It's fine.
That's the most accurate and positive thing I can say about this season.
Daomu still remains the less good tomb raider series for many reasons (I'll list a few at the end), but this series is actually quite watchable, unlike Tomb of the Sea.
There's less clan politics and more tomb raiding, which is good in my book! And the tombs look quite good, I gotta say - the sets and CG are quite competent. (CG animals still look terrible, but that's just normal Cdrama stuff)
Honestly, the story is by far the weakest point - there's very little structure, no themes or character arcs, it's all plot. Stuff just happens in a mostly linear way.
And the usual bugbears appear - characters show up with 0 set up and leave the story with no payoff.
Remember Wu Xie's Gollum childhood friend? Yeah, we'll never hear from him again. Remember those rival tomb robbers? Yeah they just die. Look, it's the Shades guy from Tomb of the Sea! Why is he there? Who knows? We'll never find out, he's just suddenly there.
Can they actually resolve anything in 40 frikkin episodes? Nope. Will they end it with an out of nowhere cliffhanger? YOU BETCHA!
And what's up with that end part in the Snow Village, which is eerily similar to Eagles and Youngster?! Is it just one tomb writer ripping off another tomb writer? Or are they both based on some real world local story?! (seriously - snow village near a gold mine? A forbidden mountain area that poisons people? Previous expedition disappeared? A young local man whose sister is a great hunter against local custom?!)
The actors are...fine. Fatty is the best, which is somehow 100% legit standard in all these tomb raiding shows. Wu Xie has a very narrow range of Cheery optimistic --- Puzzled and Inquisitive --- Action boy saving his friends. He's fine.
Little Brother is...there. (honestly, not the worst actor to do this character, but also stiff as a wooden plank, as most of them are. The guy in Time Raiders remains the best one.)
Uncle guy is played by the same guy as boss Ma in TotS, which is not confusing, just weird.

TL;DR: If you're watching these to find out what the big mystery is, don't waste your time and just watch Tomb of the Sea. (and even then, I don't guarantee it'll make much sense)
It's solid tomb raiding for most of the time, with a decent dose of humour and mostly silly action.
It's fine.

(PS: Reasons why Candle in the Tomb is better than Daomu? This series once again reminded me how differently the two franchises treat local people and ethnic minorities during these tomb raiding adventures. See, in Daomu they're mostly portrayed as superstitious country hicks, weirdos or outright idiots. They also betray or mistreat the main characters most of the time.
In CitT? They're shown as interesting cool and caring people who just live differently. They have actual character instead of insulting caricatures.
I think this ties into the whole framing of the two stories - where in CitT the main characters are underdogs with barely anything to their names, the guys in Daomu are members of rich gangster clans who own massive houses, drive expensive cars and dress like clowns in what's supposed to pass for high fashion I guess. Like Wuxie is kind of a sweet boy, but his idea of a problem is "How can I afford this massively expensive artifact at this auction? Oh I know, my friend will sell one of his multiple mansions.".
I could go on.)
