Mu Ruxue explained the principles of modern earthen kangs. "If the soil where people sleep is too thin, it will definitely collapse. So when I look at other people's earthen kangs, they all have pillars, but they allow heat to circulate inside. The closer to the fire, the warmer it is, and the further inward, the lower the temperature."
Yun Ruoxi's eyes lit up instantly after clicking on it. "Yeah, why didn't you think of this method? As long as there are support points everywhere, it will be fine. After all, stone is harder than soil. As long as our idea works, the heat resistance function will be much better than the earthen kang."
Mu Ruxue held her forehead helplessly. "Xixi, are you kidding me? This is stone. How could you hollow it out so easily? These principles must have been thought of by others before, so why haven't they been widely adopted? It must be because they are difficult to operate."
Yun Ruoxi naturally knew that it was not easy to operate, but there were weapons from the world of immortal cultivation in the space. She moved her mind and a dagger appeared in her hand.
This is a magical weapon from space. It should be much sharper than ordinary weapons, but how much sharper it is still needs to be tested.
Thinking of this, Yun Ruoxi, under the gaze of Mu Ruxue, used a dagger to dig a hole in the side of the stone bed.
Mu Ruxue watched Yun Ruoxi scratching the stone bed with a dagger as if she was cutting tofu, and her mouth was wide open in surprise.
At this time, everyone present stopped what they were doing and gathered around Yun Ruoxi, watching her movements.
Everyone looked at Yun Ruoxi's movements and knew that this was the treasure given to her by her master.
Xiao Jingrui had never thought about the things in the world of immortal cultivation. Cutting stone was as effortless as cutting tofu. However, cutting stone was rough work after all.
So Xiao Jingrui stepped forward and took the dagger from Yun Ruoxi's hand, saying softly, "Let me take care of these things. Don't get your clothes dirty."
Yun Ruoxi, who originally wanted to do it herself, could only helplessly hand the dagger to Xiao Jingrui.
"Okay, then you can do it. This dagger is a magical weapon and is very sharp. Be careful when you use it."
Xiao Jingrui nodded and continued digging the kang.
They all knew the principle of the kang, so it was not difficult to dig. So, Xiao Jingrui kept digging, and Xiao Jingxuan helped to move out the rubble inside.
Yun Ruoxi saw Xiao Jingxuan preparing to move the stones with his bare hands and hurriedly stopped him, "Jingxuan, I'll put these stones in a storage ring separately. We can use them when we build a house in Lingnan."
Because no one knows what the situation in Lingnan is like, it is not clear whether the materials needed to build a house are easy to buy.
Therefore, it is reasonable for Yun Ruoxi to want to stockpile materials now.
But which good person would use the treasures of immortals to pack stones?
Only Yun Ruoxi was wealthy enough to take out a storage ring to store the stones.
Zhao smiled and said, "Xixi is right. We don't know what the situation will be like when we get to Lingnan. If building materials are hard to buy, we'll have to go up the mountain to find them ourselves. It's good to collect them now. At least it can save some money, right?"
Zhao and Xiao Jing were lighting the stove while chatting with everyone with a smile.
Mu Ruxue took out a modern double bed from the space ring, and it was furnished with a modern coral fleece four-piece set.
Because my grandmother had a fever, we went from the foot of the mountain to the middle of the mountain, and now to the cave at the top of the mountain. My grandmother followed us through all the trouble, and now it seems that she has a fever again.
Mu Ruxue took out her own bed and let her grandmother rest in it early.
Since the entire cave is now occupied by their people, Mu Ruxue no longer has so many concerns and found wire and nails in the space.
I hammered iron nails into the cave walls and then surrounded my grandmother's bed with sheets.
However, this fabric was purchased in the Daye Dynasty. The fabric is gray-blue and can block some light.
Madam Xiao looked at the bed that Mu Ruxue brought out and liked it very much. "This bed is really beautiful. Wouldn't it be a waste for an old woman like me to sleep on it?"
Mu Ruxue: "Grandma, what are you talking about? You are the head of the family, and now you have caught a cold. The cave has not been prepared yet, and Grandma can't wait forever. You need to rest well before anything else. Don't worry, we are here, and we will definitely prepare everything."
Old Madam Xiao took Mu Ruxue's hand and said with a look of satisfaction: "You two granddaughters-in-law have married the right people. Grandmother thanks you on behalf of the entire Xiao family."
Mu Ruxue: "Grandma, please don't be polite. We are all family, so let's not talk nonsense. Besides, you and mother-in-law really treat us well. Xixi and I know it."
With that, Mu Ruxue helped her grandmother to bed to rest. It was the first time for Old Madam Xiao to sleep on such a soft bed, and she was a little uncomfortable for a while.
As soon as I sat on the mattress, I felt a rebound force. "This bed is too soft. It's like sleeping on cotton."
In fact, it is not suitable for the elderly to sleep on mattresses that are too soft, so the mattress that Mu Ruxue took out had only 3 or 4 cm thick latex, which was not too soft and was just right for the elderly to sleep on.
But where had such a mattress been seen in the Daye Dynasty? So when my grandmother slept on it, she found it exceptionally soft.
Mu Ruxue covered her grandmother with a quilt, and Mrs. Xiao's hands kept stroking the short fluff on the quilt.
"This fabric is good too. It's very comfortable to sleep on."
Mu Ruxue explained with a smile, "This is coral fleece. It's very warm, and the longer you sleep, the warmer it gets. Grandma has a fever right now, so she must not catch a cold again."
There are now three stoves burning in the cave at the same time, and the temperature has risen.
Even though the entire cave is very large, about 500 square meters, these people will not feel crowded living in it.
Yun Ruoxi planned the entire cave. The boys' resting place was in the cave, at 1 o'clock outside, and Lu Juan slept inside the cave.
Because the cave door is not blocked very tightly and there is still some ventilation, there is no need to worry about carbon monoxide poisoning from burning the stove in the cave.
Everyone was making a fire, boiling ginger soup, while Yun Ruoyang took his four younger brothers to check out another cave.
There are many caves of different sizes on the top of the mountain. This cave is not the largest, but it is not small either. There is a smaller cave connected to the right, but it is also 100 square meters.
Yun Ruoyang left all their horses in the cave next door. He originally wanted to go out to collect some firewood, but the rain was too heavy and all the wood was wet. He could not use it, so he had no choice but to return to the cave.
