Han Cheng is now just like the old lady who makes a living by guarding chicken butts in later generations. When there is nothing to do, he runs to the chicken coop.

But there are some differences. Those old ladies guard the chickens in the hope of exchanging the eggs for needles, thread, matches, salt and other things to supplement their family income, while Han Cheng does it purely for food.

By now, Han Cheng completely understood the feelings of Wu who often ran to the rabbit circle.

Maybe the female pheasant was laying eggs in the last few days, or maybe all the eggs it laid were taken away by the ferocious little monkeys, so it wanted to lay more eggs for incubation. In any case, it has been laying eggs non-stop these days.

This made Han Cheng very happy.

After recovering from the initial shock, the old rooster with the bald tail also got along well with the female pheasant with half of its butt exposed.

Of course, this also has a lot to do with the fact that there are no other hens in the chicken coop, otherwise why would this guy close his eyes?

As the saying goes, "Extreme joy leads to sorrow, and everything turns to its opposite when it reaches its extreme." Just when the Green Bird Tribe was immersed in the joy of easily obtaining prey, a trouble quietly arrived.

It wasn't another tribe that was attacking, but the first house that was about to be completed.

From digging the foundation to laying the tiles now, everything has been basically going smoothly. When it seemed that all the tiles on the roof were about to be laid, something went wrong. A detail that Han Cheng had never considered before arose and became a stumbling block.

After the unremitting efforts of the eldest brother and others, the tiles on the house have been laid, and a row of tiles have been placed horizontally on the roof. The whole house can now be said to be basically completed, and only some details remain.

The problem arose at this time, which was the roof of the house leaning against the gables on the east and west sides.

According to the practice of later generations, two or three layers of tiles should be put on here in reverse order, and the seams should be finished with lime or cement.

This is what Han Cheng didn't consider.

Mud can be used as a binder in other places, but not here.

Because this is the roof, which is exposed to wind and rain, using mud to replace it would be irresponsible to the house.

After a few rains, the mud in the seams will be washed away by the rain, and in the process rainwater will seep in through the gaps, causing the house to leak.

The most important thing is that the leaking parts are the east and west gables, which are made of mud, and the roof is supported by wooden beams, not steel bars...

After such a detailed calculation, the problems in small details become big problems that affect the overall situation.

Han Cheng was scratching his head, wondering why such trouble suddenly happened?

I have no plans to burn cement or lime.

After thinking hard and failing to come up with a good solution to the problem, Han Cheng had no choice but to ask his senior brothers to stop and not to finish the work. Instead, they should build an earthen kang in the room on the east side according to the method he taught them.

Han Cheng would of course make a kang, a magical device for wintering.

He took some people with him and searched for traces of limestone around the tribe.

The reason why Han Cheng had not mentioned things like lime and cement before was that the tribe’s productivity was limited. The most important thing was that burning these things required very high temperatures, and ordinary firewood might not be able to do the job. It was necessary to burn charcoal first and then use it to burn lime.

If possible, a bellows needs to be made...

It is really difficult for the Qingque tribe to manufacture a bellows.

Moreover, Han Cheng only had a vague understanding of charcoal burning. He only knew that it seemed like putting out the burning wood, and then somehow it turned into charcoal.

Han Cheng deeply hated himself for devoting most of his free time to those old people in the island country in his previous life, and not watching more primitive survival videos and knowledge. Otherwise, he would be able to live more comfortably now, and would not be stumped by charcoal, lime bellows and other things...

Han Cheng's worries about things like charcoal and bellows became unnecessary.

It was not known whether it was because God no longer favored Han Cheng, the time traveler, but accompanied by the adults in the tribe, he spent ten days touring the area of ​​nearly ten miles around the tribe, but found no trace of limestone.

Looking at the almost finished roof, Han Cheng felt upset. Even though he didn't have obsessive-compulsive disorder, he felt uncomfortable looking at it. If it were someone with obsessive-compulsive disorder, he would definitely collapse...

The earthen kang in the room has been built. It is 1.8 meters long and 1.5 meters wide. Compared with the bed made of hay, which was less than one meter wide and where Han Cheng slept in the inner cave before, this earthen kang is much taller.

By then, Han Cheng can roll over and do somersaults on it.

The earthen kang is against the easternmost gable. When the house was built, Han Cheng had someone leave a hole about 15 centimeters in diameter there.

The hole is about one meter and two meters from the ground.

This is the reserved hole for smoking.

After the earthen kang is built, use adobe bricks and mud to build a hollow passage along the hole left at the back of the kang and along the wall to discharge the smoke from the hole to the outside.

In this way, there will be no smoke in the room when it is time to heat the kang.

In the west room, there is an earthen kang of the same specifications. That is Han Cheng's kang. The one in the east room is for Wu to sleep on.

The reason for this arrangement is because this was the rule in Han Cheng’s hometown in later generations.

When living in the same house with elders, the east wing is the most prestigious one, as it is where the elders live, while the west wing is for the younger generations.

If the house faces east and sits west, the north wing is the most prestigious.

Wu was a person Han Cheng respected, and he was also old, so Han Cheng wanted him to live in the east wing. This was a way of expressing his respect for him, and it was also a way for Han Cheng to commemorate the future generations to whom he could never return.

After searching for another two days, there was still no trace of limestone. It started raining again. Looking at the large area on the upper part of the west gable that was soaked, Han Cheng had to bow to reality and decided not to think about the limestone for the time being.

First use mud to fill this side and make the gap.

At worst, I can just fix it later.

Thinking of this, although I felt a little unwilling, I felt more relieved.

It turns out that nothing is difficult in this world, as long as you are willing to let go...

"Boom, boom, boom."

Several of the eldest brothers were holding tamping tools and pounding the floor of the newly renovated room.

The soil in the room needs to be rammed, so that it will not easily become loose soil later, and it will not easily cause the embarrassing situation of grass growing out of the ground in the room.

It's raining now, so there's nothing we can do outside. It's a good time to tamp the floor in a room that's protected from the rain.

After the ground was compacted, Han Cheng had someone bring a lot of dry firewood. He burned both kangs and also lit a fire in the middle one. This would help get rid of the moisture in the room faster.
