Siheyuan: The opening earthquake of stealing and replacing pillars

People tend to become lazy on rainy days. After eating two buns, Zhu Lin lay down on the bed again, looking out the window, not knowing what she was thinking.

As for He Yuzhu, he was in high spirits at the moment. As a man, he knew everything. Besides, the principle of the brushless motor itself was not complicated. What was complicated was the control circuit. The biggest challenge was how to achieve smooth operation!

However, there is a system to assist, so this problem can be easily solved!

But after doing all this, he suddenly found that his wisdom had exploded, and one brilliant idea after another flashed in his mind, such as making an adjustable power supply circuit, using a 220V to 24V transformer to connect a set of rectifier bridges and filter capacitors to convert AC power into stable DC power, and then using four filter capacitors plus an inductor and two potentiometers soldered on the circuit board, and then building a bridge, a simple adjustable power supply is ready.

Then connect the brushless motor to achieve perfect voltage control. The number of revolutions changes with the voltage. Hey, doesn’t this mean that we can build an electric bicycle?

"Haha, I'm such a genius!"

"..." Zhu Lin laughed silently.

"Wife, when we get back to Kyoto, I'll make you an electric bicycle so you don't have to pedal to go to work anymore!"

"Electric bicycle? What kind of vehicle is that?"

"Of course it's an electric car!" He Yuzhu jumped onto the bed excitedly, and proudly said: "With the advent of new energy, transportation will be revolutionized in the future!"

Zhu Lin stared at He Yuzhu's face and said admiringly: "Yuzhu, you are amazing!"

"Hey, you just knew it!"

"Haha, don't—"

……

At noon, He Yuzhu bought a net bag of hairy crabs and went to Professor Lin's house for dinner. After dinner, Professor Lin asked Zhu Lin to stay and pass on his teachings. He Yuzhu was bored, so he rode the old lady's bicycle out for a stroll. Hangzhou city was not big, so he only went to Chinese medicine shops. There was no other way, the materials for making "Shen Zao Wan" could not be purchased in the mall, otherwise it would be considered cheating and the system would confiscate it.

After going around in circles, He Yuzhu arrived at the Provincial Library. In front of him was the Shahe River. There was no way to go any further, so he planned to go back. But when he turned around, he happened to see some shadowy figures in a park. He Yuzhu was very familiar with this scene. It turned out to be the black market!

The black market in the south is different from that in the north. People here conduct transactions almost openly and are not afraid of being seen by others. He Yuzhu was very surprised. Is it so awesome?

With doubts, He Yuzhu pushed the cart into the park. The park was not big and the end could be seen at a glance. There was a corridor with small vendors preparing to ship goods on both sides. There were buyers, but very few. It was probably because it had just rained!

"Do you want a ticket?" After I had taken two steps, someone came up to me and asked.

“Are there national food coupons?”

When the man heard He Yuzhu's accent, he immediately became alert: "You are not a local?"

He Yuzhu shook his head: "I came to Hangzhou on a business trip, and the tickets are all used up. I'm worried about this!"

The man looked at He Yuzhu and felt relieved when he saw that he did not look like a plainclothes officer.

"I have national food coupons, 40 cents per pound, do you want to buy or exchange?"

He Yuzhu often visited the black market, so he knew the twists and turns involved. Without further ado, he took out a big black ten and bought 20 kilograms of national food coupons.

After the transaction was completed, he walked inside and saw people exchanging goods for eggs, rice, and of course, other side dishes as well.

"Damn it, I'm itching to watch this!"

He Yuzhu was thinking about whether he should sell something. Previously, he had been focused on making televisions, but this thing could not be made in a day or two. It would be better for him to get some radios from the mall and sell them to cash in and save more money to prepare for the post-reform and opening up period.

In fact, he already has 50,000 or 60,000 yuan in capital, because he can get money by signing in, and the rewards are getting more and more with the host's achievements. As long as he persists, he will become a millionaire in the near future. However, signing in every day is also quite troublesome. Many times He Yuzhu was too lazy to punch in, otherwise he would have more savings now.

After finding a vacant space, He Yuzhu parked his bicycle, put the Longjing tea he bought for his father-in-law on the back seat into the space, and then quietly replaced it with a Shanghai brand tube radio, which he bought in the mall for less than 30 yuan.

As the radio was turned on, a childish voice immediately rang out: "Tick-tick, tick-tick, kids, the little speaker has started broadcasting!"

Well, when the news came out, people were shocked and gathered around to watch. Although it was already 78, radios were still hard currency. Just like this Shanghai brand tube radio, the official guide price was yuan, and it had to be purchased with a special ticket. Don't underestimate this ticket, it's really not easy for ordinary people to get one.

According to last year's statistics, the national average annual income of workers was 270 yuan. Note that this is only the workers' income, which is only about 22 yuan a month. One has to go without food and drink for half a year to be able to afford a Shanghai brand tube radio. Not to mention that you need a ticket. Ordinary people simply can't afford it. This is the first time it appears on the black market. No wonder everyone is shocked.

The appearance of this radio is very delicate. As it is a large unit, it looks very impressive at home. The body of the radio is made of the same wear-resistant decorative fireproof board as the sewing machine, and the beautiful wood grain makes it look very noble.

So when the voice from the radio came out, people gathered around He Yuzhu.

Someone asked tremblingly, "Comrade, are you going to sell this radio?"

He Yuzhu took in everyone's expressions and said with a smile, "If you take it out, you must be selling it!"

"how much is it?"

Everyone pricked up their ears when they heard this.

"The department store charges 125 yuan for a ticket, but mine costs 130 yuan without a ticket. Isn't that a good deal?"

"No problem?"

"Absolutely no problem, uncle. If you want to buy it, you can try it on the spot and pay if you are satisfied!"

Although the department store was ten yuan cheaper, you still had to buy a ticket. I don't know how many people were stumped by this ticket. People who could come to the black market to hang out had some money. When they heard that they could take the goods away on the spot, someone immediately rushed out and shouted,

"One hundred and three, I want it!"

This man was none other than the peddler who sold the national food coupons to He Yuzhu. Perhaps he saw a business opportunity or something else, and he seemed impatient when paying. When he paid, the audience became anxious, and they all regretted that they were a step slow. Some of them even asked unwillingly if there was any stock.

"Don't worry, I still have three at home, wait for me to go back and get the goods!"

"Go quickly and come back soon, we are waiting for you here!"

Look, how much the people need it!

What are you waiting for?

He Yuzhu rode his bicycle out of the park. In order to prevent anyone from following him, he deliberately went around several streets. It is better to be safe than sorry. Finally, he turned into a large courtyard and used the excuse of going to the toilet. When he came out again, there were three more cardboard boxes on the back seat of the bicycle...

He Yuzhu was in a good mood as he made a net profit of 520 yuan just by going out. This was more fulfilling than signing in and was also very interesting.

When they returned to Professor Lin's house, the two had already prepared the meal. Zhu Lin was the chef. Although her cooking skills were not as good as He Yuzhu's, it was easy for her to cook a home-cooked meal...

……

In the next few days, the couple wandered around Zhonghai and stayed in Suzhou for two days. They took a lot of photos and short videos. They both had a great time, especially Zhu Lin, who simply let herself go. So when it was time for her to go to work, she was reluctant in every way and couldn't concentrate.

After his wife went to work, He Yuzhu did research in the hotel to further improve the application of brushless motors. During this time, the factory director called and said that the school was preparing to hold an opening ceremony and asked him to go back as soon as possible. Because the part-time team he organized during the summer vacation won unanimous recognition from the school leaders, he was specially approved to join the school Youth League Committee and planned to arrange for him to give a speech at the opening ceremony on behalf of the 77th freshman.

This is nonsense! I am doing this for my own benefit, not for the public good!

He Yuzhu felt guilty, so he rejected the school leaders' kindness on the grounds that the research on brushless motors had reached a critical moment. He was mainly afraid of too much trouble.

Director Hou couldn't do anything about him, and finally threatened him that if he couldn't produce research results by then, he would be sent to the frontier to feed sheep.

He Yuzhu said, haha, by that time, let alone being exiled, you might even ask me to curry your favor!

Time flies. At the end of September, Zhu Lin's internship was finally coming to an end. She had also completed her graduation thesis under the guidance of Professor Lin. On the day of graduation, the school held a farewell party for her. During the three months of getting along with each other, everyone had established a deep friendship. For example, Li Zhuyun and Zhu Lin are now like sisters. Their relationship is so close that they were reluctant to part and cried their hearts out. Even He Yuzhu was deeply moved by their friendship.

After packing their luggage, the couple prepared to return to Beijing tomorrow!

But that very night, the young wife suddenly fell ill. No, she was very weak and listless. However, both of them understood medical knowledge and could tell at a glance whether she was sick or not. But Zhu Lin just felt weak all over and nauseous at the same time. She felt like vomiting if she ate something oily at night!

As she was talking, she ran to the bathroom and laid over the sink, trying to vomit but unable to.

"Where do you feel uncomfortable?" He Yuzhu patted Zhu Lin's back gently and asked with concern.

"I can't really explain it, I just feel a little nauseous. Maybe I'm too tired these days!" Zhu Lin paused for a moment, her face slightly flushed.

When He Yuzhu saw her like this, he became even more worried. However, an idea suddenly occurred to him, and the TV scenes he had seen emerged in his mind. The next second, he began to rejoice.

"Wife, you are not pregnant, are you?"

"No way?" Thinking of the symptoms of pregnancy, Zhu Lin was a little bit unbelieving.

"What do you mean by no way? She must be pregnant. That's how it's played in TV dramas. Haha, I'm going to be a father!" He Yuzhu excitedly picked up Zhu Lin and started spinning around.

"I'm going to be a father, I'm going to be a father, haha!"

"Stop turning, I feel dizzy!"

"Ouch, sorry, I'm too excited!" He Yuzhu put his head on Zhu Lin's belly, listened carefully, and suddenly exclaimed: "Wife, I can feel our child's heartbeat!"

"Go~"

Zhu Lin was embarrassed and said, "It's only been a little while, and it's not even complete yet!"

Although she said this, she felt that there seemed to be some movement in her stomach. She couldn't help but want to touch it with her hands, and a maternal smile appeared on her face...

"Hehe~"

That night, both the couple couldn't sleep.

To be on the safe side, He Yuzhu took Zhu Lin to the hospital for a check-up early the next morning and completely forgot about returning to Beijing. What could be more important than a child?

The test results came out soon. Zhu Lin was already more than two months pregnant. Due to her good physical condition, apart from occasional morning sickness, she thought it was just a problem with the food, so she didn't take it seriously.

As for menstruation, hey, these days, most people don’t think about pregnancy.

After coming out of the hospital, Zhu Lin became He Yuzhu's key protection target. He was very careful not to get hurt, but his excitement was beyond words.

"Oh, please stop doing weird things. It's so embarrassing if people see us!" Zhu Lin really couldn't stand He Yuzhu's caring look, as if he was coaxing a child.

"Whoever wants to watch can watch, I don't care about them, I only care about my big baby and my little baby, hey, what do you think will be my mom's expression when I tell her later?"

what expression?

Of course she was happy. Zhu Lin imagined how her parents looked when they answered the phone, and her heart was filled with sweetness.

When the couple returned to the hotel, He Yuzhu couldn't wait to call Kyoto.

"Mom, Linlin is pregnant!"

"Wow!" Mother Zhu's head was buzzing, and she asked in a trembling voice: "Yuzhu, tell me again, who is pregnant?"

She couldn't believe it. The couple had been married for almost a year and there was still no news. How could a mother not be anxious? It was a common problem for old people. They all wanted to have grandchildren.

But the results of their examinations showed that there was no problem at all, but they just couldn't get pregnant. Isn't that strange? So when she heard that her daughter was pregnant, she was so excited that she wanted to cry.

"Mom, your daughter is pregnant!" He Yuzhu said happily to Mother Zhu.

On the other end of the phone, Zhu's mother's voice was a little choked up: "Okay, okay, I'm glad you're pregnant. Now I'm relieved!"

"Mom, don't cry. This is a good thing. You should be happy!" He Yuzhu comforted.

"Mom knows, I am just happy, woo~"

He Yuzhu felt that his mother-in-law was a little bit unable to stop the car, so he quickly handed the phone to Zhu Lin: "You comfort the old lady!"

Zhu Lin rolled her eyes at him: "It's all your fault, why are you making so much noise!"

"Mom~"

"Linlin~"

The mother and daughter talked on the phone for a long time. He Yuzhu wanted to interject occasionally, but was ruthlessly pushed away by Zhu Lin, who said that men should not pry into women's conversations.

Well, let’s prepare some milk powder. There is no milk on the train, so we must get enough nutrition. After all, we have two mouths to feed, hehe!

Thinking of this, He Yuzhu rushed into the supply and marketing cooperative next door.

After resting in the hotel for another day, the couple set out on their journey home. This time they did not reverse the car because the bus was too bumpy and the pregnant woman could not stand it, so they bought train tickets directly in Hangzhou and then changed trains at Zhonghai Station. Fortunately, He Yuzhu bought a sleeper berth and they returned to Kyoto safely.
