Free portal to Timeless Island and save 7500 timeless coins

I think its definitely not meant to be like this, but its way around game mechanics and kinda use it.
Required is: Emeror Shaohao Honored (this will access).

Basicly you will buy the trinket from vendor: Mistweaver KU: [Time-Lost Artifact]

You can then hs, portal or whatever use to go anywhere for about two hours. Then portal back to timeless island and vendor the item to nearest vendor and get the 7500 coins back.



You can do this as many times you want. 7500 isnt alot, but why spend it if you can get around of it.
