With a low roar, these resurrected monsters rushed towards Li Xiaofei, constantly releasing all kinds of lightning, frost, and toxins.

Before Li Xiaofei could make a move, the undead bone dragon Ao Ying rushed forward excitedly.

It was a battle between the dead.

Ao Ying used its body and sharp claws to constantly sweep and tear the monsters apart.

Its skeletal body was bombarded by the forces of various elements head-on without damage.

Not for a moment.

All the resurrected monsters were completely swept away by Ao Ying.

Ao Ying was very excited.

He searched for the perfect skeleton among the broken corpses on the floor, and then embedded them into his body like a Lego toy.

It's also evolving.

Evolve by collecting bones.

Li Xiaofei was a little speechless.

The body, which was already very complete and beautiful, looked a bit like a snake after inserting these bones indiscriminately.

But Ao Ying enjoyed it.

It even tried to piece together a pair of bone wings for itself.

But there are not enough bones of sufficient quality, and only a small dot can be pieced together.

It looks ridiculous.

It's as if an eagle has installed a pair of chick wings.

Li Xiaofei came to the depths of the stone hall.

Here's another steel fence gate.

Like the one encountered in the Endurance Temple, this steel fence exudes a strange coercive power, and has protective properties, which are difficult to destroy and hard to chisel.

But the gate on the fence was destroyed.

is on.

No wonder so many Reaper warriors are desperate to stop here.

But depending on the situation, they didn't work out.

The enemy still rushed into the area behind the steel fence.

The rear area is a wide corridor.

Unsurprisingly, corpses were piled up on the road.

Judging from the clothing of the corpse, even if it is already decayed, it can be seen that the reaper who died here has a higher status.

There are closed stone gates on both sides of the road.

Li Xiaofei opened one of the stone doors.

Inside is an enclosed space.

It covers an area of about 500 square meters.

The expected shackles hanging from the wall

On the shackles of the wall, there is also a dried corpse of a reaper with a lizard's head.

Judging by the various arrangements, it appears to be a prison cell.

"So, this underground space seems to be a prison?"

Li Xiaofei looked at a few other rooms.

The interior layout is much the same.

This space, located beneath the central temple, appears to be an underground prison.

It was supposed to be used to imprison the Reaper prisoners.

But after the cataclysm, it seemed to be a relatively safe place, so much so that the reapers in the city eventually had to retreat to their prisons to resist stubbornly.

But it is clear that they ultimately failed.

Li Xiaofei walked forward along the road.

Iron chains on both sides of the road hang braziers.

In the brazier, the flames danced.

It's an ever-open flame.

Immortal for 10,000 years.

The whistling wind stirred the tongues of fire.

The light in the corridor space is uncertain and jumps repeatedly.

With a burst of thunder and lightning.

The dead reapers, who had died in this area, were 'resurrected' again, turned into dried corpse monsters, and came towards Li Xiaofei to kill.

Then it was dealt with by the undead bone dragon Ao Ying.

After entering the underground prison, Ao Ying's combat effectiveness continued to increase.

He seemed to be absorbing the breath of death here, strengthening his body's energy.

He's very adaptable to this environment.

Li Xiaofei keenly felt that as he continued to go deeper into the prison, the stronger the 'resurrected' monsters around him became.

He speculated that it had nothing to do with the 'resurrection' itself.

It's because they're stronger before they die.

Gradually, the undead ancient dragon Ao Ying was a little unable to deal with it.

Li Xiaofei urged [Guardian Heart].

The streamer breaks through the sky.

One monster fell in an instant.

With his current strength, even if he encounters a tenth-order reaper, he can easily kill it in seconds, let alone these?

An hour later.

One man and one bone dragon came to the deepest part of the prison.

It's a huge underground space.

The dome is more than 40 meters high, and the width is at least about 3,000 meters.

The ground was littered with corpses.

In the end, the corpses simply stood, like the spring train of the Great Summer on Earth in the 80s, because it was too crowded, and even if you fell asleep, the scene would not fall.

And in the very center of the space, there is an underground magma pool with a diameter of a kilometer.

The magma boiled like boiling water.

It makes the originally gloomy space extremely hot.

There is something treacherous about the whole space illuminated by the harsh red.

In the center of the magma pool, there is a crimson boulder.

The top of the boulder is flattened and very smooth.

Sixteen black chains, extending from all sides of the lava pool, connect the boulder platforms.

On the rocky platform, there is an ancient altar.

The altar is divided into nine tiers.

The stone steps resemble red wax.

There are figures standing all around.

They are all rat-headed mages.

They hold the staff of the beast's ears in their hands.

All nine have been dead for a long time.

In such a scorching environment, the corpse's water evaporated and turned into a specimen-like dried corpse.

They maintain their pre-mortem movements, their hands raised in the air, as if they are chanting some kind of chanting.

At the top of the altar, a circular stone door.

The door frame is densely covered with various totemic symbols.

They are all depicted with the kind of white paint graffiti that Li Xiaofei is very familiar with.

In front of the stone gate, there was still a figure standing.

Three meters tall, crab head, human body, six arms.

This is clearly a high-level reaper.

In each of his palms, he held a weapon.

Or a staff, or a candlestick, or a rattan.

The shape is different.

On his head, he wore a metal crown like a crown with red gemstones, which looked luxurious and majestic.

But he's dead too.

Became a dry corpse.

Li Xiaofei stood on the back of the bone dragon, overlooking all this, and his scalp was a little numb.

This picture is as if at the moment when some important ritual is carried out at the most critical moment, and time is suddenly pressed the pause button.

Everything is dead here.

Like insects in a lake.

Thunder and lightning are already slowly forming in the air.

Li Xiaofei knew that a 'resurrection' was about to be born.

His body moved, and in an instant, he came to a huge rock platform in the middle of the magma pool.

The next moment.

Cracking sound.

The power of the thunder and lightning elemental spreads.

Countless reaper corpses were resurrected in an instant.

"I'll leave it to you."

Li Xiaofei stroked the head of the undead bone dragon Ao Ying.

The 30 million pieces of [Guardian Heart] shattered blades suddenly turned into dense scales, covering Ao Ying's body, turning it into a glowing metal dragon, and its combat power skyrocketed.

Ao Ying roared.

Immediately rushed into the crowd of corpses.

And Li Xiaofei came to the red wax-like ancient altar.

He was surprised to see that the altar was glowing red.

This light seemed to contain some kind of power, so that the dried corpses of the nine rat-headed mages standing around it were not resurrected by the power of thunder and lightning.

They remain dead.

Li Xiaofei remained absolutely vigilant and came to the top of the Red Wax Ancient Altar step by step.

The stone gate gave Li Xiaofei the feeling that it was like the interstellar portal in the science fiction movie "Stargate".

It's just that it's currently on the off stage.

The symbols on the door frame are completely unsolvable mysteries for Li Xiaofei.

He knew he couldn't solve it.

Even if these symbols may be addresses or coordinates, etc.

But it's all beyond his 'professional scope'.

Therefore, Li Xiaofei's gaze fell on the giant reaper crab head mage in front of the stone gate.

Affected by the glow of the Red Wax Ancient Altar, it was also not resurrected.

Li Xiaofei could see the expression on his face.

Panic and anger.

His eyes, in particular, still have God, as if they were alive.

He has a bag on his chest.

There are several books inside.

This made Li Xiaofei's eyes light up.

Finally found something written.
