Chapter 9 Ascending to the Disciples

As soon as Wu Ji's words fell, he raised his feet and was about to leave. Yang Xiuxiu hurriedly stopped: "Wu Lang, the meal is ready, it's not too late to eat first and then cook." ”

"Ready?" Wu Ji couldn't wait to make the weapon right away at this time, how could he be in the mood to eat.

"You don't need to fry in oil, it's fine." Yang Xiuxiu said as she busily served the meal. A bowl of rice was put in a bowl, brought to the table, and then helped Wu Ji to sit down.

"What about you?" Wu Ji looked at the rice and did not move the chopsticks.

"I have! I have! Yang Xiuxiu was afraid that Wu Ji would be suspicious, so she pretended to be serious.

"Don't I know you yet? Go get the bowl. Wu Ji's face sank, and he was very domineering: "When didn't you give me something to eat, and you ate it thin?" You're the time to grow up, that's not good! ”

"Wu Lang, I really ......" Yang Xiuxiu had to say more.

"Say no more!" Wu Ji's face sank, and his tone became a little stern.

Yang Xiuxiu was stunned, and then went into the house and took a bowl out. Wu Ji put the bowl in front of him, poured most of the dry rice into her bowl, and pushed it in front of Yang Xiuxiu.

Yang Xiuxiu looked at the dry rice in the bowl, tears rolled around, and she almost wanted to cry. In her mind, Wu Ji is a talent and a supreme existence, Wu Ji gave her food, although it was a concern, which moved her. However, she was very scared and couldn't bear it.

"Eat quickly, help me make weapons after eating, I can't do it alone, and I want you to help me." Wu Ji changed the topic and urged softly.

"Hmm!" Yang Xiuxiu nodded slightly, holding the bowl, crying silently while picking up rice.

Wu Ji sighed secretly and began to pick up rice. After a few strokes, I put the bowl down, went to the utility room, took out the saltpeter and sulfur, and prepared to dispense gunpowder.

"Finally came in handy!" Wu Ji looked at the saltpeter and sulfur in his hand, and he was very comfortable.

When he first saw these two things, Wu Ji thought of preparing gunpowder. However, I don't know where it will be used. Later, I heard about the bear, and I couldn't find a clever way to detonate it. Now that the problem is solved, it's time to put it to good use.

"How is this going to happen?" Yang Xiuxiu put away the dishes and chopsticks, rushed to Wu Ji's side, and asked curiously.

"First of all, we must boil nitrate to remove the impurities in this saltpeter. This saltpeter has survived, but there is no way, and there are a lot of sundries. It's easy to do, a basin of hot water, a piece of linen will do. Wu Ji looked at the saltpeter and saw that there were some impurities in it.

Since the invention of gunpowder, our ancestors have been trying to find ways to increase its power, and one of the most important ways is to boil nitrate. In the early days of gunpowder, people such as Sun Simiao and Qing Xuzi used fire to burn, which was actually a way to remove impurities.

By the Song Dynasty, it was a golden age of gunpowder, and firearms in human history appeared. Although the Song Dynasty was incompetent and did not establish a strong martial arts, it had amazing achievements in the research and development of weapons, and artillery and rockets appeared during this period.

The technology of boiling nitrate was not very mature during this period. In the Song Dynasty, there were many places to boil nitrate, and Sichuan Jiangyou was the most important nitrate producing area. Here, there are still relics of the Song Dynasty boiling nitrate preserved.

Wu Ji played the role of a cripple duangong, sitting on the ground and making the law, moving his mouth but not his hands, as soon as he said, Yang Xiuxiu hurriedly went to get a clay pot, filled it with clean water, and put it on the hot water by the fire.

As soon as the water was heated, Yang Xiuxiu went to get another ragged shirt, which was made of burlap, with patches stacked one by one, and a slight estimate showed that there were no less than thirty or twenty of them. Under Wu Ji's guidance, fold it several times to make a filter cloth.

Finally, find another container, and after filtering, you need something to hold it. These things are very shabby and barely usable, Wu Ji is a little sad to see it, this family is too poor, and only a girl with a very good heart like Yang Xiuxiu is willing to marry her. If it is placed in modern society, even if it is a doctor, so poor, no girl is willing to stay by a waste.

As long as you have studied junior high school chemistry, you can do it, and it is not difficult at all. When the water was hot, Wu Ji poured saltpeter into it and stirred it with a small wooden stick.

Look at it, as soon as Wu Ji said okay, Yang Xiuxiu picked up the crockpot, and slowly poured it on the filter cloth according to Wu Ji's instructions. It doesn't seem to have many impurities, but as soon as it is filtered, it will appear, and there are so many.

Filtering, it's done very quickly. Next, it is boiling, that is, the process of thickening, which only needs to be heated by the fire. The only unpleasant thing is that the smell is a little unpleasant, but fortunately, it can be endured.

Taking advantage of this, Wu Ji was ready to grind the charcoal finely and get ready. Sulfur does not need to be treated, only the charcoal needs to be prepared, and the saltpeter can be prepared with gunpowder.

Yang Xiuxiu rushed to work again, and under the guidance of Wu Ji, he grinded charcoal. This is a physical work, although Yang Xiuxiu's body bones are much stronger than Wu Ji's, and it took a few fine sweats to complete it.

Look at the nitrate in the jar, you can't boil it anymore, you have to let it dry on its own, otherwise, if you simmer by the fire again, it will ignite, and it will be in vain.

Yang Xiuxiu poured out the saltpeter, and according to Wu Ji's instructions, spread out the saltpeter, a thin layer, and occupied a piece of land for the boss. In doing so, the contact area is increased, and the water evaporates easily and dries quickly.

Yang Xiuxiu's face was stained with a lot of charcoal, her pretty face was black, and she was about to catch up with the bottom of the pot, so she washed two large basins of water before she washed her face white and tender.

Wu Ji was very excited, and he didn't feel the slightest sleep, so Yang Xiuxiu had to accompany him. Yang Xiuxiu was an idle person, so she took the needle money and began to do needlework. She is ingenious, and her one-handed needlework is very popular in the village, and the people of Wujiazhuang ask her to do needlework.

She is also happy to help with this kind of favor, she can exchange some food, she can also get favors, and when she needs help, the people of Wujiazhuang are willing to help.

The moon is dark and the wind is high, the autumn wind is cold, and the people of Wujiazhuang huddle in the house to keep warm.

A black shadow appeared silently, tiptoed, came to the outside of Wu Ji's house, a pair of eyes on the hole in the wall, peeking into the room, and his eyes glowed strangely from time to time.

Wu Ji was bored in every way, so he could only enjoy the young girl under the lamp to pass the time. Yang Xiuxiu has just washed her face, her pretty face is white and clean, as pink as a tender lotus, her eyes are bright, she is very spiritual, and her body is petite, which has a unique attractive charm.

Buddha wants a golden body, people want clothes, if you get a beautiful set of clothes for Yang Xiuxiu, she will definitely be a charming beauty. Not to mention, she is so kind and hardworking, it is even more difficult to find in the world.

"This crossing, it seems to be earned! is not only a beautiful wife for nothing, but also such a hard-working and kind person. At this moment, Wu Ji was particularly satisfied.

The only regret is that Yang Xiuxiu is too young and a young girl, who can only be admired, not approached.

Yang Xiuxiu found that Wu Ji was looking at her, and couldn't help but be shy, Hongxia was flushed, a mantis head was hanging down, and the needlework in her hand couldn't help but slow down.

Wu Ji found that the roots of her neck were red, which was unique. If you grow up for a few more years, the mature woman's taste will become one, and such a childlike state is enough to fascinate people.

"Bang!"

There was a slight sound outside the house, if it weren't for Wu Ji's excellent ear sound, he really couldn't hear it.

Yang Xiuxiu also heard it, her pretty face was full of surprise, and she was about to ask out loud, Wu Ji put her finger on her lips and motioned her not to make a sound. Yang Xiuxiu was a clever person, and immediately understood Wu Ji's intentions, and swallowed back to his mouth.

Wu Ji's face was cold, he picked up a piece of firewood, put it behind his back, pretended to stretch his waist, and yawned: "I'm tired, I'm tired, I'm going to sleep!" It's not early, so hurry up and rest. ”

Slowly walked to the place where the sound came from, and there was a gap in the wall where cold air was pouring in.

Wu Ji put the firewood in his hand against the gap, and stabbed most of it into it.

"Ahh My eyes! A scream came from outside the house.

"Wu Liang!" Yang Xiuxiu exclaimed.

"Humph!" Wu Ji snorted coldly, he had already guessed that it was Wu Liang, except for him, there would be no second person in Zhuangzi to do this kind of thing.

When Wu Ji was still in the coffin, Wu Liang was beating Yang Xiuxiu's idea, he definitely didn't have good intentions when he came this time, Wu Ji decided to teach him a hard lesson, so he deliberately pretended not to hear it and broke out.

"Chase!" Wu Ji grabbed Chai He, rushed out of the house, looked around, and saw a black shadow in the distance fleeing in panic.
