You must know that before Ain came to Sunset Territory, he was already close to the strength of a senior architect.

He is similar to Yan Luo, although he can't find a particularly good job in the big territory, he definitely doesn't need to come to the sunset territory, which was once called a "ruin".

In order to be able to realize her desire to be in full control of everything and to be able to actively control her funds.

And the same is true of Ain, who is also trying to find a place where he can show his skills and not be dictated by people who don't know how to do it at all.

In fact, joining the Sunset Territory was an adventure for Ain, after all, he came before Ranluo.

At that time, the sunset territory could not be compared with when Yan Luo came, and when Yan Luo came, the territory had finally developed, and the natural disaster had come to an end.

But when Aine came, the territory was about to face the threat of natural disasters, but he decisively chose to join the territory for Su Yu's promise.

Because of this promise, Ain was also ordered to take over all the building-related burdens in the territory, and also played an important role in the maintenance of the buildings destroyed by acid rain during the natural disaster.

For those who are capable, what they hope for is always not to have the self-righteous guidance and pickiness of the superiors, which will seriously affect their enthusiasm for work.

Sunset Territory is not the best territory at the moment, but it is the most suitable territory for them, and it is the best territory in their eyes.

All this also has a huge relationship with Su Yu's attitude towards the residents.

For the inhabitants of the territory, for the people she entrusts with important tasks, her main focus is to use people without suspicion, not to suspect people, she will never point fingers at their work, let alone self-righteous guidance, nor will she exert too much unnecessary pressure.

Of course, this may also have something to do with the fact that she has a digital system, because she can see the loyalty and friendship points of these people and their strength, so she knows whether they are trustworthy and qualified.

As long as she is trustworthy and has passed the test, she will basically delegate power.

But Su Yu never interferes in their professional matters, and only participates in more critical and important matters, such as the execution of the investment business that Yan Luo said yesterday.

Having such a lord is definitely a lucky thing for most people, especially those who have the ability and dreams.

Because here, they can realize many of their dreams without worrying about dying halfway due to human factors.

……

……

Back to the point, after communicating with Ain about the city wall, Suyu went to the blacksmith shop and the machine shop again.

I went to the blacksmith shop to let Canglan make the 'large crossbow arrows' used in the city defense crossbow, and I went to the machinery shop to give An Jie the drawings of the city defense crossbow and catapult so that he could be in charge of making them.

Although large crossbow arrows are certainly more difficult to craft than ordinary arrows, they are not difficult for Canglan, who can be upgraded to a high-level blacksmith right away.

But the city defense crossbow and catapult are obviously not so simple.

These two big guys need to use medium and large parts, and An Jie has just been promoted to the intermediate level, although he can already use these two parts, but he is not very proficient.

The consequence of unskilled use of parts is that certain problems may arise in the process of assembly, and these problems may be exposed in the process of assembly, and may also be exposed in the process of subsequent use.

If it's the former, it's a big deal to assemble it again, it's just a bit of a waste of time.

But if it's the latter...... It's like in the middle of a battle, and instead of firing bullets to kill the enemy, the gun in your hand explodes and kills you.

Therefore, Su Yu was very strict when explaining the production of catapults and crossbows.

She even spent most of the day in the machinery shop, watching An Jie assemble step by step, until she made the first catapult and the city crossbow, and then she was relieved.

Although Su Yu is not a professional mechanic, she has seen a lot of mechanical equipment, and she still understands some relevant basic knowledge, plus she can still see the information of these two mechanical equipment, so she can also see that there is no problem with the quality of the first catapult and the first city-guarding crossbow.

"In three days, I need you to make at least four more catapults and four more crossbows." Together with the existing one catapult and the city crossbow, there are a total of five catapults and city crossbows.

"No problem!" An Jie guessed that there was not only one catapult and city guarding crossbow that he needed to make, so he had calculated the time to make this catapult and city guarding crossbow before.

The difficulty of the catapult is lower than that of the city crossbow, but it requires more parts, because the stone is a heavy object after all, and more parts are needed to support the operation in order to achieve the effect of the stone throwing.

Therefore, the parts of the catapult take an hour to make, and the assembly takes two hours, which adds up to three hours.

The crossbow is the opposite of the catapult, there are few parts, but it is difficult to assemble, because the most important thing for the ballista is the accuracy of the crossbow arrows fired, if the assembly is not careful, then the launch position of the crossbow arrow will be offset, and the firing power of the arrow will be insufficient, resulting in a drop halfway.

As a result, it took half an hour to make the parts of the crossbow and three and a half hours to assemble, for a total of four hours.

In this way, these eight large machines consume a total of 28 hours, and the average of three days is more than nine hours of work per day.

It looks like a lot, but the actual speed will be faster.

Because the parts of the catapult and the city guard crossbow are universal, Anjie does not make only one part at a time.

If he's lucky, he can make more parts in the same amount of time, which shortens the time it takes to make parts.

Not only that, but the assembly time is not constant, but decreases as proficiency increases.

According to An Jie's calculations, he was able to shorten the original 28 hours of work to 25 hours, and if he was lucky, 24 or 23 hours was also possible.

As for overtime, the best working condition for a mechanic is eight hours a day...... Ten hours at most, any more will affect the efficiency and quality of work.

An Jie knew that the lord valued quality, so he didn't mention anything about overtime, and it was thankless.

"My lord, I think I can at least make one more catapult or a city crossbow, which one do you think you need?"
