A small peasant girl's home is bare, but I have a spiritual space

Lin Yiran showed a trace of embarrassment on her face, and said embarrassedly: "Well, I am a little bit of a germaphobe, and every time I go to the toilet, I feel dizzy and dizzy because of the fumes.

The unpleasant smell on my body will take a long time to dissipate.

I have been trying to figure out how to solve this problem, and I have just come up with some ideas. I have figured out a few tricks and some half-baked ideas. "

When Master Yao heard this, his eyes suddenly lit up and he asked excitedly, "Miss Lin, do you really have a way to solve this problem?"

"I don't know if it can succeed, I just have a vague idea." Lin Yiran was also a little unsure, after all, this dynasty was too backward.

"Then tell me, maybe I can help you. How about you provide the plan and I'll be responsible for the implementation?" Master Yao was eager to try it himself.

"I want to install a set of drainage pipes in the squat toilet, and flush the pipes with clean water after using the toilet. Let the dirt be flushed away along the pipes with the water flow. This way the toilet will not have such a strong smell." Lin Yiran said.

"That's indeed a good idea," Master Yao said with joy in his voice.

As if he suddenly thought of something, his brows knitted tightly again, "This idea is good, but there are several technical problems. First, what material should be used for the pipes of the squat toilet?

Second: where should the sewage be discharged?

Third: What kind of connections should be used between the sewage pipes to ensure that they are tightly connected and prevent sewage from leaking out? Fourth, if the pipes become clogged over time, how should they be unblocked? "

"I have thought about this, and I think ceramics are more suitable for sewer pipes. First, the inner wall is smooth, so dirt is not easy to stick to it. Second, ceramics are not easy to rot even if buried underground.

I plan to discharge the sewage into a canyon 1 km away from our home.

As for the interface problem, I have a way to solve it, but we need to think about the blockage problem."

Master Yao nodded and said, "As far as the current materials are concerned, ceramics are indeed the most suitable material for squat toilets and sewer pipes. What about the materials for connecting pipes?"

"It's in my room. Let's go home first and I'll find it and show it to everyone."

"Okay, let's go back quickly." Master Yao started to jog, and from time to time he turned back and shouted, "Why are you dawdling? Hurry up, you young people are not as energetic as an old man like me. You must exercise well in the future."

"It's not us who are wasting time, it's Master Yao, you're still in good health!" After Lin Yiran finished flattering, she saw Master Yao running even faster.

The three of them smiled at each other. They didn't expect that Master Yao had such a lovely side. He is such a child!

Lin Yiran walked to her door, turned around and looked at Third Brother Lin, "Third Brother, I'm going back to the house to get something, you go and say hello to Master Yao and the others."

"Okay, we'll wait for you." Brother Lin San smiled gently.

Lin Yiran closed the door and fastened the bolt in one go, then slipped into the room and dragged out an oversized sack from the bottom of the shelf. She found two turnbuckles, a screwdriver and several rubber gaskets from it, and put them together in a cloth bag.

When she opened the door, she saw three people waiting anxiously at the door. "Here, these things are what I picked up when I was shopping at the market. Master Yao, please see if this is suitable for the joint of the sewer pipe." Lin Yiran handed the cloth bag to Master Yao.

Master Yao couldn't wait to open the small cloth bag, see what was inside, hold it in his hand and observe it for a while, then twist the screw a few times with his hands. As his fingers turned the nut, it became tighter and tighter. He tried twisting it in the opposite direction a few times, and the nut slowly loosened again.

Master Yao's eyes instantly lit up with surprise and excitement. "This thing is so cleverly designed. As long as it is made to fit the size of the sewer pipe, the leakage problem will be solved."

"What are these two?" Master Yao asked curiously as he picked up the rubber gasket and screwdriver.

"It took me a long time to figure it out. It should be used in the middle of two planes to isolate them, reduce friction between them and provide a sealing effect."

Lin Yiran first connected the two screws together, and then placed the gasket between the two screws and connected them again, allowing several people to observe.

The result is obvious, and it is consistent with Miss Lin’s inference.

Master Yao finally understood why Lin Yiran had so many wonderful ideas. This was definitely related to her usual ability to observe and think seriously.

"Miss Lin, this thing can indeed be used for pipe joints, but its workmanship is very fine and requires very high standards from the craftsman. We can't find a blacksmith in our town who can do such fine work." Master Yao said with a sigh.

"What should we do then?" Brother Lin asked anxiously.

"Only Zhang Qiaoshou from Kyoto could make such delicate accessories. The hidden weapons he made were extremely ingenious. Someone once offered him a high price to make a hidden weapon that could fire thousands of silver needles from different directions at the same time. He gave the hidden weapon a very poetic name, called Thousands of Pear Blossoms.

This is where the name Zhang Qiaoshou comes from.”

“We are thousands of miles away from the capital. We may not be able to make it even if we travel so far for a few parts.

It's really not worth it! Little sister, let's not use that old stone sewer pipe. It's been here for so many years, right? Besides, isn't it the same for other families?" Third Brother Lin kept persuading.

Lin Yiran burst out laughing, "I haven't finished talking yet?

Are you going to persuade me to give up?"
