I actually enjoyed that one despite the aseptized, blurred & heavily romanced Republican era / Warlords period background (none true to real History).
ML "Oliver" Chen XingXu played Shanghai Commander Tan XuanLin here and before that, Yang Kang in the 2017 best (to me) adaptation of Legend of the Condor Heroes. And young Zhang JingYi was a good FL.
The supporting team of "junior marshalls", cheeky sister and wide eyed actress were sometimes cartoon like, sometimes annoying. The villain war lords and their henchmen were suitably vicious and ugly.
Nevertheless, this drama had a surprisingly good plot with a not too heavy dose of sugar. Lots of twists & suspense.
Nice music, although I did not find it exceptional.
I don't plan to rewatch soon, but don't exclude watching some episodes again.
Small spoiler next - so don't read on if you have not watched the first episode.

Have no fear, our hero Tan Xuanlin was bound to walk almost unscathed through so many dangers because of the magic amulet his girl Miss Mu gave him once she began to sense that her kidnapper was not going to kill her (like he ruthlessly did in the case of a female spy in the beginning) 😁! Though everybody did not reach the end episode safely.
