It wasn't long before the person they had saved died. Or perhaps it's more accurate to say, they never had the ability to save him in the first place, and even if they did, they wouldn't. After adventuring for so many years, everyone was no longer the novices they once were.
Du You was already in his third year of college, and he had spent an indeterminable number of years in the Other World.
After the man had truly died, Du You waved his hand and released a cluster of black flames that completely incinerated the body. This was his passive skill, Soul Devouring Demon Flame, which he could now also summon at will.
Maybe it's ineffective in combat, but when used directly for starting a fire, it posed no problem.
"So, what should we do with this thing next?" Du You muttered to himself.
