"Master Wan said yes.

In this way, the head of the family would send someone to cooperate in this matter, and the head of the family would invest in the business, but the income would be shared with the government office at eight points.

This lord has his own fiefdom and I can make the decision on my own. I guess the emperor won't say much.

The government had to pay part of the money it received into the national treasury.

If the government has more money, wouldn't the amount of money handed in be more? The emperor will be more satisfied. "

Yu Zheng thought of a solution.

This way, it wouldn't be difficult for Lord Wan. It was like she and the government office were doing this together.

But she will not play a major role, the government will have to take the majority.

She sent someone just to supervise.

"That's really great." Lord Wan smiled happily.

"Also, dates have the highest sugar content. You can encourage people to plant more date trees, or add some dates to other foods.

If the dates are not ripe at the same time, you can dry them and store them, and then steam them when needed.

Brewing these two kinds of wine together may have unexpected effects. You can try it more often."

Yu Yuzheng suddenly thought of another approach.

Without further ado, Yu Zheng wrote down everything she had just said on the spot, and then added some of her own thoughts.

At that time, she also told Mr. Wan to do more experiments during the process and not to do it completely according to what she wrote.

People have flexible brains and can innovate through experimentation.

Just like the prince making bombs, their power becomes stronger and stronger as they are continuously developed based on the previous ones.

When the adults were talking about serious matters, Yu Zheng did not ask the three children to leave.

The three children did not interrupt the adults' conversation and listened attentively.

After Lord Wan left, the three treasures turned to Yu Zheng.

"Mother, why do you know so many things, while father and the prince don't?" Dabao asked first.

Although they don't understand what adults say, children are the most sensitive.

He could clearly feel that his mother was smarter than his father.

When Yu Zheng and his wife heard about the problem with their child, they were stunned.

How to answer this?

"My dears, when you grow up a little bit, I will tell you, right?

Your father and the prince are not stupid, but they have not learned what mother has learned, so they don't know.

If they learn the same things as mother, they will be smarter than mother."

Yu Yuzheng did not speak ill of their father in front of the children, but wanted to establish an all-round father for them.

"Look, your father is a skilled warrior who can defeat the enemy, but your mother is afraid of even a dog.

Your father can lead thousands of troops to fight, but mother can’t. She can only bandage the wounds of the injured soldiers.”

Yu Yuzheng praised Shangguan Ziqi so much that the children nodded in approval.

"Daddy is the best." Bao hugged Shangguan Ziqi's legs.

"Daddy and your mother each have their own abilities, do you understand?" Shangguan Ziqi followed Yu Yuzheng's words.

The couple taught their children in tacit understanding.

The three children approved very much.

The family is very warm.

Just then, Lian Qiao came in.

"Prince, Princess, the meal is ready. Should we bring it here or next door?"

"Bring them all here so we can eat together," the prince ordered.

The prince found it more fun to have dinner with Shangguan Ziqi's family.

Three kids add a lot of laughs.

"Yes, Your Highness."

After a while, two maids brought in the food.

The three children will be four years old in two months.

They can eat by themselves using a spoon, but they need adults to pick up food for them.

The prince was very happy to see Shangguan Ziqi and his wife busy.

He also misses his two children, the younger one is only a few months old.

Later he also picked up the chopsticks to help the three children pick up some dishes.

Whenever the couple is with their children, they try to take care of them themselves.

This is Yu Zheng’s request.

Enhance the relationship between parents and children.

The affection that parents have for their children develops naturally from the day they are conceived.

But a child's affection for his parents is developed through day-to-day nurturing and teaching.

That’s why there is a saying that the grace of raising a child is greater than the grace of giving birth to a child.

As a doctor, Yu Yuzheng naturally knows something about psychology.

When she told Shangguan Ziqi this idea, he thought about it for a while before nodding.

That makes a lot of sense.

From that day on, Shangguan Ziqi would take his three children out to play whenever he had the chance.

Taking care of children has never been a problem.

Rested for a night.

The next day, the prince and Shangguan Ziqi continued to study the map.

He also asked Lord Wan to move the official records of Fengrong Mansion to the inn. The earlier the better.

They wanted to look for any relevant records in the local annals, to see if there would be any clues or hints.

Based on their analysis of the map and the treasure map, they concluded that the treasure was most likely in Fengrong Prefecture.

But it's not 100% certain.

Let’s read the provincial annals together.

Yu Zheng also took one to read.

They all record what major events happened in Fengrongfu in which year and month, as well as some culture, customs, products, etc.

There are no useful clues at all.

I spent three days looking through the local gazetteers but found nothing useful.

It is estimated that when the treasure was hidden, no clues were left at all.

If people were to notice it, it would surely attract covetousness from all sides. The previous emperor would definitely keep it secret.

However, the location of the imperial tombs of the previous dynasty is recorded.

"Your Highness, let's go to the imperial mausoleum first to take a look. The location marked on the treasure map does look like it's near the imperial mausoleum." Shangguan Ziqi suggested.

"Well, let's go there first and look at the terrain there." The prince agreed.

I can't tell anything from the picture.

The eighteenth of the month.

Shangguan Ziqi selected ten people and left ten people to guard Yu Zheng and her four children in the inn.

Yu Zheng did not ask to go with them.

Let them first familiarize themselves with the terrain, draw it, and then discuss it together.

She planned to take the children to stroll along the streets and experience the local customs and culture.

She also had to arrange for the people to be vaccinated against smallpox.

Now the three countries have all obtained this technology from her, so there is no need to keep it secret.

She went directly to the government office and found Lord Wan.

Please ask him to issue a notice to recruit one doctor from each county and ten doctors from the prefecture.

She wanted to train people on how to vaccinate against cowpox, how to identify cows with cowpox, how to cultivate more cows with cowpox, and how to treat the cows afterwards.

After hearing Yu Yuzheng's plan, Lord Wan was very enthusiastic and sent letters to the county magistrates on the same day.

A few days after the letter was sent, the doctor arrived and several cows infected with cowpox were found.

However, some farmers were unwilling to lend their healthy cows to be infected with cowpox for the purpose of extracting milk.

Spring ploughing is about to begin, which is the critical time to use oxen. Moreover, oxen are the lifeblood of farmers, so they are simply reluctant to sacrifice them.

How to solve this problem?

Yu Zheng was also in trouble.

She couldn't delay the farmers' spring ploughing.

A year's plan starts in spring, so there can be no delay.

There was no other way, the matter had to be put on hold for the time being, but a few cows had been found, and Yu Yuzheng bought them directly. He used these cows to vaccinate a small number of people and also used them for teaching.

Teach people first, and it won’t be too late to proceed after the spring ploughing is over. Anyway, there is no epidemic outbreak now.

Every doctor studies it seriously, and it is actually not difficult.

You will get it after reading it once.

It’s just that this cow with cowpox is not very easy to find.

Yu Yuzheng started the publicity work before the spring ploughing started.

These people don't know where to get the vaccination.

After all, it's impossible for them to be well-informed.

Some people living in the mountains rarely go out of the mountains a few times a year, let alone know what is going on.

So this promotion takes a lot of time.

Yu Yuzheng wrote a propaganda notice that ordinary people could understand immediately and asked Mr. Wan to distribute it to all counties, which would then send it to all towns and villages. He made sure that the village heads and borough heads at the lowest level conveyed the content to every citizen, no matter what method they used.

When Yu Zheng was teaching the doctor, several maids and children watched from the side.

When she was done, she took the children for a stroll on the street.

Besides, the prince and Shangguan Ziqi set out for the location of the imperial tombs of the previous dynasty since that day.

The location of the imperial tombs of the previous dynasty is very special, it is located on a mountain.

And this mountain is called Jiulong Mountain.

This name should not have been used, but since a Feng Shui master discovered that this was the location of the dragon vein, the mountain was renamed Jiulong Mountain.

There are nine peaks on this mountain, and the most amazing thing is that the water from each peak forms nine streams, which then converge into a river called Jiuhui River. However, its source is not here, but flows to the northwest for an unknown distance.

Moreover, the river is surging and extremely fast in some places.

The prince, Shangguan Ziqi and others inspected the imperial mausoleum and its surroundings, and walked around the nine peaks, but they didn't see anything special.

Even the imperial tomb is so old that it is overgrown with trees and weeds.

If it weren't for the remains, it wouldn't be visible at all.

The entrance is nowhere to be found.

However, it was already closed, and there had been two earthquakes in over a hundred years, making it even more difficult to determine its location.

"Your Highness, this is not easy to find." Shangguan Ziqi was a little frustrated.
