Shi Nian looked at the pitiful appearance of the little girl and also felt a headache coming on.
This little girl knew the secret of her Sky Escape Technique; for safety's sake, she couldn't just let her go at will.
Otherwise, if the news spread out, it would probably cause her some trouble, big or small.
But to kill her?
That was not something Shi Nian could bring herself to do.
Shi Nian stared at the little girl for a long time, until the girl felt her scalp tingle, then she spoke softly, "Come, make an oath to the Heavenly Dao. Never reveal my secret technique. Once you make the oath, you can leave."
Just like that?
The little girl's eyes lit up, she quickly agreed, and then under Shi Nian's gaze, she sincerely made her oath to the Heavenly Dao.
This Heavenly Dao oath wasn't one hundred percent foolproof; should a powerful being intervene and bear the backlash of the oath for the little girl, she could naturally break the oath.
