Once upon a time there was a demon pass

inside the cave.

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

Only then did he look around.

The cave is a bit dim, but it can still be seen clearly under the light from outside.

The cave is not big, surrounded by wet rock walls.

Occasionally there are drops of water dripping.

It is reasonable to say that the hole hidden in the waterfall will be relatively cold, but this cave is very warm.

Wisps of hot air continued to emit in the cave.

The walls are inlaid with red crystal stones. The material cannot be seen, but there seems to be flames constantly jumping inside.

Sway gently.

And in the innermost part of the cave, there is a smaller space, but it is covered 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 brightened.

It looks like...it looks like it's worth a lot of money.

It's just that I still don't know the function and value of this thing.

Going back this time, it seems that I have to catch up on the information about various natural treasures.

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

The sound of fighting outside was still echoing.

It sounded like Xiaojiao's voice had become weak, lacking in energy.

Yu Sheng gradually accelerated the speed.

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

Even the bony dagger had a tendency to melt gradually under the high temperature.

one, two...

In 10 minutes, four daggers were changed.

Finally, the six crystals on the wall were dug out and stored in the mountain and river bottle.

And with the disappearance of the spar, there was a hint of coolness in the cave.

Yu Sheng walked to the depths silently.

Looking at the space around the corner, he turned on the flashlight of his phone and shone inside.

Immediately afterwards, the figure stopped in place.

there, it seems...

It's a coffin.

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

Very rich.

Yu Sheng frowned slightly, and slowly approached the coffin.

He looked into the coffin.

A mummy was lying quietly inside at this time. The corpse had long since lost moisture and was completely air-dried.

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

During the period, Yu Sheng thought about using the mountain and river bottle to prove whether the person in the coffin still had the breath of life.

But this coffin is completely connected to the ground.

Not even a place to open the coffin.

After pondering for a few seconds, Yu Sheng took out the Shanhe bottle and kept searching.

First, he took out an axe, made two gestures at the coffin, and then let it go.

Next, knife, hammer...

After trying one by one, the coffin turned out to be extremely hard.

Even if Yu Sheng used all his strength, he couldn't knock down even a tiny bit.

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

No need to think about it, this coffin must be a good thing, and it may even be the most valuable item in the Shenxuan.

but...

can't take it away...

The unbelievers of the rest of my life are still trying.

The sounds from the outside world have gradually become weaker, as if the battle has ended.

Vaguely, Yu Sheng looked through the crystal coffin and saw the mummy's hands clenched tightly, as if he was holding something.

Constantly comparing the position of the hand.

Yu Sheng carefully took out a blood-red spar dug outside, stuck it above his arm, and looked at it expectantly.

It was like putting a fire on ice.

The spar was shrinking at a speed visible to the naked eye, and a hole was also scalded in the crystal coffin.

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

About the thickness of a finger.

Yu Sheng carefully took out a crossbow arrow, stretched it into the hole, and gently lifted the mummy's palm to reveal the contents inside.

It is a jade medal.

The small white jade pendant is round, with a very complicated pattern printed on it, and there is no energy fluctuation in it, so it is ordinary.

I always feel that compared with the blood-red spar, it is a blood loss.

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

finally...

stuck in the hole.

Can't get out.

The hole, which is as thick as the index finger, is still too small after all.

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

But this thing...

Is it really worth three blood crystals?

Yu Sheng just fished for the jade pendant, stuck it on the wall of the crystal coffin, and observed it carefully.

And then... didn't understand anything.

Can't recognize it.

So far, all the items in the Demon Realm, it can distinguish, only the Demon Crystal and Demon Core.

leftover...

Judging entirely by the reactions of other monsters and the energy emitted by the item itself.

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

It looks more shiny.

This is the law that Yu Sheng has summed up recently.

But this jade badge...

No waves.

Compared with the gleaming blood crystals, it's 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?

Hearing the sound of fighting again from outside, Yu Sheng was stunned for a moment, apparently still unclear about what happened.

Obviously just played a game before.

After thinking about it for about 30 seconds, Yu Sheng finally put down the jade tablet silently and pulled back the fishing line.

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

Just now, Yu Sheng suddenly figured out a truth.

If he gave up at this point, it would be equivalent to losing a blood crystal 100%, without any reversal.

But if you insist on taking out the jade pendant, there is still a possibility of turning the tables, or... losing three pieces.

But at least there is some hope for the latter.

It won't be enough to lose out.

Seeing the widened and lengthened opening, the action went much smoother this time. The first time it was raw and the second time it was cooked, it was easy to hook the fishing line on the jade pendant and pull it out along the opening.

Just the right size.

If the position of the punching hole is slightly skewed, I am afraid that another one will be wasted.

I fiddled with the jade token, especially felt it carefully with my breath.

Um...

Just ordinary.

Whether it's the breath or the material.

Yu Sheng even felt that he could crush it with a little force.

At this time, his peripheral vision fell on the crystal coffin.

It seemed that some viscous liquid had scalded out of the place where he had just punched the hole.

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

There is a faint tendency to drip.

Yu Sheng put away the jade plaque resolutely, took out a small knife, scratched it lightly, and finally put it in a porcelain vase.

It is full of energy breath.

Very pure.
