Shiraishi answered, and walked to the artillery with a few guards, and he was in charge of the test firing.

According to the method of using the cannon formulated by Lu Yuan, he first fixed the angle with the door, and then took out a wooden stick wrapped in a white cloth and cleaned it in the barrel.

The cannon was loaded forward, and Shiraishi stuffed the powder bag wrapped in oiled paper into the barrel and stabbed it into the bottom with a wooden pole, and then stuffed the heavy iron ball into the barrel, and then stabbed the bottom with the same wooden rod.

The next step is very important, the drill pipe is pierced through the gunpowder pack through the fire gate, and then the lead is inserted into the gunpowder pack, so that the pre-launch preparations are completed.

Before Baishi lit the fire, Lu Yuan reminded: "After lighting the fire, quickly retreat, pay attention to protect your own safety." ”

"My subordinates understand."

Seeing Shiraishi lighting the fuse with a torch, the eyes of the onlookers widened.

The officials of the Engineer Academy had seen the Divine Fire Thunder, so they all showed expectant eyes, especially Qi Guangzi, who had spent more than a year developing this iron pipe, and wanted to know what the use of this iron pipe could be.

The officials of the Privy Council, except for Yu Xun, were calm and ignorant of what was coming.

Qin Youyu, Su Qingzhe, and Zhang Dezhong frowned and pondered, Sun Shaoqing had a smile on his face, very interested in this strange thing, Ji Yan's expression was solemn, revealing a little melancholy about Lu Yuan's behavior of being keen on this kind of thing.

Just when everyone was in different moods, there was a boom, and a violent explosion erupted in the iron pipe-

Ji Yan stumbled, if it weren't for Ma Kong's quick hand to support him, he almost fell to the ground.

When I looked up, I saw a puff of gray-white smoke coming out of the front of the barrel, and the front of the gun was dusty, but I didn't know what was happening.

Ji Yan looked around and found that the military attache of the Privy Council was as dazed as himself, and someone was whispering in the Engineer Academy.

"Your Highness, what was that voice just now?" Sun Shaoqing asked, her pretty face was pale, and she was obviously frightened.

"The sound came from the barrel." Qin Youyu was quite calm.

Lu Yuan smiled slightly, but did not explain, he really wanted to observe more of everyone's reactions at this time.

Shi Chongxin pointed in the direction of the target and said in a deep voice, "I just noticed that there was dust rising over there. ”

As soon as his voice fell, a figure hurriedly ran towards the target in the distance, it was Yu Xun. The others seemed to understand something and ran over one after another.

Lu Yuan followed slowly. However, when he saw the target, his face changed slightly, and the armor that was the target was intact.

"Where's the iron ball?" Someone looked around, and they all guessed that the iron ball had been launched here.

"What the hell is going on?" Ji Yan rushed over panting, his expression a little dazed.

Geng Qing looked around and wondered, "Will the iron ball still be in the iron pipe?" ”

Qin Youyu shouted to Jin Yuanwu, who was standing next to the artillery and observing, "General Jin, let's see if there are any iron balls in the iron pipe!" ”

"Nope!" Jin Yuanwu replied from afar.

At this moment, a voice full of excitement sounded: "The iron ball is here!" ”

Everyone turned their heads to look and saw Yu Xun coming from a distance, holding a dark iron ball in his hand.

He walked from behind the target, which means that the iron ball was hit behind the target in an instant.

Shi Chongxin was surprised and delighted, such a long shooting distance was simply a water war artifact, and the other naval officers were also extremely excited, although the army generals also had happy faces, but they were quite calm.

"Your Majesty, can this thing be made in large quantities?" Yu Xun's eyes flashed.

"Yes." Lu Yuan smiled.

"It's a pity that the accuracy is insufficient." Geng Qing commented.

"I can adjust the accuracy slowly!" Qi Guangzi said loudly, his joy at the moment was beyond words.

Such a heavy iron ball, when it flew out, it was almost invisible, you can imagine how powerful it will be, he looked at Li Mu defiantly, and found that he was looking at the cannon in a daze.

"I'll help too." Lu Yun'er said with some frustration that her cloud crossbow was compared to this iron pipe, which made her a little disappointed.

"Your Highness, why can this thing produce such a powerful force and throw such a heavy iron ball?" Qin Youyu asked the doubts in his heart.

This is also what the others want to know, and they all look at Lu Yuan.

"Actually, it's very simple, using the flame explosion inside the iron pipe." Lu Yuan replied.

"Is a gunpowder explosion so powerful?" Ji Yan said in a daze.

"Ordinary gunpowder naturally does not have this power, but the iron pipe uses improved gunpowder, thanks to the officials in the gunpowder concept." Lu Yuan looked at the Taoist priests.

Sun Ji hurriedly came out: "What did the king say, we haven't developed a better formula these days, it's really ashamed." ”

"No, I've seen all your efforts these days, gunpowder research is very dangerous, and some of you have been injured as a result, I know that. Gunpowder research is a process of accumulation, and I believe that as long as you continue to work hard, you will definitely be able to achieve results! ”

"Thank you, Your Excellency." The Taoist priests were very moved.

Ji Yan and Zhang Dezhong glanced at each other, and finally knew what their own monarch was doing when they were looking for these Taoist priests, and they couldn't help but feel a little ashamed when they thought he was studying the elixir.

Next, the test launch proceeded to the second round.

This time, everyone was staring at the muzzle of the cannon, and as the roar rang out, some sharp-eyed people could barely see the shadow of the cannon as it came out.

This time, Lu Yuan personally adjusted the angle, and the artillery successfully hit the target, and the armor was completely deformed. Where it was hit, not only did the front and rear armor stick together, but a palm-sized hole was also ejaculated.

"How? Do you think this thing can hold back the cavalry charge? Lu Yuan looked at the officials of the Privy Council.

"Absolutely!" Jin Yuanwu said excitedly.

"I'm afraid this thing will come over, and within a hundred steps, no one in the world will be able to dodge." Ma Kongming smiled bitterly, and this sentence was said by him, which was very convincing.

Gang Quan frowned: "Your Majesty, this thing is too complicated to operate, it seems that it takes several people to operate, and the cavalry charge speed is too fast, it is estimated that when the cavalry from a thousand meters away rushes over, it will only have time to fire twice." ”

His implication was that it wasn't practical in the wild.

"And this thing is too bulky, and I'm afraid I'm going to get stuck in a mud pit that is not easy to walk." Geng Qing added that for some reason, he was a little afraid of this thing and didn't want to use it.

"But you can use it when defending the city." Kim Won-woo retorted.

"In my opinion, it can also be used in field battles, depending on the skills that the Lord will use." Qin Youyu said.

"The cavalry is too fast, and the last general still thinks that this thing alone can't stop the cavalry charge!" Gangquan insisted on his opinion.

"Didn't the mother say it all? It depends on the techniques that the Lord will use. Hearing Qin Youyu's speech, Geng Qing immediately jumped back.

"Of course, it is not possible to rely on artillery alone, but what if artillery and cavalry are combined, and a round of iron balls is fired first, and then our cavalry charges?" Qin Youyu explained.

"Niangniang is right, in this way, our cavalry will have a great advantage!" Geng Qing agreed.

Shi Chongxin hesitated for a moment and said: "I think this kind of artillery is okay to defend the city, and if you fight in the field, you can't stop the iron cavalry of the Khitans, so it's probably difficult to make them chaotic." If artillery falls into the hands of the enemy, it may be copied by them and used to attack our cities. ”

He was the only person present who had seen the Khitan cavalry, and he still had lingering fears about the horror of the Khitan iron cavalry.

Lu Yuan was shocked, Shi Chongxin reminded him very right, the Khitans are good at field warfare, not good at attacking cities, so they can't put artillery into their hands.

"Do the Khitans have two more hands or two more feet? With the help of artillery, if the cavalry still can't beat the other side, it can only mean that the commander is derelict in his duties! Yu Xun said lightly.

Shi Chongxin opened his mouth, but finally did not refute.

In his opinion, although the Wu army's combat strength is good, it is not comparable to the Liao State and the Zhou State, but at the moment, these words are useless, and they will only provoke the dissatisfaction of other generals with him.

At this time, Su Qingzhe spoke: "Your Majesty, this weapon needs to be ignited to ignite, will it not be able to use it in rainy weather?" ”

"Yes, it can be problematic when using it in the rain." Lu Yuan's jaw head,

Geng Qing was suddenly a little disappointed: "That's too unstable." ”

"I have understood the principle of artillery, and I will design other stable ignition methods as soon as possible." Lu Yun'er whispered.

Qi Guangzi glared at her: "I can make a baffle on the cannon to block the rain, isn't that enough?" ”

"It's better to improve the ignition method according to what the envoy said." Lu Yuan hurriedly spoke,

Historically, artillery has been continuously improved and developed in ignition methods, and he doesn't want Qi Guangzi to deviate from the direction of his research.

Generally speaking, the artillery test firing was very successful, and with the help of artillery, it will greatly enhance the Wu army's defensive capability and water warfare capability.

As for the field battle, Shi Chongxin reminded that in addition to using it when attacking the city, when fighting with the Liao, try not to drag it to the field to fight, so as not to be captured by them.

But this is just the beginning, and in the future, as long as the money continues to be invested, the artillery can continue to grow.

Lu Yuan knew that his ability was limited, so he could only grasp the general direction, and the task of industrial development still had to be handed over to these professional craftsmen to promote.
