Lin Wu watched the disciples fail and fail thousands of times as they went through the trials. He ended up skipping a lot of the parts but finally reached the point where they had completed the final trial.
Doing all this had taken them ten years, and it was not an easy task for them.
"The Sky Bright Daoist certainly designed these to test the trial contenders in the most sadistic way possible." Lin Wu understood.
From all the trials, the one thing Lin Wu had learned was the fact that the trials were random and the aim of the trial was not given. The disciples had to figure it out all on their own through the mistakes they made.
Many times they struggled for months on end, only to learn that what they thought was the solution was not that all.
For example, in the sixth trial, the disciples had thought that they needed to protect a certain person that they come across in the trial. They did thousands of attempts and died many times.
