"Boss, or we're going to try it out." In the workshop, Da Niu looked at the two bronze cannons in front of him with joy and asked tentatively.

"Hit, hit, hit, I'll hit you in the head." Li Chen's big slap slapped the big bull's head, and the buzzing sound.

Lijiazhuang now has more and more people, and the loss just now did not fall in a densely populated place.

"Let's go, pull the cannon, let's go to Shimen Mountain to set off the cannon." Li Chen greeted the big cow.

The big ox led a carriage, and everyone worked together to carry the cannon to the cart.

"Whoa, whoa." The big bull shouted and drove the carriage, carrying people and cannons to the camp of the Shenwu Army in Shimen Mountain.

Shimen Mountain, the camp of the Shenwu Army

"Yo, what is this? It's thick, it's big, it's shiny. Wang Li looked at the cannon with straight eyes and asked curiously.

"It's a cannon, my cannon." Da Niu hugged the barrel of the cannon into his arms and said ostentatiously.

"Come on, the big bull will shoot a shot for everyone to see." Li Chen commanded.

"Well, is that good. It's the first time I've shot in front of so many people, and I'm really excited. Da Niu's face was flushed and he was very excited.

Both guns were front-loading guns, and although the front-loading guns were troublesome to load, they fired slowly. However, relatively speaking, the structure is simple, and the manufacturing is convenient, which is very suitable for the large-scale installation of the Great Qin army.

The projectiles of the front-loading guns are controlled by slow-burning fuses.

There is a small hole in the body of the projectile, and the fuse is inserted inside. At the time of firing, the fuse was ignited by the gunpowder gas inside the chamber. After being fired, the fuse continues to burn until it burns out and ignites the gunpowder inside, causing an explosion.

The projectile of the front-loading gun is required to explode on the ground, and the length of the fuse must be controlled by the gunner, on the basis of which a cork with a built-in fuse and a scale appears, and the gunner decides how long the plug to insert into the fuse hole of the shell according to the required delay time.

"Wang Li, clear the shooting range. Keep soldiers away from the range to avoid accidental injury. Li Chen commanded.

Soon, the positions of 500 steps, 1,000 steps, and 1,500 steps were placed on two targets.

"Zi, zi."

"Boss, are you shooting accurately?" The bull held a torch and lit the fuse in the medicine room, and the lit fuse made a sound of gunpowder burning.

"Boom." I heard a loud bang in the distance, and the first target was torn apart.

"Ahh Wang Li was stunned, his mouth was wide open, and he didn't know what to say for a while.

"This ...... If this happens to people...... Coco must not be killed...... "The king has not finished speaking.

"Boom." There was another loud noise, and another target of 500 paces was directly blasted into powder.

"Boss, the power of this small cannon is not good, not even a third of the power of the cannon." Da Niu pursed his lips, looking dissatisfied.

"Be content, with it, our Great Qin's catapult is completely useless." Li Chen sighed. Good tools eliminate inferior tools, as if this is a sign of social progress.

"What catapults, what catapults...... Wang Li said, carrying a cannonball and firing like a bull.

"Well, what are you doing, did your brain fall to the ground?" Li Chen kicked Wang Li's ass and scolded.

This cannon is not a random fire, and the breech gun must be cleaned of the black powder remaining in the chamber and the chamber after each fire. If the black powder in the chamber and chamber is not cleaned and the cannon is fired, the chance of exploding the chamber will be greatly increased.

The medicine room that the big cow cleaned up, preparing for the next round of cannons, Wang Li looked at it with blank eyes, and his heart was like a cat scratching.

"Big Cow."

"Brother Niu."

"Uncle Niu, I'll call you Uncle Niu."

"If you ask me to set off a cannon, I'll set it off." Wang Li's curiosity was worshipped, and he tirelessly harassed the big cow.

"The little one lets you shoot, big nephew, don't say that uncle doesn't care about you." Da Niu is also a bastard, and he is cheap and does not take advantage of the bastard.

Wang Li was in order to make a shot, and gritted his teeth to recognize Da Niu's relative.

"Boom."

"Boom."

"Boom."

Throughout the afternoon, Xianyang City was shrouded in bursts of roar.

Fusu, Wang Li, Zhao Que, Li Chen, Da Niu, Liuzi and others were surrounding these two cannons, listening to Da Niu's analysis of this cannon.

"Boss, the firing range of the small cannon is only 1,500 steps at most, but when the solid bullet hits 1,000 steps, it will float, and the accuracy is not guaranteed. The flowering bullet has no effect, and it can hit a distance of 1,500 paces. ”

"There is no problem with a cannon hitting 5,000 steps, but in the same way, a solid bullet will float when it hits 3,000 steps, and a hollow bullet can hit 5,000 steps."

The whole body of the solid bullet is made of fine iron, the projectile of the small cannon weighs 20 catties, the projectile of the cannon weighs 60 catties, and the flowering shell is made of iron sheet wrapped in stones and broken iron.

Solid shells rely mainly on the momentum of gunpowder to smash iron pellets at the enemy, dealing damage. Flowering shells, on the other hand, explode when they hit the ground, shooting out stones and broken iron to deal damage.

In general, solid bullets are used to siege cities, while flowering bullets are used against soldiers.

Xianyang City, Afang Palace

The First Emperor had just finished reading the folds of the pile, stretched his waist, called the little eunuch waiting outside, and asked, "It's raining outside." ”

"Back to Your Majesty, it's not raining, and it's getting better." The little eunuch replied respectfully.

"And where did this thunder come from?" The First Emperor asked.

"This thunder came from the Shenwu Army of Shimen Mountain, and it is said that the Hou Ye is thundering with the Thunder Divine Sect." The little eunuch replied.

"Nonsense." The First Emperor said unhappily, obviously this was not a statement that could convince him.

"Father, Li Chen seems to have made up a thing called artillery, otherwise, let's go and have a look." Yingyue's voice came from outside.

Shimen Mountain, Shenwu Army, School Field

"Li Chen, you kid is tinkering with something weird again." Maybe a few people were too fascinated by the research, and no one found out until Ying Yue and the First Emperor got close.

"See ......" Several people were stunned for a moment, and hurriedly wanted to salute.

"Excuse me, what is Aiqing doing?" The First Emperor interrupted everyone and asked curiously.

"Da Niu, what are you doing, pull out our cannon and show it to Your Majesty." Before the First Emperor's words fell, Li Chen's big bull in the shooting range in the distance shouted.

"Boom."

"Boom."

"Boom."

There were ten more roars, solid shells, flowering shells, and ten shells that had just filled the pit at the shooting range.

Li Chen and the First Emperor observed the crater at the shooting range, and Li Chen asked, "Your Majesty, what do you think is the power of this cannon?" ”

"Of the ten craters, nine of the shallower ones were from small cannons, and one was deep from cannons."

"Due to the trouble of cannon reloading, the small cannon reloading is simpler. So this small cannon can shoot nine shells, and the cannon can only hit one. ”

"Therefore, the combined shelling method of small artillery and large artillery is called the nine shallow and one deep artillery shelling method." Li Chen pondered for a few seconds, organized his words, and said seriously.
