It was already past noon after visiting the cement factory. No matter how ignorant Li Mu was, he couldn't let Li Shimin eat with the Liba people in the factory. However, Huixian Yamen was a little too late. There happened to be a Sanqing Temple nearby, so he had to clean it up.
, it was still clean, so I chose this place to eat.
This really caught people off guard. Fortunately, Li Shimin was not a pampered person. When the palace was in dire straits, he didn’t eat well. Li Mu asked Dugujiu to get some game in the mountains, and then he had a barbecue directly. In the Western Region
With the blessing of fennel, I felt very happy eating it.
After dinner, Li Mu asked Li Shimin when he would go back, but Li Shimin glared at him and said, "Why are you rushing me away? I tell you, I won't go back today, so I will rest here, and you will stay with me."
.”
Li Mu secretly cursed in his heart, I am accompanying you like a ghost, leaving the little secretary who just joined the family without me, and I am accompanying you like an old man... But he only dared to think about it, and would never dare to say it. Li Mu smiled and agreed.
, ordered the guest room to be cleaned, burned incense, laid out new seats, and made some tea snacks, candied fruits and the like. At this time of year, in this kind of place, these things are really difficult to get, but Li Mu can get it, Li Shimin is a little bit better.
It's not surprising, he is used to being extravagant and wasteful when it comes to food and clothing, so it would be strange if he didn't have any.
In fact, Li Mu didn't ask about these trivial matters at all.
But who can make his family so blessed? He doesn’t have to worry about it at all. The little secretary at home has already arranged it. In the past, when the little secretary was not around, several women in the family were also rushing to think about him. He just wanted to
Just say something when you want something, and someone will bring it to your lips.
This shows how important it is for a successful man to have a good woman. Li Mu is more than just a virtuous wife, he is truly a blessing from his previous life.
…
In the back hall, Li Shimin took a bath, washed himself, and put on ordinary people's clothes, making him look more approachable.
Li Mu had already made tea and was waiting. When he saw Li Shimin coming, he was as attentive as a eunuch: "Thank you for your hard work, Your Majesty. Please use the tea."
Li Shimin picked up the tea cup and took a sip. The fine Longjing tea brought back sweetness and made people linger.
"In the past, I didn't like drinking tea, and I liked drinking alcohol. But since the advent of roasted tea like yours, I don't like drinking alcohol now, but I like drinking tea." Li Shimin clicked his lips and said: "Tea is bitter at first and then sweet. Taste it.
Just like life."
Li Mu was too lazy to talk about the principles of life with Li Shimin. He was now eager to put Li Shimin to sleep so that he could go back and chat with his little secretary. When he heard his words, he just smiled perfunctorily and said nothing.
But Li Shimin seemed to have seen what he was thinking, pointing at him and laughing and scolding: "I don't know who gave you the courage to marry Wei Zheng's daughter. With such an old father-in-law, you are not afraid of his involvement in the future."
you?"
"Can you take ginseng?" Li Mu said like a dead pig not afraid of boiling water, "If ginseng kills me, his daughter will be a widow. If he can do it, then I will be convinced."
"So that's the idea." Li Shimin smiled, knowing that Li Mu was talking nonsense. He and Wei Zheng are both strong-willed people, and they would definitely not change their original intentions just because of an additional relationship.
"Since you came back, I forgot to ask you something. How is Li You, a common man from Qi, doing now? His mother misses him very much."
"Shu Renyou," Li Mu felt fresh after hearing this word, but he couldn't bear to dismiss Li Shimin, so he said, "He is living a good life now. He is a librarian in the literature library. He deals with books every day and spends his free time
He studies even if he has nothing to do. After all, if he is literate, he won't be able to do much for the time being, but if he is willing to learn, there will be no shortage of well-educated people in the literature library, and he may not be able to become a talented person in the future."
"That's good -" Li Shimin sighed and said, "Shu Zi is disobedient. If he had worked hard like this, how could he have become like this?"
"What are your plans next?" Li Shimin changed the subject and asked, "I heard that you invented a new thing called briquettes?"
Li Mu thought to himself, you are really well-informed. A few days after this thing was made, you got the news again, which shows how many informants have been planted around me.
He knew it well but could not show it, saying: "Your Majesty will not tell you, but I will show it to Your Majesty."
As he spoke, Li Mu stood up and said to Li Shimin: "Your Majesty, please wait a moment while I go make arrangements."
Li Shimin signaled Li Mu to help himself, and Li Mu turned around and went out. After a while, he came back and said to Li Shimin: "Your Majesty, please move to the woodshed, and I will show your Majesty the briquettes."
"I was just about to take a look." Li Shimin stood up. Eunuch Gao brought some furs and put them on Li Shimin, and followed Li Mu to the woodshed.
Beside the firewood pile in the woodshed, there was a small pile of pulverized coal, as well as a pot of loess, a pot of slaked lime, and a pot of sawdust. Li Mu commanded a Jinyi guard to dig out four pots of pulverized coal with a shovel, add water, hydrated lime, and
Stir the loess evenly.
After completing these preparations, he went into battle in person.
He took a mold for briquettes, dipped the mold tube in water, and then put it into the mixed coal slurry.
After compacting it with both hands, Li Mu lifted the mold and moved it to a clean place to rest it.
Then he supported the pole with his abdomen, lifted the cylinder with both hands, and the briquettes, which were as big as the mouth of a bowl and looked like super-large lotus root segments, were ready.
"good!"
Eunuch Gao was indeed an old fan, so he took the lead in shouting.
Li Shimin glanced at him with a frown and said, "What's so good about it?"
"It looks good..." Eunuch Gao muttered in a low voice. In fact, he didn't understand it yet and was used to praising it.
"What's so good about it?" Li Mu wiped his hands and asked with a smile.
"Look at his round hole, it looks like a white lotus root overwhelming the mud."
"Your lotus roots are black." Li Shimin rolled his eyes at him, but Li Mu still wanted to give Eunuch Gao some face, saying: "It does look a bit like it, so let's call it 'coal lotus root' in your words."
Eunuch Gao chuckled and said, "Thank you, Lord Marquis, for rescuing the siege."
Li Shimin approached the coal lotus root and asked, "I think the coal lotus root you made is for burning?"
"Well, it's not food." Li Mu smiled bitterly without saying anything. Isn't this nonsense?
Li Shimin also discovered his language problem and said: "What I mean is that burning it this way is definitely better than burning it loosely, but I can't guess what the benefit is."
"Then please continue to read carefully, Your Majesty, and I will answer your questions."
Li Mu then continued to instruct the Jinyi guards to mix sawdust into the remaining coal slurry, then carry the prepared coal cakes to the kitchen and bake them on the stove.
In this way, the coal lotus roots can be dried quickly, otherwise Li Shimin would not have the patience to wait for several hours.
About half an hour later, Li Mu checked the coal lotus roots and saw that the briquettes had dried.
"Your Majesty, you can continue."
Li Shimin nodded and motioned to Li Mu to continue the demonstration.
"In the spirit of scientific experiments, I asked them to prepare three rooms and three charcoal pots."
Li Mu asked people to bring over the charcoal basins and explained to Li Shimin: "These three basins contain ordinary loose coal, coal lotus root made of ordinary loose coal, and high-quality Taiyuan coal."
"Hmm." At this moment, not only Li Shimin, but also everyone who could hear Li Mu's voice wanted to see what he was doing.
People are naturally curious, so how can anyone not be interested in new and unprecedented scientific experiments?
"Come on, let's light them separately." Li Mu snapped his fingers.
Two Jin Yiwei stood up and went to light the two pots of loose coal respectively. It took them a long time to get to the matter of the open flame.
Li Mu only used the tinder from the lamp to light a piece of lotus root.
"So easy?" Li Shimin was surprised. In his impression, coal is difficult to light. If you want coal to burn, you must first use charcoal to start the fire.
Although he was an emperor who was unconventional in his affairs, he still had some common sense.
"Because this piece of coal lotus root is mixed with sawdust." Li Mu said with a faint smile: "The other two ordinary pieces of coal lotus root are not so good. But if this one catches fire, they will also catch fire."
"Wonderful." Li Shimin couldn't help but praise.
"Put the charcoal basins in the three rooms respectively." The doors and windows were sealed, and Li Mu stood at the door of the three rooms, not knowing what he was waiting for.
After a while, everyone was choked by the billowing smoke. But the coal smoke was too terrible. As long as the coal stove was lit, the room would be filled with thick smoke, making it impossible to stay.
We then took people into the room where Taiyuan coal was burned. It was indeed much better here, at least there was no smoke or dust.
"This Taiyuan coal is really good. I heard that many people use it to replace firewood." Li Shimin said down-to-earth, "But it's still a bit choking, so rich people still burn charcoal."
"Yeah." Li Mu nodded in agreement. Although there is no smoke visible when this so-called "Taiyuan coal" burns, it will still choke people if it is left nearby for a long time.
Finally, they entered a room where briquettes were burning.
Everyone was surprised to find that the coal lotus root made of ordinary coal had no smoke and was not choking after burning for so long...
"Why is there no smoke?"
"Why is there no smoke?!"
“And it doesn’t choke!”
Looking at everyone's stunned look, Li Muxin said that this formula of briquettes was still being used on a large scale in rural areas four hundred years later. Wouldn't it be more relaxing and enjoyable to shock you?
"There's no soot yet..." Eunuch Gao wiped the wall and saw that his fingers were as smooth as ever, and he couldn't help but exclaimed.
"You are observing very carefully." Li Mu nodded approvingly, but Eunuch Gao didn't even dare to say so.
But everyone looked at Li Mu and asked him what was going on?
"Say it directly, I'm afraid everyone won't remember it." Li Mu put his hands behind his back and said with a smile: "Why don't you try to use scientific methods and study it yourself?"
"What is the scientific method?" Li Shimin humbly asked for advice. The longer he interacted with Li Mu, he felt that he knew very little...
"It is a method of conducting research under the guidance of scientific spirit." Li Mu pointed to the pot of fire and said: "Please observe carefully."
"Use your imagination to find the answer." Li Mu said calmly.
"It is about respecting evidence. Imagination must be based on objective evidence, rather than random speculation."
"It is dialectical thinking, which requires thinking and evaluating the facts seen as a whole and essentially."
"Don't be stubborn. You must actively accept empirical conclusions and actively adjust your own perceptions..."
“It’s about treating failure with tolerance and believing that truth comes from constant trial and error!”
After a cup of tea.
Li Mu then asked with a smile: "What did your Majesty observe?"
"The color of this fire is different!" Li Shimin said in an uncertain tone: "It is blue! And the fire made from loose coal is red!"
"This is the color when charcoal burns!" Eunuch Gao quickly added, then looked at Li Mu expectantly.
"Yes, I observed very carefully." Li Mu nodded with a smile to show encouragement.
"The flames produced by this coal lotus root are small and soft, not as fierce as those two charcoal pots." Li Shimin added.
"What else?" Li Mu asked again.
"After burning for so long, the shape has not changed." Gao Eunuch took a pair of fire pliers and poked it, and found a piece of red honeycomb briquettes and said: "It's quite strong, no wonder there is no soot."
"Let's use your imagination and guess the reason." Li Mu smiled and nodded, signaling to move on to the next step.
No one could guess, so Li Mu had to solve the mystery himself, saying: "The secret of the blue flame is probably in the lotus holes like small chimneys; the fire is mild, the shape has not changed, and the soot is small, these three points should be all because of it.
It's because it's mixed with yellow mud; as for why it has no taste, it's because of the slaked lime."
Li Shimin and Eunuch Gao listened to Li Mu's words with their eyes wide open, their faces filled with question marks, exclamation marks and ellipses.
"What is all this?" Eunuch Gao said he didn't understand a word.
"When burning the stove, just pull the bellows, and the fire in the stove will burn brightly and turn the same blue color..." "After burning for so long, the shape has not changed." Eunuch Gao took a plier and poked it.
He poked a piece of red briquette and said: "It's quite strong. No wonder there is no soot."
"Let's use your imagination and guess the reason." Li Mu smiled and nodded, signaling to move on to the next step.

Li Shimin and Eunuch Gao listened to Li Mu's words with their eyes wide open, their faces filled with question marks, exclamation marks and ellipses.

"When burning the stove, just pull the bellows, and the fire in the stove will burn brightly and turn the same blue color..." "When burning the stove, just pull the bellows, and the fire in the stove will burn brightly.
When the stove is burning, it will be the same blue..." "When the stove is burning, just pull the bellows, and the fire in the stove will be burning brightly, and it will be the same blue..." "When the stove is burning
, as long as the bellows is pulled violently, the fire in the stove will burn brightly and turn the same blue color..."
