Li Changping couldn't help but be stunned for a moment after hearing He Yuyu's words. Although he was surprised, he quickly came to his senses and said first: "Yu Yu, please drink some water first, and I'll get you something to eat."

After Li Changping finished speaking, he stood up and headed towards his kitchen.

Although Li Changping cooks in a small world, it does not mean that Li Changping no longer cooks in the courtyard. After all, he is alone and does not go out. It is too conspicuous to cook without cooking every day. However, Li Changping can only cook at most.

Just boil some cabbage into paste, but Li Changping no longer eats it in his room. After all, he has built a wooden house in his own small world through his own efforts. It has everything in it, and he can freely eat meat and so on.

After finishing, I was able to wash the pots and pans with just one thought.

It is precisely because of this that Li Changping's room was a little mushy and there was some fried cabbage. However, seeing He Yuyu's appearance now, he was obviously very hungry, otherwise he would not have come to his house to ask for food.<

/p>

And because Li Changping knew very well that He Yuzhu was very hungry now, but He Yuzhu often brought leftovers from the canteen before, and there was no shortage of oil and water in his stomach. Therefore, Li Changping also wanted to get some meat for He Yuzhu.

When he came to the kitchen, Li Changping sensed that He Yuyu was drinking water. With a thought, he entered the small world. In the small world, he held a piece of braised pork head in his hand, and then came out.

In a small world.

Soon, the sound of cooking could be heard in the kitchen, and along with the sound came a strong fragrance of cabbage.

More than ten minutes later, Li Changping shouted: "Yu Yu, come to eat."

"Here we come, Brother Changping." He Yuyu's voice, which should have been crisp, was also mixed with a hint of hoarseness.

When He Yuyu came to the room where Li Changping usually ate, he saw a pot of paste on the table, four white-flour buns, a plate of cabbage, and a plate of pork head meat.

"Brother Changping!"

When He Yuyu saw the things on the table, his eyes turned red, and he looked at Li Changping and said.

"Okay, let's eat quickly, otherwise it will get cold."

Li Changping looked at He Yuyu and then said.

"Well, thank you, Brother Changping."

The throat in the middle of He Yuyu's white neck moved slightly, then he said something, then hurriedly sat down and served himself a bowl of porridge.

Li Changping saw He Yuyu's actions, smiled slightly, and returned to his room.

When Li Changping returned to the house, he first looked at the room where he ate, and then at the direction of the central courtyard. He ignored everything else and began to lie on the table and draw a sketch.

The oil pumping machine was also called the kowtow machine in later generations.

The pumping unit designed by Li Changping is a beam-type pumping unit commonly used in later generations.

Beam-type pumping unit, also known as beam-type pumping unit, beam-type crank-balanced pumping unit, refers to a pumping unit that contains a beam, is reversed through a connecting rod mechanism, and is balanced by a crank weight.

Rod oil production equipment.

However, Li Changping was not a professional in his previous life. In this life, he knew the system because he had it. Therefore, Li Changping designed it based on the photos he had seen in his previous life and the mechanical principles.

The beam pumping unit is mainly composed of a donkey head, a beam, a connecting rod, a crank mechanism, a reduction gearbox, power equipment and auxiliary equipment.

When working, the rotation of the motor is transformed into the up and down movement of the donkey's head through the gearbox and the crank-link mechanism. The donkey's head passes through the polished rod and the sucker rod drives the plunger of the downhole oil pump to move up and down, thereby continuously pumping the crude oil out of the wellbore.

.

It seemed very simple when he thought about it, but when he actually did it, Li Changping realized that it was really troublesome.

Time is slipping away bit by bit, and Li Changping is also drawing one draft after another.

Until He Yuyu walked out of the house next to him.

He Yuyu had just finished eating, cleaned up the dishes, and walked into the room where Li Changping was. He didn't see what Li Changping was doing, so he first said: "Thank you, Brother Changping."

He Yuyu's sudden voice startled Li Changping. When Li Changping looked up and saw He Yuyu, he remembered that He Yuyu had come to his house for dinner.

Li Changping waved his hand first, then began to clean up the messy scraps of paper he had thrown away, while saying: "It's okay, it's just a meal.

But Brother Zhuzhu, didn’t he cook for you?”

When He Yuyu heard Li Changping's question, he couldn't help but fell silent, lowered his head, and stood aside without speaking.

When Li Changping saw He Yuyu's appearance, he first picked up the draft papers that fell on the ground, then put them aside, and then said: "What's wrong?

Did you quarrel with your brother?"

"No, there was no quarrel."

He Yuyu said dullly.

"Then what's going on?

Judging from your face, it seems like you haven't eaten for several meals. What's going on? Tell Brother Changping." Li Changping stood up straight and looked at He Yuyu with a serious face and asked.

He Yuyu was silent for a moment, and then said: "My brother gave the lunch box he brought back from the cafeteria and the food at home to the Jia family. I am at home on vacation and there is no food at home. I asked him to give it to the Jia family the day before yesterday.

I haven’t eaten anything.”

Li Changping was shocked after hearing He Yuyu's words, but he didn't expect that He Yuyu had been hungry for two days before he came to his place to find food.

"Then why didn't you come over earlier?" Li Changping said angrily.

"Yesterday I went to the old lady's house. When she saw it was me, she hid the food. I was afraid that Brother Changping would do the same..."

He Yuyu said weakly.

Li Changping frowned when he heard He Yuyu's words, but he didn't comment. He just stood up, touched He Yuyu's head, and then said: "From now on, if there is no food at home, I will come to Brother Changping's house."

Eat, as long as you clean the room for Brother Changping after eating.

How about just treating this meal money as wages?"

After hearing what Li Changping said, He Yuyu was silent for a moment, and then said with red eyes again: "Well, thank you, Brother Changping."

"Okay, don't cry anymore, we are all big girls now.

But your brother can’t do this. In this case, you go to the uncle, tell him about your matter, and ask him whether he cares about it. If he doesn’t care about it, go and tell the street and ask the street to send someone to deal with it.

Send it to your father."

Li Changping looked at the thin He Yuyu and said to He Yuyu.

"Brother Changping, do you really care?

Will the streets really send me to my dad?

Doesn’t my dad no longer want me and my brother?”
