Tatsu is an upgraded version of the 碓臼.

The initial stepping stone is still a stone coffin, with a large stone chiseled into a nest, the huge nest generally requires four people to lift it, the body of the nest must be buried in the ground, the mouth of the mortar exposed to the ground.

On the top of the nest, there is a "body" made of thick tree segments.

Move the center of gravity to the tail of the "Tsui" and press it down into the pit, the head of the "Tsui" is raised, and then the head is lifted, and then the head is lifted, and then it is lifted up, and the spoon is repeated, which is the rice.

Such a stone is heavy and clumsy, and it cannot be operated by a non-sturdy man.

With the development of the times, the tampling slowly threw away the bulky stone and switched to solid wood.

At the bottom is a long piece of wood, with a pit at one end, in which the grain to be processed is placed, and a hammer is mounted on one end of the long wooden arm, and the other end is trampled to make the hammer pound the grain and remove the husk.

Liu Qingyue intends to directly promote the stepping of solid wood.

She drew a sketch, carefully marked the dimensions and precautions in all aspects, and then handed it to Gu Wen.

After Gu Wen ate the sketch thoroughly, he gave Liu Qingyue a thumbs up in shock and admiration, and then went out with the sketch.

It does not need to use iron, and the cost is low and it is easy to promote.

After Xu Xiuyun saw the sketch of the stepping mill, he immediately arranged for someone to recruit carpenters, found a large number of suitable wood, and rushed to make a batch of stepping mills in large quantities and distributed them to various towns in Yongning Mansion.

Liu Qingyue looked at the stepping stone that was distributed to Nanshan Village, and was particularly disturbed.

There is a black technology, but it can't be used, this feeling is simply not too bad.

The only thing that comforted her was the character value of Drunken Lotus, and once again got a qualitative leap, from 502,380 points to 802,380 points, and the one million points that Drunken Lotus had recited many times was only 200,000 points.

What once seemed unattainable has been achieved in just a few months.

Such a leap made Liu Qingyue's heart can't help but wonder if the value of the billions of people mentioned by Drunken Lotus will also be realized one day.

The willow light moon fluttered.

Drunken Lotus unceremoniously poured cold water: [Master, there is a limit to daydreaming. 】

Liu Qingyue......

She decided that when her character value reaches nine nines, she will no longer do good deeds, but directly change to doing evil, so that Drunken Lotus's character value will never reach one billion, so that it will always be manipulated!

！！！

Drunken Lotus swiped the exclamation mark to express her feelings, and then immediately turned into a dog's leg.

[Master, master, I was wrong, you are so powerful, the value of a billion people is only a minute, I believe that the master will be able to kill all sides and benefit the world. 】

Liu Qingyue was speechless for a moment, and threw the word Drunken Lotus to it.

[Shut up!] 】

This ability to organize words really made Liu Qingyue can't help but doubt the professionalism of Drunken Lotus.

Fortunately, the information in the database is not its organizational language, otherwise it would have become a book of heaven.

The stepping stone was sent to Nanshan Village, which once again caused the shock of Nanshan Village, and everyone watched around a few stepping stones, you touch it, I touch it, and I can't stop praising Liu Qingyue's intelligence.

Liu Qingyue took this opportunity to mention that she would plant new varieties of plants on a large scale next year.

Not only peppers, but also corn, potatoes.

These are all seeds that Ling Zijin helped her retrieve, and she plans to pilot it in Nanshan Village, and then slowly promote the planting, and finally radiate to the entire Dayin Dynasty.

and even more distant countries.

When the time comes, the crops will be harvested and there will be more varieties of grain, and the peasants at the bottom will have a better life.
