Then I pressed Mr. Liu on the operating table, of course, looking at Mr. Liu's identity, the medical expenses were also discounted, but when the doctor walked in with the dismantling forceps, Mr. Liu's liver trembled, although the conditions were a little harder, you brought a tool pliers over and I also recognized, anyway, as long as you can pull out the tooth, but you at least give an injection of anesthetic!

This time it was the doctor's turn to be confused: "There is an anesthetic, but I can't use it, where can I get it?"

The little nurse on the side thought for a while: "Let's hit the leg!"

Doctor: "???"

Little Nurse: "That way, he won't be able to run away when he's in pain." ”

Teacher Liu: "I thank you so much for your whole family!"

At that time, Mr. Liu didn't pull it out, even if he had wisdom teeth full of mouth, he didn't pull it out, it was so scary, anesthesia hit the legs, this doctor was afraid that he was a veterinarian!

Getting back to business, Mr. Liu continued: " When we ensure that we are safe enough, we have to find a way to attack the target, when attacking, we must pay attention to everything around us that can be used, such as big trees, stones, dirt pits, everything that can be used to cause trouble for the prey, we humans do not have hard claws, nor do we have particularly solid skin, it is difficult for our fingernails to penetrate the skin of these animals, so we need to use tools, I think the reason why we have been the ruler of this planet in the past civilization may be related to our ability to use weapons！”

Chen Yuyang agrees with this very much, he has encountered this mammal many times in the wasteland, and he does not have any particularly sharp weapons on his body, relying on the surrounding terrain and sharp stones, those weapons that can cause damage.

"Teacher, wolves should also be mammals, so what should we do if we encounter wolves?" Chen Yuyang couldn't help it, maybe he was a person like him who was diligent and good at asking, if he met a teacher with real materials, he would definitely like a student like Chen Yuyang, otherwise this teacher would go to class, day by day, after the lecture, there was no squeak, except for gossiping and deserting, this is completely like giving a lecture to Robbie cabbage, which is not interesting at all, so the teachers prefer students who like to ask questions.

But Mr. Liu, he may only have half a bowl of water in the ocean of knowledge.

Teacher Liu thought about it, and this time he didn't use the shameful word "roll", pushed his glasses and said: " Wolves are indeed mammals, but within the scope of our two hundred and two sky cities, wolves will not appear at all, because when building the sky city, those private armed forces have completely eliminated the threats in the area, so they will not encounter wolves at all, but there are exceptions to everything, in case you really encounter wolves in the wasteland, then Chen Yuyang, as a senior hunter, what do you think should be done?"

Chen Yuyang thought for a while: "I might run, and then find a good place to face the water and back the mountain." ”

Teacher Liu: "Hide, use the mountains as shelter to ensure your safety, and at the same time, where there is water, there will be wild animals coming to the river, so that you will not starve to death, which is a good suggestion." ”

Chen Yuyang shook his head: "This place has good feng shui and is suitable for being a cemetery." ”

The whole class was in an uproar, and even Teacher Liu's expression was a little stuck, a special cemetery.

But Mr. Liu really can't refute Chen Yuyang's choice, yes, once he becomes the prey of the wolf, unless he has absolute divine help, he can't survive at all, the wolf is a social animal, a creature that encircles the prey in a team, once he attacks the prey, that is, the wolves have made all the preparations, and even the retreat has been arranged, so when they meet the wolf, there is no way to live at all, but all the children in this class are children, if they are allowed to face this kind of life and death decision so early, will it be a little cruel, but now this is the case on the wasteland, even if he doesn't talk about it, sooner or later these children will understand, sooner or later, you will know, Mr. Liu is a little entangled in his heart.

"That classmate Chen Yuyang just now said that even if we die, we can collect blessings for future generations and bless future generations......"

Chen Yuyang is simply impressed by Mr. Liu's nonsense, this person is gone, maybe there will be a future or not, and it will benefit a fart.

"By the way, in the wild, I will give you a few situations, some things can be eaten, and some things must not be eaten, because after eating, it can send you away, and you will not be greeted without a fight. ”

"In the wild, as long as you encounter the juice of the white liquid, you must not drink it, because there is absolutely poison and toxicity in it, and the water that flows down from the tree, as long as the color is clear, then there is a 50% chance that it is not toxic, do not drink it when it is not critical, you can choose the needle-like leaves to choose to take water, although it is a little less, but the water in the needle-like leaves is absolutely drinkable, and there is another kind of water that is absolutely safe, that is, mountain spring water, generally mountain spring water is very common in caves, mountain spring water has been purified by the mountain layer by layer, and has reached the point of absolute purity, it is okay to drink directlyBut don't drink too much, if you really want to drink, you can find a vessel that can be heated, and boil for more than 10 minutes before drinking. ”

"Water is the most indispensable part of our body, hungry can still persevere, once the lack of water in the human body will continue to decline, until you are weak, faint on the wasteland, after talking about water, let's talk about food, there are a lot of wild fruits in the mountains and forests, and in our homeless areas there are many people will collect wild fruits from the mountains and forests, and then sell them in the homeless areas, but there are a lot of wild fruits here that can not be eaten, because the wild fruits contain a lot of toxins, there may be nothing at the time, the toxins are lighter and they will pull a few days of stomach, if the toxins are heavier at the time of eating, they will have convulsions, foaming at the mouth, suffocating to death, wild fruitsThe lighter the color such as turquoise, light red, yellow-brown this fruit must not be eaten, because these fruits are highly poisonous, and then those lilac, purple fruits, these fifty percent poisonous, unless it is about to starve to death, do not try, otherwise this is no different from starvation, and then those black fruits, even dark red fruits, these fruits can be eaten, but some will be particularly sour, there are also special sweet, of course, if the entrance is astringent, then quickly throw away, astringent fruit eating must not be good for the body, will cause a big incident。 ”
