The Jin family dug a slender fire trough on the roof of this floor.
Both sides of the trough and the top of the entire wall were covered with phosphorus powder. powder, the entire floor will be in flames, and the gunpowder buried under the kerosene will explode.
This is an extremely dangerous mechanism.
Once triggered, the two nearby stilted buildings will also be blown up.
The stone slab that Lin'er found on the west wall was the birth gate of the Fire Oil Formation.
I carefully studied the keyhole on the stone slab.
The keyhole-like hole was about the size of a fist.
At first, I thought that this thing could only be opened with a specific key.
Later, when I shined light into it, I discovered that the inside of the keyhole was a very special one.
The deep metal tube is filled with a large number of anchor pieces around the channel.
These anchor pieces are arranged in layers like shark teeth, and the number is difficult to estimate.
At the bottom of the metal barrel, there is a shuttle needle with a cross-sectional diameter of about seven centimeters.
The needle tail must be fixed with something, and the entire needle is suspended in mid-air, unable to contact the surrounding anchor pieces.
It's just that the distance between it and the anchor piece is very close.
At least if it is slightly skewed, it can press on the anchor piece.
I roughly guessed how this mechanism was broken, but I still hesitated a little.
If I wanted to break the kerosene array, I had to pull out the shuttle needle from the keyhole.
The scary thing was that the shuttle needle would hit the anchor pieces during its movement. , then we’re doomed.
This is a delicate job, and I can't do it alone.
Someone has to help me shine the light.
I discussed it with Bai Laogou and the others.
Bai Laogou took the initiative to stay and help me, but after thinking about it, I decided to let He Wenqin stay.
Among all people, he and I have the best light-weight skills.
If something goes wrong, What's wrong?
There's still a possibility for the two of us to escape, but if Bai Lao Gou is allowed to stay, to be honest, I'm not sure I can protect him.
When Bai Laogou led the others to retreat upstairs, he warned me to be careful and give up if I really couldn't do it.
I could tell from Bai Laogou's words that this time he was really afraid that something would happen to me, and he was quite touched.
When Bai Laogou and the others retreated, He Wenqin and I started to take action.
He Wenqin shined the light into the keyhole, and I untied the Bagua Qian, threw the positive thread into the keyhole, and shook my wrist a few times to make the positive thread tightly entangled.
Hold the shed close to the needle.
He Wenqin probably had never seen such meticulous wrist work as San Diaoqian, so he praised me: "Good craftsmanship."
I took a deep breath, slowly turned my wrist, and slowly pulled the shuttle needle outward with the help of the male thread.
As soon as the shuttle needle moved, I heard a "chi la" noise coming from the roof behind me.
My heart trembled and I quickly stopped.
Hand movements.
But at this time, I didn’t dare to let go, let alone look back.
I could only ask He Wenqin: “What’s going on?”
He Wenqin turned around and flicked the light, and quickly responded: "The ignition stone on the roof has moved."
"How did it move?"
"Sliding a short distance to the left, there is a hole on the left side of the stone trough, and the ignition stone is shrinking towards the hole."
I understood that as long as the shuttle needle is pulled out, the ignition stone will leave the stone groove.
That thing is equivalent to the fuse of the kerosene array.
As long as it is gone, no matter how much kerosene is everywhere, it will not be ignited.
What I am most worried about now is that the flint stone will rub against the phosphorus powder on the wall of the tank during its movement.
However, He Wenqin said that the flint stone moved straight and did not touch the phosphorus powder for the time being.

When I took out the shuttle needle just now, I made the needle move straight.
It is estimated that as long as the needle body is deflected, the flint stone will also be deflected when it moves.
Now I have a general understanding of the structure of the fire oil array, but sometimes, the clearer you are about the current situation, the easier it is to become nervous.
Next, during the process of moving the shuttle needle, there seemed to be an invisible pressure on my heart.
A stream of cold sweat flowed down my forehead.
Sometimes the sweat fell into my eyes.
Maintain the stability of the shuttle needle despite discomfort.
He Wenqin took a handkerchief to wipe my sweat.
I found that his palms and backs were also covered in sweat, and most of the handkerchief was soaked with sweat from his hands.
When part of the shuttle needle came out of the barrel, I held the needle in my hand and stepped back as evenly as possible.
The needle was at least one meter long.
I took three steps back before pulling it out completely.
When I took the last step, maybe because of the excitement, my hand was not as steady as before.
The shuttle needle suddenly tilted, and the needle tail hit the edge of the barrel firmly.
Listening to the muffled sound of "clang", my heart almost rose to my throat.
He Wenqin also hurriedly lit the light on the roof.
It was really lucky that by this time, the ignition stone had completely retracted into the left part of the slot.
In the cave.
I carefully placed the shuttle needle on the ground, and then all the turbid air that was pressed in my chest came out, and I immediately started to breathe heavily and out of breath.
When I moved the shuttle needle just now, I was afraid that breathing too hard would affect the stability of my hand, so I often held my breath.
He Wenqin also gasped for breath, and while he was panting, he gave me a thumbs up: "Looking at your young age, your methods are more powerful than those of the Jin family.
Fortunately, you are there, otherwise these institutions left by the old Jin family would probably be No one can break it."
I said: "I don't dare to compare with the people of Lao Jin's family.
To be honest, I may not be able to lay out the mechanisms they designed even if I just copied them."
Bai Laogou probably overheard the conversation between He Wenqin and I, so he stuck his head out from the stairs and asked, "It's done."
He Wenqin raised his head and responded: "It's done.
The little brother you brought here is really powerful, and his techniques are so stable.
Even the heirs of the thieves family may not have such good techniques."
Bai Laogou was stunned for a moment, and then muttered one word: "Humph."
His reaction was as expected.
I smiled helplessly and didn't say much.
After resting for a short while, I invited everyone to walk through the fire oil array together.
Walking on the kerosene, I discovered that there were a lot of gold threads buried under the kerosene.
If the ignition stone had not been removed in advance, it is estimated that as soon as the soles of my feet touched the hidden threads under the kerosene, the entire floor would be ignited in an instant.
I don’t understand the behavior of Lao Jin’s family even more.
If they set up such a mechanism where they live, if something unexpected happens, a family of 100 people will not be able to survive.
What on earth are they hiding deep in the old house, why do they have to use such extreme measures to guard against outsiders?
When walking along the stairs under the east wall toward the third floor, we found a row of shiny footprints on the stairs.
These footprints should be left by the person we saw before.
The reason why the footprints are shiny is because when he passed through the fire oil formation, the soles of his feet were stained with a lot of grease.
This man was not wearing shoes, and his feet were wide.
Most people only have five toes, but judging from these footprints, the other person had six toes, and the big toe grew two side by side.
He Wenqin knelt down and looked at one of the footprints repeatedly, and suddenly said: "They are from our old He family."
Bai Laogou immediately asked him: "How do you know who the He family is?"
"Our old He family can travel all over the world with light body kung fu, just because the soles of each He family's feet are different from ordinary people."

As he spoke, He Wenqin also raised his feet for us to see.
His soles were also very wide, and the toe of his shoe was widened near the thumb.
Bai Laogou said: "Apart from you and He Jiayun, there are other descendants of the old He family."
"I can't figure it out.
Normally, apart from me and Jia Yun, there should be no one else in the family," He Wenqin responded: "Except for Jia Yun who is not with me, I presided over the burial of the other clan members.
But the one I saw just now He always looks very familiar to me, but for a while I can’t remember where I’ve seen him before.”
Lao Ruan interjected from the side: "It can't be your father, right?"
He Wenqin shook his head: "Impossible.
If my father really lived to this day, he would be over ninety years old.
The man's hair just now didn't even have white hair.
He was in his early fifties at most.
Besides, even though I was still young when my father died, , but I always have his photos at home, how could I not recognize him.”
While they were talking, I lit up a cigarette and took a few puffs, trying to calm down my chaotic mood.
After He Wenqin and Bai Laogou said a few words, they collectively fell into silence.
After smoking most of the cigarette, I carefully put out the cigarette butt and asked everyone to continue deeper.
After going down the stairs, the footprints on the ground were still there.
We lit the light in the direction in which the footprints spread, and saw three earthen walls standing directly opposite the staircase.
Each wall was at least half a meter wide.
At first glance, the walls looked like They are straight, but if you look closely, you will see that they are slightly tilted in small increments.
By shining the light along the gap in the middle of the earth wall, you can see that there are large sections of wall in the distance.
Some of the walls are connected at the end.
In other places, there is a gap between the two walls, which is just enough for a person to walk through.
Wood, fire, earth, metal, water, after passing the two formations of wood and fire, this formation must be the earth formation.
The earthen formation in the mechanism technique has only one structure, which is the swamp maze, that is, some deadly swamps are set up in the normal maze.
If you step on the wrong foot, you will be doomed.
But this is on a stilt building.
No matter how powerful the Jin family is, they can't create a swamp in a place like this.
Since it's a maze, it's easy to solve.
Just follow the footprints on the ground and you'll definitely be able to get out.
Unfortunately, I thought too simply.
As soon as I walked in front of one of the earthen walls, I heard the sound of gears turning from deep in the floor.
I could also hear a series of intensive friction sounds, as if something heavy was moving on the ground. .
Bai Laogou asked me what the movement was, and I thought about it before telling him that this should be a moving maze.
You must follow certain rules to get out.
If you don't understand the moving rules of the maze, you will be trapped and die in it.
After hearing what I said, Bai Laogou became a little irritable: "Are you trying to say that you can't figure out the rules here?"
I smiled at him: "Don't bother, let's tear down the wall."
Bai Laogou stared at the three earth walls in front of him and couldn't help but frowned: "How long will it take to demolish such a thick earth wall?"
I walked up to an earthen wall, took a solid lunge, and struck a straight backhand punch.
As soon as the punch touched the wall, with a series of muffled sounds, the earthen wall collapsed into a gap more than one meter wide. of breach.
Bai Laogou curled his lips: "I almost forgot, your master is the second child."
Fortunately, these walls are made of hard soil.
If these are stone walls half a meter thick, it will take a lot of effort to tear them down
