The pellet was supposed to be bonded together with a very corrosive powder, which would be highly hot and corrosive when it came into contact with water.

The old man brought the cup, poured the water in the cup into the keyhole, and heard a loud noise, the water that had just been poured into it boiled instantly, and a large number of bubbles came out of the keyhole.

And the snorting sound should be the movement of the inside of the keyhole being corroded.

When the keyhole was no longer bubbling, the old man took out a very thin pair of tweezers from the drawer and used the tip of the tweezers to dig through the keyhole a few times.

When he pulled out the tweezers, he saw a black flocculent patch between the tweezers.

After this, the old man brought another valve lamp and used it to look carefully into the keyhole for a moment.

At first, he had a look of great anticipation on his face, but soon, the expectation turned into disappointment.

The old man let out a long breath of helplessness and collapsed in his chair.

It was clear that he wanted to open the black box, and had tried many times, but failed.

He sat motionless, staring blankly at the door, as if he were thinking about something, and as if he had completely emptied his brain.

The old man's mind was decadent and calm, and I didn't know what he was thinking.

It was about five minutes before he slapped the armrest of his chair with both hands, got up and left the archives, the black box sitting on the table, and the old man hadn't even put it away.

Seriously, I want to know what's hidden in the black box.

It wasn't until the old man's footsteps finally disappeared at the end of the porch that I sat down and took a closer look at the black box.

In terms of mechanical arts, there are indeed two powerful masters in the industry, but unfortunately I have no research on this craft at all, holding the box in my arms, looking at the extremely hard box wall, my heart is also uncomfortable.

Damn, I can't do anything about it!

But self-pity can't solve any problems, and I'm going to change my mind and try to see if I can change the aura in the box.

Even a disciple of the Human Sect like me can sense the majestic yin qi that permeates the box, which shows that the amount of this yin qi is extremely huge, maybe, this aura is the key to opening the box?

It's not completely unfounded for me to think so, the old man just now in order to open this box, obviously tried to hate the way, but failed, the way he can try is nothing more than to use physical or chemical means to open the box cover, physical means can't hurt it, chemical means can't dissolve it, there is nothing in this world that can't be destroyed, when physical means and chemical means can't destroy it, then you can only use the energy field to stimulate it.

And the aura is precisely a special kind of energy field.

Since the yin qi can penetrate through the box, other qi will definitely be able to seep into it!

I condensed a mouthful of mental power, took a three-immortal talisman, first slowly urged the talisman, so that the talisman rhyme was evenly wrapped on the surface of the box, and then mixed with the mental power in the talisman rhyme, and waited until the telekinesis was evenly spread out on the surface of the box, I mobilized the spiritual rhyme around my body, and slowly pressed the talisman mixed with mental power into the inside of the box.

At that time, I did this out of luck, and I thought to myself, if this box can't be opened, there will be no loss for me, but if it does, maybe I will make money.

Who would have thought, as soon as I started to mobilize the spiritual rhyme of my body, I heard a small "click" sound from the box.

It sounded like the sound of a gear spring.

I was shocked, it wouldn't be so easy to open, would it?

Although I thought so, my hand immediately broke the edge of the lid and lifted it gently.

It's really opened!

Looking at the lid that had been lifted with almost no resistance, my whole mind was confused.

It felt like the mechanism in the box was originally intended for me, and it started not because I found the right way, but because I was the one who opened it.

This feeling scares me.

It's like the fear that the Golden Back Wat brings to me.

Sizzle

As soon as the lid of the box was opened, I heard a slight sound coming from inside the box cavity at this time, and when I looked down into the box, the shock in my heart was suddenly magnified twice.

To be exact, I was shocked twice just by looking at it.

The thing that the old man had just stuffed into the keyhole was indeed corrosive, and there were large erosion marks on the inside of the keyhole and the inside of the box, but at this time, the erosion marks were gradually shrinking, just like the wounds on a human body were slowly shrinking and healing.

That black box, is it possible that it is also a living creature!

And that's not the most surprising thing for me, what really caused my heart to tremble was what was in the box.

A fingernail-sized, gold-and-white bone fragment!

I am too familiar with the aura of the Golden Back Bone Wat to be sure in a split second that the contents of the box are fragments split from a certain Golden Back Bone Wat!

Staring at the contents of the box, I was shocked, and then confused.

It felt like someone had a slap on the back of my head, and it made me feel like I couldn't recover for a long time.

I don't know how long it has been, but when I came back to my senses, the hand holding the box was a little numb.

Why do the fragments of the Golden Back Wat appear here? Why fragments?

This thing is a fake corpse left by the autopsy immortal, who has the power to smash it?

What's going on with this black box, it looks like it's a dead thing, why does it have such a strong self-healing ability, and why even if the lid of the box is opened, the yin qi that creeps inside still doesn't come out?

Countless questions echoed in my head at the same time, and I couldn't find a reasonable answer to each of them.

I took a deep breath to calm my mind quickly, and although my mind was not yet clear, I was able to take out a clean handkerchief from my backpack as quickly as possible, and carefully wrapped the bone wat fragments with it, and then carefully placed the bone wat and handkerchief together in a waterproof and fireproof cinnabar box.

Although the Golden Back Bone Wat does make me feel frightened, after all, this is the treasure of our Xiaolongtan, and I can't let it fall into the hands of others.

After that, I closed the lid again, and the yin qi in the box trembled slightly, and then spread evenly throughout the box, and when the yin qi stabilized, the lid was locked again.

Looking at this thick black box, I thought that this thing, if put to good use, should come in handy.
