Review Detail of king_of_Demons in Small upgrade system

review is only after readings 14 chapters . You can read it it's like humanity justice warrior story so you can read it if you like these Ideal plots . Like first of all he is like yeah they are 'my family'(like bro you didn't even know them before 2 days) and what if they get called to raid a SS tier dungeon for humanity so no I will use this system which basically gives me shortcut to power and become a savior of humanity in their stead , like his child like mentality is really pissed me off for good so yeah I am not reading it .like his parents are c grade like hell they are getting called for it ,we don't even know if he had parents before transmigration and if he does then he forgot them like asap and accepts new people as his parent in just a day and is even thinking of becoming their hero of justice ,knight in shining Armor and save them from unknown threat of ss grade dungeon and he knows his parents and his genius sister are only people in the world that will have to save humanity who are mere c grade people like what kind of manchild thinking is this .I know where this novel is going so I am leaving .
