When Zhang Ping'an heard Lu Deyin asking about Lu Zhengwen, he stopped, thought for a while, smiled at Lu Deyin slightly, and did not say anything, patted his shoulder and turned around and left.

Rudeyin read a trace of sinisterness from his eyes, nodded and watched him leave.

With Ponu City as the center, it is now rumored that the castle in the north is reborn in hell. Whenever night comes, evil ghosts scream. People scold the crying children, if they cry again, they throw him to the castle in the north, and the children immediately stop the sound. It is much better than posting verses on the toilet wall.

Zhang Ping'an stayed at Guangcai's camp for six days, gave lectures in the morning and asked the interrogators to intern in the afternoon. Seeing that the teaching results were significant, he returned to Ponu City and discussed with Wang Ermu, Li Tie and others about the manufacturing of muskets.

Now Zhang Ping'an's uncles have been appointed by him as the "craftsmen" of the Slave Army. They are in charge of several workshops, including iron tools, wood tools, brick kilns, lime kilns, and coke kilns. This time he came to solve practical problems for them.

He came to the craftsman's workshop, first greeted several uncles, and then came to the steelmaking furnace with them, and looked at the newly-baked charred wood using the residual heat of steelmaking. He was satisfied with Li Tiedao: "Uncle Li has a good grasp of the heat!"

He picked up a few steel sticks made by Wang Ermu, measured them with his own vernier caliper, and said to Wang Ermu: "Uncle Wang's craftsmanship is not the wrong one, it is the size I want! You always follow what I said, your apprentice beats roughly, are you always spoiled in the end?"

"Ping An! You've spoken, can I not listen? Your method is really good. Recently, we have made more than 800 steel sticks. We also applied grease to prevent rust according to your requirements. But the steel is too hard, what tungsten ore you mentioned? When will you give it to me!"

Zhang Ping'an smiled and said, "It's almost done! We have found tungsten ore from Jiangxi, although not many, making drill bits is enough! I'm going to expand it five times. Make good use of the drop of the waterfall here and add five hammer-made houses and six polished drill houses."

At this time, Wang Ermu's expression was a little hesitant and wanted to speak but stopped. Zhang Ping'an saw his strangeness and walked to Wang Ermu and asked, "Uncle Wang, what's wrong?"

"I want two of you!"

"Uncle Wang, whoever you want, as long as it is helpful to you, it can increase the yield. I will give you everyone!"

"Last time, Gu Xin came to me. I found that Deyin's wife and Yaxin were both accurate at first sight. We made Milu guns, and many gun barrels could not be put in, so we threw them aside to prepare to return to the furnace. These two girls selected a lot of waste gun barrels and asked our apprentices to use grinding wheels to grind the parts they pointed at with grinding wheels, and then they became qualified gun barrels!"

"There are also such divine eyes! No problem, uncle is the most important thing for the Po Slave Army!" Zhang Ping'an was quite surprised.

After Zhang Ping'an solved Wang Ermu's affairs, he came to Li Tie's scholastic house again. Check the progress of the crossbow. Li Tie pointed to the crossbow and said, "Last time, Uncle Wang, burned a pot of mild steel, and I asked him to make the key components of the crossbow. I made seven crossbows in total, and we experimented several times. A three-pound stone bullet can shoot out 270 feet! If you can reach one and a half miles, it is rare to encounter a suitable mild steel."

"It doesn't matter Uncle Li, the recorder around Uncle Wang, wrote me a report last time and told me about this. I'm going to ask Uncle Wang to try it a few more times, which should be able to solve this problem. By the way, Uncle Li! How many tortoise shell chariots I designed have made?"

"Peace! There are so many tasks you have arranged! You want more than 10,000 four-wheeled carriages and chariots. We are more than 3,000 people, so we can't be busy at all."

"Uncle Li! This is Ping An's fault. Didn't I ask you to do your homework? I see that your recorder will give me the report that you are very efficient!"

"That little kid, I'll tell you all the nice ones. The car is done very quickly. The key is that the steering wheel in front of the carriage is not easy to make! The size is a little wrong. This car cannot be used! Fortunately, you made the wind saw, which saved us a lot of effort. The chariot you want, made two prototypes. One was pushed by two cows, and one was pushed by four cows. Deyin sent someone to test it and said that the four cows are easy to use."

Zhang Ping'an picked up the kettle on the table, poured a glass of water for Li Tie, and handed it over and asked, "Why! I always thought that the two cows' cars were easy to use!"

"At the beginning I thought the same as you, but I looked at Deyin's experiment. I think Deyin makes sense. Deyin said: The chariot is used for war, and everything should be considered from the perspective of the battlefield. He said that the chariot pushed by the four cows is heavier than the chariots of two cows, but the chariots are faster and can carry more soldiers. In this way, the chariots will be more powerful on the battlefield. Deyin also proposed that the chariots must adapt to the requirements of the winter battlefield and that the wheels and sled boards can be exchanged at any time."

Zhang Ping'an said to Li Tie with relief: "We have grown up with silver! He can think about problems like this, which means that he has passed the commander! OK! Just do what he said!"

Zhang Ping'an then asked Li Tie: "Uncle Li! How are we preparing the gadgets we made for the emperor?"

"Don't worry! They are all made after charcoalization. The carvings are also made, all of them are peony, and there is no taboo. The folding tables and chairs are all covered with tung oil! Our paint is small, so let the craftsmen in the palace paint it! Xiaoyao chair is still missing. It's safe! Uncle tells you something! Your uncle Sun came to me and said that his boy wanted to go to the personal military camp. He is embarrassed to find you and ask me to tell you. Do you think it's okay?"

Zhang Ping'an asked: "Uncle Sun's son is only eleven years old, why are he going to the barracks? I think he is studying well. In a few days, I asked him to go to Guxin. The risk is still relatively small. I turned around and told him that you are all my relatives. If you have any questions, just come to me. Uncle Li! You have to give your family a name and give him a big name. You go to Long Xiucai. Xiucai has many colorful intestines and many articles in his stomach. Let him name your son. I said that this matter was something I arranged for him. If he couldn't give a good name, I would let Zhao Qiong slap him on the butt!"

Li Tie replied happily: "That relationship is good! I also think my second fool is not good at calling me like this!"

………………………………………

Zhang Ping'an left the wooden workshop and was about to go home when he saw Jia Youfu coming out of Wang Ermu's blacksmith's workshop. Zhang Ping'an shouted to him from afar: "Director Jia, why are you so idle!"

When Jia Youfu heard someone calling him, he turned his head and saw that the person calling him was Zhang Ping'an. He immediately ran over and saluted him and explained: "Master, I'm so busy. How can I have time to wander around! I went to Ermu to get the surgical tools they made for me."

Zhang Ping'an knew that he was an easy-going person and happened to think of going to the newly established Medical Office. So he said to Jia Youfu: "Let's go to your Medical Office to see you. Do you have any difficulties? Do I need me to solve them?"

Jia Youfu was a little excited: "There is something really wrong. Please help me solve it. Last time you sent me an order to find the cows with acne and let me inoculate people. I found the cows, and I gave myself to plant cows according to the method you said. But no one else dared to plant this matter except the apprentice I brought with me!"

"This matter is easy to deal with! In a few days, I called all the brothers from the personal military camp, and I was the first to plant them. Then, my wife also planted them. In this way, it can be promoted! The main thing is to disinfect them well and not let the wounds become purulent."

Jia Youfu happily slapped his high-high high: "There is a great coach who personally demonstrates it. This matter will definitely be promoted!"
