However, it was also during this search that a heavily guarded stone chamber was discovered—a palace-like interior with a towering vault and the rough style of ogres, but unusually clean, without a hint of rancid smell or creature bones.

"This really doesn't look like an ogre!"

"It's so weirdly clean!"

Ordering the soldiers to guard the perimeter of the stone chamber, the Rossi Paladin led Ron and Rost into the stone chamber - he immediately let out his feelings, after all, whether it is recorded in history or what Rossi Paladin saw with his own eyes, ogres are not clean-loving humanoids.

Archmage Rost, however, holds the opposite opinion – and his evidence is the frescoes on the stone chamber at this moment.

"Rosie, knight, you're wrong!"

"In antiquity, ogres also developed a brilliant civilization!"

"Look at these murals, they are already equivalent to the level of modern human painting, and they also record the history of ogres!"

Under Rost's guidance, Ron immediately saw the murals on the walls - the space in the stone chamber was huge, even an ogre was large enough to squeeze into hundreds of them - so there were quite a lot of murals on the walls, and the content was quite rich.

"Let's start here......"

"This depicts the stage in which the ogre is ruled by the one-eyed, a subspecies of the ogre......"

"Once an ogre gained arcane powers, overthrew the rule of the One-Eyed, then expanded, and established the Ogre Empire......"

As a few treasures, Rost begins to introduce Ron and Rossi Paladins to the history of ogres - in fact, there is also a small piece of such a ruin in Nimbala, and there is also such a stone chamber in it, but the stone chamber of Nimbala is not as well preserved as this one, and the frescoes are broken and not as rich.

However, that didn't stop Rost from digging into the legacy of the ogre civilization — a part of Nimbara's arcane origins from the ancient Ogre civilization — and has continued to expand on that basis — and now, Rost can be sure that the ruins on Elvon Island are the remains of an ancient Ogre civilization that are well preserved!

And in the corners of the stone chamber are some relatively large neat stone slabs - the ancient civilization of ogres has never invented portable text carriers - these stone slabs are their pages, on which the ancient characters of ogres are inscribed with content that no one can understand on the spot.

"It's a pity that I didn't catch that ogre wizard, and I don't know the entrance to the ruins!"

After introducing the history of the Ogre's ancient civilization to his two companions, Rost shook his head with some regret - although the stone chamber was discovered, it was only a record of the history of the ogre, and there was no record of the entrance to the ruins or the content of the magic.

In fact, ogres also burn their magic on stone tablets - except that such tablets are called rune tablets, and can only be found in the ogre's library, or in the laboratory of the ogre archwizard - Nimbala's ogre ruins have a small library with dozens of rune tablets, from which some of Nimbara's spells are born.

And when Archmage Rost sighed, a slight moonlight rat chirped suddenly from outside the door of the stone chamber - Ron turned his head to look and saw Fagle's fat figure swaying by the messy pile of rocks outside the stone - obviously accustomed to the dirty and messy environment of the ogre walled city, and the soldiers guarding the door did not feel any different from the moonlight mouse in front of him - except that it was too fat.

"Lord Rost, Lord Rossi, I'll go out for a while!"

"My degraded species may have brought some news!"

............

"Lord Ron, is this the entrance to the ruins?"

"Yes, Fagger said he watched the ogre wizard disappear here!"

"Look, where he is!"

Fagle did make some discoveries - and then he led the three of Ron into the innermost part of the stone chamber - Archmage Rost apparently didn't realize that there was a secret door in the stone chamber that recorded the history of ogres.

However, after Fagger made a gesture of jumping in front of a mural, Archmage Rost stretched out his staff and struck the wall with a crisp sound.

"It's empty inside!"

"Get out of the way, everybody!"

"Percussion!"

Motioning for everyone to step back, Archmage Rost cast a spell, and immediately the eyes of the first ogre king Gogel depicted on the mural slowly lit up, and then moved a wide tunnel behind him that contained the ogre's passage - the tunnel was not deep, and inside was a rotating arcane vortex - in the center of the vortex, a brilliant emerald with a keyhole in the center was suspended.

"Found it, Alpha Mystery Lock!"

Archmage Rosst immediately recognized the name of the portal - although it was strange that a door was called the Alpha Mystery Lock - but at the behest of Archmage Ross, the Paladin Rossi immediately walked out of the stone chamber and gathered a team of elite centaurs to come to the Alpha Mystery Lock.

And before asking Ron to open the mystery lock, Archmage Rost solemnly summoned everyone together.

"The Alpha Mystery Lock is a magical door lock, and once you step into it, you don't know what kind of situation you will encounter!"

"It's possible to become other creatures, it's possible to go back in time - but remember that it's all an illusion, and make sure you survive!"

"As long as you survive for a certain amount of time, you will automatically teleport to the world behind the mystery lock!"

"However, if you die in the mystery lock, then you are really dead!"

"Remember?"

After telling the people about what he knew, Rost turned his head to Ron - in fact, there was something that Rost didn't know, that is, the Alpha Mystery Lock was also used as a learning tool for ogres - because the intelligence of ordinary ogres was too limited, so the ancient ogre sages developed this system of body memory.

Since the brain can't remember, let the body remember it - if you can't even remember the body, you can die!

............

"Lord Ron, please use the key of the Alpha Mystery Lock to open this door!"

At Rost's request, Ron slowly floated up, inserted his long, rusty key into the keyhole in the middle of the emerald, and twisted it vigorously!

"Click!"

With a crisp sound, the emerald suddenly emitted a faint green light, and then retreated into the vortex - and then under the leadership of Archmage Lord, the entire team disappeared into the swirling blue and white portals one by one!
