My Backyard is the Tang Dynasty

The trade fair that Li Yin mentioned was simply a food tasting event. After Li Yin explained it, several people understood it.

"The people's livelihood is the issue that you parents and officials should pay attention to first. You guys will be responsible for the next exhibition. You can't let me intervene in everything, otherwise, how can you still establish your prestige in front of the people?" Li Yin faced several people. said the man.

Several people looked at each other and said, "Then let's try, Your Highness!"

Li Yin nodded. The reason why he delegated power in this way is to train a few people, otherwise it is not good to be too dependent. After that, there will be more things to be planted in Yizhou and even Chengdu.

After explaining this matter, Li Min rode back to the palace, and Jin Daqian greeted him on the way, panting, and said: "Your Highness, the person from Taoyuan said that the gun made by Guo Xianyuan had made a breakthrough. , do you want to go and have a look?"

"Really?" Li Yin was overjoyed, and lashed the red boy's **** with a whip, and the beast ran towards the south gate with a neigh and a hoof.

"Hey, Your Highness, wait for me!" Jin Daqian tugged at the rein for a long time before turning the horse's head around. This ordinary horse just couldn't compare with a **** BMW. Thinking of this, Jin Daqian hurriedly returned to the palace and shouted A nursing home chased after Li Yin all the way.

Li Yin rode his horse all the way and arrived at Taoyuan in more than an hour. The guards in front of the fortress saw that it was Li Yin and saluted one after another. The weapons made by the workshop, not to mention the horizontal knife, are also crossbows and compound bows in their hands.

There are about a hundred people equipped with advanced guards. Even if thousands of people come, they can hold on for a while.

Li Yin put down his horse and walked directly to Research Research Institute. Now the research institute has been built, the small village has been transformed into a living area, and the craftsmen have moved to work in the research institute, and various equipment and books have been placed in corresponding areas of the research institute.

Li Yin went straight to the laboratory of Guo Xianyuan and Tong Yu when he went to the research institute. At present, one of the two specializes in artillery and the other specializes in firearms, but what Li Yin did not expect was that Guo Xianyuan was so accomplished in firearms. It will be researched soon. Or copied out.

"Bang!" As soon as Li Yin stepped into Guo Xianyuan's exclusive testing ground, he heard a gunshot. Tong Yu was aiming at a target not far away with a long pole weapon. This was specially made by Li Yin. In the experimental field, it is specially used for experiments.

After firing a shot, Guo Xianyuan, who was standing on the side, was about to run over to see what the target was like, but when he caught a glimpse of Li Yin, he kicked Tong Yu to remind him. Both of them came towards Li Yin.

"I heard that Guo Xianyuan developed a musket?" Li Yin walked over and said directly.

Guo Xianyuan showed a proud face, took the musket from Tong Yu and put it in front of Li Yin.

Li Yan took over the musket. These are indeed not the model guns he brought from country m, because the barrel, **** and parts are brand new.

"Thanks to the machine tools sent by His Highness, without those things, these suitable parts cannot be produced in a short time." Guo Xianyuan explained.

Tong Nian nodded in agreement, "Yes. Your Highness, and the mold you mentioned. Now my cannon has also made great progress. It may not be long before I can carry out design tests."

These machine tools are specially used to produce some small parts, and these small parts are sometimes the most important.

Li Yan looked at the gun made by Guo Xianyuan for a while. It was found that it was a little different from the flintlock he had brought over, as there was no flint on it. Instead, it has a needle-like firing mechanism.

"Guo Xianyuan, what kind of flintlock gun are you imitating?" Li Yin was a little strange, but he vaguely felt that he seemed to have seen a firearm similar to this gun when he checked the information, but he didn't think about it for a while. stand up.

Before Guo Xianyuan spoke, Tong Yu immediately explained: "Your Highness, originally this gun was imitated from the breech-loading flintlock gun, but later Xianyuan discovered another strange gunpowder when he was refining alchemy."

"Alchemy?" Li Yin squinted at Guo Xianyuan with his eyes, this guy is unforgettable in his profession.

A thin layer of sweat suddenly appeared on Guo Xianyuan's forehead, thinking that Tong Yu really has a big mouth, and he can't tell him everything in the future, so he turned his eyes and said: "Your Highness, I only come here occasionally Nothing happened, so I will refine the pill for a while."

Li Yan didn't mean to blame him. After all, alchemy is a legal and reasonable thing in this era, but he said: "Don't let others eat the alchemy, otherwise it's up to me to punish you."

"Yes, yes!" Guo Xianyuan kept nodding his head as if he had been pardoned.

Li Yin then asked, "What kind of gunpowder?"

Guo Xianyuan took out a cylindrical object as long as a little finger from his pocket, Li Yin looked it over carefully, it looked a bit like a firecracker.

"Your Highness, please stay away. This one doesn't use steel balls, but it's powerful." Guo Xianyuan put the "firecracker" in his hand and reminded.

Li Yan stood back as he said, but Tong Yu didn't care. He and Guo Xianyuan had done several experiments and got used to it.

Seeing Li Yin standing aside, Guo Xianyuan grabbed the object and threw it to the ground, only to hear a "pop", a layer of flames appeared on the ground, and then thick smoke drifted away, and a strong smell of gunpowder permeated the air. in the air.

Li Yan thought to himself, isn't this the enhanced version of throwing cannons? It's just that the ingredients of this cannon are silver salt, nitric acid, and sand. Guo Xianyuan may be able to mess up this nitric acid, but he thinks it's impossible for this silver salt. Li Yin thought of something and said: "Did you use it? The white crystals from the chemistry lab?"

"Your Highness, how do you know?" Guo Xianyuan was shocked.

Li Yin understood a little bit, "Did you mix sulfur and carbon with this white crystal?"

Guo Xianyuan looked as if he had seen a ghost, and nodded as if lost his soul, "Yes, Your Highness."

"No wonder!" Li Yin muttered in a low voice. When these three things were mixed together, it was one of the earliest fire caps born in the 18th century in the West, that is, acupuncture firing medicine. It was made by accident.

The white crystals are actually potassium chloride. After Li Yin set up the chemistry laboratory, he also bought some chemicals, and this potassium chloride is one of them.

The firing powder mixed with these three things can burn as long as it is violently hit, thus igniting the delayed gunpowder, which is a sign of the rise of breech-loading guns. Unexpectedly, this Guo Xianyuan directly completed the cross-generational development, and this also required Credit to Li Yin for the variety of cross-generational offerings.

Guo Xianyuan suddenly felt nervous about the thief being exposed in broad daylight, and said, "Your Highness, please forgive me!"

Li Yan patted him on the shoulder with a smile, "Why are you guilty? Not only are you innocent, but you have also made great contributions."

"This..." Guo Xianyuan was at a loss.

Li Yan praised the principle and function of the fire cap to the two, and the two suddenly realized that the fire cap was so important to firearms.

"However, this flash cap must be stored separately in another place. Remember to handle it with care, otherwise there will be serious problems." Li Yin warned.

Knowing that the cap is so easy to catch fire and explode, the two of them secretly wiped off a cold sweat. Just now they were throwing the bullet without marbles next to a pile of gunpowder to play. Thinking about losing their lives, the two of them were afraid after a while. .

After talking about the fire cap, Li Yin took a bullet from Guo Xianyuan's hand. Of course, this bullet is not the modern advanced copper shell bullet, but is wrapped in paper, similar to firecrackers. The bullet is filled with marbles. Used to kill.

Li Yin loaded the bullet from the breech on a whim, and then aimed at a target fifty meters away. There was a "bang" gunshot, and Li Yin leaned back slightly. The power of the bullet was still satisfactory.

Putting down the gun, he and the two walked towards the target. After searching for a long time, they found a bullet hole at the bottom of the target. It was no different from dragging the target. It seemed that training was needed.

Then, in order to test the effective range of the percussion gun, Li Yin asked Guo Xianyuan to shoot at a wall more than 100 meters away. In Li Yin's opinion, the speed of reloading the percussion gun has been accelerated, and the power of the bullets has also increased significantly. , the effective range should exceed the effective range of the flintlock, but deliberately still can't match the compound bow.

But this is also normal. After all, the range of the compound bow of modern technology has been greatly enhanced. It can be said that it has more than doubled the range of the current bow and arrow, but with the same effective range, the firing gun can shoot through plate armor. It can't be done, which is why bows and crossbows will be gradually eliminated, and there is still a gap in penetration.

Holding a percussion gun, Guo Xianyuan made designs at distances of 50 meters, 70 meters, 100 meters, 120 meters, 150 meters and 200 meters. The power and accuracy of firing the gun within a distance of ten meters is not bad. The steel ball penetrated deeply into the mud wall. Beyond this distance, not only the accuracy, but also the power will be greatly reduced.

For comparison, Li Yin called a guard who used a compound bow. Unexpectedly, even with a flat shot, the effective range of this compound bow reached 150 meters, and with a 45-degree throw, it could reach about 400 meters.

Comparing the two, Guo Xianyuan couldn't help but feel a little disappointed. He didn't expect that what he had spent so long to make was not as good as a compound bow.

Li Yin was already very satisfied with the result. Compared with the effective range of the flintlock, he saw Guo Xianyuan's expression and said with a smile: "Don't be discouraged, he is an old archer with great strength. To be able to shoot so far, the percussion gun you developed is much more powerful than this."

Li Yin is telling the truth. The archer just now used a 200-pound compound bow, which is extremely powerful, but not everyone has this kind of arm strength, and the power of bows and arrows lies in long-distance projectiles. Not on the percussion gun.
