Chapter 9: Admit

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

"The meal is ready?" Wu Ji wanted to prepare his weapons immediately, so he was in the mood to have a meal.

"It's fine if you don't need oil to stir-fry." Yang Xiuxiu said, busy serving rice. A bowl of rice was placed in a bowl, served to the table, and then helped Wu Ji over and sit.

"Where are you?" Wu Ji looked at Bai Rice without moving his chopsticks.

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

"Don't I know you yet? Go and get the bowl." Wu Ji's face sank and he was very domineering: "When did you give me the dry food? You're eating thin food? You're just when you're growing, that won't work!"

"Wu Lang, I really..." Yang Xiuxiu wanted to say something else.

"Stop talking!" Wu Ji's face darkened and his tone became a little stern.

Yang Xiuxiu was stunned for a moment, then went into the room to get a bowl. Wu Ji put the bowl in front of him, poured most of the dried rice into her bowl, and pushed it in front of Yang Xiuxiu.

Yang Xiuxiu looked at the dry rice in the bowl, tears rolling around and almost burst into tears. In her mind, Wu Ji was a scholar and a supreme existence. Wu Ji gave her the meal. Although it was care and touched her, she was very worried and could not bear it.

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

"Yeah!" Yang Xiuxiu nodded slightly, holding the bowl, crying silently while chopping white rice.

Wu Ji sighed inwardly and started to stew the rice. After a few strokes, he put the bowl on and went to the utility room, took out the saltpeter and sulfur, and prepared to stew the gunpowder.

"It's finally useful!" Wu Ji looked at the saltpeter and sulfur in his hand, which was very comfortable.

When Wu Ji saw these two things, he thought of using gunpowder. However, he didn't know where to use them. Later, when he heard about the bear, he couldn't find a clever way to detonate. Now, this problem has been solved and it is time to make good use of it.

"How to do this?" Yang Xiuxiu packed up the dishes and chopsticks, rushed to Wu Ji, and asked curiously.

"First of all, you need to boil the saltpeter and remove the impurities in the saltpeter. The saltpeter has been surviving, but it is impossible to do it. There are still a lot of debris. This is easy to do, a basin of hot water and a piece of linen cloth." Wu Ji looked at the saltpeter and saw some impurities in it.

Since the invention of gunpowder, our ancestors have been trying to improve its power. One of the most important ways is to boil nitrogen. In the first time when gunpowder appeared, such as Sun Simiao and Qingxuzi, they were burned with fire, which is actually a way to remove impurities.

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

The technology of boiling nitrogen was not very mature during this period. There were many places where boiling nitrogen was produced in the Song Dynasty, and Sichuan Jiangyou was the most important place for producing nitrogen. Here, the ruins of the Song Dynasty's boiling nitrogen are still preserved.

Wu Ji plays a lame man Duan, who sits on the ground and uses the method, but does not move. When he said that, Yang Xiuxiu hurriedly went to get a clay pot, put it in clean water, and put it on the side of the fire to hot water.

Just after the water was heated up, Yang Xiuxiu took another torn dress, made of burlap cloth, and stacked one patch by one. After a little estimate, there were no less than thirty or twenty. With Wu Ji's guidance, folded it a few times to make a filter cloth.

Finally, I found a container and after filtering it, I needed something to pack it. These things were very worn and barely useful. Wu Ji felt a little sad. The family was too poor, and only a girl like Yang Xiuxiu was willing to marry her. If it were in modern society, even if she was a doctor, she was so poor, no girl would be willing to stay by the side of a waste.

The matter of boiling salt can be done by studying junior high school chemistry, and it is not difficult at all. When the water is hot, Wu Ji pours saltpeter into it and stirs it with a small wooden stick.

It was almost done. As soon as Wu Ji said, Yang Xiuxiu picked up the clay pot and slowly poured it on the filter cloth according to Wu Ji's instructions. With the sound of water, liquid flowed into the container, and the impurities were in the filter cloth, and there were still a lot of impurities. There were not many impurities, but they appeared as soon as they were filtered, and there were so many.

The filtering is completed quickly. Next, it is boiling, that is, the process of enriching, and you just need to put it on the side of the fire and heat it. The only thing that is unpleasant is that the smell is a bit unpleasant, but fortunately, it can be tolerated.

Taking advantage of this, Wu Ji was preparing to grind the charcoal finely and prepare. The sulfur did not need to be treated, just prepare the charcoal, and once the saltpeter was ready, it could be filled with gunpowder.

Yang Xiuxiu rushed to work again and grind charcoal under Wu Ji's guidance. This was a physical job. Although Yang Xiuxiu's body was much stronger than Wu Ji, she was tired and sweating before she finished it.

Look at the sauna in the jar, you can't simmer it anymore, so you have to let it dry on its own, otherwise, it will be ignited by the fire, and it will be in vain.

Yang Xiuxiu poured out the saltpeter and spread it out according to Wu Ji's instructions, making it thinner, occupying a piece of land for the eldest son. In this way, the contact area was increased, which facilitated the evaporation of water and dried quickly.

Yang Xiuxiu's face was covered with a lot of charcoal, and her pretty face was pitch black. She was almost at the bottom of the pot. She washed two large basins of water before she washed her face white and tender.

Wu Ji was very excited and had no sleepiness at all, so Yang Xiuxiu had to accompany him. Yang Xiuxiu was a person who couldn't sit still, so she took the money for needlework and started to do needlework. She was skillful and had needlework and was very popular in the village. When people in Wujiazhuang had needlework, they asked her to do it.

She was also happy to help this kind of thing, she could change some food and get favors. When she needed help, everyone in Wujiazhuang was happy to help.

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

A black shadow appeared quietly, tiptoed outside Wu Ji's house, his eyes leaned against the hole in the wall, peeped into the room, and his eyes emitted strange light from time to time.

Wu Ji was bored, and could only admire the young girl who passed the time under the lamp. Yang Xiuxiu had just washed her face. Her pretty face was white and clean, as pink as tender lotus root, and her eyes were watery and very energetic. She also had petite figure and unique charm.

Buddha wants golden body and people want clothes. If you put on beautiful clothes for Yang Xiuxiu, you 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 time travel seems to be a profit! Not only did you pick up a beautiful wife for free, but you are also such a hardworking and kind person." At this moment, Wu Ji was particularly satisfied.

The only regret is that Yang Xiuxiu is too young and is a young girl who can only appreciate it but not get close to it.

Yang Xiuxiu found that Wu Ji was looking at her, and couldn't help but feel shy. The red clouds swelled up, and her head was hanging down. The needlework in her hand couldn't help but slow down.

Wu Ji found that the roots of her neck were red and had a unique charm. If she grew up for a few years, her mature womanhood would be a must-have, and such a childlike manner would be enough to fascinate people.

"Bang!"

A slight sound came from outside the house. If Wu Ji hadn't had the excellent ear sound, he wouldn't have heard it.

Yang Xiuxiu also heard it, her pretty face was full of surprise, and she was about to ask. Wu Ji's fingers were placed on her lips, indicating that she would not speak. Yang Xiuxiu was smart and immediately understood Wu Ji's intention. She yelled at the edge of her mouth and swallowed it back.

Wu Ji looked cold and picked up a piece of firewood, carried it behind his back, pretended to stretch his waist, and yawned and said, "I'm tired, I'm tired, I'm going to sleep! It's getting late, so hurry up and rest."

I slowly walked to the place where the sound came from, and there was a gap in the wall, and cold wind was pouring in through the gap.

Wu Ji put the firewood in his hand towards the gap and stabbed most of it hard.

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

"Wu Liang!" Yang Xiuxiu screamed in surprise.

"Hmph!" Wu Ji snorted coldly, and had long guessed that it was Wu Liang. Except for him, there would be no other person in the village to do such a thing.

When Wu Ji was still in the coffin, Wu Liang was trying to beat Yang Xiuxiu. He must have no good intentions when he came here. Wu Ji decided to teach him a lesson, so he deliberately pretended not to hear it and started a sudden attack.
