Qiao Xuejun: "Have you ever participated in manually digging a well?"

Qiao Xuejun knew how to dig a well, but she only knew some theoretical knowledge and had never actually done it, so she had little confidence.

Kuang Qianli asked her: "Can you fight?"

Qiao Xuejun shook her head: "I haven't done it before, but I have learned how to use a hand crank to pump water into a well."

From a theoretical point of view, all you need to do is dig to find groundwater, and then use a hand crank to pump the well water out from underground.

Thinking of this, Qiao Xuejun immediately said, "Little Carpenter, do you still have some bamboo tubes left from last time? The large ones?"

The young carpenter nodded: "There are more."

"You can make a hand-cranked well digger."

The carpenter: "Isn't that sold in the store?"

Qiao Xuejun said, "You can make it with bamboo tubes and wood. After all, it doesn't require electricity. The structure is delicate but not complicated. People in the past also made it with wood. I'll draw a structural diagram later. See if you can replicate it based on the diagram."

Qiao Xuejun returned to the living room, picked up paper and pen, and started painting.

Her drawings are not particularly professional or beautiful, the straight lines are not straight and the circles are not round, but they are very clear, and there are three views with all the dimensions marked.

Qiao Xuejun drew a hand-cranked water pump that he had seen in a book on the evolution of farmers' wells. The carpenter looked at it for a while and asked a few more questions: "Is this one-way and made of wood chips?"

"You can push down here, right?"

"Okay, I understand."

The young carpenter flicked the paper in his hand and said, "I can do it. No problem."

Qiao Xuejun nodded: "Let's go to the potato field and dig a well there. You will be responsible for doing this. When the time comes, we can install it and use it directly, understand?"

The carpenter said: "Just leave it to me."

Qiao Xuejun took out some tools from the warehouse, as well as a hoe, shovel and bucket bought from the farm tool store.

She handed the hoe to Kuang Qianli: "Go dig."

Kuang Qianli was shocked: "Really digging? Manually?"

Qiao Xuejun thrust the hoe into his hands and said, "Why are you panicking? You'll only need to dig one meter to find water. It won't take much effort on your part."

When she first moved in, the system told her that there was water underneath, so the shelter couldn't be built any deeper. It was also told to be less than one meter.

She handed the bucket and shovel to Wang Juanfeng: "You take away the soil he dug out."

Wang Juanfeng took it: "Okay."

"I'll go outside and pick up some stones to tamp the well wall." Qiao Xuejun turned around and went upstairs. "There are stones in the yard outside. I won't go far."

She went to find stones and move the system down, and while they were busy over there, she could also move the medicine cabinet down.
