Just when Zhou Cang and the others were busy starting to suppress the bandits, Bai Yang had a good rest in the mansion. Boxing and shopping every day, I felt pretty good at first, but then I couldn't stay a little bit. I felt that I couldn't do nothing like this every day, so Bai Yang began to think about it again after resting for two days.

Thinking about it, there are a lot of things that need to be done now, but if many things are implemented now, they will feel inappropriate because of such and such problems, and sitting at home seems to be able to teach children to read and write, and they can only think about inventing something.

After thinking about it for a long time, there are actually two things that are quite important to him:

The first is the source of funds in the future, originally according to Bai Yang's idea is to invent some daily necessities, and there will be no worries about life in the future. Although there is still a lot of money now, it is not a matter of sitting on the mountain like this.

The second is that I have been in the Eastern Han Dynasty for so long, especially in the training of the sergeants, I feel that I can't always convert the time with modern generals. It's good that he always brings a mechanical watch with him, and he knows the specific time of day. But it is a little inconvenient to communicate with other people, and I have to ponder for a long time in my heart to figure it out, and the time is too unspecific, at least it can be specific to a quarter of an hour, and then there is no way to accurately time.

And many people don't have a strong concept of time, in the subsequent special operations training, it is a race against time training, this is not good, now most people in the house still wait for the shift every day to know the approximate time.

"Let's find a way to figure out a mechanical watch, and when the time comes to match the jet lag with my watch, it should be no problem to observe for a few more days. But how? The current technology is too backward, or the whole winding mechanical watch will be solved by letting the sergeants wind it every day. Bai Yang pondered and pondered, and if he didn't want to, he would design it out first.

For mechanical watches, Bai Yang still knew a little bit before, maybe he didn't know too much, but he was confident that he would try a few more times to roughly complete a simple one.

I walked to the study and thought about it, first remembered its principle, and after removing some parts for beauty or superfluous, I probably had a blueprint in my heart.

In fact, mechanical watches are mainly divided into two parts, one is the movement, and the other is the exterior parts. In fact, to put it bluntly, the main difficulty is the movement, and the appearance parts are just a matter of whether they look good or not.

The movement mainly includes the drive train, the prime mover system, the upper dial system, the escapement speed control system and the hands system. To put it clearly, the main point is that the gears and barrels are the most difficult, and the gears are exquisite in size and uniformity. The difficulty of clockwork is mainly due to the fact that there is no such excellent technology now, and the iron-burning technology of this period is too poor, and if you want to solve this problem, you must reach the level of 'steel'. It is also a shame that yesterday Sun Chen reported on their steelmaking situation, and now it has been greatly improved.

For the sake of steelmaking, Sun Chen has looked for Bai Yang many times, and Bai Yang later went to the Ordnance Department several times to observe and inspect the situation according to Sun Chen's introduction and the actual situation, and put forward some new ideas for the next experimental work many times, thinking that it will not take long to have a leapfrog progress.

Now that I think about it, Sun Chen's side is not in a hurry, and he can prepare to make some gears first. Bai Yang thought of this and began to do it, at first designed some small gears, and then thought about how there is the technology to make such a small watch, this small is not small, the smallest estimate is about half a meter to add the shell.

"It seems that the whole small one is a bit choking, and technology still limits the development! In the future, pay more attention to some scientific research and technology, people and craftsmen, etc., and find ways to give Sun Chen more people. Maybe in a few years, you will be able to make a mechanical watch that is more than ten or twenty centimeters large, and it will be much more convenient to march and fight at that time, and now the whole half meter is not of much significance. ”

"Since it's small, it's better to make a big one directly, just like the big watch in the later train station, school and other places, you can directly build a large watchtower in front of the training ground, which can usually be used by soldiers to monitor the situation around the Taishou Mansion, and a large mechanical watch can also be hung on it. It just so happens that when the sergeants are on duty, they can regularly wind the mechanical watch, and I am not too smart. Thinking about it, he smirked, and felt like a genius.

After thinking about it, I found some fabric and began to write and draw, and spent a whole day drawing the appearance of gears and some other parts.

"Little Green Willow, go to the Ordnance Department and ask Minister Sun to come to me." Bai Yang shouted outside the study.

The little green willow is fifteen years old, and he has clear eyebrows and beautiful eyes, and the elders see that Bai Yang's busy feet don't touch the ground every day, so they let the little green willow follow him, and he can usually run an errand or something.

Little Green Willow has been with Bai Yang for more than two months, and her performance is very good. Usually I mainly serve a meal to Bai Yang, call someone and other work.

Bai Yang usually asked her to go into the study to wait for him, but the little girl was very stubborn, and she didn't know where she heard others say that the study was generally a place with more secrets, but she didn't enter Bai Yang's study. I begged the old man to find someone to build a small shed outside the study, and I looked like a secretary of a large company in my previous life.

"Yes, sir." After the little green willow agreed, he heard the sound of footsteps hurrying towards the distance.

After a short time, Sun Chen came to Baiyang's study, looking at a table covered with all kinds of coarse cloths painted with strange patterns, the first thing that came to Sun Chen's heart was: The elders are estimated to have been distressed for a while.

"Minister Sun, you have worked hard with all the craftsmen and masters tonight. Make a round discus in all the sizes I give you, it must be round, and the thickness must be according to the size. Try to get it to me tomorrow morning, I'll be useful. ”

Bai Yang said and gave Sun Chen a coarse cloth full of numbers, thanks to teaching everyone simple numbers some time ago, otherwise this data is written on the coarse cloth, it is estimated that two people will have to carry it.

Sun Chen looked at it, thought for a while, and said, "No problem, lord." I'll send it to you early tomorrow morning. ”

"Well, that's good, there are not enough people to find the elders. You can transfer some people to him, but if you can't do it, you can go to Zhou Cang and transfer some sergeants to help. ”

"It should be fine."

"That's good, there's another thing, how is the steelmaking experiment that made you toss some time ago?" Bai Yang saw that there was indeed no problem and asked about steelmaking, which was a particularly crucial part of his plan.

"My lord, I was about to report this to you. According to what you said, we organized a few people to really find coal in the area of Ziyun Mountain. With this coal, the heat of steelmaking is much stronger, and the sustainability is particularly good. After the steelmaking tips and methods mentioned by the lord, our current steel has reached about 60% of the original requirements of the lord. I believe that there will be a greater improvement in a period of time, and our Ordnance Department is confident. Sun Chen replied happily after listening to Bai Yang's words.

Bai Yang was also very happy to hear this, and now the level of steel has almost reached the texture of making clockwork.

"Haha, Brother Sun, it's really yours. Okay, that's good. The weapons made of our current steel are also three or four times the strength of the Han standard weapons, which is very good. In this way, you will go to the elders and receive a thousand taels of silver, and give it to our brothers in the ordnance department according to how much you contribute. Tell them to do a good job, and I will reward them for their achievements in the future. ”

"I take my brothers from the Ordnance Department to thank my lord."

The next day, Bai Yang asked the elders to call some people. The painted gears were pasted on the discus sent by Sun Chen, and everyone began to polish the gears according to the size of the discus or one or more people according to the drawings.

This is also a way to do it, there are no machine tools in the Eastern Han Dynasty, and this precision requires a high level, Bai Yang can only use manual production, and he is running back and forth between the people to guide.

After three days of grinding, the gears were finally ready. Bai Yang began to have everyone polish the hands again, and instructed the two carpenters to make a wooden shell with a lid. There is no way, because there is no glass or plastic, Bai Yang can only add a cover to the outside of the watch, which can usually be left uncovered, and everyone can see it. Closing the lid in extreme weather can be very protective.

After that, Bai Yang plunged into the ordnance department and tossed with a few old blacksmiths, and it took two days to finally make the last part of the 'clockwork', Bai Yang tried the strength of the work, put it in the clockwork box and walked towards the training ground with a group of craftsmen.

There was a group of people waiting there very early, and the elders, Liu Yijian and others made way for Bai Yang, and Bai Yang began to command everyone to assemble it.

"Old Liu, it's not like this, you put that gear upside down. These two gears can't stand it now, it doesn't work, you see that this one turns and that one doesn't turn. ”

"Elder Li, you can't put the No. 3 gear and the No. 5 gear in it, and the two can't get together. That Minister Sun, the shortest needle is installed first, and the longest needle is loaded last. That's right, it's the red one, these two calibers are different, no matter how hard you try, it won't work. ”

"Elders, if you knock the bottom of the box and reload it, it must be crooked."

"You go and plug the hole in the box and find a little plank to fix it. Such a big opening, and the parts inside were destroyed in a few days. ”

Bai Yang instructed everyone to work while checking whether there were any mistakes, and finally installed the first mechanical watch made by hand in the Eastern Han Dynasty with the concerted efforts of everyone. How to say it, it's huge, and the watch is more than three meters tall even with the shell, which is simply a giant.

Looking at the installed mechanical watch, Bai Yang instructed the two of them to correct the pointer and the mechanical watch they were wearing. Then he found a pole more than ten centimeters long and shook it vigorously with Sun Chen, and after about seven or eight laps, Bai Yang pulled it out.

Suddenly, the sound of "tick, tick, tick, tick......" suddenly came from inside.

Bai Yang suddenly felt his heart beating, and while looking at his mechanical watch, he stared at the second hand of the big mechanical watch and counted the numbers silently in his heart.

Time seems to be frozen, everyone doesn't understand, just stretch their necks and look at it.

"Tick, tick, tick......" A minute, three minutes, five minutes passed in the blink of an eye. Bai Yang finally waited for ten minutes, and suddenly raised his hand happily and shouted: "Haha, hahaha, it's successful!" ”
