After the previous experiments, Bai Guoguo thought that he would be able to win at least once if he was not perfect, even if he was not perfect.

It's like building a house, it's like doing all sorts of other things.

However, the truth gave Bai Guoguo a resounding mouth.

Not only did the ondol smoke everywhere, but it only took one night before it collapsed.

Such a fire kang, let alone live people, even sitting people is a problem.

"It's really weird, the adobe bricks are fine, and the order is also according to what is written in the book, why can't a little fire work?"

Bai Guoguo stood in front of the collapsed ondol, frowning tightly and touching his chin.

Heavy Wing stood aside and didn't speak.

Like this kind of work to find loopholes, he really can't help.

"Come, cut all the noodles, let's do it again."

Bai Guoguo waved his hand, stepped forward, and a hoe appeared in his hand.

Just as she was about to swing, a large hand grabbed her wrist.

"Leave this matter to me!"

Chongyi said, directly snatching the hoe from Bai Guoguo's hand.

Looking at the back of this man working, Bai Guoguo was a little stunned, and then reacted and hurriedly advised: "You light, don't dig out the pit of the soil surface underneath." ”

"Hmm."

Heavy Wing answered.

As the hoe in Chongyi's hand fell and got up again, the originally tiled kang surface appeared one after another, and it was quickly practiced.

Except for a few adobe bricks that were broken in the first two blows, the rest of the adobe bricks are in good condition.

Even if there is a little soil left, it is only a thin layer, and it will fall down at the slightest touch.

With such a control power, Bai Guoguo was dumbfounded.

"It's really more than goods have to be thrown, and people have to die more than people!"

Bai Guoguo muttered, walked aside, sat on the fishing chair, took out the book and continued to read, pondering the reason why the fire kang was unsuccessful.

A fire kang, ginkgo fruit and heavy wings tossed for three days, and finally made the final product.

Looking at the green smoke coming out of the chimney, which was blown away by the wind in an instant, Bai Guoguo suddenly felt a little emotional.

"I must have been a joker in my last life."

"What's a comic?" Heavy Wing suddenly spoke up and asked in a low voice.

Bai Guoguo glanced at him, shook his head, and continued to look at the green smoke that was blown away by the wind.

"Now that the kang has been built, you can go and build it for the leaders tomorrow! I went back to my vegetable garden. ”

In the past three days, Bai Guoguo has been busy with the fire kang, and he didn't bother to take care of the vegetable garden.

However, the existence of the vegetable garden is very mysterious to the people in the tribe, and it is even suspected of being poisonous.

Bai Guoguo didn't have time to teach them one by one, so the final picking work naturally fell on the shoulders of Bai Guoguo alone.

"yes, okay."

Heavy wing has no intention of objecting at all.

When it was dark, the whole tribe gathered around the fire and waited for dinner.

"Heaven and earth are yellow, and the universe is desolate. The sun and the moon are full, and the sun and the moon are full. ”

A group of primitive people, dressed in leaves and animal fur, sat by the fire, shaking their heads and reciting the "Thousand Character Text".

While turning the venison on the fire, Bai Guoguo listened to the recitation of the crowd, but he couldn't help but want to laugh in his heart.

Previously, she had taught these ancient people to recite the Three Character Sutra.

Months have passed, and there are already people who can recite it very fluently.

During this period, some knowledge of numbers was interspersed.

As long as more than half of the people are familiar with this knowledge, the ginkgo fruit will change the teaching content.
