The manufacture of diesel engines was not so easy, and Wang Xika chose the V2 engine of the T34 tank during World War II. Although this engine is relatively simple compared to other tank engines, it is much more complicated than building a watt steam engine.

First of all, the steel needed to make the cylinder is difficult to produce, and secondly, the assembly of the engine needs to be precise, otherwise it is easy to "burst". In addition, the oil used for lubrication is not up to the task – even the diesel fuel used for fuel is difficult to refine without equipment.

Wang Xika was not an engine worker before the crossing, but relied on a little basic common sense of modern people to reproduce those relatively simple machinery. After doing it for a few days, Wang Xijia found that it was impossible for him and Carpenter Liu to complete such things as tank engines alone, even if he had mines and time, but he had no talents. At present, the most important thing is not to improve the manual skills of Liu carpenters, but to cultivate a group of talents.

Wang Xijia built a large room in the village as a classroom, and asked Carpenter Liu to get a flat piece of wood to use as a blackboard. Then the young people of the village and the few little hairy people who came with them were called out to attend classes, and some basic physics and mathematics were taught to them, and only two combat classes a week were held, and the rest was to learn the methods of various machines, and to learn the structure of airplanes, cannons, and tanks.

However, the children in the village are very naughty, and they can't sit still in class, except for martial arts classes, they are not interested at all. Wang Xijia thought that he could quickly impart scientific knowledge in ancient times, so that this era could achieve a technological explosion and quickly become the level before he crossed over. After working as a rural teacher for a few days, he found that he was thinking too much - after all, in the era before his crossing, not all places on the earth were technologically advanced, and some places on the earth were no different from the technological level of Hekou Village. Some people just aren't fit for education – at least not in Shanghekou village.

Just when Wang Xijia was about to give up the teaching profession, a student suddenly stood up: "Teacher, can you teach us literacy first, and then call us the laws of thermodynamics?"

Wang Xijia suddenly realized: it turned out that these students didn't know a word, and they couldn't read what board books they wrote, so they were naturally not interested.

Wang Xika looked at the student who asked him a question, he was not tall, he looked like he was 14 or 15 years old, but his eyes flashed with wisdom, and he was a material that could be made.

"Your question is very good, what is your name?" Wang Xika asked kindly

"Just teach me Ogura. Ogura said shyly.

"Very good, starting tomorrow, we will have a Chinese class first and teach everyone to read. ”

The effect of a literacy class is completely different from that of a math and physics class, and the students are very interested in reading and listening to stories. But Wang Xijia himself was impatient, he just felt too bored. It's like a king player, if you ask him to communicate with the players in the Diamond round, he can still communicate, but he doesn't have much to talk about with the bronze level players - you haven't started yet, how can you talk?

Wang Xijia gave a student a month of lessons, and he couldn't hold on anymore, it felt like a young parent tutoring a primary school student to do homework, except for anger or boredom. Wang Xika finally had enough, he made an excuse to say that the map he wanted to draw last time was not completed, and asked the students to review it by themselves.

As soon as he walked out of the classroom, Xiaocang stopped Wang Xijia and asked him to assign some homework. Ogura's studious and progressive spirit moved Wang Xika, so he spent a few days writing a set of simple textbooks for Ogura, including a literacy textbook with 3,000 Chinese characters, some basic laws of mathematics and physics, and a few weapon design drawings.

"Ogura, when the teacher goes out, you will be the study committee. Wang Xika taught the textbook he wrote to Ogura, and said in the tone of his high school homeroom teacher.

"What is a study committee?" asked Ogura innocently

"The study committee is that you study it yourself first, and then teach what you have learned to your classmates, are you willing?"

"I do!"

"Good!"

Wang Xika touched Xiao Cang's head with satisfaction, turned his head and ran.

He found Peng Lianhu and Lang Naduo, who went out together last time, and asked them if they would like to go out with him again and go to a farther place.

Peng Lianhu said that he didn't want to go far away, there were old and young people in the family, and he had to teach the children martial arts lessons, so he didn't go. also persuaded Wang Xika not to run around, can't he live in the village in peace?

"Brother, what do you want, our village will give you something, can't we keep you?" Peng Lianhu finally asked.

Wang Xijia vaguely heard the taste of a northern Shaanxi folk song from Peng Lianhu's tone, "Our village is such a good place, can't we keep you?" He knew that Peng Lianhu dragged his family and wandered around with him, so he no longer demanded it.

Zack fled with his people, and he was burdened with a blood feud, so it was naturally impossible for him to explore the world with him, so he stayed in the studio to study diesel engines. What Wang Xika didn't expect was that Lang Naduo didn't want to go out anymore, saying that he was living well in Shanghekou, playing football and herding sheep with nothing to do, and life was delicious.

Wang Xijia returned home with a stomach full of anger and packed his luggage alone-no matter what, he had to go to the beach, even if it was only himself! Halfway through packing, Meng Jianniang suddenly came over silently and dismantled Wang Xijia's burden.

"What are you doing? You don't want to go far away, don't stop me?" Wang Xika said angrily.

"Don't you want me to accompany you?" Meng Jianniang said as she put her luggage into Wang Xijia's baggage.

"They didn't go, and I thought you wouldn't either. Wang Xika's eyes were a little moist

"They are them, I am me. I will identify you, even if you go up the sword mountain and down the sea of fire, I will follow you, as long as you don't dislike it!" Meng Jianniang said firmly

Wang Xijia was so moved that no matter how ridiculous her thoughts were, this ancient woman had been silently supporting her. At a time when his friends were reluctant to follow him, only this woman followed him. What kind of friendship is this?

The appearance of his wife and children before the crossing seems to have been blurred, if he can't go back to the original era, then in this world, marrying Meng Jiaoniang shouldn't be considered unkind, right? I was 18 years old when I first came, and now I have to be 19 or 20 years old, and it's time to start a family. It's good to find a place with a good scenery on the road and get married to Meng Jiaoniang.

Because there were only two people going on the trip this time, Wang Xika didn't plan to drive the four-wheeled carriage anymore, he rode Xiaolan by himself, and let Meng Jiaoniang ride a horse.

The two came to Peach Blossom Town along the same road, this town was the same as when they first came, bustling with people coming and going, but there were no more white-haired and black-haired people who bought salt, which was emotional. Wang Xijia specially went to the casino to go around, trying to find the Yuan Qingniu who also crossed over, and the casino owner told Wang Xijia that Yuan Zhenren had just settled the rent for three days and left.

So he left Peach Blossom Town.

This time I didn't go to either the snowy mountains or the canyons.

Wang Xijia followed the river all the way to the east, he wanted to see the sea and explore the unknown world.
