"Uncle, when will my father and mother come back?" In the back garden of Zhao Yan's courtyard, Shu'er, who was about to be eight years old, picked up Zhao Yan's chair and asked with wide eyes, he hadn't seen his parents for more than a year, so he naturally missed him very much, so he had to pester Zhao Yan every few days to ask.

"This ...... It should be soon, maybe I'll be back after the New Year. Zhao Yan replied with some weakness, Princess Dening could have come back earlier, but this time to negotiate with Jiaozhi, Zhao Yan recommended Princess Dening and his wife, but Zhao Shu really agreed, and now the holy decree has been sent to Guangzhou, it is estimated that Princess Dening and her husband and wife may not be able to come back in a short time.

"Really, uncle, you won't lie to me, will you?" Although Shu'er was young, she was very precocious, and she immediately heard the weakness in Zhao Yan's tone, so she asked very suspiciously at this time.

"Cough~" Looking at Shu'er's big eyes full of suspicion, Zhao Yan couldn't bear to lie to him again, and said honestly with a dry cough at the moment, "Shu'er, your parents have very important things to do in Guangzhou, so they can't come back for the time being, but it doesn't matter, you will celebrate the New Year with your uncle this year, and Siyue and them will accompany you, which will definitely be more lively than you at home!" ”

Hearing that his parents couldn't come back for the time being, Shu'er's face couldn't help but show a look of disappointment, but he was also very sensible, and he didn't cry or lose his temper because of this, but thought for a moment and asked again: "Uncle, my father and mother can't come back this year, so can they come back next year?" ”

"You can definitely come back, if they don't come back by then, then your uncle will personally take you to Guangzhou to find them!" When Zhao Yan heard this, he immediately patted his chest and assured that although the negotiation with Jiaozhi would take some time, it would definitely not take a year, so Zhao Yan dared to guarantee Shu'er like this.

Seeing Zhao Yan's sworn appearance. Shu'er finally stopped doubting his words, and although his parents were not around, his aunt and uncle were very good to him, and he usually had to go to school again, and he would not feel lonely with his school friends with him. So Shu'er quickly put her parents' affairs aside.

"Huh? By the way, why didn't you go to school? Zhao Yan suddenly thought that today didn't seem to be the tenth day, Ouyang Wanling and Yan Yuru went to the girls' school early in the morning, and it was said that Shu'er should also go to school to attend classes.

"Giggles, I know what the school teachers teach, and I am the first in every exam, so it's the same whether I listen or not, it's better to learn more things with my uncle." Shu'er smiled mischievously, what he said was also the truth. Originally, he was a child with a superior IQ, and Zhao Yan opened a small stove for him, but the content taught in primary school was not difficult for him at all, and even he had finished studying the textbooks in primary school by himself, if he participated in the entrance examination of Gewu Academy this year, he would definitely be able to get in.

"That's not right, didn't I tell you that you didn't just go to elementary school just to study. It is more important to learn to communicate with people, and to want to communicate with people. The most important thing is not to specialize yourself, otherwise you won't make any friends! Zhao Yan heard this but reprimanded with a straight face, although he usually likes Shu'er very much, but if the other party makes a mistake, he will not hesitate to criticize, after all, he regards Shu'er as his personal disciple. Of course, you can't just watch him make mistakes.

"Hehe, I knew my uncle would say that, but I didn't have any problems communicating with people, and the rest of the class liked me very much, and we were all very good friends. And the reason why I didn't go to class this time was because I had an important thing to do! Shu'er heard Zhao Yan's criticism, first smiled cheekily, and then defended himself seriously.

"Oh? What can you do that matters? Zhao Yan asked in surprise when he heard this.

"Of course there are important things, I helped the second aunt build a glass greenhouse before, and now the weather is too cold, so I moved all the flowers and plants she raised to the greenhouse, but in the past few days, there have been problems with the flowers and plants in those greenhouses, so I asked for leave to help the second aunt cure those flowers and plants!" Shu'er explained to herself that the second aunt in his mouth naturally refers to Princess Bao'an, Princess Bao'an usually likes to raise some flowers and plants, but flowers and plants will inevitably wither in winter, so Zhao Yan helped her build a glass greenhouse, and every winter, Princess Bao'an will move flowers and plants to the greenhouse.

"Then why don't you go to the second sister?" Zhao Yan opened his mouth and asked, and then he understood, and then he suddenly smiled, "I understand, you must have gone to see the problem of those flowers and plants, but you couldn't solve it, that's why you came to me, right?" ”

"Hehe, uncle is wise, I can't hide anything from you!" Shu'er said with a hippie smile again, he learned a lot of interesting knowledge from Zhao Yan, but some aspects are still much worse, such as this time Princess Bao'an encountered the problem of flowers and plants, he couldn't think of a solution for a long time.

"Tell me, what's wrong with the second sister's flowers and plants, and it stumped you, a little genius?" Zhao Yan couldn't help but laugh again when he heard this, people have emotional needs, especially after leaving empty, Princess Bao'an pinned her feelings on those flowers and plants, and usually paid great attention to the flowers and plants she raised, last time Zhao Yan went to her and accidentally stepped on a peony, but she was said for a long time, and now there is a problem with those flowers and plants, Princess Bao'an must be very anxious.

"I can't say this clearly, uncle, you better go and take a look." Shu'er said and took Zhao Yan's hand and ran to the courtyard where Princess Bao'an lived, Zhao Yan was also worried that Princess Bao'an would be sad, so he followed Shu'er to the courtyard where Princess Bao'an lived.

It is already the middle of winter, if you come to the courtyard where Princess Bao'an lives in summer and autumn, you will see that the yard is full of lush flowers and plants, most of which are not precious, but they are very carefully taken care of by Princess Bao'an, and they are also very lush, but now the flowers and plants in the yard have been transplanted to the glass greenhouse on the east side of the yard, today's sun is very good, and the mat outside the glass greenhouse has been opened, revealing the green inside the ground.

"Third sister, why are you here?" As soon as Zhao Yan entered the greenhouse, he immediately saw Princess Shoukang standing among a bunch of flowers and plants with a small flower hoe in her hand, and her face also showed a rare sad look.

"It's not the second sister's precious flowers and plants that make trouble, you see that these flowers and plants used to grow well, but now they seem to be sick, and some of the second sisters are about to cry in a hurry." Princess Shoukang sighed and pointed to the flowers and plants in front of her.

Zhao Yan only found out at this time that although the flowers and plants in the greenhouse looked green, a considerable part of the flowers and plants had irregular yellow spots on the leaves, and some of them were even connected, making the leaves completely yellow, which looked very ugly, and some of the leaves had white mildew, like a clump of spider webs.

"Why are all these flowers and plants sick?" Zhao Yan was in the countryside when he was teaching in his previous life, and he was relatively familiar with crops, so he could see at a glance that these flowers and plants were sick because of this situation.

"I don't know, the second sister said that it was fine a few days ago, but slowly these yellow spots appeared on the leaves of these flowers and plants, and at first it was only one or two, but slowly the flowers and plants in the entire greenhouse were infected." Princess Shoukang sighed again at this time.

"What about the second sister, why didn't you see her?" Zhao Yan suddenly found that Princess Bao'an was not here at this time, and asked very strangely at the moment, according to Princess Bao'an's love for these flowers and plants, she should stay here now.

"The second sister went to Sinong Temple, saying that she wanted to invite someone who understands this aspect to take a look, maybe there is a way to cure these flowers and plants." Princess Shoukang immediately replied that Sinong Temple was in charge of grain storage, warehouse management, and the supply of rice to the officials of the Beijing Dynasty, and the palaces and gardens in various parts of the palace were also under their management, and all kinds of rare flowers and plants were planted in the palace, so they had special talents responsible for the pests and diseases of flowers and plants.

Zhao Yan nodded when he heard this, and then began to carefully observe the flowers and plants in the greenhouse, although he had never planted the land, but he benefited from the education he received in his previous life, coupled with the experience of teaching, so that he also had some understanding of plant pests and diseases, and even knew the ingredients of some pesticides, so he wanted to try to find out the cause of these flowers and plants, and then find a way to cure them.

Zhao Yan observed for a while, and finally determined that these flowers and plants should have some kind of downy mildew, which is caused by a fungus, such as those spider-like things on the leaves, which are actually fungal hyphae, this kind of downy mildew is also a very common disease of plants, and once it breaks out, it is likely to cause damage to plants.

After figuring out the cause of these flowers and plants, Zhao Yan finally breathed a sigh of relief, what he was most afraid of was that these flowers and plants had diseases that he didn't know, so if he wanted to be treated, he could only try his luck, and if he didn't do it well, he would cure these flowers and plants to death, but now that he knows the cause, he can carry out targeted treatment.

"Third brother, you've been here for a long time, is there a way to treat these flowers and plants?" At this time, Princess Shoukang suddenly came over and asked, she knew that Zhao Yan knew a lot of strange knowledge, maybe there would be a way to treat these flowers and plants.

"This ...... Hehe, keep it secret for the time being, third sister, you are busy first, I'll go and prepare! Zhao Yan deliberately sold a pass, and then ran out with Shu'er, but stomped Princess Shoukang angrily, threw away the flower hoe in his hand and sat in the greenhouse sulking. (To be continued......)
