"Earth Immortal?"
The gaze of the man in black landed on Qiu Tianlin with some surprise; he clearly hadn't expected there to be an Earth Immortal guarding Su's Mansion.
But Qiu Tianlin, with his sights locked onto this man possessing a strange aura and unable to discern any details about him, took the initiative to speak first: "Let her go, and I will allow you to leave."
The battles of Earth Immortals were all too easily capable of affecting the entire Capital City.
Even if the Su Mansion had already been prepared with Formations that concealed aura, others would not know that Qiu Tianlin had made a move. However, such an action would certainly expose the fact that an Earth Immortal guarded the Mansion.
This would be extremely unfavorable for Su Chengyu's activities in the Capital City thereafter.
