Siheyuan: No One Can Be Left Behind

Li Dongfang did not let the two of them idle either. He checked the parts on the table one by one, and handed them to them after confirming that they were intact, asking them to clean them. Since most of the parts now were still cast iron, the cleaned parts still did not have a shiny texture, otherwise the picture would be more pleasing to the eye.

After determining the usable parts, Li Dongfang continued to dismantle the other two engines. Following the same process, he found that there were many damaged parts. The parts removed from the three engines were not enough to piece together a complete one, not to mention that the engine cylinders also had some problems.

The damage rate of parts made from current materials is still very high, mainly because they are not wear-resistant and rigid enough. This is difficult to solve at present. Although Li Dongfang has developed carbon steel, it still takes a certain process to use it in parts production. It is currently impossible to find finished parts.

Li Dongfang probably had some repair plans for other things in mind, but he was troubled by the fact that none of the piston shafts were in good condition. These engines were too primitive. They were not rotary piston engines but the old-fashioned straight-forward crank-connecting rod structure, which was not what we often call torque-driven.

After checking the piston shafts again and again, Li Dongfang felt that one of them could be repaired, but it seemed very troublesome. It would be best if he could find a replacement.

So with the idea of ​​giving it a try, Li Dongfang decided to dismantle the engines of several other motorcycles, just in case one of them could be used. If not, he would have to go to the steel mill and make one himself.

Li Dongfang's interest in this motorcycle has also declined. This kind of engine is really too bad. It has many parts and of course the failure rate is high. It is also heavier, has low power, and does not run fast. It can only be said that it is better than nothing.

[Ding, host, are you signing in? 】

The system popped up a reminder at this time, and Li Dongfang responded weakly.

[Ding, sign in successfully, get the rotary piston engine and supporting parts design drawings. ]

Li Dongfang curled his lips for a moment, but became happy again after thinking about it. Although the rotary engine was invented in 57, it is obviously still an advanced technology now. There is definitely no related technology in China. It would be a great achievement if he could develop it by himself. Moreover, this technology is obviously still being optimized and improved, while his is a mature technology.

If I remember correctly, it seems that Japan only obtained this technology from the Germans in 67 for the production of automobile engines. If we had come up with it first, then our country's engine technology in the automobile industry would have suddenly surpassed the world.

Seeing that it was getting late, Li Dongfang dismantled the other engines and pulled them back, then rode his bike back to the courtyard. As for the others, he would have to wait until tomorrow. He originally wanted to have a deeper discussion with Liang Ladi, but after thinking about it, he gave up. After all, there were too many people in the residential area at night, and the children must be at home.

It was already very late when they returned to the courtyard. After all, the journey was quite long and it was dark halfway through, so Li Dongfang slowed down his cycling speed.

When he returned to the courtyard, he saw a lot of people gathered in the central courtyard. Li Dongfang's heart skipped a beat. Could something have happened again? Could it be that something had happened to the women in his room?

"Zhu Zi, this time it is indeed your fault. Why did you hit him so hard? If anything happens to Damao in the future, the Xu family's incense will be cut off. Why don't you apologize to Damao as soon as possible?"

As soon as Yi Zhonghai said this, which was obviously an attempt to smooth things over and help Sha Zhu evade responsibility, Li Dongfang felt relieved. It must be Sha Zhu who beat Xu Damao again, and in a shady way. However, it had nothing to do with him and was nothing. It was just a regular feature of the Siheyuan.

Li Dongfang pushed his bicycle to the eaves, then walked to his door and stood with the three women who were watching the fun.

"Have you eaten?" Qin Huairu asked first.

"Not yet, what happened again?"

While eating melon seeds, You Fengxia said casually, "It's nothing serious. Sha Zhu beat up Xu Damao."

After listening for a while, I finally figured out that Xu Damao was in a bad mood because he heard from his mother that the blind date that had been arranged was cancelled. Adding to Sha Zhu's sarcasm and sarcasm, he started fighting with him. As expected, he was badly beaten by Sha Zhu and was kicked in the crotch.

This was more than the first or second time the two had fought, and people in the hospital hadn't taken it seriously at first. But this time, Xu Damao was lying on the ground holding his crotch with his face blue. Everyone then realized that he might be seriously injured, and they quickly sent someone to send him to the hospital.

Sha Zhu acted as if nothing had happened and didn't care at all. Yi Zhonghai was persuading Sha Zhu to go to the hospital to apologize to Xu Damao, hoping that the matter could be resolved.

"I won't go, uncle. You saw that it was Xu Damao who started it first, and I fought back. It's not my fault wherever I go."

Sha Zhu still didn't realize the seriousness of the matter. If this matter got out of hand, Sha Zhu might have to stay in the police station for a few days.

"Zhu Zi, do you still take a senior official like me seriously? You have to go today whether you want to or not." Yi Zhonghai felt that his prestige in the courtyard had declined greatly recently. Even Zhu Zi, who was usually the most obedient, seemed to be about to rebel, so he said angrily.

Sha Zhu stiffened his neck and turned his head to see Li Dongfang. His eyes suddenly lit up. He walked over and pulled Li Dongfang and said, "Dongfang, please judge for me. Was it right for me to fight back in self-defense?"

Li Dongfang had originally not intended to care about this trivial matter, but someone behind him reached out and tugged at the corner of his clothes. Turning around, he saw He Yushui sticking her little head out from behind Aunt Shu and tugging at the corner of his clothes, with a pleading look on her face.

The little girl looked so pitiful. Her mother died, her father ran away, and her brother was a freak of nature. Li Dongfang felt sympathy for her. If Sha Zhu was really arrested, there would be no one to take care of the little girl. Besides, Sha Zhu had helped him, so he decided to give him a few words of advice.

"Zhu Zi, although you were acting in self-defense, there is a term called excessive self-defense, don't you know? You should go and see a doctor, apologize, and give Xu Damao the medical expenses. Don't make a big deal out of it. It will be bad if it gets reported to the security department of the police station."

Sha Zhu didn't expect Li Dongfang to say this. He looked around at the neighbors who were whispering and Yi Zhonghai who looked like he hated him for not fighting. He was a little nervous and said,

"Is it really that serious?"

Seeing that Li Dongfang and Yi Zhonghai both nodded, Sha Zhu said weakly: "Then...then I'll go and have a look, but...but I have no money."

Li Dongfang saw Yi Zhonghai looking at him from the corner of his eye, and he quickly said, "If you don't have money, go borrow from the uncle. After all, the uncle will not sit idly by when something happens, don't you think?"
