After Haosheng was amazed, he asked Wang Pandi sleeplessly: "So, Brother and Sister Pan, after seeing through the eye of the mechanism and the machine buckle, how do we open the stone door?" ”

Wang Pandi said: "This is easy. According to the common idea in the "Brief Book of Organs", it is enough to close the eyes of the organs. ”

As she spoke, she pointed to the flies in the hole and said, "As long as we cover up the smell of blood, the flies will stop." As soon as the flies stopped, the barbed net was no longer hit. The clasp is no longer stimulated, the mechanism closes naturally, and the door opens. ”

There is nothing wrong with this idea, but Chu Yan has another layer of worry.

Of course, this is based on the premise that the mesh as a buckle should be reusable. If the wire mesh machine buckle is invalid after triggering the mechanism, we know this principle, but it is also in vain, and we cannot make the mechanism close. ”

Looking at her worried look, Chu Yan comforted: "Brother Pan, I said before that the machine buckle in this stone room will not be a one-time one. I wasn't sure before, but now that I've heard about flies hitting nets, I'm completely sure. ”

Sleepless nodded his head.

Think about it, flies are certainly attracted to the smell of blood, and they may also be attracted to other smells.

When the smell of blood is permeating, it means that there is danger in the stone room, which causes flies to hit the net, and the engine is turned off, which is no problem.

But what if other smells, such as the smell of food, trigger the activation of the mechanism?

In this case, there is no danger, and you have to find a way to close the mechanism.

In this way, the buckle that triggers the activation of the mechanism must not be a one-time one, otherwise once it is activated by mistake, wouldn't it be to shut yourself up alive in the stone chamber?

Chu Yan said with a smile: "Actually, the probability of this mechanism being activated by mistake is quite large. If you don't believe it, look at this torch. ”

Sleepless at night, he looked at the lighting torch that Chu Yan was pointing at.

There was some mud on the handle that didn't jump on the flames.

After careful study, I found that this mud was nothing else, but the remains of flies, scorched and piled together, which gave it such a disgusting appearance.

"When the mechanism is activated by mistake, the best way is not to cover the source of the smell, the source of the smell is covered, but the flies have a memory, and most of them will linger on the tempting smell and continue to hit the iron net, so the mechanism must not be suspended."

Chu Yan pointed to the torch and said, "The best way, of course, is to raise the torch and burn the flies through the iron net." The flies died, and on the iron net, the impact force was gone, and the mechanism didn't have to wait a while, and the rotation stopped. ”

At this time, I also found that the iron mesh of the ventilation hole was black and dark, and there were indeed traces of burning, and even the iron net of a certain hole was still stuck to the remains of some flies, which seemed to be caused by not being burned clean.

"That said, this mechanism is too cumbersome, not to mention that it can be activated by mistake from time to time. After burning the flies, in order to maintain them in the future, they have to be replaced with flies all the time. Sleepless complained at night.

Chu Yan said: "Childe, it is actually necessary to change flies, if it is always the same group of flies, smelling blood but not flying out, over time, and learning to be smart, I will give up hitting the net." At that point, the mechanism will be useless. ”

Seeing that Chu Yan was not a scholar of mechanical arts, but he was able to explain all aspects that he had not expected in such detail, Wang Pandi praised: "Sister Yan'er is smart and is a good material for learning mechanical arts!" ”

Chu Yan was praised by her, very calm, and not surprised.

With a slender hand, she removed a torch from the side of the hole and poked it into the wire mesh at the hole.

I could only hear a crackling sound, the smoke was exhausted, the smelly and fragrant smell wafted, the flames were everywhere, and the flies attached to the iron net were half dead at once.

Sleepless at night, he pushed a palm wind in his hand, fueled the flames, and sent them in, and all the flies that flew over the iron net were also burned.

scattered and scattered, many corpses were dropped, all of which were swirled away by the hinges in the holes. There were also a few that stuck to the torches, mixed with the original mud, and were no longer distinguishable from each other.

After burning a hole, he and Wang Pandi went to burn other holes.

If it weren't for the burning of flies, I didn't find it at night, but the arrangement of torches in this stone room was also regular: wherever near the hole, there were torches.

He hadn't thought about it before, but the torches were purely for lighting.

Looking at it now, most of it is also to be able to take the flies and burn them immediately after the mechanism is activated by mistake, so as to stop the loss in time.

One ring after another, step by step design, has never been wasted, but what is done is hurtful to nature.

It's impressive.

When all the flies were burned and killed, the three of them had not yet spoken, and there was a "rumbling" vibration under their feet.

When I looked back after sleepless nights, I saw that the stone door, which had been tightly sealed, slowly opened, and it was restored to the appearance when I entered the stone room.

All three were delighted.

Wang Pandi looked at Chu Yan and said, "Sister Yan'er, I can't praise you too much!" If I follow the method I have described to cover the smell, I don't know how long it will take for this stone door to open. Your method is instantaneous! ”

Chu Yan said: "Thanks to you, you said that you want to open this door, it is as difficult as climbing to the sky, and it is easy to find out when it is easy." We also did a probe tonight. ”

After sleepless nights, he first picked up the three children and walked outside.

All three rescued the toddler and returned to the ground, standing outside the courtyard.

At this time, the sky has become green after dark, the rooster crows in the distance, and the dawn of the seventeenth day of the lunar month is coming.

After this night, I felt sleepless and only in a trance, as if in a dream.

The cognition of the mechanism is not the first time I entered this courtyard, but just blindly surprised and admired, which can be regarded as "disenchantment".

"It's a wonderful technique, and there are a lot of side effects. In the case of the stone chamber, it is possible to activate the mechanism through flies without realizing it to destroy the intruder. But starting by mistake from time to time, I'm afraid it's the norm! ”

Just to be able to destroy foreign enemies once, you have to endure an unknown number of misstarts, can such a trick really be called a good trick?

Thinking of this, I couldn't help but talk a lot at night, looked at Brother Wang Pan and said, "Brother and sister Pan, I hope you can use it for the right way after you have practiced the mechanism." ”

Wang Pandi held the child, and still had a sleepless salute at night, and solemnly promised: "Brother Comfort teaches you a lesson." When the master talked about the chapters of King Liang Hui, he also said that when a person kills with a knife, the murderer is a person, not a knife. In the same way, the quality of the trick depends on the person who uses it, and I hope that my brother should live up to my brother's orders. ”

Sleepless looked at her sincerely, and nodded with satisfaction.
