Seeing the indescribable danger of Zheng Xin and He Ting looking at him, Li Mu hurriedly arranged for the two to take care of Xiuxiu's mother and son, and couldn't wait to rush back to the laboratory.

Because in the process of Xiuxiu's childbirth, Li Mu made a major discovery. Babies in the mother's womb, supposedly with normal genes from healthy parents, should be born with antibodies. But it still mutated, and the trigger was polluted air.

Since the catastrophe broke out in an instant, it means that something in the air must have reached a critical point in order to make this catastrophe explode quickly around the world in a very short period of time. Otherwise, if it is spread through human bites, the government is absolutely capable of controlling it, and it will not get out of control globally.

With a preliminary conclusion in mind, a large amount of experimental data is needed to support it. This is busy with a group of people outside, Li Mumei called it "special training", and asked Bai Feng and Li Rou to take this group of women whose training has achieved initial results into the mountain, and capture a large number of normal animals and come back to Li Mu for experimental proofreading.

It is not only humans who are infected with the virus, but also animals and plants, so this deep mountain forest is where the danger lies. Compared to the physical fitness of human garbage, even if it is mutated, it is not much stronger. But animals are different, they rely on physical fitness to survive, and the usually docile animals have become fierce beasts, not to mention the original tigers, leopards and jackals. The plant is terrible, it is highly concealed, it covers a large area, and fortunately it will not take the initiative to attack if it does not enter its control range.

If it weren't for the two instructors, Bai Feng and Li Rou, who would have suffered heavy losses, this group of women would definitely have suffered heavy losses. However, even Bai Feng, the elite of the soldiers, was about to be unbearable, and he went into the mountains to train like this every day, and finally questioned Li Mu under the prodding of a group of students below.

"What's wrong? Bai Feng, you can't stand it anymore? Didn't you brag to me about how NB you were when you were a soldier? Looking at Bai Feng, who was pale and pale, Li Mu, who was pulled out of the laboratory, teased.

"Brother Mu, don't blame the instructor, we can't bear it. It's a person who can't stand going into the mountains every day without a little rest! Besides, after those tigers, leopards, and jackals mutated, they were either infinitely powerful or fast. Several times, if it weren't for Big Brother Bai and Sister Rou desperately saving each other, the sisters would definitely have suffered heavy casualties. ”

A few days ago, Zheng Xin and He Ting, who originally had a good impression of Li Mu because of Xiuxiu's surgery, now formed a united front with other women and asked Li Mu, the demon, to give an explanation. For the sake of their own research, they wantonly abused their sisters, Zheng Xin and the others really couldn't bear it.

It seems that he is really angry with the public for the experiment. Looking at the faces of Li Mu who wanted to bite him to death, Li Mu could only say honestly: "Since you want to know, I'll just say it." We've been together for a few months, and we're not outsiders. It's just that I'm afraid you won't understand the reason, so I won't say it. I originally wanted to study the results and then talk about it, but the process in the middle is still quite complicated......"

Li Mu instigated a lot of nonsense, and the taciturn Li Rou couldn't listen to it anymore, and said with a cold face: "Li Mu, don't talk nonsense." It doesn't matter if we understand it or not, you have to say it, don't try to hide everything from us. ”

The cold iceberg had spoken, Li Mu didn't dare to go around in circles now, and tried to use the simplest wording as much as possible, and said, "Do you know photosynthesis?" ”

This group of women has all gone to school, who doesn't know that it's so simple?

Looking at the group of people glaring at him, Li Mu continued: "It's good that you know, you should know the process of plants absorbing carbon dioxide and water and releasing oxygen through photosynthesis. Essentially, photosynthesis is 'harvesting' solar energy. Plants use solar energy to make food, turning carbon dioxide into a carbon chain. The sugars produced by this process can be used as an energy source or to make a variety of more complex molecules, ranging from proteins to DNA.

Whereas, photosynthesis is divided into two main steps. In the second step, electrons enter carbon dioxide to help convert carbon dioxide molecules into sugars. The first step is to obtain these electrons, which is to strip them from a molecule and use them to create the electrochemical gradient needed to drive the second step.

But 3.4 billion years ago, the first photosynthetic bacteria on Earth did not release oxygen, because the molecule that converts carbon dioxide is not water, but hydrogen sulfide, so it is sulfur that is released. But 2.4 billion years ago, the amount of oxygen in the atmosphere exploded in a very short period of time, leading to mass extinctions.

So, I wondered if this catastrophe on Earth could also be a drastic change in the composition of the atmosphere, breaking through a certain tipping point. Why do you think so, because in Xiuxiu's childbirth, there is no possibility that the child in the mother's body will be bitten by zombies, but it is still mutated, and there is only one reason, the air is polluted.

We are okay because at the time of the disaster, those who were in poor physical condition and could not resist the virus mutated, and the rest had antibodies. We are used to the current air, but the newborn arrives in this new environment from a sterile environment, and we can't resist it.

So, I'm telling you guys to go out and help me catch live normal animals, and I'm just trying to prove my theory. At the same time, we will find out the factors in the atmosphere that led to this disaster and study countermeasures. So, you have to keep going into the mountains, and the animals you have caught are in pairs, and it will take time to give birth. Of course, the more research materials the better, so naturally I can only trouble you. ”

Li Mu's tirade made all the women stunned. Sure enough, as Li Mu expected, these women also know simple photosynthesis, and there are a lot of professional terms behind, where do you know what Li Mu is talking about.

However, in Li Mu's simple analogy, everyone still knows a rough idea, and basically understands that this disaster is because the composition of the air has changed. Li Mu needs to experiment with materials and research solutions to end the disaster once and for all.

Although he knew Li Mu's overall plan, he saw that all the female students in his team were basically injured. If it weren't for the fact that Li Mu had a sufficient amount of antiviral serum in his hands, these women would not have been attritional by now.

Hearing that he was going to continue to go into the mountains to practice, there was no human touch at all. Although the women knew that Li Mu was working hard for the survival of mankind, when it came to their own net worth and life, everyone couldn't help but sigh and be demoralized.

Before there was a new discovery, Li Mule's research was so busy that he got carried away. Now seeing that all the women are depressed, Li Mu has never been hard-hearted about his own people.

As a result, Li Mu no longer kept, and in the surprised eyes of Bai Feng, Li Rou and others, he would make Ling Bo move slightly in the courtyard, and he would make Wudang Tiyun fly in the air with his strength.

After Li Mu's performance, Li Mu, who was surrounded by everyone, said unhurriedly: "Bai Feng is your firearms instructor, Li Rou is your martial arts instructor, and from now on, I, Li Mu, will be your light skill instructor." In order for you to train better, I will teach you all these light skills without reservation. ”
