I honestly feel bad about rating it so low, since it had quite a few enjoyable elements and the first half was exactly what I always look for in Tomb dramas, but there were a few too many flaws that I just cannot ignore.

Starting from the things I liked.
Iron Triangle as one of the best trios ever created. A typical case of characters representing a heart, body and brain, but it never felt limiting in how they were interacting with each other. All of their scenes together were easily the best in the whole show.

Likable female characters with their own goals and ideas. We all know how limited in that aspect are Tomb dramas. Here we got a variety of women with unique personalities and perspectives.

The acting was great. I think Chen Ming Hao is my favorite Wang Pang Zi at the moment. This character is always hit or miss - I either like them, or hate them. Here, he was probably one of my favorites.

Another positive thing was proper lighting. Big props to the team for making the caves/warehouses/underwater scenes look dim, but not ridiculously dark when the viewers can’t see anything. A few more candles or flashlights as the light source is all it takes for the viewers to not question how bright some places might look. The whole production quality was great - the set designs, costumes (excluding Glasses, I just cannot deal with that outfit), camera angles - all working well to create nice pictures.

To the less enjoyable things.
First and second half of the show felt like completely different dramas. Not only did the plot seem too loosely connected, the main cast completely changed. We literally cut from the show the characters we followed at first.

While I appreciate the female characters, I am also a bit sad how all of them were put in the context of being romantic interests. No one watches the Tomb series for romance, this is really unnecessary.

Second half was painfully repetitive and failed to make me care about the plot progression and even the characters safety. I am sorry, but how many times can I watch Wuxie do exactly the same thing over and over again in more or less the same manner in a boring environment, surrounded by barely established characters?

Wuxie being sick. Oh god, too many times it felt like watching a wuxia with male lead being poisoned and coughing blood - so dramatic for no reason, because we all know he is not going to die. My issue was how they presented it as something dangerous, but it never felt really limiting. All the potential issues always showed up after he was done with whatever task he had to accomplish.

While I do believe everyone in the cast did an amazing job, I am also a bit bored with Zhu Yi Long (don’t kill me). There is not enough variety in the roles he takes and his portrayal of them. Sure, I only saw a few of his dramas, but it always feels like a similar character just put in a different context.

Overall, it was not bad, but felt too “all over the place”.
