"Let's use your imagination to guess the reason." Li Mu nodded with a smile, indicating that he would enter the next link.

Everyone could not guess, so Li Mu had to solve the answer by himself and said: "The secret of the blue flame is on the lotus eyes that are like small chimneys; the fire is gentle, the shape has not changed, and the coal ash is small because of the yellow mud; as for why there is no smell, it is because of the slurry of lime. All the secrets are here, and I have not hidden it at all."

Li Shimin and Eunuch Gao stared at each other and listened to Li Mu's words, their faces were filled with question marks, exclamation marks and ellipsis.

"What is this and what?" Eunuch Gao said he didn't understand a word.

"You must be good at observing in normal times!" Li Mu said slowly: "When burning the stove, as long as you pull the bellows, the fire in the stove will burn vigorously, and it will be the same blue color. In the charcoal, charcoal that also burns blue flames is the most thorough burning type of charcoal. The small chimney-like lotus eyes play a role in ventilation. The reason for the mild fire is that yellow mud is added to the coal powder, reducing the content of coal. The yellow mud will become stronger and stronger when heated, rather than dispersing, so the shape will not change, and there will be so much coal ash. Lime can react with the smoke-free smell. When the two are neutralized, there will be no odor. This is a method to find out continuously."

Li Shimin looked at Li Mu with a confused look and said, "Looking for a needle in a haystack, how did you do it?"

Li Mu smiled and said honestly: "There is nothing else, I'm just annoying. I'm just talking, and Your Majesty doesn't know." As he said that, he looked up at the moon and said: "When I was in the sky before, I was--"

"Okay!" Li Shimin said angrily: "You are fat and you are still breathing. Do you really think that you are from heaven? Let's go and go back to the house."

As he said that, Li Shimin pointed to the coal lotus root and said, "Get a few pieces here to keep me warm. I will bring a car when I go back tomorrow!"

A car? I really dare to speak!
