Clearing the third floor was not further difficult. It was pretty easy to find a way down toward the fourth basement. Liam didn't even have to spend ten minutes before he got down to the fourth basement to take a look at the situation.
What he saw in the fourth basement was enough to understand one thing for sure; the fourth floor was the final floor.
The underground tower had only four basements from the looks of it. As for the lowest basement, it was protected by a large number of Shedim and the Boss Monster. Boss Monsters were existences whose strength had been artificially enhanced by providing them with a tremendous amount of Arcane Power and various other means.
If the Boss Monster would have been an Ordinary Shedim, its strength would be elevated to rival that of Mutant Elite Shedim. That was how terrific the potency of a Boss Monster's amplification truly was.
