Zhang Yuntian clearly remembered that in the basic course of medicine in the future plane, he once talked about the importance of decomposers to nature, especially the bacteria and fungi that mainly decompose human and animal corpses, it is said that the fastest digesting fungus only needs four or five hours to divide a corpse into bones, and after another ten or so hours, even the bones will be digested by the corrosive liquid they secrete.

(Note: Mushrooms belong to fungi, but there are many forms of fungi besides mushrooms, such as molds and yeasts)

The land resources of the future plane are limited, and there is no extra place to place the ashes, so the remains are processed in this way, and the nutrient solution obtained from the decomposition is re-watered back into the cultivated land, which is called the natural cycle of energy.

But four or five hours is still a bit long, if the mutated zombies attack the city, let alone four or five hours, I'm afraid that I can't even stand it for an hour, those things are not as stupid as ordinary zombies, stupid and slow, they move extremely quickly, and mutate into claws and solid bodies, and even some have special abilities, which makes people unguardable.

If you can cultivate a special kind of decomposer, which can accurately locate the brain of zombies, and give priority to decomposition and destruction from this part, the speed of destroying zombies will be doubled.

Without further ado, Zhang Yuntian twisted the ring slightly, came to the future plane, opened the textbook, and began to read chapter by chapter.

The reason why the original Zhang Yuntian was reluctant to learn was not only because he was greedy for fun, but more importantly, he was very confused and didn't know what was the use of learning these things?

In today's world, the health of all people is controlled by the bracelet, and even if there is an accident with a comminuted fracture or massive hemorrhage, the central system can easily bring the dead back to life, so there is no hospital here.

In addition to entering the graduate school to constantly create viruses for themselves, crack them, and do these boring jobs over and over again, another employment channel is to enter the Center for Disease Control and Prevention, which is responsible for maintaining the normal operation of the green health program.

However, the above two job contents do not have too many requirements for the professional knowledge learned in school, which is equivalent to a complete waste of time in college in the past few years, it is better to squander your life, at least you will have a happy memory.

Now Zhang Yuntian is different, he comes to learn with problems, this is called applying what he has learned, there is a good saying, "a ship without a sailing target, the wind in any direction is a headwind", when he has the purpose and goal of learning, he does not need to be supervised at all, he himself began to learn automatically and consciously, and even found fun and a sense of accomplishment from it.

When people concentrate on one thing, time flies.

In the blink of an eye, the "joyful" thunderstorm holiday ended, and the students began to return to school one after another.

In addition to the buildings, most of the plants on the playground have been charred, and from a distance, it looks black and dark, like the land that has just been ravaged by war.

However, this also created their ability to regenerate quickly, although only two days after the thunderstorm, the grass was the first to emerge young green shoots again, and the half-burnt woody plants also started to repair themselves, growing small flower buds on the charred surface.

In this world, this season is called spring, the spring of the revival of all things.

When Zhang Yuntian appeared on campus, it immediately caused a sensation.

"Look, this person is Zhang Yuntian, the most potential genius in the second grade of the school!"

"Shouldn't the most talented person in the second grade be Long Haochen, how did he become Zhang Yuntian?"

As soon as a chubby girl said this, she immediately aroused the surprised eyes of several girls in her peers, "Oh my God, you don't even know such a thing?" ”

"Zhang Yuntian not only defeated Long Haochen by playing games, but also replaced Long Haochen in the final exam and won the honor of the special scholarship!"

"Yes, yes, and he's also the creator of the G virus, which is said to have created a new category of viruses! Generally, people who can do the level of planting must have thirty or fifty years of experience in virus research, even so, they must have extraordinary talent, but this Zhang Yuntian, who is only in the second grade, has not even learned all the courses, can do this kind of process, can be regarded as a person who has never been seen before or since, right? ”

"Compared to these, what you said is nothing, I think Zhang Yuntian is so handsome!"

"Cut, nymphomania!"

The number of female students in the medical school has an absolute advantage over the male students, and the academic genius is as eye-catching as a star, along the way, you can often see the girls who cast envy, jealousy and even admiration for Zhang Yuntian, they are in groups of three or five, or quietly cast a hot gaze at him, or whisper, and occasionally burst into laughter.

"Hey, Yuntian, it's early!"

Chen Lu intercepted Zhang Yuntian at the door of the dormitory.

"Hehe, I'm suffocating at home, so I finally started school and came out to breathe!"

Zhang Yuntian said with a smile.

"Let's go, let's play for a while, tomorrow I will fall into the endless sea of learning again, I have to relax and relax, so that I don't drown!"

"Okay, if you don't play for a holiday, I don't know if your summoning hero level has dropped!"

Zhang Yuntian is very keen on this kind of holographic game, and that sense of impact is definitely not the kind of thing that is piled up by music and images in the main world, "Do you want me to teach you a few more tricks?" ”

Chen Lu had a longing expression on his face, "Okay, okay, you have to teach me more, in the future, I will represent you to fight all over the invincible opponents of the whole school, and see who dares to say that I have no talent!" But this time..."

He smiled and said mysteriously: "Let's go play a different game first, have you ever played a live-action version of the war game?" ”

"War games, and live-action versions?"

Zhang Yuntian looked stunned, the war game is actually a simulation of the world war hundreds of years ago, divided into three combat modes of sea, land and air, there are individual combat, there are also group confrontations, it is a very strategic holographic game.

But this is the first time I've heard of the live-action version, do you want to drive a real plane and tank to participate in the battle? Although it is said that as long as people are not broken, the health system will automatically restore the functions of the human body, but is this too exciting?

Looking at Zhang Yuntian's incredible expression on his face, Chen Lu smiled even happier, "Of course, I didn't expect it, let's go, it's morning, and the time is still in time, otherwise I won't be able to go back to school before dark!" ”
