In the Dragon Soaring Continent, a world where only summoning exists, without magic or fighting spirit, a man named Yue Yang transmigrates and discovers he has become the third young master of the Yue family, a drowned ghost who committed suicide after being jilted by his lover. The original third young master was considered the most useless of the four great families, failing to contract a summoning grimoire for fifteen years. Yue Yang, however, only needs one day. When others struggle to contract spirit beasts, countless divine beasts and sacred beasts flock to him.
