Academy’s Genius Swordmaster - Chapter 26: Banquet

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.

“There are no heroes. In life, the monsters win.”
