Mu Yaping greeted his mother and found that her mother was in a bad mood. He asked her mother, "Mom, what's wrong with you, or you're feeling unwell, do you want to see a doctor?" The mother sighed and said, "It's not your second brother's business. The couple is fighting again. Your sister-in-law ran back to her parents' home in anger. Alas! I just didn't want to go to my parents' home to pick him up. It's really not worry-free. Today I was so upset that I came to chat with Wanqiu."

Wanqiu is not only Mrs. Mu's daughter-in-law, but also her niece. Since childhood, Wanqiu grew up next to Mrs. Mu, and there is no difference between him and his daughter. The mother talked for a while and left. Wanqiu looked at her mother's back and said, "Cousin, what mother means is to ask you to persuade Weiping." Mu Yaping said, "Okay! I'll go and persuade him after the meal."

After dinner, Mu Yaping stood in the small garden for a while, then walked straight to his second brother's room. He pushed the door and saw Mu Weiping lying on the bed leisurely looking at a pictorial. Weiping saw the elder brother coming in and stood up and greeting him. Yaping asked, "What book are you reading?" Weiping replied, "It was a picture of the German army's equipment during World War I. I just flipped through it when I was idle."

Mu Yaping took the pictorial and flipped through a few pages, which contained a large number of black and white photos and illustrations, accompanied by German and English descriptions. Mu Yaping put the pictorial on the table and said, "Second brother, I heard from my mother that you and Jingru had a falling out again, what's going on?" Mu Weiping said angrily: "This woman bothers me every day, and she runs back to her parents' home for a little bit of trouble. I just end up in peace."

Mu Yaping said: "No matter what, you have to take into account your mother's ideas. Mother is a person who wants to save face. If your parents come to make trouble, where will your mother's face be put? I know that your personality is a bit cowardly, and your sister-in-law is a bit domineering. Since you marry her, you have to learn to deal with your relationship. I think you should take her back!"

Mu Weiping said anxiously: "Brother, I don't avoid anything. It may be difficult to say it out. Jingru's pleasing for fun every night is simply unbearable." Mu Yaping smiled in his heart: For some men, this kind of thing may not be possible. It is obvious that Weiping, who has a cowardly personality, does not like women like Hou Jingru from the bottom of his heart.

Mu Yaping thought about it and said, "Second brother, you should take your sister-in-law back! I'll be upset about your affairs. I'll give you an idea - pretend to be sick so that Jingru won't bother you every day. As for how to grasp it, you have to be a sensible." Weiping nodded with his eyes. Before leaving, Yaping suggested borrowing the pictorial, and Mu Weiping accepted it happily.

Mu Yaping returned to the house, and Wan Qiu asked, "Cousin, do you agree to bring Jingru back?" Yaping boasted, "As long as your husband takes action, you can't handle anything. Just keep your heart in your stomach!" Wan Qiu hurried to his mother's house to report the news. Mu Yaping understood Wan Qiu's mood, and at least let his mother have a good sleep tonight.

Mu Yaping lay flat on the bed and picked up the pictorial and looked it up. Suddenly, a photo of a German soldier equipped with a grenade aroused his interest. The illustration next to it also specifically introduced the performance of grenades. This wooden handle long handle and cast iron shell grenade had already begun to be used during World War I. Due to the rise of trench warfare, grenades played a great role. For grenades were used on a large scale, and they would not play a real role until World War II.

Mu Yaping thought that in the future, the Japanese army will attack on Japan, and our army will definitely play a huge role as the defender. The key is that the grenade is simple and easy to make. Although Mu Yaping has never seen the manufacturing process of grenades, he knows the principle of grenades. As the saying goes: Have you never eaten pork and you have never seen pig run?

When Mu Yaping thought of this, he suddenly became excited. If he built a grenade factory, this kind of arms transaction would definitely make money, and at the same time he would create the best conditions for the reserve of talents and technical equipment in the War of the Defence Kingdom. If he made rifles now, the first environment would not allow it, and the second technical strength, raw materials, etc. would not be a one-day effort. Mu Yaping's long-term plan was to use the future Zhongzheng rifle, which was ready-made. As for how to choose a target, it is still an unknown number.

Mu Yaping knew very well that as a businessman, if he wanted to obtain German rifle manufacturing technology and equipment, he would not be able to do it in the short term. Such things must be planned slowly. The grenade manufacturing process should be very simple. In a word, grenades are the weapon of the poor. Mu Yaping was confident that after ten years of development, he would definitely do something.

Mu Yaping became more and more excited the more he thought about it. The key to the power of the grenade is gunpowder. The principle is nothing more than the gunpowder of the hairpin device and the explosive part of the explosion. As for what kind of gunpowder is used, he recalled several explosives in later generations. Traditional black gunpowder is ready-made, but the power of explosion is obviously lacking. Phelic acid is known as **, but it is also out of date. Tienti should be the most ideal explosive, but sulfuric acid, nitric acid, and toluene cannot be obtained in large quantities. The key is that the production process is impossible for Mu Yaping at present, and it is even more difficult to detonate Tienti's mercury.

However, as Mu Yaping's long-term goal, it must start planning now. Where can I use picric acid? This kind of chemical industrial product can be imported. There should be no big problem as an industrial dye. By the way, I should go to Boai Hospital to ask Dr. Huolin to find out whether the hospital needs picric acid. Suddenly Mu Yaping's eyes lit up. Why not use Boai Hospital to build a laboratory and ask Dr. Huolin to hire several German chemistry talents to extract sulfuric acid, nitric acid and other varieties of explosives in the laboratory first to prepare for future industrial production. The key is to use Germans to cultivate talents for themselves.

After thinking about it, Mu Yaping finally decided to walk on both legs. Given that picric acid cannot be imported in large quantities, he must use black gunpowder and picric acid to produce grenades at the same time. The grenades produced by picric acid are used by themselves, and the grenades produced by black gunpowder are taken out. Thinking of this, Mu Yaping could no longer sit still, so he got up and went to Bi Chengen's room next door.

Bi Chengen, who was sleepy, got up in panic and said, "Master Mu, are you asking me for trouble?" Mu Yaping sat down and said with great enthusiasm: "How are you familiar with Ma Quan in the capital recently?" Bi Chengen replied, "I am almost familiar with the main streets of the capital. I wonder what Master Mu asked me to do?" Mu Yaping said, "You can find a shop to make firecrackers tomorrow and try to buy it." Bi Chengen asked in surprise: "Master Mu, the firecracker business is small and profitable, and the sales volume is very small. I don't think such a small business is interesting. I don't understand why Master Mu is rich and powerful, so why do you think of doing the firecracker business?"

Mu Yaping said: "As for why you want to do the firecracker business, you will know in the future. Don't ask anything. Your task is to set up a firecracker shop. I have a plan in my mind now, and you will be in charge of the firecracker business in the future." Bi Chengen's face appeared sorrow, and it was obvious that he was worried that the firecracker business was not easy to do.

The next day, Mu Yaping and Bi Chengen took a separate action. Mu Yaping took a car to Boai Hospital. When they met, Huolin said politely: "Mr. Mu, why did you run away from me today? Are you asking me for trouble?" Mu Yaping said: "Mr. Huo, you said it well. I have something to ask you. I want to ask you if our hospital needs picric acid in medical treatment?" Dr. Huolin replied: "Picric acid is used as a surgical astringent, but the dosage is not large. Mr. Mu, what are you asking about this?"

Mu Yaping lied and said: "At present, a printing and dyeing factory commissioned me to buy picric acid, so I want to buy it from Germany through Mr. Huolin." Huolin replied: "Picric acid can be used as explosives production, and imports have been strictly controlled. I can only import about one ton per year. If I import a large number of them, I can't do anything." Mu Yaping said: "One ton is OK, Mr. Huolin will ask you for this matter."

Mu Yaping continued: "In addition, I want to build a laboratory in Boai Hospital. If we can produce our own medicine in the future, the profit will be unimaginable." Dr. Huolin's eyes lit up and said: "Mr. Mu, you think a lot. I can fully meet your requirements, but it takes funds to build a laboratory and hire people. I don't know what Mr. Mu plans to do."

Mu Yaping knew what Dr. Huolin meant. Building a laboratory and hiring people to conduct experiments is a long-term investment and has no benefits in the short term. To be honest, it is a loss-making business for a long time. Dr. Huolin is unwilling to take risks in this regard. Mu Yaping smiled and said, "I will bear the costs of building a laboratory and hiring people, as well as the costs of engaging in experiments for a long time. I promise to share the drugs we develop ourselves in the future."

Dr. Huolin was very happy and said, "Oh! Mr. Mu, you are simply my lucky messenger. I completely adopt your suggestions. I wonder how many people Mr. Mu needs?" Mu Yaping said casually: "You must hire 5 chemical engineers, and I can hire other personnel in China." "Okay! It's a matter of determination." Huolin agreed readily. Mu Yaping didn't have to worry about the rigor and pragmatism of the Germans. He believed that as long as the Germans agreed, they would do it well in quality and quantity.

Bi Chengen walked around the bustling area of ​​the capital and asked dozens of fireworks shops, but none of them sold, which made him extremely depressed. The driver who had been pulling him away for a day said to him with a frown look: "Shopkeeper, did you not see the firecrackers you like when you go in and out of the fireworks shop all day?" Bi Chengen said depressedly: "To be honest, I want to buy firecrackers! I want to buy a fireworks shop, but I don't expect that no one will sell them."

The coachman said, "Why didn't you say it earlier? Coincidentally, I know a fireworks shop is going to sell it." "Where is where, please take me to see it." Bi Chengen was anxious and immediately urged the coachman to leave quickly. On a not-so-broad street, the door face of a fireworks shop, called the fireworks shop, appeared in front of Bi Chengen. Sure enough, there was a notice of sale next to the door face.

After seeing this, Bi Chengen opened the door and walked in anxiously.
