The final exam is to create a closed ecological circulation system!

Meng Yang carefully studied the details of Biosphere 2, and found that there were many loopholes and failures, but the most important thing was that the scientists at the beginning had made things simple. Pen & Fun & Pavilion www.biquge.info

At the time, they probably thought that all they needed was to get some plants, ensure photosynthesis, and ensure that they could absorb the carbon dioxide produced by human respiration and convert it into oxygen.

The idea was not done, and the logic was not wrong, but they clearly ignored the problem of complexity, and in the 21 months of Biosphere 2's operation, a large number of problems were leaked.

Any tiny, unaccounted point eventually became the key point that led to the collapse of Biosphere 2.

For example, the problem of oxygen absorption by concrete by oxidation is something that was not expected, and as a result, the oxygen level of Biosphere 2 has been declining.

For example, the improper introduction of microorganisms causes plants to fail to decay normally and re-enter the ecological cycle.

For example, plants grow slowly in an artificial environment, and their ability to reproduce is underground.

For example, the ant population has expanded viciously, causing ants to crawl everywhere.

For example, too many productive species are introduced, and there is not enough consuming species, resulting in species imbalance.

For example, the extinction of species is underestimated, and as a result, a large number of species go extinct rapidly.

For example, the design of the volume ratio is unreasonable, and the air and space occupied per capita are seriously insufficient.

......

Biosphere 2 is a series of lessons learned, and scientists are right in their ideas and theoretically feasible, but once they are in practice, every factor can become a huge pitfall, and every thought is a trigger for collapse.

An ecosystem is a super-complex system, where thousands of species interact with each other, interact with the environment, and in turn affect themselves. If it could be reduced to calculations, the amount of computation required would be astronomical.

It is such a system, scientists think that it is enough to design photosynthesis, calculate the output of crops, and match all kinds of animals and plants, but the results are naturally miserable.

Biosphere 2 still has at least a large group of scientists to figure out a way, and now this final exam, Meng Yang can only handle it alone, and no one will help him.

For the final exam!

For full marks!

Meng Yang felt that he had to start preparing and verifying in advance.

The first is the location, with Biosphere 2 as a reference, and if he does not want to experience the same failure, then the bigger the ecosystem, the better. The larger the ecosystem, the larger the volume, the stronger the fault tolerance.

The man-made Biosphere 2 in the United States has 12,000 square meters, almost the size of two football fields, and if he were to build it himself, where would he find such a large place? And it can't be discovered, can't be disturbed and detected by others, this kind of place is not easy to find.

Meng Yang's first thought was the ocean, but as soon as he thought of the terrifying pressure on the bottom of the sea, he gave up, with the technology he had accumulated now, it was not difficult to create creatures that could resist water pressure, but it was too difficult to build a huge space of tens of thousands of square meters in Haidian and be able to resist water pressure.

Naturally, Meng Yang set his sights on the valley, if a valley is closed, it seems that the volume is large enough, the question is whether it can avoid people's eyes? This time is most likely measured in years.

If you close a valley, you have to make sure that no one will set foot on it for a year or two, and you have to be able to hide it from the satellites in the sky, which ......

After thinking about it, Meng Yang set his eyes on the underground, and there are also large spaces underground, such as the inside of a volcano, such as an underground dark river, such as an underground sea, or a group of karst caves......

The underground world is just as huge, and one of the good things is that it's hard to spot, it's hard to notice, as long as it's not a place that has been opened up as a tourist attraction, there are always a lot of places that are off the beaten track and haven't been seen for years.

Although the underground world is relatively hidden, Meng Yang is also difficult to find them, which is a problem!

Meng Yang thought about it, called Xiao Budian over, and began to design a brand new creature.

The karst cave groups are usually concentrated in the humid climate zone in the south, all kinds of volcanoes are usually concentrated in various plate tectonic zones, and the underground dark rivers are basically mainly mountainous.

Thinking about it this way, the creature must have the ability to travel long distances, so it must first be able to fly; If it encounters an underground river, it must be able to follow the trend and explore, then it must be able to dive and be able to breathe underwater; If it encounters a cavity buried in the ground, it must be able to drill through the ground to explore.

That is to say, this brand-new creature must be an all-terrain creature of land, sea, air and underground.

Since it is exploration, it must have enough energy reserves to be able to go on long expeditions without being able to replenish it.

It will inevitably face all kinds of extreme environments, and it must be able to move freely in these extreme environments and survive for a long time.

It may face all sorts of sinister situations, and all kinds of backup means must be sufficient, otherwise it is easy to get trapped in a certain environment and lead to complete failure.

It may face a variety of dangers, and it needs to be able to defend itself, and if necessary, it needs to be able to attack, hunt, or kill enemies.

It must have a variety of detection methods and a variety of movement capabilities.

It must be able to draw and label maps, recording all the roads it has traveled.

After such a list of items, Meng Yang found that he had to design a completely new creature, a creature that could not exist in nature at all.

Meng Yang named this new creature - Explorer!

This explorer must have a well-developed brain; Possess a pair of flying wings; To have a pair of lungs is also to have a pair of gills; It must have strong and flexible limbs, be able to run quickly, and be good at climbing, even on steep cliffs; It should be good at digging holes and digging through narrow gaps; It has to have a thick layer of fat; It must be able to endure prolonged hunger and thirst; It needs to have eyes that can see through the darkness; It needs to have detectors who can penetrate rocks; It needs to be able to position itself precisely; It has to do everything it can to replenish its energy, whether it's light or heat......

If you want to have so many functions, such as having all-weather, all-terrain adaptability, it is not possible to accumulate one organ at a time.

Explorers must have the most important ability - Transfiguration!

It must be able to change its body shape when needed, using existing body cells to build the tissues and organs it needs.

It is very difficult, but fortunately, it is not impossible to achieve, Meng ** According to the actual needs, he slowly outlined the genetic outline of the explorer.
