Hi, it's easier to drop a note on discord if you want help (as I generally only check places like this occasionally).
The process with moving on from that point is pretty straight forward.
As the task says, you need 1,300 converted qi. You get converted qi by acquiring world qi, and then using the qi conversion option on the meditation menu.
Once you have that amount or more, and try to convert some qi you will trigger the next event.
Mai also explains this if you speak to her, stating that it's "very important" to convert your qi during this time.

except they're showing that's what occurred. To guess, it's that you fully expected people to just collect qi and then convert it then talk to her rather than spending it? Cause after that point, I literally got shown characters I was unaware of purely because the timed events activated and the quest *refused* to be completed.
