As soon as Li Shimin entered the East Palace, within a while, all the ministers also rushed to meet with Li Shimin, Empress Changsun and others.

At this time, Li Chengqian stood in front of Li Shimin.

Sun Simiao is also among them.

First of all, Li Shimin asked: "Gao Ming, when will this vegetable be served?" ”

Li Shimin couldn't wait any longer, his mouth was lonely, and he wanted to eat fresh vegetables.

Li Chengqian still looks unhurried.

"Your Majesty is at ease, and the sons will let people serve the food."

But he thought in his heart, what are you anxious about, it will definitely open your eyes in a while!

After that, there were little yellow doors, and they began to serve dishes one by one. They are like waiters in a restaurant, even the plates have lids.

People are curious, why is the lid inside?

It wasn't until the lid was lifted that people knew what was on it.

One of the first dishes is braised eggplant.

The aroma of eggplant surrounds the entire East Palace. It made people swallow their saliva.

This is a dish that is not available in winter, and even if it does, it is only saved after the autumn harvest, so it will not last so long.

As soon as the dish was served, Fang Xuanling first said: "I didn't expect that in this winter, I can still eat eggplant!" ”

That touching look also infected other people.

Eggplant is not eaten all year round, and now it seems that it is possible.

Du Ruhui also said: "Yes, His Royal Highness the Crown Prince has great talents, and the way he thought of was to use the light transmission of glass to introduce light into the greenhouse, and then heat and heat the greenhouse, and when the temperature of growth is reached, it is simply to create a growth environment!" ”

Just now, Li Chengqian had already told them the principle, and people suddenly realized that this was the case.

Li Jing also said: "These out-of-season vegetables look very tempting, I don't know how it feels to eat? ”

After speaking, the saliva flowed.

"In my opinion, Lao Cheng, why don't you take a bite first? Isn't that what you know? ”

After saying that, Cheng bit the gold and didn't wait for Li Shimin to start, he had already swallowed half a plate of eggplant.

Then he said, "Well, this eggplant burns well!" Very tasteful! Tastes great! ”

And so, it's gone.

It made everyone extremely depressed. It's a waste to give him something to eat!

But when it comes to the anti-season, some people can't sit still at this time.

This person is Xiao Yu is also.

He stood up and said, "Your Majesty, the minister has a word, and I don't know whether to say it or not. ”

Most of what he said at this time was also unfavorable to Li Chengqian.

Since he wanted to say it, Li Shimin had to let him say it, and if he said anything, this guy could be regarded as a founding hero.

So he said: "Xiao Yu, what insights do you have, you can talk about it." Let's hear it! ”

"Confucius said: Eat the button and eat, the fish is hungry and the meat is rotten, and do not eat. Lust is evil, and he does not eat. Stink, don't eat. Lose food, don't eat. From time to time, do not eat. If you don't cut it right, you don't eat. Don't eat it, don't eat it. Selling wine in the market, not eating. ”

Xiao Yu is talking about Confucius's famous "eight non-eating" theory, which contains a very advanced concept of food, not fresh, discolored and flavorful things can not be eaten, improper cooking such as burnt things can not be eaten, out-of-season vegetables and fruits can not be eaten, three meals should be timed, some unsuitable parts of animals can not be eaten, and things bought at unhygienic stalls in the market cannot be eaten, which is very particular.

Your Majesty, Confucius has already made an incisive statement on this: "Among them: from time to time, do not eat." In other words, don't eat dishes that don't fit the season. And His Royal Highness the Crown Prince actually did the opposite, and the minister thought that this might not be good. And in this way, the expenditure is very large, let the people know, there is a fear that it will be detrimental to the people! ”

Xiao Yu said it is really reasonable, and it is impossible to refute it.

But when he heard these words in Li Chengqian's ears, he faced them with a smile.

In his time, out-of-season fruits and vegetables, not the same as eating?

I have never seen people eat to death, and the people of Confucius's time are still unknown to these things, so of course it is better to touch them less.

In fact, as early as the Qin and Han dynasties, out-of-season vegetables appeared.

The Book of Han: The Biography of Zhao Xinchen clearly records the fact that the ancients ate out-of-season vegetables. Zhao Xinchen was a well-known law-abiding official (follower) at that time, and at that time, the royal vegetable special supply base "Taiguanyuan" planted out-of-season vegetables, and the annual expenditure was very large.

Zhao Xinchen suggested not to do this: "Taiguan Garden is planted with winter onions and leeks, covered with roofs, burning fires day and night, and waiting for warmth to be born." The faithful thought that this was an occasional thing, and that it was not suitable to be offered to others, but that it was illegal food, and that it would save tens of millions of years. ”

"Yunhuo" is a flameless combustion method, the purpose of which is to warm the room and facilitate the growth of vegetables. Zhao Xinchen called out-of-season vegetables "illegal food" and could not be eaten, which was obviously a big deception, and its real purpose was to persuade the royal family not to be too extravagant. However, the production and supply of out-of-season vegetables for the royal family did not stop during the Han Dynasty.

Until the Tang Dynasty, people still rarely touched this greenhouse vegetable. It's also because the cost is too high, and the output can't keep up. And no one did it.

Even if there is, it is not as advanced as Li Chengqian, and it is directly produced by glass, and the varieties produced are very numerous, which is attractive.

Li Chengqian has already figured out how to refute Xiao Yu's.

This has to be refuted little by little.

What Xiao Yu said made everyone fall into contemplation, because it was justified.

"Gao Ming, what do you think?"

What Li Shimin asked is also what everyone wants to know.

"Your Majesty, the retainer wants to refute!"

"Oh?"

Li Chengqian's retort was very relaxed.

He did the opposite, and first said: "The two points mentioned by Song Guogong, the first point, this king will not say anything first, and will talk about it later, and the second point is simply unreasonable!" ”

As soon as these words came out, Xiao Yu's face turned red, what? Vexatious?

What do you say, you are also an old minister of the two dynasties, and you still have some kinship with Li Yuan.

Xiao Yu's wife is Queen Dugu's maiden niece. Li Yuan is the nephew of Queen Dugu, and Li Yuan and Xiao Yu's wife are uncles and cousins. Back then, when the two were officials in the Sui Dynasty together. Very good friendliness. When Li Shimin led his troops to attack Xue Ju, Xiao Yu and his wife Dugu set up a family banquet to entertain them. During the banquet, Li Shimin also respectfully called Xiao Yu and his wife cousins and uncles.

With such a kinship, what he said would make people dare not despise him, but now, he was said by Li Chengqian to be unreasonable.

But if Xiao Yu's wife is abandoned, he and Li Shimin are not related by blood.

was scolded by Li Chengqian, so he had to suppress his breath and say, "I don't know what His Royal Highness the Crown Prince has?" ”

In fact, Li Chengqian had already been scolded in his heart.

Li Chengqian smiled and said something that made Li Shimin nod yes.
