The leader of the black-robed figures was none other than White Tiger.
Two days ago, they had covertly entered Cathay and, after a period of investigation, learned that Lu Chuan was from Jiangbei Province, so they came here.
Living overseas for many years, White Tiger had grown quite unfamiliar with the domestic situation, and was utterly shocked by the rapid development of the cities here.
Furthermore, the overseas life being dull, White Tiger, despite being a member of the Law Enforcers, was essentially still a girl. Upon seeing the bustling pedestrian street, she found herself reluctant to move on and thus persuaded the other three Law Enforcers to have some fun on the pedestrian street before continuing their search for Lu Chuan.
This coincidentally allowed them to witness the scene of "Lu Chuan" teaching Eldest Young Master Zheng a lesson, and then saw "Lu Chuan" entering a deserted alley with Han Qingci, prompting them to spring into action.
