Chapter 500: Manufacturing Waterwheel 2

Lan Ze hammered a circle on the ice, expanding the ice hole a little: "The water in the deep depth is warm, the lake is definitely too small, you say I want it or not Pierce the soil above the water? "
"No, you enlarged the lake, and the area of ​​cold air that water can contact has also increased, and it may be frozen."
Bai Qingqing carefully analyzed for a while and said: "Now the water temperature below is stored in the hot season. You penetrate the ground and the temperature will dissipate. It is not known whether the water surface is frozen, but you can be sure that, The water temperature will drop. "
Lanze Maosai paused, patting his chest with fear.
"Fortunately, with you, what should I do? The surface of the water froze as soon as I slept. I didn't sleep well today, and I was awakened." Lan Ze lay on the ice, and said distressedly: "The fish are gone , It hurts me to dig in the mud, I will not starve to death. "
That would become a joke for mermaids. The mermaid is the overlord in the water, and even starved to death in the water, he will become a famous fish.
"The food is easy to solve. We have a lot of meat hanging on the tree, which is bacon for you every year."
Lan Ze said: "That's not mine."
Bai Qingqing glanced at him, "You come out with me, of course I have to guarantee your completeness. Didn't you still call me responsible?"
Lan Ze froze, looked down at the water, the clear lake reflected the beautiful face, and the light-colored lips slightly raised, so that all the females in the water could not close their legs.
Bai Qingqing pulled the dry grass from the snow and used it as a toothbrush to clean his teeth, staring at the water while thinking.
How can I keep the water from freezing?
Can't help but think of some physical knowledge, there are impurities in the water, the freezing point is lowered.
But you can't sprinkle salt all over the lake.
Lan Ze smiled and looked at Bai Qingqing, his tail waggled back and forth at random, and the water was rippled.
His eyes gradually became obsessed, and Bai Qingqing was taken back by his eyes.
Looking at the wavy water surface, and Lan Ze's swaying fish tail, Bai Qingqing moved, and his mind flashed.
Ah, you can also keep the water from freezing through exercise.
That has to let the water flow, flow, flow ...
"Waterwheel!"
Bai Qingqing suddenly shouted, Lan Ze flashed back in shock, hit the edge of the ice, "wow" broke a large piece of ice.
"What's the water?" Lan Ze asked in a daze, "What's wrong with you?"
"Hahahahaha !!!" Bai Qingqing laughed a few times, spit out the water in his mouth, quickly rinse his face and wash his face, and then said to Lanze: "I thought of a way, I will give you a surprise when I come back."
"What?" Lan Ze looked at Bai Qingqing running away, his face puzzled.
What does this ghost elf want to do? The hearts of land females are hard to guess.
"Ha ha ha ha ha ha ha ha……"
Parker far away heard Bai Qingqing's burst of laughter, couldn't help but smile, and hit a bowl of food.
It's windy outside. When Bai Qingqing runs back, the temperature of the food is just right for consumption.
Bai Qingqing stopped by the fire and hurriedly said to Parker without panting: "Parker, do me a favor."
"What's busy? Eat meat first." Parker pulled Bai Qingqing to his side and sat down, bringing the food to Bai Qingqing.
Bai Qingqing took it and put it aside, panting and saying: "Use wood to make a waterwheel that can turn, it's okay anyway, let's try it."
The original purpose was to help Lan Ze, but after thinking of the waterwheel, Bai Qingqing's interest was raised.
