"It's only 10,000 catties of strength, so shocked, senior sister, you can't help but underestimate this gear set. ”

Qin Yunfei smiled hesitantly, and once again asked Lin Feixue to increase the application of the gear set.

"Hmm. Lin Feixue nodded slightly, and the strength in her hand also increased a lot.

But seeing her gently increase her force, the numbers on the strength detector have undergone drastic changes.

"Two ...... Twenty thousand!" Nangong Zixun couldn't help but read it out of his mind when he saw the number on it.

However, it is clear that this number does not end there.

The strength data on this detector actually increased from 20,000 to 110,000 until it was 37,000, and then it stopped suddenly.

This time, Qin Jiu and Nangong Zixun both opened their mouths wide and looked at the testing instrument in front of them in disbelief.

"Three...... Thirty-seven thousand, this is the peak of the Soul Emperor, the power that can be released......"

Seeing such a result, Nangong Zixun had already begun to regret the bet with Qin Yunfei.

However, at this time, Lin Feixue was not in a hurry to exceed thirty-seven thousand, obviously she had other ideas, so she didn't ask carefully.

"Senior Brother Qin, Senior Sister Feixue, how did you do it? This gear doesn't seem to have any effect at all, how can it make such a big change in strength?"

Nangong Zixun looked at Qin Yunfei cautiously, she hoped that Qin Yunfei could give her a simple explanation.

At this time, Qin Yunfei didn't make a score, just smiled slightly, stood up, and began his explanation.

At this time, he looked at the seesaw where the children downstairs were playing, and suddenly laughed.

"I don't know Senior Sister Nangong, have you ever played seesaw?"

Qin Yunfei's greeting, Nangong Zixun couldn't help frowning.

"Senior Brother Qin, what I'm asking about is the magic of this gear, what do you tell me about the seesaw?"

Seeing her performance, Qin Yunfei shook his head helplessly, and then waved his hand, "Feixue, don't give face." ”

Lin Feixue nodded, and immediately exerted force, but when she saw the strength result on the detector, it exceeded 37,000 catties, reaching 37,000 catties.

Nangong Zixun couldn't hold her face when she landed, she blushed, and she didn't dare to say anything, so she could only look at Qin Yunfei and Lin Feixue in embarrassment, waiting for his explanation.

And Qin Yunfei also began to explain to him at this time.

"Senior sister knows the principle of this seesaw. In fact, it is a matter of the product of moment and force. ”

With that, Qin Yunfei returned to the dinner table, he took the wine glasses of the four people in his hands, and found a ruler to make a simple seesaw.

"Everyone is optimistic, in the seesaw, which can also be called the lever structure, as long as the product of the force and moment of the two sections of the lever is equal, then they can achieve a balance. ”

So, Qin Yunfei began to do a simple product conversion.

"You see, this is equidistant and weighty, and the ruler is balanced. ”

Qin Yunfei showed a simplest seesaw structure, and this structure can be understood by everyone.

However, after he showed this structure, he changed to a second one.

"You see, this is a state of double the moment and twice the quantity. ”

At this time, the two cups on the left are three inches long, and the one cup on the right is six inches long, and the ruler has also reached a balance point.

"Do you see? When the product of the two sides is equal, what we get is a balanced structural state. ”

Nangong Zixun and Qin Jiu were thoughtful, but the former still had doubts.

"Although there is such a thing, but what does this have to do with your gear? This gear, after all, is not the same as a seesaw. ”

Qin Jiu also nodded at this time, "Yes, what Senior Sister Nangong said is right, how can this seesaw be compared to gears?"

Seeing that they were all so confused, Qin Yunfei couldn't help but laugh and took out a gear from his pocket.

"I say two, you see this is a gear, but if you look at it this way, what do you think it is?"

At this time, Qin Yunfei covered the upper half of the gear and the lower half of the gear with his hand, and only one middle horizontal was left of the gear.

But even so, these two people still can't see what they have in common.

"I don't see any similarity. It's obviously a cog. Nangong Zixun scratched his head, his heart was in turmoil.

Seeing the posture of the two of them, Qin Yunfei smiled helplessly, "Don't think about the original appearance of the gear just now, just look at the position of the gear I showed, this left and right, is it like the two sides of a seesaw?"

Qin Yunfei reminded him like this, and the two of them seemed to understand something.

"yes!

Qin Jiu patted his forehead and seemed to understand. But he still couldn't say anything.

And at this time, Qin Yunfei was not in a hurry, and the same gear came again.

He joined the external teeth of the front gear with the internal teeth of the other gear.

Now, if I look at the first gear, if I gently wave the outer teeth of the first gear, then it will be in contact with the gear. And according to the current state, I only need to fluctuate lightly, and I can exert dozens of times the power. This is the application of gear, the persistence of leverage. ”

Qin Yunfei's final explanation was like a ray of light, making Qin Jiu and Nangong Zixun like thunder.

Nangong Zixun suddenly squeezed the teacup tightly, "Senior Brother Qin, you are really a god! As soon as you explain this, I will fully understand! If this is the case, then wouldn't I be able to exert the power of the Soul Venerable level?"

She looked at Qin Yunfei excitedly, obviously wanting to get Qin Yunfei's affirmation.

And when Qin Yunfei saw her serious expression, he shrugged his shoulders very boredly.

"The power of the Soul Venerable is easy to achieve, but the key is that you can find materials that can pour out the power of the Soul Venerable for gear construction. ”

Qin Yunfei said, Nangong Zixun was in trouble.

"You're right, hey, it seems that it is obviously impossible to use the level of the Soul Emperor to exert the ability of the Soul Venerable. ”

She sighed, thinking that she had found a way to become stronger, but who knew that in the end, it was still empty, how could she not lose it in her heart?

But when she lamented, Qin Yunfei smiled hesitantly, "You don't have this kind of material, but I have this kind of material." ”

Qin Yunfei said this, and Nangong Zixun's originally wilted spiritual head was instantly restored.

She grabbed Qin Yunfei's big hand excitedly and asked excitedly, "Senior Brother Qin, you can say it quickly! How can you do it! Do you really have this kind of material?"

She was so excited that she forgot the difference in the identities of the two, but seeing that Qin Yunfei didn't reply for a long time, she noticed Lin Feixue's strange gaze, and then quickly threw away Qin Yunfei's big hand.

"Sorry...... I lost my temper just now......"
