At the beginning, he took his seven younger siblings to join Yi Zhonghai.

When Yi Zhongding came out of the house.

The women had already dispersed.

He went over to help his sister-in-law wash clothes.

These little kids are really quite a handful.

The clothes get dirty again in the blink of an eye as soon as I put them on.

Even wearing a blouse and arm sleeves won't help.

"Sister-in-law, let me help you."

Yi Zhongding walked over and said.

"No need, you go about your business."

Tan Xiulian moved the wooden basin next to her, not wanting her younger brother to get involved.

In her view.

Whose son is good at doing laundry?

Wouldn't that make us a laughingstock?

Although she didn't have any preference for sons over daughters at home.

She treated both girls, Yaoyao and Miaomiao, equally.

They might even spoil them a bit more.

Because there were only two girls.

It's very rare.

However, she wouldn't let Yi Zhongding do chores like cooking or washing clothes.

"Everything's done, so there's no need to rush the cabinet."

Yi Zhongding said with a smile.

"Then go have some fun, either by yourself or by taking your younger siblings out for a stroll."

Tan Xiulian still wouldn't let him get involved.

"The sun will be very strong soon, don't let them get heatstroke."

Yi Zhongding said, not knowing whether to laugh or cry.

"Anyway, don't worry about it, I'll be done washing soon. If you don't want to, go with the kids. The two little ones can't be left alone. If you weren't home, I wouldn't dare leave them at home."

Tan Xiulian waved her hand and pushed him away with her elbow.

Then she added softly, "By the way, the Yan family has ulterior motives. Since you didn't agree to let their son learn carpentry from you, they've been spreading rumors that you earn tens of yuan a month."

"While you were away, a large group of women surrounded me, wanting me to agree to take their child on your behalf."

"But I'm not stupid. Teaching a disciple can lead to the master's starvation. I'll let them take advantage of our family, especially you."

Tan Xiulian spoke while smiling proudly.

"That's right. My sister-in-law can make me suffer. These people are just acting out of greed. Even if they come, they'll just mess with me for a bit and then quit."

Yi Zhongding said with a light laugh.

"I told them that we'll discuss this with you when your older brother comes back. Don't worry, with us here, they won't dare to cause any trouble."

"And the Yan family, humph, you didn't beg them to get into school, and they didn't help you either. We don't owe them any favors. We'll have your older brother deal with them later."

Tan Xiulian nodded, her eyes fixed on the front yard with hostility.

"That family is worse than a toad. At least toads are beneficial insects, they're just disgusting to look at."

"This family is disgusting from head to toe."

Yi Zhongding was indeed disgusted.

He wouldn't even use the metaphor of a toad to describe the Yan family.

Don't be fooled by the toad's ugly appearance; its skin is poisonous.

But it really doesn't bite.

The skin is poisonous as a form of self-protection.

What's wrong with this?

Moreover, even the extract from this poison is a type of medicine.

Even its entire body can be used as medicine.

This thing not only won't hurt people on its own, but if you hit it...

It won't fight back; it will just rub its eyes with its claws.

It's like telling yourself: rubbing it like this will make it stop hurting.

"Leave this to your older brother; he can handle it. Don't let people like that distract you. I'm telling you this so you can stay away from unlucky people like them."

"Just you wait and see, Yan Bugui will get what's coming to him."

Tan Xiulian said with a smile.

"Okay, I'll go back and think about it, see how to make something to make your laundry easier."

Yi Zhongding responded with a smile.

"Dingya really cares about us. But it's quite easy now. With just you and your older brother earning income, I only have to do the kitchen work. It's very simple."

Tan Xiulian smiled contentedly.

"This is not just a simple matter of cooking at the stove; you, sister-in-law, are a great contributor to this family."

Yi Zhongding said this from the bottom of his heart.

"With your words, I feel sweeter than if I had eaten honey. Don't stand here, go back."

Tan Xiulian was so happy to hear this that her teeth practically popped out.

Yi Zhongding smiled and went home first.

His words just now weren't just empty talk to make his sister-in-law happy.

Miao Miao's words last night gave him a wake-up call.

He remembered watching a video where a blogger made a hand-cranked washing machine, which looked quite useful.

He has no way to get a washing machine now.

But it's still possible to make a hand-cranked one.

But he didn't know whether a hand-cranked washing machine would work or whether it would be laborious.

He needs to make it and try it out first.

Anyway, we have plenty of wood at home.

Give it a try.

It's not a big problem if it doesn't work out.

We can afford the losses.

Thinking this way.

Yi Zhongding first went back to the house to see if his younger siblings were causing any trouble.

These younger siblings are truly adorable when they're being cute.

But when he acts like a demon, he really is just like a little devil.

Fortunately, the dolls in the house are still quite well-behaved.

They were quietly playing with their toys.

As for that brat Yi Zhonghua...

They're already having a blast playing in that wasteland in the east courtyard with a bunch of friends.

Usually when the older brother isn't around.

He would obediently watch over his younger siblings.

If my older brother were home.

He then ran off to play.

Yi Zhongding watched his younger siblings playing obediently and didn't pay any attention to them.

I reached the threshold.

Bring out the usable planks.

Now he can't buy those plastic materials from later generations.

We'll have to use wooden planks.

Yi Zhongding first drew the structural diagram of the washing machine on paper.

For a simple setup, all you need is a roller, a base, a bearing, and a crank.

But that would definitely be a lot of work.

Moreover, you can't wash too many clothes at once.

So he planned to imitate the windmills or foot-operated threshing machines used in rural areas.

Windmills are simple.

Just build that big belly and add a crank handle.

The fan blades inside are just right for stirring clothes.

However, it causes significant damage to clothing.

But a foot-operated threshing machine is different.

Its structure is similar to that of a manual washing machine.

Moreover, there's no need to add iron rings to the threshing machine drum.

It saves a lot of time.

This thing was invented precisely during this period.

It is already in use in some rural areas.

This is what he saw when he went to the countryside to support agriculture during his school years.

Although it is very simple.

But it did happen.

And this thing is also incredibly fast when you pedal it.

One careless move and you could break a person's fingers.

It should be more than enough for washing clothes.

Moreover, the threshing machine itself is just a few wooden roots embedded between two discs.

It has a built-in rectangular gap.

He doesn't even need to drill holes in the wooden board.

Saves time and effort.

And the power source...

His gaze fell upon the several energetic little children inside the room.

Two steamed buns are enough to fill a bucket of clothes.

The problem is that gears, transmission bars, and bearings need to be made of steel to be durable.

However, Yi Zhongding quickly shook his head, deciding not to think about those things for now.

It's experimental anyway.

I'll try making a few wooden gears myself first.

If it works well.

If all else fails, we can just buy it from a machinery factory.

Yi Zhongding first drew a sketch.

Then we started building a trapezoidal base with a small bottom and a large opening.

This thing needs to be filled with water.

Therefore, it must be done flawlessly.

Aside from the waste of glue, it's not difficult.

You can also avoid using glue.

The adjacent wooden planks were carved out with tracks on one side and convex shapes on the other.

Then just embed it.

Yi Zhongding was prepared to use this method.

Who would have thought that even industrial products like wood glue would be scarce in this era?
