Yan Jing'an asked, "If there is geothermal energy, can crops be harvested twice a year?"

But this doesn't look like it at all; the plain is covered with withered grass, not a single patch of green.

Yan Zheng said, "I'm afraid it's not that ideal. The surrounding mountains are high, and this plain is right in the middle. The water that flows down from the mountains on both sides, including the water that flows down from the mountain where the stone house is located, will eventually all converge here. In winter and spring, this field will be submerged in water for nearly three months."

This explains why these plants withered and turned yellow even with geothermal heat; they had all died from waterlogging.

Jiang Xi was actually very satisfied with this place. Putting aside everything else, the fact that it had geothermal energy was already quite rare.

If there is an opportunity in the future, we can build water conservancy projects to guide and dredge the snowmelt from the mountains, which will eventually create a dry place.

Even though it's so cold now, she feels that the temperature here is still a few degrees higher than outside. When she builds a house here, she can use the geothermal energy to create a natural bathroom, which will solve the problem of taking a bath in winter.

The only regret is the lack of glass or plastic, which would have allowed for the construction of a greenhouse in winter, ensuring an abundance of vegetables and fruits.

Unfortunately, she could only dream about it, she consoled herself.

Yan Zheng, who was standing to the side, felt that it was about time and turned around and said, "Let's go, it's already late afternoon. Let's go back and repair that stone house. Since we're going to move, let's prepare in advance. Let's tidy up these rooms in the next couple of days, so that we don't end up in a mess when we move over."

Yan Jing'an, however, had a different opinion.

He had witnessed a real flash flood. Melted snow doesn't flow down little by little; it accumulates until the original riverbed can't withstand the pressure and suddenly bursts its banks. In other words, natural disasters don't give humans time to react.

He said in a deep voice, “I know what you said makes sense, but you won’t know unless you’ve experienced it. When a flash flood really breaks out, it’s not like you think, where the water level rises by one centimeter today and two centimeters tomorrow. It can completely submerge a mountain or a city within ten minutes. We need to move as soon as possible, preferably before the next wave of warmer weather.”

His words were serious and earnest. Jiang Xi and Yan Zheng exchanged a glance.

Yan Zheng knew in his heart that what he said made sense. Although he had never seen such a scene before, for the safety of everyone, some dangers could not be taken.

He thought for two more seconds and said, "Okay, let's do it your way. We'll start moving things tomorrow. For safety's sake, after we finish moving one batch tomorrow, we'll all sleep in the kiln house tonight, instead of in the cave."

"I'll rush back tonight to pack my things. The supplies that will be transported from there tomorrow morning will all be put in the first house in the northwest corner."

Jiang Xi said, "I estimate the move will take several days."

As Yan Zheng walked, he said, "I estimate it will take four or five days. Tomorrow morning, we'll move the dried goods over and seal all the windows in the northwest corner of the house to prevent other animals from going in and ruining our food."

Jiang Xi suddenly thought of the wooden cart outside the pottery kiln: "Do you still remember that cart in the yard? I wonder if it's still usable. Wouldn't it make things twice as easy for us?"

After hearing what she said, Yan Zheng also remembered: "You're the one who's really sharp."

Yan Jing'an had no objection to this decision, so the three of them returned to the abandoned village.

After leaving the mountains and returning to the courtyard of the ceramic house, Yan Zheng casually picked a handful of grass and cleared the snow off the wooden cart.

The design of the cart is very simple. There are two wheels on each side and a bearing in the middle. The body is made of sturdy wooden planks, about 1.2 to 1.3 meters wide and about 2 meters long. There is no carriage, only a crossbeam about ten centimeters wide on both sides as a handrail.

Yan Zheng and Yan Jing'an checked it inside and out.

Yan Jing'an clicked his tongue and said, "I didn't expect it to be made of ironwood. They actually managed to find this kind of wood in the mountains."

"Iron nanmu?"

This was the first time Jiang Xi had heard of this kind of wood; perhaps it was unique to this world.

Yan Jing'an explained, "This kind of wood is not only particularly hard, but also not easy to rot. In the past, people of high status liked to use it to make coffins to prevent moisture and insects."

Jiang Xi understood as soon as he said that.

This is just like the rosewood from the original world.

The difference is that, in the evolution of the two worlds, they may have become two completely different species due to some minor genetic errors.

Yan Zheng pulled the wooden cart out, walked it around the yard a couple of times to test it, and said, "The right wheel is a bit deformed."

"etc."

As she spoke, Jiang Xi lay down on the ground and glanced at the bearings under the car.

She then said, "I guessed right, there's a crack in the bearing. I've seen carriages like this before, and the bearings are the most common problem with these carriages."

Jiang Xi breathed on her reddened hands and said, "We can't move like this. If there's even a slight bump on the road, or if it's subjected to any force, this car will be ruined."

Yan Zheng thought for a moment and said, "I'm looking for a crossbeam to fix this broken one first, increasing its load-bearing surface. That should be feasible."

After listening, Jiang Xi thought it was feasible: "We can give it a try."

This ordeal took another two hours, and the car's bearings were given a second layer of protection.

When I set off home, the sun had already completely set in the west.

Yan Zheng and Yan Jing'an pulled the carriage from the front, while Jiang Xi pushed from behind. Actually, she didn't need to exert too much effort, as the two men in front were putting in their best effort, and neither of them wanted to appear physically weak.

Jiang Xi only needs to help lift the back of the car a couple of times when they encounter some difficult roads.

By the time we arrived at the cave, it was completely dark.

Under the moonlight, the ice at the entrance of the cave looked even thicker.

Yan Jing'an pulled the cart with difficulty and said, "It was like this at the beginning. The snow melted during the day and froze into thick ice at night. If the temperature suddenly rises one day, the dam will burst and the foot of the mountain will become a vast ocean."

The road from the foot of the mountain to the cave is usually manageable, but with a car, the difficulty increases dramatically. It took three people a lot of effort to push it up only a few meters.

Sweating profusely, Jiang Xi thought to herself, "Why make things difficult for myself?"

She simply gave up, waving her hand breathlessly, "I'm not pushing it anymore. I'll just leave it at the foot of the mountain. I can always make a few more trips tomorrow."

She had originally planned to push it to the doorway so that it would be easier to load things up tomorrow, but now she fears her back will be ruined before she even gets up there.

That made sense. Yan Zheng and Yan Jing'an were also exhausted and covered in sweat, so they decided to take her advice.

But we can't just leave the car here unattended.

"A rope." Yan Zheng reached out his hand.

Yan Jing'an quickly covered his waist. "What are you doing?"
