Rebirth of a Life Beyond Limits

Traveling to an unknown world, Wu Ming felt familiar, the Hero Association? Isn't this a one-punch world? It's over, how can I survive as a gangster? The system starts, and the master is asked to complete the task and gain the power to survive. Saitama doesn't exist? Not those familiar characters in the Hero Association? So what is this world?
