Long, long ago, there was a wealthy merchant. He possessed countless riches, had numerous wives and concubines, and even built an enormous mansion to enjoy his luxury life.
However, the merchant could never have dreamed that one day a horrific tragedy would occur. His mansion was engulfed in a raging inferno; his wives, his concubines, his whole family of more than fifty people all laid dead in pools of blood.
A small concubine of the merchant looked at the corpses littered on the ground. She gazed at the scene of blood flowing like a river, then at her hands covered in fresh blood, and the knife in her hand. She was bewildered by what had happened, utterly dazed.
The mansion was burning more vigorously, and the intense heat kept closing in, but the concubine seemed oblivious to it, standing still in a stupor.
"Well done. Those damn men deserve a harsh lesson," a woman appeared, seemingly taking pleasure in the sight of the panicked concubine.
