After traveling through time, I married the prince by signing in

Chapter 215: The Wisdom of Our Ancestors

Yuanman talked to the old lady for a while, and waited until she fell asleep before leaving the house and going to the library.

The remaining books in the backpacks were piled in a corner of the library, and the children would sort them out when they had time. Now all the tens of thousands of volumes were taken out.

Then he called out the manager in charge of sign-in rewards in the imperial capital.

Forty-eight people, all of them were tall and strong, and the empty library suddenly became crowded.

It is not easy to come up with names for so many people, so Yuanman came up with a clever idea. He asked them to find books on the bookshelf themselves, and take a character from the title of the book they got as their name.

The leader is Yuan Kong.

Now that she is pregnant, she naturally cannot do the construction of the shelter herself, so she feels more at ease leaving it to them.

So after Yuan Man waited for them to choose their names, he called them over, gave Yuan Kong 500,000 taels of silver, and asked him to arrange for people to set up shelters in various places in the four countries.

He handed over the plan he had previously made with Hui Chengyuan to him: twelve shelters in each country, forty-eight in total, and it would be just right for the first person to manage one.

"Yuan Kong, I'll give you the plan. Please make all the arrangements and then report back to me."

"Oh, by the way, I have manors in various places. When you choose a location to build a shelter, try to choose a place close to the manor. This way, the people in the shelter can go to the manor to help when they have nothing to do and earn money for their own use."

"Yes." Yuan Kong took the thick stack of plans from her hand.

"This place is left for you. I'll ask Yuanyue to arrange a room for you." Yuanman said as he stood up and left the library.

As soon as he left the library, Yuan Yue came towards him and said, "Master, Yang Chu is back. He knows that you are back too, so he wants to see you and tell you something."

Yuan Man nodded and said, "Forty-eight new stewards have arrived. Please make arrangements."

"Yes." Yuan Yue bowed and responded.

Yuan Man arrived at the meeting hall and Yang Chu was already waiting there.

Seeing her coming, Yang Chu immediately stood up and saluted, "Master."

Yuan Man nodded, "What's the matter?"

Yang Chu told the story of several farms, and then asked: "Master, due to the high transportation cost, I think these cooked foods will only be sold to princes and nobles."

As he was talking about the snacks such as spicy rabbit heads and spicy rabbit cubes that he brought back from the farm in Lingchuan City.

He also took out the bacon, sausage, blood balls, etc. that he had brought back from Zengcheng, and said, "Master, these are what I brought back from various farms."

"Ice is very expensive this year, and cooked food cannot be delivered without ice, so when it is sold, it can only be sold to princes and nobles at a high price."

"If we sell at the previous price, we will only lose money during the summer."

Yuanman was not surprised. It was summer now, unlike winter, when food could be kept for several days.

“How are the sales?”

Yang Chu smiled and said, "Not bad."

"Rabbit prepared food products have the best sales, and rabbits grow fast, so they are also the most profitable."

"However, Zengcheng's pork products are also selling well. Because they are durable, I set the price at 500 coins per pound. Now they have begun to be sold to the State of Zhao."

“The duck products near South City are slightly inferior to rabbits, mainly because they can’t be sold at a high level.”

“So, it’s a small profit but quick turnover model, and it can only be sold locally and in neighboring counties.”

"I have brought some back too. Please try them and see if there is anything that needs to be changed."

Yuan Man looked at the food on the table. Seeing that it was still cold, his eyebrows raised. "Ask the kitchen to heat it up. Let's taste it together tonight and let everyone give their opinions."

Yang Chu smiled and nodded, "Yes."

Yuan Man stood up and walked over to take a look. "Are the prepared foods sold to various places all shipped in ice?"

Yang Chu nodded, "Yes."

Yuan Man lowered his head and thought about the ancient methods of preserving food. The cost of buying ice and transporting cooked food was too high.

The reason why she did not consider buying a vacuum packaging machine from the redemption mall was mainly because vacuum packaging is made of plastic, and those plastic bags are too polluting to the environment.

Moreover, they are not comfortable in this environment without technology, and vacuum packaging is definitely not possible here, so we can only draw on the wisdom of our ancestors.

By the way, historical records show that ancient people also used sealed storage methods to preserve food.

They use pottery jars, porcelain jars and other containers, put food in, and then seal the mouth with wax, mud and other materials to prevent air from entering.

This method can isolate oxygen and inhibit the oxidation reaction of food, thereby extending the shelf life.

When Yuan Man thought of this, he immediately told Yang Chu and asked him to give it a try. If it worked, it could greatly reduce transportation costs.

Ice is expensive in the summer.

However, there is another way, which is to find saltpeter and make ice with it yourself. As long as it is not eaten, there will be no problem.

Making ice from saltpeter is very simple.

After hearing what Yuan Man said, Yang Chu's eyes lit up, "I will arrange for someone to find saltpeter right away, so that we can not only cool our own things, but also sell ice."

Yuan Man nodded, "You can ask Yuan Yue to arrange someone to cooperate with you. I will write you the method of making ice with saltpeter later."

"Yes, master." Yang Chu narrowed his eyes and smiled.

Yuan Man added: "There is another way, that is to set up processing points in each prefecture and arrange for trustworthy people to make it."

"In this way, we only need to transport the chickens, ducks, rabbits, etc. from the farm."

Yang Chu nodded, "Indeed, this is a good idea. Except for the higher cost of enclosing land, everything else is the same."

"You can handle these on your own, whether it's making ice or building a processing point." Yuan Man said as he walked out.

"Oh, remember, the formula must not be leaked."

"Yes." Yang Chu sat there and began to imagine.

Ice making cannot be left behind. Even if you don’t use it yourself, you can sell it to others.

A processing point also needs to be built, and it only needs to be built in the provincial capital.

By the way, the master has an inn in every city. We can just find a place to build it next to the inn and ask the innkeeper to help supervise it.

The more Yang Chu thought about it, the more feasible it seemed, so he began to write a plan.

Yuan Man did not stay on Qinhe Mountain to eat, but took some cooked food back to the villa.

Hui Chengyuan was drawing a map in the yard at this time and had already finished half of it. When he saw her coming back with something, he immediately put down his brush and walked over to her and took the thing from her hand.

"It's so heavy, why don't you let them carry it?"

Yuan Man glanced at the cooked food and said, "I can still lift such a small amount."

"These are sent from farms all over the place. Try them."

"Where's Yuanbao?"

Hui Chengyuan put the things on the table and put away the map. "He and Yuan Rui went to buy things for his younger brother and sister."

"By the way, my father sent me a letter saying that he wanted me to go back and discuss something. I think it's probably about the Yun Kingdom."
