Chapter 742: King Qi, the magic stick
"Hahaha, brother Bi, don't mind. This is all the idea of that old boy, the left prime minister, and we are also following orders." Huang Lao said, stroking his beard with a smile.
I don’t mind your sister! After learning the truth, Bi Yuntao hated the left prime minister in his heart. It turns out that his cheap father-in-law was behind all of this.
Huang Lao looked at Bi Yuntao's expression of constipation and felt so happy. He felt more and more that he was so smart that he not only took it out, but also took the opportunity to trick the old boy Zuo Xiang. When King Qi and Zuo Xiang meet again, they must watch this good show carefully. OK.
After Meng Ruolang's explanation, the context of some things became clear, especially He Yuqing. I couldn't blame her for suddenly appearing when she had something to do recently. It turned out that she was all following orders.
"Oh, what are you talking about now?" He Yuqing said: "Bi Yuntao, please tell us about the method of washing hands in oil pans."
"That's right, that's right." Huang Lao echoed from the side, "I'm also very curious about what is going on."
"Haha, let me tell you about it then." Bi Yuntao said with a smile: "This method is worthless, but you have to keep it a secret for me! Maybe I will use this again in the future. Woolen cloth."
Mr. Huang said with a smile: "The oil pot washing hands must be the same as the stone statue. There is a trick in the middle. It's just such a clever way that I can't figure it out."
"Not bad!" Bi Yuntao nodded: "Actually, this is a simple application of common sense. The trick is the vinegar in the oil pan."
"Jealous?" Xue Ruyue said in shock, "No wonder I smelled a bit sour. I thought it was coming from the restaurant below, but it turned out to be a bad guy like you who was causing trouble."
Mr. Huang said anxiously: "What's the point of being jealous? Brother Bi, please continue talking."
Bi Yuntao smiled and said: "When Meng Ruolang went down to look for oil, he followed the instructions I gave him and mixed the mature vinegar and oil into the pot. Since the specific gravity of vinegar is greater than the specific gravity of oil, the vinegar sank to the bottom of the pot. The oil floats on top. In this way, what everyone sees and what Meng Ruolang scoops up is oil, but no vinegar."
Huang Lao smiled and said: "I didn't expect there was a trick to it. So what's next?"
"The vinegar vaporizes quickly after being heated, and passes through the oil layer in the form of gas and rises up, causing the surface of the oil to boil like a rolling ball, accompanied by bursts of green smoke. It is very bluffing, but in fact , because there is vinegar between the oil and the fire, the temperature of the oil rises, and only the vinegar can be used to transfer heat, so it will not boil so quickly. What we see is just the effect of bubbles, and the oil has not yet boiled at all. Hot. Therefore, when Sister Xue reached into the oil pan to get the copper plate, everyone believed what they saw with their own eyes, thinking that Sister Xue would be injured, but it was actually a cover-up. In fact, the oil on the vinegar layer was only warm. of."
"I see." Huang Laodao said, "But what is the use of the scale you asked Meng Ruolang to secretly throw into the pot?"
This old man Huang was very careful in observing, and he even caught the techniques used by a strong martial artist like Meng Ruolang. Of course, Bi Yuntao couldn't explain to them that calcium carbonate reacts with acid to produce carbon dioxide. He could only briefly say: "The scale sinks to the bottom, and when it encounters vinegar, it will react and bubbles will appear. This way everyone sees that the oil pan is scalding hot." , but also more realistic.”
Xue Ruyue asked in confusion: "Then why did it happen to me when I went to get money, but Mr. Tao was seriously injured?" This was exactly what Huang Lao was puzzled about.
"Of course I did this on purpose. He dared to set his sights on Sister Xue. He was so brave!" Bi Yuntao laughed, with a sinister and evil smile on his face. Xue Ruyue's expression changed. Hong gave him a shy look, lowered her head and listened to Bi Yuntao continue to speak.
"You need to put an appropriate amount of vinegar into the oil pan, not too little, to ensure that the vinegar vaporizes and evaporates after being slightly heated. When the oil layer in the oil pan rolls and smoke comes out, there is actually very little vinegar left at the bottom of the pan, and the pot The oil inside is not too hot yet. When you put your hand in, you feel the temperature is right, so Sister Xue can easily take out those copper coins. Of course, you can't have too much vinegar. Too much vinegar will not easily vaporize, and the temperature of the vaporized vinegar will also be very high. , and it’s also very easy to get burned, so there’s a problem with the degree of control.”
"In this case, you must have deceived many people with this method before, otherwise how could you be so sure?" Xue Ruyue pouted. I feel a little bit tasteful.
Bi Yuntao smiled and said: "I'm not lying. There is another method here, and it is actually the simplest method. The amount of scale is small, and after a burst of bubbles, it is used up. The remaining bubbles are the vaporization of vinegar. . So, I have to keep an eye on the oil pan to see if there are still bubbles coming out from underneath. If there are no bubbles coming out, it means that the vinegar has completely vaporized. At this time, the oil temperature will rise quickly. At that time, the oil will It’s just really boiling.”
Xue Ruyue clapped her hands and said, "I understand. When I took out the coin, it was when the bubbles were the thickest and the vinegar had just begun to evaporate. The temperature was low, so I could take it out quickly. And Mr. Tao later stretched out his hand. When the bubbles were gone, the vinegar had completely evaporated, but the oil pan was really hot, and he was injured."
Bi Yuntao raised his thumb and praised: "Sister Xue is so smart."
"Disgusting." Xue Ruyue blushed and said coquettishly.
Bi Yuntao chuckled a few times and added: "Anyone who sees that hot oil pan will shy away, let alone touch it. But in the face of one's own safety and interests, leaving green mountains without worrying about having no firewood, Tao Pengju naturally understands this truth. I caught this mentality of his and knew that he would shrink, so I deliberately provoked him with words. As expected, he changed his mind and chose to shrink after hearing this. Plus, you The two of us argued back and forth, delaying time. By the time we took out the three copper coins, there was not much vinegar left. By the time Tao Pengju woke up from the shock, it was already too late."
"Brother Bi, you deliberately asked Tao Pengju to catch him first, but unexpectedly you resorted to playing hard to get." Huang Laowei sighed: "Brother Bi is young, but he has a very deep grasp of human nature. I since Ashamed."
"Where, where." Bi Yuntao smiled shamelessly: "How can I be as sinister as Mr. Huang?"
Mr. Huang's eyebrows jumped sharply. Could it be that he had tricked the left prime minister and Bi Yuntao had guessed it?
Xue Ruyue smiled softly: "If you go to the White Lotus Cult, you will definitely become a barefoot immortal. If you don't learn anything well, you will learn from the magic stick."
When she talked about the magic stick, she looked down at Bi Yuntao, her face turned red with shame, and her expression became extremely moving.
