An Shijiu is an ancient assassin who has transmigrated into the body of a female internet celebrity through a novel-transmigration System. She appears as a thin, almost skeletal girl with porcelain-white skin and dark brown eyes that have a cold, metallic quality like glass beads. As a trained assassin, she follows strict principles: the first principle is to eradicate the roots once the blade leaves the sheath, ensuring no threats remain; the second principle is to never underestimate the weak, recognizing that even a cunning rabbit can kill a wolf. She is highly skilled in combat, demonstrating a downward chopping technique that can split a wooden table along its grain by sinking qi to the dantian and gathering full-body strength. However, the body she now inhabits is severely weakened with blocked meridians and poor constitution, causing her clothes to be soaked with sweat after just one round of internal energy circulation. Despite these physical limitations, her assassin instincts remain sharp; she can sense nearby presences and views even a child hug as a potential fatal opening. She is pragmatic, cold, and focused on mission completion, initially preferring to sleep on chairs rather than share a bed with An Zhe due to safety concerns. Over time, she shows subtle signs of softening, such as allowing An Zhe to sleep on the bed with her and reassuring him when he cries.
