"In addition to the selection of the top twenty, the first actual battle will start in a month, during this time, everyone hurry up and cultivate, although there will be a danger of death, but as the head teacher of the second class, I will also do my best to ensure your safety!" Qin Wudao. Pen "Fun" Pavilion www.biquge.info" In addition to this matter, after you enter the martial arts class, martial arts cultivation will become the main part, as long as you can ensure the results of the liberal arts, you can send me a message directly if you want to ask for leave, but if you can, I still hope that you don't keep asking for leave, because there will be a lot of courses taught in the school, including how to deal with demon beasts, as well as the types of demon beasts, how to separate, the different weaknesses of each type of demon beast, etc., these things, if you miss it, you can't make up for it in retreat!"

At this time, one of the students raised his hand and said, "Teacher, what should we do if we want to practice hot weapons?"

Many students nodded, cold weapons are good, but many people also want to use hot weapons, which is obviously much easier, cold weapons fight life and death, but hot weapons can be knocked down with one shot.

"Hot weapons, in principle, are not allowed to be held by civilians, either you go to join the army, and soldiers can hold hot weapons, or you have to find a way to pass the assessment of the firearm holding license!" Although from the level of using tools, there seems to be no difference between using firearms or cold weapons, but if you want to go further on the road of martial arts, it is best to focus on your own practice, even if the snipers in the army, sharpshooters, or mecha pilots also have high requirements for the quality of the warrior itself, and now the newly developed large-caliber sniper rifle can break the head of a demon beast with one shot, but his recoil is also terrible, like yours The recoil of a shot is enough to collapse your entire shoulder, the more the weapons of modern society develop, the higher the quality requirements for people themselves, so paying attention to their own development is the right way！”

Qin Wu himself is a retired instructor of the special forces, so many people believe what he said.

Chu Yunfan also secretly agreed in his heart that the biggest difference between humans and beasts is that people can use tools, but no matter what tools are used, talent is the foundation of everything.

Moreover, the path of martial arts has been cultivated to the extreme, and picking weeds by hand can cut the sun and the moon, this kind of power, unless humans can develop the legendary Star Destroyer, may be able to barely match it.

Therefore, he also firmly believes that his own development is king.

"Okay, now that I've finished saying everything, it's time for class, I'm your homeroom teacher, I'll explain to you below, about the types of many demon beasts in the world now, as well as the general distribution, which can be regarded as broadening your horizons!" Qin Wu said.

"The current demon beasts are probably divided into the demon beasts of the Kunlun realm, as well as the native demon beasts of the earth, and among them, the native demon beasts of our earth will be much weaker, because the earth cataclysm is only a few hundred years, but the Kunlun realm has existed for I don't know how many tens of thousands of years!"

"The Kunlun realm is too far away, and you will probably only come into contact with it when you go to college, so I will tell you about the earth's native demon beasts, the earth's native demon beasts are roughly divided into, land, sky and ocean, these three categories, in recent years, some space species have been discovered one after another, and the demon beasts that can survive in space, because the number is not very large, and it is a variant of the sky species, so it will be classified into the sky species of demon beasts first!"

Qin Wu's words immediately caused many students to be in an uproar, because everyone knew that space was not suitable for human existence, but it was not suitable for all living beings at all, because there was not even air over there.

The first problem faced by human beings in space is not that there is no air, but that the pressure inside and outside the body is unbalanced, and they will explode and die directly.

"Teacher, how is this possible, let's not talk about the problem of air, there is no atmosphere alone, and the pressure of light is enough for those demon beasts to explode and die by themselves!"

A student raised his hand directly and said.

Qin Wu shook his head and said, "These things have not been announced to the people yet, but after the cataclysm, many of the original truths have been broken, is it really impossible to survive in space?" I can tell you that there are people who can survive in space, and there are indeed people who have done it!"

When many people hear this, they can't help but feel that they have gasped one after another, how strong is it to survive in space, to be able to withstand the imbalance of internal and external pressures in the universe with their physical bodies.

Only Chu Yunfan's expression was calm, because he had already known that in the super ancient civilization, there were strong people who could cross the starry sky, and there was no air in the universe, if it wasn't for his own physical strength to a certain point, how could he do it.

"Teacher, how can the body withstand the imbalance of internal and external pressures, let alone survive without air?" Another student spoke, they didn't believe it, after all, Qin Wu wouldn't lie to them in this regard, but they wanted to know why.

"In the martial arts cultivation of modern society, there is nothing impossible, the physical body is the first step in martial arts cultivation, when you practice all the way, the physical body becomes stronger and stronger, and you will naturally be able to resist the imbalance of internal and external pressure in the universe, it is just a small thing, the environment in the universe is far worse than you can imagine, tens of thousands of degrees of high temperature, absolute zero degrees of ice freeze everything, compared to these, what is the problem of just one air pressure!" Qin Wu replied lightly, As for the problem of breathing, it is even less important, there is a concept in ancient practice, which is called that the flesh-eater is brave and fierce, the grain eater is wise and skillful, the breath-eater is a god and long-lived, and the non-eater is immortal and godly, just like the animal kingdom, what you eat determines your development, whether it is long horns or long claws, for ordinary people, it is necessary to breathe air, but after the cultivation reaches a certain point, it will become a drag!"

"In ancient times, there was a concept of cultivation, called Bigu, that is, not to touch the food of the mortal world, to swallow the aura of heaven and earth, why not touch the food of the mortal world, because there are too many impurities in these foods, for us, these foods are necessary, but for the deeper cultivation, this becomes a burden! They do not breathe air, but aura, so air is not a necessary thing for them! Of course, that is against the laws of nature, and it is also against human instinct, and those who can do this step can not work hard, that is called supernatural power!"
