Decided to watch this series as it can been compared to The Untamed and been regarded as China's second best option for BL content after The Untamed. The series started off strong. It was interesting. However, it is not a BL at all though. More like a Bromance. Unfortunately, it became slow, overlong and dull. So after watching Episode 10, I decided to drop it or at least put it on hold. Maybe, I'll revisit in the future; maybe not. We'll see...

Instead of an overarching storyline like The Untamed, this series opts for like a "monster/mystery of the week" format. A new case for each episode similar to Western shows like Supernatural. Not a big fan of this format to be honest as I find it to be dull and aimless, like a distraction from the plot. Yes, there is an overarching plotline with the purple hair dude and the Black-Cloaked Envoy, but it takes a backseat to the "monsters."

I do like Old Chu and Little Guo's relationship though. I'm always a big fan of opposite-attract relationships.

Props to China for giving big-budgets to these high-concept, epic fantasy BL novels! The Untamed and now, Guardian! Even Thailand doesn't have a BL on the production level of The Untamed or Guardian, though I wished they did! Also, props to China for having these innovative BL stories unlike Thailand which is practically all like university setting (though there are some high-concept Thai BL's coming in the near future).
