Go back to the prosperous days and become a layman

Chapter 770 769 The East Wind is Coming
Tuesday, May 4th.

Wan Xianghong didn't sleep well last night.

As a freshman, Wan Xianghong is going to the highest scientific and technological unit today to assist Tang Zhitong in conducting project experiments. He feels both excited and nervous.

Although there were some experimental classes in school, they were relatively superficial. It was because of the need for the incubator project that Wan Xianghong asked her senior schoolmate for advice and gained an in-depth understanding of the laboratory preparation process of ferrite, which was only slightly higher than the theoretical stage.

Wan Xianghong cherished this opportunity very much and was afraid of missing it, so he got up early in the morning, had a quick breakfast in the cafeteria, and then waited for Tang Zhitong at the gate.

Tang Zhitong was also busy until late yesterday. He had to record the trial observation results of the cat climbing frame and also briefly record his ideas about the traction rope, intending to add it as a supplement when writing the trial report.

Due to the limitations of existing domestic technology and materials, the traction rope is best made of leather, especially cowhide, which will look beautiful if it has some patterns branded on it.

Cowhide is still very popular abroad. Cowboys and equestrian enthusiasts all like cowhide products. The sales of backpacks, pencil cases and wallets I tinkered with a while ago also illustrate this point.

However, they can only earn hard-earned money by relying on their novel ideas. Due to the cutting process of domestic cowhide, the leather is relatively thick and the feel is not very good.

According to Director Ye, relevant units have already concentrated their personnel to carry out process improvements.

If the improvement is successful, more cowhide products can be made. Soft cowhide shoes, briefcases, belts, etc. can all be tried. It is estimated that by then the domestic cowhide may not be enough, and the raw materials will have to be imported. Tang Zhitong is looking forward to it.

After finishing all these, Tang Zhitong was afraid that he had forgotten, so he took the time to write a letter to Hao Ren about promoting "pen pals".

Since he also had the status of a representative in the department, Tang Zhitong specifically stated in the letter that this was "an immature idea" of his as a junior, and whether to adopt it would be up to Hao Ren to decide.

After sealing the envelope, Tang Zhitong continued to write letters, one to each of Tang Gang, Tang Rong, and Su Nianbin.

In order to dissuade Tang Wenbang and his son from coming to Beijing, Tang Zhitong, in addition to saying that everything was fine here and they didn't need to worry, also half-truthfully introduced the conditions for coming to Beijing.

Due to the "complaint to foreigners" incident a while ago, ticket offices across the country have tightened the issuance of tickets for visiting relatives and friends.

Moreover, while passengers are on the train, conductors will check their tickets over and over again. Even after leaving Sijiucheng Station, people from the Hometown Return Office will conduct large-scale random checks.

The reason why it is half true and half false is that there is no written evidence of this practice...

The reply letters to Tang Rong and Su Nianbin were much simpler. They simply encouraged them to continue studying hard. However, the letter to Tang Rong contained more content, explaining that he had asked someone to inquire about the application matters and asked her to be patient. He would inform her in time when there was any news.

After finishing all these, Tang Zhitong lay on the bed and simulated several times how to create conditions in the Metallurgical Institute to "steal" neodymium before falling into a deep sleep.

Tang Zhitong was also thinking about today's experiment. After breakfast, he rode his bicycle away without waiting for Xiao Wang to go out.

He found a mailbox on the way and posted all the letters from last night. Then he took out the finished mold and rode towards the Iron and Steel Institute.

"Xiang Hong, are you getting impatient?" Tang Zhitong saw Wan Xiang Hong squatting at the gate of the Iron and Steel Institute from a distance. He stopped the car and looked at his watch. It was not yet half past seven.

"No, I just got here too." Wan Xianghong staggered when she stood up. She had been squatting for too long and her legs were numb.

"You just got here? Your legs must be numb from squatting. You can move around first. There's still time." Tang Zhitong wanted to lend a hand, but there was a bicycle between them. Fortunately, Wan Xianghong didn't fall.

After her lie was exposed, Wan Xianghong smiled embarrassedly. She moved her arms and legs a little and felt less uncomfortable, then she sat on the back seat of Tang Zhitong's bicycle.

The Iron and Steel Institute is not far from Zhongguancun North Second Street. When Tang Zhitong drove Wan Xianghong to the Metallurgical Institute, there were not many people working there.

Although it was not yet eight o'clock and there was still half an hour before the agreed time, Zeng Xinghuai was already in the office.

"Are you here? Come on, I'll take you there." Zeng Xinghuai greeted Tang Zhitong kindly.

"Director Zeng, this is Wan Xianghong, a top student from the Iron and Steel Institute. I asked him to come here to supervise and help. You are very busy with work, and I dare not waste your precious time." Tang Zhitong hurriedly stopped this big shot in the technology community. It was enough of a headache for him to have a custodian watching him. If Zeng Xinghuai went over to watch him too, he would not have the chance to steal even if he wanted to.

Wan Xianghong was confused. She was only a freshman, so when did she become a top student?

"Oh? Iron and Steel Institute, not bad, it's a key university in our country." Zeng Xinghuai nodded to Wan Xianghong amiably. He was indeed busy, so he habitually checked his watch and said, "Okay, then you can take Xiao Wan there. I have informed the relevant departments, and they are all at work now."

"Okay, thank you Director Zeng, you go ahead and get busy." Upon hearing this, Tang Zhitong didn't dare to say anything more. He pulled Wan Xianghong, who was in a daze, and walked out of Zeng Xinghuai's office.

"Brother, when did I become a top student?" Wan Xianghong came back to his senses after walking a long way out of the office, and said in a low voice with a red face.

"He is a top student after only spending a few months preparing for the exam. I can't do that if it were me." Tang Zhitong smiled and said perfunctorily, but he sighed in his heart that only today's college students are clear-headed, humble and pragmatic.

It’s hard to say what will happen in the next few decades. With the increasing employment pressure, many college students will package their resumes to perfection under the guidance of AI or various paid artificial “mentors” when they are about to graduate.

Tang Zhitong has actually seen the resume of a certain operator. It is outrageous but relevant, and relevant but absurd: I have had the honor of participating in the discussion, commenting, and liking of various advanced domestic fighter jets and advanced ships!
He spoke as if everyone had done it before. Tang Zhitong had done it himself, but he was proud but didn't show off.

"No, no. In my heart, you're much better than me." The more Tang Zhitong praised her, the more embarrassed Wan Xianghong felt.

"Haha, don't be so modest, we'll follow the steps later. Time is tight, we only have one morning." Seeing that Wan Xianghong was a little at a loss, Tang Zhitong stopped praising her.

In terms of ingredients, Wan Xiang Hong is part of his plan. It would be great if the custodian could keep an eye on Wan Xiang Hong.

Since Zeng Xinghuai had accompanied Tang Zhitong to the storage room last time, and Zeng Xinghuai had given advance notice, Tang Zhitong led Wan Xianghong in without any effort.

The custodian was a young female comrade. The lunch box on her desk was open, with two small steamed buns in it.

"Sorry to have delayed your breakfast." Seeing this, Tang Zhitong came up and said some polite words.

"It's okay, it's all for work." The custodian smiled and said without any dissatisfaction. He closed the lunch box again, found beakers and forms for the two of them, and planned to watch over the preparation of the ingredients before eating breakfast.

Tang Zhitong learned about this the last time he came here. The mixing of ingredients needs to be done under the supervision of the custodian, and the person who mixes the ingredients needs to fill in the ingredients and their respective weights.

Tang Zhitong placed the beaker and table next to the balance on the laboratory table and briefly explained the rules to Wan Xianghong. Wan Xianghong nodded and took out a pen from her bag, intending to record the name and weight of the raw materials.

Tang Zhitong compared his memory from last time and confirmed the locations of neodymium, iron, and boron again. He took a deep breath and prepared to make some moves before mixing the ingredients.

The mainstream components of common magnets at present are iron oxide, barium oxide, and ferrous chloride, while super magnets are made of neodymium, boron, and iron.

Not only are the locations of the raw materials in the storage rooms different, but the colors of the raw materials are also different.

If you don't create trouble to distract the custodian, the package swap won't be completed even if there is a hack.

What Tang Zhitong wanted to do was simple. He would make the custodian cough violently, and then let Wan Xianghong take care of her while he quickly finished the ingredients.

If you want to cough violently, it is not difficult to do so. Just "feed" the custodian a little bit of water.

Those who have life experience know that whether it is choking on water, choking on one's own saliva, or being blocked by a foreign object, the feeling is so intense that you can cough up tears.

As a member of the editorial team of the Manual, Tang Zhitong, although he had never studied medicine, knew where to put the water in the custodian's body.

The cheat cannot pretend to be a living person, but it can send foreign objects into the body of a living person.

The next step was when the "skills" were truly tested. Tang Zhitong silently said "sorry" to the custodian in his heart, and then poured a small sip of 37-degree warm water into the pot.

The custodian coughed lightly at first, then bent over and covered his chest with his hands and began to cough violently.

"What's wrong? What's wrong? Xiang Hong, come over and give him a pat on the back." Tang Zhitong remained calm. While pumping out the water that had just been sent in, he sent Wan Xiang Hong away, intending to quickly get the desired raw materials from the shelf.

Unexpectedly, before Wan Xianghong reached the custodian, the young female comrade's body went limp and she slowly slid down.

Tang Zhitong was shocked and thought that his operational error had caused a loss of life. He no longer cared about the ingredients at this time and hurried forward to see what was going on.

“Sugar… sugar…” The custodian collapsed to the ground, muttered two words softly, and then fell silent.

Tang Zhitong heard it clearly and breathed a sigh of relief. He immediately grabbed a piece of candy from the space and stuffed it into the custodian's mouth. At the same time, he said to Wan Xianghong, "Xianghong, come over and help her. Don't let her choke."

"Brother, is this... okay? Do you want to call for help?" Wan Xianghong was very obedient. He supported the custodian and asked with a worried look on his face.

"Oh, it's no use calling for help. She has hypoglycemia. Eat a piece of candy and she'll be fine in three to five minutes." Tang Zhitong sighed. From the two words "sugar" that the custodian said before she fainted, it can be seen that she knew she had this problem. It might be that she didn't have time to eat breakfast today, and the sip of warm water induced hypoglycemia.

Wan Xianghong saw that Tang Zhitong was confident, so she didn't say anything.

Tang Zhitong had suffered from hypoglycemia when he was working as a cow or horse before. He really passed out. His friend was so scared that he was incoherent and carried him to the nearest clinic.

The doctor had experience and asked the patient to go out and buy two pieces of candy. With the candy, the patient recovered after a while. If there was no one around, it would be hard to say what the consequences would be.

Later, Tang Zhitong also looked up relevant information himself. The fastest way to relieve hypoglycemia is to drink or inject glucose, but who usually carries that thing with them?
Some people now say that they have seen disaster victims fall down while walking and never get up again. In fact, it is because of hypoglycemia caused by insufficient energy intake. If someone can put a piece of sugar in the mouth of the disaster victims, or even a mouthful of rice soup, they will recover.

Taking advantage of this period of time, Tang Zhitong openly prepared the raw materials for NdFeB magnets: 35% neodymium, 64% iron, and 1% boron.

The scale in the storage room is very accurate, the kind with small weights.

Tang Zhitong didn't prepare much, just 200 grams, which was used for one set of incubator and one set of hair dryer for Xiao Wang. The rest could be given to the Metallurgical Institute for research. He couldn't let the custodian faint in vain.

Although the ingredients were prepared according to neodymium iron boron, Tang Zhitong filled in iron oxide, barium oxide, and ferrous chloride on the record sheet, and wrote them in Chinese characters.

The reason for writing Chinese characters is that all the raw materials in the storage room are written in chemical formulas. In case of investigation later, Tang Zhitong plans to use the excuse that he is not good at chemistry, he is nervous, he read it wrong, or he took the wrong thing.

As long as I can drag it out for a whole morning and the supermagnetic processing is successful, I believe no one will hold on to this point. After all, by then, no matter how hard you try, you will say that you have made a major invention "accidentally"!
After putting the bottles and jars of raw materials back to their original places, Tang Zhitong stirred the raw materials vigorously with a glass rod.

Maybe because the metallurgical institute wanted to make mixing of ingredients easier, many of the raw materials here were in powder form, which was just right for Tang Zhitong to stir to hide them from others.

After Tang Zhitong finished his work, the custodian slowly woke up. When Wan Xianghong found out, she excitedly told Tang Zhi, "Brother! Brother! He's awake, awake!"

The custodian also heard the noise, and the first thing he said when he opened his eyes was, "Didn't I scare you guys?"

"I was so scared. I thought... If my brother hadn't fed you some candy and said you would wake up soon, I would have gone out to call for help." It was the first time that Wan Xianghong saw someone faint in front of her, and she couldn't help but feel excited.

"It's an old problem. I got up late this morning and didn't eat, so I got it back unexpectedly. Sorry for bothering you, thank you." The custodian's spirits had improved visibly, and he even wanted to stand up after he finished speaking.

"I'm glad you're okay. It was all because we came here to borrow the laboratory. We should be the ones to say thank you." Although he thought nothing serious would happen, Tang Zhitong still breathed a sigh of relief when he saw the custodian stand up.

"Sit down for a while and drink some water." Wan Xianghong helped the custodian sit on a chair, then picked up the thermos and poured her a glass of water.

"Can you do it yourself?" Tang Zhitong was afraid that he would be discovered using rare earths, and he wanted to leave immediately.

The last time I came here, Zeng Xinghuai had already said that most of the rare earths in the storage room are imported and the prices are very high.

In the eyes of these scientific and technological personnel, these are all non-renewable resources, and they are used by the gram in experiments. They will definitely not use more than half of them like Tang Zhiren did, and no one will use this stuff to make computer cases.

"I'm fine. Have you finished matching?" the custodian asked with an embarrassed smile.

"Well, time was tight, and we only had the morning scheduled, so we didn't wait for you to wake up. Do you need a check-up?" Tang Zhitong handed over the registration form and pointed to the beaker on the table.

"No, thank you for just now." The custodian took a look at the forms and saw that they were not valuable, so he gave up the idea of ​​checking them for the time being.
