Gu Shenwei walked into a quiet valley. The stalker was very careful as he always kept a distance of a dozen steps away from Gu Shenwei. He could keep a close eye on Gu Shenwei by relying on the lights from the houses along the street.
This stalker was experienced. If Gu Shenwei was not that suspicious, then he would not have discovered the stalker.
The gate of a house in front of Gu Shenwei was unlatched. He stopped at the gate, checked his surroundings, pushed open the gate, entered the yard and closed the gate gently behind him. He stuck himself to the gate and listened for any sounds as he grabbed his sword hilt with his right hand.
Gu Shenwei could hear the sound of people laughing inside the house. This was a prostitute's house and she was entertaining her customer. The servant had forgotten to close the gate.
