Du Wenhao smiled bitterly, took a front-loading flintlock pistol, poured gunpowder into the barrel, wrapped the iron projectile in greased deerskin, stuffed it into the barrel, poked it into the pestle with a strip and tightened it, and then fixed the gun on the launcher, tied the rope, and came to the back of the bunker, this time he let the others squat, and he lay on the bunker to observe.

As soon as I pulled the string, I heard a bang.

Hearing this voice, Du Wenhao was happy again, and hurriedly ran over to take a look, the humanoid target in front of the muzzle was still clean, and the projectile fell two or three steps away from the muzzle. - It is clear that the charge is too small and the power is not enough.

Du Wenhao only knew the firing principle of the flintlock pistol, but he didn't know the amount of charge, for fear of exploding, so the charge was relatively small.

After Du Wenhao recharged the charge, he stuffed the bullet again and fired another shot, this time the charge was too much, so he heard a bang, and the barrel exploded again.

Burst two guns in a row, it seems, the barrel material is not up to standard. "What material is this gun made of?" ”

The blacksmith said, "It's iron." ”

"Although iron is hard enough, it is too brittle and easy to burst, so it will be replaced with brass or bronze later."

"Yes!" The blacksmith hurriedly agreed.

Du Wenhao took the last gun, and because of the material used to explode the barrel as a reference, this time the charge was between the two.

Du Wenhao found that the power of gunpowder was too small to form an explosive flying power, so he didn't bother to hide behind the cover, so he stood a few steps away from the gun and pulled the rope. Wang Runxue and several craftsmen stood behind him and looked at him with great novelty.

Du Wenhao looked back and smiled, and as soon as he pulled the rope, he heard a loud bang, and a wisp of black smoke came out of the muzzle, which quickly dissipated.

Fifty paces away, on the chest of the humanoid target, there was a small black dot!

"It worked!" Du Wenhao shouted happily and ran over to check the humanoid target, only to see that the thumb-sized iron bullet was shallowly attached to the humanoid target. Although it didn't penetrate deeply, it was enough to excite him.

Wang Runxue and the others looked at each other, this was the first time they had seen a firearm that used gunpowder as a power to launch projectiles, but the power was far less than that of a bow and crossbow, at this distance, the bow and arrow could easily penetrate this humanoid target. And this strange firearm can only superficially smash the skin of the humanoid target. They didn't know what Du Wenhao was doing when he tried something as complex as a bow and crossbow.

Du Wenhao was also dissatisfied with the power of the gun, and it was estimated that the gunpowder was not enough, so he increased the dosage a little more, and conducted another test firing, and as a result, it exploded again!

To prevent the chamber from exploding, one is to replace the pig iron with a toughness material, and the other is to use a metal shell, which can increase the air tightness and reduce the possibility of exploding.

Du Wenhao asked for another pen and paper, drew a metal bullet casing, and he didn't know how to do the thunder mercury in the fuse part, so he still used a flint to ignite the fire, which would lose part of the air tightness. But it can't be helped.

Although the test could not be regarded as a success, the main purpose had been achieved, that is, after this test, Li Hong and his team had learned the principle of firing firearms from the real thing, and laid the foundation for further improving the manufacture of firearms and the manufacture of cannons.

Du Wenhao asked the craftsman to separate the exploded barrel, and found that the inner wall of the barrel had not been polished, so he called the craftsman over, pointed to the inner wall and said: "The inner wall of the barrel must be polished and smooth, the smoother the projectile resistance, the farther the projectile will be shot." In addition, we are using iron projectiles now, which is too heavy, so we need to use lighter metal and replace them with lead bullets in the future. ”

Li Hong hurriedly agreed. Du Wenhao also designed a detachable bayonet in the lower part of the muzzle. They were asked to change the design of the charge on their own, and the purpose of the experiment was that the lead bullet fired could penetrate a wooden humanoid target fifty paces away, and the continuous fire would not blow up the chamber.

On the way back, Wang Runxue said: "Xianggong, is this thing you invented to surprise horses?" ”

Du Wenhao was stunned: "Surprised? ”

"Yes, I heard this sound so loud, dozens of times louder than the war drums, if the enemy's war horses on the battlefield heard such a huge sound continuously, they would definitely be shocked and chaotic."

Du Wenhao smiled bitterly: "This is a shooting weapon, which fires metal projectiles, the same as a bow and crossbow." However, what you said about scaring the war horse can be regarded as an additional role of it. It also has a certain effect on dealing with the impact of war horses. ”

"However, I saw just now that the projectile that shot is far less powerful than the bow and crossbow."

"The test has not been successful yet, and the power of the future will definitely be much more powerful than the sharpest bow and crossbow. Take your time and you'll know later. ”

"Oh." Wang Runxue nodded, "By the way, how are you preparing for the military exercise?" ”

"It's almost, the beginning of autumn officially begins."

"Can I participate?"

"Of course you want to participate. You also have to help me check whether their drills meet the requirements of the art of war, and propose further rectification plans. ”

"Let me give my opinion, I don't know!"

"You are familiar with military books, how can you not know it? You need to help me see what they did wrong, and I can fix it. ”

"Then ......, I'll try." Wang Runxue nodded.

A few days later, the beginning of autumn finally arrived.

Before this, Du Wenhao didn't go to the various barracks to wander around, and let them practice by themselves. Early in the morning, Du Wenhao was dressed in military uniform, riding a jujube red horse, carrying a rotten silver spear on one side, and hanging a bow and arrow on the other, Wang Runxue also wore a battle robe and rode a white dragon horse, looking heroic.

Du Wenhao took Wang Runxue and the escort team to Sanya first.

Under the flagpole on the side of the Sanya gate, there is also a general, riding a black war horse like carbon, wearing an armored battle robe, and hanging on the side of the saddle is a simple knife. is smiling at Du Wenhao. It was Zhao Lan, the eldest princess of the Qin Kingdom.

Du Wenhao glanced at Wang Runxue next to him inexplicably. Wang Runxue shook the reins and rode over first: "Sister Zhao Lan! What are you doing here? ”

Zhao Lan is more than ten years older than Wang Runxue, when she got married, Wang Runxue was still young, and later her husband was executed for collaborating with the enemy, Zhao Lan became a little widow and returned to the palace, Wang Runxue is the daughter of the prime minister, often looking for Zhao Lan to play, and the two became close friends in the boudoir.

Zhao Lan glanced at Du Wenhao and said, "I heard from the queen mother that General Du is going to conduct a military exercise today, I like to be lively, I told the queen mother, I came to take a look." What about you? What's the matter, became the wife of the general and the head of the guard? ”

"I can be a guard with this three-legged cat kung fu, and I'm here to see the excitement. Just like you! ”

Du Wenhao looked at the second daughter and said, "The time is almost coming, I want to go in and raise the general, you can wait for me outside." ”

The two girls said in unison: "No! We're going too! ”

"Oh well! Walk! Du Wenhao was too lazy to be verbose, "But you have to be behind the screen to raise the account, and you can't come out." ”

"Okay!"

There is a little military field in the backyard of Sanya, and a big tent is set up in the middle, although this is in the capital, there is no need to build a big tent here, but Du Wenhao is particular about the atmosphere, and deliberately let his subordinates set up a standard marching army tent.

At this moment, more than a dozen commanders above the army level were already waiting here.

Du Wenhao stepped into the middle military tent, sat in the middle, and glanced at the military lawyer next to him: "What time is it?" ”

"It's almost time."

"Are you all there?"

The military lawyer smiled a little embarrassedly: "There are still two left." ”

Du Wenhao's face sank: "Worse than two?" What did you do? ”

"I don't know, I should wait and arrive."

"Wait? I am a dignified prince of the town, all three yas are checked, one of the eight governors, who else in the army has such a big shelf for me to wait for him? - Drum and raise! General Ben wants to be a big deal! ”

Outside the big account, the war drums suddenly shook the sky and the earth.

Once the drum is beating, those who don't arrive are late.

After beating the drums, no one came. Du Wenhao sneered, opened the roster on the table, and began to roll out names one by one.

After the list was counted, sure enough, the two generals did not arrive, he closed the roster, stood up and said, "Everyone, follow me to the military exercise ground outside the city!" ”

All the generals hugged their fists and agreed, turned around and got on their horses, and followed Du Wenhao out of the city.

As soon as he arrived at the city gate, he heard the sound of horses' hooves behind him, and soon came to Du Wenhao's side, and said in a big voice: "General, I'm sorry, it's too late for the end." ”

Du Wenhao grabbed the horse's head, didn't turn around, and said coldly: "Do you know what the crime should be for before the point arrives?" ”

"This ......, hehe, please forgive the general, I drank with Lord Cao last night, and I drank two more glasses, so I came late. Don't dare next time! ”

"Drink with Lord Cao?"

"Yes, yesterday was the birthday of Lord Cao. So drank a few more glasses. Hehe, in the past, the last general was never late, this time please let the general spare me. ”

Du Wenhao slowly turned around: "Originally, it is okay to spare you, now it is not a march to fight, and there is no need to be too strict......

The big voice grinned: "Isn't it, it's still the general who is reasonable, tonight, please let the last general be the east, and set up a banquet to make amends to the general!" How is it? ”

Du Wenhao said coldly: "I haven't finished my words yet, don't be happy first." - Originally, it was okay to go around you, but I raised the account for the first time today, and I won't punish you for being late, so everyone will follow suit in the future, how can I still serve the public? - Military lawyer, what should I do if the point has not arrived? ”

"Thirty rods in peacetime, slash in wartime!"

"Good!" Du Wenhao stared at the loud voice of the general and said: "You should be glad that you are not in the Huanqing Military Strategy Division, otherwise, the head on your neck will not be protected!" Come! Thirty rods! ”

This time, Du Wenhao has a military law team that is specifically responsible for enforcing military law. In unison, they agreed, and five or six military soldiers came up and dragged the general off the horse.

The general was so frightened that he begged for mercy, and was pushed to the ground by the military lawyers, and he picked up his staff and was about to be beaten.

The loud-voiced general was anxious, and said sharply: "General, please look at the face of Lord Cao, bypass me for a while." ”

Du Wenhaoqi said: "Look at the face of Lord Cao? What is your relationship with Lord Cao? ”

"Lord Cao is my brother-in-law!"
