Review Detail of FlyingCat_mei in The Return of the God Level Assassin [BL]

at first I did't understand the title. the 'assassin' part because will, one the Mc was not a assassin and two he was not reborn into a assassin family so idk what the part assassin was about. but after reading until the story take about the game then I got the idea that the assassin part was about that so ya, he was a assassin in a online game and it was a moon elf too! like author just add it in more Mc but not~(　´∀｀)b
