Today, Xie's Luoshui traveled overseas for two years and brought back the divine seed. Great achievement! He was conferred the title

of Marquis of Luo County. Cowpox is a mild smallpox

that cows can get. If you want to implement the cowpox method, you have to find a cow with smallpox. Fortunately, it is not difficult to find.

In addition, the old emperor also summoned famous doctors from all over the world to discuss the prevention of smallpox. The power of this matter... How to say it, a doctor is already over 80 years old, and his children are afraid that he will die from the long journey, so they want to report to the government for him. The doctor said that even if he has to be carried, he must be carried to the capital! Doctors

in the world: Get out of here, today is the day to bring honor to our family!

The former Jin princess Mao Jiuzhou also entered the palace and read the ancient book with other doctors to discuss the feasibility of human pox and cowpox.

The final result of the discussion was: "Cowpox is indeed better than human pox, but cowpox cannot be inoculated randomly. The region, climate, time, and even the physical condition of the person who provides the cowpox will affect the efficacy."

They cited the example of the eastern Guangdong region.

Guangdong is low and humid, and many people are suffering from madness. If cowpox is obtained from such people and injected into other people's bodies, it will cause great harm.

In response, Mao Jiuzhou proposed: "Don't rush to vaccinate, this ancient book needs to be improved."

Xu Yanmiao sat next to him and exclaimed throughout the whole process.

[It turns out that it is not just necessary to infect people with the pox plasma from cows and then extract the vaccine! ]

[It turns out that there are so many tricks. Fortunately, I didn't do it myself, otherwise I would have harmed people. ]

[Oh oh! We also have to consider the storage of smallpox vaccine! Fortunately, it's good that professional people are really needed for professional matters! 】

Xu Yanmiao felt much more relieved that this matter could be put on the agenda.

Now in front of him is another matter -

the old emperor summoned all the ministers to see the potatoes, sweet potatoes and corn brought back from America by the long-distance fleet!

Qin Guan glanced at Xie Luoshui: "Are you very nervous?"

Xie Luoshui pursed her lips and nodded.

After all, it was related to whether she could be made a marquis.

Qin Guan decided to say something to divert her attention: "How is Xiaodong's teeth? What did Doctor Mao say?"

Xie Luoshui showed a sad look on her face: "It's rotten and can't be cured."

Two years of drifting on the sea is never an easy thing. People on the ship are more or less sick.

The same is true for Xiaodong mentioned by Qin Guan.

This man can no longer eat food with bones and tendons. He can only eat white rice with vegetables and tofu, and it must be cooked very soft. It is impossible for him to eat big fish and meat.

Even with Xie Luoshui's physique, she had several serious illnesses on the ship, but she recovered quickly.

Qin Guan used his right fist to hit the palm of his left hand and said, "I have been with His Majesty for many years. He has always been clear about rewards and punishments. He will never let us down or let down the brothers on the ship."

Xie Luoshui also believed this.

The two looked up together. His Majesty was opening the box they brought back in front of everyone to display the real objects.

- As for the seeds, of course they were stored separately and could not be taken out and exposed to the outside world at will.

The old emperor's hand, which was so stable when he bent the bow and put the arrow, actually trembled.

The lid was opened, and the cloth was untied layer by layer. He first saw the corn.

It was about as thick as a child's arm, and was wrapped in green skin. The old emperor took it out, peeled off layer after layer of green skin, and revealed the jade grains inside that looked like a beautiful woman smiling with teeth showing, flowing with brilliance.

When it was held in front of everyone, the officials who controlled the country's center were all speechless.

Not only because this thing called corn looked good, but also because Xie Luoshui said: "This thing produces 180 catties per mu!"

- When they arrived in America, it was harvest time soon. It was just convenient for measurement.

And now the average yield of staple food in Daxia is:

112 catties of millet.

112 catties of wheat.

353 catties of rice.

Although rice has a large yield, it is too picky about the soil. According to Xie Luoshui, corn can be grown in the mountains! In other words, it does not require much water and fertile soil!

- Of course, Xu Yanmiao had said this a long time ago, but they had to find a source for this, right? They couldn't pretend to know more about the situation than Xie Luoshui, who had personally gone to America.

The old emperor pushed aside three or five corns and took out potatoes from them. The size of these potatoes was like apples.

Xie Luoshui shouted: "This thing produces 572 kilograms per mu!"

The old emperor took out sweet potatoes.

Xie Luoshui almost pulled his throat hoarse: "This thing, per mu -"

"Thousand kilograms!!!"

Thousand kilograms!

Ten times that of wheat and millet! Three times that of rice!

*

Corn, potatoes, and sweet potatoes were passed around among these officials. They rubbed the dirt off the corn, broke open the leaves, and carefully stroked the corn ridges. They carefully held the potatoes and gently sniffed the familiar smell of digging from the ground. The sweet potatoes had been stored for more than half a year, and had already sprouted and dried up, like an old man's fingers, ugly and dry, but no one rejected them.

They held these things in their hands and couldn't help crying. They

cried for the famine, the disaster years, and all the people who died of hunger in the past.

No more hunger! No more hunger in the future! No one will die of hunger no matter how poor they are!

As they cried, they began to laugh. It was an ugly laugh with tears streaming down their cheeks.

But they wanted to laugh!

The old emperor raised the sweet potato in his hand high and said: "From now on! Natural disasters will no longer bring famine to Daxia!"

You say! How can it not be worth laughing! ! !

That day, cheers, applause, and laughter resounded through the sky.

Only Ilala, a Native American, felt out of place and lonely.

He looked at these Daxia people with some confusion: Why did they suddenly cry and laugh while holding those things dug out of the ground?

Corn is the sun god, and he can understand crying and laughing while holding Him, but why did the other two things cause such a big reaction from them?

＊

Ilala was invited to Daxia because Qin Guan and Xie Luoshui discussed and decided to invite a native to teach them how to grow potatoes, corn, and sweet potatoes.

In addition to planting, there are also how to store and how to select seeds. If they rely on themselves to explore these, it is unknown when they can promote them.

Although they don’t speak the same language, they can learn by doing it one by one!

For example, the Paraguayans have mastered a potato freeze-drying technology: wash the potatoes and then freeze them, squeeze out the water after thawing, and dry them outdoors. In this way, potatoes can be stored for a long time.

- They have used this method for at least two hundred years.

There was also potato disease - they didn't know how to describe it specifically. They only knew that there was a tribe that only planted one kind of potato, and that tribe later starved to death.

There are hundreds of varieties of potatoes in the Americas. Under the enthusiastic guidance of the Paraguayans, Xie Luoshui and others successfully selected more than ten kinds of potatoes and brought them back to China. They were all big.

"Xie Luoshui!" The old emperor held the sweet potato in one hand and beckoned her forward with the other.

Xie Luoshui guessed something, her heart skipped a beat, and she was stunned for more than ten breaths without coming back to her senses.

The old emperor was very patient about this.

He still looked at Xie Luoshui with a smile until Xie Luoshui came back to her senses and trotted to him.

The old emperor joked: "If you were not in front of me, you would have wanted to do a somersault while running, right?"

Xie Luoshui said with a smile: "Your Majesty, Luoshui is indeed very excited."

The old emperor also laughed: "I should be excited."

"I will be rewarded with a title

of nobility. I will not break my promise." Xie Luoshui clasped his fingers tightly in his palms, and his voice was a little hoarse: "Minister, thank you for your kindness, Your Majesty!"

"Hahaha! Don't be in a hurry to thank me, you don't even know what title you should be given!"

Emperor Tiantong laughed loudly. His face suddenly changed: "Xie Luoshui, come forward and listen to the title!"

Xie Luoshui's face suddenly calmed down.

As if he had done it thousands of times, he walked forward steadily and knelt down.

The emperor looked down at her and said, "You will be granted the title of marquis for your merits. Now Xie Luoshui has traveled overseas for two years and has brought back the descendants of the gods. Great merit! You will be granted the title of marquis of Luo County, with a fief of 500 households."

It was as if some sound was hitting her eardrums and heart, and every heartbeat seemed to be about to burst out of her throat.

For a moment, the expression on Xie Luoshui's face and the thoughts in her mind became blank.

She seemed unable to hear any other sounds, and could only grasp the words "marquis of Luo County".

At this moment, she felt like a weed in the wind, floating lightly, swaying, and so unpromising that she seemed to faint at any time.

Luo County was where she had lived since she was a child, and the emperor granted her the title here so that she could return home in glory.

This was not enough.

She heard the voice of His Majesty again.

"A post of Crossing the Sea General is established, with a rank of seventh grade. I will specially confer you the title of Crossing the Sea General."
