I'm used to planning before doing things, from simple to difficult, so that each one breaks down, and the organization is clear.

Yunwen and I have several main tasks, one is to open the water wheel channel and clean the sludge on the channel, which is more conducive to getting water, and it will be more convenient to water the farmland, and the other is to prepare to go to the cellar to investigate, the two are easy to say, it should be the former, after all, exploring the cellar is relatively risky, and the former is slightly easier to start.

So, I asked Yun Wen to take care of Sanfu first, feed enough forage and water, and I groped for the situation of the waterwheel and the various parts of the canal, and went to the backyard of the back door to see the spring pool and the waterwheel, only to see the spring water gushing from the mountain wall to form a small waterfall and continue to pour in the aqueduct of the waterwheel, which should have fallen because of gravity, but the spring water filled two or three aqueducts, and the water overflowed, and the waterwheel did not move.

I was a little curious, treading the water and looking closely, but I found that there was a large wooden gear in front of the third and second aqueducts closest to the water where the waterwheel was running, and a log pole was connected to the middle of the gear in the form of mortise and tenon.

I couldn't help but smile wryly, is this a joke?

At the end of the log pole there is still a gear connected to the end of the pole, and this vertical gear is connected to a transverse gear at the same time, and the teeth are attached to each other, and the transverse gear stands near the channel, but it is a rotating shaft, and the rotating shaft gear is stuck by an iron rod, which leaves some distance between the front and back, and I expect that it is used to move the switch back and forth.

So, I moved the iron rod back, and sure enough, the channel went down, and at the same time the interlocking gears immediately opened, and began to turn each other, and then I looked at the other end, and the waterwheel also turned, and the stuck part was opened, and the waterwheel was not limited by the gears, and it was able to turn as the water filled the aqueduct, and when the water of the aqueduct descended from the rotating waterwheel, it also began to flow into the aqueduct, and the aqueduct began to flow and flowed down.

Hearing this voice, Yingchun immediately ran out, and screamed wow!

"This waterwheel is connected to a gear bearing, and the designer is probably a master mechanic, right?" Yingchun said admiringly.

I have only heard that she hurts people, and it is the first person to praise people who admire her so much.

Being able to use some kind of mechanical principle to switch this waterwheel at will, this designer does have some talent, and I also think about it.

The water flowing down the canal is watered down, and soon it flows into the land to form puddles, which if the field has been ploughed and sown, and there are enough soil and water channels in the field, only need to open and close, do not need to care, this watering operation may be completed.

After that, I pulled the iron pestle switch on the block, and the channel went up slightly, and the waterwheel also stopped, Yunwen and I cleaned the aqueduct together, and used stones to remove the mold on the wooden board, scraped hard, and also went to the waterwheel to clean it up, an aqueduct and an aqueduct, and let Yunwen sit on my neck to clean it up.

Since the homework is all related to water, after doing this, both of us are soaked, and Yun Wen because of this, the clothes on her body are soaked, and her excellent and slender figure is looming prominent, and her wet hair is occasionally thrown up, full of a certain degree of charm, I coughed, it is really not good to take advantage of this, and hurriedly withdrew my gaze.

Yun Wen covered her mouth and smiled, not too minding my rudeness.

After these tasks, the waterwheel is done, and there will be no problems in fetching water, irrigating fields, washing dishes and vegetables, bathing horses, etc., this function is better than the faucet, not to mention that this is mountain spring water, is it not purer than pool water?

With that done, the first task was successfully completed, and the second, which was more important to me, was the cellar that I had found last night, and I had marked it and probably remembered the route, so the two of them set out with the sapper shovel.

Along the vicinity of the place where I relieved my hands last night, I specially smelled it myself, and I was glad that there was no smell left, otherwise Yunwen would not be embarrassed to smell me?

Walking to the left part of the yard, there were still a lot of wild wheat poles left, and there were wild ears of wheat on them, and these poles and ears were useful, so I kept them for a while, and went all the way to the most remote fence on the left, and I saw the notch on the wooden board of the fence, and the stone was still standing there, so I was sure that it was in this vicinity.

Digging the earth, about 20 centimeters deep, sure enough, I saw a wooden board blocking the entrance, and the excavated soil around it was removed so as not to fall into the cellar.

"I'll go find a torch." Yun Wen said.

"Okay, take two big ones and one small one." I said.

"Hmm."

So Yun Wen went to the wooden house to get the torch, as I ordered, two big and one small burning twigs, I first helped Yun Wen to a farther place, threw the burning twigs into the cellar, and observed its changes, if it detonated, it means that there is more methane in the air, if it is extinguished immediately, it means that there is more carbon dioxide, which is not conducive to people going down, and it is extremely easy to cause people to faint due to lack of oxygen in it.

However, the burning of the small dry branches in the cave did not cause an explosion or extinguish immediately, but was in a trance, and then swayed for a moment, which surprised me deeply, but since the fire would not be extinguished immediately, it meant that the oxygen content in the air was sufficient, and there would be no danger in going on.

But just in case, I still took the torch and went down first, but before I went down, I tied a rope around my waist, so that if I was in danger, Yun Wen could call the other girls to pull me out of the cellar as soon as possible.

After some preparation, I took the torch and went down, there is a wooden ladder on the way down, I went down without hindrance, about 20 steps, I went to the ground of the cellar, roughly calculated, the first step is about 25~30cm, that is to say, the bottom is about five or six meters high from the ground, digging so deep?

Then I was even more surprised when I felt a chill and my clothes were wrinkled, indicating that there was wind underground!

"This is the cellar? But don't be a wormhole, you want to scare people to death. "I can't help but wonder.

However, I soon dispelled my doubts, because there was a light not far ahead, and the fire had not been extinguished for a long time, and I had been listening to the wall for a long time, and my ears were sensitive, and if there was anything in the wall, it would never escape my ears, and if there was anything in front of me, I could hear the sound of the ground stepping on the ground as I listened to the wall, even if it was faint.

But there was nothing, the only thing I could hear was the strange sound of the wind, not only could I stay down, but the air was so good that I could smell a little fragrance.

Looks like it's fine.

"Yunwen, come down, be careful." I said.

"Okay." Yun Wen replied from above.

Soon she also came down, and when she reached the last step, she almost stepped on the air, and I hurried over to help her, and she lay in my arms at once, and my hand also touched her thin willow waist, and both of them turned red, and I even had a feeling of getting my wish, which was really a little obscene to say.

"How long are you going to hold it, and still get down to business?" Yun Wenjiao asked.

I coughed, let go, and said, "I'm sorry, of course." ”

She smiled, then walked past me, sniffed, and exclaimed, "It's so fragrant here, it seems to be the smell of incense used by the ancients, a kind of incense called dragon birthday incense." ”
