When Shen Xinglan grabs the bronze compass her father left behind amid the whirlpool off Devil’s Island, she has no idea she is about to uncover a secret that has lain beneath the waves for three thousand years. Her father vanished under mysterious circumstances seven years ago. Seven years later, she encounters a mysterious shipwreck in Tokyo Bay and accidentally triggers a deadly mechanism in an underwater tomb. Clutching the compass, the young woman is swept into a whirlpool in the netherworld sea. When she opens her eyes in the darkness, she discovers that the entire island is devouring the souls of the living.
The remnants of the Holy Trinity, descendants of Nanyang pirates, and tomb guardians who have slept for a thousand years clash in a bloody struggle on Devil’s Island. From a novice explorer hunted by all sides to someone who commands the tomb’s deadly mechanisms, Shen Xinglan must solve the ultimate riddle her father left behind within the three days of the nine stars aligning. Otherwise, an ancient evil god will awaken and engulf all of East Asia’s waters.
