In the Tianzhu building, Xian Feng and Shi Qingzhuang stood side by side on the balcony as they observed Zhang Fei and Zhang Lin using their senses. Behind them, a young man and a young woman stood, exchanging confused glances, their confusion heightened by the two's attitudes.

The young man has shoulder-length black hair, black eyes, a sharp chin, and a not-so-muscular figure. His inner clothing is white, and his outer clothing is blue.
