Wei Han talked about this knowledge that many students have never heard, and now the school will not teach students this kind of thing, and there is no time for students to watch the Discovery Channel, for students who have a vacation every two weeks, the two days of the holiday are eager to spend every minute and every second on rest or play, where will they be in the mood to watch TV.

"Teacher, how do you know if it's a poisonous snake that bites you?"

Wei Han raised the cobra in his hand and said: "First of all, we have to learn how to distinguish between venomous snakes and non-venomous snakes, we can distinguish by their shapes and colors, usually venomous snakes are triangular heads, bright colors and various patterns. Whereas, the head of a non-venomous snake is oval in shape and has a single color. If you can't tell just by these, you can look at its movements, poisonous snakes because they have no strong natural enemies, they are very aggressive, in the wild encounter it not only does not run away, but folds its body and raises its head slightly, this kind of ninety percent is a poisonous snake. ”

Wei Han paused, took out a glass bottle, put a layer of plastic wrap on the mouth of the bottle and handed it to the mouth of the cobra, the cobra immediately bit the plastic wrap on the bottle, a pair of sharp fangs instantly pierced the plastic wrap and then the golden venom flowed down the bottle, and the two fangs were fixed in the bottle and could not be recovered. Wei Han raised his hands and said: "If you are bitten by a snake, then you need to carefully observe the wound, if it is bitten by a non-venomous snake, you can almost not see any wound where you were bitten." But if you are bitten by a poisonous snake, there will be two bloody holes! Look at these fangs, you should be able to imagine what it is like to be bitten by such fangs.

The fangs in the bottle were half a finger long and the thickness of a toothpick, and the students felt chills in their hearts. The students who stood farther away could not see it at all, and they jumped and looked inside, and some even set up a ladder, and there were more and more onlookers. Wei Han put away the bottle, then put the cobra back in the plastic box and closed it, and said with a smile: "That's all for today, I am Wei Han, the survival teacher of class 29, and I will teach everyone how to help themselves escape from danger when they are trapped in the wild and injured! ”

Immediately, some of the students quit, and now they were enjoying it, and hurriedly shouted, "Why don't you do it? Go on! Why can only the students of Class 29 take this kind of class?" The more harmonious one asked, "Teacher, can we also go to your class?"

Wei Han was a little difficult, Ye Huaian only told him how to sell his class, but he didn't tell him how to refuse others to come to his class.

Ye Huai'an walked out in time and said: "Don't be impatient, everyone, the time of our survival class is the third class on Tuesday afternoon, the students have their own classes, our twenty-ninth class can't disrupt your learning curriculum, if you are really interested, I will regularly arrange for Teacher Wei to use his spare time to carry out survival courses in the small hall, and the specific time will be discussed with the school and then announced on the notice board." If you are interested, just pay attention to the announcement!"

The students were a little disappointed, for them, the school is a guy who is unsympathetic and bent on forcing them to study, and such an interesting thing must be out of play.

"I'm sorry, Mr. Wei, I agreed to the student without consulting you. Ye Huaian came over and apologized.

Wei Han smiled as he cleaned up his things: "What's the big deal, I'm too late to be happy to pass on my knowledge to others! The task of the experimental class teacher is too easy, and I've been sick lately." It's best to have an arrangement, but the school doesn't let us do this?" Today's result has made Wei Han very satisfied, although the students are from other classes, but as long as the reputation spreads, plus the activities during the eleventh day, I believe that many people will come to listen to his class.

Ye Huai'an's eyes narrowed and said, "Don't you know if you look at it?"

As soon as the words fell, an angry roar sounded in the distance: "Ye Huai'an, what kind of mess are you doing again!" That voice Ye Huai'an is very familiar, it is the sworn enemy Zhang Xuefeng!

Zhang Xuefeng received the notice that the experimental class had gathered a lot of students on the playground and immediately rushed over, but he didn't expect that it was already a step too late, Ye Huai'an and they had already begun to close the stall. Looking at the boxes on the top of a few tables, he frowned and said, "What are these things!"

These boxes containing snakes are transparent, but they are covered with hay, and now they are covered with blue lids, so Zhang Xuefeng stands too close to see what it is.

Ye Huaian smiled and said, "Director Zhang will know if you open it and take a look." ”

Zhang Xuefeng angrily lifted the lid, and a black water snake suddenly appeared in front of him! Zhang Xuefeng was so frightened that he screamed and retreated again and again and almost fell, but fortunately someone helped him, he was the most afraid of snakes and these things. Immediately said angrily: "Ye Huai'an! What are you doing with these things brought to school! What if you bite someone! Can you afford to be responsible!"

Ye Huaian smiled: "Director Zhang, our Teacher Wei is teaching the students!"

Zhang Xuefeng's face was oily, and he pointed at Ye Huai'an's nose and said, "It's time to eat! You are taking classes here? Why don't you go to the classroom if you want to go to class!"

Ye Huaian still had a harmless smile on his face and said, "Director, you don't care where our experimental class is, right?"

Zhang Xuefeng said angrily: "There are so many students here, and it's not just the students of your experimental class! I can take care of the other students!"

"Yes, yes, yes!" Ye Huai'an said: "Director Zhang is reasonable, but we didn't call them to class, what can I do if they come around by themselves?

"You...... You are using strong words!" Zhang Xuefeng couldn't say Ye Huai'an at all, this guy's eloquence is really good, and all kinds of reasons can block you to death.

"Oh! That's right!" Ye Huai'an didn't answer at all, and said with a smile on his face: "Director Zhang, just now a student asked to come to our class, but I sternly refused! But in order to alleviate the students' dissatisfaction, I told them that we would choose an open class in the small hall after class with Teacher Wei, and ask Director Zhang to help maintain order when the time comes! I'm afraid there are too many people! Thank you, Director!" After speaking, he turned around and left, ignoring Zhang Xuefeng's shouts behind him.

"Teacher, shall we go like this?" Lin Yawen, who had been silently beside her, followed Ye Huai'an and asked.

"Ignore him, the more he cares, the more he will compete with you, just get used to it. By the way, are you interested in snakes? I'll ask Mr. Wei to send you a few to play with. Ye Huaian said with a smile.

"Don't, don't!" Lin Yawen hurriedly waved her hand, this thing is just a little strange, but if you want to raise it, you still can't accept it.

"Haha, I'm kidding. The two were silent for a while, and Lin Yawen said with some hesitation: "Teacher, has your car been repaired?"

Ye Huai'an suddenly stepped on his feet, Lin Yawen almost bumped into it, only to see him touch his chin and sigh and say: "The repair shop said that it can't be repaired, and it's better to buy one for this thing, Jiang Yingwen, this stinky boy, is very heavy, and the parts are all broken." ”

Lin Yawen's expression darkened, she still had deep feelings for this car that had carried her for almost a summer vacation, although she thought that the little turtle was that kind of bargain when she first saw it, but after a long time, she felt that this guy was still quite cute, and now that the little turtle has died heroically, Lin Yawen couldn't help but feel a little sad, and she was even more indignant about Jiang Ingwen in her heart. He said angrily: "Why doesn't the teacher ask him to accompany him? Isn't his father so powerful? Let him pay one!"

Ye Huaian turned around and touched Lin Yawen's head and said: "What happened that day stood in the identity of the twenty-ninth class teacher, I really didn't do a good job, even if it was an ordinary manly husband, he would get angry if he was slapped in the face, not to mention that he was still the eldest brother in the seventy-sixth, and it was normal to lose such a big face and get angry." ”

Lin Yawen raised her mouth and said, "Bullshit manly husband, if he were a man, would he secretly smash the teacher's car?"

Ye Huai'an smiled: "Okay, okay, don't make a mess, don't worry, I will clean up this kid in the future, I haven't eaten yet, right? ”

"Uh-huh!
