365 days of wilderness survival

Yun Xin asked curiously, "Then Chu Feng, what are you doing with cement?" "

"Make a clay kang." The corner of Chu Feng's mouth raised and said softly, this is the reason why the cement is urgently made.

With Tokang, you will live a lot more comfortably in winter, at least you will not be woken up in the middle of the night when you sleep.

"Huh? Chu Feng, do you still make earthen kang? Liu Yiqiu was surprised.

There are more earthen kang in the north, and it is a powerful tool for heating when it snows in winter.

"It's simple, it's not hard to do with cement." Chu Feng said softly.

"How?" Yun Xin was also curious.

"Move the big bed out of the way first, otherwise there is no place to build a clay kang." Chu Feng said softly, the two big beds already occupied a lot of space.

"Good." The three women answered in unison, divided the work, and moved the two large beds to the wooden table, vacating the corner of the wall.

"That's just the right amount of space." Chu Feng said softly, the earthen kang he wanted to build was very large, and it had to be enough for four people to sleep together.

"What else to do?" Liu Yiqiu asked softly.

"Move some stones and sand." Chu Feng thought for a moment and said softly, picking up the sapper shovel on the side and walking outside the shelter.

"I'll help you." Liu Yimeng rolled up her sleeves and followed out of the shelter with great interest.

Chu Feng came to the yard, braved the light snow, used a sapper shovel to cut the snow layer, and then began to dig up the soil.

Liu Yimeng rummaged through the yard for stones, and after a while, Liu Yiqiu also came out and helped move the found stones into the shelter.

The girl came out wearing a cloak, holding a bamboo basket in her hand, squatted down to load the soil dug up by Chu Feng, and then moved into the shelter little by little.

Time passed slowly, more than half an hour later.

"Okay, let's go first, it should be enough." Chu Feng put away the sapper shovel, and there were two bamboo baskets beside him, both filled with dirt and gravel.

"Good." The Liu sisters answered casually, holding stones in their hands and stepping on the thick snow back to the shelter.

The large bed was removed and placed on its side against the wall, leaving room for walking, and the floor was piled with rubble and dirt, as well as many large and small stones.

"So what's next?" Liu Yimeng asked impatiently.

"Make a few cement slabs first." Chu Feng put down the bamboo basket and said softly.

He turned and left the shelter, went to the warehouse and pulled two bamboo sticks, cut them all into pieces with a firewood knife, and cut them into fifty centimeters in length and four centimeters wide.

Chu Feng squatted down, took out the rope, and formed a square frame with each four pieces of bamboo connected end to end, and fixed it with a rope.

He then found dried plantain leaves to spread on the ground, put the box on it, and then shoveled the earthen cement with a sapper shovel and poured it into the box and flattened it.

"Well, when it dries, it's a cement slab." Chu Feng said softly.

"Chu Feng, how many pieces do you have to make?" Liu Yimeng squatted down to help, fixed the bamboo pieces with rope, and then poured them into cement.

"Twenty pieces." Chu Feng said softly, the earthen kang he wanted to make was two meters by two meters and five, so that it was enough for four people to sleep together and not crowded.

Each clay board is fifty centimeters by fifty centimeters in size, which means that twenty such cement slabs are needed to cover the earthen kang.

"Howler." Liu Yimeng was busy with interest.

It took the four of them another hour to get all twenty cement slabs ready, which took up the ground and left only a small area to walk.

"There is still some cement left, which should be enough to build the kang wall." Chu Feng said softly, taking those bamboo pieces and starting to measure the distance by the wall to determine the location of the kang wall.

The kang is built next to the corner, so only two other kang walls need to be built.

After determining the location of the kang, he began to build the walls with stone, the same method as the walls of the shelter, except this time the clay was replaced with earthen cement, which was faster.

With the help of the Liu family sisters and the girl, Chu Feng spent more than an hour to build the two kang walls of the earthen kang, which were eighty centimeters high.

The two kang walls, the one facing the fireplace, have a ten-centimeter-long and wide opening near the corner, which is used to connect the fireplace and is also the entrance to heat the earthen kang.

Liu Yimeng pouted, looked at the kang wall built by Chu Feng and muttered, "It looks like a pigsty..."

"Liu Yimeng..." The corner of Liu Yiqiu's mouth twitched, and she rolled her eyes angrily.

"It's not like building it." Chu Feng smiled bitterly, carried the bamboo basket, and poured all the mud and sand inside into the position enclosed by the kang wall.

He stepped over the kang wall and went inside, carefully flattened the soil with a sapper shovel, and then covered the surface of the soil with cement evenly to prevent the heat from escaping too quickly.

After covering the cement, Chu Feng carefully stood outside the kang wall, using stones to build a flue inside.

The flue is built in an 'S' shaped manner, starting from the heating inlet, and encircling the earthen kang, the height is level with the outermost kang wall.

The reason why the earthen kang is warm is that the hot smoke is circulated under the earthen kang, and the 'S' shaped flue can make the hot smoke stay in the earthen kang longer.

Most importantly, the flue can also play the role of supporting the cement board, just as a pillar.

It took Chu Feng more than half an hour to finish the flue, and all the cement in the water tank was also used up.

"You have to wait until the cement is all dry before you can move on to the next step." Chu Feng said softly, rubbing the cement between his fingers with both hands, and the earthen kang in front of him was already half completed.

"Then I'll make dinner." Yun Xin said with a smile, reached out to wipe the cement from Chu Feng's face, and then turned and ran away.

"It's getting dark." Chu Feng chuckled and looked out the window, the sky outside had already darkened.

"Chu Feng, you go wash your face first." Liu Yiqiu said softly.

"Good." Chu Feng looked at his hands stained with cement, turned around and went to the water tank to scoop up some water, and went into the toilet to rinse.

"I'll help make dinner." Liu Yimeng ran to help the girl.

Liu Yiqiu found a broom made of branches and hay, and simply cleaned the ground where the dirt and stones had just been piled up, making room for the big I bed tonight.

"Be careful when you walk."

She whispered to the two women that the ground was full of mud tablets, and it was easy to step on them if you were not careful.
