Outside the kitchen, there was a gust of cold wind and snowflakes, but there was a hot scene in the kitchen. There were a large pot sitting on several coal stoves, and there were many bottles and jars in the cage in the pot. As the heat swelled, the aroma of food was emitting, making people unable to help but breathe.

"Are these what you call canned food?" Princess Pingyang asked curiously as she looked at the bottles and jars in the pot. After walking around a few times outside, Li Xiu took her to her home and said that she would see a food called canned food. But now it seems that the so-called canned food is not magical. It seems that it just put the food in the jar and steamed it?

"Haha, this is just a semi-finished product, and there will be some processing next to you." Li Xiu said as he signaled Yue Chan next to him to continue, so he saw Yue Chan take out a cork from another boiling pot, then gently put it on the mouth of the jar, and then covered the pot and steamed it hard. After waiting for about half an hour, Yue Chan opened the lid, and then used a special thick wooden stick to compact the cork on the jar, and finally took out the jar.

"Okay, these can be called canned now!" Li Xiu smiled and put on a thick glove, then picked up a jar and admired it carefully. Unfortunately, there was no glass, so he used all ceramic jars, and he couldn't see the food inside. It was not difficult to make canned food, but the difficulty was to find these ceramic jars. In order to find suitable and easy-to-seal ceramic jars, Li Xiu also went to Chang'an and went to many ceramic shops. It was difficult to find so many.

"But what's the use? Is it just for the convenience of putting the food in the jar?" Princess Pingyang said with a confused look on her face. She really couldn't figure out what Li Xiu was trying to do this?

"Haha~, of course, the function of canned food is not like this. The kitchen is too busy, so let's not stand here to block the way. Yuechan and the others have to produce more canned food for experiments. Let's go outside to talk!" Li Xiu smiled again when he heard this, and then went out to the kitchen with Princess Pingyang.

At that moment, Li Xiu took Princess Pingyang to the front hall to sit down. At this time, he was holding a canned freshly made. While the food inside was still hot, Li Xiu plugged the cork on it, and then handed it to Princess Pingyang and smiled: "How does the princess taste this canned food? It's the mutton made by Yuechan himself, which is delicious."

Seeing that Li Xiu was not in a hurry to explain the canned food, she let herself taste the canned food, which made Princess Pingyang feel a little anxious. However, she was a very patient person. She took the canned food without using chopsticks and picked up a piece of mutton with her fingers and put it in her mouth. As a result, the mutton was made of plump and juicy, and it was indeed very delicious.

"It's really delicious. Can this can make the food delicious?" Princess Pingyang asked again strangely. It seemed that she would not be willing to do so without understanding the function of canning.

"Haha, canned food is actually a way to preserve food and cannot make food delicious, but it can preserve the delicious food for a longer time. For example, the canned food that the princess eats now has this taste. After it can be preserved in canned food, then one month, two months, or even half a year to a year later, its taste still remains unchanged and the food will not rot, just like it was just made." Li Xiu explained with a smile.

The original canned food made under the current simple conditions cannot be preserved for many years like those of the iron cans in later generations, but he is still confident that he can keep it for half a year to a year. With this period of buffering, he can transport the easily deteriorated food to the places where he needs it. This is the biggest function of canned food.

"You... are you kidding. How can the mutton in cans last for half a year or a year, unless it is kept frozen in the ice in winter, but it is as hot as summer, and it may turn bad and cannot be eaten in one or two days." Princess Pingyang said in disbelief when she heard this. Li Xiu's words once again broke her understanding of the world, so she was unable to accept it for a while.

"The princess doesn't have to doubt this. This is the magic of canned food. The reason why food deteriorates is because something we can't see is causing trouble. You can regard them as a kind of poison. I just put the can in a pot and steam it to eliminate this poison and then seal it up. In this way, the poison from the outside cannot be in, and naturally the food inside will not change!" Li Xiu explained the principle of canned food in a word that Princess Pingyang could understand.

"How can there be poison in food? If the food we usually eat is poisonous, will it have an impact on our bodies?" Princess Pingyang understood Li Xiu's explanation, but soon a second question arose. After all, she didn't know what microorganisms were.

"This..." Li Xiu didn't know how to explain this for a while. If he started from the beginning, he didn't know whether Princess Pingyang could accept the concept of microorganisms. And if he wanted to explain the microorganisms clearly, he didn't know how much time it would take?

But at this moment, Xiao Dong, who was guarding the door, suddenly came to report in panic: "Master Qi, there were many people coming outside, and the old man was very unreasonable, so he pushed open the door and broke in!"

Just as Xiaodong finished speaking, a man with a white head and a mighty appearance strode into the hall. Li Xiu's first impression when he saw the other person was a little familiar. However, before he could remember the other person's identity, Princess Pingyang stood up with a red face and saluted, "My son-in-law, pay homage to my father!"

When Li Xiu heard Princess Pingyang's words, he finally remembered that during the Lantern Festival this year, he had seen each other in the Princess Villa. This mighty man was Li Yuan, the emperor of the Tang Dynasty. However, he hadn't seen him for nearly a year, but he had a lot of white hair on his head, which looked much older than before.

"I am here to see Your Majesty!" Li Xiu also hurriedly saluted at this time. As for Xiao Dong next to him, he almost fainted. She just called the other party an unreasonable old man, but she didn't expect that he was the Emperor of the Tang Dynasty.

Seeing Xiaodong's fear, Li Xiu hurriedly pulled her, let her hide behind him, and then saluted Li Yuan again and said, "Just just now, the servant didn't know His Majesty's face and collided with the Holy Lord. I hope Your Majesty won't blame him!"

"Hmph, I'm not that stingy yet, let's go down!" Li Yuan looked around, then waved his sleeves unhappily and said, "He came to find his daughter Pingyang in the snow, wanting to talk to her well, but he didn't expect that Pingyang was picked up by Li Xiu first, making him lose everything, which made Li Yuan a little angry, and he immediately found Li Xiu's house.

Hearing Li Yuan's words, Li Xiu couldn't help but breathe a sigh of relief. He waved to Xiao Dong, who had not yet reacted. The girl finally understood and ran away from the living room. Then an imperial guard surrounded the living room and prohibited anyone from entering.

"Pingyang, how are you doing recently? Have you recovered from your old injuries?" After everyone stepped down, Li Yuan smiled gently to Princess Pingyang, then sat down on his own, and left Li Xiu, the master, aside.

"My daughter is very good. How could the father have time to leave the city today? And it is snowing outside. The father should take care of his health!" Princess Pingyang replied immediately. Last time, because of Chai Shao's incident, the father and daughter had a little unhappy relationship, but there was no deep hatred between the father and daughter? So when Princess Pingyang saw Li Yuan again, she was also very concerned about his health.

"Haha, fortunately, Pingyang, you care about your father's body. Unlike your elder brother and your second brother, who fight for a little power all day long, regardless of the feeling of being a father!" Li Xiu said at the end, his face also showed a look of annoyance. After seeing his daughter's filial look, he became even more angry with Li Jiancheng and Li Shimin.

When Li Xiu heard this, he secretly curled his lips and disagreed with Li Yuan's words. Is it because Li Yuan himself did not handle it well? It can even be said that the root of this matter lies in Li Yuan, but now he actually blames his two sons and is really good at shirking responsibility.

"The eldest brother and the second brother also have their own difficulties and ideas, so don't be too angry with them." Princess Pingyang advised again at this time, but after persuading, she could not express any opinion on this matter, because no matter which one she favored, she would feel ashamed of the other. From this point of view, she was in the same situation as Li Yuan. No wonder Li Yuan came to her to talk to her, because only Princess Pingyang could better understand his situation of being embarrassed on both sides.

"Oh, now your elder brother and second brother are having such a fuss. I really miss your mother. If she was still alive, I would probably not have to make things so difficult for me!" Li Yuan confided to his daughter again. As for Li Xiu next to him, he regarded him as a transparent person, or he didn't care that Li Xiu heard these words at all.

When Princess Pingyang heard her father mention her mother, she couldn't help but show a sad look, but she couldn't be resurrected. As a daughter, she felt it was necessary to share her worries for her father, so she gritted her teeth and said, "The father doesn't have to be too embarrassed. If it really doesn't work, it's better for her daughter to come forward and persuade her elder brother and second brother, so as not to make a big fuss."

As Princess Pingyang, who has never interfered in the battle between the two brothers, being able to say the above is considered a huge sacrifice. However, after hearing this, Li Yuan shook it, and then looked at Princess Pingyang with some indulgence and said, "No need, you are in the same situation as your father, and you have always ignored this matter, so don't get involved!"

Li Yuan said this and didn't want Princess Pingyang to say anything anymore. He smiled and changed the topic: "Pingyang, you don't stay at home in such a cold weather. What should you do if you get cold? What if you get sick?" (To be continued.)8
