The Locking Infant Tower was filled with filth and repulsive objects sealing the windows and doors, such as amniotic fluid from women in labor, the monthly collected menstrual blood from the nuns in the temple, and even collected fetuses and placentas.
These things not only frighten celestial beings like a tiger, but even righteous cultivators avoid them as much as possible.
As these filthy objects can contaminate celestial magic, they can also pollute some Daoist techniques. Once contaminated by these things, many spells will lose their efficacy, and even the high heavens will be stained with filth.
Thus, when encountering such things, those who practice cultivation generally will not choose to 'test their skills' unless necessary.
Knowing there is dung on the mountain and still heading towards it, only a fool would do so.
Xu Qing, determined to handle this filthy place, must play the fool, as some tasks must be done by someone.
