- Description from novelupdates

The way of a Demon Lord - since the beginning of time, countless demons dreamt of it but few dared to tread on it, and even fewer reached its end. But the rarest of them all were some special demons who were not allowed to step on it, because if they were to become a Demon Lord- even the other lords would have to bow their heads. Abhorred and hunted by all, they could not do anything but hide till their lifespans came to an end. But for the first time ever, one such demon chose to do otherwise.

Follow Adrian Darkheart as he uses his special demonic power, superior intellect and innate brutality to walk the path of chaos and destruction and become the greatest Demon Lord ever.

When the system warned the world that it was coming a week in advance, Alex couldn’t have been more excited. In college for a degree he didn’t care about to get a job he didn’t want, the promise of a world where magic and challenge awaited — even at the potential cost of death — was the best news he possibly could have imagined. Alex was ready for a new life. He ready for his only friend to shove him through a portal into hell the moment the apocalypse started. Instead of getting to punt rabbits and farm wolves, Alex finds himself stranded in a warped world where even the bugs are stronger than he is. Even with a summoner class that gains the powers of its monsters, most people would have died. Alex didn’t get the memo. He might have liked challenge a little bit too much. Where others saw certain death, he found something else. Opportunity.
