But in this dangerous wilderness, humans are the most dangerous.

Teacher Liu looked at the expectant eyes of the children below, smiled proudly, and pushed his glasses.

Chen Yuyang was lying outside the window and said curiously: "Teacher, what does the car look like?

Teacher Liu held back for a long time: "Get out." ”

In fact, Mr. Liu himself doesn't know what the car looks like, the most important thing is that he has never seen it at all, and the news he knows is only heard from others, and then everything is arranged according to the logical relationship.

Chen Yuyang has a toothache, he and Mr. Liu have not known each other for a day or two, generally when he doesn't know or doesn't know how to answer, he will use the all-encompassing word "roll" to cover the past, saving trouble and effort, and there is no lack of setting off the tallness of a kind of knowledge, which is simply a triple win.

Teacher Liu continued: "Now in the world we live in...... To be precise, in the wasteland, all creatures have undergone shocking mutations, take rabbits as an example, before the catastrophe, they were small pets raised at home, docile and cute, and they would sell cute. ”

The students didn't believe it, because the smallest rabbit is half a person as tall as now, and it can jump so far, which has to kick the human head, and the head will be a hole, this kind of thing is still dare to be raised, although the rabbit still only eats grass no matter how it evolves, but that pair of scarlet eyes, how can it not be compared with cute and docile!

"In addition to rabbits, there are also cattle, sheep, dogs and rats, these creatures are also changing, of course, they all maintain their original nature, cattle and sheep eat grass, mice like to steal things to eat, like to live in the dark, as for the dog ......" Teacher Liu thought for a while: "Maybe I still like to eat!"

This last sentence tasted so good that the children in the class all made vomiting expressions.

Chen Yuyang didn't think there was anything wrong, at least the dog was smart enough, in this wasteland, in an environment where any food was scarce, there was no guarantee of, at least it wasn't poisonous.

"In addition to living things, there are also plants that are also mutating, take the Chinese cabbage, garlic seedlings, coriander, radish, potatoes that we often eat, for example, after you shrink him tenfold, that is what they looked like before evolution, as for why they evolved, a scholar once told me that this is God's mercy on human beings, and cannot bear the death of human beings in calamities, so let these foods also evolve, originally two cabbages were enough for a family to eat, and now a cabbage is enough for a family to eat for many days, this is a gift from nature, we must know how to be grateful。 Teacher Liu opened his mouth and said, this Chen Yuyang agreed, because if there is no food after these evolutions, there may be very few human beings who can really survive, in the face of the harsh environment, evolved beasts, even if humans take up arms, they are still the weakest race, of course, some people will say that the human beings in the past did not have a thermal weapon enough to conquer the entire universe? But now, even if there is a complete set of thermal weapon manufacturing drawings, it may not be able to be made, because with the fall of civilization, there has been a discontinuity in knowledge, even if you have the entire thermal weapon manufacturing map, you may not be able to make a weapon, and even if you can make it, it is definitely in the hands of a very small number of people, because people know that as long as they master the thermal weapon, it is equivalent to mastering the power enough to challenge the gods, so they don't know at all.

Let's take a feline animal as an example, the feline animals are tigers, lions, leopards...... Because felines are mammals, they have similar bones to humans, subcutaneous tissues, and have a strong explosive power, they have this kind of fun that likes to play with prey, and will only eat after the prey is exhausted, and at the same time, this creature has a strong running ability, if you encounter it in the wasteland, the first thing to do is not to run, because you can't run at all, rather than wasting your strength on escaping, it is better to turn around, and in the face of the feline attack, do not turn your back to it, because that will make him more interested in hunting, you have to stop and look directly into his eyes, Find the moment it pounces and aim at the vital point to shoot quickly, then you have a good chance of surviving, of course, it is possible that they will give up on you as a prey, but only if you can show enough to deter them. Teacher Liu opened his mouth and said that he actually saw this on the tree: " Okay, then I'll talk about the lethal points of these animals, first, the eyes, when you have the opportunity to attack the eyes of these animals, don't leave your hands, attack its eyes fiercely, as long as you cause visual damage to him, then the chance of survival may be greater, followed by his neck, when mammals hunt, the first point of attack is the throat, biting off the throat, which is equivalent to directly abolishing the prey, which is not what they learned, but because their own weakness is in the throat... ...”

Chen Yuyang coughed dryly: "Teacher's maned dog?"

The corners of Mr. Liu's mouth twitched: "Get out, I'm not qualified to speak outside the window." ”

Chen Yuyang said that he was very helpless, shouldn't he be praised for loving learning and actively asking questions?

Mr. Liu must have forgotten about the maned dog, otherwise he would definitely give another example, who made this thing's hobby so unique and likes to bite the butt.

"Of course, if you have a head-on conflict with these mammals, you must react quickly enough to ensure that their claws will not hurt your body, because their nails are full of bacteria and viruses, and they are also very sharp, even if it is a slight stroke, it will make your skin open, in our town, the level of medical care is limited, antibiotics are very rare, not to mention the rabies vaccine, so you must be careful after encountering, you must not be scratched, otherwise even if you survive, you will not escape death." Teacher Liu thought for a while and continued, he really didn't want to say more when it came to the medical level of the displaced area, and once again he had a wisdom tooth and wanted to ask if he could pull it out, but the doctor said yes.
