Time Raiders covers all of The Lost Tomb (2015), as well as the first part of The Lost Tomb 2 (2019).
So if you want to know what happens next, you should start with TLT2 (with Hou Minghao & Cheng Yi) and continue from there.

Chronologically, it fits between the first season of The Mystic Nine and this drama (Time Raiders).

You're welcome!
Please let me know if you find this song online somewhere, I really like it as well.

There are three songs listed in the end credits of the drama. The song you're looking for should be 废墟 (Ruins) by 郑楠 (Zheng Nan).
Zheng Nan is the same artist who made the song that is played during the end credits of Tibetan Sea Flower/Adventure Behind the Bronze Door.

Literally the first thing he says to Wu Xie when they meet again is: "You have aged."
Which, coming from Xiaoge, can mean anything and everything. My guess is he simply knows and can see the years of hardships in him.

Yeah. He's in his late 30s when they see each other again.
He's lost a lot of his innocence by then because he had to learn to survive without Xiaoge, and has turned into a person you don't want to mess with.

Her name is Wang Yunzhi. Weird that she wasn't added with the rest.

The first time he went in during the Heavenly Palace arc (right before UN), he didn't stay for long. The second time he went (takes place between UN and most of ABtBD), he's gone for 10 years.

He went in more than once over the course of the novels. One time before Ultimate Note, during the Heavenly Palace arc, and a second time after. The second time is described in the final volume of the main novel series that hasn't been adapted yet.
Wu Xie looks back on those events in "Adventure Behind the Bronze Door".
They appear as flashbacks in which the young Wu Xie is played by Xu Zhenxuan for the first time.

I use the WeTV app.
I paid extra for the express package, though.

Skill issue.
I really enjoyed the adventure AND I'm shipping them. It's possible to do both. <3

You're welcome. :)

I just have slightly too much money to spare and no self-control when it comes to these adaptations. 😂

Tell me about it. My first marathon of all the DMBJ adaptations sure was a confusing one. 🫠

I very much doubt they will be skipped because they are really important to the story, especially Heavenly Palace.
Looking at all those promo pics of the Iron Triangle in the snow, my guess is that those parts have already been filmed and are in post-production.
Adding those two arcs would then cover the entire plots of TLT, TLT2 and TLT2: Heavenly Palace on the Clouds combined.

And then come the events of UN and we're back on track.

There are two more story arcs before UN. I'm not sure if they were also filmed and just haven't been released yet (with these same actors here I mean).

Not exactly a sequel, because the last volume of the main novel series has never been adapted. There are a few flashback scenes that show important moments from that time, though, those are the ones that introduced Xu Zhenxuan as young Wu Xie back then (and that immediately convinced me that he's indeed perfect for the role).
Wu Xie and ZQL meet again later, before ZQL leaves for good and enters the Bronze Door once more, this time for ten years.
Wu Xie has to survive the insane world of grave robbers without him in that time and it's taking a heavy toll on him (he's also missing him, like, A LOT).
That's why Wu Xie is portrayed by much older actors later. Because when ZQL finally returns he's already around 40.

It's not in the book.

Watched the scene in which they find Wang Zanghai—or what's left of him—and the fact that the man has been dead for centuries and is STILL messing with them was just glorious.
I especially liked the bit where he smiles when Xiaoge bows to his corpse, and suddenly the whole room lights up. That was pretty awesome and really well done on a technical level.

I loved that part about them finding Zanghai in The Lost Tomb 2 as well, it was one of the more memorable scenes.

Very good! Very faithful adaptation. Excellent Iron Triangle, too, 10/10, great acting and great chemistry between the three of them, especially in the second story arc.
Would (and will) watch again.
