But this relaxation is also time-sensitive.

In spring, summer and autumn, the wasteland north of the deserted city is not frozen, and the wasteland people can barely survive there, so naturally they will not come to fight the Jing army. But in winter, the deserted cities are frozen, not to mention the great wasteland north of the deserted city, and many deserted people can freeze to death in one winter.

In order to survive, the desolate people will naturally fight back into the desolate city, anyway, they are all dead, and there may be a glimmer of life if they pounce in......

After coming and going, the situation of these 70,000 soldiers and horses was even worse than that of the 80,000 soldiers and horses.

Spring, summer and autumn are fast, but in winter, the days are tormented.

Yu Shu's idea is to wait until the crops in the field begin to scion scion, and when the result is the result, he begins to mobilize idle troops to reclaim the wasteland in the deserted city, and when it freezes in winter, the reclaimed land will not be regrown with weeds and vines, and when it freezes in the next year, it can be sown with two casual turns.

In this case, the grain harvest in the deserted city will be very impressive in the autumn of the following year.

When it was not the busy season for farming, they could also spare their hands to cut down trees from the mountains and build wooden houses in deserted cities for everyone to live in, so that they no longer had to live in tents to live that hard and troublesome life.

"Captain's lady, we can understand the idea of this kind of crop, isn't it just planting when the weather is warm, and harvesting before the weather cools down. But what does this wooden house say? How cold this place is, I guess you haven't experienced it, let alone the wooden house, even the gold and silver houses can't stop the cold and biting. ”

"I know, so not only should the wooden houses be built with better seals, but it is also better to have thick curtains on the roof, windows and doorways to protect them from the cold wind. As for the inside of the house, it is impossible to use a bed like in the south, and it is still cold to lie in bed in the winter in the south, let alone here. ”

When everyone heard this, their eyes were dyed with incredulity.

"What do you sleep on if you don't sleep in a bed? Is it possible to still set up a tent in the house? ”

If the cold in the south comes from the cold and moist air in all directions, then the cold in the north comes from the earth.

If you set up a tent, what is the difference between it and the old days?

"Naturally, it's not about setting up a tent, but if that's the case, why are you wasting your time building a wooden house? I thought it would be better to build a fire kang inside the wooden house. ”

"Ondol?"

The crowd was even more puzzled, and there were those who could not read, and when they heard the word fire, they couldn't help but feel afraid.

What does the fire kang mean, isn't it burning the fire and sleeping next to it?

"It is the appearance of a bed made of mud and stone, the inside is hollow, but the surrounding is sealed, leaving a hole on the side against the wall, preferably connected to the stove in the house, in that case, as soon as the fire is burned in the stove hole, the temperature on the stove will burn along the smoke to the kang, so that sleeping on the kang will naturally not be cold."

Yu Shu's ability to describe is very strong, and by the way, he even caught up with the habits of his previous life, and his two hands were still flexible and smooth according to his description, so that a group of rough men immediately appeared in their minds the appearance of the fire kang.

The large bed exuded a fiery temperature, so warm that every toe of them was hot, and I am afraid that the taste could only be experienced when they were roasting around the fire during the day.

And on this side of the deserted city, it is actually not scientific to bake a fire around a fire.

Usually the side facing the fire is about to catch fire, but the side facing away is blown cold by the cold wind, which is simply the feeling of ice and fire.
