Zhao Xinqing was a little confused: "What should we use as a fulcrum?"
Su Bai kicked away the stone that Zhao Xinqing had moved earlier, took out half a large bamboo tube from the basket on his back, turned the bamboo tube upside down on the ground, and explained:
"This limestone is too heavy."
"If you want to pry it, even if it is made of green wood as a lever, it will be easy to break."
"So, the fulcrum must not be too hard."
"You have to have a certain degree of toughness and flexibility."
"Bamboo is the best choice."
Zhao Xinqing nodded thoughtfully and said:
"It makes sense. Bamboo can collapse and help Qinggang wood absorb energy."
After clearing away the vines on the surface of the large limestone, Su Bai took out a large bundle of thick straw ropes from his backpack, and together with Zhao Xinqing, wrapped the large limestone tightly and tightly on all sides.
Barrage:
【???】
[This operation is a bit psychedelic...]
【Why are you tying it up?】
Su Bai explained:
"Limestone is brittle."
"Once it is pried and rolled down the hillside, it will easily break."
"If it loses its current shape, it will be difficult to continue rolling."
"Bundling with straw ropes absorbs energy on the one hand. On the other hand, even if there are cracks inside the limestone, it can be supported for a longer period of time by the straw ropes."
"We don't want this stone to roll directly into our camp."
"But the closer the distance, the less laborious it will be for us to carry it later."
Barrage:
【Oh! So that’s it! 】
[The principle is similar to the rope they wrapped when rolling red pine logs.]
【Su Bai is very smart!】
After tying up the straw ropes on all sides, Su Bai and Zhao Xinqing used two green sticks on the left and right to hold the left and right sides of the large limestone.
Su Bai turned around and ordered:
"I'll count to three, two, one later."
"I'll press harder."
"But you need to put your whole body on it."
"Only in this way can the relative balance of power between the two sides be maintained."
Zhao Xinqing nodded, indicating that she understood Su Bai's plan.
As Su Bai's "one, two, three" fell, the two of them worked together!
Snap!
Two crisp sounds almost overlapping each other came out.
The big limestone shook a little and was tilted up.
Its balance was affected and it began to roll down the mountain!
Su Bai checked the two green-gang sticks and the upside-down bamboo tube, and found that there were two dents on the bamboo tube, which were pressed out by the green-gang wood.
The two "clicks" just now came from this.
However, there were no obvious signs of damage to the green-gang stick.
Zhao Xinqing patted her chest and said:
"Thank you for your foresight."
"If a stone had been used as a fulcrum and there was no bamboo to absorb energy, the damage would probably be to the green stick."
Su Bai nodded and said:
"The ups and downs of the hillside are irregular. It is difficult to roll to the bottom with one lever. It needs to be levered repeatedly."
"If the bamboo tube is broken, we can replace it."
"But once the Qinggang wooden stick breaks, we have no choice but to abandon this plan."
Barrage:
【……】
【So stable!】
[Su Bai, as steady as an old dog, appears again! 】
Sure enough, just as Su Bai predicted, the large limestone rolled down more than a hundred meters, regained its balance again, and stopped on the hillside.
Some limestone fragments were scattered along the way as they rolled down, and Zhao Xinqing carefully gathered them up.
But this time, the rolled limestone exposed the previous bottom surface, and the two started again, carefully tying up the two sides that were not wrapped with straw rope.
The two men pried it six times.
This huge piece of limestone finally successfully rolled down the hillside and stopped at a gentle position at the foot of the mountain.
At this point, the slope becomes smaller and it is no longer possible to roll such a huge boulder.
Moreover, the condition of the limestone does not allow it to continue rolling.
During the previous journey, this piece of limestone had been severely damaged, and it had been broken into seventeen or eight pieces when it arrived here. If it had not been bound by straw ropes, it would have been broken into pieces.
Watching the two people using bamboo blades to cut the grass rope bit by bit, and the scattered limestone pieces falling down, the barrage exclaimed in unison:
【this???】
【Not only shortens the distance, but also saves the energy of transportation.】
[It also uses potential energy to smash the volume of limestone, reducing the difficulty of transportation!]
[Good guy! After you finished playing with the weather, now you’re starting to play with the gravity, right???]
This place is very close to the two people's camp.
Zhao Xinqing brought the snack guy who had had a good sleep, moved it first, and burned the limestone into the earthen kiln.
The entire process of moving, smashing, and mixing only took two people twenty minutes!
Compared to the time it took to transport limestone for a kiln of cement, which often took several hours, this efficiency is countless times higher!
After firing the cement from this kiln, the two men did not continue to carry the limestone. Instead, they took the cement from yesterday's kiln and started building the wall again.
The two of them became more and more skilled in building the wall, and their speed also increased.
The four walls are more than halfway progressed, and the traces of doors, windows, and fireplaces can already be clearly seen.
The fireplace is on the east wall, protruding from the wall on both sides inside and outside, and extending to the edge of the foundation on the outside. The top is open, and a layer of mud is pasted on the surrounding cement shale to increase its resistance to burning.
It's the same structure inward.
Zhao Xinqing had never seen such a thing before and asked curiously:
"What are these designs used for?"
Su Bai pointed to the fireplace and said:
"Fires can be made both inside and outside. Generally, charcoal fires are used instead of firewood, otherwise the smoke will be too great."
"You can put a pot on it to cook and boil water."
"The main function is to use it with the earthen kang for heating in winter. It has little practical significance now. It is just to save space first."
"In the future, we will make an earthen kang next to the inner fireplace."
"Burning charcoal in the fireplace, the heat flow will pass through the flue connected to the earthen kang, heating the entire kang. If you cover yourself with a quilt, you will even sweat."
Zhao Xinqing's beautiful eyes lit up and she said happily:
“Great!”
"Just thinking about it makes me feel warm!"
Barrage:
【no……】
[Why is Su Bai almost living the dream life of a wife and children on a hot bed in the wilderness???]
[Why do I only have a hot kang in a big city? Or the electric one...]
[That upstairs is so inferior. In addition to the electric heating bed, I also have an inflatable wife.]
[Then you are not very good! I also have an electric heating pad and an inflatable wife. In addition, I also have a child that can be wrapped in toilet paper. I can barely live a complete life...]
To the right of the fireplace is the window left by Su Bai. At this time, due to the limitation of wall completion, there is only a prototype.
The two quickly used up all the cement, and the wall was raised by more than 20 centimeters.
The overall progress reached six out of ten.
It was almost noon, and the snow leopard came down from the mountain without knowing when, and came to the camp where the two men were camped, and nuzzled up next to Zhao Xinqing and acted coquettishly.
It will take several hours for the cement in the earthen kiln to be calcined.
