It used to belong to Xindu, and officials all attached great importance to land taxes. The more land, the more taxes to pay. County Magistrate Xu has not developed and utilized it for so many years. This large piece of land must be infertile and not suitable for farming.

Now it has been allocated to Changfeng, but the problem has also been passed to the county magistrate.

Changfeng Town was separated from Tong'an by Fule Village, and the prefecture-general immediately incorporated this village into Changfeng Town, which then became the largest town in Tong'an.

So now Tong'an and Changfeng are adjacent to each other. Isn't this a modern undeveloped town close to the city center?

Gazing at the empty space, Yingying asked, "Do we have much silver in Tong'an?"

The county magistrate was stunned. "A lot! Tongan is the richest among the counties in Yizhou."

"That's good. Isn't it easy to make money from money?"

"What?" the county magistrate asked.

"It's nothing. Here is a blueprint of the building. You can ask a craftsman to see if it can be done." Yingying took out a few blueprints from her sleeve and handed them to the county magistrate.

The county magistrate was not at all surprised by this prophetic event.

He took it with both hands, looked at the blueprint in his hand that looked like a restaurant and a house, frowned and said, "What is this?"

"A department store. It's a multi-story shop that sells everything. It offers a one-stop service for eating, drinking, and having fun."

After a pause, she continued, "Also, after this department store is built, workers will be hired first among those affected by the disaster. With the income, people's lives will get better and better, and Tongan will become more and more prosperous."

As she spoke, Yingying took out a cement recipe from her sleeve.

"It's impossible to build a multi-story building using only adobe walls. Here's the cement formula. Take it and see if you have any of these ingredients."

The magistrate took it with both hands again and looked at it. The limestone and clay were not difficult to find, but the iron ore powder was something he had never heard of. "What is this iron ore powder?"

How to explain it? Could it be ore?

"It's the stone used to smelt iron." Yingying explained vividly.

Master Xu stood aside and watched as Yingying took out things one by one. When he saw that there was finally something he knew about, he quickly interrupted and said, "Sir, isn't it the black stone?"

Yingying frowned: "Black Stone?"

Master Xu said, "Black stone is used in iron smelting."

"Is it a lot?" If it is a lot, then cement may have great uses in the future.

The county magistrate hurriedly said, "The places where black stone is produced are controlled by the government. If you want to use it, you need to apply for it. There is a black stone cave in Yizhou."

"Then this matter can be solved. Now all that is left is to find a craftsman."

The county magistrate did not ask any more questions and went back to his desk to write the application for the black stone.

Mr. Xu stood aside, his eyes drifting towards Yingying from time to time. He still didn't know why the adults listened to the words of a servant, and why she appeared here.

This is something I can only ask privately.

He reported, "Sir, let me take care of the building blueprints."

The county magistrate nodded without even looking up, "Go quickly."

Although he didn't know what the fairy was going to do, since it was something she asked him to do, he didn't have any doubts in his heart.

After finishing the application, the county magistrate sent someone to Yizhou. Then he turned to Yingying and said, "Fairy, I'm going to Qingshi Town to resolve the rice field issue tomorrow. Would you like to come with me?"

The arrival of Yingying on her birthday made the county magistrate very happy, but he was afraid that he would neglect the fairy. For example, he was afraid that the fairy would be damaged by the sun if she went out in the wind and sun.

Yingying's face tightened. "Don't call me fairy from now on. Just call me Madam. Also, from now on, I'll follow you wherever you go. You don't have to discuss it with me anymore."

"Yes, yes, yes." The county magistrate bowed unconsciously and shouted, "Prepare the carriages and horses to Qingshi Town."
