Fan Yonglin's words can be said to be a bolt from the blue, and the crowd exploded all of a sudden. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Some things actually exceeded Fan Yonglin's expectations, the previous emperor preferred carpenter work, while the current emperor seems to be a little more reliable, but he prefers strange skills and tricks, and he even publishes a book.

However, in the minds of these ordinary people, they still feel that Chongzhen is reliable. Of course, this is the result of comparison. After all, Chongzhen at least has a physical object to show in front of everyone, which is more real.

In this Ming Dynasty, the emperor represented the supreme authority. Fan Yonglin asked like this, even the more courageous scholar just now did not dare to raise any more questions.

Therefore, although everyone did not agree with Fan Yonglin's words, they still sang the praises of Chongzhen in unison.

Such as: the current emperor is wise and martial, unparalleled in wisdom, talented, and has competed in Wenqu and so on.

If sycophancy really becomes a doctrine, I'm afraid that people all over the world will rush to it.

The scholar was also dumb at this time, in his education, the king is the sky, the emperor means the sky, how to say bad things about the emperor, so he just smiled awkwardly, in order to hide his inner panic and uneasiness.

At this moment, no one noticed that there was an old man in the crowd, his hair was gray at this time, but his scorching eyes revealed their essence from time to time.

Just when the audience was dumbfounded and Fan Yonglin was quite proud, the old man spoke: "According to what you said, the burning conditions are all from the book in your hand, I remember that you just said that there are three points for the burning conditions, but you only said two points, so what is the third point?" ”

At this time, people shouted in unison as if they were saving face, asking Fan Yonglin to say the third point of the burning conditions, and in that scene, if Fan Yonglin could not say the reasonable conditions, everyone seemed to swallow him alive.

Fan Yonglin had already experienced this chaotic scene, and he had already prepared in his heart. Therefore, he motioned for everyone to be quiet, and then said: "That is nature, and the third condition of this combustion is actually contained in the principle of making honeycomb coal, have you already thought of it?" ”

Fan Yonglin said this, suddenly stopped, he looked at everyone mysteriously, he swept his gaze over everyone's faces one by one, every time he saw a person frowning and thinking, there was a trace of pride in his heart.

In the end, Fan Yonglin's gaze stayed on the gray-haired old man just now, and said, "Old man, do you know the third condition for this burning?" ”

The old man thought for a moment and said confidently: "If the old man didn't guess wrong, it must be related to the contact area you just said. ”

Fan Yonglin really didn't expect that an ordinary old man here would have such insight, and he couldn't help but take a few more glances at this old man. At this moment, he realized that the old man's eyes were shining with fine light, and this old man was by no means simple.

But this hesitation, to say a long story, is actually in a blink of an eye.

After hesitating, Fan Yonglin continued the old man's words and said, "Yes, old man, you are very right. The third condition for this combustion is to be in full contact with the air. Because, there is a gas in the air called oxygen, which can help other substances to burn, and the emperor called it combustible gas.

In other words, for a substance to burn, oxygen must be present, and the greater the contact area with oxygen, the more fully it will burn. As for what the old man said just now, I don't understand the contact area, so I'll explain it to you now.

You see, I have a piece of coal on my left and right hands, everyone pay attention to it, what is the difference between these two pieces of coal? ”

Everyone saw Fan Yonglin holding two pieces of coal in his hands, one was the common briquette, and the other was the honeycomb coal that Fan Yonglin said.

For a while, everyone was full of doubts.
