I quickly turned around, only to find that there was nothing behind me. I took a deep breath and slowly took a step back, and at this time, I heard Xiaobai let out a whining wail.

I gently touched Xiaobai's head with my hand, barely calmed Xiaobai's emotions, and pushed the piece of meat in front of it: "Eat something, I know you must be hungry now." ”

I was worried that Xiaobai's appetite would be too good after 'strenuous exercise', and the only bit of leopard meat left on my body was not enough for him to stuff between his teeth, but I didn't expect that Xiaobai wouldn't eat at all. It's just a wilting look.

Although Xiaobai is just a wolf cub, he has never made this appearance for no reason, I picked Xiaobai up and put it back into the bag: "Okay, okay, it's okay." ”

After comforting him, I continued to walk forward, and soon, the underground passage in front of us slowly became wider, and I stood still and looked around at my surroundings. Suddenly, I realized that I seemed to be back to where I had been.

No, when I was walking just now, the passage in front of me was obviously straight forward, how could I go back to the place I just had?

I frowned, the wooden sword was now gone, and the rune paper had all been used up, and now I could say that I was barehanded. I looked back at Xiaobai next to me: "Do you feel that something is wrong?" ”

Xiaobai is not an ordinary wolf cub, it can now communicate with me through movements, eyes and whining, after hearing me say this, I found that Xiaobai's eyes also looked confused. After about a few seconds, I saw Xiaobai stir, as if he wanted to jump out.

I paused for a moment, and quickly released Xiaobai, and saw Xiaobai running to the corner of the wall next to him, cocking one hind leg, and starting to pee.

I couldn't help laughing, this little guy just wanted to go to the toilet. Wait, something is wrong, go to the toilet...... I understand that Xiaobai doesn't just want to go to the toilet, it wants to help me mark this place.

"Got it, I'm going to do something too." As I spoke, I searched for a moment inside my shriveled satchel and found a small bottle of cinnabar, which I took out and rubbed little by little on the ground below.

"That shouldn't be a problem." I muttered a few words to myself, then carried Xiaobai back into the satchel, and then continued to hurry forward with Xiaobai.

This time, we sped up, and after about twenty minutes or so, I heard Xiaobai under the satchel whining, and I looked down at Xiaobai: "Could it be that you're back again?" ”

This time, Xiaobai nodded directly and answered my question clearly. I turned around and lit the ground under my feet with a torch, and after looking for a moment, I saw the cinnabar I had just smeared on the ground.

That's right, we're back! What the hell is going on!

I looked ahead and couldn't help but start to feel a little flustered, but soon, I calmed down and silently recited in my heart what Zhang Yang had told me before: "Don't mess up, the more critical the moment, the more calm you must be." Use your brain, don't just know how to move your muscles. ”

Thinking of this, I try to make myself as reminiscent as possible of what I had learned about the Ecstasy Array before. This Ecstasy Array, like other formations, needs to be presided over and injected with energy. But this place, the devil knows if no one has been here for hundreds of years.

Who can continue to inject energy into this ecstasy of birds that don't for hundreds of years? If not, then this is not a Ecstasy Array that relies on Dao Method, but a simple spatial puzzle constructed through the technique of Qimen Dunjia.

Such spatial puzzles, to put it simply, are actually using various deviations in the human senses to create illusions, and when the illusions are superimposed one by one, they will produce staggering and unbelievable results.

Thinking of this, I slowly crouched down and continued to search inside my satchel for a moment, finding a rope.

This is not the mulberry rope we used to use to tie up ghosts, but the straw rope that I used to use the grass leaves scattered next to the beach in the days when I was recuperating from my injuries on the beach behind the pool.

I didn't have an accurate measuring device, so I had to use the soles of my feet as a standard, and mark the scales with cinnabar on them in turn, and make this rope into a suggested soft ruler.

After I made it, I handed the rope to Xiaobai: "Bite tight." ”

The bag understood me and bit one end of the rope, and I pulled the other end of the rope to the other side of the cave, and finally found the midpoint of the cave passage.

At this point, I removed a small string of accessories from my arm. These so-called accessories can be called the 'Swiss Army Knife' of the Heavenly Master Realm. A string of small ornaments that look varied, in fact, each one is a very practical gadget.

I found a shiny brass hexagoprism, and then I took a round iron ring with a thumb-sized concave lens inlaid inside.

The two mirrors, according to their respective focal lengths, were arranged back and forth, and then the torches were placed behind, and I let Xiaobai stand on the other side, and we were a wolf blocking the firelight on both sides, and then, the beam that leaked through the middle passed through the two lenses, and suddenly gathered together and became a slender beam.

This is not a Taoist technique, to put it bluntly, it is actually to use a lens to concentrate the direction of light first, which is just a very simple physical phenomenon. In the view of the Taoist Law School, Taoism has never been a mysterious and mysterious thing, deceiving gods and ghosts, and the technology derived from modern physics can also be used by us.

I looked at Xiaobai and said, "You stay here and watch our torches carefully, I'll go and take a look, and I'll be back soon." ”

Xiaobai nodded with a whimper, walked behind the torch, and looked at the sides, I was amused by the appearance of this little guy: "Okay, don't be so nervous, just watch it well." ”

After saying that, I turned and ran forward, and soon I realized that the passage was straight, and the beam was naturally straight, and the source of the beam was in the middle of the corridor, but now, the beam hit the wall on the right.

In other words, the whole passage is inclined to the left!

I frowned, took a deep breath, used cinnabar to mark the outline of the beam on the wall, and then turned back to the place I had been.

However, when I came back, I found that Xiaobai was gone!
