In the Xiande Hall of the East Palace, Xin Liangchou is waiting for Li Shimin to review it.

"This Yuan Shan, as soon as he opened his mouth, asked me for ten artillery, and Xin Jian Zheng has a few artillery pieces in the General Weapons Supervisor." Li Shimin said.

"There are a total of 25 artillery pieces under the ordnance supervision, 10 small-caliber sample guns, 15 medium-caliber guns, and 500 rounds of shells each." Xin Liangchou said.

"He asked for ten cannons, so he gave them them." Li Shimin said.

Li Shimin thought that no one should know more about the use of firearms than Yuan Shan, and he just used Du Fuwei's matter to improve the combat effectiveness of his Northern Ya Army.

Li Shimin is also very concerned about Du Fuwei's affairs, and he is not willing to let his loyal ministers be wronged.

Even if Yuan Shan didn't say it, he would ask about Du Fuwei, this kind of thing to slap the emperor in the face, especially at this time, how could he miss it.

Three days later, all the 6,000 soldiers of the Beiya School were gathered here, and today's Yuan Shan was very different from the past, today he was wearing a camouflage uniform, not to mention how dazzling it was at the front of the school field.

His colorful costume was so strange that the ghost hunter rode behind him, and no one was not afraid to look at it.

"Now all the lieutenants are out of the ranks." Yu Chi Baolin shouted.

A total of 6,000 soldiers came out of thirty captains, and together with three captains, they formed a small squadron.

"Okay, from now on, you will give priority to learning and mastering the use of artillery, and let me popularize the knowledge of these cannons to you first......" Yuan Shan began to explain to everyone.

Then Zhang San drove the carriage over and shouted, "Young master, I'm here."

"Paulin, you go and ask him to hand out the operating manual from the car to the soldiers." Yuan Shan said.

"Teacher, most of the soldiers are illiterate." Yu Chi Baolin explained.

"Of course I've thought about it, so these are comic books, don't ink and send them quickly, maybe it's not enough, then read it evenly, and let them memorize it." Yuan Shandao.

"Okay, teacher." Yu Chi Baolin agreed to come down.

"Report, artillery reloaded." The soldier shouted.

"Aim, fire!" Wonshan immediately shouted.

"Boom, boom, boom......"

The school yard was full of smoke and dust, and all the soldiers watching behind were stunned by the loud sound and the ground that had been blasted open by projectiles in the distance.

The horses in the school yard were frightened and began to neigh, as did the war horses ridden by the Ghost Hunter.

Yuan Shan was also a little excited about this improved cannonball, after all, this was the second time he had done such a thing as playing with a cannon.

"That's tough, one more round." Yuan Shan exclaimed excitedly.

"Yuan Shilang, don't wait for me in a hurry." Suddenly, I heard Xin Liangchou's voice coming.

"Xin Zhengjian, why are you here?" Wonsun asked.

"Your Majesty asked me to verify the performance of the artillery and cooperate with Yuan Shilang in training." Xin Liangchou said.

"Well, you're just here to watch." Yuan Shandao.

"One more round, master the time, and give me one by one this time." Yuan Shan said.

"Boom, boom, boom......"

"It's really loud, this time the two guns are fired at the same time, look at the length of the arquebus on the artillery, and remember the ignition time." Yuan Shandao.

"Boom, boom, boom......"

"Three more killsak." Yuan Shandao.

"Yuan Shilang, twenty shells have been used up here, and the armory supervisor does not have much inventory of shells." Xin Liangchou said distressedly.

These shells are all treasures in the ordnance superintendent, and they are only used when they are tested, where is it like Yuan Shan, and if it continues like this, thirty rounds a day will not last for ten days.

You must know that it is not easy for the ordnance supervisor to produce these shells, the process is complicated, and the output is very small, because the stability of this improved gunpowder is too poor, and if there are too many piles, there are potential safety hazards, and there will be explosions before.

"Xin Jianzheng, the cannonballs are really not much." Yuan Shandao.

"Not much, really." Xin Liangchou replied.

"Got it, keep firing." Yuan Shan said.

"This ......" Xin Liangchou was speechless.

Thirty shells were fired after three rounds of gunfire, and it is not certain how well these soldiers fought, and the targets they hit were chaotic.

Xin Liangchou couldn't stand it anymore, this was not as accurate as the craftsmen who tried the guns, he understood that this was purely for listening.

Xin Liangchou guessed right, Yuan Shan just wanted to listen to the sound, he was an ordinary person, and he really didn't know much about artillery, his purpose was that these soldiers would listen to the movement first.

"Yuan Shilang, this directly consumes half of the ammunition, and the weapons supervision stock is not much, so it may not be able to support training tomorrow." Xin Liangchou persuaded him.

"Xin Jianzheng, what you said is right, but it is not okay if there is no projectile, the use of artillery in war is like this, what is fought is consumption, if you can't even take out the projectile that is currently being trained, then don't carry out the project of this artillery, artillery without projectiles is a pile of rotten iron." Yuan Shan said.

"Yuan Shilang, we also want to make more projectiles, but the stability of the improved gunpowder is too poor, and it is not easy to make them in large quantities." Xin Liangchou said helplessly.

Yuan Shan was a little curious about how the gunpowder formula he shared could be unstable, could it be that the craftsman of the weapons prison had made a mistake in the formula.

"The gunpowder is unstable, are you making a mistake?" Yuan Shan said directly.

"Yuan Shilang, is this gunpowder originally fine?" Xin Liangchou also said skeptically.

"Of course no problem, I'm going to cheat you, and I don't want you to do anything." Yuan Shandao.

"Uh...... yes. Xin Liangchou thought about it.

"Well, I'll go to the Ordnance Prison tomorrow and see how you make this gunpowder." Yuan Shandao.

"Then there is Lao Yuan's waiter." Xin Liangchou immediately said humbly.

"Keep shooting, each of you lieutenants will fire a few times, follow the operation guide, and do a good job of each one." Yuan Shandao.

"Teacher, can you let us play with it too, not to practice the use of artillery." I heard Wei Dayou say on the side.

"Huh? You're all cavalry running here to join in the fun. Yuan Shan said casually.

"Teacher, we are the instructor team of the Northern Ya Army, if we don't know how to use artillery, it won't be a shame, this is a shame for the teacher." Wei Da has a way.

"Your sister will talk to me, but what you said is not unreasonable, let all your people be in place and train with these soldiers." Yuan Shandao.

"Thank you, teacher." Wei Dayou said immediately.

The 6,000 people in the Beiya School Yard were almost listening to the sound this day, and with the participation of the ghost hunter riders, the test firing was not ten cannons coming together, but one by one.

Not to mention that after careful study by these people, the accuracy of this artillery has really improved a lot.

There were not enough shells for these people to hoa, so after running out of shells, the soldiers were asked to touch the artillery in batches and study it with the operation manual.

There are no shells, how will tomorrow's training be carried out, so he saw Xin Liangchou on the side and said: "Xin Jianzheng, let's go, let's go to the ordnance prison."

"Okay......" Xin Liangchou had already waited for Yuan Shan to speak.

I hope readers can support more, ask for rewards, ask for collections, recommend tickets, and give a few monthly passes!
