In the pitch-black night, a guard on night duty went to a weedy area behind the village to relieve himself. He stumbled on something and fell headfirst into a ravine ahead.
"Aah!"
As he fell, the guard instinctively screamed. His head was broken, and the scream abruptly stopped.
"What happened?"
"What's going on?"
Hearing the commotion, two other guards on night duty quickly came to investigate. They looked around but saw no one until a voice came from the ravine.
"I'm fine, I just accidentally fell into this ravine and bruised my head."
When the two guards heard this, they remarked, "It's good that you're fine. Get up and apply some medicine to your head wound," and then walked away.
