Spring Full Courtyard: Starting from the Researcher

　　As for the rectifier, its function is to convert alternating current into direct current.

　　Having said so much, in fact, this ignition tube has only one use in real life - it was installed in early electric locomotives as part of the rectifier circuit.

　　In short, it means that without this squib, the electric locomotive cannot start.

　　So this ignition tube is actually the core device of the entire electric locomotive.

　　It is a pity that the development of electric locomotives in our country in the [-]s is not optimistic.

　　To be clear, in the [-]s, our country was still imitating the electric locomotives of the Big Brother Soviet Union in the [-]s.

　　Not only that, because the problem of the ignition tube has not been solved, even if it is an imitation electric locomotive, there is no way to put it into use.

　　If He Yushun can solve the problem of the ignition tube, then the country can manufacture an electric locomotive that can be put into use.

　　This achievement is enough to raise He Yushun's engineer level by at least two levels.

　　Just do it.

　　He Yushun majored in electrical engineering when he was an undergraduate before, so he has a deep understanding of electronic devices such as ignition tubes.

　　The knowledge of this rectifier is still in my head.

　　He Yushun immediately started to pick up the pen and draw the drawings.

　　The circuit is something that needs to be drawn and calculated with a pen.

　　Only in this way can we make things and make products.

　　In this way, He Yushun sat in the office all morning with paper and pen.

　　After a morning, the research on the device of the pilot tube is almost complete.

　　If these technologies were placed in the world before He Yushun crossed over, they would simply be a piece of cake.

　　He Yushun will do it now, it must be simple.

　　Of course.

　　Even if it is simple, it is not something that can be done in one morning.

　　However, it is estimated that it will be almost two or three days.

　　When the time comes, I will ask the big leader for instructions, saying that he has new research results, and let him take his technology to the research base of domestic electric locomotive production and use it to see if it can be applied.

　　If you can, then it's definitely no problem to have a fourth-level engineer yourself.

　　In this way, his salary can rise a lot, and his status is also skyrocketing.

　　Of course. ,

　　It's still a bit difficult to get more than a third-level engineer.

　　After all, a third-level engineer or above can be called a chief engineer.

　　This title is not something that ordinary people can carry.

　　However, He Yushun was already satisfied that he could become a fourth-level engineer.

　　The main thing is that he wants to rely on this and let the big leader marry Lin Xiaomu to himself.

　　The big leader is his future father-in-law, so he must show him some achievements, so that he can trust Lin Xiaomu to himself.

　　Speaking of Lin Xiaomu, He Yushun felt a little bit of guilt in his heart.

　　Although he said that he was no longer a first boy, but this is also a matter of his life.

　　This body in this life is really a first-time boy.

　　However, it was the first time that he used it on Qin Jingru.

　　It's not a loss to use it on Qin Jingru, who is also the first time, but she still feels a little guilty about Lin Xiaomu's words.

　　However, He Yushun did not struggle in this regard for too long.

　　As long as his heart is with Lin Xiaomu, he will be fine.

　　This is how the morning passed.

　　He Yushun went to Director Yang to ask for a half-day leave, saying that he had something to deal with in the afternoon.

　　Director Yang approved He Yushun's request for leave without even asking the reason.

　　in the afternoon.

　　He Yushun first went to the cafeteria for lunch.

　　When the people in the cafeteria saw He Yushun, they stopped calling him Director He, and they all changed their names to Deputy Director He.

　　Even He Yuzhu, who was watching the shift in the cafeteria, called He Yushun the factory manager with a smile, and the people next to Le's side were happy.

　　He Yushun rolled his eyes, not wanting to pay attention to his stupid big brother.

　　After eating, he directly rode his Phoenix 18 bicycle and went to the Red Star Mahjong Hall.

　　Arrived at the Red Sea Mahjong House.

　　Zhou Li is waiting here.

　　However, after He Yushun stopped the bicycle, he did not see the forest.

　　"Hey, where is your eldest brother in the forest?"

　　He Yushun asked curiously.

　　"Brother Hong, he had a fight today. At the Drum Tower, he took his brothers there. He left me here and said he wanted me to show you."

　　He Yushun nodded.

　　The Drum Tower is at the junction with Xidan Market.

· · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·?????????????????

　　At this juncture, there will be many problems.

　　Especially those of them who are mixed society, the land can be equivalent to the place to eat, and it will not be enough if it is less.

　　Between each gangster, a lot of blood was shed in order to fight for territory.

　　However, these are all things in the forest, and there is no need to worry about them.

　　The relationship between himself and him is just a transactional relationship. He gives the news and he gives the money and it is over.

　　"Okay, take me there."

　　He Yushun got on the bicycle and let Zhou Li lead the way.

　　......

　　On the road.

　　He Yushun asked Zhou Li to tell himself about the family.

　　Zhou Li eloquently said:

　　Listening to the guy himself said that his ancestor was an official of the Braid Dynasty. Although it was not a high-ranking official, he was at the foot of the emperor after all, and that was considered wealth and glory.

　　But then the braids fell, and their family was gone.

　　It's gone, it's gone, but the family is still quite solid, enough for their family to enjoy themselves for a few lifetimes.

　　Up to now, because now this master is a person who eats, drinks, prostitutes, and gambles in everything, his family is naturally defeated by him.

　　No, because I am addicted to gambling, but I have no money to gamble, so I have to borrow money from someone.

　　After borrowing the money, he intends to gamble and wants to win the money back.

　　But everyone knows that out of ten bets and nine losers, one of them didn't win, but was standing on the rooftop.

　　In the end, all the money was lost, and if it wasn't enough, Lin Zhong would naturally lead his men to discuss it.

......... 0

　　They are mixed society, not good people, if they owe money and don't pay it back, something will happen.

　　Fewer arms and fewer legs would be good.

　　When he came to Lin Zhong with his subordinates and took the guy to that person's house, he still hugged Lin Zhong's leg and begged for mercy, but it was useless. What Lin Zhong wanted was money, not your jins or taels. Tears, it's no use calling you grandpa or grandma when you cry here.

　　In the end, when he said that he would cut off his arm and leg without paying the money, the grandson admitted that he still had some things left by his grandparents in his home, that it might be some precious antiques, and that it was used. to get money.

　　Lin Zhong didn't understand this, so he called He Yushun.

　　He Yushun was thoughtful after listening to Zhou Li's words.

　　If this person is really the descendant of some kind of official, then there must be some good things in the family.

　　However, this Lin Zhong is not a fool. He said before that the money for the information is one [-] yuan, but he did not say how much the money was for buying antiques.

　　This Lin Zhong is to let himself go and see. If there is really any good goods, I am afraid that Lin Zhong will take it by himself.

　　After all, he may not understand antique literature, but there must be someone who understands this huge Beidu.

　　As long as you know it's a treasure, you don't have to worry about not being able to sell it for money.

　　Zhou Li, who was on the side, saw He Yushun's expression and continued: "Mr. He, Brother Hong said, when you get there, you can help him read it. After reading it, if there is really something valuable, Brother Hong said you should go first. Pick two pieces, and if you don't charge money, you'll be a friend."

　　Oh?

　　And this thing?

　　After listening to Zhou Li's words, He Yushun obviously had a new understanding of this forest.

　　This person is actually willing to exchange two antiques for his favor?

　　Not bad.

　　Really good.

　　Although this forest seems to be nothing more than a gangster now, but in the future, it is really uncertain.

　　After all, when I saw him before, I thought he was unusual.

　　If you put it in other positions, maybe you can make even greater achievements.

　　Just sending out valuable antiques to make a friend with a promising future is not the courage of an ordinary gangster.

　　Most of the people, it is estimated that they only want to get these treasures in their hands to exchange money, where would they think about this?
