Six optional team skills, others are negotiable, except for "Immortal Tour" which is a must-have for Yan Qing. Not only because it helps the small number shuttle back and forth, but also because it is the best way for him to descend into the present world.
To this day, Yan Qing still hasn't used the 'Teleportation' of the Thief's House to see outside, even though through the Teleportation Gate he can vaguely see that the outside is probably an uninhabited woodland.
Not even once!
Thinking about it carefully, it's quite absurd. If this is a game, then Yan Qing is equivalent to logging into the game and staying in the newbie safe house, never once having explored the outside. He doesn't know where the 'initial teleportation location' is anchored, nor is he interested in exploring.
