Review Detail of zaijuro in Realm of Myths and Legends

a game novel taste xuan huan and pretty cliche. the author didn’t try to rationalize things on the novel like how the game console truly works; how it’s possible for the console to scan & measure the body condition & structure, how the AI works and its limitations, how the system can deduct an act as a potential skill & its mastery/power lvl, etc. and there’s one more that bugging me that the mc still need to “browser” the previous body holder memories, is he have a 2 brains or something?
