The Life and Times of a Sentinel (Traditional Chinese: 紫禁驚雷) is a 2011 Hong Kong historical-fiction television drama produced by Television Broadcasts Limited (TVB), starring Steven Ma and Kenneth Ma as the main leads, with Leung Choi-yuen serving as the executive producer.

Set in the late 17th century, during the early years of the Kangxi Emperor's reign over Qing China, the drama stars Nip Dor-po (Steven Ma), a third-grade imperial bodyguard.

He is used by both the Kangxi Emperor (Power Chan) and Prince Yu (Kenneth Ma) to pit against each other, conflicting Dor-po's loyalty for both.

Angry with this, Fuk-tsuen dispatches a spy, Nip Dor-po, and instructs him to gain Hong-hei's trust.
