"You...... You're going to pestering me...... Although you can get in, you can't get out without me......" Lu Miaozi said angrily, like a dog that has been damaged by heat.

"Wanwan, how can you be so rude to your seniors and still not let go of your seniors? ”

Yang Dong scolded Wan Wan harshly, walked up and said to Lu Miaozi with a smile: "Senior, you see that you are immortal and spirited, and you are ...... at a glance."

"At first glance, it's a bad old man. Lu Miaozi took over the conversation and said lazily: "Boy, you don't have to pat me on the back, let's make it clear, since the day Yang Gong's treasure house was sealed, I have sworn that I will never reveal the secrets inside to any outsiders."

Even if you kill me, I won't say it, even if you put me on the knife mountain and down the oil pot, I won't say, you just die, I will definitely bring this secret into the coffin. ”

Lu Miaozi's tone of voice was very light, but the more this was the case, the more Yang Dong and Wan Wan could hear Lu Miaozi's determination, the two glanced at each other, and saw despair in each other's eyes, wanting to ask Lu Miaozi about the whereabouts of the evil emperor relics, it seemed that it was no fun.

"I can't wait to ......" Wan Wan shook her palm, and stopped talking, Yang Dong said: "You want to use illusions, it's too lacking in virtue, right?"

"Hmph, it seems that we can only wait for the master to come. "Wan Wan is the same as her master Zhu Yuyan, although she is an evil figure, she is evil and has a way, and she disdains to use the Heavenly Demon Voice to deal with people like Lu Miaozi.

"Senior, what do you seem to be embarrassed about?"

Lu Miaozi was frowning and pondering at the handmade machine in front of him, Yang Dong glanced at it, the overall shape of this machine was like a horse, but it had flat wings, and I believe that it would be beautiful and majestic after it was completed.

"Boy, you want to help me please me, even if you have the heart, you don't have the strength. Lu Miaozi sighed. patted the dust on his sleeve, stood up and complained: "If it weren't for you, I would have calculated the capacity of this leaky bellows today, and if you don't hurry up, if you delay the date, I want you to look good." ”

Lu Miaozi finished speaking. Yawned, turned back to the room, and Yang Dong leaned over to Pegasus to take a closer look.

The structure of this Pegasus butt is very complicated, the overall structure is like a complex bellows, which is connected with the wings on both sides, I don't know whether to use the wings to transport wind to the buttocks, or use the bellows to pour wind into the wings, Yang Dong can't understand.

The bellows are constructed with wooden strips and some special materials, isolated into different shapes of leakage styles. Yang Dong estimated that it was to increase or decrease the air volume to control the speed of Pegasus's action, just now Lu Miaozi had been staring at the horse's buttocks, it seemed that this bellows was the bellows he said.

Yang Dong picked up the ruler next to him, measured it casually a few times, and said loudly: "The total capacity of the leakage box is seventeen liters of four, and the error is no more than half a centimeter." ”

Lu Miaozi had already entered the room and heard Yang Dong's words. Immediately, the figure emerged from behind the wall again.

"What nonsense are you talking about?" Lu Miaozi said with a straight face.

Yang Dong pointed to the horse's buttocks and said casually: "Tell me about your bellows volume." Don't you need this?"

"Fart, the old man has calculated for an afternoon today, and he hasn't completely calculated the volume of the bellows, you kid, you have nothing to do to entertain the old man, believe it or not, I'll kick you out now." Lu Miaozi walked out and said angrily.

"I don't believe you're doing the math yourself. Yang Dong said with his hands on his chest. Wan Wan walked over and whispered, "Really?"

"He's so stupid. Yang Dong said in a low voice.

Lu Miaozi's martial arts are very high, and when he heard Yang Dong's words, he was immediately furious: "Stinky boy, you wait for me, if I calculate it, it is not as much as you said." I'll kick you out at once, and leave you dead in the Valley of the Winds with no place to bury, huh. ”

Lu Miaozi sat down in front of the horse's butt murderously, picked up the ruler, he had calculated for an afternoon, almost half of the volume, all recorded in the small book, at this time while measuring with a ruler while recording in the small book, it took half an hour to finally calculate the volume of all the small grids.

It took another stick of incense to calculate, and the final number was obtained, and he silently read it out: "Seventeen liters of four-fold ......" Lu Miaozi was already dumbfounded, and Wan Wan also looked at Yang Dong in surprise.

The structure of the leaky bellows is very complicated, and it is not a regular body, how could Yang Dong get the result so quickly? Wan Wan thought that she couldn't do it.

"Little brother, tell me quickly, how did you calculate it?" Lu Miaozi stood up, grabbed Yang Dong, and asked with an eager face.

"Wow, it's really a water duck to a phoenix, so soon the stinky boy has become a little brother?"

"As long as you're willing to tell me the trick, I'll call you grandpa. "Lu Miaozi is already impatient.

Yang Dong was embarrassed, this Lu Miaozi was really a strange person, and he reluctantly walked to Pegasus and said: "In fact, the younger generation can get the result so quickly, or because the seniors have good craftsmanship, the cut and arc surfaces are very smooth, the round body is very rounded, and the italic intersection is also very concise, otherwise even if you can get the number, the error will be very large." ”

"What?" Lu Miaozi was confused. Wan Wan, Qin Menglan, and the Red Whisk Girl also came over to take a look, their eyes full of curiosity.

"Didn't the predecessors know that these triangles, arcs, fans and round bottoms can quickly get volume?"

"Of course I know this, I just use these rules to calculate the volume, but this leaky bellows are not all in the shape of these rules. ”

"It's stupid. ”

Yang Dong shook his head helplessly, looked left and right, saw a wire, straightened the wire, and stretched out his hand to stand in the leaky bellows, Lu Miaozi's eyes suddenly lit up, and he was speechless in shock.

"I didn't think of that. Lu Miaozi slapped her head suddenly.

"It's amazing, Brother Yang, you're so smart. Wan Wan looked at Yang Dong adoringly.

"Childe is really a genius in the world. The Red Whisk Girl said in admiration, as if Yang Dong was smart, and she was also stained.

"I didn't think to look at the bellows from this angle, as long as you add such a line, it is easy to see those irregular spaces, and they have become regular spaces, if you have the vision of the little brother, at most an hour, I can calculate the volume of the bellows, it's really incredible, it's incredible. ”

Lu Miaozi kept clapping and high-fived in admiration, as if opening a new door to the mechanical field.

Yang Dong looked at the old third girl in front of him with disdain, and said that there was no pressure on those who had learned modern high school three-dimensional geometry, and there were more things that looked strange in those application questions, as long as an "auxiliary line" was added, it immediately made people suddenly enlightened.

Yang Dong is the top student in the college entrance examination of the third middle school, his math scores are top-notch, and his memory has reached the realm of epiphany, so he regards this bellows as a three-dimensional geometry problem. (To be continued......)
