In Qingshui Village, there are more than 80 households, and each household can only receive a maximum of ten jin of grain.

Moreover, this amount of ten jin is calculated based on the highest extraction rate. Without the support of modern technology, the extraction rate might be cut in half to five percent, meaning a family might only receive five jin of grain.

She could buy more grain than a pound of wild vegetables by digging them up in the mountains.

Wan Shu was not interested in this, but the villagers, who were unaware of the truth, were immediately abuzz with excitement upon hearing it.

"My God! Tens of thousands of pounds! Our family can get at least a hundred pounds!"

"With over a hundred kilograms of grain, our entire village will be able to survive until the autumn harvest!"

Some villagers couldn't wait.

"Village head, Yaozu! You two are amazing! Please tell us the extraction method from the ancient book as soon as possible! We will be eternally grateful to you!"

Aunt Wu, who had been poisoned by potato leaves last night, happened to be standing next to Wan Shu with her two grandsons.

Wan Shu heard her pleading loudly, "Village head, please, please tell us how to extract fern powder! Please, have mercy and save our lives!"

Aunt Wu shouted loudly, and the other villagers also shouted loudly, but Li Dagen seemed not to hear them at all.

He only spoke slowly after a large number of villagers had knelt down.

"I called you here today to teach you the extraction method, but... this method won't be taught for free. Families who want to learn this method need to pay 20 coins each!"

Wan Shu exclaimed, "Wow!"

She said that the reason why Li Dagen and Liang Yaozu never mentioned the loss rate and the powder yield was that they wanted to make a fortune by taking this opportunity!
