章 255: Experimentals

Caroline thought for a moment, then touched her waist, untied the thin belt inside, and pulled out a metal thread that was wrapped into a chopstick thick rope. There was a small hook at the end.

This was a climbing tool that she had specially found a craftsman to make through Will Sr.'s connections. It came in handy now.

Caroline put the belt back in its original position, then stared at the ventilation window to confirm the position of the buckle inside. Then, she threw the rope in her hand, and the metal hook flew out. With a slight 'ding', it hit the plastic board on the vent.

The gap was too narrow, and the hook was slightly off, so it failed to get in.

However, Caroline wasn't discouraged. After retracting the hook, she carefully considered the angle and threw it out again. This time, the hook successfully stuck in and successfully formed the buckle.
