In the South and the Yangtze River Delta, sweet potatoes are usually ripe at the end of August and early September and can be harvested.

However, Changsheng island is located in the north and is isolated from the sea. In addition, due to the influence of the climate of the small glacier, the sweet potatoes of Changsheng island will not be fully mature and harvested until the end of September and the beginning of October.

At this time, it was only early September, and there was still a month to go before sweet potato harvest.

After Li Yuanqing's detailed explanation, Mao Wenlong also understood what sweet potato is.

In particular, Li Yuanqing emphasized that it was a sweet, delicious and pleasant crop with high yield.

Of course, Mao Wenlong would not refuse. He immediately agreed with Li Yuanqing that he would visit Changsheng island in person to watch and taste the sweet potato harvest at the end of September and early October.

It has been nearly a month since I came to the capital. There are still a lot of things about PiDao. I have to wait for Mao Wenlong to go back and deal with it.

Even if Mao Wenlong wants to participate in today's banquet with Yang Guozhu in Xuanfu Town, including other town officers, he really has no time to go back to the inn to pack up his things, and he will rush back to PiDao overnight.

Chen Jisheng, who had been promoted to an official post and made a fortune, still wanted to miss the beautiful gentle town in the capital. But Mao Wenlong wanted to leave, how dare he stay?

He had to follow Mao Wenlong to the Inn and return to PiDao overnight.

Chen Zhong doesn't care here. He can stay if he wants to, and he can go if he wants to.

After Mao Wenlong returned to the inn, Li Yuanqing said with a smile: "elder brother, the southern part of Liaoning Province is stable for the time being. You don't have to rush for this moment. Tonight, finish the banquet. Tomorrow morning, it's not too late to go back. "

Of course, Chen Zhong understood Li Yuanqing's meaning. It was no harm to communicate with his brothers and generals of other armies. He immediately agreed with a smile.

Although it's a day of reward, I've been drinking till midnight last night. I've been tossing about so early this morning. Everyone is tired.

Chen Zhongxian returned to the inn to have a rest. Li Yuanqing left a few soldiers outside the palace gate to inform Yang Guozhu that they had agreed on a good place. He himself returned to the fog rain pavilion to rest.

In the carriage, very comfortable.

It's too early today, and it's a big Dynasty. Xiaolian doesn't come to serve. But the bedding in the carriage is made of fine woolen carpet, with light incense from the Arabian Sea. It's easy to calm down.

Although the appearance of the carriage is inconspicuous and looks a little shabby, the interior of the carriage is not inferior to any of the big men around.

This is also a point that Li Yuanqing has always stressed to Yang jiaoniang.

Especially in places like the capital, "hiding clumsy" is even more important.

The carriage was running smoothly. To be selected as a coachman by Yang jiaoniang, she had to go through at least dozens of times of strict screening, and even the eighteenth generation of his ancestors had to be identified.

Of course, once elected, its treatment is quite generous.

It is not inconceivable that tens or even hundreds of taels of silver a year.

Smelling the fragrance, Li Yuanqing did not feel sleepy, but his brain was very active.

As the saying goes, "food is the most important thing for the people."!

In this era of being shrouded by small ice, food is particularly important.

Therefore, for the growth of sweet potato on the island, it is just like the lifeblood of Li Yuanqing.

From later generations, Li Yuanqing has made it very clear that some problems can be solved by buying grain and grass from places where the climate has been affected a little, or buying the blood and sweat grain and grass of the common people through unscrupulous merchants through trade.

However, if he wants to be prosperous and stable, he must adapt measures to local conditions and at least meet the basic needs of the island.

Even Li Yuanqing once wanted to promote "greenhouses" on the island.

Unfortunately, in this era, without plastic film, other, it is difficult to find this kind of transparent, and enough heat preservation substitute.

Otherwise, as long as the greenhouses can be implemented, not to mention 100000. Even if there are hundreds of thousands of people, or even millions of people, Li Yuanqing is completely sure to take a bite.

Li Yuanqing did not know much about chemistry.

However, he knew that the production of plastic film should not be too complicated, just find the right raw material, dissolve it at high temperature, and press it out with a mold.

However, Li Yuanqing has already returned the specific materials to his junior high school teacher. After returning to the island, he can only rely on his meager memory to explore again.

Thinking of sweet potato, Li Yuanqing can't help but think of Mao Wenlong.

PiDao, including the whole Dongjiang group, has the biggest root. In fact, it is one word, poor!

This is not false poverty, but real poverty.

It is not only poor in materials and money, but also in land and population.

It's mainly about the location of PiDao. It's too limited.

From a strategic point of view, PiDao is indeed the best fulcrum to threaten Zhenjiang, especially Kuandian and Laozhai. However, from an economic point of view, PiDao is small and barren, and the bad thing to say is that weeds will not grow well when they arrive at PiDao.It's better to have the imperial court at the back and Li Yuanqing at the side. But in case, after governor yuan came to power, he blocked PiDao as if in history

Li Yuanqing could not help but spit out a long breath of turbid gas.

As for food, no matter it is sweet potato or greenhouse, he can't afford to slack off.

If it comes to that day, PiDao is short of materials, and the brothers and children can't even eat grass roots. Li Yuanqing, on his side, must stand firm.

……

Back in the fog and rain Pavilion, Yang jiaoniang rushed to meet her. She took Li Yuanqing's arm and said, "Yuanqing, there is good news. Do you want to hear it?"

Looking at Yang jiaoniang who was as excited as a girl, Li Yuanqing couldn't help but smile. His big hand grasped her plump buttocks: "what's the good news? Tell me. "

Yang jiaoniang giggled: "Yuanqing, do you still remember that the vaccinia you asked several doctors to make before was the kind of thing to prevent smallpox?"

"Well?"

Li Yuanqing was stunned, and the spirit of the head was also a burst of, "how? It's got a look? "

Yang jiaoniang nodded, "not bad. With the help of several doctors in Nanjing, Yuan Qing, Mr. Hu and their fathers have successfully experimented with this thing. They have been through dozens of experiments, more than 90% of children infected with smallpox, after vaccination, have been improved. Eight Chengdu was easily cured. The rest, even if there is a small residue, but at most it is only a little scar, and it will not be fatal again

"Really? That's wonderful

Li Yuanqing is not happy.

If the cowpox came out at this time, it would be a great blessing for mankind!

Especially for the Chinese nation.

Of course, for the future slave chieftain Kang Xiaoma, this can only be forgiven Li Yuanqing's incompetence.

"Jiaoniang, where are they now? Call them in now

Yang jiaoniang couldn't help smiling, but she gave Li Yuanqing a look: "what's your hurry! They are still in Nanjing now! This is the news from Kuai ma. I haven't received it for a quarter of an hour! "

"Eh?"

Li Yuanqing just reacted to this, but he couldn't help laughing, but he forced a kiss on Yang jiaoniang's red lips, "jiaoniang, how do you plan to deal with this matter?"

Yang jiaoniang laughed: "Yuanqing, don't you think this is a good opportunity for us to make a fortune! As long as you have these treasures in hand, it's all white money

Li Yuanqing was stunned, but he shook his head and laughed.

In this era, conquering smallpox is undoubtedly equivalent to conquering cancer in later generations.

If according to the future generations of those hospitals, Li Yuanqing even if every day with his butt to people, afraid also can count money to count hand cramps ah!

But!

It's hard for Li Yuancai to cure smallpox!

"Jiaoniang, is it reliable in Nanjing?"

Yang jiaoniang smiles: "Yuanqing, don't worry. Everything is in the fog and rain Pavilion in Nanjing, with my best friend to guard. Unless they don't want to live, they don't dare to move. I've already given them an order. They will come to the capital in ten days! "

Li Yuanqing nodded slowly, for Yang jiaoniang's means, he was very relieved.

To put it bluntly, those who have suffered will never be the same as the flowers growing up in the greenhouse.

Not to mention, it's a secret matter.

"Yes, Yuanqing. How are you going to promote these babies? " Yang jiaoniang suddenly remembered the subject.

Li Yuanqing pondered for a moment and paced back and forth: "promotion? It's too early. The main thing is that I haven't seen the effect of these vaccinia with my own eyes. At this stage, we should focus on training. As it happens, I have trained a group of female guards on the island. After they come back, let them go directly to the island. The training began with the island's female guards and doctors. It's important to let this technology be digested firmly. "

Yang jiaoniang also understood what Li Yuanqing meant.

If you want to use cowpox to make money, it is obviously not enough to rely on a few old doctors.

After all, they are human beings, not immortals. Even if they can receive 100 patients a day, how many can they save? How much money can you earn?

However, Li Yuanqing's training method can cultivate a large number of talents who are proficient in vaccinia in a very short time. Just like a spark, it will soon start a prairie fire.

"Yuanqing, if this thing is done, compared with the fog rain Pavilion, it can only be regarded as a nightpot!" Yang jiaoniang looks at Li Yuanqing's eyes.

Although she has already been as flesh and blood with Li Yuanqing, she can no longer be separated. But even at this time, Yang jiaoniang also has to admire Li Yuanqing's mind. How did he think of him?

Li Yuanqing laughs: "night pot? Not necessarily. You don't know. Do I like this place very much? "How can Yang jiaoniang not understand Li Yuanqing's deep meaning? But Li Yuanqing looked blankly at him and said with a smile, "Yuanqing, as you said, first focus on training. Then, when the training on the island is completed, let's consider the commercial operation. By the way, are you exhausted today? How about the reward granted by the imperial court

Li Yuanqing was lying on the soft couch beside him with a smile: "it's OK. Your brother and I are the right governor of the first grade of Daming. "

"Virtue."

Yang jiaoniang could not help smiling: "Yuanqing, then, do you want to reward you today?"

Li Yuanqing a smile: "how a reward method?"

Yang jiaoniang giggled and fell directly on Li Yuanqing's body and whispered a few words.

Li Yuanqing's pupil enlarged slowly, and said with a smile, "jiaoniang, this is not good?"

Yang jiaoniang gently followed Li Yuanqing's key points and said, "what's wrong with this? Fertilizer and water do not flow into the field. Anyway, they are what I prepared for you. However, Yuanqing, you have to leave the seeds to me... "
