Who knows! As soon as I returned to the mountains to farm, I encountered a natural disaster.

After closing the pig pen door, Zhao Yeqing put down the ladle in his hand and went to the door to take a look.

Mu Xi put the noose in his hand around the neck of a mixed-breed sheep and pulled it home, but the sheep struggled back desperately.

Several other mixed-breed sheep that had been relatively quiet began to move.

The other two dogs who were looking after the little pig at home saw this and rushed forward to help. The four dogs and Mu Xi's leash finally allowed him to walk back honestly.

Zhao Yeqing couldn't help but click his tongue, there was something wild in this bloodline.

The last wave of pasture harvest at home has been finished, and the old seedlings in the fields can no longer hope to continue growing and wait for the next harvest.

Generally, the yield of grass sown at once will drop sharply after three harvests, and the soil must be plowed and sown again.

Considering that if this mixed-breed sheep is still so wild, it can only be kept at home and fed for a period of time to soften its temperament.

Keeping them in a cage consumes more feed, but if the goats are kept in a cage all the time, they will easily get sick. They need to be let out for air every few days. The remaining silage is enough to feed these sheep.

Mu Xi's already sore arms became even worse after pulling the sheep. During dinner, the hand holding the chopsticks almost became Parkinson's disease.

Zhao Yeqing's eyes looked a little pitiful.

Zhao Yeqing couldn't help but want to laugh: "Why? Do you want me to feed you?"

Mu Xi stood up and went to get a spoon to eat. There was no embarrassment on his face, but his ears were red for ten minutes before they subsided.

Even when Zhao Yeqing saw it, he didn't relent. Who asked him to show off and move two barrels of oil? If he shows off at this time, he may lose his life at any time.

Just let him have a long memory.

But if you have to rub the medicinal wine, you should rub it for ten minutes when you wake up in the morning, and rub it for a while before going to bed at night to loosen the tight muscles.

After getting up again, Mu Xi's hand was finally mostly healed, and he immediately volunteered to dig grass roots in the ground to prepare for sowing grass.

Zhao Yeqing still had to study her pulley set, so he waved his hand and let Mu Xi go.

You can't just do nothing if your muscles are sore, otherwise the pain will be worse and recovery will be slower.

There are still ten centimeters of grass roots on the ground. It doesn't take much effort. You just need to bend down and pull out the top part and throw it away.

As soon as Mu Xi pulled out two grasses, he saw a round little mushroom, which was pressed under a handful of weeds thrown away when cutting the pasture.

When I picked it off, I saw that it was indeed a straw mushroom.

This mushroom likes to grow under haystacks. The high temperature environment of wet haystacks after rain is a paradise for this kind of straw mushroom.

If there is one here, there is definitely one in the fields.

After this year's wheat harvest was threshed, the hay house was almost filled with straw and hay. A lot of the remaining wheat straw was wet by the rain and was too lazy to be dried and was thrown into the field.

Mu Xi casually threw aside the grass roots in his hand, then walked to the straws and opened them...

Sure enough, a large area grew, with seven or eight small straw mushrooms growing in a palm-sized area.

Mu Xi didn't care about pulling weeds anymore and picked all the straw mushrooms at the bottom and carried them home in his clothes.

Zhao Yeqing saw that Mu Xi had only been out for ten minutes and had returned. When he was about to ask, he saw a bag of straw mushrooms in his arms.

He couldn't help but chuckle: "It seems that we have chicken stewed with straw mushrooms tonight." It happened that there were more and more chickens in the chicken coop recently, and the two of them had no time to collect the eggs, and the chickens were popping out in nests.

Just as he finished speaking, the ducks lined up to go out for a bath again. After counting, there were only nine ducks.

The last female duck laid eggs some time ago and has been incubating them in the nest and rarely comes out to play in the water.

In order for domestic ducks to keep laying eggs, the work of incubating eggs is usually done by hens or manually. Only a small number of rural ducks and wild ducks still retain the habit of mother ducks holding nests.

It seems that in more than ten days at home, another group of squealing little things will break out of their shells.

After the little episode, Mu Xi put the straw mushrooms in the kitchen and went out to pull weeds again. Only Zhao Yeqing was left in the yard polishing a pile of wooden parts.

July 3040

Zhao Yeqing also didn't expect that the small parts that he thought were simple would take so long to make. The result of his lack of carpentry experience was constant rework. It was useless to rework the parts that didn't fit well. He had to re-take the materials and start again.

Mu Xi wanted to help, but Zhao Yeqing refused. At the beginning, he was indeed bald, but after doing carpentry for a long time, he became more and more addicted.

The carving knife carved little by little and the sandpaper polished little by little. The originally impatient heart slowly calmed down.

After completing the pulley set, they had to experiment with which method was the most labor-saving. Both of them searched for memories in their brains. After trying several combinations, they found that the combination of the pull-up directional pulley and the directional pulley was the most labor-saving.

When only one pulley is used, the required pulling force is the same as the weight of the gasoline barrel. Using two pulleys, one moving and one stationary, to pull the rope at the same time, and the rope is pulled up and down, the required force can be saved in half.

When using two pulleys and the rope is pulled from bottom to top, the force required is only one-third of the original.

Pull down on the left and pull up on the right

......

Forgotten physics knowledge always comes back to her mind in various ways.

The final step only requires fixing the mounting bracket of the directional pulley on the edge of the cliff.

The expansion rivets that Mu Xi had drilled on the cliff before were made with a small portable electric drill, which was also in the climbing bag. There were also large rocks on the side of the cliff. The idea of ​​the two of them was to drill holes in the rocks and expand the brackets. Rivets hold the cliff together.

After the other movable pulley is connected to the rope, it is hung with the gasoline barrel underneath. When the rope is pulled, the two pulleys move at the same time, so that the gasoline can be lifted steadily from the bottom of the mountain.

The pulled rope is combined with the runner made before, so that the rope can be organized while pulling the rope, and it can also play a fixed role to prevent the rope from being loose and the gasoline barrel accidentally falling. Fall.

Zhao Yeqing polished the pulley set very smoothly. After all, the force that the pulley set could save did not include friction. To save enough effort, the wheel had to be smooth enough.

The weight of the wheel and the weight of the rope are also factors to consider, but the requirements cannot be too high now. Zhao Yeqing has already exhausted his talent in making such a device.

I used to be distracted in class, but now I regret it whenever I think of her.

The importance of compulsory education is completely closed at this time.

I wish I could find two more physics books and study them every day. If I had studied hard, my agricultural facilities might have entered the field of automation long ago. There are so many parts, metals and car engines in tourist areas... .

If a physics guru were here, he would have already modified a lot of agricultural machinery.

Mu Xi specially went to get the beehive back today. As soon as he walked in, he saw Zhao Yeqing with a sigh on his face. After asking, he found out what she was thinking. He handed her a large bucket of honeycomb honey and said:

"Okay, what are you thinking about? A physics master might not be able to tell the difference between onions and garlic. He might starve to death if he can't grow food."
