@xeno77 lmao.
This is basically the same as a bunch of other manga that have a complete ripoff (so far, through chapter 7) of the manga "
I Was Kicked out of the Hero’s Party Because I Wasn’t a True Companion so I Decided to Have a Slow Life at the Frontier".
Basically, the party thinks that he's dead weight so they kick him, then almost immediately run into some trouble because he was secretly holding the whole party together with his efforts that they didn't notice.
Basically, seems like revenge-porn for the salaryman who got fired recently. The manga that it ripped off is actually pretty good, although I'm not sure if that one or this other series called "
I Was Dismissed from the Hero’s Party Because They Don't Need My Training Skills, so I Strengthened My [Fief] Which I Got as a Replacement for My Retirement Money" came first. The one that it (probably) ripped off has a very similar setup, but the Training Skills one seems more like a guy who gave a company/startup all he could, and they didn't really need him anymore, which he's made peace with, so he goes and starts his own business (figuratively). Rather than being about actual direct revenge or revenge-porn it's more like living well is the best revenge? I just said revenge a lot lmao.
Personally the other two are better than this one so far, although this one could get better, it's not like some of the edgy ones where the hero got betrayed and is trying to burn the kingdom to the ground or something. Those I feel like you have to be in a certain, vindictive, mood for.
