Just as Minos' group was ready to go ahead with their last fight in that underground building, he raised his own cultivation and that of five aliens.
By strengthening two of his guildmates and three of his group's allies, Minos advanced alongside those five individuals into the large area at the deepest point of that building.
Upon entering what looked like a huge crypt, the group was immediately attacked by the brown creature there.
The creature there formed several snake-like body parts. It used them to attack the vital organs of the six individuals who had first invaded its home.
But simultaneously with its merciless attack, the three individuals with special artifacts used their belongings, making the special powers of those devices show their differences in battle.
Even though they were only Grandmasters and that one was a mid-level Sovereign, the three aliens immediately managed to counterbalance their opponent's powers.
