Wuyun Trading Group is a trading group with Shugu as a member, and you can buy props from it in the game (Shugu is commonly known as mouse ... = =).

That's a task, and you have to go through all the fortresses to complete it. I remember the opportunity to get ahead (I forgot the name of npc-look it up more, it seems to be picked up in the dark island of obs). Heading movement speed +5, running is quite easy to use.
