Two thousand years ago, the Emperor slayed a dragon in the wild, inaugurating the era of mankind.Since then, whenever malevolent dragons wreaked havoc, heroes have always emerged as destined, allowing time to flow across a long and peaceful human world.As the century turned, the sudden appearance of individuals with supernatural abilities triggered unprecedented disturbances. People constructed a sanctuary for these superhumans in the sky, on the back of a colossal dragon, called the Dome City.One spring day, Gongsun Ce, who had just started university six months ago, encountered a hunter who claimed to be a Wuchang master.“Hey, can you really do such a thing?!”“It's quite normal, because I am a superhuman.”—Thus, the love-comedy battle of supernatural abilities in a youthful campus begins!

Xu Niannian was reborn in the 1980s and became the most beautiful flower in ten miles around.With three younger brothers at home, her sharp-tongued mother loved her as her life; daughters were golden lumps while sons were just a waste of money.She had thought she would encounter a host of troublemakers, but although there were many, they ended up spoiling her rotten.The stingy grandmother, upon meeting her, would always dig out the best things for her.The acerbic mother, who was scolding her sons just a second ago, would instantly change her expression to a blooming chrysanthemum upon seeing her daughter.Thus, Xu Niannian's goal became to work hard to earn money and keep her quirky family well-fed and chubby.Having obtained the Spiritual Spring by chance, Xu Niannian grew more beautiful every day.When Jin Yu first met Xu Niannian, he only felt that the girl was charming and bewitching, beautiful enough to dazzle him.He had another girl in mind, yet was inexplicably captivated by Xu Niannian's allure, unaware that the one he wished to take responsibility for and the one he liked were the same person.
