Sage's obsession, ignite

For example, he could try throwing Senior Skylark's head over at a place where the Scholarly Sage's obsession was relatively stronger.

He could also add Fairy Creation to the mix to strengthen the effect.

If he did all that, there was a chance he might ignite the Scholarly Sage's obsession.

If this bold plan worked, as long as the power of the Scholarly Sage lasted for a decent time, Shuhang might be able to play a key role during this event.

Song Shuhang asked, "Senior Ruler of Shadows, after this Shadow Sanctum is activated, how long can it last?"

The Ruler of Shadows replied, "It depends on the number of obsessions you activate. The quality of the obsession is related to the amount of power that can be exerted after activating Shadow Sanctum. If the quality is about the same, the number of the obsession is what determines the amount of time the technique can work."
