The Crimson Dust Sacrifice

Hong Zi, an ordinary office worker, has avoided starting a new relationship ever since her first love, Luo Chen, died in an accidental gas explosion several years ago.

By what seemed like a chance encounter, she met Xu Yuan, an agent working undercover. Xu Yuan was investigating the case of Hong Zi's first love, Luo Chen, from several years ago. He laid out the evidence that made him suspect the incident had been murder, not an accident, and asked Hong Zi to help with the investigation.

Determined to clear her first love's name, Hong Zi joined forces with Xu Yuan and began a quest to overturn the verdict in the gas explosion case.
