When Uncle and Lao Liu left again, Yang Heng suddenly found a problem, that is, the problem of shock absorption was only half solved, that is, the car still needed to be changed.

How to change, that is, the place where the wheels need to be fixed, add two thicker iron plates, and then add two steel plates below to absorb shocks, this steel plate is made of Yang Heng's secret recipe, after quenching and other processes, it can still play a certain role, although this kind of steel is used to make spring plates, it is somewhat inconsistent, but this is to spare two steel plates.

In this line of thinking, Yang Heng suddenly found that there are many places for the transformation of this car, not only to add a place to hang spring plates, but also to install a few places to put spare parts, which count two spring plates, three pairs of wooden wheel outer rings, others such as several dustproof sealing rings, and some pins, and most importantly, there should be some chariot maintenance workers in the army, which also needs Yang Heng to personally train.

Maintenance workers, this also has to be selected in this team, maybe this is the ancestor of vehicle maintenance in the future, and it is not that there are no people who repair carriages and ox carts before, but those people are carpenters, not maintenance workers, now, this maintenance worker will become a specialized profession, and even in the future, with the increase of mechanical things made by Yang Heng, the profession of maintenance workers will shine.

"From today onwards, you will enter this room one by one, and I will evaluate you." In order to find out who can be a maintenance worker, Yang Heng has put a lot of effort into it.

How to choose, this can't be said to use a kind of mass type of exam, to say that in a large square to open the shelf, each person has a car for maintenance, now Yang Heng does not have so many cars for the soldiers to repair, so he used a group of ten people to test, he personally sat in the formation, that is, let ten soldiers assemble a car together, and before the assembly is disassembled, first disassemble the car, and then assemble it, then naturally know that the soldier is the person Yang Heng needs, It's a bit troublesome to use this method, but Yang Heng still has a plan, that is, if this fire really has no interest in this, Yang Heng won't let them continue, you must know that Lu Dao sometimes can't pick out a single person between several fires or even dozens of fires in a row.

"Let's take a moment and let me take a look." Finally, Yang Heng's eyes lit up, this should be a skilled talent, although a few were picked out in front, but they were all a little reluctant, but this one was too brilliant, he actually knew that Lu Dao first took a good look at a car, and then decided how to dismantle it, and showed strong self-confidence in front of this car, and even other soldiers listened to his command, to know that Lu Dao was not a fire chief.

"Okay, I'm done, now I'll arrange your work, you are in this place, you are here, you two assist me, you two each find your assistants, and the rest are responsible for observing on the side, if we make a mistake during installation, you have to remind you in time."

This, this, this, this is a maintenance genius, and even some command talents, Yang Heng immediately decided, this fire people want it, just rely on their cooperation, and this soldier Yang Heng who made Yang Heng's eyes light up in front also decided, if there is no better character than him in the back, then he is the brigade commander of this maintenance brigade, Yang Heng is now planning to find out a hundred maintenance workers first, and then train them collectively, and then they can take up their posts.

However, the people of this brigade also have a task, that is, they are responsible for carrying a large number of vehicles, as well as the accessories of bows and crossbows, and even the weapons maintenance industry of the whole army is their job, naturally, Yang Heng will also equip a few blacksmiths, but this blacksmith needs to be transferred by Li Er from another place.

"Major General, there are two people, one of them is your uncle, they have been asking to see you outside the camp for a few days, and I didn't come to inform you because I saw that you were busy assessing the soldiers."

"Uncle." As soon as Yang Heng heard it, he knew that the uncle was coming, although he regretted it in his heart and didn't let the uncle in time, but there was no way to do it, no matter what kind of mess, he needed to be there, and he couldn't be divided into two or more people to work, if someone shared it, ah, yes, there was a share.

"Come on, call me the one in front of you, it's the fire that has been selected as a whole." At this time, Yang Heng realized that he didn't know what the name of the soldier he recognized was, and these people were all recorded by a clerk.

"Major General, you called us." "Well, you're that, what's your name?" "Back to Major General, the little one's name is Tian Cheng." "Oh, Tian Cheng, yes, you will take my place next, responsible for assessing the ability of all soldiers to recognize and understand vehicles, that is to say, I need to select some maintenance workers to repair this kind of vehicle, and you are responsible for finding out the right candidates."

Yang Heng quickly handed over the matter to Tian Cheng, and he knew that Tian Cheng would handle this matter well. "Don't worry, Major General, I will definitely take care of this matter." Even so, Yang Heng still asked the clerk to be responsible for selecting the repairman with Tian Cheng, if he wants to be familiar with this process, the clerk is much more familiar than Tian Cheng, because the clerk has been by Yang Heng's side for a long time, so Yang Heng still trusts the clerk more, but some things do need to wait for someone to operate.

"Uncle, and Lao Liu, you're here, I'm sorry, I've been busy looking for repairmen these days, this army has this chariot, but if there are no repairmen, it won't be able to play its biggest role." Yang Heng apologized to the two of them and took the two to his studio.

"Come, Lao Liu, uncle, this is my last change, and then it should be officially put into production, you look at this place, and this place needs to be ......"

After a while, Uncle Xiao and Lao Liu left with the drawings again, and they didn't feel troubled, but left with the mood of participating in important things. Anyone knows that the appearance of a thing is not so smooth, if it is smooth sailing, then the value of this thing is not so great, this is the idea of Uncle Xiao and Lao Liu. But Yang Heng's thoughts are just the opposite of the two of them, he has been condemning himself, why didn't he think of some things, if he had thought of it earlier, it wouldn't have been so troublesome, seeing, this year has passed again, and he has achieved nothing until now, but now he has become a family man, and even Yang Heng still feels funny, this hair has not grown, you can marry a daughter-in-law, looking at Li Er's anxious appearance, it is estimated that this daughter-in-law will enter the door next year.
