"Naturally, it's not next to a hot spring." Xia Hongsheng smiled mysteriously and said to Li Shimin: "To be exact, these things are not planted right now. ”

"Then how can you get such fresh greens?" Li Shimin was even more curious.

Xia Hongsheng replied with a smile: "It's good to teach my father-in-law to know that these things are actually saved when they are in season." ”

Xia Hongsheng pointed to the can in front of Li Shimin and said, "It's like this bottle of cucumber, which was picked in July." And this bottle of plums, also from that time. This can of beef has also been more than four months old. These things were all made by the son-in-law four months ago, and it was only today that he came to eat. ”

"What?!" Li Shimin looked down at the green vegetables in front of him in shock.

He stretched out his chopsticks, picked up half of the cucumber, looked left and right, and bit it with his upper teeth, and it was really crisp, and he couldn't help but be even more surprised.

"This ...... More than four months...... How did the virtuous son-in-law let these green vegetables sit for more than four months, but they were still so tender? Li Shimin raised his head and asked.

"It's a way to store food, fruits and vegetables." Xia Hongsheng said: "These things are called canned food. Vegetables, fruits, meat and other foods that cannot be stored for a long time, fruits and vegetables, after cooking, put them in a wide-mouth glass bottle, and then fumigate them with hot steam, after half an hour, seal the bottle while it is hot, and then wrap it with a prepared thin wire while it is hot, and then wrap it with a layer of wax to ensure that it is sealed, and then let it cool naturally. In this way, the food, fruits and vegetables can be preserved for a long time, even in the past six months, when they are opened and eaten, they can still retain their tender taste, and naturally they can also preserve the nutrients contained in these foods, fruits and vegetables. ”

Li Shimin's eyes froze, and he immediately raised his head, took his eyes away from those green vegetables, and stared at Xia Hongsheng.

Xia Hongsheng took out the contents of the can and put it on the plate in front of Li Shimin, and continued: "The sailor wants to go to Dashi, even if he can get supplies from Basein, but because he wants to block the sea route, encircle Dashi at sea, and eliminate Dashi's sailor, he needs to cruise on the sea far away from the harbor for a long time. In addition, the temperature and humidity are high, so even if there is a large amount of food on the ship, it is easy to spoil, not to mention vegetables and fruits. ”

"Vegetables and fruits are as important to the human body as food. If you don't eat vegetables and fruits for a long time, your body will lack many things that you need to maintain your health. Xia Hongsheng said: "When sailing in the ocean, the most feared thing is malnutrition. If people on board are short of vegetables and fruits for a long time, they are very susceptible to a large number of diseases called sepsis. Once you get this disease, in terms of our medical skills today, it is a mortal disease. This is also the most important reason why they will travel long distances and die for a lifetime. ”

"To prevent it, you need to eat vegetables and fruits. However, vegetables and fruits are often highly perishable and cannot be carried in large quantities over long distances. Xia Hongsheng said: "And with this thing, this problem has been solved." ”

"Can this thing really keep those fruits and vegetables for half a year?" Li Shimin's eyes were solemn and he asked in a deep voice.

Xia Hongsheng nodded solemnly and replied, "The son-in-law doesn't dare to speak." These canned foods were all made and put away by the son-in-law more than four months ago. When I opened it today, there was no trace of the contents that were going to rot and deteriorate. Depending on the condition, if it is not opened, there will be no problem if it is left for another three or four months. ”

"The color is indeed fresh and tender, as if it were freshly picked." Li Shimin looked at the contents of the can and said.

"It's not just the Sailors. These cans can also be used as a supplement to military rations in the land army. Xia Hongsheng said: "People need vitamins provided by vegetables and fruits to ensure the health of the body, the army has traveled a long distance, if you can get these vegetables and fruits in addition to eating military rations, it is not only good for the body, so that the body is healthier, play a better combat effectiveness, and can improve the food, so that the soldiers are in a good mood when eating, and the morale of the army also has a better effect." ”

Li Shimin was born in the military, how can he not understand the benefits of this thing for the army. Datang is not unable to afford the grain and grass in the army, it is precisely because vegetables cannot be preserved for a long time, so although the grain and grass in the army are sufficient, there are still no vegetables to eat, and even meat can only be made into cured meat and bacon, all in order to be able to preserve it for a long time. And with this thing in front of you, none of this is a problem.

"It's a good thing!" Li Shimin patted the small table, and suddenly asked, "How much is the virtuous son-in-law going to sell?" ”

"These all depend on the cost, some fruits and vegetables are easy to obtain, some fruits and vegetables are rare, the process of making them is not the same, the cost is different, but in general, vegetables and fruits are cheaper, meat is definitely more expensive, but pork is not very expensive, but beef is definitely the most expensive...... Uh-uh! Father-in-law......" As he spoke, Xia Hongsheng suddenly reacted, and immediately laughed and stopped talking.

"Smack!" Li Shimin slapped the table heavily and shouted, "You kid really has the idea of picking money from the imperial court!" ”

"This ...... Father-in-law, son-in-law is poor! Xia Hongsheng hurriedly cried poorly: "The son-in-law undertook the construction of the railway, and the things studied in the scientific research institute are all funded and supported by the son-in-law, and there are also academies, and some schools in Jingyang are being built...... The son-in-law's house can't open the pot! ”

"I have already handed over the bicycle to you, and the imperial court and the military aircraft workshop have nothing to occupy, what do you want?!" Li Shimin snorted and said.

"Oh, the son-in-law is grateful for the kindness of his father-in-law, so if these cans are purchased by the court for use in the army, the son-in-law will only charge the cost." Xia Hongsheng hurriedly said: "As for the sale to the people, the son-in-law will not be too expensive, the main thing is to let the people afford to eat, because the cost of canned food is lower than the cost of planting greenhouses, so it must be much cheaper to sell in winter than the green vegetables grown in the greenhouse, and ordinary people can also have fresh and tender green vegetables to eat in winter." ”

"Do you believe it or not, I will go down, your method of making canned food, even if you don't need a penny, you have to give it to the court?" Li Shimin sneered and stared at Xia Hongsheng and said.

"Father-in-law, you are both agriculturally and commercially, and now you are wisely developing business, and you will definitely not do this." Xia Hongsheng smiled very firmly.

Li Shimin stared at Xia Hongsheng angrily, with a hint of gnashing his teeth, and after a while, he shouted at Xia Hongsheng: "Get out!" Get out of here! I don't want to see you again these days! When the sailor sets out, if you can't make enough canned food, I will beat you with 200 court rods first! ”

"Hey, yes, make sure you're done! The son-in-law will arrange it. Xia Hongsheng knew that Li Shimin had agreed, and said with a smile: "My son-in-law will come to pick up Her Royal Highness the princess in a few days." ”
