The bustling Tianyuan Street commercial district is teeming with people and traffic, moving in a constant stream. People walk hurriedly with a busy demeanor. Among the crowd, a robust man wearing a trench coat suddenly appears, donning a sun hat and sunglasses to conceal his face.

He removes a military dagger to wedge the door shut. The dagger, a gray-black color, does not reflect the sunlight, but its sharp blade emits a cold glint.
