"You want a lot of salt?"

"Your Highness is wise!"

Guo An quickly replied.

Zhu Di pondered for a moment, gritted his teeth and said, "Don't worry about this, we will ask your father to bring a batch of salt to our Prince Yan Mansion tomorrow!"

"Thank you, Your Highness!"

Guo An bowed his hands and said.

In fact, at this time, there was no shortage of salt in Ming Dynasty.

However, salt is still very expensive for the people to eat, and it is still somewhat scarce. This is because the rulers only want to achieve certain purposes.

It's like pouring out the milk...

This issue is too complicated. Guo An doesn't want to waste his brain cells. He is not qualified to intervene.

Anyway, if Zhu Di wants to get a lot of salt, there will definitely be no problem.

…

After returning to Changshi Division, Guo An sent someone to call on Gong Zhengsuo for Xu Yun!

Probably, in the entire Yan Palace, everyone in the Gongzheng Office loved Guo An, the Right Chief, the most.

Therefore, after receiving the news, Xu Yun immediately put down his affairs and ran over.

"I'm going to see Guo Changshi!"

Xu Yun saluted Guo An with a sincere face.

"Xu Gong is asking for help quickly!" Guo An said with a gentle look on his face.

"Thank you Guo Changshi!"

After Xu Yun got up, he looked at Guo An expectantly.

"I don't know if Guo Changshi came to look for his subordinates, but what orders do you have?"

Guo An said: "We have something to ask Xu Gongzheng!"

"Guo Changshi, please speak!"

"We first need to make a particularly black wooden board, but the black color on the wooden board must not be afraid of washing with water. We have thought about it for several days, but we haven't come up with a solution. I wonder if Mr. Xu has any solution?"

Xu Yun blinked his eyes and asked seriously: "Guo Changshi, you just want the board to be black, but also want it to be so black that it will not fall off easily?"

Guo An nodded: "That's right!"

Xu Yun glanced at Guo An strangely, "Guo Changshi, this is very easy!"

"Um?"

Guo An was overjoyed, "Xu Gong is coming soon?"

Xu Yun said: "Guo Changshi, you only need to polish the wooden board smooth and apply a few layers of black paint on it!"

"Black paint?"

Guo An was stunned, "Can black paint be washed without being afraid of water?"

Xu Yun chuckled and said: "Guo Changshi, don't worry, the paint on many furniture in the house was painted by Xiaguan and others, there is absolutely no paint peeling off!"

"Please don't blame me, Mr. Xu. I've been so distracted by my thoughts these past few days that I actually forgot about the paint!"

Guo An apologized and then made another request: "However, the black paint we want is not just black paint. We also need limestone that can leave obvious white marks on it without scratching the black paint. It's okay."

Easily wipe clean with a cloth!"

Xu Yun still looked confident, "Guo Changshi, don't worry, as long as you give Xiaguan two days, he will be able to concoct this kind of black paint."

"Very good!"

Guo An's face lit up.

"After the black paint is prepared, the worker is making another large piece of wood. This is the blueprint of the wood board!"

With that said, Guo An handed the drawing on the side to Xu Yun.

Xu Yun took a look and saw a wooden board lying across a wooden shelf!

"Don't worry, Guo Changshi, I will definitely be able to make this board within two days!"

Guo An nodded slightly, and then ordered: "In addition, we also need Gongzheng Xu to use limestone and plaster to make small white pillars that are a hundred fingers long but half as thin as the fingers!"

"yes!"

Xu Yun nodded again, and then seeing that Guo An stopped giving any instructions, he quickly stepped forward and asked with curiosity on his face: "I dare to ask Guo Changshi, what is the use of this thing? How much can it be sold for?"

"Sell for money?"

Guo An was stunned for a moment and shook it gently.

"Xu Gongzheng is going to be disappointed. We prepared this for the generals in the school, and we didn't intend to use it to make money!"

"I see!"

Xu Yun's face looked slightly disappointed, but then his smile returned to normal.

"Please rest assured, Guo Changshi, I will make these items in two days!"

"Good work!"
