Review Detail of Jade_beauty_tits in Tinkering With Life (GoT SI)

There are some reviews saying that the MC has no ambition and they give a low score, this is false because the MC does have ambition, not in gold or land but in knowledge, he studies the limits of his ability that can make him immortal so that if worry about being a lord? this is the good thing, but in chapters 15 onwards the MC starts to turn psychopath which I don't like and will probably make me drop, but who likes that I recommend it
