The trio stared at McGonagall in deep thought.

McGonagall looked at them and fell into deep thought.

He really didn't want to pretend to be forced, he ...... It's a last resort.

"I'll cut it." McGonagall tried.

"Okay, it's a gentleman, I'll accompany you to cut him." Crassus patted his chest and said.

"I can slow him down." Julian nodded slightly.

"I can use the Holy Light to open a path for you within the seal, but the concentration of the black mist there cannot be estimated, so this time may be short, and you must return as soon as you finish cutting." Irina smiled.

"Okay." McGonagall nodded, stood in front of the altar with her sword in both hands, and exhaled lightly, her expression becoming extremely solemn.

"It's coming!" Irina snorted softly, and a brilliant holy light shot out from the mage's staff, instantly illuminating the cave, and a passage was carved between the thick black mist, rushing straight towards the center of the octopus monster's eyebrows, leaving a black scorch mark several meters deep in the center of its eyebrows, and still failed to cause substantial damage to it.

Almost at the same time, Julian slammed the mage staff to the ground, the temperature in the cave dropped by dozens of degrees, and the frost began to spread rapidly towards the octopus monster from under his feet, and soon, a layer of white frost condensed on the tentacles of the octopus monster, and the speed of squirming was visibly reduced, and the movement was obviously slowed down and limited.

"Hey! Taste my big fireball! Julian let out a loud shout and jumped dozens of meters high, and the mage staff swung towards the octopus monster, and huge red fireballs flew towards the octopus monster like meteorites.

"Boom—"

The octopus monster seemed to be enraged by the crowd's actions, and let out a low roar, flicking its tentacles and scattering most of the fireballs, but a few fireballs still landed on its tentacles, and the explosion of fireballs left a scorched black mark on his body, but the injuries were quickly repaired.

"It's now!"

The moment Irina's light was activated, McGonagall had already chased the light into the seal, her sword rising and slashing down at the nearest tentacle.

The Tiandu Sword is not a very sharp sword, but it is a very hard sword, and with his sword skills and strength, it is almost invincible.

But this sword stood on top of the tentacles, but it seemed to be cut in a swamp, the sticky and soft touch removed most of the strength of the long sword, and the countless suction cups above the tentacles went up with the trend, sucking the Tiandu sword deadly, making it difficult for him to withdraw the long sword.

A pair of scarlet eyes were already fixed on McGonagall, like a beast staring at its prey.

More tentacles were pouring in his direction, proving that the octopus monster had noticed him as an intruder.

The blow was unsuccessful, and the sword stuck to the tentacle again, and probably nothing worse than that.

At the moment, McGonagall had only one choice, abandon the sword and leave, Irina and they should be able to leave him a way back.

McGonagall glanced at the Tiandu Sword in her hand, the hilt of which shimmered, as if she wanted to say something.

In the midst of the lightning, McGonagall suddenly pulled the fathead fish from her waist and stabbed it on top of the tentacles.

"Da!"

With a crisp sound, the tentacles as thick as a human waist were actually broken in response.

"It's done!?" McGonagall's eyes lit up, and she couldn't care about being stunned, she backhanded the fathead fish back into the scabbard at her waist, carried the Tiandu sword with the octopus tentacles on her shoulder, and turned around and ran away.

The passage left by the holy light was getting smaller and smaller, and the black mist on both sides was squeezing wildly, and behind him, countless tentacles were rushing in.

"Bang!"

McGonagall almost knocked out of the seal and reached out against the stone wall, leaving a half-foot-deep palm print.

Behind him, countless tentacles crashed into the golden wall of light, and with a flicker of the wall of light, the colliding tentacles melted one after another, and the octopus monster let out an angry roar.

"It's worthy of Alex, such courage and courage, the younger generation, I can't find a second person." Crassus looked at McGonagall with an appreciative expression.

"Only when we are infinitely close to death can we understand the true meaning of existence." McGonagall wiped a cold sweat and said as calmly as she could.

"I didn't expect this devil's tentacles to really be able to cut off." Julian looked at the tentacle that was still attached to McGonagall's longsword with a surprised expression.

After leaving the seal, the tentacles shrank by half, but they were still as thick as human thighs, just a tentacle more than a meter long, and there were eight eyeballs on it, and the red light had disappeared after being cut off, but it still looked very weird and terrifying.

"This monster should have a very strong self-healing ability, and the broken tentacles can be fully restored within three breaths, so it doesn't matter if it breaks a little tentacle." Irina looked at the octopus monster that had recovered all its tentacles, including the injuries caused by Crassus earlier.

"The damage caused by holy light magic is indeed stronger than that of ordinary magic, and it is not so easy to repair." Julian looked thoughtfully at the wound on the octopus monster's brow, which still existed.

"In that seal, I can feel the strength of this guy more clearly, its body contains unimaginable energy, and it also has extremely powerful spiritual power." McGonagall said as the only person to have ever entered the seal.

"It seems that for now, we can only strengthen this seal, so that it will not be able to get out of trouble for the time being and attract its followers to come here, and then slowly find a way." Julian frowned and began to study the ancient runes around the altar.

"If you need materials, I have some here, you can see if you can use them." Crassus threw a storage ring to Julian.

"I also have a batch of formation materials here." Irina waved her staff and there was a bunch of glowing materials in front of her.

McGonagall took advantage of everyone's lack of attention, quietly pulled out the Tiandu Sword from the tentacles, and then took the fathead fish and cut off an octopus whisker with eyes, and said in her heart: "System, hurry up and receive this fresh tentacle of the old ruler!" ”

"Ding! An unknown powerful creature ingredient has been detected! Checked! ”

"Congratulations to the host for completing the high-level quest and obtaining a copy of the Old Dominator's ingredients!"

"The test report will be sent to the host after 24 hours, please pay attention to check it at that time!"

The octopus whiskers in McGonagall's hand vanished, and the sound of the system sounded in her head at the same time.

It wasn't known what the system would be able to detect, but it was probably one thing they could expect at the moment, and perhaps they would be able to get a way to contain the octopus monster from the inspection report.

The terrifying thing about the Old Dominators is not how powerful their physical bodies are, but their ability to influence and manipulate the spirits of creatures everywhere, even if they are sealed thousands of meters deep underground, shrouded in heavy formations, they are still influencing this world.
