Jiang Yunxiao subconsciously thought that Leng Shaochen would bring a lighter, so he forgot about making a fire. But in fact, Leng Shaochen doesn't smoke, so there is no such thing as carrying a lighter with him.

Because Leng Shaochen is, first, he doesn't smoke, and second, in the process of business cooperation or at parties, he doesn't need to light fires for others.

"Why don't you try your hand at drilling wood for fire now?" , Jiang Yunxiao proposed.

"How long does it usually take to drill wood for fire? And I haven't tried it yet, and I don't know how much time it will take. Leng Shaochen thought for a while. And it's almost five o'clock now, so I don't know what time it will be before I can eat the barbecue if I really dig into the wood......

"Forget it, I'll go back and get the lighter......," Leng Shaochen said to the firewood in his hand.

"Inside the house...... Are you sure there is a lighter? Jiang Yunxiao shouted as he looked at Leng Shaochen's back. Since the house was made of wood, and there was no place to use a lighter, she wasn't sure if there was one.

"It's okay, if there's no lighter, then I'll borrow a fire from the stove~"

Jiang Yunxiao: "Borrow a fire from the stove?"

Jiang Yunxiao didn't understand what Leng Shaochen was talking about just now, but she didn't ask much.

After about a few minutes, Jiang Yunxiao saw Leng Shaochen walking over with an incense candle and blocking the wind in his hand.

Jiang Yunxiao smiled angrily, "You actually took incense candles and lit a fire??? ”

"How else would you come here?" , Leng Shaochen asked, "There is no lighter, so I can only do this." ”

Leng Shaochen walked over quickly with the incense candle, for fear that the fire burning in the incense wick would be extinguished by the wind. "Wait a minute, your barbecue will have the smell of this aroma~"

"Then I think it might be~", Jiang Yunxiao nodded, "I'll not skewer so many fish first, and then come to skewer when it's almost roasted." ”

"Well, you can skewer a little more pork belly to grill, and it's easier to cook," Leng Shaochen nodded and said. "You can also let the pork belly develop for a while, and after a while, it will taste a lot. Have you taken cumin powder, sprinkling some cumin powder will smell a lot~"

"Of course. You don't smell the smell of the aroma coming out of the pork belly......," Jiang Yunxiao said, "I didn't just sprinkle the pork belly, I sprinkled cumin powder on basically all the meat here." ”

Because Jiang Yunxiao made a lot of leaves when he was collecting firewood, he used it to make a fire for later use, so when Leng Shaochen started the fire, the fire was quickly lit.

"You picked up a lot of dead leaves, and it's better to make a fire~", Leng Shaochen smiled, "I didn't even get it much~"

"Isn't that good? I'm going to pick up leaves to start a fire~", Jiang Yunxiao said, "And now that the fire is burning just right, then you can grill the fish early." Anyway, I don't plan to grill the fish over charcoal, otherwise I don't know how long it will take to burn the fire, or when it will be ready. ”

Leng Shaochen used several large stones to circle the fire, and then hung the two ends of the skewers on the stones, and roasted the fish directly above the flame.

"Your skewer is just right, no wonder you use such a long skewer ......," Jiang Yunxiao said.

"When you skewer the pork belly, put the pork belly in the middle, so that it will be easier to bake and more evenly when the time comes~", Leng Shaochen reminded.

"Oh, good. If you don't say it, I won't pay attention to this yet. Jiang Yunxiao nodded and adjusted the position of his skewers.

Because in general, when you grill meat, you will habitually wear the meat at the front end and then grill it yourself with the tail end. But now, if you use a fire to roast, it will definitely be very hot, so you can't hold it with your hands all the time, and without a barbecue net, your hands will be tired all the time.

Like Leng Shaochen's idea, it is also very good to hold the stones at both ends, so that you don't have to take it yourself to roast, and the heating is relatively even.

"It's a longer skewer, you can use it to grill some thicker meat. Because the fire in the middle is the strongest, and the skewer that needs to be used is the longest. Leng Shaochen explained, "But if you grill some shiitake mushrooms or pork belly, you can choose shorter skewers, and then the number of skewers is smaller, and put them on both sides of this circle, so that you can control it better." ”

Because if the flames on both sides are not so big, it may rely more on the transmission of heat gas, and the pork belly is easier to cook, so it is not easy to burn. The string is less because of the two sides of the circle, the closer you get to the edge, the smaller the space will be, which is also the principle that the diameter of the circle is the longest. If there is less meat on the skewers, the food will not come into contact with the stones, so as not to stain the food.

"Huh. I didn't expect some physical and mathematical principles to come out of a barbecue......", Jiang Yunxiao said with a smile, "I think the junior high school teacher would be very relieved if he knew......

Because these principles are the basic knowledge of some junior high schools and primary schools, as long as you are not too stupid, you can quickly understand the truth.

"Then if you say something like this, shouldn't my college and high school teachers cry?" Leng Shaochen asked, "because I didn't use the knowledge they gave me??? Or is it better for me to think about whether I can use the knowledge they give me in the future? ”

"You said it yourself, I didn't say ......," Jiang Yunxiao said with a shrug. You can measure some objects, know the length and angle of the two sides, and find the length of the third side. ”

"Huh...... I'm really going to be laughed at by you......", Leng Shaochen looked at Jiang Yunxiao helplessly, "Why do you have to make so much trouble when you can measure directly with a ruler?" Didn't your teacher teach you to keep simple things as simple as possible? Isn't it self-inflicted suffering to do so many things? ”

"So I still don't quite understand what the teacher told us to learn so many trigonometric functions, what are the maximum and minimum values, what are we doing?" , Jiang Yunxiao said with a smile, then took the pork belly he had dressed and handed it to Leng Shaochen and continued, "Do I still use trigonometric functions when I buy vegetables?" ”

"Although it is difficult for ordinary people to use these things in their daily lives, some professional workers may use this method to solve problems." , Leng Shaochen said, "The teacher's teaching at that time was just to teach more people the truth in this. ”
