To her surprise, she finds him cooking a demon lord into soup and forcing the subdued demon king Jiang Taibai to taste it. In a relaxed atmosphere, Jin Lanyue sternly questions Zhang Xi why he unsealed the demon ancestor. Zhang Xi calmly admits it and reveals his terrifying strength, having reached the "Half-Step Immortal Realm," declaring, "I am invincible below the Immortal Realm."
