Gunpowder originated from alchemy, and when alchemists were refining pills, they discovered the method of ambushing fire. The so-called fire method is to use burning to remove and weaken the surname of erysipelas.

Sun Simiao, a famous doctor in the early Tang Dynasty, invented the sulfur method: two taels of sulfur and saltpeter, ground into powder, and placed in a sand pot. Dig a pit and put the jar in the pit, and fill it with earth around it, and level it with the ground. Three soaphorns that had not been eaten by insects were lit and put into jars, and the sulfur and saltpeter were burned. Until it is no longer burning, fry it with charcoal, fry it until the charcoal is eliminated by one-third, then anneal, and pour in the saltpeter and sulfur mixture before cooling, which is the fire.

Also, in the middle of the Tang Dynasty, there was a man named Qing Xuzi, who invented the method of alum: two taels of sulfur, two taels of saltpeter, and three and a half coins of aristolochia. The right is the end, mix well. Dig a pit and put the medicine in the tank and the ground. Put a piece of cooked fire, a large marble, put it in the can, and the smoke gradually rises.

Since its invention, gunpowder has gone through more than 100 years in the Tang Dynasty, the Five Dynasties and the Song Dynasty, totaling more than 300 years, and has made tremendous development. The Song, Liao, and Western Xia were all developing gunpowder weapons, but they did not achieve much.

It wasn't until Wu Ji, a master of weapons, that gunpowder took a big step forward, making the power of gunpowder unprecedentedly high, and gunpowder weapons have actual combat value.

Weapons master Wu Ji's first firearm was not a gun, but a bullet used to hunt bears.

"Fifty taels of silver, my God, that's a lot?" Yang Xiuxiu's face was full of disbelief and shock.

For the villagers of Wujiazhuang, fifty taels of silver is definitely a huge wealth, they are self-sufficient, all year round, the whole family spends only about 1,000 yuan, 5000 yuan is the cost of 50 years, close to the cost of a lifetime.

"Fifty taels of silver, which is indeed a lot. If I can get this bounty, I will not only be able to raise my body and bones, but I will also have the principal of three or twenty taels of silver, and I will be able to do business. Well, I will have a lot of things, and if I do business in the Song Dynasty, I will definitely make a lot of money. Wu Ji's eyes were also shining, dreaming of getting fifty taels of silver. In that case, it will be natural for him to improve his life and take care of his body and bones, and there will be a lot of surplus, which can be used as capital.

As for what kind of business to do, Wu Ji has not yet decided. However, one thing is certain, no matter which one he does, Wu Ji will make a lot of money, a well-off life is not a problem, and a rich life is also possible.

"But how can a bear be hunted when it is so big and so cunning? I'm familiar with modern detonation methods, but none of them are suitable for the current situation. Wu Ji thought about it, but he was helpless.

The difficulty lies in the way of detonation, and it is necessary to find a detonation method that is suitable for the situation at hand. In order to kill Ou Benqing, Wu Ji spent a lot of time and energy on weapons, and he was very familiar with the detonation method, using the fuse and remote control method, but there was no applicable way that could be done under the existing conditions.

If he didn't solve the detonation method, it would be a reward of five hundred taels of silver, and he wouldn't want to get it.

"Ji'er, uh, Zheng County's order praised me, I'm old and thick-faced, I didn't say that you taught me. I'm not embarrassed to get my light on you, but this little mutton fat is for you, so you can make up for your body and bones. Wu Qing made a grinding sound in his mouth, a little embarrassed.

What he said was all taught by Wu Ji, but out of vanity, he took this glory alone. When I came back and thought about it carefully, I always felt that the elders had taken the glory of the younger generations, which was very unpleasant, so I rushed over to compensate Wu Ji.

As he spoke, he handed over a bowl, Wu Ji took it and saw that there was a small half bowl of mutton fat, which emitted an attractive aroma, and he almost drooled.

"This mutton fat has been around for some time, and I wanted to eat it again during the New Year's holidays. But if I don't get your light in your light, if I don't ...... Ahem! When Wu Qing said that, he couldn't help but blush, pretended to cough, and didn't say any more.

Wu Ji was a little funny, he didn't take this matter to heart at all, and handed the bowl back with a smile: "Third uncle, don't take it to heart." It's a little thing, it's not worth it. Take this mutton fat back and make up for your brother's body. ”

In a small mountain village like Wujiazhuang, oil and meat are very rare. Wu Qing's right hand stretched out and retracted again, even more embarrassed: "Although Jian'er is small, his body is strong. Ji'er, your body is weak, you have to make up for it. Well, the third uncle left first, and you guys were busy. ”

He was afraid that if he stayed any longer, he might really ask for the mutton fat sent back and leave quickly. didn't wait for Wu Ji to speak, and walked away quickly.

"The third uncle is the best for us. Wu Lang, just take it, don't chill the third uncle's heart. Yang Xiuxiu also hoped that Wu Ji would mend his body bones as soon as possible.

The matter has come to this point, if you don't make it up, you have to make it up, Wu Ji held the bowl, and his heart was warm. This third uncle is really good to himself, if he has the opportunity, he has to repay it well.

Wu Ji's mending of her body and bones is her great joy, Yang Xiuxiu was very happy, helped Wu Ji into the house, lit a fire, and asked Wu Ji to bake, so she happily went to the stove to make dinner. She decided to make good use of this mutton fat and let Wu Ji make up for it beautifully.

Thinking of the oily meat, Wu Ji's taste became longer, leaning against the wall, and he couldn't stop swallowing. I really don't know how long Wu Xiucai hasn't been touched by meat before, and that saliva always can't help but flow out.

After enduring it for a while, Wu Ji couldn't bear it anymore, stood up, and came to the stove.

"Wu Lang, how did you come to be? Go bake it, don't catch a cold! As soon as Yang Xiuxiu saw Wu Ji coming in, she couldn't help but be in a hurry, hurriedly put down the mutton fat in her hand, and was about to come over to help Wu Ji.

"What are you going to do?" Wu Ji was a little curious and asked casually.

"I'll cook some dry ones, and then fry them in mutton fat, and you can replenish your body." Yang Xiuxiu came to Wu Ji's side and helped Wu Ji.

It turned out to be fried rice, and if there were eggs, fried eggs, yellow on both sides, it would be good. Wu Ji was a little lacking in heart, and with the support of Yang Xiuxiu, he was about to go back to simmer the fire, and suddenly saw that the bowl containing mutton fat was a fine porcelain bowl, and he couldn't help but be stunned, his eyes lit up, staring at the porcelain bowl.

"Wu Lang, don't be in a hurry, just work hard for a while. Once the rice is cooked, stir-fry and then eat. Yang Xiuxiu thought that Wu Ji was greedy. can't blame her, who called Wu Ji always loves to drool, and the corners of his mouth are wet, which is no different from real gluttony.

"No, no, no, this mutton fat can't be eaten! Can't eat! Wu Ji crossed his sleeves, wiped the hara on the corner of his mouth, walked over quickly, took the mutton fat bowl in his hand, and observed it carefully.

This is a good fine porcelain bowl, with the special glaze of Song porcelain, bright as jade, and it emits bursts of dazzling brilliance in the light, but it is a little flawed. Even so, if it were to appear in the modern world, it would surely drive collectors crazy.

"Ahh Can't eat it? Yang Xiuxiu was confused by Wu Ji's words, and hurriedly comforted Wu Ji and said: "Wu Lang, this mutton fat is good, it's not bad, it can be eaten!" ”

"Oh, I'm not talking about good or bad, I'm saying that this mutton fat is so useful that you can't eat it." Wu Ji said excitedly: "I thought of it!" I've got it! I finally thought of it! Xiuxiu, I've come up with a way to hunt bears! ”

"How to hunt bears?" Yang Xiuxiu was surprised, and hurriedly comforted: "Wu Lang, you have the best heart, you are afraid that the bear will enter the village and harm people and animals, so find a way to get rid of it." However, the bear is so big and cunning that it can't be dangerous. ”

"Xiuxiu, you underestimate you Wu Lang too much!" Wu Ji's chest was straight, his head was high, and he was full of confidence: "Your Wu Lang's method is particularly ingenious, even if the bear is ten times more cunning and a hundred times more cunning, it will be impossible to escape the palm of my hand." Just wait and see! Wait and see! ”

"Wu Lang, what does bear hunting have to do with sheep fat?" Yang Xiuxiu couldn't figure it out.

"Hey, hey!" Wu Ji smiled proudly and raised his eyebrows: "Without mutton fat, you can't be bait." You wait and see, go, let's go and go to the weapon! ”
