Come here these days, everything else is easy to say, but it's inconvenient to go to the toilet! No, just now I suddenly thought of a small video I watched before, an old farmer made his own paper at home, no electricity at all, purely handmade, although it is not as good as what is sold in the supermarket, and it is not good to use it to write, but it is completely okay to use it to go to the toilet. Cai Xiaolian continued.

"Don't use electricity? What's that for? Gu Nian asked.

"It's like putting a windmill on the roof and braking the windmill. Among them are pulverizers, filters, rollers. It's all windmills on the roof. The material is just leaves, branches, straw or something, as for the specifics, I don't know. How about it, girl, the folks who farm the land can get it out, can you be a doctoral student? Cai Xiaolian had already settled the game at this time, and asked when she came out of the toilet.

Gu Nian took two steps back and pondered for a while: "I'll get up tomorrow and think about the principle of this." It is feasible to convert wind energy into kinetic energy, but this crusher, filter, and roller are not so easy to make at once. I'll give it a try! ”

"Okay! With your words, it's done! Cai Xiaolian said with a smile.

The mother and daughter returned to the kitchen, and saw that Gu Xin was already yawning, and the family of four covered the spark with ashes, and went to sleep.

After that, no one got up again.

……

Early the next morning.

The vegetables in the vegetable field in the yard were all ripe, Gu Nian was preparing breakfast in the kitchen, and the other three picked peppers.

After the peppers are picked, they are rinsed with water and then put in the Houyang ditch to dry, and they can be slaughtered and put in the jar at night.

"Dad, mother, Xinxin, I have something to discuss with you." While eating breakfast, Gu Nian said solemnly.

Seeing that she was quite serious, the other three didn't move their chopsticks and looked at her.

"It's about this cake, if the shopkeeper Cheng can see it, let's sell him the recipe for making the cake. We still make our own slag sea pepper, and we will talk about it after doing it for a while. The main thing is that this egg white is too laborious, Dad doesn't want to study, I also have something to ponder here, we have to maximize the benefits, we can't just make cakes to make money. Gu Nian said.

It was decided after much deliberation last night.

Didn't Cai Xiaolian ask her to make paper last night? Then there are no ready-made crushers, rollers, and filters, and she has to tinker with them herself.

This paper has to be used every day, and the family has to go to the toilet every day, especially after pulling poop, and I am really not used to using it here.

"The cake is indeed not dregs and sea peppers are convenient. What Nian Nian said also makes sense! Gu Shouxin pondered for a while and said.

"Niannian, are you going to give it a try I said last night?" Cai Xiaolian's eyes lit up and said.

"Sister, I'll help you with whatever you do!" Gu Xin showed a big smile to Gu Nian.

"What did you two say last night?" Gu Shouxin asked curiously.

"It's hand paper. The mother said......" Gu Niangang was about to explain, but was interrupted by Cai Xiaolian.

"Ahem, her father, when we make it, won't we know?" Cai Xiaolian took care of Gu Xin, after all, she had always used the toilet, and suddenly said that she was not used to it, and the little girl would definitely have doubts.

Gu Shouxin understood at once, the two of them went to the toilet together last night, and he didn't know what they said at that time.

It seems that the toilet paper is related to cleaning oneself after going to the toilet.
