"Third brother, let's go and bake the fire." She didn't rush to ask him about the water hole, but used her sleeve to quickly wipe the water stains on him.

"Daughter-in-law...... You rub my sleeve on me...... Your sleeves are wet. He frowned.

"It's okay, bake it and it's dry." She hurried to get his clothes.

He had been naked for so long, if ordinary people had frozen.

The third brother said that he often took cold showers in winter, and sometimes went down to the river to take a bath on cold days. Therefore, the cold resistance of the waterholes in the world is better than that of ordinary people.

He hurriedly put on his clothes and sat down by the fire to make a fire.

Su Qingyue sat next to him, her little hands constantly rubbing the backs of his palms.

He felt the warmth of her palm, and his frozen heart seemed to be warm, and he said distressedly, "Daughter-in-law, my hands are cold, don't touch me, it's not good if you get cold." ”

She shook her head, still rubbing his hands quickly, and didn't ask about the situation in the cliff cave in the waterhole, because the third brother was chattering with his teeth when he spoke.

He took the initiative to say, "I swam into the cave, which was large enough to fit the width of a tiger, and then narrowed so that it could only be swam through by one person, so that the tiger carcass would get stuck. I swam slowly forward, the cave was very deep, it was dressed at the bottom of the cliff, and the water in the pool filled the cave and flowed all the way to the outside. Just about a meter away from the exit of the cave, it suddenly became narrower, and people couldn't pass through it at all. Even if you are sideways, it is only half a person who has passed through the seam. I couldn't turn around when I swam back, I was lying on the cave wall and retreating, and I didn't turn around and swim back until I was a little more spacious. ”

Su Qingyue was silent, "It's so close to leaving the waterhole, but there is only one seam that can't get out, it's really ......"

Depressed.

"Daughter-in-law, this must be the only exit to the outside." Xiao Yuchuan said, "I have to dive down again and chisel the one-meter narrow slit wide." ”

Looking at the snow that was still falling, "This snow is also falling intermittently, the weather is getting colder and colder, in a few days, the pool water should freeze, if it freezes, we can't get out of the water, we can't get out before the snow melts in spring." ”

Su Qingyue also looked at the icy weather, "It's not more than five days, it's definitely frozen." Third brother, within five days, we will chisel and widen that seam. ”

Although it is only necessary to chisel a distance of one meter, it is underwater, a long cave, which is full of water, which consumes all the breath that people can hold, and it is good to be able to swim to that one meter, where does the excess breath come from to chisel the wall stone?

What's more, so icy water.

Xiao Yuchuan's face was a little embarrassed, "When you reach the narrow slit, save your breath and swim back, it's already held to the limit, you can't change your breath, you have to swim back soon, you can't save gas to chisel the wall, you want to widen the one-meter seam for people to pass through, at least one tool, every time you enter the water, you can change at least three breaths, otherwise, it's impossible in five days." ”

Both of them were worried, in the cave wall of the waterhole, a cave wall was full of water, what to exchange for air?

In ancient times, there was no diving equipment, and there were smart people who used reed stalks to ventilate, but the problem is that there are no reed stalks here, and the cave is more than two meters underwater, and there are no reed stalks that long.

The two were silent.

The wind was chilling.

Su Qingyue added two sticks of firewood into the fire and turned the fire hotter.
