Ten days later, Ren Ruofeng received an official notice from the head of the Biosphere Programme.

"That's amazing! Those two masters completed their research so quickly! It's a perfect realization of the design of that great god, and it's also a programmable bacteria! The person in charge said ecstatically.

"Uh......" Ren Ruofeng was quite shocked when he heard this.

He is not a novice, and the meaning of programmability is very clear, which means that this bacterium can edit various functions to a certain extent, and freely combine the functions it wants, of course, this editing naturally has a scope.

The person in charge gushed: "This bacterium can do a lot of work, it can replace chlorophyll, and the efficiency of synthesizing organic matter is 150% higher than the former, it can also decompose all kinds of garbage, even including plastics and other substances that cannot be decomposed by conventional bacteria, the efficiency is also very high, as long as the bacteria are set in advance to decompose the object molecular formula......

"Wait, will it be able to decompose living things too?" Ren Ruofeng hurriedly asked, things are good, but there are no hidden dangers.

"How is that possible? All its functions are built with reference to the organisms in the existing biosphere, but with large-scale enhancement, we can completely control the scope of its decomposition, and it is impossible to endanger normal life. The person in charge hastened to explain.

"That's great, you start writing the most detailed test plan right away, making sure that all the extreme conditions are covered. As for the testing site, don't put it in that giant greenhouse until I find you a safe enough place. Ren Ruofeng said seriously.

"Alright then, I'll wait for your arrangement." The person in charge also knows that the better the thing, the greater the hidden danger.

Just like the antibiotics that save countless people, they also give birth to superbugs in the end, once infected, there is no medicine to deal with, and a small illness can directly drag people to death.

This is because of the consequences of the early misuse of antibiotics.

Ren Ruofeng hung up the phone and began to think, where is this safe enough place?

In short, it can't be put in the outside world, once it leaks out, it is a big hidden danger.

Preferably a place completely isolated from this world.

Inheritance Secrets?

No, that's where Shenzhou is fundamental, and if something big happens, if nothing else, there will be a big problem with food supply.

Other secret places?

But will they let them in? It's not about sending money, it's about sending experiments......

However, he still had the idea of trying it out, and sent a message to Xia Kejia, who let that guy have the most secret realms in his hands?

…………

System space.

"This old man Ren, why do you always look for me?" Fang Ning was secretly reading a copy, and was suddenly >, "The greater the ability, the more people will look for you, if you are just a salted fish, then no one will look for you." Uncle gave Fang Ning a bowl of chicken soup.

“…… If you are salted fish, you will be hung up," Fang Ning said speechlessly, and then looked at the WeChat content, and at a glance, he suddenly became happy, "Sure enough, it succeeded, if this kind of thing is really reliable, we will also make great use of it." ”

"But he said that a lot of testing is needed to confirm whether it is reliable or not, where are you going to arrange for the test?" Uncle asked.

"Where else can I put it? Of course, it was placed in the subspace sent to us by the black robe, which was similar to the earth's environment, and was just used for various tests. Fang Ning came casually.

"Isn't it a bit stupid to give us such a good thing, and in the end, he even gave it himself." Uncle scoffed.

"I'm not sure if he's stupid or not, but I'm pretty sure you're stupid," Fang Ning said disdainfully, "That subspace, I took a closer look at it when I went in last time, it was actually not stable, and it looked like it was going to disappear in thirty years." ”

"Why? I didn't even notice a system like I'm so proficient in the laws of space, how did you find out? The uncle didn't believe it at all.

"That's because you don't understand science. I have carefully observed that the rotational speed of those planets is steadily decreasing, and after 30 years, the rotational speed will decrease to a critical point, and then under the action of gravity, with a 'boom', the planets will crash into the sun, and then disappear completely, they are gone, and this subspace will naturally be useless. Fang Ning said with disdain.

"Damn, no wonder that black robe was given to us so simply, it turned out to be just a defective product." The uncle said indignantly.

"It's good to be able to use it for decades, and like this one, at least it can be used for a lot of experiments." Fang Ning said lightly.

…………

subspace.

Ren Ruofeng followed Fang Ning through the black ball and came to this novel and familiar place.

The novelty is because in his opinion, the alien space is similar to the inheritance of the secret realm, but there is only a piece of land, but here is completely different, this is actually a small universe.

Familiar because it's a lot like a second earth.

The sun and moon are above and the blue planet at your feet.

"It's literally a replica of the solar system." He said from the bottom of his heart.

"That's right, you're not wrong at all," Fang Ning agreed, "There aren't any humans here, so you can experiment here as much as you want, and it will definitely not affect the outside world." ”

"Thank you so much, the universal bacteria are indeed very powerful, but we don't know what hidden dangers it has, but since it is the design of the plague god, there will definitely be hidden dangers, and we need to test it out and improve it." Ren Ruofeng nodded.

"Thank you, don't need it, when its safety and reliability are certified, I will also need this thing in my secret realms." Fang Ning said lightly.

"It's natural, and we'll have a technician come to guide you when the time comes." Ren Ruofeng naturally accepted the other party's request without hesitation.

Although the secret realm is good, there is one of the biggest problems, that is, the ecological tolerance is very poor. After all, it's a semi-enclosed space.

Although substances such as sunlight, water, and energy can communicate with the outside world, only living beings cannot communicate freely.

This leads to the fact that in the outside world, because of the endorsement of the whole earth, hundreds of thousands of square kilometers can easily accommodate hundreds of millions of people.

But in the secret realm, there are millions at most, or even only a few hundred thousand.

Fangning's righteous city now has a permanent population of only 300,000, which is not as large as the population of a prosperous county in the interior of China.

The reason is very simple, the production and life of hundreds of thousands of people, the inevitable pollution such as waste and garbage can also be digested by these lands.

Accommodating more people would only lead to an ecological catastrophe, as the collapsed Biosphere One programme can know.

Biosphere No. 1 is because the area is too small, there is a problem in a certain link, resulting in the ecological cycle can not be carried out, a large number of animals and plants produced ecological waste can not be degraded, can not return to the natural cycle, and finally had to declare the experiment failed, the earth is still the only biosphere that human beings can rely on.

And with this versatile and highly functional universal bacteria, these problems can be solved.

As a result, the population that can be accommodated in hundreds of thousands of square kilometers of secret land will rise sharply.

The only thing that can limit the number of people is the upper limit of various living goods, not the limitation from nature itself.

The urban area of a capital city is only a few hundred square kilometers, but it can accommodate tens of millions of people. Of course, the supplies they need are supplies from one country.

According to this scale, more than 100,000 square kilometers of land can accommodate at least tens of billions of people.

And this is still a conventional way of living, and if it all becomes a high-rise building, the number of residents can be increased several times.

This is where Ren Ruofeng's confidence in the "50 billion Shenzhou people" plan lies.
