Zhu Yunxi agreed and said: "In the previous period, Zhang Ergong, the Minister of the Ministry of Industry, also found his son and said that the supervisor had come up with some good things. He originally wanted to send them to the Southern Expedition Army to let General Chang go first.

It is for trial use. Now it can be used in the southwest in advance, and it will also be convenient for people from the Ministry of Industry to verify whether there are any improvements in the new firearms."

There was a trace of curiosity on Zhu Biao's face.

The Ministry of Industry has always come up with several new and good things from time to time in the past two years. Although there are no such things as steam engines and trains now, they are still good things that are practical and beneficial to the country and the people.

Now hearing what Zhu Yunxi said, Zhu Biao was immediately curious. The Ministry of Industry had come up with something again. It seemed that it was a firearm specially used in the terrain of southwest and southern Xinjiang.

Zhu Yunxi was smiling.

correct.

What the Ministry of Industry has now come up with are two more portable artillery pieces.

Different from the new artillery that was developed by the Ministry of Industry in pursuit of high power before the Northern Expedition, the current artillery is lighter and more convenient.

When the project was approved for the new artillery acquired by the North, the requirements given by the imperial court were very simple.

Great power and large caliber.

The weight and transportation convenience of the artillery are completely ignored.

Anyway, those artillery pieces are either placed on the city walls, or they are used for bombardment by large corps in the plains and hills, or they are relatively reduced versions used on new warships.

The result satisfied everyone.

The new artillery is powerful enough.

Many people even think that even if the city wall of Yingtian City is bombarded by new artillery, it may not be more than ten shots that can blast the wall open.

After the Northern Expedition, the Ministry of Industry only revised some of the data on the new artillery, and then devoted all its efforts to the lightweight artillery that was developed later.

Zhu Biao asked expectantly: "What kind of new firearm is it?"

Zhu Yunxi explained: "The power is much smaller than that of the past, but it is better than the light weight. Even the heaviest of the two recently developed artillery pieces only requires a group of war horses to drag it.

.

If there are no horses, a team of ten can carry the cannon, its gunpowder, and shells to the required location."

"How powerful is it?" Zhu Biao's eyes began to shine.

Zhu Yunxi thought for a while and finally found a reference: "The gate tower outside the Wenhua Palace can be destroyed with only three cannonballs."

Zhu Biao looked at the gate tower at the front of the Wenhua Palace and couldn't help but nodded: "This is powerful enough, and it is enough to be used in the southwest mountains."

More than enough.

In the past, if the imperial court sent a large army into the mountains to search for and suppress the rebellious chieftains, the most they could do was use some firecrackers.

Three cannons can knock down the palace gate tower. If it were used to the southwest, one cannon would kill at least a dozen people.

Zhu Yunxi changed his words and said: "It's just that if you want to go deep into the mountains in the southwest, this cannon is still a bit heavy and will slow down the soldiers. On the contrary, it is another cannon, which is completely different from all the current artillery. Most of all, it is

It’s convenient and not too powerful.”

Zhu Biao had already stood up, sat on a chair nearby, and took a sip of water from his teacup: "Tell me quickly."

Zhu Yunxi smiled.

The gun he was talking about was actually a mortar.

It was not the mature mortar that would be seen in later generations, but it was not a native cannon either.

The gun barrel is easy to say. As long as it is made slightly thicker, it can still avoid exploding the barrel. What limits the faster development of mortars is that it is impossible to make too obvious a leap in the research and development of artillery shells.

He explained: "It is a cannon barrel that can be lifted and carried by two soldiers. When used, it is connected to the bracket. The cannonball is also the latest one, but it is not ideal yet, so the power is artificially controlled.

.Probably, it can cause damage within three steps."

Mortar shells with a killing range of four to five meters are already the largest range that the Ministry of Industry can control.

Mainly due to the limitations of the stability of the excitation device and the shell itself.

Zhu Yunxi saw that his father was a little confused, so he continued to explain: "Although this cannon is not very powerful, it is the most lightweight. There are many mountains in the southwest, and the ups and downs are the largest.

If ordinary artillery were used, no matter how high the muzzle was, it would be impossible to attack the camp on the top of the mountain from the foot of the mountain.

But this new cannon is different. It can be inserted almost directly into the ground. The shells first rush into the sky and then slide down to the target area. This solves the problem of ordinary artillery that cannot have the muzzle too high.

Although the power is small, in the mountains of the southwest, even the troops of the chieftain forces can only shrink into a small area, so the small power is not a problem."

Zhu Yunxi thought of the appearance of those toast cottages in the southwest.

Once the imperial army approaches the border, those chieftains can only huddle in the stronghold. As long as the cannonballs fall and land in the right place, there will definitely be a crowd.

Zhu Biao listened to this, but there was no picture in his mind.

He couldn't help but look at Zhu Yunxi.

"Let's go take a look now?"
