Forensic Heroes IV (法證先鋒IV) drama receives good rating record and will be airing the finale soon. During the promotion activity, the film producer, Mui Siu Ching (梅小青) expressed she will miss it and thanked the entire teams. When asked if there was any plans for the fifth instalment, she urged the audiences to watch the finale in order to know the answer. She also dismissed about the ending was to pave the road for fifth season as the script was written long ago and the cast team members were clueless about the ending.

Suggesting to invite Charmaine Sheh (佘詩曼) and Linda Chung (鍾嘉欣) to participate in the fifth instalment, Siu Ching chose to keep it a suspense and it was possible if commencing the shooting. She added both were her favourite actresses and her son was her biggest obstacle as he always sent photos of her grandchild, once thinking of filming the sequel.
