Li Hongru never expected that there would be such a huge casting site in the Chang'an City area.

There are areas on the ground and areas on the ground.

Many skilled craftsmen gather here.

There are those who sew inner armor, those who build equipment, and those who make various drugs, and there are also many strange props.

This is the supply office of many Yulin Army armor in Chang'an City, and it is also the equipment collection office for members of Dali Temple and other departments.

In each state, there are equipment departments like Chang'an City, but their sizes are different.

As the capital of the Tang Dynasty, Chang'an City undoubtedly gathers the strongest group of skilled craftsmen in the world.

Li Hongru looked up and saw two half-man-high equipment flying around in the air more than ten meters away.

This is a bit similar to the prototype of a helicopter.

But the power of the instrument seems to rely on gears and belts and cannot last long.

The propeller speed, which was like a bamboo dragonfly, decreased, and this simple aircraft gradually fell down.

"This is a liftoff device. Although it is magical, it has no effect at present and is difficult to come in handy."

Seeing that Li Hongru was a little interested, Xu Maogong commented.

The lifting device is not very useful to those with great abilities, but it is difficult to assist middle-level practitioners. Their abilities seem extremely awkward, and they are bulky and difficult to carry, so they have not been used in any way.

"If you fall into a deep pit, you can still fly out on this lifting device," Wang Fuchou said with a smile.

“I feel it will be more convenient to pull the rope!”

Some instruments are indeed difficult to use in the early stages of their inception.

Xu Maogong thought about it and felt that it was difficult for the army to use such equipment.

The liftoff has some advantages, but compared with the advantages, the defects of this prop are too serious and more improvements are needed.

There was no engine at this time. Li Hongru looked at the liftgate and felt that the only way to use this type of product is to use manpower.

However, everyone has different physical strength and strength, and taking off is too dangerous. We must prevent the impact of weather and unexpected things. This will be a test for designers and experimenters.

Li Hongru also saw a craftsman wandering around on a wooden wheelbarrow.

This is also a very useless design.

Wheelbarrows can only run on flat ground, and it is easy to overturn when encountering bumpy terrain. If you encounter wetlands, you will fall into the ground again.

If there is a horse, this kind of wheelbarrow has no market and can only be used for entertainment.

"Ga, I am Wang Dali's bird. The weather is very good today and it may rain in the evening."

An extremely realistic wooden parrot opened his mouth and began to regularly push today's weather.

Li Hongru was quite interested and did not understand the principle of speaking out for a while.

"Don't touch Wang Dali's bird!"

As soon as Li Hongru touched it, he saw the bird flapping its wings and screaming, and immediately withdrew his hand back in disappointment.

"Sir, that's it."

Siye, who led the way, walked to the workshop where the wooden parrot was located and stopped.

"Wang Dali is the most skilled craftsman in the Equipment Department. Look at this little wooden bird, its bird's belly has many skillful things."

Si Ye pointed to the workshop and introduced Muniao to everyone, then raised his hand and slapped the door.

In addition to some manufacturers who need to open the doors and assembly line, many workshops have closed doors, allowing craftsmen to think about it with peace of mind.

This is an analyses research institute in the Tang Dynasty, and it also continuously moves forward military and people's livelihood technology.

When Li Hongru was looking at the bird, he saw that the door of the workshop was opened and a big man with a beard rushed out angrily.

He was about to get angry, but he saw that the other party was Si Ye, who was rarely seen in the Equipment Department, and he immediately turned to a smile.

This is a big shot, otherwise it would be impossible for Si Ye to lead the way.

"No wonder I feel the voice is a little unfamiliar. It turns out that Lord He is here. Are you asking me for something?" Wang Dali said with awkward smile.

He looked at Xu Maogong and others behind He Siye, and felt that these people were all of them with extraordinary temperament and had a big background.

"Mr. Xu wants to polish two crystals, see if he has the ability to meet the requirements."

He Siye went straight into the business.

But he didn't know much about the telescope, but he just took the crystal that met the requirements and led it over at Xu Maogong's order.

After he finished speaking, he looked at Xu Maogong.

"What's the matter with the focus, focal length, and degree crystal?"

Xu Maogong asked Li Hongru that he still remembered a little bit of content at this time, but he didn't understand what was going on.

In his understanding, the crystal must be carved into a certain shape to form the basic conditions for making treasure mirrors.

The more thorough the crystal is, the larger the arc, the stronger the hyperopic effect will be after assembly.

Xu Maogong said something and saw Li Hongru smiling and explaining to Wang Dali.

"Crystals are difficult to melt, so they can only be carved by fine carving, and they must be polished and maintained at a specific arc..."

After hearing Li Hongru's request, Wang Dali felt a headache.

Even if someone helps, he can only make up the rough. He needs to operate all the finer parts to meet the standards.

"Just tell me if you can do it," He Siye said: "If you can take on this job, and your task this year will meet the standards directly, you can go home three months in advance to hold your wife."

"My wife is very fierce. When I go back, I know I ask for my money. I don't want to see her at all." Wang Dali said, "I'm going home early and I'm tortured."

"If you can carve these two crystals as fast as possible, I can apply to the court for an additional 100 taels of silver."

After hearing a hint of possibility that Wang Dali had put in mind, Xu Maogong felt much more relieved.

Wang Dali had some implications, but everything was fine, and Xu Maogong immediately responded.

"You are a big-brained person, don't think I don't know your little thoughts. This is the Grand Governor of Bingzhou. If you do this well, you will inevitably benefit from your own good. If you don't do it well, don't blame yourself for losing your head at that time."

All the people present were human spirits, and no one knew what the hell was in Wang Dali’s belly.

After Lord He cursed, Wang Dali immediately shrank his head.

"I'm just telling the truth, haha~ I'll reward 100 taels of silver, hiccup, so much, haha..."

He smiled awkwardly, and saw that Xu Maogong did not blame him, then he whispered a few sentences with Li Hongru, and then calmed down his excitement.

"Please wait patiently, I need to discuss it carefully with this master before I can start."

Wang Dali made an invitation to Li Hongru, and Li Hongru also stepped into this not-so-large production workshop.

Many delicate tools immediately caught my eye, and Li Hongru even saw a rather primitive foot pedal angle grinder.

In Wang Dali's workshop, various finely carved props are displayed.

To the size of a copper mirror that is not much different from the mirror surface, to the size of a metal gear that is a nut.

In the current wooden design, he is very capable of using metal carving.

Li Hongru also saw a white jade-carved bell on the desktop, which looked extremely exquisite.

This manual skills are much better than his.

After Li Hongru drew the structural diagram, Wang Dali compared it for a while and barely understood the requirements before he took the tools.

His claws slowly became slender and sharp, and a little light appeared on the edge of the blade holding the file.

This is to be crafted by borrowing demonic power.

The other party had thin black hair on his hands, and the mutation was not too obvious. Li Hongru didn't know what kind of demonic power the other party had for a while.

At this time, you need to wait.

However, it is unlikely that there will be large errors in the early stages of crystal carving.

Li Hongru was bored and couldn't help but look around.

After touching a few small objects, he reached out to touch a black object, a trace of information also surged into his heart.
