Inside the cave.

Yu Sheng watched this scene calmly, and carefully recalled the perception of the moment he just entered the cave.

Then he looked around.

The cave was a little dim, but it was barely visible in the light outside.

The cave is not large, and all around it are damp rock walls.

Occasionally, water droplets are dripping.

Logically speaking, the entrance to this cave hidden in the waterfall would be relatively cold, but the cave is very warm.

Wisps of heat continued to emanate through the cave.

On the walls, there are red spars, and I can't see any material, but there seems to be flames jumping inside.

Gently swaying.

And in the innermost part of the cave, there is a smaller space, but it is hidden and cannot be seen clearly.

Yu Sheng lightly touched the red spar with one hand, but under the high temperature, he directly retracted his hand.

For a moment, his eyes were a little bright.

It seems like... Looks like it's worth a lot of money.

It's just that I don't know what this thing does, what it value.

When I go back this time, it seems that I have to make up for the information about all kinds of natural treasures.

Yu Sheng took out a bone dagger and kept digging in the wall.

The sounds of battle outside continued to echo.

It sounded like the young Jiao's voice had become weak, and his qi was insufficient.

The rest of your life is gradually increasing at a faster pace.

The rock is extremely hard, and it takes a lot of effort to dig up a hedron.

Even the bony dagger had a tendency to melt in the heat.

One, two...

Ten minutes, four daggers were replaced.

In the end, the six spars on the wall were dug up and stored in the mountain and river bottle.

And with the disappearance of the hedrons, there is a hint of coolness in the cave.

The rest of his life silently walked into the depths.

Looking at the space around the corner, I turned on the flashlight of my phone and shone it inside.

Immediately after, the figure froze in place.

There, it seems...

It's a coffin.

The whole body of the coffin is made of crystal, translucent, and even the surface of the coffin is constantly exuding energy.

Unusually rich.

Yu Sheng frowned slightly and slowly approached the coffin.

Look inside the coffin.

A dried corpse was lying quietly in it at this time, the corpse had long been out of moisture and was completely dried.

I don't know how many years I have been here.

During the rest of his life, he thought about using the mountain and river bottle to confirm whether the person in this coffin still had the breath of life.

But the coffin is completely connected to the ground.

There wasn't even a place to open the coffin.

After groaning for about a few seconds, Yu Sheng took out the mountain and river bottle and kept rummaging through it.

First, he took out an axe, gestured twice at the coffin, and then let it go.

Immediately after, knives, hammers ...

I tried them one by one, but the coffin turned out to be extremely hard.

Even if he used all his strength for the rest of his life, he couldn't knock down even the slightest.

I can only feel the pure energy that is constantly emanating from it.

You don't have to think about it to know that this coffin must be a good thing, and it may even be the most valuable item in the Divine Ruins.

But...

Can't take it away...

For the rest of his life, those who don't believe in evil are still trying.

The sounds of the outside world had gradually become fainter, as if the battle had ended.

Vaguely, through the crystal coffin, Yu Sheng saw the hands of the dried corpse inside clenched tightly, as if he was pinching something.

Keep comparing the position of that hand.

Yu Sheng carefully took out a blood-red spar that he had dug up outside, and put it on his arm, looking at it with some expectation.

It's like a fire on top of an ice cube.

The hedron was shrinking at a visible rate, and the crystal coffin was also burned out of a hole.

In the end, at the moment when the spar energy completely disappeared, a small opening was finally made in the crystal coffin.

It's about the thickness of a finger.

Yu Sheng carefully took out a crossbow arrow, reached into the hole, and gently opened the palm of the dried corpse, revealing the contents inside.

It's a jade plaque.

A small white jade pendant, round in shape, with a very intricate pattern printed on it, without any energy fluctuations, unremarkable.

I always feel that compared to the blood-red spar, the blood is lost.

Yu Sheng retracted the crossbow arrow, wrapped the fishing line in a small circle, and passed it along the hole, his hand was very steady, and he slowly circled the jade plaque and slowly lifted it upwards at a steady speed.

Ultimately...

Stuck in the hole.

Can't get out.

The hole with the thickness of the index finger is still too small after all.

If you want to take out this jade plate completely, you need at least two blood crystals.

But this thing...

Is it really worth three blood crystals?

For the rest of his life, he fished for jade pendants, pasted them on the wall of the crystal coffin, and observed them carefully.

And then... Didn't understand anything.

Unrecognizable.

Up to now, all the items in the Demon Domain, all it can distinguish are the demon crystal and the demon core.

The rest...

It is completely judged by the reactions of other monsters and the energy emitted by the item itself.

The more awesome something is, the more compelling it is.

The more it looks.

This is the pattern that Yu Sheng has summed up in recent times.

But this jade card...

No waves.

Compared to the glittering blood crystal, it is not at the same level at all.

Perhaps, it was just a small object that the owner of the coffin took before he died?

Just have a special meaning?

Listening to the sound of fighting and fighting coming from outside again, Yu Sheng was stunned for a moment, obviously not knowing what was happening.

Obviously, I've just had a fight before.

After thinking about it for about thirty seconds, Yu Sheng finally silently put down the jade plate slowly and pulled back the fishing line.

He took out two more blood crystals, picked a location, and threw them on the wall of the crystal coffin.

Just now, Yu Sheng suddenly figured out a truth.

If you give up on this, you will lose 100% of a blood crystal, and there will be no reversal.

And insist on taking out the jade pendant, there is still the possibility of turning the tables, or... Pay three.

But at least there is some hope for the latter.

It will not be pulled down after the loss.

Looking at the widened and lengthened opening, this time the action went a lot smoother, one was born, the second was cooked, and it was very easy to hook the fishing line on the jade pendant and drag it out along the mouth.

The size is just right.

If the position of the hole is slightly crooked, I am afraid that I will waste another one.

Fiddled with the jade plaque, especially carefully felt it with his breath.

Well...

It's just very ordinary.

Whether it's the breath, or the material.

Even the rest of my life felt like I could crush it with a little bit of force.

At this moment, his afterglow fell on the crystal coffin.

The position where I just punched the hole seems to have scalded out some viscous liquid.

It doesn't look too much, just a thin layer.

There is a faint tendency to drip.

Yu Sheng decisively put away the jade plate, took out a knife, gently scratched it, and finally put it in a porcelain bottle.

It was filled with the breath of energy.

Very pure.
