At first, I thought that the old Jin family might put the Shengmen in the tunnel, but I searched the tunnel several times with a flashlight, but I couldn't find anything.

Later, I thought about digging a tunnel through the trap array, but there was a layer of seven-gold stone poured under the floor, not only the floor, but also the walls on both sides of the tunnel and the inside of the zenith were reinforced with seven-gold stones.

I also made a mistake this time, I really don't know how to crack this array in front of me, if I can get in, maybe I can find the location of the birth gate, but the room is full of invisible blades, and I can't get in at all.

The white old dog didn't wait for me to say hello and got into the tunnel, and when he came in, he made a lot of movement, and I knew it was him just by listening to the footsteps, so I didn't look back.

The old white dog came up to me and asked me why it had taken me so long.

I didn't reply, but I took a handkerchief from my pocket, tied it into a pimple, and threw it forward.

This time, the handkerchief left the tunnel completely, but before it could fly far in the air, it was instantly cut into pieces, and as the pieces fell, some of them were repeatedly cut off by the moving knife edges.

The old white dog couldn't see through the doorway in the house, probably in his eyes, the handkerchief that was tied into a pimple was like a sudden burst in mid-air, turning into a big handful of scraps.

"Really, this is?" The tone of the white old dog was very panicked.

I said, "There are a lot of fast-moving steel knives in there, and the edges are very sharp, and it's not an exaggeration to say that the hair is broken." ”

"How to crack it?"

"I haven't thought about it yet."

I sighed sullenly, and then fell silent with the old white dog.

After a long while, Bai Laogou suddenly said: "How did the knife in it move?" ”

He said this completely to himself, but he inadvertently gave me some hints, if the knives in the house want to move quickly, they must need energy and holes, the Jin family can keep the mechanism running for more than sixty years, it is certainly impossible to rely on electricity, I suspect that the power of the mechanism should come from the water power formed by the underground river veins, or with the help of the wind.

In the past, when I read the "Book of Luban", the book said that Luban could build a perpetual motion car, of course, from the perspective of the law of conservation of energy, the perpetual motion machine is impossible to exist, and the perpetual motion car made by Luban is just that it does not need manpower to run, he made a complex wind system in the car, as long as the wind continues to blow inward, the car can keep running forward, but if the wind is weak, the car can not move.

Now we are located in the North Mountain, and if there is a cave in the mountain, and there is a flow of water and a breach in the surface of the mountain, the wind will be relatively strong and continuous.

Thinking of this, I leaned down and pressed my ears to the ground to listen carefully.

At first, I could only hear the surrounding "hehe" noise, but after a long time, I could indeed hear the sound of the wind coming from under the surface, and the Jin family seemed to have dug a large number of wind-and-criss-cross air ducts under the ground, and the wind was very chaotic and urgent.

When the old white dog saw me pressing my body to the ground, he asked me what I was doing.

I ignored him and focused all my attention on listening to the wind.

"There are a lot of staggered and spreading air ducts buried underground, and the direction of the wind flow is very chaotic." After five minutes, I straightened up and said to the white dog.

The white old dog didn't understand what I meant: "Wind duct? What are the Jin family doing installing air ducts underground? ”

I didn't bother to explain, and I extracted the yin qi from the Netherworld Treasure, intending to summon karmic wind and karmic fire.

Originally, I only wanted to draw out two yin qi, but with a slight force, all three ancient coins were drawn out, two yin qi can give birth to karmic wind and karmic fire, and what can three dao give birth to?

I was also a little curious, so the envoy slowly pressed the three yin qi together, and the karmic wind and karmic fire still appeared as always, and there was also a dark Lethe water gushing out along the money hole of the ancient money.

As soon as the Lethe water came out, it was quickly absorbed by my left hand, but this time when it flowed into the five internal organs through the heart veins, it failed to replenish my mental power.

There are still a lot of things that I haven't figured out about this Lethe water, and I can't tell why it has become different from last time.

Besides, now is not the time to study these, and I first drove the karmic fire into the zenith and then the karmic wind into the ground.

This is the first time Bai Laogou has seen the karmic wind and karma fire, the last time I used the karmic fire to bake charcoal, only Lin'er and Lao Ruan saw it, Bai Laogou's mind at that time was all on the ancient mother-in-law, how could he have the energy to pay attention to me.

The heat wave directly burned the stone on the surface of the zenith into powder, and a large amount of solid ice condensed in the place where the karmic wind blew, and the white old dog was suddenly shocked: "What kind of technique are you using, you can summon ice and fire out of thin air." ”

The yin qi in the karmic wind cannot be sensed, and in the eyes of the white old dog, isn't it just summoned out of thin air?

I didn't respond much, but asked the old white dog to be silent for now, because I had to listen carefully to the wind underground.

I felt that the air duct was not too deep into the ground, and the karmic wind was strong enough to build up ice in it, so that the wind could be stopped.

The wind tunnel was indeed blocked by ice, and the sound of the wind quickly disappeared from the ground, and the knife edge in the room slowly stopped moving.

But just as I was about to catch my breath, there was a sudden sound of wind from the ground, and the knife edge, which had just seemed to be about to stop, began to flash rapidly.

It seems that there should be a hidden backup power source underground, which is very deep into the ground, and the karmic wind cannot be suppressed.

However, this backup power source doesn't seem to be so easy to use, and the wind under the ground is much stronger than just now, but the speed of the knife edge movement is much slower than before.

Only then did I see that there were thirty-six steel knives in front of me, each of which was the same length as the width of the room, and the left and right ends of the blade were fixed to the rails on the wall.

The shape of these tracks is wavy, and the thirty-six waves on each wall are combined to form a nine-day Milky Way map, two walls, a total of twelve waves.

This structure is called "heaven and earth are positive and negative", thirty-six Tiangang, seventy-two earth evils, can be converted back and forth between each other, look at those steel knives that move along the track, but also sometimes go up, forward, sometimes down, backward, when going up on behalf of the yang floating sky, corresponding to Tiangang, up and down on behalf of the yin energy into the ground, corresponding to the earth, each knife dynamics, speed, there are slight differences, it is difficult to grasp the law.

As soon as the nearest knife to the tunnel had risen to the zenith and had not yet fallen, I quickly poked my head out and glanced towards the center of the zenith.

Normally, in the structure of the "Heaven and Earth Positive and Negative" mechanism, there will be a push-pull valve that symbolizes the "primordial", and when I looked closely at the center of the zenith, I saw that there was indeed a pull ring inlaid in that place.

Speaking of the old Jin family's tricks, when the knife edge moved fast just now, not only could I not see the knife edge, but also could not see the track on the wall and the pull ring on the zenith, as if the knife edge formed some kind of weird visual blind spot in the rapid movement, just blocking these things.

I didn't dare to stay longer, so I quickly retracted my head after a glance, and as soon as I shrank like this, the pull ring on the zenith was no longer visible.

The white old dog asked me anxiously: "How is it, can it be broken?" ”

I said, "If you can break it, you can break it, but you have to let He Lao do me a favor." ”

The white old dog immediately beckoned back: "Lao He, come here and do me a favor!" ”

He Wenqin came in immediately, and I didn't rush to let him move, but sat on the edge of the tunnel and watched the knife cuts in the room, trying to see through their movements.

To be honest, as long as you can see through the structure of the mechanism, it is not a problem to see through the movement of the knife edge, but the problem is that it takes time.

The speed of the knife flickering was still too fast for me, and I stared at them for a long time, and the tears were almost gone, and I couldn't see a doorway.

It wasn't a way to go on like this, so I thought about it and decided to break through.

I wrapped the yang thread around the palm of my left hand, and wrapped the teeth and gossip money together, so that I could have an extra layer of protection, and then I took He Wenqin towards the center of the house, and the white old dog gave us light in the back.

When the two of us stepped out of the tunnel, the nearest knife had just reached the zenith, but when we landed this foot, it fell quickly.

As soon as I saw the knife falling, I immediately raised my left hand and used the palm of the Yang line to catch the knife, which is really dangerous, because you don't know how heavy the steel knife is, and you can't count how fierce it falls, the Yang Line should be able to block the blade, but if the knife falls too violently, just smashing it can also smash me to death.

As long as I feel that the situation is not right, I will immediately pull He Wenqin back, He Wenqin is not standing under the knife, he will definitely not die, as for whether I can withdraw, it depends on luck.

Thankfully, the edge of the knife was just sharp, but it was still bearable, and I could make it stop immediately as long as I put all my strength into it.

As long as the knife stopped, there would not be much pressure, so I asked He Wenqin to walk between the two knife edges first, and then spread Tengyunbu to follow up.

After eighteen knives in a row, we finally came to the middle of the room, and when we looked up, there was the fist-sized ring directly above our heads.

He Wenqin lit up on the pull ring: "This thing must be three stories above the ground, how can you touch it?" ”

I also looked up at the zenith: "I lassoed it with a yang thread." He Lao, as long as I pull the pull ring, you will quickly knock me down, and as long as the pull ring moves, you will pounce. ”

He Wenqin didn't seem to understand what I wanted to do, but he still nodded: "Listen to you." ”

I took a deep breath, calculated the distance of the pull ring, and then spilled the yang line, the gossip money was passing through the pull ring, and the yang line circled around the pull ring three times, and the pull ring was firmly covered.

He Wenqin was ready to pounce, and I didn't hesitate any longer, my arm sank, and I pulled the ring violently.

Recently, I've been quitting smoking, and the efficiency is a bit low, and the daily update time will be slightly delayed, so please bear with me.
