She married a dying prince and she won three babies.

“What Master Wan said is true.

In this way, I will send someone to cooperate with you in this matter, and the business will be run with my investment, but the profits will be split 20:80 with Fengrong Prefecture.

This princess has the final say over her own fiefdom, and I don’t think the emperor will say much.

Part of the money received by the government must be turned over to the national treasury.

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

Yu Yuanzheng thought of a way.

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

But she will not take the main role, the government will have to take the majority.

She sent someone here just to supervise.

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

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

If the fruits do not ripen at the same time, you can dry the dates and store them, then steam them when needed.

Brewing these two fruits together might produce unexpected results, so you can try it more often."

Yu Yuanzheng suddenly thought of another approach.

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

Of course, she also told Mr. Wan to do more experiments during the process and not to do it exactly as she wrote.

People's brains are flexible and can innovate through experimentation.

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

When the adults were talking about serious matters, Yu Yuanzheng did not let the three children leave.

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

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

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

Although children don’t understand what adults are saying, they are the most sensitive.

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

Yu Yuanzheng and his wife were stunned when they heard their child's question.

How to answer this?

"My dears, when you grow up a little bit, Mommy will tell you, okay?

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

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

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

"Look, your father is a skilled warrior who can defeat the enemy, but 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 Yuanzheng praised Shangguan Ziqi so much that the children nodded in approval.

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

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

The couple taught their children in tacit understanding.

The three children approved very much.

The family of five is very warm.

Just then, Lian Qiao came in.

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

"Bring it all here, we'll eat together," the prince ordered.

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

Three kids can add a lot of laughs.

"Yes, Your Highness the Crown Prince."

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 with 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 missed his two children, the younger one was only a few months old.

Then he also picked up the chopsticks to help the three children pick up some food.

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

This is what Yu Yuanzheng requested.

Enhance the relationship between parents and children.

The affection between parents and their children arises naturally from the day of conception.

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 Yuanzheng naturally knows something about psychology.

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

That makes 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.

Had a night's rest.

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

He also asked Lord Wan to move the Fengrong Mansion's official records 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 Mansion.

But it's not 100% certain.

Let’s read the provincial annals together.

Yu Yuanzheng also took a copy to read.

They all record the major events that 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 reading the local gazetteer but found nothing useful.

I guess there wouldn't have been any clues left about the treasure back then.

If anyone were to discover it, it would surely attract covetousness from all sides. The previous emperor would have to 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.

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

I can't tell anything from the picture.

February 28th.

Shangguan Ziqi selected fifty people and left them in the inn to protect Yu Yuanzheng and her three children.

Yu Yuanzheng 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 all three countries have 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 five doctors from each county and ten doctors from the provincial capital.

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

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

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

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

Spring plowing is about to begin, which is the critical time to use cattle. Moreover, cattle are the lifeblood of farmers, and they are reluctant to sacrifice them.

How to solve this problem?

Yu Yuanzheng was also in trouble.

She couldn't delay the farmers' spring plowing.

A year's plan starts in spring, and no time can be wasted.

There was no other way, so the matter had to be put on hold for the time being. However, Yu Yuanzheng bought the few cows that had been found and used them to vaccinate a small number of people and also for teaching.

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

Every doctor studies it seriously, and it’s actually not difficult.

You will get it after reading it once.

But it is not easy to find cows infected with cowpox.

Yu Yuanzheng started the publicity work before the spring plowing began.

Many people do not know the benefits of vaccination.

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

Some people living in the mountains rarely go out a few times a year, so they don’t even know about it.

So this promotion takes a lot of time.

Yu Yuanzheng wrote a propaganda notice that the people could understand immediately, and asked Mr. Wan to distribute it to all counties, and then from the counties to all towns and villages, making sure that the village heads and neighborhood heads at the lowest level convey the content to every citizen, no matter what method they use.

While Yu Yuanzheng was teaching the doctor, several maids and children watched from the side.

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

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

The location of the imperial tomb of the previous dynasty is very special, it is actually 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, he changed the name of the mountain to 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 and flow into a river called Jiuhui River. Of course, its source is not here, but goes all the way to the northwest for an unknown distance.

Moreover, the river is surging and extremely turbulent 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 tombs are covered with trees and weeds due to their age.

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.
