Medusa seemed not interested in the three of them. After opening the entrance to the seventh-story underground palace, she no longer cared about whether the three of them were leaving or staying.

Instead, he sat alone on the stool next to him and read a scroll of parchment.

When Bai Yu saw this scene, he felt extremely strange. He should be the guardian of the entrance, but this attitude was too perfunctory, and he always looked like a guardian.

I thought there would be another big battle.

It turned out to be like a punch hitting the cotton.

Just as the three of them were about to enter the underground palace, people's footsteps suddenly sounded outside the stone palace, and a group of small warriors seemed to have also explored here.

However, they did not enter rashly, and stood from a distance and looked at the stone palace, obviously very cautious.

After watching for a while.

Then they slowly stepped into the corridor in front of the palace.

But after stepping onto the corridor, the people's bodies suddenly turned into petrified and immediately turned into several stone sculptures standing there, with no breath of life.

Medusa was still looking down at the book.

Bai Yu finally understood why the other party was so calm. Obviously, this was a detection mechanism. If the strength was enough to step into the palace, Medusa would naturally not launch an attack.

If the strength is not enough to enter the palace.

The corridor outside the palace would be petrified and would not be able to contact Medusa at all.

That's why she is so leisurely here.

"Let's go."

Machimado glanced at Medusa, without continuing to speak, and took the lead in walking into the interior of the underground palace.

Bai Yu and Cai followed closely behind.

After the three of them entered, a large number of mechanical undead stepped in in a uniform pace, just like the most disciplined army in the world.

...

There is almost no light source under the underground palace.

Cai took out a ball of light from his body and illuminated the dark authenticity.

The three of them were in the middle of the mechanical undead team, and the speed of progress was smooth.

Soon the first underground palace appeared before them.

It's not just an underground palace.

It's better to say it's a real underground world.

Although I don’t know how Qipan entered here, the area inside can definitely accommodate a giant like Qipan.

According to the area of ​​this underground palace.

The entire sky garden is obviously hollowed out inside and is made into a seven-story underground palace, which is somewhat similar to the Zen City.

But its area.

It is much wider than the Zen City.

The entire underground palace was quiet. The houses built in ancient times still could not stand, but half of the creature could not be seen.

"The first underground palace is called the Challenge Underground Palace. Did you see the huge arena in the middle? It is a place where Qipan used to punish criminals and please themselves and their believers.

Although Qipan is the Shishi God.

But his wild and cruel character made him very fond of bloody battles as sacrifices.”

Machima pointed to the terrifyingly large circular building in the middle.

Look from afar.

The building is almost the size of a ten gymnasium, and it is estimated that it can accommodate hundreds of thousands of people at the same time.

Machima's goal is this ancient gladiatorial building.

However, in addition to the huge arena on the first floor of the underground palace, although there are buildings in other places, most of the interiors are already ruined. There are really good things, and they must be in the huge arena in the middle.

The three walked all the way to the arena.

Only then did I find that there was a huge ball of light floating above the arena, providing a light source for the dark arena.

The light ball gives Bai Yu a sense of familiarity.

It reminded him of the intelligent light ball on the arena in the fierce battle in the yellow sand world.

The three of them stepped into the arena.

The huge flat ground in the middle is covered with neatly arranged floor tiles, and a circular auditorium is surrounded by a high platform.

A faint smell of blood came.

On the walls between the arena and the audience, clusters of bright flames hung after clusters, making crackling sounds when burning, providing light and heat to the arena.

Instead of stepping into the arena at the first time, the three of them sat in the audience.

In the center of the arena.

Two corpses were lying on the ground and were dragged out of the arena by two stone men, leaving two long blood marks on the ground.

Until they disappear into the iron fence of the wall next to the arena.

"That seems to be from the three major families, and it seems to be the one in the direct line." Bai Yu frowned. Although the light was not very sufficient just now, the clothing of the three major families was very obvious and could be seen at once.

Machima nodded: "It seems that this arena is still operating."

The two died in a fight.

This is obviously extremely strange in the empty arena.

"Is it true that you have to step into the arena before you can change?" At this time, Cai made a bold guess.

She is the type of doing it just by saying it.

Since there was this conjecture, she immediately sent a mechanical undead to the scene. These guys would be reborn in the mechanical cabin if they died. Even if they entered the arena and were killed instantly, it wouldn't matter.

However.

A mechanical necromancer stood in the arena, but there was no reaction at all.

Cai had no choice but to call the mechanical undead back, jumped and jumped down.

This time.

The flames around the arena expanded rapidly and rose. Neither Machima nor Bai Yu in the audience could enter the arena again.

"Challenger, if you want to gain the recognition of the Seven Gods, you can pass your test."

At this time.

The light ball floating on the arena suddenly made a sound.

Unlike the ups and downs of the female voice from the light ball in the fierce battle, this is a neutral voice that cannot distinguish between men and women.

After the sound fell.

A beam of light suddenly appeared opposite Cai, and among the beam of light, a burly figure gradually condensed.

The other party is about two meters high.

Humanoid.

He was wearing painted black armor with barbed armor, holding a giant sword in his hand, his eyes and skin were dark blue.

Devil clan!

Seeing the magic horns on him and the special skin color, Bai Yu instantly recognized the other party's identity.

"The devil tribes will also appear here?"

Bai Yu looked at Machima.

The other party said in a deep voice: "The Devil Clan already existed in ancient times, and it was also a super clan. During the Frost Empire, the Devil Clan members were killed on a large scale, which led to their current scale not posing a threat to humans.

This devil clan member.

It is very likely that it was sealed by a special method by the arena, which left behind from ancient times, so its combat power is much stronger than that of the ordinary hexagonal devil clan."

When Machima introduced to Bai Yu.

In the arena.

Cai has already fought with this devil warrior.

The opponent's giant sword opened and closed, and the dark armor was all over his body, which could actually block the laser light emitted by the color.

For a moment.

Cai was suppressed by the great sword and retreated step by step.

However, seeing that the rhythm of the battlefield was still not chaotic, although Cai was defending, he was at ease. Obviously, it was not difficult to deal with the warriors of the devil clan.

really.
