Bai Yun went out after he completed the trial. He returned to the main desk to continue taking the other trials. The points would be automatically allotted to his token. Otherwise, he only needed to go there if there were any extra rewards, which there weren't in this case.
Once he was done with the first trial, Bai Yun went to do the second trial. The second trial was to walk the dao path. The second trial was similar to the first round of the freshmen competition. You simply had to walk along the path while the pressure of the dao fell on you.
