After lunch, Su Bai and Zhao Xinqing looked at the sky and found that the sun shone through the clouds, and there should be no rain in a short period of time.
"We... made the foundation first?" Zhao Xinqing asked Su Bai's opinion.
Su Bai shook his head and said:
"I don't know when it will rain, but it's likely to be within five hours."
"The cement needs to be thoroughly dry and it takes a long time."
"If you build a foundation now, there are great risks."
"We'd better go and dig shale, now is a good opportunity."
Zhao Xinqing responded and turned to pack up her things.
When taking the tools, Zhao Xinqing hesitated and asked:
"What tools do we bring?"
Su Bai shook his head and said with a smile:
"The tools we have on hand are not easy to use."
Zhao Xinqing obviously discovered this problem.
Do you use a stone axe to chisel shale?
Too nonsense?
The barrage is also talking about it:
[I feel that it is more reliable to wait for the next hail...]
【Emmmmmm…Bamboo may be used…】
【Bamboo? How to use bamboo?】
Su Bai looked at the barrage and nodded and said:
"Bamboo was my first thought."
"Most of the stacks of shale are not particularly close."
"Use thick and short bamboo nails to nail in, and then pry them up, and it will be a piece of shale."
"But this will be very laborious and requires a lot of shale structure."
"Some tight rock formations cannot be obtained in this way..."
Barrage:
【What do you think now?】
【Is there any slutty operation?】
Su Bai laughed twice, took out several pieces of green charcoal from the bamboo shed, and showed it in front of the camera:
"Bring the fire."
"Most stones, after being heated to a sufficient temperature, will burst."
"The ancients often used this phenomenon to obtain the fragments of stone they needed."
"Of course, the efficiency is not high. If large-scale stone is needed, the ancients would still use iron hammers and iron chisels."
Barrage:
【…】
[In this case, why did your initial idea not to burn it with fire, but to pry it with bamboo?]
Su Bai said "hey" and said with a smile:
"I have to thank the rain for the last few days."
"The ancients would water the stones a lot before heating them, but we didn't have wooden barrels and couldn't carry a lot of water, so we could only rely on God."
"After continuous rain, a lot of rainwater will penetrate into the shale layer."
"After heating with green charcoal, the rainwater will quickly turn into water vapor inside the shale."
"It will be much easier to trigger a burst because of the rapid expansion of the volume of its internal moisture."
Barrage:
【???
[God: Free sex always happens in unexpected moments.]
【God: You have a lot of poses for free…】
[God: I have decided that I won’t be around you in the future!]
Zhao Xinqing heard her beautiful eyes radiate, nodded repeatedly, and said:
"That's right!"
"Su Bai, why are you so smart!"
The two had a mature plan, pulled the foodie, brought a shoulder pole and fire, and once again came to the gentle shale hillside.
Su Bai used the bamboo blade and stone axe to split the large pieces of green charcoal they brought into half the size of a fist, and piled them together to ignite them with fire.
Then the two used bamboo slices as chopsticks to pick up the hot green charcoal and spread them on the surface of the hillside.
After placing the green charcoal, Su Bai quickly pulled Zhao Xinqing and the snacker and hid in the woods aside.
Although rock bursting will not have too much lethality, it cannot be too careless.
As the green charcoal burned, strands of white water vapor rose from the surface of the shale and floated towards the sky.
Zhao Xinqing covered her ears and hid in Su Bai's arms. Her beautiful eyes were wide open and she stared at the hillside not far away.
But after several minutes, I still didn't hear any bursting sounds.
Zhao Xinqing couldn't help but wonder:
"No...no effect?"
Su Bai smiled and said:
"It takes a certain amount of time for heat to penetrate into the stone..."
A few minutes later, a not-sounding "Bang!" exploded on the hillside.
There was no movement, but I could vaguely see a piece of green charcoal ignited with dark red light jumping, as if some force was pushed from below.
After the first explosion, there were relatively dense crackling sounds, which sounded one after another from various areas on the hillside in front of me.
Occasionally, some gravel will splash out, making the surrounding grass and trees "rustle".
After more than half an hour, the explosion gradually ended.
The two of them pushed apart the plants and came out of the woods.
On the hillside, fragmented shale pieces are scattered everywhere.
Zhao Xinqing said in surprise:
“It’s really useful!”
"So many shale flakes are enough for us to move several times!"
Su Bai and Zhao Xinqing were picking on the hillside, smashing the too big and throwing away the too small, and soon half of the shoulder pole and the backpack were installed.
Because of the weight of shale flakes, they can only fill half of them.
If it is full, not only will the back be moved, but even the shoulder pole and the backpack may be broken.
The foodie naturally took on the shoulder pole again, while Su Bai carried the basket and turned back to the camp together.
The shale flakes obtained this time were even more than those picked up after the last hailstorm.
The two of them moved four times together.
When they returned to the camp for the last time, Su Bai and the snacker were both exhausted and paralyzed.
Zhao Xinqing did not bear the burden, so she still had a lot of energy.
It was already past four o'clock in the afternoon and the sky was getting gloomy again.
Zhao Xinqing settled the foodie and Su Bai to rest in the camp, so she hurried to the fields on the south side and covered the alfalfa with the sweet potato seedlings.
As the cold wave continues for a long time, the sweet potato seedlings have already died. Although there are not many, it is foreseeable that sweet potato seedlings will be frozen to death in the next few days.
Zhao Xinqing said before that 60% of the freezing to death in five days and 80% of the freezing to death in ten days are a state where natural growth and even no covering is possible.
She covered the sweet potato field with alfalfa overnight every day, but it still had a considerable effect, and the casualty rate should drop significantly.
Zhao Xinqing sighed and went to see the paddy field seedlings again.
The seedlings were almost unaffected and even grew taller.
"It's worthy of being hybrid rice..."
"Too strong..."
Zhao Xinqing praised, and stopped delaying in the fields, and turned to the earthen kiln.
A kiln of cement was burned in the earthen kiln, and now the calcination process has been completed. Zhao Xinqing learned from Su Bai's previous operations and pulled out the cement, stomped and collected it.
Back at the camp, Su Bai, who was almost exhausted, had already stewed beef soup in the bamboo shed, while he was lying on the bed, gently rubbing the calf muscles.
Seeing this, Zhao Xinqing knew that he had walked too far with his weight today, so his leg muscles must be extremely sore.
He sat by the bed, covered Su Bai's legs with a pair of tender trousers and whispered:
"I'll help you with rubbing."
When Su Bai heard Zhao Xinqing's gentle voice, the soft part in his heart seemed to be pinched by these little hands.
