Establishing an education system is much more difficult than fighting a war, and if a time-traveler wants to defeat the primitives, all he needs to do is build two modern weapons and build an airplane. Weapons and airplanes have been seen before Wang Xijia crosses, as long as the structure in his mind is copied. In the process of manufacturing firearms and airplanes, Wang Xijia also found helpers to help make some parts. But the helpers they found didn't know what the purpose of making those parts was, they just had to make those parts as they were and hand them over to Wang Xijia. As for the principle of what the bullet can produce so much energy, and why the plane can take off, it makes no sense to them. In their eyes, Wang Xika is like a fairy - what is the big deal with some powerful magic weapons of immortals?

Education is to let these ancient people know why bullets are so powerful, why airplanes can fly in the sky, we need to let them know the principles behind phenomena, and we need to instill their own knowledge into these ignorant minds.

Wang Xika hopes to select some smart young people first, teach them basic theories, and then let these young people teach children. It's a pity that people in this era are not interested in learning, and if it weren't for Wang Xijia's high prestige, basically no one would want to learn "those useless things". Among them, the two people who are most reluctant to learn, one is Peng Lianhu, and the other is Zack.

In fact, when Wang Xijia needed to find a teacher, Peng Lianhu was the first to sign up. Peng Lianhu opened a martial arts gym before competing with Wang Xijia, and usually "took students" to teach some boxing techniques invented by himself, and felt that he had rich experience in education. However, this person's brain is not naturally suitable for accepting scientific culture, and Wang Xijia told him about Newton's three laws. Peng Lianhu was particularly unable to understand Newton's third law: the force and reaction force between two objects are always equal in magnitude and opposite in direction, acting in a straight line.

This law is something that students must master around the second year of junior high school, but Peng Lianhu obviously has his own understanding of the concepts of "interaction", "between two objects", and "action and reaction force".

"Master, the two of us are lifelong friends, and there is a sentence I don't know whether to say or not. After Wang Xijia explained this law to Peng Lianhu, Peng Lianhu found Wang Xijia seriously.

"What's the matter, tell me. It was the first time Wang Xijia saw Peng Lianhu so serious, and he was a little nervous. I don't know what big things this first brother to make friends after crossing over has anything to say - he is already ready in his heart, as long as he doesn't let Wang Xijia give him his wife and children, he can agree to anything.

"Then I'll just say that you're harming students by teaching so badly. Peng Lianhu obviously made a lot of determination, and added: "You just want to beat me, and I still say so."

Wang Xika breathed a sigh of relief, it seems that this guy doesn't want to dig into his own corner, it turns out to be a scientific thing. At first, Wang Xijia thought that Peng Lianhu had taken care of Meng Jianniang for a period of time and had feelings for her.

"Tell me, why am I talking nonsense?" asked Wang Xijia

"You say that the forces of action and reaction are always the same when two objects are always the same, which is a complete fabrication. I punched Zack, this is my force, then Zack punched me, it was his reaction force, how can this be the same? Look at Zakra's bow, how strong is he?

Wang Xika was angry and funny, thinking that he didn't understand, and told Peng Lianhu for a long time what is called interaction, what is between two objects, he said: "You punch Zack and Zack punch you is not action and reaction force, for example, if you punch Zack on the head, your fist has a force on his head, and his head also has a force on your fist, these two forces are of the same magnitude and opposite directions, this is the force and the reaction force." After saying that, he felt that it was a bit inappropriate to use this example, so he gave another example: "For example, if you punch the wall, the wall will be subjected to a force, and at the same time, your hand will also hurt, this is the reaction force exerted by the wall on you, and these two forces are equal, do you understand?"

Peng Lianhu suddenly clenched his fist and punched the wall, and immediately punched the wall: "Master, I punched a hole in the wall, why didn't the wall knock me out?"

Wang Xijia burst into tears and said: "Lianhu, it's the master who is not good, you don't have to participate in the study in the future, this knowledge is really useless to you." He understands that some people are really not suitable for studying, and there is no doubt that Peng Lianhu is such a person.

Peng Lianhu said: "No! You said that you want to engage in education, you need teachers, I have taken students, I will be a good teacher, I don't believe you ask my students." I just can't talk nonsense to students. ”

Wang Xika was silent, he felt that his train of thought was messed up by Peng Lianhu. There are often all kinds of problems in life, and escaping is not the way, only by facing these problems can you become strong. Now Wang Xijia has encountered such a problem, and he needs to find a way to solve it, neither offending his brothers nor delaying his students.

After thinking for a long time, Wang Xijia said: "Lianhu, I really need a talent like you to pass on your skills." Are you willing to teach students how to cook? You're the best cook in the world, and I don't want your skills to be lost. ”

When Peng Lianhu saw Wang Xijia praising him, he couldn't hide the joy in his heart and said: "Okay! But I don't dare to guarantee that the students I teach cook as delicious as I do—cooking requires talent, and talent can't be taught!"

Wang Xijia sent Peng Lianhu out of the house and decided to find an opportunity to get Peng Lianhu a chef school to better play this brother's talent. As soon as Peng Lianhu went out on the front foot, Zach came in on the back foot.

"Zack, what's the matter?" Wang Xijia has a good impression of Zack, a smart hairy man.

"Brother, you have saved the lives of our people, and our mountain people are willing to swear to serve you. Zach said.

"Don't talk to the family, why are you seeing the outside world like this?" asked Wang Xijia.

Zach didn't answer and continued, "But I want you to respect the customs of our people, and I don't want them to lose their traditions. ”

"Tell me, if anyone doesn't respect the customs and habits of the Mao people, I'll clean him up!" Wang Xika said angrily, he knew that no matter what era, the racial issue was a big problem, and he would not allow racial discrimination to happen in his jurisdiction. After the battle between Qiuqiu and the craftsman, Zach brought back a dozen little hairy people from the snowy mountains, and now goes to school with children from other clans in Wang Xijia. Could it be that some classmates are ignorant and bully the little hairy man?

"To tell you the truth, the person who does not respect our customs is the benefactor you. Zach looked into Wang Xijia's eyes and said calmly.

"Ah, tell me how I don't respect your customs, maybe I didn't pay attention, and I will definitely change it in the future. Wang Xijia said sincerely. He has been dealing with the Maoren for a long time, and he doesn't know where the Maoist taboo has been committed.

"You say that the world is made up of two things, molecules and atoms, which is different from our tradition. In our tradition, the world is made up of four substances: wind, fire, water, and earth, not the two you say. If a hairy person doesn't know the wind, fire, water and soil, then he can't be regarded as a hairy person. Zach said

It turned out that this brother also had a disagreement with Wang Xika because of scientific issues, I remember that when he was engaged in the engine, Zach had a disagreement with Wang Xijia because of the three laws of thermodynamics, and he and Carpenter Liu went to Wang Xika to take the blame, but I didn't expect that this time there was a disagreement because of the periodic table. Wang Xijia popularized the periodic table with Zach and told him that there are not only four elements in the world. He also told him that in their traditional culture, the world is composed of five elements: "wood, fire, earth, metal, and water", commonly known as the five elements. There is no contradiction between learning traditional culture and learning science, and learning from yourself will not make the Mao people lose their traditions.

Zack quietly listened to Wang Xijia's words, and said, "I think that Five Elements Theory is still a bit interesting, a bit similar to our theory. As for the periodic table, I haven't looked at these things, I don't believe it. "Do you believe me?" Wang Xika asked, looking into Zack's eyes.

"I believe that even if you tell me to die, I will do it. I'm just telling you some of my thoughts, and if you're not happy, then I won't talk about it later. Zach also looked into Wang Xika's eyes and replied.

"Okay, if you believe me, I'm done, I promise you, I won't let the Maoists lose their traditions, and I also want to ask you to educate these Maoist children about their traditions. If you want, be the traditional teacher of these Mao, teach them your knowledge, teach them archery. But also let these children come to me to school, and learn both kinds of knowledge, it's good for them, okay?" Wang Xijia understood that Zach was also like Peng Lianhu, and it was difficult for these adult primitives to accept modern knowledge.

He placed Zach as a physical education teacher and taught the students to exercise.

Another good brother, Lang Naduo, has a brain similar to that of Zach and Peng Lianhu, and is very resistant to modern science that he has not been exposed to. He always believed that the earth was flat, and that it was carried on a large tortoise, as it was traditionally known to their werewolf clan. Lang Naduo was very reluctant to believe that he lived on a round planet called Earth, and almost fell out with Wang Xijia because of this matter.

Wang Xijia is easy to talk about, and finally arranged Lang Naduo as a language teacher, because although this guy is not very good at brains, he can speak several languages, can understand animal speech, and is very good at playing football. As long as he can teach these things to the children, that's fine.

As for the heavy burden of teaching scientific knowledge, it seems that I can only pick it up first.
