-Congratulations, you've reached Level 24-
After swinging his body around without stopping even for a second, Matthew had swung his claws hundreds of times, severing limbs, cutting necks, stabbing hearts, and strangling humans to death, Matthew had finally woken up from his battle frenzy when the system's notification told him that he got a level up.
He didn't know how many humans he had killed to get his level up since most of the humans' levels were far below him, but if he had to make a guess then it would certainly be around 100.
