Ling Hua hadn't slept for two days and a night and had had two arguments with Yan Qing, the emotional toll of which was significant. She was indeed exhausted and deeply sleepy. Thus, when she lay back on her bed, deciding not to think about anything, she fell asleep instantly.
Her sleep was deep, and she didn't know that Yan Qing had left his room that afternoon and gone out to drink in the rain.
Hence, an hour later, when she was awoken by a series of footsteps, she turned over, intending to continue sleeping, but was jolted awake as Wangshu pushed open the door to the outer drawing hall and stood at the entrance of the Warm Pavilion. Through the door, he addressed her inside, "Mistress, Young Marquis encountered an assassination attempt at Jinzun Square, the perpetrator being Mister Zhang Er, who has now been captured by Yun Luo and taken back to the Governor's Office," he said, and Ling Hua abruptly sat up.
