This rapeseed system has never said whether it will be in the future, Xu Yunjin has been thinking about getting some vegetable oil, but he didn't expect to meet rapeseed.

"Yes, county lord."

For Xu Yunjin's proposal, the emperor not only allocated funds to the research institute to transfer people, but even prepared a piece of land for the research institute.

Qi Ren gave Xu Yunjin so much trust, Xu Yunjin will do everything to help the research institute, even if there are wild plants she doesn't know, but isn't there still a little one.

Xu Yunjin took a closer look at several other plants, several kinds of wild vegetables can be used, but the taste and appearance are strange, and the people are afraid to eat them.

Xu Yunjin asked the wild vegetables to be tasted by livestock and mice before the doctor checked whether they were poisonous, and finally issued a notice after confirming that there would be no adverse reactions after human consumption.

"Doctor Xian, this medical book was passed down to me by my mysterious master, and it contains a lot of herbs that are not in our current medical books.

Xu Yunjin took a thick medical book from Yuan San's hand, which summarized the names and medicinal properties of all the Chinese herbs currently known.

"Thank you county lord, the old man must use this medical book well."

Doctor Xian is the doctor who is looking for the medicine door, looking at his age, his eyes lit up when he looked at the medical book on Xu Yunjin's mobile phone.

Sure enough, the head didn't lie to me, the girl was really generous, and when she thought that she could see more plants she didn't know in the future, Dr. Xian held the book given by Xu Yunjin in her hand and regarded it as a treasure.

Xu Yunjin thought that the research institute could not only study whether those wild things could be eaten, but also study other functions of plants, such as untapped medicinal properties.

Xu Yunjin is very satisfied with today's trip, the research institute only got rapeseed on the first day, and it looks like there are still a lot, and you can try to extract oil after the harvest in September and October this year.

Fortunately, there is exactly one in the book system for oil extraction, otherwise this rape is also a white seed.

"Host, why don't you sprinkle all those seeds in your storehouse into the mountains, and then you can find a way to lead people to the mountains to find those crops, wouldn't it be the best of both worlds if you don't want to be overly noticed, and at the same time enrich the planting system?"

Xiao Yi felt Xu Yunjin's happy mood and reminded.

"yes, why didn't I think of it, Xiaoyi, you are so smart, you are simply my best helper."

Each upgrade of the system rewards seeds for one or two crops, and she still has three crops in her warehouse that are not available in this world.

The rest of the tomatoes, eggplants, and taro seeds that were rewarded during the upgrade were all planted by Xu Yunjin under various pretexts.

Now she has three kinds of vegetables there: carrots, pumpkins and cabbage, which can almost be planted at this time, and will be harvested in September and October.

And there is no shortage of seeds in the warehouse, when she sprinkles all over the mountain, the harvest will be more, and the seeds will be planted in large quantities next year, benefiting the people just around the corner.

Xu Yunjin couldn't stop giggling happily when he thought of that scene, and he was going to go to the mountains the next day to do it.

As soon as he got home and had dinner in the evening, Xu Yunjin called Old Man Xu and Xu Wu to the study to talk about it.

Since He Liguang's incident, Yuan San is now following her every step of the way except sleeping, washing, and going to the toilet, and she has to have someone to cover her if she wants to go up the mountain tomorrow.

"It's definitely not okay for you to go into the mountains alone, let your uncle go with you, and I can help you sow seeds together."

Old man Xu also expressed his support when he heard Xu Yunjin's plan, but now that the weather is starting to warm up, there are many snakes and insects in the mountains, so it is safer to have Xu Wu with him.

Xu Wu naturally had no opinion on following Xu Yunjin, and the next morning Xu Wu asked Xu Yunjin to go under the pretext that there was something in the soy sauce workshop, and successfully left Yuan San at home.

The uncle and nephew went all the way into the mountains from behind the workshop, and when they were about to enter the deep mountains, they found two flat lands with plenty of sunshine, flat and empty land, and the two began to dig pits and sprinkle seeds.

differ

After a while, the matter will be done, afraid that the birds will eat it if it is planted in the mountains, Xu Yunjin sprinkled a lot of seeds, and even sprinkled them while walking on the way back, and stopped halfway up the mountain.

It was just time for the uncle and nephew to go back for lunch, and Yuan San was still curious about whether he just went to the workshop, why was the girl's skirt and shoes so dirty, and the simple Yuan San was fooled by Xu Yunjin's words.

A few days later, Xu Yunjin received a letter from the capital, which was sent by Xu Wen, saying that Qi Ren was furious when he found out what the He family had done, and he was almost impulsive to confront He Yuanting.

In the end, Qi Ren ordered a secret investigation into the matter, and it was conservatively estimated that He Xiang's party would suffer a big loss in three months at most.

At this time, Yuan Xuan, who was about to return to Beijing, also came to the medical school, and at the same time brought bad news.

"What, the Northern Barbarians are attacking us again?"

As soon as Xu Yunjin heard the news, he immediately jumped up, and after meeting the border with the old general, he fought more than 30 battles with the Beiban one after another.

So far, the two sides have lost and won, and the last three cities of Daqi are still in the hands of the Beiman, and the two sides have been fighting since last year's ice and snow period.

"Last month, Beiban carried out several sneak attacks outside Dafang County, and I heard that the fifth prince of Beiban, Ha Ting, is also there this time, and he has a strategist by his side, and we have lost a lot of soldiers."

Speaking of Hating, Xu Yunjin was a little weak-hearted, she had cheated this prince, and if she was caught by him one day, she would not have to be skinned and cramped.

"I heard a report from the Beiban that after Ha Ting brought the fake prescription back, it was useless for the people of their tribe to eat it, and a lot of medicinal materials were wasted, and the important thing is that he was fooled into drinking the medicine with horse manure, and he realized that he was deceived Ha Ting was angry."

Yuan Xuan said this with a smile in his words, and he didn't know where this junior sister came up with so many ghost ideas at such a young age.

"Hahaha, whoever dares to invade my Daqi territory, it's light to eat horse manure."

Xu Yunjin couldn't help laughing out loud when she thought of the scene of drinking horse manure, if she had known that they hadn't tried that medicine in Chenyu County, she should have added a few herbs to it to let them pull their stomachs for seventeen or eighteen days.

"Hey, the old general Xiang is so old and still fighting for the country and the people, on the other hand, those corrupt officials are still doing well, when I think of this, I want to throw those people on the battlefield as human shields."

Xu Yunjin said angrily, Yuan Xuan was also silent and did not speak, and suddenly Xu Yunjin turned around and went back to the room.

After a long while, Xu Yunjin came out with a thick stack of paper in his hand, which was full of things that needed to be paid attention to in disinfection and emergency treatment, in addition to a thick medical book.

"That's how you gave this sewing technique?"

Yuan Xuan didn't speak for a long time after reading everything, and the generosity of her own junior sister was afraid that only she could do it.

"This thing is dead in the hand, and it can only be used if it is used in the right place."

For medical skills, Xu Yunjin has never been stingy, and she can brazenly say that everything else was discovered by their family.

Only medical skills, Xu Yunjin always has a sense of awe, and he doesn't want to use the hard work of his predecessors to put gold on his face.

"I thank you on behalf of the soldiers at the border."

Yuan Xuan put down the book and solemnly thanked Xu Yunjin, but Xu Yunjin was startled, and the senior brother and sister looked at each other and laughed again.

Yuan Xuan left early in the morning of the third day, and when he came, there were only a few people, but when he returned, he was followed by more than a dozen carriages.

The first few trucks were full of alcohol, and the back was all the existing stock of soy products in the tofu factory, and a batch of soap was sent to the barracks for the soldiers to wash and eat.

This was donated by Xu Yunjin to the soldiers at the border pass on behalf of the Xu family, and the carriage went all the way out of Jiujiang Mansion City and received a lot of attention.

As soon as the curious people inquired about the materials donated by the Xu family, they immediately had the impression of the Xu family, and they had grown a lot taller.
