Cang Shuang was sold into prostitution as a child and had always been cautious. At last, she spotted a chance to escape, only to blunder into the room of Qi Ji, the regent of the current dynasty.
He was a notorious killer, vicious and ruthless. She'd be lucky if he didn't kill her, so how could she expect him to save her?
Fortunately, the heavens were watching over her. For some unknown reason, Qi Ji was suffering from an unbearable headache and was on the verge of passing out.
Cang Shuang took advantage of him and forced him to drink wine laced with a sleeping drug. Before the killer passed out, he forced some down her throat too. Luckily, she'd taken the antidote beforehand.
She had it all figured out. If they spent the night in the same room, she could escape the brothel keeper in the morning, before he woke up, by claiming she'd slept with him, right?
Who knew the wine hadn't been laced with a sleeping drug at all?
It was Drunk for Three Thousand Years, a poison from the Western Regions. Its victims became trapped in a dream shaped by their deepest obsession, unable to wake until it was fulfilled. The two of them had entered the dream together.
Cang Shuang thought she was done for, but then she discovered that she and Qi Ji had switched bodies. She had become Qi Ji, a wealthy merchant in the dream, while Qi Ji had become her, a courtesan dependent on her for everything.
Even better, Qi Ji seemed to have lost his memory.
Cang Shuang immediately decided to take advantage of him again. In the dream, she cared for Qi Ji in every possible way, showering him with ardent love until she finally won his heart.
That still wasn't enough. When his obsession was about to be fulfilled and the dream was about to fade, Cang Shuang seized her chance to take a blade for Qi Ji. Covered in blood, she died in his arms. As she lay dying, she thought she felt a tear fall on her face.
When she woke, Cang Shuang didn't dare linger. Using Qi Ji's name and influence, she bought her freedom and left without a backward glance.
Who could have known that before long, the killer would come looking for her...
Qi Ji had three great humiliations in his life.
First, while suffering a bout of poison, a woman took advantage of him and drugged him, leaving him helpless.
Second, while he had amnesia, that woman kept him as her lover, toyed with his heart and body, and lured him deeper and deeper into obsession. Then, just as he could no longer restrain his feelings, she faked her death right in front of him. He could never forget the sight of the woman he loved, covered in blood, taking her last breath in his arms. Every time he remembered it, his heart was torn apart.
Third, when he woke from the dream, that woman had run away and abandoned him. She even dared to pretend nothing had happened when he came looking for her.
Ha.
