When a bronze compass begins turning on its own at midnight and casts a star chart of the Burial Star Mountains, antique shop owner Lu Zhaoran and archaeology student Bai Xiaoyue are drawn into a secret of the mystical arts stretching back three thousand years. The bloodline of the tomb guardians awakens, the fissure to the netherworld begins to open, and behind seven ancient artifacts lies the brutal truth: the first tomb guardian sacrificed the remains of the stars. From the Nine-Star Altar to a war between two worlds, Lu Zhaoran chooses to enter the netherworld, while Bai Xiaoyue discovers that the so-called “seal” is actually a scam built on an endless cycle. The price of breaking the cycle may be civilization itself. This time, they decide to rewrite the rules.
