Seeing Xiao Gengwu writing and drawing, Yao Tongjia did not disturb him. She first started a fire to boil water, and then put the soapberry leaves into the water to wash them.

After washing, the soapberry leaves were put into a large pot to boil. The leaves shrank immediately when they came into contact with hot water. Yao Tongjia put all the leaves into the hot water to boil in several batches.

By repeating this process continuously, all the leaves from half a yard only need to be cooked in one big pot!

The water quickly boiled, and as it boiled, the liquid became increasingly viscous. Yao Tongjia carried the rows of wooden compartments she had prepared to the kitchen and poured the hot liquid into each compartment.

When Yao Tongjia finished making the soap, put it in the yard to dry, and brought it into the room, Xiao Gengwu stood up and said, "I'll make soap with you!"

Yao Tongjia: "......" Your time arc is too long!

What are you drawing?

Seeing Yao Tongjia change the subject, Xiao Gengwu guessed that he must have missed something again, so he could only follow her lead: "I just disassembled the tractor and found that there are some things that can be improved inside!"

Xiao Gengwu handed his drawing to Yao Tongjia. Yao Tongjia saw that it was a floor plan. As a layman, she could only look on with interest: "What are the good aspects after the improvements?"

"Much less fuel consumption, more power!"

"That's amazing?"

You should know that low fuel consumption and strong power are topics that many companies have been researching in later generations, but this guy just disassembled a tractor and made it by writing and drawing some notes.

"What have you changed? You need to understand that even changing a single screw is a major overhaul. There's no guarantee anyone will buy your blueprints!"

Xiao Gengwu didn't care: "Some parts will definitely need to be changed. I just designed it based on my own calculations. We'll only know what it will look like after it's made!"

"I'd be even happier if I could make it and test it, but it's okay if I can't. There will always be another chance in the future. The only loss is a little time!"

"I wanted to make soap with you, but you didn't even call me?!"

"I see you're concentrating on your work, and I didn't want to disturb you!"

"If you need anything in the future, just call me. My matters aren't urgent. You've seen this; even if I draw up the blueprints, it might not be of any use!"

Xiao Gengwu looked at the blueprints in his hand: "Let's go to the tractor factory another day!" He still wanted to know if what he had drawn was just theoretical.

He disassembled the tractor today and felt his blood boiling. The things he likes are machinery, machines, and cold things, not wood!

Once he set a goal, he would pursue it. He was certain that he would achieve success in the field of mechanics. The young Xiao Gengwu firmly believed in his mind!

Just then, the village chief and the brigade leader arrived with some things. Yao Tongjia opened the door and let them in, asking curiously, "What are you doing with two or three bags of things?"

"These two or three bags are all wheat. Consider them a reward for Xiao boy. Thank you for fixing our tractor. Otherwise, if we had called those bastards back to fix it, they might not have been able to fix it for us!"

The village chief thought that the screws that had been removed and replaced earlier could still be used after being reinstalled, but the screws that had been replaced earlier were broken. Those people really had no heart at all.

Every time I come to get it repaired, it's never enough, unlike Xiao Xiao who fixes it and comes back without saying a word!

However, since the child is so good, they can't pretend they don't know. They still have to send what they need to send. They live in the county and what they lack most is food, so sending fine grains is the best option!

Hearing that it was wheat, Yao Tongjia was also happy. Who would want to eat black steamed buns when they could have fine grains to eat? She said happily, "Thank you, village chief and brigade leader. Or should we still pay you?"

"No need, no need. The previous group of people came and took more than this amount of food and gifts. We can't take advantage of you because you're young. But, Xiao, could you teach the tractor driver your car repair skills?"

The village chief spoke these words cautiously, because every time things went wrong, it was torture, and he really didn't want to deal with that group of people anymore. Xiao Xiao usually stayed in the county.

Xiao Gengwu nodded: "Yes, I can teach you!"

These words made the village chief unusually lively; the old man jumped three feet high in the air: "Young Xiao, really? That's great!"

Xiao Gengwu made the following request: "Find someone smarter. I will only teach them three times. If they don't understand after three times, I will not teach them again!"

Xiao Gengwu's least favorite thing to do is repeat the same thing. He teaches it three times, which is already his limit.

The village chief and the brigade leader quickly agreed: "Yes, yes, I'll go find someone right now and bring it to you right away!"

Yao Tongjia still refused: "Let's just tell them to go to where the tractors are parked. They need a tractor to teach, right?"

Actually, Yao Tongjia didn't really like just anyone coming to her door. The village chief and the brigade leader didn't object either. Repairing the tractor did require a tractor!

Seeing that the person had left, Xiao Gengwu asked with a smile, "You don't like people coming to our courtyard?"

Yao Tongjia nodded: "To be precise, I don't really like unfamiliar people coming to our yard! Do you think my idea is bad?"

"How could that be? What's wrong with not letting people come if they don't like it!"

The village chief and the brigade leader were really anxious. Less than half an hour later, they sent a child to call them over. Yao Tongjia checked the soapberry liquid and, finding no problems, followed Xiao Gengwu out.

They called a total of ten men, including the tractor driver. The youngest was fifteen years old, and the oldest, like the tractor driver, was almost thirty.

At this moment, everyone looked at Xiao Gengwu with shining eyes. In this turbulent era, anyone with even a little talent was criticized and persecuted, and talent was dwindling.

Now that Xiao Geng is willing to teach them car repair skills, he is truly a second parent to them in the countryside!

The village chief and the brigade leader said to the ten people, "From now on, call Xiao boy 'Master' and be sure to respect him!"

Everyone shouted, "Master!" The loud voices almost shattered Yao Tongjia's eardrums.

Everyone here is older than Xiao Gengwu, so how can they call him that?

Yao Tongjia also took a closer look at their faces and found that they were genuinely calling out, without any attempt to suppress their laughter.

It's true that people in rural areas of this era still respect their masters more, excluding those who criticize them from outside.

Without uttering a single wasted word, Xiao Gengwu took his tools and disassembled the car again, this time taking apart the entire engine, which terrified the village chief and the brigade leader.

What if we can't put it back together?

It was obvious that Xiao Gengwu knew what was going on. He first disassembled the tractor and explained the purpose of each part, as well as what would happen if it broke.

After saying that, he put the parts back together one by one. Some of the ten people immediately understood, while others did not.
