The system bound to Wen Ran, referred to disparagingly as Zha Zha by her. It is a Scumbag System tasked with helping Wen Ran complete missions in the novel world. Unlike previous transactional bindings with hosts seeking bodily resurrection or billions, this system is unusually conscientious and protective. It tracks affection points displayed as green numbers above characters' heads. It fears Wen Ran might be ensnared by Si Yan again and promised to expend all its energy to protect her if the mission fails, which would result in elimination of both task-taker and system.
