Zhao Yu awoke with a start from his nightmare. It was already four in the morning. The sky was still dark outside. It was a dark night with no wind, and it was stuffy in the house. Zhao Yu was sweating all over.
"That's damn scary! Like the saying, 'what you think about in the day, you will dream of at night.' Investigating cases like about an ancient tomb with a dead victim makes me feel disheartened…" Zhao Yu thought. He turned on his table lamp and took a sip of water. He wanted to turn on the air conditioner to go back to sleep in peace, but he suddenly recalled the vase from the Ming Dynasty that he left outside his room.
