The days flew by, and if it weren't for the chance glimpse of the tree that suddenly lost a leaf at some point, Xia Hongsheng would not have realized that the season had gone from summer to late autumn.

Everything seems to be uneventful, and the biggest movement seems to be that the Normal College expelled several students for their misdeeds during their time at school. Although Xia Hongsheng meant that they should be given a chance to make amends, this time they should be warned, and they would be expelled if they committed another offense. But the other chairs and gentlemen have a tough attitude and do not tolerate the slightest flaw. It said that the Normal Academy is different from Jingyang Academy, Jingyang Academy teaches students, while Normal College teaches students, so it must have higher standards and stricter requirements.

For the insistence of the chairs and gentlemen, Xia Hongsheng was helpless.

Other than that, there really doesn't seem to be anything special. But Xia Hongsheng knew that this was just the calm before the storm.

In this huge empire, all the resources are now prioritized in preparing for the conquest of the Great Eat.

This shows the advantages of centralization. When the imperial court decides something, it has the ability to concentrate all its superior resources in favor of it.

In the blink of an eye, March has passed, and Xia Hongsheng also took the batch of cans he tried to make and opened some of them.

The vegetables inside still have a crisp and tender texture, and the fruits are still sweet and tender. The cooked meat is not spoiled, but has a different flavor.

Look at the condition of the contents of the can, if you don't open it, you will probably have no problem leaving it for another three months.

That's success.

However, Xia Hongsheng was not in a hurry, but waited for another two months, and when it was completely winter and everything was gone, he filled a lot of cans with several cans, put them on the carriage, and took them to Chang'an.

Inside the palace, Li Shimin is snuggling up to the kotatsu - in winter, Xia Hongsheng installed a combination of kang and tatami mats in his study, because there is no electric heater, and the charcoal stove is too dangerous, so Xia Hongsheng made a fire kang, and the kang was made into a tatami mat in the house, so that there is not only the safety, convenience and warmth of the ondol, but also the comfort and beauty of the tatami mat - with the kotatsu, naturally we can't forget to honor the two fathers-in-law, so I also made it for them.

"Hehe, how can the virtuous son-in-law be willing to come out of the academy today?" When Li Shimin saw Xia Hongsheng, he said with a smile, and then said to his daughter: "Changle, come and sit here, it's so warm here." ”

"Father, it's too warm here, and the windows are closed so tightly, so if you go out, it's easy to get cold!" Li Lizhi said as she went over and opened a gap in the window to let in some air outside.

The two sat down and chatted with Li Shimin for a while, and Li Shimin said to Li Li: "Go and see your mother, and your sister-in-law, she can pester your mother all day long, just like when you were young." ”

"Father, the daughter will go to find the queen mother!" Li Li said goodbye and went to find the eldest grandson.

After Li Lizhi left, Li Shimin turned to Xia Hongsheng and asked, "I heard that you have made a lot of preparations, how are you preparing now?" ”

Xia Hongsheng knew that Li Shimin's question was his preparation for leaving for Dashi, so he smiled and said: "Fortunately, the Taiyi Bureau has provided a lot of medicinal materials, and I have found many patients in Chang'an City to try out the granule powder, and the results are good." Although the potion has been reduced somewhat, it is almost negligible. Patients don't have to go back to bother boiling, they only need to pour the granules into warm water and stir a few times when drinking the medicine, and then they can drink it, and the effect is basically the same as the boiled medicinal juice. At present, we have begun to make a large number of granules required for various diseases. However, the production capacity is somewhat insufficient, and the production is far from enough to be used for the expedition. ”

"Since it does not affect the efficacy of the medicine, it is so convenient to carry in large quantities, and it is more convenient to drink, so I will make it in large quantities." Li Shimin said: "With this thing, there is no need to worry about the soldiers in the army getting sick and the medicine is not enough. This is another great achievement of a virtuous son-in-law. ”

"No, this is a method that those people in the academy who majored in medicine came up with." Xia Hongsheng shook his head and said, "Thanks to Imperial Doctor He, he is willing to let the Imperial Medical Bureau cooperate with the medical profession of the academy. ”

Li Shimin stared at Xia Hongsheng, as if he had seen through his thoughts, smiled, and said, "Okay!" In this case, I should take this credit for dedicating this method to the medical major of the college, and attribute this credit to the medical major of the college. ”

Xia Hongsheng smiled again: "My son-in-law came today and brought some food for my father-in-law." Just put it outside. ”

"Oh?" Li Shimin was very interested: "Why don't you just bring it in-Wang De, go and get it." ”

Wang De commanded, went outside the hall, took the box brought by Xia Hongsheng in and opened it, took out the cans of canned food inside, and put them in front of Li Shimin. The tray and chopsticks were already in the box, and they were taken out as well.

Li Shimin looked at the canned food in front of him and said with a smile: "The green vegetables in the virtuous son-in-law's greenhouse are ripe - heh, the virtuous son-in-law also planted plums!" ”

Xia Hongsheng smiled and said nothing, just reached out and took a bottle of canned green plums, unscrewed the lid vigorously, and then used chopsticks to take out the plums inside, put them in the plate, and put the plate in front of Li Shimin, and put another pair of chopsticks on it.

Li Shimin picked up the chopsticks, picked up the green plum in the plate, took a bite, couldn't help but be surprised, looked up and said, "En!" Sweet and sour! ”

"Father-in-law, you're trying this." Xia Hongsheng opened a can and took out a piece of cucumber from it.

Li Shimin picked it up and took a bite: "Yes, it's crisp and tight." Eat it too! ”

Xia Hongsheng unscrewed other cans one after another, and accompanied Li Shimin to taste them one by one, Li Shimin tasted them separately, and said: "This greenhouse is really a good thing, don't talk about the people in the past, it is me, if you want to taste a mouthful of green vegetables in this winter, it is not very rare." Nowadays, people also have cheap green vegetables to eat in winter. ”

Xia Hongsheng still smiled and said nothing, took out another canned beef, opened it and took out a piece for Li Shimin.

"This meat ......" Li Shimin was a little puzzled when he saw that it was not a green vegetable, but he still picked up the meat, tasted it, and said: "Well, it's good, it's soft and delicious, salty and delicious!" ”

"Father-in-law, you don't know that all these things you tasted today did not come out of the greenhouse." Xia Hongsheng also took a bite of beef and said while eating.

"Huh?" Li Shimin looked down at these things in front of him, and asked: "If it doesn't come out of the greenhouse, in addition to the hot spring, where can you grow green vegetables in winter?" ”

"Naturally, it's not next to hot springs." Xia Hongsheng smiled mysteriously.
