Zhu Yuanzhang was immersed in everyone's congratulations, and did not understand the meaning of Li Wei's smile, of course, he would ignore it if he saw it.

After firing three shots, the Shenji cannon in the field was temporarily quiet, two people were busy charging, and the other three began to adjust the angle under the command and shoot at the earth ring target two miles away.

Due to the distance, the target was also larger, measuring 30 meters.

A moment later, three more cannon shots rang out, and the cannonballs whistled into the distance, and only after these three shots did several craftsmen completely stop moving.

Everyone on the stage also fell silent, and some of the pre-arranged fast horses rushed to the position of the earth ring target, picked up the shell, and reported the hit.

After Li Wei learned from Lu Ti's mouth, he reported to Zhu Yuanzhang: "Your Majesty, this artillery test firing was all hit by three guns at one mile, two at two miles, and one shot missed the target. ”

This test launch was tested in advance, and the results are already very good.

"Yes, the fight is quite accurate." Zhu Yuanzhang nodded slightly, and then urged: "Isn't there still two kinds of artillery, let's pull them up too." ”

"Yes, Your Majesty, wait a minute."

Li Wei agreed to come down and asked Lu Ti to arrange it as soon as possible.

After a while, several craftsmen led their horses and pulled the Shenwei cannon up.

The thick body of the Shenwei cannon is more than three meters long, and compared with the Shenji cannon next to it, the identity of the eldest brother is undoubtedly revealed.

Under the operation of the craftsmen, Shenwei aimed at a large flag on a distant barren mountain, blasted out, and then the cannonball disappeared.

The speed of the shells of the Shenji Cannon is slightly slower, and it can barely be seen with the naked eye, but the Shenwei Cannon is different, the cannon is ejected extremely fast, and it is difficult to distinguish with the naked eye.

When everyone squinted their eyes and struggled to look into the distance, Li Wei quietly took out the binoculars, looked around the banner, and finally saw a big tree that was cut off by the waist, and then breathed a sigh of relief with satisfaction.

Fortunately, although the banner was missed, it was not far away.

"Your Majesty, this Shenwei cannon has a range of more than five miles, and its power is huge, if it is continuously bombarded at close range, the ordinary city wall will not last a day and will be destroyed."

Li Wei opened his mouth to introduce.

"You mean this cannon can knock down the walls?"

Zhu Yuanzhang suddenly looked at him after hearing this, and asked in shock.

Zhu Biao, Feng Sheng and other generals also looked over in shock.

In ancient times, the most difficult thing to fight was siege warfare, even if ten times the force of the siege wanted to fight down, it was not so easy, once encountered the fierce resistance of the defenders, often a year and a half can not be attacked.

But if Li Wei's cannon can really collapse the city wall, then the siege will be much simpler!

"Yes, yes, but it takes a little more time and shells."

Li Wei affirmed that because this Shenwei cannon is made of steel, it is more powerful than the most famous Hongyi cannon in the Ming and Qing dynasties, and this powerful artillery is the most suitable for siege.

When everyone heard this, they were shocked and whispered!

Although Li Wei said that it would take a whole day to bombard, compared to the siege warfare that took a year and a half to fight a dozen battles, this time was almost negligible.

Now they are attacking the city, mainly relying on human lives to fill in, of course, there are also return cannons, mortar cannons and the like, but the effect is not very large.

If his divine cannon really has such power, it will be a sharp weapon for attacking the city!

Zhu Yuanzhang's face also became solemn, he was silent for a moment, and said in a deep voice: "You have to keep this kind of artillery strictly secret!" ”

Li Wei smiled and nodded, "Your Majesty rest assured." ”

For this, he is not worried, casting cannons is not a simple matter, from the blast furnace of steelmaking to molding, the double diameter size of the barrel, and granulated black powder, these are all technical barriers, if you want to understand them all, even if you go to the Ordnance Bureau to learn it, you will not be able to learn it in a while.

Technology is like this, if you can't keep up with one step, the gap will get farther and farther, and it will be difficult to learn.

Zhu Yuanzhang saw his confident appearance, only then did he breathe a sigh of relief, his eyes turned, and he suddenly saw the telescope in his hand, and asked curiously, "What are you?" ”

Li Wei followed his gaze and looked at the telescope in his hand and said with a smile: "Oh, this is a telescope, through which you can see things in the distance." ”

"Show us." Zhu Yuanzhang stretched out his hand and said.

Li Wei did not hesitate, handed him the telescope, and explained how to use it at the same time.

It is a simple telescope, made of two copper tubes sleeved together, and the length can be adjusted to see the distant scene.

Zhu Yuanzhang followed the method he said, put the telescope in front of his eyes, and looked in the direction of the barren mountains in the distance, only to see some outline trees with the naked eye, but through this telescope, he could clearly see the branches and leaves, and felt as if he was close in front of him.

Such a miraculous thing made his face look surprised again.

He was half a horseman, and immediately realized the importance of this thing for marching and fighting.

"This thing is also to be kept secret!"

"Your Majesty rest assured."

Li Wei solemnly agreed, but he didn't care in his heart, although these things were good, they were just emergency supplies that he took out to hand over the task to Zhu Yuanzhang, and he would naturally make better ones in the future, but whether to hand them over or not would have to be considered.

"Father, can you let me try?"

Zhu Biao saw that his father was holding a telescope to look here and there, and he was also a little curious, and as soon as he put it down, he hurriedly said.

Of course, Zhu Yuanzhang will not be stingy with his good children, so he handed him the telescope.

Zhu Biao took it and tried it like he had just done, and was suddenly amazed.

Feng Sheng, a veteran, was also very curious, but he was thin-skinned and didn't ask His Majesty for it, and the other generals were the same.

After a while, Zhu Biao had enough of playing, and when he saw that these generals next to him were looking at him, he suddenly understood, glanced at Zhu Yuanzhang, and saw that he nodded slightly, so he handed the telescope to these generals next to him and tried them one by one.

"It's amazing that I can see things in the distance so clearly."

"I can see the bugs on the leaves over there!"

“……”

A group of generals shouted and scrambled.

"Let's do more with this telescope, and we want to reward the soldiers who went on the expedition. These guns also have to be produced in full force. ”

Zhu Yuanzhang turned around and said to Li Wei.

"Yes, Your Majesty."

After thinking about it, Zhu Yuanzhang said again: "Let's continue to supervise the Shenji Battalion and train them in the tactics of these artillery." ”

Li Wei nodded yes.

After the generals scrambled for a while, Zhu Yuanzhang took the binoculars back and put them directly into his sleeve.

Li Wei just didn't see it, this was originally what he was going to give, and he didn't think about asking for it back.
