Regeneration
The total numbers of bats remaining alive were just 5, after fighting Kang-Ho for quite a while it didn’t seem like the bats were a match for Kang-Ho. Bat’s corpses were littered on the floor, the corpsed of the bats covered the entire floor, not just the corpses even the blood covered the floor. The stench that came from the room was just unbearable for any normal human, but for Kang-Ho the stench didn’t matter that much as he was not bothered by the smell in the slightest, there was something more concerning for Kang-Ho than the stench itself.
