Yan Ming looked at the secret door and said, "No need to guess, this secret door must have been designed by Mo Zheng." Only the Mo family can design such a trick. ”

Chengxin nodded and said, "What Master Hou said is right, it was indeed designed by Mr. Mo Zheng. ”

Yan Ming looked at this well-hidden secret door and nodded.

In my heart, I thought of the strange school of the Mo family. They have the pedagogical theories they use. Has super trick skills.

It's a pity that they have applied this trick to some small details.

What a door, a secret way. But I didn't think about using these mechanical techniques to play more powerfully.

Inside the dark passage, it was not particularly dark, and there were large pieces of night pearls on both sides.

"It's all night pearl lighting, right?"

Yan Ming asked.

"Well, it's all night pearl lighting."

It was the little soldier who followed Yan Ming in, not Cheng Xin.

"Where did you find these many night pearls?"

Yan Ming was very puzzled, Yan Yunzhong and Yan Poyu had only just come into contact with these things in the past two years, how could they be so thorough.

It was even known that in the place of manufacturing and research and development, open flames are prohibited.

There is no better light source in this era, and they have adopted night pearl lighting.

"It's a coincidence. The prince of the clouds and the son of the broken prisoner discovered that there was a mountain in the north that produced this kind of night pearl. And he led men to exterminate the bandits above. ”

The little soldier said.

Yan Ming nodded, he didn't expect the two children to be wild to such a point. He actually seized a mountain peak with soldiers and exterminated a group of bandits.

In the underground passage, there is no smell of dampness. Even Yan Ming could feel the slight movement of air in the passage.

"Did Hu Deyong also participate in the design of this underground factory?"

Yan Ming asked.

"Well, Mr. Hu came directly to direct the construction. It is not easy to say that Mr. Hu built the railway station during the day and came here to work at night. We all said that although he was young, he did look like a gentleman. That's why a lot of people call him sir. ”

The creep was visibly respectful.

In this era, a person with a skill is also the object of worship by everyone.

Yan Ming shook his head and said, "Hu Deyong has become Mr. Hu." It seems ......"

He wanted to say that it looks like I'm really old. Just thinking about this sentence may make the little soldier feel uneasy. And he took it back.

A few steps further, Yan Ming faintly heard the sound of the machine working inside.

It was a familiar voice.

In his previous life, he used to work in a machine tool factory.

Hearing the sound of familiar machining, Yan Ming had an inexplicable feeling.

He followed the sound and walked in.

Turn a small corner and see a huge space ahead.

At first glance, this space is not artificial. It should be a belly of the original earth mountain.

It's just that the current mountainside has been thought to have been transformed.

Some key places are supported by tall trees. There are also pillars made of cement on all sides.

Here, hundreds of people are working.

Except for the sound of machinery, it turned out to be quiet.

Anyone seems to be well-trained and very regular.

Seeing Yan Ming coming in from the entrance, Yan Poyu immediately came over and said, "Dad, why are you here?" ”

Yan Ming looked at the huge belly of the mountain with the bright night pearl.

Looking at the roof of the shed, it was full of night pearls. It's like the roof of the mountainside is like the sky, and those night pearls are the stars in the sky.

"You brothers, how many Night Pearls have you found?"

Yan Ming said with a smile.

Yan Poyu looked at the little soldier on the side, smiled slightly and said, "It's not much." Many of the inlays on it were collected by the robbers of the mountain. We're just going to get it. ”

"Isn't it much better than the robbers!"

Yan Ming said with a smile.

Yan Poyu lowered his head and said softly: "Dad, we are doing the right thing for heaven." ”

"I'll just say there's no difference between you. Those who occupy the mountain as kings like to say that they are doing the right thing for heaven. ”

Yan Ming said with a smile.

The father and son walked inside while looking at the various machining machines that were working.

The machine tool inside turned out to be wire-linked.

The rubber refined from petroleum was used in electrical wires, which was not much different from the wires of later generations.

"Boy, you're thinking about the principle of electric motors, why don't you study lighting electricity?"

Yan Ming asked.

"I'll wait a few days. Originally, it was also on the agenda, and it was necessary to study electric lighting. But this is not a mess, and everything can only be done for the military industry. ”

Yan Poyu said.

"A good one, everything is for the military industry."

Yan Ming nodded and said.

"Eldest prince, the barrel of the gun has been made, can you check it and see if it can be used?"

A worker walked over with grease on his hands.

"Lao Wang, your craftsmanship is indeed good. But how is this barrel stumped? ”

Yan Poyu smiled and patted Lao Wang's body, not caring about Lao Wang's oily stain at all.

Lao Wang hugged his fist towards Yan Ming, and said, "City Lord, this is a new barrel ordered by the eldest prince, but it is not that Lao Wang can't do it." You know Lao Wang's technique. ”

This old Wang Yanming knows that although he is not tall, he has an old-fashioned atmosphere. But he is one of the best mechanics under Da Lao Chen.

"Let's go, look at the barrel you said."

Yan Ming waved his hand and asked Lao Wang to lead the way in front.

Lao Wang nodded respectfully, and took Yan Ming's father and son to the edge of a table.

There were several long barrels on the table.

Seeing this barrel, Yan Ming was stunned. This barrel is not at all the same caliber as the barrel on those produced guns.

Here the barrel is long, the caliber is larger.

"What kind of gun is this?"

Yan Ming touched the barrel of the gun and looked at Yan Poyu on the side.

"Dad, that's right. Sniper rifles are mentioned in some sources. But there is no model. I designed it according to the characteristics of the sniper rifle mentioned in the book. I want to make a sniper rifle. ”

Yan Poyu said easily. But Yan Ming knew what a brain-burning thing he was behind doing this.

How difficult it is to study the sniper rifle according to the information himself, Yan Ming can't imagine it. But certainly not small.

"Dad, once this gun is successful, it can kill the commander of the army from a distance. When the time comes, the enemy army will be in chaos without a fight. ”

Yan Poyu said.

On the table, there are parts of firearms. Each part is a few sets.

It seems that this is the place where sniper rifles are studied here.

Looking at the surrounding layout and posture, Yan Poyu is obviously different R&D teams are placed in different areas.

couldn't help but glance at Yan Poyu deeply.

"Is the bullet model made?"

Yan Ming asked.

"It's made, it's two inches longer than an ordinary bullet, and the lethality should be very strong."

Yan Poyu said.

"Study it, tell me. When this crisis passes, we work on something more advanced. For example, chariots. ”

Yan Ming said.

"Chariots?" Yan Poyu knew that the chariot that his father said was definitely different from the chariot in ancient times.

(Thanks to the "Tearless Lazy" brother for the tip of 10,000.) I remember the additions requested by the lazy brother and the social worker brother. The day after tomorrow after the end of the day, after the whole day is busy, I will definitely add more. Dead Covenants. )
