Qi Sha attacks the Day Master with the same polarity — the fiercest pressure and tempering star: boldness, ambition, crisis-awareness, and the brutal side of authority.
Qi Sha must be controlled or transformed: with Eating God restraining it or Resource transforming it, pressure becomes authority and drive; unchecked, it becomes drain, injury and disputes. A strong Day Master can bear it; a weak one must protect itself first.
