Lu Ming, a delivery boy who shuttles through the reinforced concrete jungle, races against time and struggles with life day after day. He once thought that life was so ordinary, until that rainy night, a mysterious APP called "Tianji Compass" appeared on his phone out of thin air. It can not only guide the best route and predict the weather, but also have insight into people's destiny and pry into the secrets under the city's undercurrent.
From being dubious at the beginning to becoming more familiar with it later, Lu Ming's life trajectory began to undergo earth-shaking changes. He is no longer just a food delivery boy, but a "guide" who walks on the edge of light and darkness in the city. Behind the seemingly ordinary orders, there are hidden bizarre events, lost treasures, souls waiting for redemption, and even plots ready to start.
With the guidance of the compass, he resolves crises, helps others, accumulates merit, and unlocks more mysterious functions of the compass. When he stood higher and saw farther, he discovered that beneath the surface of this bustling city was a chess game intertwined with ancient heritage and modern technology. And he, the delivery boy Lu Ming, was actually a vital piece in this chess game. With his identity counterattacked, how will he use a mobile phone and a compass to rewrite his own destiny and even control the future of the entire city?
