Zhang You is the general manager, and it is impossible not to have his office, but he rarely comes.

Not to mention, it's very clean.

Since someone makes tea and pours water, there is no need to elaborate, Zhang You sat on the sofa covered with thick cotton cushions, and pointed to the sofa next to him and signaled everyone with a smile: "Sit, sit down, it's not that you don't know me well, you don't need to be so restrained." ”

The object of these words is naturally Xu Guangqi and them, Guo Zaoqing and Xu Wei have already found their own seats to sit on, so they don't need to say it at all.

After the three of them were all seated, Zhang You said again: "Calling you over, the main thing is to talk about the instant messaging." In addition, I have to ask first, how far have our heaters go? ”

This matter is currently in charge of Zhao Zhenyu, hearing this, his already straight body is getting more and more straight, and said: "The progress is not too big, mainly facing two problems, first of all, the sealing of the piston is not easy to solve, at present, we are using animal skin, this thing is too easy to wear, if we can find a substitute that is not easy to wear, this matter has been ordered by their subordinates to do, but there is no good discovery for the time being." ”

After a period of exercise, Zhao Zhenyu has already lived up to his original appearance, with more calmness and calmness, watching him talk eloquently, Zhang You can easily connect with those social elites in later generations.

"Say it earlier, this matter is easy to solve, there is a material called rubber, which absolutely echoes your requirements, so you don't have to worry, I will write to Jiangnan when I go back, and ask them to send this thing over as soon as possible."

"Great, thank you, sir." Zhao Zhenyu was overjoyed, gearing up, and his face was flushed with excitement.

"What is there to thank, if you want to say thank you, I have to thank you." Zhang You smiled and said, "Now let's talk about the second problem, right?" ”

"Well, the second problem, according to our current technology, is not easy to solve. The heat engine already has the ability to generate power, but due to the limitations of the construction process, it cannot be made larger, which greatly reduces its practicability. ”

Zhang You quickly understood what he meant, pondered for a moment, and said, "This is really not easy to solve...... If only I could find a way to put the two steel plates together perfectly. Organize everyone to use their brains more, I don't have a good solution for the time being, but I believe that as long as you are willing to use your brains, there will never be a shortage of methods. ”

"That's right, in fact, Xiao Zhao and they also thought of what you said about splicing the steel plate, and they also came up with a lot of methods, such as using adhesives, and then splicing with molten iron, but unfortunately the effect is not ideal, and they can't withstand the huge hot gas pressure after heating." Guo Zaoqing interjected.

"Don't worry, this thing is an epoch-making product, how long have we been working on it? Take your time, and sooner or later you will be able to succeed. Zhang You saw that Zhao Zhenyu was a little upset, and cheered him up.

"When connected with molten iron, did you burn the edges of the two iron plates and soften them?" Xu Wei said suddenly.

"It's burned, the effect is indeed stronger, but this method is a bit difficult to operate, after the large steel plates are all burned red, the temperature is really not something that people can bear, and if it is small, it can't meet the requirements......" While saying, Zhao Zhenyu spread his hands, and continued: "If only there was a way to make the flame only burn the edge of the steel plate." ”

Zhang You had a flash of lightning in his mind, stood up slowly, and said loudly to a young man standing at the door: "Go find candles, and then go to the kitchen to see if there are goose feathers, and if so, pick up a few of them." ”

The young man obeyed the order, and the rest of the people looked at Zhang You in confusion, Guo Zaoqing asked, "What did you think of here?" ”

Xu Wei also said: "It can't be that I thought of any good way, right?" ”

The other three didn't speak, but looked at Zhang You expectantly.

"Keep it a secret, and you'll find out in a moment."

Xu Guangqi sighed lightly: "I knew that the adults would definitely sell Guanzi, and sure enough, they were guessed by the lower officials." ”

Zhang You laughed: "You know me well, don't worry, wait a while." ”

So everyone stopped talking.

The atmosphere was a little dull, Zhang You smiled and said: "It's boring to wait, Xiao Zhao, you go to find a few copper plates and iron plates one inch square, one or two millimeters thick, if there is no suitable one, let the craftsman do it on the spot, it won't take much effort." Then, find a little more copper wire, the thinner the better, a little thicker than a hair, like a copper plate and iron plate, if there is no ready-made, pull it now. ”

Gewu uses the same weights and measures as Zhang You, and thanks to the microscope, the unit of length can be accurate to the micron, which is the most advanced in the whole world.

Learned a lesson, Zhao Zhenyu didn't ask why, got up to look for it, and just when he arrived at the door, Zhang You stopped him again: "By the way, I forgot to tell the young man just now, you find someone to go to the kitchen and bring seven or eight potatoes over ......"

"What are potatoes?" Zhao Zhenyu asked curiously.

Zhang You patted his head: "Look at my brain, it's potatoes, didn't Alfled get a lot back some time ago, and he should have been divided, right?" ”

"Oh, potatoes, I did divide a lot, but I didn't want to eat them, a lot of them sprouted, Geng Sun said that Kaichun would get a piece of land to plant." Guo Zaoqing interjected and asked, "What are you looking for it?" ”

"Again, we'll find out later. Go Xiao Zhao, the best one to sprout, take ten or eight first, just say what I said, the provincial Geng Sun clan will not give it. ”

Zhao Zhenyu went out, everyone knew that Zhang You would not reveal his tone, although he was curious, he couldn't do anything, so he surrounded Xu Wei to discuss knowledge, I don't know how long it took, the young man in front finally found goose feathers and candles, and when he came in, everyone immediately stopped talking and all their eyes fell on Zhang You.

Zhang You didn't speak, lit the candle, and found a knife to make the goose feathers into a goose feather tube - forgot to bring a needle bag, otherwise there would be no need for such trouble.

The candle was lit, the flame jumped slightly, Zhang You washed the goose feather tube and put it in his mouth, moved a chair and sat in front of the candle, and said to everyone in a somewhat vague way: "Look at it, play a little trick for everyone." ”

Needless to say, the crowd had already gathered around.

As he spoke, he picked up the brush on the table, pinched it with one hand about an inch behind the candle flame, and gently put the other end of the goose feather tube into the flames and blew lightly.

The goose feather tube is very thin, although Zhang You did not use much strength, the air flow at the exit is not small, the flame that originally burned upward, under the surprised gaze of everyone, was affected by the air flow into a horizontal line, and the color also changed from yellow to light blue.

At the end of the line of fire was the barrel of the brush, and black smoke soon rose from the place of contact.

Seeing this, everyone's eyes suddenly lit up, and they suddenly understood Zhang You's intentions.
