Jiang Yu opened his mouth, looked at Er Shi sitting next to him, and said in disbelief: "Er Shi, is this the meal you went to fetch?"

Er Shi nodded.

Jiang Yu felt that it was very mysterious. He suddenly remembered something and asked hurriedly: "Did you give me a meal ticket?" But don't threaten the aunt in the cafeteria...

Ershi nodded again and pointed to the small wooden box on the table, where Jiang Yu usually kept his meal tickets.

Jiang Yu: How can I break the sudden feeling that "my family has a baby who has just grown up"...

But this feeling disappeared after breakfast, Ershi insisted on washing the dishes, and then successfully dropped the bowl until only one was left.

After soothing the bewildered Er Shi, Jiang Yu accepted his fate and picked up the pieces.

Forget it, don’t ask too much, at least you are recovering slowly, right?

Hmm... In this case, maybe when Jiang Yao and Shi Xiaoxin come back, the two Shi brothers can recognize each other...

After cleaning up, he found that Paipai was not there, so he ran back to the mountains to see his babies. Jiang Yu took Ershi to Qinglong Village.

This morning, she and Zhou Shen made an appointment to visit the bay.

By the way, you can also take a look at the preparation work for drying salt and how it is done.

At this moment, the village has begun to become lively...

Lin Dahe carried the hoe and walked to the fields. This was what he had to do every day.

After the grain is planted, it is not allowed to grow on its own. You need to check whether the water in the paddy field is too much or too little, and then dig out or block the water outlet in time. You also need to clean up the weeds and check the growth of the rice.

Condition……

There are so many things to do!

Mrs. Zhou, Yu Zhen and Xiao Shitou's mother walked to the river together, holding the wooden basin filled with clothes against their waists. They held the wooden basin with one hand and greeted the villagers passing by with the other.

Zhao Liu stayed at home to take care of the children.

The fourth aunt was in the courtyard, watering, fertilizing, and removing insects from the vegetable patch in front of the house. She couldn't stop smiling as she watched the vegetables gradually grow.

After feeding the chickens in the chicken coop, Mrs. Sun was sweeping the yard with a broom...

The drying yard was also under construction as usual, and many villagers carefully walked down the slope carrying stone slabs.

Jiang Yu's eyes fell on the villagers picking up the stone slabs, thoughtfully...

When Jiang Yu and Er Shi arrived at Qinglong Village, Zhou Shen was already waiting for her at the entrance of Qinglong Village, carrying a backpack behind him.

Because it takes three hours to walk to the bay, Zhou Shen has become accustomed to bringing some dry food and water every time he goes.

The road from the back of Qinglong Village to the bay has been smoothed out.

As Jiang Yu walked, he chatted with Zhou Shen about the school. The two chatted happily.

Er Shi listened silently to the two men's conversation, showing a thoughtful expression from time to time.

What Jiang Yu didn't know was that Ershi was constantly enriching the blank areas in his mind through observation and listening...

At noon, the three of them arrived at the cave in the bay.

Because of the long distance, villagers who come to work here usually set off at dawn.

At this time, I was already preparing lunch. When I saw them coming, I greeted them warmly.

Jiang Yu and the others had already eaten dry food on the way, so they declined the villagers' kindness and went to the elevator to check.

The entire elevator has been completely set up, and it matches the drawings they drew before. It can be seen that they work very carefully, and Zhou Shen supervises it very well. Jiang Yu even checked it carefully with a perspective, but found nothing.

what is the problem.

Finding nothing, Jiang Yu decided to give it a try himself.

There are four pedal positions in total. After the villagers finished eating, Jiang Yu personally stood at one of the positions, holding on to the handrail, and stepped on the pedals with the villagers.

Jiang Yu stepped on the pedals vigorously while observing the operation of the elevator, using perspective to check the movements of various parts...

There is nothing wrong with the parts, but even if four people work together, it is already very laborious just to move the empty car up and down.

It is conceivable that if there are people in the car, or even if cargo is transported in the future, four people will not be able to step on it at all.

After trying it himself, Jiang Yu probably knew where the problem was...

In order to ensure that the car is strong enough, the wood used to make the car is Qinggang. The wood is hard and has high density, so it is naturally heavy in weight.

In addition, some of the accessories they bought from the mall are not light, resulting in the current car being too heavy...

But how to solve this problem is a bit difficult. After all, the car is already ready and cannot be dismantled and redone. What's more, it is impossible to ignore quality in order to reduce weight.

So we still have to start with how to save effort...

Zhou Shen saw Jiang Yu deep in thought, so he did not disturb her and walked towards the villagers who were working...

The bottom of the cave is very large, with an elevator in the middle and a boiler for purifying salt around it.

As for the early drying and burning of coarse salt, which requires a large space, it is done outside the cave.

The boiler in the cave has been set up halfway, and the villagers are chatting while working.

When Zhou Shen walked over, another villager from Qinglong Village asked him, "Second Master, I heard that a python entered the village yesterday. Did you see it?"

Since they came here to build a village, both Long Hai and Zhou Shen have actually enjoyed this ordinary life.

That's why Long Hai insisted on changing Qinglong Gang to Qinglong Village. According to him, "Qinglong Gang doesn't sound like the name of a serious village."

They also asked the villagers to change the head of the family to the village chief, so Long Hai became the chief village chief, and Zhou Shen became the second village chief...

Although Zhou Shen also agreed to change his name and title, the title of Second Village Chief was somehow awkward...

However, Long Hai insisted and he accepted it.

After all, he is also a teacher in the village school now, so he still has to have a serious title, just like Jiang Yu said, he is a role model for others.

It's just that many people in Qinglong Village are still used to the previous names. Every time he hears them call him the second master, Zhou Shen feels like he's been brought back to his original form...

At this moment, Zhou Shen could sigh in his heart, and while rolling up his sleeves to help, he chatted with them one after another...

On the other side, Jiang Yu was sitting on a small stool, holding his chin with one hand, thinking about how to save effort. Hearing them talking about yesterday's events, he suddenly felt blessed...

He quickly put his hand into his bag, took out a pen and paper from the space, and drew two stress models with just a few strokes...

One is for vertical lifting, and the other is on an incline.

While Jiang Yu was drawing the force analysis, he was mumbling something...

"When lifting vertically, the pulling force is equal to the gravity... Well... the friction of the pulley may also be added...

When on an incline, part of the gravity is taken away by the support force of the incline...so the pulling force is equal to part of the gravity plus the friction of the incline...

Then, when the angle of the incline is smaller, the more part of the gravity is divided by the supporting force...

That is to say, the smaller the angle of the bevel, the less effort you have!

In this way, as long as you find a way to reduce the friction, that's it!

But in this way, the track will become longer...well...you have to find a suitable angle."

Thinking of this, Jiang Yu took out a soft ruler and measured the data in the cave. He stopped from time to time and calculated something on the paper...

Zhou Shen noticed the movement on her side and came over to take a look curiously...

Zhou Shen saw some crooked characters drawn under the two pictures, and Zhou Shen was confused.

Unconsciously, I remembered that I accidentally heard the villagers in Yunlai Village say that the Jiang brothers and sisters were gods...
