Seeing Lu Xuan run away without hesitation, the prince felt a wave of depression welling up in his heart.

"Chang Yuan, what do you mean by Lu Xuan? This prince... Chang Yuan, you..." As soon as he spoke, the prince realized that Li Mi's attention was not on him, but on his body.

on the chair below.

"This kind of bench..." Li Mi stroked the chair under him, thinking for a long time but couldn't think of a suitable adjective.

At first glance, it feels too high. But when you sit down, your legs can be stretched out naturally. Although it feels a bit inelegant, it has a unique sense of comfort. The most important thing is that the backrest behind the back, combined with the soft cushion under the buttocks, can

It allows people to sit down effortlessly, giving them an unprecedented sense of relaxation.

He picked up the 'tea' in front of him again.

The tea of ​​the Tang Dynasty was completely different from modern tea. They used various onions, ginger, dates, orange peels, and even nutmeg, sesame and other spices, added tea leaves and boiled them in water to create a tea that modern people think of as

Dark drinks. Lu Xuan couldn't drink that kind of tea soup. He actually didn't know how to fry tea, he just made a lot of tea leaves based on his imagination. But he really made some tea leaves with the taste of later generations.

He didn't ask for much, just a little tea flavor would be nice. However, this kind of tea is still a rare thing in this era.

Li Mi picked up the tea and took a sip gently. A slight bitterness was introduced into his mouth. But then, there was a fragrance mixed with it. After swallowing it, a sweet aftertaste appeared.

"It is bitter at first and then sweet, with a pleasant fragrance. But it is a good drink." At this time, the prince also realized that something was wrong. In this small Wannian county magistrate's house, everything they saw so far,

They are all novel things that have never been seen before.

Chang Yuan stood up again and walked to the strange-looking iron tool. As soon as he got closer, he felt an obvious heat. Only then did he realize that it turned out to be a stove.

It's just different from the common brazier style. The thing is made entirely of iron. It's about the height of a human leg, and there's an equally weird-looking iron kettle placed on it.

Through the gap, you can vaguely see a strong flame burning under the kettle. This design alone is far beyond the brazier. It not only provides heat, but also uses the heat to boil water, but it has the effect of killing two birds with one stone.

The prince was obviously attracted by this strange stove.

"This stove burns so vigorously, I wonder what kind of charcoal is used?"

"No, it's not charcoal." Li Mi stretched out his hand and tentatively grabbed the handle wrapped in some kind of leather above the kettle. It wasn't hot, so he reached out and lifted the kettle directly. What caught his eye were pieces of burning red color, like

Transparent stones. Red and yellow flames burned blazingly on the stones.

"This is... charcoal?" Li Heng was not an uneducated person. The main reason was that charcoal had been used to make iron in the Tang Dynasty. This was an important military matter, and he naturally understood it.

"It's coal."

"I once heard that some people used charcoal for heating, but the result was that the whole family died of carbon poisoning. Is it possible that Lu Xuan wanted to kill us?" The prince became angry on the spot when he heard this.

"Your Highness, don't panic. Lu Xuan didn't know that we would come today. How could he light up the coal by such a coincidence? Besides, we have been here for a while, but we didn't feel the slightest discomfort. It can be seen that there must be something wrong with this.

We don’t know why.”

As Li Mi spoke, he looked at the towering chimney. He walked along the wall and walked out of the door. Sure enough, he saw the chimney turning at the roof, sticking out of the wall, and spitting out continuously.

Green smoke.

"If I guess correctly, this iron pipe should be the secret."

"cigarette?"

"Yes, we have long confirmed that carbon poison is hidden in smoke and dust. But in winter, it is natural to close the doors and windows tightly to keep warm. And if the doors and windows are closed tightly, the smoke and dust cannot spread. Open the door to disperse the smoke and dust, and you cannot keep out the cold. Therefore, we force

All users died of carbon poisoning. The government eventually banned charcoal heating. But now it seems that Lieutenant Lu has solved this problem, right?"

There was an uncontrollable emotion in Li Bi's words. Because he even said that solving the problem of carbon poisoning was a matter of great merit. Coal has been discovered in many places, but not many of it can be used.

The nobles used charcoal for heating. However, most common people could not afford charcoal and could only use firewood or resist. If charcoal could be used on a large scale, the number of people who died due to cold every winter in the Tang Dynasty would be greatly reduced.

With this achievement, Lu Xuan was promoted to the third level.

But the Lu County Lieutenant did not report the matter, but used it in his own home. No, not just in his own home. He was actually waiting for the prince to see it.

Just as the two of them were sighing, Lu Xuan and the old man came over carrying some dishes.

"Your Highness, it's cold outside, so let's go inside." Lu Xuan still didn't explain what he meant, but just invited the prince to come in. Li Bi glanced at the dishes in Lu Xuan's hand, and his expression became even weirder.

There is no other reason than that all the dishes are fresh green vegetables.

Very fresh, completely different from the yellow and shriveled vegetables stored in cellars in the palace. The green vegetables on the table are all real fresh vegetables. Pork, spinach, courgette, and mushrooms. Or

Stir-fried or served cold, it looks particularly tempting in the winter of the Tang Dynasty.

It may be difficult for future generations to understand how delicious a few plates of vegetables are. But there is no way, the limitations of the times are like this. In fact, it is not that there were no greenhouses in the Tang Dynasty. Earlier in the Western Han Dynasty, there was already the idea of ​​greenhouse cultivation. But those

Most greenhouses are realized with the help of natural hot springs and sealed environments, and are not universal.

In this era, if you want to artificially manufacture a greenhouse, you need to use a large amount of combustibles, that is, coal. This in turn involves the promotion of coal. Going around and around, we still come back to the issue of coal and carbon toxicity.

The prince and Li Mi seemed to agree with Lu Xuan's non-explanation style. They did not continue to ask, but just immersed themselves in eating. They knew that Lu Xuan would explain at the right time.
