"I haven't told him yet." Su Jinse said with a smile.

Hearing this, Ye Xiange's eyes deepened, and a smile swelled in his eyes, it seemed that Ah Jin was still thinking about him, and he didn't hurt her in vain.

"Uncle Zhu, I want all these potato flour," Ye Xiange's handsome and fair face showed a serious and firm expression, "In terms of price, you can rest assured, it is absolutely fair, and I will give you thirty wen a catty." What do you think? ”

"No problem." Zhang Tiezhu nodded without thinking, even if Ye Gongzi gave him ten cents a catty, he would sell it.

Ye Gongzi has a great kindness to his family!

Ye Xiange paid fifteen taels of silver on the spot, and Zhang Tiezhu packaged all the potato flour.

Ye Xiange said: "Uncle Zhu, in the future, I will want as much potato flour as you want." ”

Zhang Tiezhu frowned in embarrassment, "Ye Gongzi, I don't have potatoes at home, I'm afraid I can't do it." ”

Hearing this, Ye Xiange was very sorry for this.

Su Jinse said with a smile: "Dad, many families in the village and even Zhongyun County have planted potatoes, we can buy them!" ”

Zhang Tiezhu's eyes lit up: "This method is good!" Let's find someone to buy it! ”

Early the next morning, Zhang Tiezhu and Li Hongxiang went around buying potatoes, and everyone knew that this Zhang Tiezhu's family was buying potatoes to make potato flour, so they sold them all.

They can't make this potato flour, so it is better to sell it for money, and then they can buy some grain, oil and salt.

However, everyone did not sell them all, but left some potatoes at home to prepare for the spring to raise seedlings.

After buying potatoes in the village, Zhang Tiezhu and Li Hongxiang drove ox carts to other villages to buy potatoes.

During this time, Ye Xiange stayed in Shangzhuang Village again, it is early winter, the weather is cold, there is no work to do, and there is no need to build a water dam or anything, so it is very idle.

Ye Xiange was idle, so he accompanied Su Jinse up the mountain every day to play, or pick wild seeds to eat.

Half a month later, the purchased potatoes were finally made into potato flour, this time there were more purchases, all of them went to ten miles and eight townships, and almost the entire Zhongyun County ran all over, and a total of 700 catties of potato flour were made.

So Ye Xiange and Tang Yan left again, saying that they would let people bring silver to collect potato flour in half a month.

What did Ye Xiange want to buy these potato flour for, Zhang Tiezhu didn't ask in detail, and thought that Ye Xiange was going to sell it.

In the winter of this year, there was a war between the frontier of Dongyu and the Beizhen country of Linguo.

The soldiers of the Northern True Kingdom are strong, brave and good at fighting, good at riding and shooting, and have been living a nomadic life in the grassland.

This time they violated the frontier of the Dongyu Kingdom and fought a stalemate.

However, winter is coming, the sky is covered with goose feathers and heavy snow, the soldiers of Dongyu Kingdom are gnawing dry food, lack of strength, and the soldiers of Beizhen Kingdom come to sneak attack from time to time, making them miserable, they are not the opponents of Beizhen Country at all, and they are defeated and retreated.

Beizhenguo is used to the cold, he wears wool and cowhide velvet, and he gnaws beef, and he is tall and big, so Dongyu is very disadvantaged in this regard.

Just when they thought that Dongyu Kingdom would not be able to support it, it turned out that there was a thing called potato flour in the military camp of Dongyu Kingdom, which was easy to cook, just add water and some seasonings, and eat warmly, finally don't have to worry about the Beizhen Kingdom coming to attack at any time, they will not have time to prepare.

In the last battle, Dongyu Kingdom won.

His Majesty Dongyu Longyan Dayue asked General Su where the potato flour came from, and General Su said that it was brought by Ye Xiange, so His Majesty went to send someone to announce Ye Xiange's entry into the palace.

In the end, I learned that this potato flour was actually researched by Zhang Tiezhu!
