The entire city was filled with the elderly, weak, sick, and disabled, presenting a bleak and dilapidated scene. As night fell, Wenning deliberately lit the lamp, attracting ghostly shadows.Just as he was about to capture him, a blue sword light struck, and the black figure took the opportunity to escape. Wen Ning looked up and saw a familiar figure rushing in from outside the door. It was his old acquaintance, Lan Sizhuo, a descendant of the Lan family.Subsequently, Wen Ning and Lan Sizhu joined hands and, through unremitting efforts, finally solved the mystery, captured the mastermind behind the scenes, and returned a peaceful world to the people.
