supply and demand relationship between each species and other species is the key to maintaining the balance of the entire ecosystem.

This is like a production line. Raw materials are input from the source, and the processing workshop processes the raw materials into parts, which are then assembled in the assembly workshop. The amount of work to be done in each link is calculated in advance, neither more nor less.

If there is more or less in one of the links, it will cause problems in the entire production line.

Too much will lead to more and more things in a certain link, and less will lead to fewer final products on the production line.

It's just that the production line in the factory can be adjusted directly, but the ecological environment is obviously not so easy to control and adjust.

Although human beings can indeed play a regulating role in the ecological environment of the dome city, so that the entire ecological environment can last longer, but if the ecological system itself is problematic, even if there is external force to interfere with it, it will only run for a longer period of time. It will eventually collapse.

Moreover, if there are problems in some aspects, it is difficult to save the entire ecosystem even with external intervention.

This point can be clearly seen in the sixteenth and seventeenth experiments before. The mass reproduction of insects set off a terrible scene like a locust plague. Even if human intervention is involved, the final result is that the entire ecosystem must be rebuilt.

Of course, that would lead to such a result, but also because there was no external force to interfere, and the entire ecosystem was completely out of balance.

If there is a monitoring system that can monitor the entire ecological environment at all times, and deal with problems and variables in a timely manner, to a certain extent, it can indeed maintain the operation of the entire ecological system.

As long as there is no problem that causes the entire ecosystem to collapse in an instant, this will actually allow the entire ecosystem to run smoothly for a long time.

But Dome City can do this, but if you want to restore the ecology of the entire Blue Star later, it will definitely not work.

After all, humans currently do not have such a powerful force to monitor the ecology of the entire Blue Star and make timely adjustments to possible problems.

Therefore, Chen Xin must find a possibility that allows the entire ecosystem to run smoothly without external interference.

But how easy is it?

Giving up thinking about this problem, Chen Xin decided to let his mind rest for a while, and change his mind to see if he could have new inspiration.

So he left the scientific research center and returned to his home.

Back home, Chen Xin noticed that Qin Lan was sitting on the sofa sorting out something, so he walked over curiously and asked her, "What are you looking at?"

"Some photos, among the things Qing Yan brought back, there are many old photos, so sort them out." Qin Lan answered Chen Xin's question, and at the same time looked up at him: "Why did you come back so early today?" ?”

"I encountered a little obstacle at work, and the experiment failed again, so I just gave everyone a day off to let everyone have a rest and change their minds." Chen Xin said this, sat down beside Qin Lan, and picked up her tidy bag. A good photo album flipped through.

Most of the photos above are photos of them having fun in Mo Qingyan's bar before, and some of them were taken when everyone went outdoors together.

Looking at these photos, Chen Xin recalled those happy times in the past, and couldn't help but feel a burst of relaxation.

However, when Chen Xin was flipping through these photos, he suddenly noticed that there was something different about one of them.

The one in the photo is Qin Lan, but she is completely different from Chen Xin's memory of her who was always wearing a training uniform. Instead, she was wearing a long plain white dress, and she looked very quiet sitting on a table. In front of the table, and in front of her was a glass ball covered with stones like a fish tank, with small fish and algae.

What really attracted Chen Xin's attention was naturally the glass ball. He asked Qin Lan curiously, "Ah Lan, when did you take this photo? And what is this ball? There is no opening, and the fish inside will not be missing." Oxygen suffocation?"
