Development of productivity started in 1981

Chapter 81: Inventory before school starts
At Yangzhou Wharf, Wang Jiankun arrived a few minutes before the C202 driven by Wang Zhaowei departed.

"Jiankun, you're finally here, come up quickly, I'll have them tie up the speedboat."

"Okay, Zhaowei, thank you for your help. I'll throw the rope on your boat and ask them to secure it at the stern."

Soon two trainee crew members came to the stern, took the rope that Wang Jiankun threw over and tied it up. Wang Jiankun went down to the dock and then went to the cockpit from the gangway on the side.

It was exactly 6 o'clock in the evening, and Wang Zhaowei asked the trainee captain who was following him to drive the boat away from the dock.

Wang Jiankun waited for a while without disturbing them, because leaving the dock was a rather troublesome operation and the rudder and speed of the ship had to be controlled well, otherwise the transport ship might be damaged and the passengers might fall and get injured due to the collision.

After C202 successfully left the dock and headed south along the Beijing-Hangzhou Grand Canal, Wang Zhaowei came over to say hello to Wang Jiankun.

"Jiankun, have you eaten? If not, I'll take you to the kitchenette to make something to eat."

"Okay, it won't be too much trouble, right? Do you have any food prepared on the boat? I didn't see them cooking on Wang Yongjin's C201. They all went to the canteen at the dock to eat."

"It's not a big deal. There are three of us who haven't eaten yet. I'll cook now that I have time. I'll just make noodles with a few fried eggs. I brought some moldy tofu and sour peppers from home."

"That's fine. The Shanghainese cuisine I had for lunch was sweet and some of it was half-cooked. I can't get used to it. It's not as good as Huaiyang cuisine. By the way, why didn't you three eat? There are mobile vendors selling food at the pier, and there are also small restaurants selling food."

"There are three of us. One of us and I can't get used to the food here because it's too light. The other one wanted to save some money, so he cooked with us on the boat. He brought a lot of sour peppers and fermented tofu as dishes."

"Oh, I see. Then we still need to buy some meat and vegetables. We will be sailing on the Yangtze River for a long time, so we need to keep up with the nutrition. Otherwise, we might get sick and faint. That would be terrible."

"Well, tonight I wanted to go fishing because I didn't buy meat in advance, but the fish wouldn't bite in the winter, so I just had a simple meal. I usually buy some fish, meat, and vegetables. I still have some Chinese cabbage, so I'll put some in the noodles later."

Wang Zhaowei and I went down to the small kitchen behind the deck of the ship. Seeing that the seasoning jars were neatly arranged and cleaned, I nodded with satisfaction.

Wang Zhaowei picked up the pot, scooped some clean water from the iron bucket next to it to rinse it, then put the pot on the gas stove, added most of the water to the pot, lit the gas stove and covered it with a lid.

While waiting for the water to boil, I picked up a small frying pan and fried eggs on another stove. I fried 5 eggs in total. Then I washed and cut the cabbage and stir-fried the cabbage with the remaining oil from frying the eggs. The cabbage was very sweet after being cut into pieces, and tasted better than cooking it directly in water.

The water took a long time to boil. Wang Zhaowei judged that it was boiling by listening to the sound, so he lifted the lid of the pot and put the noodles in. When putting the noodles in, he asked Wang Jiankun about his appetite and finally put in 2 kilograms of noodles.

While cooking noodles, Wang Zhaowei reported to Wang Jiankun on the recent shipping situation, which was similar to what Wang Yongjin had reported. He also proposed stopping at several other small cities. However, Wang Jiankun saw that the occupancy rate was still good, the berths were basically full, 7% of the seats were occupied, and the cargo hold was also full, so he suppressed the idea of ​​stopping at small cities.

Let them train more people and build good relationships with the docks. When there are more ships in the future, there will be competition with other transport ships. Only by building good relationships now can they gain a firm foothold in the future.

The noodles were soon half cooked. Wang Zhaowei put the cabbage in and stirred it. When the cabbage became soft, he turned off the heat.

He first took a lunch box for Wang Jiankun, put two fried eggs in it, and then scooped most of the box of noodles for Wang Jiankun.

He also scooped up most of the noodles, and then picked up some sour peppers and fermented tofu. Wang Jiankun tasted it and felt it was a little bland, so he also picked up some sour peppers and fermented tofu.

Not to mention the simple cabbage noodles with fermented tofu and sour peppers, the taste is also very good. I even ordered another half box after finishing it.

After eating, Wang Zhaowei sent Wang Jiankun to the captain's lounge to rest, while he went to replace someone else to eat noodles.

Wang Jiankun lay down to rest and did not get up. He slept soundly and arrived at Hukou Pier at around 7 o'clock the next morning.

After asking the crew to untie the rope, Wang Jiankun boarded the speedboat and said goodbye to Wang Zhaowei and others.

They drove at full speed and arrived at the temporary wharf in Wuyuan County in more than three hours. There they took a motorcycle and a two-wheeled trailer, put the lead cans filled with uranium into the truck bed, and put some local specialties bought in Shanghai into the box on the back of the motorcycle. Then they rode the motorcycle back to the underground base.

I put the uranium on the fourth floor of the underground base, looked at the time and it was already 11 o'clock, so I quickly rode my motorcycle to the scrap recycling station.

When I got there, I saw Zheng Qian washing rice to prepare for steaming. When she saw Wang Jiankun coming, she quickly scooped up some more rice to wash together, because he must have not eaten at this time.

"Jiankun, we were all guessing when you would be back. Yu Zirun and I guessed correctly, but they all guessed wrong and said you would report directly to school tomorrow."

"You said you'd be back today, so it must be today. What are you planning to eat for lunch?"

Stew the rice, stir-fry two vegetables, shredded potatoes and lettuce, and make a big dish of stewed pork ribs with dried beans, and then make a sweet potato vermicelli soup.

"Well, that sounds okay. Is the portion enough for me?"

"It's enough to eat. We originally made some extra stewed pork ribs with beans, planning to eat what we couldn't finish in the evening. Now that you're here, we'll make one more dish in the evening."

"That's good. Why didn't the men come to help and let you two cook?"

"The food they cook is not tasty either. They have been asked to do the physical work, such as chopping bones, cutting vegetables, washing pots, etc. They are also responsible for washing dishes. The two of us are responsible for cooking and watching the fire."

"Oh, this division of labor makes sense. I thought they bullied you two into doing it all."

"That won't happen. After you leave, we will discuss how to divide the work and cooperate when we have dinner together in the future. Just like doing research now, it will be more efficient if we divide the work and cooperate."

"Speaking of research, have they come up with any results for you to write papers and patent documents after I left?"

"Yes, Yu Min successfully reproduced the green light LED and changed several reaction parameters to obtain a product with higher luminous brightness. He has sorted out the experimental records. Yu Zirun and I are writing papers and patent documents."

"Also, Fang Guihua and his team have made several game console shells. After they were installed, they imported the first and second levels of the box-pushing game. These two days, they are testing the game console's ease of use and the feel for long-term use." Yu Zirun said.

"Oh? So the Push Box game has already successfully developed two levels? Have you played it? Is it fun?"

"There are only two levels, and they look too easy. We looked at them and played them twice and succeeded. If they were always like this, it would be unattractive."

"It won't be that easy. There will be about 30 levels in total, and they will get harder and harder. You guys stay here and cook. I'll go check on them."

After saying that, he went to the computer room first. At this time, Lang Junjian was thinking intently. On the computer was the interface and code of the third level. After thinking for a while, he began to debug to make the picture move as required. When it ran to a certain step, the picture moved incorrectly and did not follow the set direction. It seemed that he encountered a BUG and needed to modify it while testing.

"Lang Junjian, the function call here is wrong. Try changing the function and it should work."

"Huh? Jiankun, when did you come back? I was stuck on this bug for a long time and couldn't find the problem. Look how you can fix it now? It's amazing!"

"Why don't you try changing it first? I just looked at your part and it seems that the two functions are too similar and you misread them, so you didn't find the reason."

Lang Junjian modified the function according to what Wang Jiankun pointed out, debugged it again, and the error disappeared.

"Jiankun, you are amazing. You found the mistake after just a while. How do you usually learn?"

"This is a talent. It's not that I don't teach it, but there's no way to teach it. However, when you make a function library, don't name functions with similar functions too similarly. Otherwise, it's easy to make mistakes when you call them, and it's not easy to check them when you check them."

"Okay, I'll go and modify the function library later."

"Don't be in a hurry. Write the code comments first before you modify it. Otherwise, after you modify the function, you still have to modify the following code. If you don't comment it clearly, can you remember what function you used?" "That's right! It seems that comments are really necessary after writing a program. I didn't write many of them before to save trouble. The bug just now was partly because I didn't write comments, so I couldn't find it for a long time."

"It's good that you understand this. In the future, whether you write programs yourself or teach others to write them, you must remember to write comments."

"Okay, I understand. Go take a look at their results. I'll organize what I wrote earlier."

After leaving the computer room, Wang Jiankun went to the mechanical processing laboratory where Fa Guihua and three other people were working.

The three of them were wearing headphones and watching a small CNC machine processing a wooden part.

Seeing Wang Jiankun coming in, he took off his headphones and said loudly, "Jiankun, we thought you wouldn't come today. We made a few samples. I'll show them to you."

As he said that, he took out three handheld game consoles from the shelf next to him.

The three finished samples all have plastic shells made with a small injection molding machine after the mold is made. The only difference is that the color is quite single, all black. After testing the feel, durability and other items, we will consider making a batch with plastic particles of different colors. Then Wang Jiankun will send them to Guangzhou for Xingyao Electronics to trial sell through distribution channels and customize the appearance based on the feedback.

Wang Jiankun took the machines and tried them out for a while. He felt that all three machines were good, except for one whose buttons he was not used to and which made the operation cumbersome.

"Guihua, the buttons on this machine are not very easy to use. They feel a bit awkward to press. It will be very uncomfortable to use them for a long time. What do you think?"

"Yes, they also mentioned this problem when they were using it. This was the first sample manufactured. They discovered this problem after it was manufactured and tested, so they changed the buttons for the next two machines. They think this one with a cross-shaped button is the best to use. It brings together the up, down, left, and right buttons. Pressing the button diagonally can drive the four diagonal directions, and pressing it in the middle is another operation. This greatly reduces the number of buttons. If we play other action games in the future, the advantages of this button will be even more obvious."

"Well, now that you mention it, we should apply for the patent for this button right away. Game consoles will definitely sell well in the future. Not only handheld game consoles, but also large game consoles should be able to use this button."

"I've asked Zheng Qian and Yu Zirun to write the patent documents. They should be ready in a couple of days! I'll ask you about it while we eat."

"By the way, when you guys are making the shell and other devices, are there any difficulties that you need me to solve? Or are there any functional equipment that needs to be added to facilitate you to make small batches of samples?"

"I have an idea, that is, whether we can modify the injection molding machine, that is, to pile up the extruded plastic little by little to make the desired shape, instead of making the mold first and then using the mold to determine the shape as we do now. Making molds is troublesome now. Although CNC machine tools are used, it takes a lot of time to make a set of molds. After they are made, the size needs to be modified because the shrinkage of plastic is different in different situations." Cheng Ming said on the side.

"Yes, Jiankun, we think it's troublesome to make plastic molds, so we plan to make shapes with wood for testing first, and then prepare to make plastic molds. If we can have a way to pile up the plastic little by little to make the desired shape, then making samples should be much simpler." Hu Chunming also said.

Wang Jiankun thought about it and told Chieko about the idea in his mind, asking him to look for information to see if there was any research in this area. To be sure, there was a paper on 3D additive printing published in a journal.

The general meaning is to use a computer to control the movement of the discharging head in three-dimensional space, extrude plastic or other materials that can solidify quickly and control the amount of discharging, so as to create objects of different shapes in three-dimensional space.

The paper also shows the manufacture of cubes, rectangular blocks and human figures made of plastic.

Because the computer performance is not enough and the nozzle and plastic material that control the discharge are also rough, the samples produced are not very smooth and the joints between the front and back are very obvious. However, the author of the paper also looked into the future, saying that if the computer performance is powerful enough and the nozzle and the corresponding materials can control the discharge volume at the nanoscale, then it will be possible to directly print out any structure and machine that humans can imagine.

After reading the paper, Wang Jiankun wondered how this was so similar to his own superpower. Except for the inability to extract elements, the assembly process was almost the same as directly shaping according to the blueprint. The only difference was that the superpower could control the atomic level and used unknown energy, while this type of 3D printing used the property of a certain material to solidify quickly in a certain medium.

Since someone has already figured it out and the principle is not complicated, the difficulty lies in computer performance and 3D modeling, as well as finding materials and nozzles with smaller particle size, suitable solidification time.

So he told Fang Guihua and the other two, "The functional equipment you proposed is very good. You just need to have an idea and not be afraid of not being able to realize it. I have good news for you. Someone has already developed this equipment and published a paper. I will find the information and make it for you to use in a while. During this period, remember to record any ideas you have and tell me. It may be a meaningful new discovery or invention, and you can also publish a paper and patent and get the bonus."

"Okay, I was thinking about how to solve the problem when I was making the mold, and the solution I came up with was actually published in a paper. It seems that our idea is still very meaningful. In the future, we will think more and record more during the experiment."

"I'm going to go out first, you guys pack up and come out to eat."

"Okay, you go first, we'll be there soon."

When I came out, I saw that the dishes had already been served. Zheng Qian was making sweet potato vermicelli soup, Yu Zirun was calling Yu Min to come out for dinner, and Lang Junjian was already helping to move the stools out.

People came to the table one after another. Wang Jiankun took out the specialties he brought from Shanghai and distributed some to everyone. Finally, he took out two large bottles of black liquid and poured half a cup into each person's cup.

"This is a drink called Coca-Cola, which originated in the United States. In 1978, this company cooperated with COFCO to build a bottling plant in BJ to produce this drink. I bought a few bottles in Shanghai this time. You can all try it."

Everyone raised their glasses. Some took a big sip impatiently and then wanted to vomit but were too embarrassed. Some took small sips and felt the bubbles hitting their mouths and tongues.

"This is a carbonated drink with a lot of carbon dioxide in it, so it tastes very special. If you are used to it, come over and pour more for yourself. If you are not used to it, just eat."

Among the seven people, only Yu Zirun, Lang Junjian and Hu Chunming drank it in small sips and then asked for another glass. The others drank it reluctantly and then stopped. They all said they felt like they were taking medicine.

"You're not lucky enough to have this. Do you know how much this big bottle costs? It's 5 yuan, which is more expensive than ordinary wine. You can try it after dinner. Drink it in small sips first, and you will get used to it slowly. This stuff sells very well in Shanghai."

"Okay, let's have some after dinner. Why is it so expensive? It's simple enough looking at the ingredient list."

"It is said that the formula of the raw juice here is a secret one. They don't even apply for a patent for fear that others will know and copy it. The raw juice is shipped all the way from the United States. Everyone knows that imported products are not cheap."

"That's true. I don't know why our money is not as valuable as foreigners' money?" Yu Min asked.

"It has only been a few years since our country entered industrialization, while those European and American countries have been industrialized for more than 1 years. Their production efficiency and annual production output value are high, so according to the exchange rate, our country's money is worthless. They are now thinking about de-industrialization and not earning this hard-earned money, but making money directly through financial means."

"Jiankun, seriously, there are still countries that need to industrialize, so why are we so anxious to develop industry? Can't we just develop the financial industry as you mentioned?"

"When I say deindustrialization, I mean abandoning low-end industries such as labor-intensive industries, and industries with low added value such as the garment industry. High-end industries are still developing, such as the CNC machine tools you three are using."

"Our country was originally built on ruins, and its development stagnated for a period of time. Now of course we will develop whatever industrial projects we can introduce. The financial industry requires a strong economic foundation. It is a game played by wealthy countries. Zheng Qian and Yu Zirun, you two can pay attention to the broadcasts and news in this regard. Their stock market is getting bigger and bigger now, and this is a kind of financial industry."

"Okay, I heard some of them when I was listening before, but I skipped them because they were boring. However, it seems that there are a lot of proper nouns. I looked them up in the dictionary, but many of them are not there." Yu Zirun said.

"I will ask my friends to send some books about economics and the stock market over there. You can take a look at them and write down your thoughts after reading them. Then you can also talk about them to the science students."

"Okay, maybe I should study economics in the future. I think we will need this kind of professionals in the future."

"There's no rush. You can read some books on the subject first and see if you're interested. You also need to discuss it with your family and get their support."

"Okay, I'll study first. There's still time before the college entrance exam."

As they ate and talked, Wang Jiankun told them about his experiences on this trip. They were all very envious and wanted to go out and see the world. Wang Jiankun suggested taking some time off this summer vacation to take them to BJ and asked them to study hard and work on their projects this semester. Wang Jiankun would pay for the travel and accommodation expenses, and they would have to buy the rest by themselves.

Everyone was very excited and eager to go to the capital. BJ was often mentioned in elementary school textbooks and there were often introductions to BJ in the textbooks. They secretly made up their minds to study hard and do well the tasks assigned by Wang Jiankun.

After the meal, several boys cleaned up and washed the dishes according to the division of labor. For those who didn't drink much Coca-Cola just now, they went to pour some more to try. After drinking it again, they got used to it a lot, but they didn't like it particularly. Wang Jiankun didn't force them and drank the rest with a few people who were used to it.

After finishing his meal, Wang Jiankun left the recycling station and told them not to cook for him in the evening and let them arrange it themselves.

The 3-megawatt reactor in the underground base is still waiting for him to build, and Xingyao Electronics’ lighter production line expansion requires him to manufacture related equipment. School starts tomorrow, and the next semester will still be very busy.
