Not that bad I'll be honest, though mc get rewards from impregnating woman, but mc's father got more plot armor than himself like every resources naturally found in their world is always fit for his father and mc's father luck also insane.
Trash mc always let go of the enemy and wait for them to seek revenge for the fucking million times before he killed them instead of cutting them off and finish those shitty people coming and going they just some shittty additives they use to make same shitty plot
Mc is overpowering with 250+IQ(according to novel) yet he is pushover who would sacrifice his zerg for human that betray him multiple times and his strategy all the time was to destroy his zerg for the benefits of others that hate him. And author also like to make the villain slip out from predicament so that he could reuse them over and over. Which making the mc unreliable and trash for being idiot ironically to how they introduce him
