In his sleepless heart, he had regarded Chu Yan as the embodiment of a wise man, and when he encountered a problem, he subconsciously wanted to ask her as soon as possible.

Even the question of the mechanism technique was asked to her, not to Wang Pandi.

He had a kind of dependence on Chu Yan invisibly, and he didn't realize the slightest, but it actually existed.

Before Chu Yan could answer, Wang Pandi had already said: "If you want to open this stone gate, when it is difficult, it will be like the blue sky!" When it is easy, it is like probing for things. ”

Ye Wuxian smiled and said: "Brother and sister Pan, since you know how difficult it is, you must already have the means to open this stone door, you might as well say that you will come out, we opened the stone door earlier, and leave quickly, it is always better, stay in this stone room, choking is almost suffocated!" ”

After the fierce fighting, the stone room was embarrassed, not to mention, the air quality had reached enough to help people's lungs.

The situation would be even worse if there were no holes in the walls to evacuate gases and facilitate internal and external circulation.

Wang Pandi said confidently: "I already have a solution, but I don't talk about the principle. Brother Zizai, Sister Yan'er, if you can trust me and only do what I say, this stone door will be opened! ”

Sleepless at night, I couldn't help but think that the expression "If you can trust me", Wang Pandi also said it once before, which can be regarded as her mantra.

Recalling this mantra and thinking of the environment in which she lives, I feel a little sorry for her sleepless night.

She grew up in a family that was not favored and lacked trust, and it was normal for her to put this phrase on her lips.

Sleepless smiled heartily and said, "The three of us, who have experienced what happened tonight, can be regarded as friends of life and death with the same tribulation. If I don't even believe you, then who should I believe? Just say that we will do what you say. You also have to elaborate on the principle. ”

Chu Yan also nodded and said, "What Childe said is exact." Brother Pan, you can also use this to teach us some of the wonders of the technique, the so-called teaching and learning, that is. ”

Seeing that the two brothers and sisters were so encouraging her, Wang Pandi's little face was flushed with excitement, where could he still hold his words, pour beans, and tell the principle.

As Wang Pandi said, as soon as Kong Fangxiong and others died, the organ was activated, and if the reason for the manipulation of a third party is ruled out, there is only one.

"Unless there's an eye here, staring into the stone chamber at all times. Once it discovers what happened to the stone chamber, it will pull the clasp and activate the mechanism! Wang Pandi said firmly.

The eyes of the organs are different from the human eyes.

The human eye can only capture images, and the eyes of the organs, most of them, observe the environment around the organs by capturing smells, so as to determine whether they meet the conditions for the activation of the organs.

Sleepless at night wondered: "This is strange!" How can a device capture a smell without a human nose? ”

Wang Pandi said with a smile: "The organ is dead, but we can't feel the smell, but we are organ scholars, and we usually use insects." ”

"Bugs?"

In the ignorant eyes of the sleepless night and Chu Yan, Wang Pandi calmly walked to a hole in the wall, glanced inside, and then showed a smile of "Sure enough, it is not as Miss Ben expected".

She beckoned: "Brother Zizai, Sister Yan'er, you all come and see!" ”

Sleepless and Chu Yan glanced at each other, and then walked over together, and under the guidance of Wang Pandi, they looked into the hole.

This hole is the hole that Sleepless Night saw before, which is used for indoor and outdoor air exchange.

When I came in before, I only saw the fan-shaped hinge at a cursory glance, but now that I look closer, I have goosebumps that have been sleepless all night.

But when I saw it, it was densely packed with flies.

Those flies were making a fuss and were actively trying to fly indoors, but they were all blocked by something, and they couldn't fly out no matter how hard they fluttered.

It turned out that an iron net was arranged on the mouth of the hole, and its mesh was very thin and arranged even more closely, and if you don't look carefully, you are afraid that it is easy to ignore.

It is this fine iron net that keeps the flies from flying out.

Wang Pandi smiled: "Is the function of this iron net just to prevent flies from coming out?" ”

Sleepless Night said very face-savingly: "Otherwise? ”

Chu Yan covered his nose and mouth, moved away, and said: "Childe, look, on the one hand, the iron net is certainly blocking the flies, and on the other hand, it is inevitable that it will also be hit by the flies. ”

Needless to say, sleepless at night has already been discovered.

After this observation, Sleepless Night instantly understood the principle.

Wang Pandi pointed to the hole, confident, and explained: "Inside the hole, there is a group of flies, they are very sensitive to the smell of blood, once they smell the smell of blood, they will follow the smell and fly over. But the person who designed this mechanism is my mother......"

At the mention of Wang Moshi, her voice lowered, and she didn't regain her strength until she saw the encouraging eyes of the sleepless night.

continued: "My mother put the flies in the hole, and her purpose was naturally not to let them escape, but to use their sensitivity to the smell of blood, and in the process of flying to the source of the smell, to hit the iron net. When the iron mesh is hit, it conducts a signal, and the mechanism is activated. As a result, we saw the sudden closure of the stone door and the sudden madness of the nurse attacking us! ”

Finally, she concluded: "So, these flies are what I call the eyes of the mechanism, and the iron mesh is the machine buckle. ”

After listening to this detailed explanation, I went to other holes at night without sleep, and looked at them one by one.

Sure enough, in every hole, there was a nest of flies, and these flies were still hitting the iron net.

It's just that now that the mechanism has been activated, the nurse of the mechanism has been destroyed by the sleepless night, and even if the iron fence is broken, the mechanism will still remain active, and nothing else will happen.

"Lingtang is a genius in the machine!"

Sleepless sighed from the bottom of his heart.

When he first saw this hole, he only thought that it was just a ventilation device, and even if he had the idea of extending, he was curious about what the power source of those shafts was in the hole.

Who would have thought that there is still such a curved road!

As for using the smell of blood as an introduction, the sensitivity of flies to the smell of blood is used to trigger the mechanism...... If you hadn't seen it with your own eyes and experienced it yourself, even if others talked about it, you wouldn't have been able to sleep at night!

"It's a great idea to put flies in holes."

Chu Yan also said: "The hole is a ventilated place, but there is a smell of blood, and flies must be able to quickly smell it and hit the net to activate the mechanism." Moreover, the rotation of the shaft in the hole conceals the sound of hitting the net, how can ordinary people guess that the doorway of this mechanism is actually in it? ”
