Plot is a bit weak.
The exile was meh, the idiot hero as usual thought the MC skills were average or subpar and never realized he was the reason the team existed, same for MC not grading his ability correctly, when knowing the knew the party would got down without him.
"hero" as most times kicked the MC out of jealousy, a desire to build a harem and lies about the party members being fine with it, MC is in the bad too for blindly believing a bastard that just revealed their true character lies and not his actual friends that never showed any hostility and would have said something that important.
MC istantly unlocked a powerful skill when he got exiled, the requisite was high yes, but come the fucking on.
MC skills summons exactly who he needs a farming skill user, and is a slave, she gets freed, but still behaves like a servant and istantly fall in love and is full of trust.
MC got teleported to a death zone from someone that was friendly towards him, before getting any info or supplies, what a friend.
