They were busy until it was completely dark, and then everyone went to the yard to thresh the rice. Every household gathered around a bucket-shaped rice bed and kept beating it to make it fall off.

After harvesting the rice, it needs to be dried in the sun for a day or two before it can be husked. There is nothing wrong with these steps, but Lin Wanwan learned that they require all the manpower here and have no farm tools. How tiring it must be!

Lin Wanwan felt that it was necessary to make a windmill and a water mill, that is, a water windmill that could pound anything.

She hurried home and looked through Tiangong Kaiwu, trying to reconstruct the specific steps, but some details were not particularly clear and she couldn't do it herself. After working for most of the day, she still didn't understand anything.

By the way, she can ask 857 if he knows!

"857! 857! I have something to talk to you about!"

"What's up Wanwan? 857 has already gone to bed..."

Lin Wanwan: ...

Well, it is retired after all.

Lin Wanwan pointed at the Fenggu Machine and the Water Pestle in the book and said, "857, do you know the specific drawings of these two things? I want to make one and give it a try."

"Wait, 857 scan it... OK, there are blueprints of these two types in 857's database, but they require 200,000 energy points to exchange."

Lin Wanwan:!

"I just paid you back 10 million energy points, how can there be any left?"

"Don't worry, Wanwan. 857 is not going to skin you alive. Wanwan can pay it back in three months, so I'll give you these two drawings first!"

"Huh? How can you be sure that I can pay it back in three months? What if I can't?"

"857 has calculated that if Wanwan's Luzhu opens 50 stores, the debt will definitely be paid off within three months!"

"Oh, you've already thought about it, no wonder you dare to give it to me."

"Hey, 857 has already put the information in the space. Wanwan can go in and get it later. 857 needs to rest. Good night!"

Tsk, this 857 actually went to bed earlier than her! It was so comfortable. She also wanted to live a retired life!

Lin Wanwan went to the space to look for the blueprint and found 857 thrown on the ground at the door. She picked it up speechlessly and looked at it under the light.

The drawings given by 857 were very comprehensive. Even though she was a novice in handicrafts, she had the confidence to make it.

Lin Wanwan went back to her room and found the brush she used to practice calligraphy. She cut a piece of drawing paper and drew the decomposition diagram with the brush. She had practiced calligraphy for a while and had also studied Chinese painting, so it was easy for her to draw a diagram.

After finishing the drawing, I would pick it up to check if there was anything missing, then let it dry, fold it, and go back to the room to sleep with the drawing in my pocket.

The next day, Yuying came to call her early again, and took the things and went to the county town together.

As usual, they were sold out early, and Lin Wanwan drove her donkey cart to look for the carpenter’s shop, owner Qian.

Qian Mao thought she was here to ask for tables and chairs, and hurriedly said, "Miss Lin, the tables and chairs you want will take another six or seven days to be completed. Please wait a few more days!"

"Manager Qian, I'm not here to ask about the tables and chairs today. I want to ask for your help."

"Oh? What can Miss Lin do for you? Just tell me. I will definitely help you as long as I can!"

Lin Wanwan took out the blueprint of the water mill and showed it to him.

Qian Mao asked in confusion: "Miss Lin, what is this? It's so amazing!"

"This thing is called a water mill, also known as a water windmill. I wonder if Manager Qian can take on this job?"

Qian Mao said in embarrassment: "Miss Lin, I am currently working on your tables and chairs, and I really can't spare the time."

"How long will it take to build this water mill?"

Qian Mao looked at the blueprint again and asked her, "The water mill you want to build should be quite large, right? We also need to build a house. If we hire craftsmen together, it will take at least a month."

Lin Wanwan nodded, "Then when the tables and chairs are finished, can Shopkeeper Qian take over?"

Qian Mao picked up the account book and took a look. "There won't be any big jobs next month, so you can take it."

"Okay, I'll come find you then."

Lin Wanwan came out of the carpenter's shop, went to the butcher's shop to get some pig offal, and then took Li Yuying home.

After returning, she still went to the fields to help pull rice. Today, Uncle Youcai also drove a ox cart to help. With two carts, the efficiency increased significantly.

Just like yesterday, Lin Wanwan sent lunch to Sister Yuying and the others at noon, and also sent some green bean soup to everyone. In the afternoon, she sent Sister Lin and the others to the river to cook the pig offal, and then went to help in the fields.

In the evening, she took the drawings to see the village head.

The village head and his friends had just finished their meal and were about to go to the yard to thresh rice when they saw Lin Wanwan coming and called her in to sit for a while.

Seeing that she seemed to have something to ask him, the village head asked, "What's the matter, girl? Do you have something to ask me?"

Lin Wanwan took out the blueprint of the Fenggu machine from her pocket and showed it to him while saying, "Li Zheng, you may not believe this, but a few days ago I fell into the water and was almost burned to death at night. Suddenly I had a dream. In the dream I met an old immortal who showed me a lot of strange things and delicious food, and told me how to make them. He taught me how to make this pig offal."

The head of the village found it a little unbelievable. "What a wonderful encounter! No wonder you can cook pig offal so deliciously. That's how it is! You are a girl who will be blessed in the future!"

"Last night, I don't know if it was the old immortal who told me a dream, but I dreamed of something called a windmill, which is used to separate chaff, dirt and dust. Pour the freshly threshed rice into this bucket, open the baffle, and turn the windmill by hand, and then the rice can be separated. It saves a lot of effort."
