While investigating a series of murders, Interpol agent Jiang Lin accidentally falls into a church shrouded in Sanskrit. His left eye awakens the Nine Netherworld Eyes, and a black contract mark appears on his palm. He discovers that he is the sole survivor of the Jiuxiao Sword Sect, wiped out a thousand years ago, and that the serial murders in the modern world are quantum-entangled with the Yellow Springs Ferryman Array on the High-Martial Continent. The mandala tattoos on each victim's wrist are keys that open rifts in space and time.
