"Don't worry, Ruoruo, slow down, you're a person with a body, be careful in your actions. When you get home, don't do it yourself, and when you go for a walk, you have to be accompanied by someone......"

This is unlucky, Zhang Han gently hugged Ruoruo, his heart was full of pity. Since he wants to have a career, it is impossible to spend much time on his daughter, but it still makes him feel a little guilty that he will have to go out to study soon after he is pregnant. However, the matter is imperative. Zhang Han also has nothing to choose, he can't be by Ruoruo's side. In this life, his Zhang Han's woman is destined to be unlucky......

"Okay, okay, I know, young master~

How is this car not bumpy at all......"

When I heard Zhang Han say it for the first time, Ruoruo was full of joy, but this was the first dozens of times, and Ruoruo couldn't help but have a little headache, so he quickly found another topic. However, the carriage was really not bumpy today, and she stretched out her head to look down. Naturally, she didn't see anything.

"This car, naturally, Lao Wang drove it well......"

Zhang Han pulled Ruoruo back, but played a trick. If she snorted, she would have to withdraw her hand from Zhang Han's hand, she would not say that Lao Wang was not good at driving, but this was obviously not true, no matter how good Lao Wang's car was, it would not be so stable. Zhang Han hurriedly clenched, Ruoruo is very good at pinching people. Ten fingers were entangled, and after a while, Zhang Han opened his mouth to explain.

"This car is not a ...... directly on the axle" - Zhang Hanren tried to install leaf springs on the axles, and put the carriage on the springs, so the vibration was much smaller. The small workshop has just been successfully experimented, and this experimental car was pulled by Zhang Han to use it. In this way, it is much more comfortable, but the price is extremely high. The crucible steel used in the two leaf springs is enough to make more than a dozen treasure knives, and the value is dozens of times more expensive than the carriage.

Naturally, there is no need to say much, Zhang Han is easy to come, so he doesn't care. Anyway, when you need it, you can refine it again.

The small workshop was moved to Bian Nan in the autumn of the second year of Xiping (173). From April of the second year of Xiping, more than a dozen blacksmiths were concentrated to produce steel filling for the soldiers, and it was not completed until the autumn. The quality of the steel filling varies slightly with the craftsmanship of the craftsman, but on the whole, it is much better than the quality of the fried steel. As a result, the soldiers' weapons were quickly replaced.

Subsequently, these blacksmiths moved to Bian Nanzhuang with their families. It's a pity that Zhang Han couldn't get Wang Guanquan, Wang Guanquan was one of Zhang Tingfang's stewards, Zhang Tingfang refused to let go, and Zhang Han had no choice. There, a small workshop had been built, and Zhang Han prepared a house for them, a blast furnace, a calciner, and a small open hearth. When they moved to Bian Nan, they could work directly. Zhang Han has a lot of ideas for them to realize.

Iron wire, Zhang Han knew that the iron wire was pulled out, and an iron rod was drawn into a thinner iron rod through a slightly thinner hole; The previous process was repeated repeatedly, and finally the wire was obtained. With iron wire, iron nails can also be produced. Both have a wide range of applications, and Zhang Han attaches great importance to them. It's not hard to draw by hand. However, the wire drawing machine that Zhang Han plans to manufacture is a difficult problem, and how to realize it still needs the hard work of craftsmen.

Lathe, Zhang Han only knows, to rotate the workpiece stuck on the lathe, and then cut with a turning tool, how to achieve it, what kind of structure, really don't know. To be honest, Zhang Han himself knows that with his level of knowledge, it is estimated that it will take hundreds of years to build a modern lathe. However, this thing is the way of the future. Zhang Han talked about the structure and function of screws, screws, gears, jinglun, and bearings, and announced that he would put aside the research that could be studied. Shenggu was happy to lose, Zhang Han comforted himself like this. As for whether it will be "happy" or "happy" at that time, Zhang Han can't care so much.

The improvement of textile machinery is also one of the key projects. Food, clothing, housing and transportation, clothes come first. Moreover, in the Han Kingdom, cloth was directly used as money, and Zhang Han was certainly interested in the minting industry. Unfortunately, he did not know the structure of modern textile machinery, and he had never even seen it. Therefore, all improvements can only be made on the basis of existing machinery.

After a few days of visiting how the jacquard loom works, Zhang Han decided to leave it to the professionals. Of course, he didn't raise any opinions. At the very least, Zhang Han proposed the silk ingot. The silk is wound around a thin spindle at the top and thick at the bottom to form a silk spindle. Then, the silk spindle is inserted into the collar to weave the cloth. A skilled woman's weaving efficiency immediately tripled, from two feet a day to six or seven feet a day. Taking into account the labor required for the spindle, the efficiency is still more than doubled. Moreover, Zhang Han also proposed the use of water power and increased the number of spinning wheel spindles. However, this involves the structure of the spinning wheel and the loom, which cannot be completed in a short time.

In addition, pulleys and sheaves are simple in structure, quickly manufactured, and quickly applied to lifting heavy loads. Small tools such as saw bows, saw blades, grinding wheels, files, pliers, planers, etc., are also manufactured in a short period of time and used in various workshops at home.

The work of the small workshop is very important, and the remuneration is naturally very good. Zhang Han's people from all over the house are all young, strong, and skilled craftsmen, and he will not treat them badly. The houses he prepared for them were all red brick houses, and biogas stoves were generally installed. Other aspects of treatment are also higher than before.

If there is a pregnancy, Zhang Han is careful and careful, the carriage wants Lao Wang to drive very slowly, and he sets off early in the morning, but he does not arrive at Zhang Wu until the next evening.

After settling down, Zhang Han took some time to arrange other affairs properly. There is Zhang Jian in charge of daily affairs, there is servant training, there is a steward Li Shengzhong in the small workshop, and Zhang Tingfang is in the smelting workshop.

"These are gifts for your grandfather; These are for your grandmother; These are for your two uncles; These are for your father-in-law; These are the ...... for Ah Eye."

Zhang Wang pointed to the dozens of cages on the ground and explained them to Zhang Han one by one. Ah Yan is Zhang Han's fiancée, it is said that she has a pair of beautiful big eyes, so Wang Lie is named Eye.

"And these, a change of clothes for you to take with you, and some necessary utensils."

Zhang Han sweated, how could he bring such things.

"Mother, are you going to move the Zhang family back to the Wang family?"

Zhang Han made a grief-stricken appearance and whispered.

"Oh, too, or else, don't bring any of these......"

Zhang Wang casually pointed to the gifts that Wang Lie and Ah Yan brought.

"Uh...... Forget it, the Zhang family and the Wang family are not a family yet, so it's good to move there......"

Zhang Han waved his hand, very heroic.

"Bang~"

Zhang Wang was angry and funny, and knocked Zhang Han's head hard.

"Everyone else has married a daughter-in-law and forgotten their mother, but your daughter-in-law hasn't married yet......"

"Hey, hey, hey......"

Zhang Han pretended to be stupid.

"Alas, the baby has grown up, and he wants to marry a daughter-in-law, and he is old for his mother, and no one wants it......"

Zhang Wang pretended to sigh and reached out to rub it on his son's head, just as he used to do when he was a child. Zhang Han did not stop it, at the mercy of Zhang Wang's family, since he moved to Bian Nan, it has been a long time since the mother and son have been so intimate. At this moment, Zhang Wang's made such a move, Zhang Han's heart was warm, and he looked at Zhang Wang's with a smile. The sun shone obliquely on her snow-white face, crystal like jade, and she couldn't even see the wrinkles at the corners of her eyes if she didn't look closely, and there was a trace of old age.

……

At the beginning of April of the third year of Xiping (174), Zhang Han was sixteen years old and officially left home to go out to study.
