"Sister, what good cosmetics has my eldest brother used for you these days, your complexion is so good these days." Yu Zhang stroked Changle's face and said enviously, and even slowly touched his hand to Changle's twin peaks.

"Get out, you little pervert, can you touch this place, what cosmetics, no cosmetics, can't you do it without you." As he spoke, Changle blushed a little.

Yes, this first taste of meat, Yang Heng still ploughed the fertile field, and used the thick slurry to irrigate vigorously, so, this fertile field is not more fertile, it is really unreasonable.

"Haha, I know, it must be you and eldest brother, sister, when will I be able to get married, can you tell my father and let me marry soon."

"You are a little perverted girl, even if you get married, you can't do anything with your husband, the rules of our Yang family are that men and women must be eighteen years old before they can have sex together, don't you see that I have just reached eighteen years old, okay, okay, you don't have to think about it, you wait slowly, it's really boring, just care more about your industry, I have to care about my industry, I will give it to my baby in the future." Changle stroked his stomach.

"Sister, you have a baby, let me touch it, let me touch it." "I don't know, there will be somewhat, isn't it, Xianggong is so strong." Changle said happily.

"Big nephew, what are you busy with these days, many people in the city are urging me to buy which clock." Uncle really had no choice, so he had to come to Yang Heng in person.

This young man and woman, who tasted meat for the first time, still haven't enjoyed it to the fullest. Nature. Yang Heng even left everything else behind. I know that I am with Changle all day long, not to mention the red face and trouble, it is really good.

"Ah, okay, I'll check it out right away." Yang Heng said with hazy eyes, this, Changle was full of red light, while Yang Heng was a little haggard. Sure enough, there were only tired oxen, and there were no rotten fields.

"Big nephew, what are you busy with these days, you can't do it in this state, then I'll go first, you must hurry up and find a way." Uncle didn't know anything about Yang Heng, he was always on the construction site, and sometimes he would go into the city to do some things, so someone asked him about the clock. Originally, Yang Heng wanted to build a watch factory. This kind of thing and that kind of thing was delayed, and this factory was not built. It's just that those gold, silver and coppersmith technicians are still making it, which is naturally much slower.

"Oh, is this still me, no wonder Changle wants to give a tonic, it seems that it has to be controlled, otherwise, my little body will be ruined." Yang Heng looked in the mirror and felt very scared, in fact, this was also the reason why he hadn't slept well these days.

"Come, masters, you stop what you are doing first, and we will do something else first." "Ah Lang, this can't be done, didn't you tell everyone that you should deliver the goods as soon as possible, if you stop, it will delay time." "Haha, it doesn't matter, it doesn't matter, I just promised to deliver as soon as possible, not to promise them when to deliver, just to speed up this manufacturing capacity, I asked you to stop, we have to make some machinery and equipment now, to replace this purely manual work, otherwise, at this speed, what money do we make."

Yes, Yang Heng needs these technicians to manually process some machinery to manufacture a clock production line, or even a few production lines, however, these production lines are not entirely for a kind of clock, he needs to make a table clock, wall clock, alarm clock, and even pocket watches, watch production lines at one time, which takes a lot of time, the rough processing of some workpieces can be handed over to those large lathes and red furnaces to manufacture, and finishing needs to be precision grinding by hand, which is a time-consuming job, Yang Heng even gathered dozens of technicians in the mountains to manufacture together, and they even brought dozens of students, which is a strong public relations team.

If it is said that the manufacture of some powerful precision machinery, at this time, it is really impossible to manufacture, but if it is to manufacture a single-function precision machinery, it is entirely possible to manufacture, Yang Heng found these technicians, that are the existence of top talents, for example, they use the vertical thread sling, which is made of the finest silk, this silk, quite symmetrical, and very fine, very strong, under the condition of no wind, will achieve a 10,000th degree of accuracy, and, among these technicians, there are several jewelers, That is the existence of the existence of silk-level miniature carvings without using a magnifying glass, and only in ancient times, no matter how top craftsmen are, they will not be particularly valued, that is, Yang Heng can collect them and make full use of them.

These people, in the past time, at the request of Yang Heng, not only made vernier calipers, but even made micrometers, and the micrometer has reached an accuracy of 0.1 millimeter, and the vernier caliper has also reached an accuracy of 0.2, naturally, this Hao is different from Yang Heng's Hao in his previous life, he selected a hundred sesame seeds, and selected most of the sesame seeds of the same width in this hundred sesame seeds to be regarded as a milli existence, that is to say, At this time, weights and measures have given up on using a certain part of someone as a meter, but have converted it upwards with this howe as the basic unit.

While arranging everyone to grind the machinery, Yang Heng is also making some small motors, because these machines are all small power machinery, naturally, it is completely suitable to use the motor as the power, and the machinery driven by the electric motor, in the case of light load, the speed is constant, and there will be no accidents.

Motors, although the silicon steel sheet has not been fully developed at this time, the steel sheet with higher permeability than the ordinary iron sheet has been available, Yang Heng is using these semi-finished steel sheets to manufacture the motor, in this way, the iron consumption and copper consumption of these motors are much less, and the efficiency has also improved a lot, Yang Heng estimates that for a long time, this kind of motor will become the mainstream existence.

A month later, the first watch production line was officially completed, and after Yang Heng made it from beginning to end, the technicians quickly assembled these parts into clocks one by one.

"Ah Lang, this, this is too fast, in just a moment, ten clocks and watches have been successfully manufactured, it's incredible." The technicians were stunned.

"Okay, okay, what's so surprising about this, if it weren't for this efficiency, I would have asked so many of you to put down your work and come to public relations, but don't disband your gang, and from now on, form a precision machinery laboratory."

So, in the academy, a new renovation began again, but it still had to come as needed, and this precision machinery laboratory was the first large-scale laboratory.

And this set of clock production line is also the first real production line in Yang Heng's hands, and in some other factories, a machine tool still needs to process a variety of parts.

"Don't stop this task of manufacturing machinery, but don't be too anxious, now you must first teach the personnel I sent, so that they can become qualified mechanical operators, otherwise, this watch factory can still let you continue to work in it, isn't that a big deal."

In the past, when the family industry was streamlined, there were some old workers, and some trustworthy workers, who were idle, so Yang Heng temporarily put them in some factories as helpers, waiting for a suitable place to place them, although they were old workers, but their age was not old, but it was said that they were relatively early in Yang Heng's home, and now these people are suitable to be arranged in this new factory.

Yang Heng believes that now in his home, not to mention that there are no outsiders' spies at all, it can be said that the existence of outsiders' spies can basically be eliminated, that is, in terms of railways, it is a place that cannot be completely cleaned up. However, in that place, there is no need for Yang Heng to worry, Li Er will arrange for someone to clean up some people who shouldn't be, you know, this railway is the most important thing for Li Er.
