The New Title

As soon as the 91st floor boss died, a void rift opened and a man in black and blue longcoat attire jumped out.

Huff!

Kahn panted loudly and descended on the dead Cthulhu's body while his entire countenance was that of an exhausted man.

"Phew! I'll still need a few days to recover." he said as big beads of sweat dropped from his forehead and chin.

Using Amaterasu to land that fatal strike at the expense of his soul essence had taken a huge toll on Kahn's body, mind and soul all at once.

Even after 3 hours, he was still in a weakened state and out of breath.

"System… How many?" he queried with a pained expression.

[All of the Host's physical stats have dropped by 15 levels while the soul is at 90% capacity.] reported the system.

"Ah, 15 levels and 10% of my soul essence sacrificed to kill one unkillable enemy…

I guess I have no right to complain." he spoke, letting out a contained sigh.
