Im A Max Level Regressor

as a member of the “nine road” for decades, i've traveled the world preventing global catastrophes. my long-awaited retirement was finally within reach. at 56 years old, what awaited me was the fame of being a battle-hardened veteran who had reached the highest ex rank, and countless accolades as humanity's hero and earth's guardian! all that was left was to truly enjoy a life of wealth and glory! and just as i was about to settle into a comfortable retirement… “aaaargh! this can't be happening!” i woke up to find myself as my 24-year-old self from 32 years ago! even worse, i'm back in the past when i had absolutely nothing!!! “i wasn't supposed to be the regressor!” moreover, nicholas from the nine road was meant to be the returner. does this mean i have to gather the nine road myself from scratch? a life forced to start over as an unexpected regressor! this time, i'll finish things quicker and try to enjoy life.
