"Well said."

Gu Hanping must have heard about this, so he rushed over.

Upon hearing Gu Yunyang's words, he quickly agreed.

He was genuinely angry at his younger brother for his lack of ambition.

How can we let an old woman ruin our home like this?

He hadn't figured out Gu Hansheng's true character yet, unaware that Gu Hansheng was actually the one hiding behind the scenes enjoying the benefits.

Ning An bore all the blame.

At most, people would say he's henpecked or afraid of his wife.

There are many men like that in the countryside.

Gu Hansheng's level is just a bit higher.

Gu Yunyang didn't want to waste any more time on this matter.

He immediately said, "Since the captain is here, then come with me."

I'm making steamed sweet potatoes today, come and take a look.

In addition, my biogas digester is already usable.

Gu Hanping was aware of what had happened before.

However, Gu Hanping was quite curious about the biogas digester: "Is it ready to use yet?"

After the biogas digester is built, manure, along with straw and other materials, will be discharged into it.

These things need to be mixed together and fermented before biogas is produced.

So-called biogas is methane.

This gas is abundant in swamps and beneath many coal mines.

Therefore, it is important to ensure proper ventilation in coal mines, one reason being to provide sufficient oxygen for the coal miners.

Another point is to remove the methane to prevent an explosion.

Gu Yunyang, carrying Daya, led the others up, saying without batting an eye, "After these few days of fermentation, it's almost done. I've also installed the electrical circuits. Once we get back and fix the light bulbs, it'll be almost finished."

When they came up, Gu Yunyang originally wanted to make steamed sweet potatoes first, but Gu Hanping couldn't wait to go and see the biogas digester for generating electricity.

Gu Hongmei was also a little curious, but seeing that Gu Yunyang was going to steam the sweet potatoes, she had to clean them first.

She had always been taken care of by Gu Yunyang and wanted to help her younger brother.

So Gu Hongmei said in her still somewhat hoarse voice, "Give us the sweet potatoes, and we'll help you wash them. Daya, come here."

Da Ya was a little reluctant, but she still insisted on getting off Gu Yunyang's side and returning to her mother's side.

Gu Yunyang actually wanted to suggest that the child come with him to take a look.

However, there's really nothing interesting about biogas digesters generating electricity.

They were washing sweet potatoes in the kitchen, where there was a light bulb.

Gu Hanping asked curiously, "Isn't anything required?"

Gu Yunyang laughed and said, "Actually, there's not much to do. I bought the light bulbs from the supply and marketing cooperative, and we can just install them. You can just turn on the light when needed."

Gu Yunyang pretended to enter the house, but actually took the light bulb out of the base space.

After thinking for a moment, Gu Yunyang said, "I'll install the light bulbs in the bedroom and living room first. Then, we'll install one in the kitchen and test the light bulb there."

Gu Hanping immediately understood what was going on.

A bunch of girls are washing sweet potatoes in the kitchen.

Gu Yunyang had taken them into consideration.

"Alright."

Because of the height, Gu Hanping was about to ask if they needed a ladder.

Then Gu Yunyang took out a foldable ladder.

What's going on here?

Gu Hanping was very curious; he had never seen a ladder like this before.

The bottom of the ladder is square, and when opened, four square base plates land perfectly on the ground, making it very stable.

Gu Yunyang climbed up quickly and installed a light bulb on the reserved light bulb base.

After getting down, Gu Yunyang explained with a smile, "I just wanted to make sure I didn't need anyone to hold the ladder when I'm home alone."

What if I fall?

So I thought I'd make two ladders, put them together, and that way someone would hold the ladder, so I wouldn't have to worry about falling.
