Datang: Combining the dual combat power of Lu Bu and Xiang Yu at the beginning

Everyone dug out the mud membrane of the barrel and smashed the mud mold with a hammer.

Li Zhiyun then found a slender spear and hung out all the sediment on the surface of the copper cannon barrel and in the chamber and dumped it.

In this way, a copper cannon barrel with a somewhat rough appearance appeared in front of everyone.

Everyone gathered around, admiring the inexplicable happiness of the barrel.

Who knows, Wu Shu directly poured a basin of cold water:

"I don't know what you are happy about, how to use such a rough thing?" Zheng

Wenxiu also discovered this problem, and immediately found a file and a grinding stone, and polished the surface of the barrel with the pure green hand speed practiced over the years, polishing the rough edges and trachoma.

Li Zhiyun threw an appreciative look at Zheng Wenxiu, this water master general is still a little keen.

"Zheng Wenxiu, don't just grind the outside, use the boring knife to deal with the inside of the barrel!" Zheng

Wenxiu immediately started working again, but Cheng Yanjin asked a little puzzled

: "Emperor, if the outside is grinding, why should the inside be sharpened?" Without

waiting for Li Zhiyun to answer, Luo Shixin returned first:

I said that you are really stupid, so that the inside of the barrel is as straight as possible, so that the shell can better eject from the barrel!"

When did Lao Luo become fond of learning?!

People love to specialize so much, they must also work harder!"

"Lao Luo, come here, I want to draw the drawings of the gun mount." "

But there is no paper here, so I am aggrieved to draw a picture on your back!"

Li Zhiyun said to Luo Shixin.

Such an important drawing, the emperor chose to draw on himself, which shows that he trusts himself!

A moment later, a drawing of the overall shape of the artillery appeared on Luo Shixin's back.

Everyone stared at this "human flesh drawing" carefully.

I have to say that Li Zhiyun's drawing level is really high! Everyone can understand at a glance!

Li Zhiyun

looked at everyone's admiring expression and secretly had fun.

In my

previous life, I had taken art class, okay?

I also won the championship of the elementary school group of the art competition in one fell swoop!

"Everyone will make a gun carriage according to this drawing!" "

After making the gun carriage, we will improve it on the basis of the bamboo barrel grenade, and the gunpowder composition inside will not change, just make a round shell

!" A trace of cruelty suddenly flashed in Li Zhiyun's eyes:

"In addition to adding gunpowder, you can also add gunpowder to the shell... Shards of glass, make shotshots!"

The image of attacking enemy troops with such shotguns instantly appeared in my mind.

A shotgun with infinite power smashed on the deck of the Goguryeo warship.

Suddenly, Mars splashed and burned the warship, and the exploding glass shards would stab all the surrounding soldiers to death

! That picture, it's terrifying to think about

! This kind of shell can definitely beat Goguryeo to death!

For example, what to visually inspect the barrel ah, to see if there are obvious defects, hit the barrel with a hammer ah, see if it has cracks, what blocks the fire door on the barrel, pour water into the inside of the barrel to see if there is water seeping out ....

The most important thing is that the specifications of the barrel and shell must be "unified caliber" to avoid trouble in the future!

After the explanation, Li Zhiyun ordered all the soldiers to start building artillery in an all-round way, and he took some glass, and he prepared to develop a pair of scopes to put on the artillery to increase the hit rate.

Wu Shuhua always followed behind Li Zhiyun, without any intention of leaving.

The clever Luo Shixin saw Li Zhiyun's helplessness, and immediately pointed to

the barrel and said: "Emperor, if there is a crack in this barrel, will it explode the chamber?" Wu

Shu glanced at Luo Shixin and said angrily:

"Say nonsense, the barrel will not explode!" "

Yes, Brother Yun, hehe..."

At present, we don't have a single shell, everyone has to hurry, it is not possible to release the cannon

!" "Wu Shu: ???

"Forget it, I'll go back, leave some time for Brother Yun to make shells!"

Wu Shu left, and pulled Changsun Wuxian by the way.

Changsun Wuxian did not mention Li Shimin from beginning to end, but she was basically sure that Li Shimin would not die yet.

Ten days later.

The first gun was finally made according to Li Zhiyun's strict requirements, and everyone pushed the gun to the side of Luoyang Lake and loaded it onto the hull.

Li Zhiyun stroked the fort with conviction, and said, "Soldiers, where do you want it to hit?" "Where do you want it to

hit?"

"The emperor is saying, where is this artillery gun?"

Li Zhiyun nodded noncommittally:

"Yes, where to fight!"

Suddenly, all the sailors and soldiers were interested, looking around for targets.

"Hey, everyone, let's see, is it General Luo Shixinluo under that

big tree?" "What is he doing

?" "Is it counting ants under the tree?" Cheng

Yanjin pointed the fort at the tree in the distance with an evil smile:

"Emperor, let's shell Lao Luo!" Suddenly

, the black barrel was aimed at the big tree.

In the distance, Luo Shixin was enjoying the shade under the tree.

What he didn't know was.

The pot fell from the sky!
