After Haosheng marveled for a while, Ye Wumian asked Wang Pandi: "So, Pan brother and sister, after seeing through the eyes and buttons of this mechanism, how are we going to open the stone door?"
Wang Pandi said: "This is easy. According to the common ideas in "The Brief Book of Mechanisms", you only need to close the eyes of the mechanism."
As she spoke, she pointed at the flies in the holes and said: "As long as we cover up the smell of blood, the flies will stop. Once the flies stop, the iron net will no longer be hit. The buckle will no longer be stimulated, and the mechanism will close naturally. The door opened."
There is nothing wrong with this idea, but Chu Yan has another level of worry.
"Of course, this is based on a premise: the iron mesh used as a mechanical buckle must be reusable. If the iron mesh buckle is ineffective after triggering the mechanism, we know this principle, but it is in vain and we cannot make it work. The agency is closed."
Seeing her worried look, Chu Yan consoled her: "Brother Pan, I said before that the mechanism in this stone chamber will not be disposable. I was not sure before, but now I have heard that the button in the stone chamber is not disposable. It is absolutely certain.”
Ye Wumian nodded.
Just think about it, flies are certainly attracted to the smell of blood, but they may also be attracted to other smells.
When the smell of blood permeates the stone room, it means there is danger in the stone room, which causes flies to hit the net and shut down the engine, so there is no problem.
But what if other smells, such as the aroma of food, trigger the activation of organs?
In this case, there is no danger, so you have to find a way to close the mechanism.
In this way, the mechanism that activates the mechanism must not be a one-time use. Otherwise, if it is activated by mistake, wouldn't it mean that you would be locked alive in the stone chamber?
Chu Yan smiled and said: "Actually, the probability of this mechanism being activated by mistake is quite high. If you don't believe it, take a look at this torch."
Ye Wumian looked towards the lighting torch pointed by Chu Yan.
There was actually some unsightly mud on the handle where the flames were not jumping.
After careful study, I discovered that the mud was nothing but the burnt remains of flies piled together to give it such a disgusting appearance.
"When the mechanism is activated by mistake, the best way is not to cover the source of the odor. If the source of the odor is covered, flies have memory, and they will most likely linger on that alluring smell and continue to hit the iron net. Therefore, the mechanism cannot pause."
Chu Yan pointed at the torch and said: "The best way is, of course, to raise the torch and burn the flies through the iron net. When the flies are dead, the impact force on the iron net is gone, and the mechanism does not need to wait for a moment. Stopped."
Ye Wumian also discovered at this time that the iron mesh of the ventilation holes was dark and there were indeed traces of burning. There were even some remains of flies stuck to the iron mesh of a certain hole, which seemed to be caused by incomplete burning.
"In this way, this mechanism is too troublesome, not to mention that it may start by mistake from time to time. After burning the flies to death, in order to maintain them in the future, they have to be replaced all the time." Ye Wumian complained.
Chu Yan said: "Master, it is actually necessary to change the flies. If the same group of flies always smells the smell of blood but cannot fly out, over time, they will learn to be smart and will give up hitting the net. By then, this The mechanism is useless."
Seeing that Chu Yan was not a student of machine arts, but could explain all aspects that he had not expected in such detail, Wang Pandi praised: "Sister Yan'er is smart and is a good candidate for learning machine arts!"
Chu Yan was very calm and unfazed by her praise.
With her delicate hands, she took off a torch next to the hole and poked it into the iron mesh at the entrance.
There was only a crackling sound, the oil smoke was gone, the smelly and fragrant smell was wafting, flames were everywhere, and half of the flies clinging to the iron mesh were dead instantly.
Ye Wumian casually pushed a gust of wind to fuel the flames and sent them in. All the flies that flew towards the iron net were burned.
There were many corpses scattered here and there, and they were all rotated away by the shaft in the hole and disappeared. There were also a few that stuck to the torches, mixed with the original mud, and became indistinguishable from each other.
After burning one hole, Ye Wumian and Wang Pandi went to burn other holes.
Instead of burning flies, Sleepless Night has not yet discovered that the arrangement of torches in the stone room is also in a regular pattern: wherever there is a hole, there is a torch.
He didn't think much about it at first, he just said that the torch was purely used for lighting.
Looking back now, it was probably so that after the mechanism was accidentally activated, it could be easily taken to burn the flies, so that the loss could be stopped in time.
No link is wasted, no link is wasted, but what is done is harmful to nature.
It's amazing.
When all the flies were burned and killed, before the three of them could speak, there was a "rumbling" vibration under their feet.
When Ye Wumian looked back, he saw that the originally tight stone door slowly opened and returned to the way it looked when he entered the stone chamber.
All three were delighted.
Wang Pandi looked at Chu Yan and said: "Sister Yan'er, I can't praise you enough! If you follow the method I mentioned to cover up the smell, I don't know how long it will take before the stone door opens. Your method, But it’s just an instant!”
Chu Yan said: "Thanks to you, you said that you want to open this door. When it is difficult, it is as difficult as climbing to the sky. When it is easy, it is like searching the bag to get something. Tonight we also did something like searching the bag to get something."
Smiling sleeplessly, he first picked up the three children and walked outside.
All three of them rescued the child and returned to the ground, standing outside the courtyard.
At this time, the sky has turned dark and green, the rooster is crowing in the distance, and the dawn of the 17th day of the twelfth lunar month is approaching.
After experiencing this night, I felt sleepless and in a trance, as if I was dreaming.
The understanding of mechanism art is not just a matter of surprise and admiration when I first entered this courtyard, which can be regarded as "disenchantment".
"This mechanism technique is exquisite and has many side effects. As for the one in the stone chamber, it is possible to activate the mechanism unknowingly through flies to destroy the intruders. But the accidental activation from time to time may be the problem. Be normal!”
Just in order to destroy the foreign enemy once, you have to endure countless false activations. Can such a mechanism technique really be called a good mechanism technique?
Thinking of this, Ye Wumian couldn't help but talk too much. He looked at Brother Wang Pan and said: "Brother Pan, sister, I hope you can use it for the right path after learning the mechanism."
Wang Pandi held the child in his arms, and still bowed to the night, and solemnly promised: "Brother Zizi taught you this. When the Master talked about the chapter on King Hui of Liang, he also said that when a person kills with a knife, it is the person who kills, not the knife. . In the same way, the quality of mechanism skills all depends on the person who uses it. I hope that I will live up to my brother Zizi's instructions."
Seeing her sincere expression, Ye Wumian nodded happily.
