Su Yijia cautiously observed the pitfall and prodded the steel spikes with a tree branch to ensure they wouldn't easily come loose. Her suspicions were confirmed: someone had set this trap to protect something valuable and ensure that they could find it when coming back again.

Why didn't he come back again?
