I am the empress, you still tell me to run away?

Lin Xuan returned the salute to the two of them.

Well, it seems that I can't just eat fish for lunch, I need to prepare more.

Because when he got closer, Lin Xuan could clearly hear Dr. Nong Li Zhongnong's stomach growling.

According to the original living habits, Lin Xuan would ask Xiao Luoli to cook the corn so that he could have lunch when he came back.

It's just that last time the corn was eaten by Zhao Yuehan and the old servant Li Mu, and finally had to make a new lunch.

Therefore, Lin Xuan simply arranged to eat corn for dinner, and he could go to bed after eating the corn. As for if a guest came at noon, it would be too rude to just let him eat the corn.

"The two of you are taking a break here, and I'll go prepare lunch first!"

Without waiting for the two to agree, Lin Xuan walked to the pond, fished out a big fish from the fishing net and went to the back kitchen. By the way, he arranged for Xiao Luoli to wash two sweet potatoes and bring them over.

After a while, cooking smoke rose from the chimney, sweet potato and white rice porridge was cooked in the big pot, and braised fish in braised sauce was cooked in the small pot.

On the same table, Uncle Fu and Li Zhongnong ate with smiles on their faces and feasted on their mouths.

【No wonder His Majesty likes coming here so much. 】

However, they quickly shook their heads again. His Majesty probably didn't come here just for a bite to eat, but probably because of Lin Xuan's talents.

After eating and drinking enough, the bowls and chopsticks were taken away by Xiao Luoli.

Under the grape trellis, Lin Xuan cut a bunch of grapes with his sword and put them on the table.

Li Zhongnong humbly let the elders ask Uncle Fu to ask Lin Xuan some medical doubts.

At the same time, Li Zhongnong was more and more shocked by Lin Xuan's talents.

You know, after going to court, he rushed over to Lin Xuan's small courtyard immediately, wanting to ask some questions about the cultivation and production of immortal food. Arrived at the old doctor under the grape arbor.

The old medical sage immediately stood up and saluted, and introduced himself: "Uncle Fu, I am a doctor who lives in Zhao's Mansion in Yongle Lane. I came here to ask Uncle Le Xian some medical skills."

Li Zhongnong was numb at that time!

The old medical saint, others don't know him, but he does.

The old lady in the family had a special diagnosis and treatment by the old doctor, prescribed a few medicines, and now her health is much better, a real old fairy!

Who would have thought that the old medical sage would come here, especially to ask Lin Xuan for advice on medical issues.

Papermaking, medicine, agriculture...

Just these three kinds have already broken through Li Zhongnong's cognition.

I really don't know how much talent and learning this Lexian Bo Honglu Temple Chancellor Lin Xuan still has that has not been revealed.

His Majesty treated Lin Xuan kindly and respected the corporals, what he did was really right.

Just one item of immortal food can benefit tens of millions of people.

In addition, the old doctor's self-introduction made Li Zhongnong understand something.

He hurriedly replied: "Li Zhongnong, a doctor of agriculture in Xiataifu Temple, came here to ask Mr. Le Xianbo about agriculture."

This time it was the old doctor's turn to be a little startled, and he was more and more impressed by Lin Xuan's talents.

The two exchanged briefly for a while, tacitly understanding each other.

Thus, there was the scene of "respecting each other as guests" that Lin Xuan saw when he returned home.

The breeze is gentle, the willows are Yiyi, I know it.

Under the grape trellis, Fu Bo began to ask questions related to "Medical Strategy", and Lin Xuan answered them one by one.

To be honest, Lin Xuan really admired Fu Bo's medical attainments. Basically, if he answered one point, Fu Bo could generate countless points.

Fortunately, "Medical Strategy" is almost equivalent to extremely basic medical common sense for modern people, otherwise Lin Xuan would not be able to answer it.

Here, Lin Xuan mainly introduced medical microscopic knowledge points to Fu Bo.

For example, the tissues of the human body are made up of cells.

Bacteria, viruses, and microorganisms exist in the world invisible to the naked eye, and Mohists took out a wooden stick, which can be cut off indefinitely, until it is invisible to humans, as an analogy.

Taking this opportunity, Lin Xuan reluctantly explained the pathology of wound infection, human illness, etc.

There are also instructions for vaccinating against smallpox.

When mentioning this matter, Uncle Fu didn't know what sad things came to his mind: "Uncle Le, if this method of vaccinating smallpox to prevent smallpox is really effective and popularized, there will be countless children who can grow up safely. It really benefits the common people of the Li people!"

Lin Xuan waved his hand and said with a smile: "Hey, it's not my credit, it's all discovered by the former sages, and the credit belongs to them."

Uncle Fu shook his head: "No, Uncle Le Xian is being modest. What you have done is like stealing the Heavenly Book from the Emperor of Heaven and saving the common people below. Your contribution is no less than that of the previous sages who created this method!"

Dr. Nong Li Zhongnong said at the side: "That's right, Le Xianbo, don't be humble."

Soon, he remembered that his youngest daughter was about eight years old and was about to develop smallpox, so he quickly asked if she could be vaccinated.

Lin Xuan nodded: "Well, according to the method in the medical strategy, you can be vaccinated. After the inoculation, the body will have antibody factors to defend against smallpox virus, and basically will not get smallpox."

"However, I don't have any cattle here, you can let Uncle Fu try it."

"In addition, Forber can also pass on this method to other doctors and let them promote it."

Forbe wanted to ask again if he could pass it on to others.

Although I asked about it last time, this "Medical Strategy" was produced by Lin Xuan after all. You must know that many aristocratic families have some prescriptions, and they don't have a lot of money, so they won't pass it on privately, let alone show it to others.

However, Lin Xuan said without hesitation that he could spread the word.

This is the great mercy of the doctor!

Uncle Fu admired Lin Xuan more and more in his heart.

At the same time, Uncle Fu felt a little regretful. It would be great if he could live another hundred years and learn more medical knowledge from Lin Xuan!

"I'm going to trouble Uncle Fu about the little girl getting vaccinated!"

Li Zhongnong bowed his hands to Uncle Fu.

To tell the truth, Li Zhongnong would be a little more skeptical if other doctors said that vaccination with vaccinia could prevent smallpox.

However, it came from the mouth of the old medical sage with wonderful hands and rejuvenation, so he was [-]% convinced, not to mention Lin Xuan who took out the fairy food as a guarantee.

Little Luoli sat on the side, watching the adults talking with a puzzled face, as if thinking, as if realizing something, but she didn't understand why.

It can be seen that Uncle Fu and Li Zhongnong admire the master very much.

I feel that the master is really amazing!

"Oh, Luo Li can also be vaccinated with cowpox at that time."

Lin Xuan saw the cute little Luo Li beside him, and said with a smile.

Little Luoli trembled, feeling a little frightened for no reason.

……

After Fu Bo asked questions, they ate some grapes, drank some tea, and took a short rest.

Li Zhongnong, a doctor of agriculture, began to ask Lin Xuan how to take care of the fairy food, increase the production of fairy food, and whether the roots of sweet potatoes and potatoes can be separated indefinitely, and new land can be cultivated to continue planting.

Regarding Li Zhongnong's question, Lin Xuan felt a little speechless.

If the stems and leaves of potatoes and sweet potatoes can't grow, how can they grow?

However, there is nothing better than walking around the land, demonstrating and explaining this kind of thing.

"Dr. Li, please follow me."

Lin Xuan brought Dr. Li Zhongnong to the backyard.

Although most of the potatoes and sweet potatoes were taken away, and a lot of corn was taken away, there were still a lot left, enough for Lin Xuan to eat.

Uncle Fu picked up his crutches with a smile, and followed him in.

Little Luoli followed, supporting Uncle Fu to prevent Uncle from falling.

"Forbe, the weather is hot, you can sit under the small pavilion in the backyard to rest, so that you can still hear us talking."

Entering the backyard, Lin Xuan pointed to a small pavilion in the middle of the field for temporary rest.

Originally, there should be rockeries all around, but the big ones were pawned off by the elders of the family.

The remaining small stones were cleared aside by Lin Xuan, either paved as a road, or piled up on the side, which barely had some ornamental value.

There is a ditch in the backyard, and the ditch is connected to the pond in the front yard. This can roughly ensure that the water in the entire mansion is active and will not become stagnant water, and it is also convenient for irrigating the miscellaneous crops in the backyard.

If it is necessary to draw water from the front yard every day in order to water a little, when it comes to the back yard, Lin Xuan alone must die.

Uncle Fu held his hand, and Luo Li led him to the small pavilion. Looking at the crops all over the yard, the frown on his face relaxed.

"First, let's say this corn."

Lin Xuan pointed to some newly planted corn seedlings in the open space.

Because most of them were poached by Taifu Temple except for the leftover food, he had to plant some more.

"Corns drink water. If you want corns to grow bigger, you need to water more. If you have enough water, you can grow fast."

"In addition, when the corn seedlings are a little bigger, you can sprinkle some farmyard manure around the seedlings to speed up the growth of the corn seedlings."

Lin Xuan picked up the hoe and removed the weeds on the side.

"These weeds should also be removed as much as possible, so that the corn seedlings can maximize the absorption of nutrients from the surrounding land."

"Uh-huh."

Dr. Nong Li Zhongnong stood beside Lin Xuan, nodding repeatedly.

Although this part is written in the materials provided by Lin Xuan, it is obvious that learning more closely will yield more benefits.

However, Dr. Nong Li Zhongnong's eyes quickly focused on the hoe used by Lin Xuan.

You must know that there are only a few copper tools for their work in the fields.

Most of the tools used are stone tools, bamboo, wooden sticks...

What is Lin Xuan using?

It looks like copper, but it doesn't look like copper.

"These are sweet potatoes. After they grow to a certain extent, some manual sifting can be done to pick out the stems and leaves. They can be used for planting the second round, or they can be used to stir-fry vegetables."

"However, these stems and leaves need to be processed a little before cooking."

Lin Xuan picked some and made a demonstration.

Probably fried sweet potato leaf stalks.

It's just that this dish is a bit oily, and if there is less salt, the taste will be a bit off.

But for the peasants, it should be considered a good dish.

After all, there is grain growing underneath, and the leaf stalks on top can also be cooked and eaten, which is very profitable!

"As for how to eat sweet potatoes, put sweet potatoes in the porridge you drink at noon."

Lin Xuan took the rake on the side and dug out some sweet potatoes from the ground. By the way, he put the sweet potatoes aside to show Li Zhongnong how to pile up the stems.

Simply put, growing sweet potatoes requires loose land and easy digging.

Therefore, it is the best way to dig out the underground soil and pile it into long triangular strips, and plant the seedlings on top.

In this way, after the sweet potatoes grow, they will first occupy the loose soil area piled up.

The method of planing the sweet potatoes just now is to show Li Zhongnong the area where the sweet potatoes grow.

Li Zhongnong has gained a lot, and his expression is excited.

Finally, there are potatoes, and there is nothing to say about potatoes.

It is worth mentioning that potatoes are suitable for planting in colder areas, which can effectively avoid pest damage.

Planting potatoes in relatively warm areas is prone to insect damage, so Li Zhongnong needs to pay attention when planting.

At the same time, it is best to harvest and store potatoes before winter.

Otherwise, it will be frozen in the soil and damaged by the cold winter.

Most importantly, when storing potatoes, always keep an eye out for sprouted potatoes.

These potatoes are poisonous, and people who eat them will be poisoned and even die.

Lin Xuan explained these one by one.
