I wonder what Meizhen's trial will be, or lead to. The same for Lady Cai, or Sun Liling. Has the trial already occurred for Lady Cai (given Duchess Cai was here and had personal time with Cai) or is it yet to come?
How intense does the trial/tribulation need to be in order to have a chance at triggering an insight? Does increasing the intensity increase the chances of an advanced insight?
Either way, it certainly seems like Meizhen's statement in the previous thread about how conflict is necessary for growth is true beyond a simple worldview. In order to pass beyond middling green and reach the heights of cultivation, there needs to be a conflict to overcome. A trial that pits you against a wall that you must break through in order to continue your advancement.
It'll be interesting to see what advanced insight (if we can even see it) will come from the trials that Meizhen must face. Her powerful domain already has problems with control, and if it gets more powerful from an insight that control might become even more difficult to acquire.
Anyway, assuming Ling Qi survives, there will be interesting times ahead.
