Only ghosts need to study!

Even though we are playing with excrement, it is still play, right?

Seeing Yang Xiu and Cao Pi happily playing with shit together, He Yan felt even more pleased.

"The new school has you~then I'll feel relieved!"

Ren Jun also came over and asked quietly: "Yulang, is this... really useful?"

"It will definitely work! Uncle can make more manure. I can't say that next year's harvest can be increased by 50%, but there is absolutely no problem if it grows by at least 20 to 30%."

"And with the availability of manure, crop rotation can naturally be implemented to increase production."

The method of crop rotation refers to planting crops in one field in turn within a year.

For example, you can plant millet first, then plant beetroot after the millet is harvested, and then plant millet after the beetroot is harvested...

Because of the problem of soil fertility, even though the method of crop rotation has been implemented as early as the Western Han Dynasty, it is not easy to implement it in a field for a long time, lest the land loses its fertility and becomes poor farmland.

But if you have this manure, you don't need to worry about excessive depletion of land fertility, and you can practice crop rotation with confidence and boldness.

Ren Jun's eyes lit up after hearing the advice given by He Yan: "If it is true as Yulang said, I am afraid that next year's grain output will double!"

"That's not necessarily the case, but growth is definitely certain."

With more food, the people's lives will be better, and Cao Cao's power will be stronger.

For example, in the Battle of Guandu this time, if Yuan Shao brought hundreds of thousands of stones of food from Wuyang to Wuyang after Cao Cao burned down Wuchao, then even a god descending to earth would be unable to do anything about it.

And similarly, if Cao Cao's power is stronger, the duration of this troubled times will be shorter.

"The rise of this new learning has never been the deceptive solar eclipse."

“It’s about the countless amounts of food that will grow from the ground in the future!”

He Yan looked back and looked at the busy Yang Xiu, Cao Pi, and the numerous soldiers stationed in the fields.

“The beginning of a new study is not in the room at Hua Xin’s house, not in the New Interpretation of Zhouyi, or in Mencius, but here!”

From then on, the roots of the new learning... were truly rooted in this soil, and began to brave the storm and stubbornly declare war on this world!

While He Yan was planning the future of Xinxue, Yang Xiu and Cao Pi had already built a hollow mound.

Although Yang Xiu was full of stench, he was very happy: "The new learning is really amazing! The unity of knowledge and action! What a unity of knowledge and action! In this way, when the harvest next year, everything will be clear!"

Cao Pi was very happy at first, but when he saw He Yan with empty hands and the field soldiers who were building earth furnaces around him, he still asked something that puzzled him -

"Mr. Yang, even if we don't do it, wouldn't the soldiers around us be able to make earthen stoves?"

Yang Xiu: "..."

Damn! It makes so much sense!

I didn’t expect that???
