In the heart of Manhattan's Chinatown, one young doctor carries a secret that could change his fate?and everyone else's.

Ron Ding is more than a gifted practitioner of traditional Chinese medicine. He has inherited a hidden system that allows him to do what no other healer can: draw treasure, fortune, lifespan, or opportunity from every patient he treats. Each pulse he reads is a doorway to power. Each prescription carries a price beyond money.

From priceless antiques to fragments of immortality, Ron's choices pull him deeper into a world where medicine and magic blur, where Chinatown's elders hide dangerous secrets, and where even the most ordinary encounter may reveal a treasure?or a threat.

Blending the rich heritage of Daoist arts with the pulse of modern New York, The Crimson Oath is a sweeping urban cultivation fantasy filled with hidden treasures, ancient techniques, and a healer who charges more than money for his cures.
