Listening to Yan Luo's introduction, Su Yuan felt very strange.

Olija steel is the hardest known metal ore and has a fairly high price.

The cost of making a maze with this stuff will be an astronomical amount!

No wonder only 18 floors have been built in 1,000 years!

Are the Tanaros family so rich?

Su Yuan was sure that the god Tanaros did not build this man-made labyrinth to play a simulated dungeon game.

In order to make more money, the Tanaros clan would sell special, intelligent monsters from the dungeons to the princes and nobles other than Eulari, which was strictly forbidden by the guild.

At the same time, Tanaros has also cultivated new types of monsters in the artificial labyrinth, apparently with special ideas.

Su Yuan wrote down this information first, and then said it when it was useful in the future.

……

After 8 days, when he came to the 37th floor again, Su Yuan looked at the huge skeleton monster from afar.

Udaios is extremely large, more than 10 meters above the ground, like an enlarged version of a skeleton.

In the chest of Udaios, there was a magic stone much larger than a human as the core, and the joints of the monster and the hollow eyes in the skull appeared with a faint red light, which looked strange and terrifying.

However, the monster of Udaios only has an upper body and cannot move, a bit like the original version of Susanoo.

It sits in the center of the entrance hall from the 36th floor of the dungeon to the 37th floor, and remains motionless and dormant as long as no adventurers approach.

Standing at the door of the hall, Su Yuan stared at Udaios and slowly drew his knife and unsheathed the "blast wind".

As if sensing Su Yuan's murderous aura, the huge Bone King turned his body and crushed the rock floor around him, making a loud rumbling sound in the hall.

The red eyes in its skull flashed suddenly, causing Su Yuan to take a step back behind him.

Sensing that the distance between himself and Su Yuan was beyond the range of the attack, Udaios suddenly slapped his hands on the ground.

Boom Boom!

With a loud roar of the earth, more than 30 "earth-borns" crawled out of the surrounding walls.

It was a skeletal warrior-like monster with no flesh on its body, only gray-white bones as hard as steel.

They hold knives, guns, swords, axes and other weapons that are also made of bone, and their strength is between lv3 and lv4.

After being hatched out of the wall, the earthly people swarmed up and rushed towards Su Yuan with a dense and terrifying attitude.

Without Su Yuan's order, the demons behind him put down their backpacks and took the initiative to rush towards the earthly creatures, blocking their steps.

Soldier against soldier, king against king.

But Su Yuan stopped them.

"Just look at it."

At the same time as the earthlings appeared, on the right hand side of Udaios, a huge black rock pillar stake rose from the ground, forming the shape of a giant sword.

With a length of up to 6 meters, this sword is an unimaginable heavy sword for ordinary people.

But in the hands of Udaios, it can only be regarded as a short blade.

Seeing Udaios grasp the big sword and start accumulating power, the dark purple magic power stacked layer by layer on its skeletal right arm, and the others showed shocked expressions.

"The Lone King of the Labyrinth still has a weapon?"

"I've never heard of it!"

Similarly, when Udaios was accumulating his strength, Su Yuan also had this idea.

"[Tempest Slash]!"

Woohoo!

In the spacious hall on the 37th floor of the dungeon, the originally calm wind began to flow at a rapid pace.

The massive amount of wind was absorbed by Su Yuan, causing the wind in the hall to howl, and the ultimatum wrapped around the gale, turning into a cyan air flow visible to the naked eye.

After charging each other's strength, Udaios slammed the short blade in his hand at Su Yuan.

For a moment, its right hand became blurred like a phantom.

In the roar of the atmosphere, under the suppression of the violent magic, Udaios took himself as the center of the circle and blasted out a fan-shaped shock wave!

The ground in front of it was crushed by an irresistible violence, shattering layer by layer, and even the bodies of many earth-living people were shattered by this magical storm.

At the same time, Su Yuan also waved the wind in his hand.

This first-class weapon, freshly crafted by the god Guberneo, showed its edge for the first time in this dungeon, emitting an extremely crisp and joyful sword sound.

Airplanes!

From the slender knife body, a ten-meter-long brilliant cyan sword light was like a dragon going out to sea, illuminating the entire hall!

The sword light carried an angry dragon-like wind around it, and in an instant, it suppressed the shockwave released by Udaios, and shattered all the earthcreatures with an invincible momentum, and swept back with the violent air current.

In the ferocious hurricane, even with the huge size of Udaios, he leaned back and swayed violently.

Immediately after, the cyan sword light exploded when it touched Udaios's massive head, and the blast of the air stream instantly smashed its head and shoulder.

The exploding blade light turned into a whistling tornado, enveloping Udaios with countless pale cyan blades, slicing through its steel-like body, making a creaking and screeching sound.

Tiny cracks appeared from the huge skeleton of Udaios, and then fell like a golden mountain and a jade pillar, emitting a huge roar, and then turning into flying ashes and scattering.

Yan Luo and the others saw that their eyes were straight.

"Killed Udaios, the equivalent of a lv6 adventurer, in seconds? Could it be that our new master turned out to be the legendary lv7? ”

That's a monster like no other in Olaria!

If they knew that they were going to deal with such a strong man, they would definitely not have done it!

Walking in front of this magic stone, which was taller than a person, Su Yuan felt a little pity.

The Rock Greatsword summoned by Udaios just now was also shattered by [Tempest Slash], otherwise it would have been a priceless rare drop item.

That night, Su Yuan asked them to bring this huge magic stone to the Adventurer's Guild to exchange it for money.

This magic stone alone was worth millions of faris, and even alarmed Ouranos.

However, they ran away after changing it for money, so even the staff on duty didn't know which clan did it, only that it was the group of adventurers who would only come out at night to exchange magic stones.

……

When they exchanged magic stones, Su Yuan went deep into the 37th layer.

According to Jan Luo, there are 5 large stone rings on the 37th floor, and each of them is a terrifying "infinite arena".

These stone rotundas will produce monsters that will fill the entire hall.

As soon as someone breaks into it, these monsters will attack like crazy.

What's even more amazing is that the number of monsters in the arena will always be balanced.

That is, no matter how many monsters an adventurer kills, how many monsters will crawl out of the stone wall of the ring, maintaining a certain number, almost endless.

So even the first-level adventurer group will avoid the arena and will not want to fall into the dense hordes of monsters.

This news can actually be learned from the corresponding adventurer advisor after the clan unlocks the lower level.

It was only in order to let the adventurers be cautious and rush directly to the lower level without going crazy, giving away their lives in vain, that the adventurers' guild publicly announced that it refused to provide information about the lower and deeper levels, and that each family member needed to explore it by himself.

But in Su Yuan's opinion, is there a more suitable place for him to farm monsters and upgrade than this "Infinite Arena"?
