A cool and restrained contemporary fantasy. A Linjiang deliveryman signed a contract passed down from his ancestors and became the "Mountain and Sea Pulse Keeper" hidden under the contemporary market - he had to guard the underground vein, and he had to keep his mother who disappeared nineteen years ago. Delivering orders on a rainy night, there was something lying on the cross arm of the tower crane that shouldn't exist - he "opened his eyes" and saw the gods of mountains and seas wandering in the city.
His mother, Lin Yan, disappeared nineteen years ago and left him a "book of mountains and seas" and a "price of name." Following the guidance of the book and Su Wan, the neighbor's pulse keeper, Lin Mo ran into a secret world that his mother had guarded all his life: Yinglong was trapped in a cave at the construction site, Xiang Liu lived in the rental house next door, Bai Jin guarded an old bookstore that only accommodated "people who are too lonely", and Bai Ze guarded a thirty-one-year contract.
