Review Detail of sleepyeye in A Demon's Journey

strong guy takes possesion of a new and weak body a lot of time after his defeat, in other novels the mc just goes on their faceslapping journey, this guy intead bothers with information gathering and testing to make his knowledge up to date, and while gathering power in secret he needs to pay attention to not leave any track of his works because he is not yet the smartest or strongest in the continent. thats a pretty good thing for me
