After trying for so many years i finally got sub 5 seconds, which means it's possible to go even lower like 4 seconds since as you can see my character had to go back to deal the final blow.

i'll test stage 1-3 and see if there is an unlimited number of enemies until you reach a certain point because it seems like you have to wait until the ship arrives at a certain point.

During my run i found that the In-Game timer still goes on during the background. This happens during when players exit the stage and cutscenes. Should it be consider or not?

The rules say In-Game timer but it is often wrong and will not work during certain times like in one of my run. I uploaded a whole run so everyone can understand what i mean:

A speedrun from the far checkpoint of Liyue harbor to mondstadt gates, this should be challenging and can be faster with certain items. As the game gets more maps and items, we can see other races to mondstadt or towns.

i'm planning on test running this to see how well it goes, the world is open but players will need to consider the landscape for the fastest run.
