Ke Mingye accidentally gained the ability to read identities and soon discovered that his family members were an extremely complex mix. Seemingly ordinary family members each had their own secret identities: —— “Superheroes,” “magical girls,” “ninjas,” “aliens,” “vampires,” “employee of Anomaly Control Bureau ,” “dragonkin,” “diviners”... Day and night, each family member tried their best to keep their secret identity hidden, so they made their days extraordinarily mysterious, behaving as normal as possible in front of anyone. But the identities they desperately concealed were nothing more than a string of data on the player panel to Ke Mingye. Just when Ke Mingye was lamenting that there wasn’t a single normal person in his family, he received a main quest from the game system... —— “Eradicate the Superhumans.” “Eradicate... the superhumans?” Sitting at the dining table, Ke Mingye was stunned for a long time, with his chopsticks in his mouth, as he turned his head to survey the room full of superhumans and thought to himself that this was pretty a “happy” surprise！XD
