If I attack directly, I'm afraid I'll be blocked. A stealth attack would be better.
Nan An thought in her heart.
She began to contemplate what weapon could give her opponent absolutely no time to react, a one-strike kill.
As she descended further, the passage gradually became more spacious, and correspondingly, the items stored there became bigger and more enigmatic.
The sound of breathing behind her was very displeasing to Nan An, so she searched her body and found something suitable for a surprise attack.
A lock opening tool.
The sharp end, if plunged directly into a person's vulnerable spot, would not necessarily cause instant death, but would definitely temporarily incapacitate them. The downside was also clear; if the stealth attack failed, the lock opening tool would be almost useless as a weapon.
The two walked for a while, and Nan An made idle conversation.
All was well until... a painting appeared on the wall to the left.
