Hearing this, several soldiers glanced at each other, and they all saw a thick anger in each other's eyes.

Ye Fusang suddenly got up and said in a lazy tone: "I have a way to retreat from the enemy." ”

Listening to Ye Fusang's fluttering words, several ministers glanced at each other, and the dark-faced woman suddenly stepped forward, "Under Ziming, I don't know what the county lord's method of retreating from the enemy is?" ”

Ye Fusang raised his eyebrows and glanced at her, "Artillery fire, with artillery fire, we can destroy the Northern Hell." Ye Fusang's voice was categorical, sonorous, and confident, and for a while, several ministers were stunned, but not by what she said, but by her momentum.

"Hmph, artillery fire, it's all outside, the county lord won't be invisible, right?" The dark-skinned woman glared at Ye Fusang with extreme disdain, she knew that this gentleman woman would never be able to say anything good.

Hearing this, Ye Fusang glanced at them, and his face began to recover a little serious, "Artillery uses gunpowder to exert powerful destructive power, and that gunpowder is made of sulfur, saltpeter and charcoal, presumably all the generals here know that the greater the weight of gunpowder, the greater the power of the artillery, and the bearing capacity of the cannon barrel is a problem." There is too much gunpowder, and the barrel of the cannon can't withstand the explosive force of the gunpowder, and it explodes in place before it is fired...... I'm sure you've encountered it when you're making artillery, right? These naturally can't be concealed from Ye Fusang, she has already done her homework by the way when she came, this ancient science and technology is not developed, she just needs to think about it.

The tent was immersed like death, and all the soldiers were in a cold sweat!

How did this woman find out? This is Jinzhou's military secret!

From the time of invention to the production of artillery, to the production of artillery, they did try to increase the power of the cannon and increase the dose of gunpowder, but the bronze barrel could not withstand the powerful explosion force at all, not to mention that no shells were issued, and even the experimenters were killed a lot, these are the secrets of Jinzhou, and outsiders have no way of knowing.

At this time, the eyes of all the soldiers were immediately focused on Ye Fusang, and they also had some ideas, although that budding thought had not yet gathered into a clear answer to the surface!

"Jinzhou has a large amount of saltpeter and sulfur, you immediately assign people to buy all the bronze and iron in the city, come back, I will be useful."

Looking at Ye Fusang's confident and calm appearance, the soldiers began to hesitate, and after a while, Wang Lan nodded, "Can the county lord of Zhaoyang really retreat from the Northern Underworld army?" ”

"If not, I, Ye Fusang, will be at your disposal!" Ye Fusang's words hit everyone's hearts heavily.

At this time, Zi Ming stepped forward, "General Wang, let's believe in the county lord once, and use the dead horse as a live horse doctor." ”

Hearing this, the corners of Ye Fusang's mouth twitched, this person, should you be so direct.

When Wang Lan heard this, he thought for a while, "Okay, listen to the county lord of Zhaoyang." ”

Ye Fusang nodded at Wang Lan, "As long as we collect these things, we will definitely be able to win, and if we have a strong enough barrel, we can increase the amount of gunpowder and greatly increase the power and range of the artillery." If you don't believe me, I can do an experiment for you. Her incomparably confident attitude makes her instantly radiant and dazzling!

Although they were still skeptical about Ye Fusang's intentions, at least there had been a lot of improvements, Ye Fusang smiled slightly, and decided to make them happy, "General Murong is on his way here, I think it will arrive soon." ”

"What? General Murong is here? ”

"General Murong is here, and we have hope......"

Looking at their excited faces, Ye Fusang nodded slightly, unexpectedly, this Murong Yan's prestige in the army was quite high.

――――――――――――――――――――――――――

In a corner of Jinzhou, in the center of an empty sandy area, there were two people, Murong Yan and Ye Fusang, and around them, there was a circle of generals in armor.

There was a small cannon between Murong Yan and Ye Fusang, which was the tool that Ye Fusang was about to demonstrate.

This artillery was proposed and developed by Ye Fusang, and it can be said that it was the first batch of artillery in this era, not to mention the simple structure, and its function can be regarded as an improved trebuchet!

The principle of the trebuchet does not need to be explained, the trebuchet is aimed at throwing boulders and injuring the enemy, and its operation requires forty to two hundred people, and the artillery of this period uses the explosive force of gunpowder to shoot the cannonball, so it is the size of the explosive force that determines the power of the artillery, because it directly determines the volume, weight and range of the cannonball.

In this early stage, Ye Fusang saw through the artillery at a glance, because one of her former roommates was the dealer in this area, and after a long time, she knew a little bit about it.

The soldiers brought wires and powder powder for artillery, as well as crude shells.

Ye Fusang turned to the direction of the soldiers, "My experiment is mainly to prove the prospect of artillery transformation, I think you all think that this artillery is useless, but in fact, it is not, if you master the methods and tricks, this artillery is a weapon with great lethality, now I will do the experiment." ”

Ye Fusang divided the gunpowder sent into three parts, two of which were equal parts, and the third part was twice as large as the other two.

"The first thing I've proven to you is that the more gunpowder, the longer the range." Then she turned to Murong Yan, and saw Murong Yan looking at her blankly, and the burning eyes made Ye Fusang roll his eyes a little uncomfortably, "Can you send me an artilleryman?" ”

"Hmm." Murong Yan nodded and called a soldier, the soldier skillfully put the fuse and stuffed the gunpowder, and when the cannonball was released, he was stopped by Ye Fusang, and still turned to everyone, "Because we are experimenting, the purpose is to prove the range of the artillery, in order to make it more convenient to observe the results, and not to injure everyone by mistake, this cannonball is uneasy, let's install the stone." ”

"Stones?" People look at each other, I look at you, you look at me.

A young general stepped forward, "County Lord, I have a suitable stone here, similar in weight and size to a cannonball, you wait, I'll come when I go." ”

Soon, the young soldier brought the stone, which did resemble a cannonball.

The soldier who was doing the experiment put the stone into the barrel of the cannon, ignited the fuse, and with a loud bang, the stone was shot out. Another soldier immediately rushed over and measured, "One foot and three feet!" He shouted in return, marked the place where the stone landed with white powder, and then carried the stone back.

Ye Fusang nodded, pointing to the largest amount of gunpowder, "The second one uses this gunpowder." ”

The soldier did as he was told, and with a louder bang, the stone was shot out, and the measured soldier's voice came from afar, "Two feet and two feet." ”

The generals whispered that they had known this result for a long time, that the more gunpowder, the longer the range.

Ye Fusang pointed to the last unused gunpowder, "Now this gunpowder." ”

The onlookers talked loudly, not to mention Murong Yan, even the soldier who was doing the experiment was stunned, this gunpowder was equal to the amount of the first gunpowder, and the shell was the same shell, why did it fire twice? But he didn't dare to disobey the order, so he still filled the lead gunpowder according to his words, loaded the stone cannonballs into it, and when he was about to ignite the fuse, Ye Fusang came to stop it.

She squatted down, there was a stone base under this small artillery, and the gun was fixed horizontally on the base, Ye Fusang glanced at the target that was about to shoot, adjusted the gun to an angle of 40 degrees with the ground, and then got up. "Now light the fuse."

The soldier glanced at Ye Fusang curiously, and secretly suspected that this cannon was placed diagonally, and it was the first time he had heard of it.

And the soldiers also talked a lot, although it was not sarcastic, but there were also some doubts.

The fuse ignited, and with a loud bang, the stone bullet shot out in a parabola, and shot far before hitting the ground. The measuring soldier was stunned for a moment, ran over, and the measurement results came out, and even he doubted, "Three feet and one foot." ”

At this time, the whole crowd was boiling, they didn't know, it turned out that just by tilting the barrel of the cannon to increase the firing range, why didn't they find out before?

Wang Lan looked at Ye Fusang with incredible eyes, "The county lord is really young and promising, before, I was ignorant, but how did the county lord know that the artillery could shoot farther when it was tilted?" ”

Ye Fusang's evil smile froze for a moment, this ...... This one...... How do you explain this? With the principle of mechanics?

Ye Fusang: "I guessed ......"

Wang Lan: "......"

Seeing that Ye Fusang didn't say much, Wang Lan was no longer reluctant, at this time, no one doubted Ye Fusang's ability, and the morale of the soldiers also increased, as if victory was just around the corner.

The fatigue of the past few days has already overdrawn Ye Fusang's physical strength, and Zi Ming took a step forward worriedly, "That...... County Lord, I'm watching here, you better go and rest. She didn't expect that the world-famous county lord of Zhaoyang still had such a ability, it was really a rumor that could not be believed.

"Okay." Ye Fusang smiled at her, these people are all people with real temperament, very cute.

As soon as he walked a few steps, Ye Fusang felt a sharp pain coming, and his brows furrowed tightly, isn't it, at this time, what kind of crow is it.

took out the pill that Sakura Jixi gave before leaving, Ye Fusang was a little entangled, Sakura Jixi said that this pill has the ingredients of flattering medicine, and she can't eat more, then, if she eats less, it shouldn't be so sad to poison her hair, if the poison is poisoned, there is no man here to solve it.

Adhering to the principle that eating less will be fine, Ye Fusang raised his head and threw a pill into his mouth, and sure enough, the pain was reduced, but it was still a little painful, the sweat was still rising, and his hands and feet were weak and sore.

Although Murong Yan was supervising the production of artillery, his eyes were staring at Ye Fusang's figure, seeing Ye Fusang's footsteps stumbling a few times, his body went straight down, Murong Yan was startled, and stepped forward with an arrow, steadily catching Ye Fusang's falling body.

The moment he caught Ye Fusang's body, Murong Yan was a little surprised, her body was so soft, and there was a faint fragrance, as a general, he didn't hold a woman, those soldiers were injured, and he also rescued them, but their bodies were very tough, but hers was very different.
