There are countless complex passages in the huge cave, and the black fog in the cave has been dispersed, but there are still countless dense black fog gathered in the passages, so Irina can only release a holy light shroud to envelop everyone throughout the whole process, usually relying on her perception of the source of the black fog to continue to deepen.

The speed of the crowd was very fast, and after about a quarter of an hour, Irina stopped, and the holy light shield shattered, shaking away the black mist in the passage, revealing the huge stone door at the end of the passage.

The black stone gate is 100 meters high, and it seems to be carved with a huge mural on it.

Crassus let three fireballs fly close to the stone gate, and everyone could see the picture carved on the stone gate.

"This!"

Everyone was shocked.

The huge mural depicts a terrifying scene, with dragons biting and killing each other; The forest troll twisted off his companion's head, still biting half of the elf in his mouth; Scarlet-eyed goblins ride orcs and chase a frenzy of monkeys; The endless sea was stained red with blood, and the corpses of dense demons floated on the surface of the sea, being frantically bitten and eaten by a group of terrifying-looking fish......

And in the center of the whole mural there was an indescribable object as huge as a hill, and the dragon was as small as a mosquito in front of it, and countless tentacles poked out from under the hexagonal seal that was suppressed above its head, and those tentacles were covered with scarlet eyes, flashing with a strange light, as if it was about to break through the seal.

"What kind of monster is this?!" Crassus was also taken aback and exclaimed.

"There is such a disgusting existence in this world, evil, it must be used to describe it." Irina also looked away a little disgusted.

"This scene is familiar, when we entered Cannibal Island, the scene we saw was somewhat similar to this." Julian's eyes narrowed, and his hoarse voice raised a little.

"This is supposed to be the Old Dominator, or rather the Devil, somewhat similar to the stone statue that the Unreleased Found in the Eba Clan." McGonagall looked at the huge mural with a solemn expression, and the scene in the picture was very similar to what Rex had originally described.

If the stone statue may be the work of the imagination of those believers, then this huge mural handed down from ancient times must be a warning left by the sealers to future generations.

"It is not necessarily death that sleeps forever."

McGonagall saw in the corner of the mural the classic phrase that he had seen in many books during this time, perhaps some kind of coincidence, or some kind of necessity?

"So, he's locked up here now, isn't he?" Crassus tightened his grip on the mage's staff, his expression becoming a little solemn.

"Come on, let's meet this big guy!" Irina said eagerly.

"Aren't you afraid? I remember what you were most afraid of with long tentacles? Julian asked, looking back at Irina.

"What's the use of being afraid, if even the four of us join forces and can't deal with a guy who is bound by a seal, this world will be over, right?" Irina asked rhetorically with a smile.

"No, we still have precious things to protect." McGonagall held her sword and walked towards the gate first, and the knight was naturally in the front row when fighting, and there was no reason to hide behind the mage.

The majestic gate seems to have been specially designed for giants.

Julian closed his eyes facing the giant gate, and wisps of frost quickly covered the giant door,

After about a minute, Julian opened his eyes and raised his hand to fly out several ice balls, each of which smashed into the extra spot on the stone door.

With a dull creak, the massive door began to move slowly backwards.

"Be careful!" Irina reminded, raising her hand to place a blessing of light on everyone.

As the giant door opened, a thick black mist began to rush out from the crack in the door, accompanied by some kind of dull whisper, like a demon from the abyss.

The black mist crashed into everyone's blessings of holy light and scattered, and McGonagall slowly walked into the world behind the door with her sword in both hands.

The brilliant light annihilated the black fog and pierced the darkness.

Behind the giant gate is an empty cave hundreds of meters high, and on an altar inscribed with countless ancient runes, countless black chains are intertwined and tied to a behemoth like a small mountain!

The four of them looked up at this scene, and their eyes showed a little surprise.

It was an incomparably large octopus, and countless tentacles poked out from under him, and above that tentacles were full of eyes, each of which glowed with a strange red light.

A six-pointed star seal pressed above its head, flickering with a faint pale golden light, as if it would be annihilated at any moment.

"Boom—"

The octopus monster also seemed to hear the sound of the door opening, and let out an eerie growl.

McGonagall felt that she was suddenly stared at by a myriad of pairs of eyes, and those dense eyes seemed to be all looking at them, and tentacles suddenly stretched out, rushing towards the doorway.

It must be a nightmare for people with dense fears.

Magethia's sword prepares for battle.

Crassus and Julian also held the mage staff and magic wand, respectively.

But just as the tentacles were about to reach McGonagall, a pale golden curtain wall suddenly rose around the altar.

The tentacles slammed into the golden curtain wall, as if hitting a wall of fire, making a sizzling sound of corrosion, and the tentacles began to melt at a speed visible to the naked eye.

The behemoth let out a scream, and the countless tentacles suddenly retracted.

"The seal design is quite reasonable." Irina smiled and withdrew the mage staff, walked around the altar, and wondered, "Is this the guy's head?" ”

"It should be, just a head is so huge, and the size of his body can be imagined." McGonagall put away her sword as well, frowning at the octopus.

The tentacles are covered in brownish-green mucus, and the wriggling tentacles are disgusting.

"Is it burned with fire? Or is it frozen? Crassus asked, touching his chin.

Julian walked around the entire altar, and said with a solemn expression: "Conventional magic is ineffective against black mist, and I don't expect to have much effect by directly casting it on his body, his state is not very active, which means that this sealing formation is still effective, and the safer way is to seal it again on the basis of this formation." This guy has an incomparably terrifying magic in his body, and once unleashed, we are no match for it. ”

Crassus frowned and stared at the octopus monster for a while, then nodded, "Okay, I'll listen to you this time." ”

"What do you think?" Irina turned to look at McGonagall.

McGonagall couldn't agree with Julian's statement, this was just a head of the Old Dominator that had been cut and sealed for countless years, but standing in front of it, there was still a sense of insignificance in the face of eternity.

He had to admit that even if the four of them joined forces, they still didn't have any confidence in fighting this guy after breaking free from the seal.

However, he has a task ahead of him!

The re-sealing is just a delaying tactic, and if we can't find a solution to these old rulers, they will one day still get out of trouble and harm the world.

"I'd like to slash it and try it." McGonagall said seriously.
