The lost tomb 2 continuous from the lost tomb 1, but the lost tomb 2 have a bit more story about mystic nine than lost tomb 1. I personally recommend to watch mystic nine first

For the cast, i personally love all the cast in this story because the all match with the characters of this story from main role to support role especially Neo Hou, he is the best wu xie after i watch all lost tomb until now except the reunion. I became fans of Neo because of this story.

The story have a lot element like suprise,horror,funny, and sad
So personally recommended and i already rewatch it twice
