Taking advantage of the night to protect.

Everyone is ready to go.

The camp in the distance was still lit up.

At the same time, Zhang Jing issued an order: "Prepare quickly."

At this time, no one blew the whistle.

Everyone started to put cylinders into the pit.

This pit can basically accommodate cylinders, of course... it will leave some margin, and the gap in this margin can be used for irradiation.

When Zhang Jing saw that everyone was busy, he said a command and began to fill the cylinders in the soil pit with a familiarity, not without pride.

A few days ago, military academy students had already started a lot of military training after training for new recruits, and now the thing Zhang Jingyi is trying to do is the so-called "conscienceless cannon" that was famous in later generations.

The biggest problem of the Ming army was not that there were too few gunpowder patterns, but that of the people who used gunpowder and the artillery manufacturing process.

Those who use artillery, such as those gunners, basically few of them are qualified for training, and most of them are old foxes who are scattered. In wartime, they temporarily cram and know nothing about school shooting, and even have no way to control the amount of gunpowder.

The result is that various accidents occur frequently, and sometimes... the casualties caused by gunpowder are even greater than those caused to the enemy.

In fact, artillery has always been technical troops. In this era of not yet mechanized, the regularization of artillery is very important. Both are artillery, and the effects it exerts in different people's hands are worlds different.

On the other hand, the most serious problem is the problem of process manufacturing.

Because the iron smelting level in this era is not up to standard, the cast artillery often has many pores. In order to prevent the blowing of the chamber, everyone has figured out a local method. To prevent the blowing of the chamber, it is okay, my iron is not good, but I can thicken the barrel. As long as it is thickened to a sufficient level, it will ensure that the blowing will not blow up.

So many big guys appeared. The cannon running tube was extremely thick but also extremely heavy. This thing had no effect except defending the city. However, such a thick cannon barrel was actually very limited. It was a dream to kill the enemy on a large scale.

Without a conscience, the latter problem is solved.

As for the former issue, Zhang Jingyi has made up for it through continuous training.

Artillery not only has the simplicity of firing artillery, but also needs to understand basic mathematical knowledge and learn the principle of ejection.

Otherwise, even the basic military orders would be unaware of, and shooting randomly by sprinting would be of no use except wasting money.

Emperor Apocalypse was indeed very professional. When he saw these guys... he was really installing a "cannon". His instinct to survive quickly made him stay away from the cylinders one by one.

He has been professionally fired.

Of course I know that the cannon is indeed quite powerful, but... the risk is very high.

If this is blown up and the thief is not killed, he might be finished first!

After everyone silently stuffed cylinders into the pit.

Then he started to recharge gunpowder familiarly again.

Emperor Tianqi looked at it intently, and when he saw the amount of gunpowder loaded these people, he was almost suffocating.

So he didn't care about his majesty as an emperor and said with a little panic: "Slow down, slow down, why are you pretending so much? Zhang Qing wants to blow someone to death."

"This is also called too much?" Zhang Jingyi couldn't help but say disdain: "The explosive bag contains too much."

"What?" Emperor Tianqi's face turned pale and he said in surprise: "There are explosives in this bag?"

"Yes." Zhang Jingyi said calmly: "It's not just explosives, there's also iron sand inside. The iron sand is soaked in the feces and urine. Your Majesty... you won't be afraid, are you?"

This...is a bit exciting.

Emperor Aoki has never seen such a gameplay.

He couldn't help but frown and asked, "Aren't you afraid of blowing up?"

Zhang Jing smiled and said, "Aren't the iron barrel buried in the soil? It can still blow up the soil."

After loading a large amount of gunpowder, everyone started to put an isolation board in the cylinder, and then... they began to stuff gunpowder into the barrel.

Plug a gunpowder bag is a technical job. Because of the wiring, these guys have practiced it many times. The movements are very proficient and they quickly arranged the leads.

Immediately afterwards, it seemed that the gunpowder packaging was not filled tightly enough, so some people even stretched their feet in and stepped on the gunpowder packaging both feet.

In this way, live together!

“Are you ready?”

"It's ready."

"Then do it."

"yes."

In the darkness, the person who responded to Zhang Jingyi was very excited.

Among them, the man who was like an officer picked up a single-tube telescope.

This thing was bought from the Folang Jiren. It cost a lot of money, and there were only four in the military academy.

He kept observing something carefully, and finally lowered his voice and said, "From the direction of three points... This camp is big enough, just blow it up desperately. I will follow my orders..."

Hearing the order...

Emperor Tianqi couldn't help but hurriedly stayed away.

Although he was very excited inside, he didn't want to die inexplicably.

...

And at this time, in this Jiannu camp.

Among the central army's big stake, there was a man with a Ming army's armor sitting in the big stake, stepping on a wool blanket.

Although the wind is cold outside, it is as warm as spring.

The man in the Ming army was smiling and saying, "There was a sudden fire in his journey. Ningyuan City was in chaos. Yuan Chonghuan and Man Gui attacked each other and dug each other's old background. It was extremely lively. Master... I'm afraid that the collapse of Liaodong will be a foregone conclusion."

"Now the Ming Dynasty has no leader, and the generals of Liaodong are disloyal. It is a great opportunity to conquer Ningyuan in one fell swoop, attack Jinzhou, and lead troops to Shanhaiguan. When the Ming Emperor came to Liaodong, I thought it was an opportunity, so I immediately compiled a book for my master. I had long expected that the master was ambitious and would lead troops to compete with the Ming Emperor."

The master mentioned in this population is wearing a luxurious brocade dress, wearing a warm hat on his head, and an Eastern pearl is inlaid on the warm hat.

He looked at the slave in front of him, but he stood up and said in the Chinese language of a clan: "I led my troops here this time, but it's a pity that the little emperor of the Ming Dynasty died first. Otherwise, he would have captured the little emperor and he could take Beijing directly. However... the people of Liaodong are now volatile, but it is also a good time to launch a large-scale attack. If you make contributions to your news, you will definitely be rewarded at that time. After this battle, I will carry your name and let you become a real bannerman. By then, you and I will be the real master slave."

The man was overjoyed and knelt down quickly and said excitedly: "It is a blessing for me to serve my master. Master, please be careful. In Ningyuan City, my subordinates have already prepared. When Master, you take down Yizhou Guard first, you can go straight in. At that time, I ask my subordinates to open the city gate and my master can take down Ningyuan in one fell swoop."

The master nodded, smiled, and said, "Okay, you don't have to be excited. I know your loyalty... You should go back first, don't let Yuan Chonghuan and Man Gui in Ningyuan City doubt it."

"Yes." The man stood up with gratitude, wiped his tears and nose, nodded and bowed, "Master, take care of yourself."

Then, he quickly stepped out of the tent.

He left.

Then a Jiannu Niu Lu came in. This man was young, but his face was full of beard.

He turned around and glared at the Han general with disdain. When the man walked away, he sneered: "This kind of person... the master also said that he was loyal and righteous. If he was loyal and righteous, how could he serve us?"

The Jiannu man, wearing a warm hat and fair face, smiled and said, "This is what the Han people are like. If you want to control him, you will have to say some beautiful words. It's like we fishing and hunting. When we let dogs chase bears, we need to give him a piece of meat first and touch its head. Why, Obai...what are you going to do?"

The young man named Oboi seemed to remember something important and hurriedly said, "The spy said that there seemed to be someone moving in the southeast. At first I thought it was a scout, but I noticed it, it didn't seem like... it seemed that there were a lot of people."

The man wearing a warm hat laughed: "Since the Ming army defeated a small group of military horses in the capital, they have no idea that the sky and the earth have become rich. It seems... they have become familiar with night battles recently, but it's a pity... I'm just waiting for them to attack at night tonight! In terms of their military tactics, it's called waiting for their leisure! When they really attack, they can capture all their carefully selected elite soldiers in one fell swoop."

"I heard that when the Emperor of Ming Dynasty came here this time, he also brought an elite soldier stationed in the Jinzhou Guard. We two thousand eight banner elites, how could we lose to hundreds of Han soldiers? Tonight... I'll give them a result. Make arrangements, pretend not to notice their traces, hide ambushers in the camp, and then... I'll capture them all."

"yes."

Oboi bowed and left with pride.

...

At this time, the Ming military academy students had filled all the explosive packs.

Zhang Jingyi and Emperor Tianqi were already very familiar with each other and were both lying on the ground, acting like a boy should protect himself well.

Immediately afterwards, a long whistle blew under this quiet night sky.

So, one by one, the fire snatched the leads of the explosive pack first, and then... someone lit the leads of the gunpowder in the iron barrel.

boom……

A muffled sound made the earth shock.

Zhang Jing suddenly felt that this vibration made his internal organs uncomfortable.

At the same time, the iron barrel buried in the pit shook violently and emitted a flame, and then... the first explosive pack that was half a millstone... passed a perfect half arc in the sky, and the lead of the gunpowder pack was still emitting a dazzling flame in the air.

Then, a continuous roar came.

Dozens of gunpowder packs fly in the night sky at the same time.

In this moment.

Fire trees and silver flowers, and the dark night sky is filled with stars!
