Qin Mo woke up in a hospital bed, only to discover that his consciousness had long since left his body.
An anonymous suicide note and a crescent-moon heirloom led him to a secret buried deep in the bloodline of Qin Shi Huang: beneath the Earth's surface lay more than just layers of rock and magma. There were two entire eras, the mantle and the core. Ancient consciousnesses slept there, along with the laws that let the earth's veins channel energy, and the underground truth sealed away by the First Emperor.
As his spirit sank deeper and deeper, Qin Mo gradually saw a door to an underground era slowly opening for him amid the flames and whispers at the Earth's core.
