Capítulo 63: The Monster Harvesting Monsters

Of course, there were people whose superbrain endorphin intoxication resulted in their mental strength index going overboard. Their courage and urge to kill increased by leaps and bounds. 

These people usually started howling when they saw monsters and eagerly engaged them in fights. 

Their mental strength indices could instantly reach 120%, 150%, or even higher. 

The increase in their mental strength index was definitely better than their mental strength index reaching zero, but there was a limit. A person's mental strength index was not allowed to go over 200%. 

If it stayed over the limit for too long, the brain cells would be completely immersed in the raging superbrain endorphins. The person would then turn into a bloodthirsty monster. They would not even be able to distinguish friend from foe and would just kill indiscriminately until they died from fatigue.
