Jiang Yu opened his mouth, looked at Ershi who was sitting next to him, and said in disbelief: "Ershi, is this the meal you went to eat?" ”

Nishi nodded.

Jiang Yu felt very mysterious, suddenly remembered something, and hurriedly asked, "Did you give a meal ticket?" "But don't be a threat to the canteen......

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

Jiang Yu: Suddenly, there is a feeling of "my family has a child who has just grown up", how can it be broken......

It's just that this feeling disappeared after eating breakfast, Ershi insisted on washing the dishes, and then successfully smashed the bowls to only one.

After appeasing the helpless Ershi, Jiang Yu resigned himself to cleaning up the fragments.

Forget it, don't be too demanding, it's slowly recovering, isn't it?

Well...... In this way, maybe when Jiang Yao and Shi Xiaoxin come back, Ershi will be able to recognize the Shi family brothers and sisters......

After cleaning up, he found that Pai Pai was not there, and he wanted to come and run back to the mountains to see its treasures, so Jiang Yu took Ershi to Qinglong Village.

This morning, she and Zhou Shen made an appointment to go to the other side of the bay to have a look.

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

By this time the village had already begun to come alive......

Lin Dahe carried the hoe and walked to the field, which was what he had to do every day.

After the grain is planted, it is not left to grow on its own, it is necessary to see if there is more or less water in the paddy field, and then dig up the water outlet in time, or plug it, and clean up the weeds to check the growth of the rice......

There's a lot going on!

Mrs. Zhou, Yu Zhen and Xiaoshi's mother walked to the river together, the wooden basin full of clothes was pressed against their waists, holding the wooden basin with one hand, and greeting the villagers with the other.

Zhao Liu stayed at home with the children.

The fourth aunt watered, fertilized, and removed insects in the vegetable patch in front of the house in the courtyard, and watched the vegetables gradually grow, and her face couldn't stop laughing.

After Mrs. Sun finished feeding the chickens in the chicken coop, she took a broom and swept the yard......

The drying ground also started as usual, and many villagers carried stone slabs and walked down the slope carefully.

Jiang Yu's gaze fell on the villagers who were picking up the stone slabs, thoughtful......

When Jiang Yu and Er Shi came to Qinglong Village, Zhou Shen was already waiting for her at the entrance of Qinglong Village, with 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 repaired very smoothly.

Jiang Yu chatted with Zhou Shen about the school as he walked, and the two talked happily.

Ershi listened silently to the two of them on the side, showing a thoughtful expression from time to time.

What Jiang Yu didn't know was that Ershi was constantly enriching the blank areas of his mind by observing and listening......

At noon, the trio arrived at a cave in the bay.

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

At this time, lunch was already being prepared, and when I saw them coming, I greeted them warmly.

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

The entire elevator has been completely erectioned, which is very consistent with the drawings they drew before, it can be seen that they are very meticulous in their work, and Zhou Shen's supervision is also in place, Jiang Yu even carefully checked it with perspective, and did not find any problems.

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

There are a total of four positions of the foot pedal, and when the villagers finished eating, Jiang Yu personally stood in one of the positions, holding the handrail, and stepped on the foot pedal with the villagers.

Jiang Yu pressed the pedal vigorously while observing the operation of the elevator and viewing the activities of various parts with perspective......

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

It is conceivable that if there were people in the car, or even later to transport goods, four people would not be able to step on it at all.

After trying it himself, Jiang Yu probably knew what 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, the density is high, and the natural weight is not light.

In addition, some of the accessories they bought from the mall are not light, resulting in the weight of today's car......

It's just that how to solve this problem is a bit difficult, after all, the car has been done, and it can't be dismantled and redone, not to mention, it is impossible to reduce weight without considering quality.

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

Zhou Shen saw that Jiang Yu was pondering, so he didn't bother her, and walked towards the villagers who were working......

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

As for the drying and firing of coarse salt in the early stage, the site required is larger, and it is carried out outside the cave.

The boiler in the cave is halfway built, and the villagers are chatting as they work.

When Zhou Shen walked over, a villager from Qinglong Village asked him, "Second master, I heard that there was a python in the village yesterday, did you see it?" ”

Since coming here to build a village, whether it is Longhai or Zhou Shen, they actually enjoy this ordinary life.

That's why Long Haicai insisted on changing the Qinglong Gang to Qinglong Village, according to him: "The Qinglong Gang doesn't sound like a serious village name. ”

also asked the villagers to change the head of the house to the village head, so Long Hai became the big village head, and Zhou Shen was the second village head......

Although Zhou Shen also agreed to change his name and title, the title of the second village chief is unspeakably awkward......

However, Long Hai insisted, and he also admitted it.

After all, he is also a gentleman in the village now, and he still has to have a serious title, just like Jiang Yu said, to be a teacher.

It's just that in Qinglong Village, many people are still used to the previous titles, and every time I hear them call themselves the second master, Zhou Shen has a feeling of being beaten back to his original form......

At this time, Zhou Shen was also able to sigh in his heart, and while rolling up his sleeves to help, he chatted with them with a match......

On the other side, Jiang Yu sat on a small stool, holding his chin in one hand, thinking about how to save effort, listening to them talking about yesterday's events, and suddenly his soul was blessed......

Quickly put his hand into the satchel, took out a pen and paper from the space, and drew two models of force with a few random strokes......

One is vertically lifted and the other is on an inclined plane.

Jiang Yu was drawing a force analysis, and at the same time reciting words......

"When lifting vertically, the pulling force is equal to the gravitational force...... Well...... You may also want to add the friction of the pulley......

When on an inclined plane, the gravitational force is partially divided by the supporting force of the inclined plane...... So the tensile force is equal to a part of the gravitational force plus the frictional force of the inclined plane......

Then, the smaller the angle of the inclined plane, the more the gravity is divided by the supporting force......

That is, the smaller the angle of the bevel, the less effort it has!

That way, just find a way to make the friction smaller, and you're good to go!

It's just that in this way, the orbit will become longer...... Well...... You have to find the right angle. ”

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

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

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

I unconsciously remembered in my mind that I accidentally heard the villagers of Yunlai Village say that the Jiang family brothers and sisters are immortals......

Zhou Shen couldn't help but think: Isn't this drawing a talisman? ? There is no yellow paper or cinnabar, no matter how you look at it, it is different from the rune paper he has seen before......
