Gu Yanzhi followed the route in her memory, not forgetting to drop a few timed bombs along the way.
Yan Yu seemed to have disappeared, allowing Gu Yanzhi to move smoothly. She encountered no one till she reached the stairwell where the window was located.
Gu Yanzhi used a hammer to break the window, and the sound of shattering glass echoed throughout the room.
The window was small, just enough for one person to crawl through. Gu Yanzhi skillfully tied a safety rope for high-altitude work around herself, then hooked the other end of the rope to the staircase.
Just as Gu Yanzhi had secured the rope, she heard hurried footsteps approaching—probably Yan Yu, alerted by the noise of the breaking glass.
Ignoring the shards of glass still clinging to the window, Gu Yanzhi quickly climbed out and slid down the rope. The sharp glass cut through her delicate skin, and blood dripped down, drying quickly in the scorching sun before it could hit the ground.
