The brigade began to set off again.

On the busy road, the weaving group was busy weaving curtains all the way, the female red group was constantly busy adding masks, and the old guys in charge of the spoon group experienced the beauty of not worrying about meat for the first time.

Hua Tian and Sister Jinghua were accompanied by "You can't do it, you can't do it!" In the slogan, there is a rhythmic addition of material packages.

In other words, even if you are tired, you have to be happy.

Otherwise, how boring is this kind of work that only needs to be done by machines in modern times when it is done by hand?!

Belch? That's right! How did she not think that this kind of single-procedure work could be completely completed by the mechanism, using levers and hammers, the animal would generate a pull force with every step, which was a little similar to the principle of stone grinding.

The stone mill is to rotate the gear, and the action of the hammer only needs to be unloaded when it stops, and the force that rushes down through gravity completes the thrashing action, and when the lever is tightened when walking, the thrashed end is pulled up again. This is the same as the seesaw of the little pot friend.

Make this guy and you'll be able to keep your hands free perfectly! Hey, hey, she's such a clever little ghost.

"Sister, do you know why people are smarter than livestock?" Hua Tian turned his head and asked Hua Jinghua next to him.

Jinghua didn't understand what Hanada's sudden request was for, so she shook her head cooperatively.

"Of course, it's because people use tools! I have to draw a tool for the next few cows, and ask my uncle to help me type them. Hanada said.

"Why are there only cows and cows, not horses and mules and donkeys?" Hua Jinghua didn't understand.

"Only the cattle and cattle like to move and stop, and the mules, horses, and donkeys are constantly moving forward, I need a buffer to pull back the time, otherwise the gravity is not enough." Hanada said a few strange words, but when combined into one sentence, Jinghua understood.

Even Jinghua herself felt strange, how could she understand?

"Are you saying that Niu Niu can stop and go, and with the tools you said, we can complete this work? Jinghua asked.

"Yes! Sister, you wait. Hanada stood up and was about to leave.

Hua Jinghua grabbed her, "If you want Niu Niu to work, will it delay the trip?" You know, we can't afford to delay. ”

"The reason why he picked Niu Niu is because his walking habit is like this, and after we replenish the warehouse this time, the car is full again, and the rush is like this, but whether it is delayed or not, it is better to try it first. In case of delay, we will continue to lick. "Huatian doesn't have a packing ticket, so you still have to try, even Uncle Dong knows that practice makes true knowledge.

Hua Tian drew out the simple tools and told Uncle Hua to make one out and practice it first, and if it was feasible, then add one to each cow cow, so that the package could be delivered on time.

She wrapped each bag in gauze in advance, and when she sold it, it was also wrapped in gauze, so that even if she took it apart and studied it, it would be a pile of powder. She also thought about using lotus leaf buns, but the whole packet of stewed boiled food will fall apart.

The excess can also be tuned, and she did not sign the terms of the contract with Tianxianglou, so she didn't worry about selling the extra one.

So Uncle Hua made a thrashing tool.

It's just that the weight of the hammer Hanada has to be experimented with. To match their ten-centimeter-square stone basin, the hammer fell with such force that it smashed the spices. But you can't smash the stone basin. This is a proposition that needs to be calculated repeatedly, because she did not measure the habit and time of Niu Niu to stop and go.

This physics problem was handed over to the flowers and plants. "You will come. I figured it out. ”

It is known that the maximum degree of the lever is 0.98 meters, the weight of the stone basin is 8 catties, and the speed at which the hammer falls to the bottom is 0.1 second.

The weight of the hammer should be less than a few.

"It's less than eight taels, but I suggest that the plane of the hammer should be made larger, so that the stone basin can be evenly stressed." Hua Cao'er suggested.

"I originally designed the height according to Newton's theorem, so I can do the math. So we're both fast. ”

Hanada shrugged, it would be ridiculous if it would stump the grass.

"Sister, I have seen it, an extra nine catties will not delay Niu Niu, we can all rest assured. I'll ask my uncle to make a few more for the rest of the cows. Hanada and Jinghua said.

"So that we can save energy to do other work, I will help my mother, my mother is still there, she is tired. Children who are not filial will be said. Hua Jinghua said.

"Sister, as long as you work hard, anyone can see your filial piety to grandma, who dares to say that you can't do it? But the gang still needs to help, and it is appropriate to lighten the burden on the milk. Hanada smiled and waved at Jinghua.

Hanada observed the cows behind him again, and saw that it was really not delayed, so he put his mind at ease.

Thinking of the filial piety that my sister just mentioned, my mother is now pregnant with grass, and smelling tung oil is not good for my health.

So Hanada also rushed to help her mother.

Cai Xuefen waved her hand, "It's okay, everyone understands that my mother is a double body, and I didn't let my mother do the work of brushing tung oil." The work of locking the edge is also taught to them by your aunt, and the mother just moves her mouth without effort. ”

In this way, you are an embroidery layman, you usually sew buttons or something, and you also teach other people's women to be popular, which shows how wasteful your brain is.

It is the layman who looks at the excitement, and the insider who looks at the doorway.

It is all up to imagination for a layman to interfere with an insider's business.

That is, the name of Cai Xuefen's original master embroidery frightened the people of the female red group, and felt that everything her mother said was right.

But it's hard to be a mother, and that's really right.

The first batch of masks made in a hurry were first brought to all employees, and then put on the protective clothing that had been done before.

Just like the people who volunteered in their previous lives, they tried to drink less water and go to the toilet less every day, and they also had to walk hard in airtight white clothes.

You must protect yourself first, so as not to tire yourself and others.

The work of adding masks is still being completed. Those who promised to be too conservative did not dare not do it.

On this day, passing through the dense forest, there were some people on the left and right who were coughing or with white lips.

There are more than sixty people, to say the least. Are they not afraid of wild beasts in the forest?

Hua Tian and Cai Xuefen looked at each other, "Mother, I guess it's going to be bad." The master's dream is about to come true again. But we've all avoided Jinhai City and left? Hanada was puzzled.

"Silly girl, you don't know the transmission habits of the virus, it has an incubation period, and it is not impossible to go their separate ways after infection, there is only one road ahead, but when you get here, there are many forks in the road. You don't understand this? Cai Xuefen touched the head of the flower field and looked at the little flower field lovingly.

"I almost forgot, are we going to walk faster, rush through the crowd or help them?" Hanada asked again.

"You and your father's identity is different, your father has a heavy responsibility on his shoulders, he wants to keep not only our family, don't blame your father for being ruthless, I think if I guess well, your father will not choose to help them selflessly." Cai Xuefen said her understanding of her husband.
