Awe of the City Lord's Mansion did not mean fear of it. The reason he hadn't made a move earlier inside the mansion was simply because an Emperor Realm expert resided there. He could not possibly match an Emperor Realm expert; even if he eventually managed to slay Su Hao, escaping the City Lord's Mansion alive would be exceedingly difficult.
Unless he continued to use the Divine Dragon's Bloodline and unleashed the Blood Demon Transformation, but the backlash from that was terrifying. The injuries from the previous backlash hadn't even healed yet; if he had to endure that once more, he could go straight to hell.
This was the real reason why he hadn't struck inside the City Lord's Mansion. He had originally assumed Su Hao would come out this time, and as long as he could successfully kill Su Hao, he could leave Huanhai City, leaving the City Lord's Mansion completely powerless to stop him.
