Tower of Truth, 40th Floor.

Mike appeared amidst swirling black mist, his eyes scanning the surroundings with caution.

"I wonder if I can get an SSSSS rating on this floor."

Based on his past experiences, every ten floors offered the chance to earn an SSSSS rating.

But now that the 40th floor had been taken over by the Supreme Demon God's forces, the storyline had started to unravel.

Mike recalled his previous SSSSS ratings.

The second was in the Frozen Wasteland, where he had encountered Dracula. 

The third was in Brookfield Town, where the White Wolf King had broken free from the cycle and entered the Temple of Truth...

Mike had analyzed the pattern before.
