Situ Zhong, a disciple of the Shushan School, is extremely talented in martial arts but cynical. He plays with the world and created his own "Bacchus" sword technique. Since the thirteenth day of the twelfth lunar month two years ago, Situ Zhong has dreamed of his beloved woman dying tragically in front of him every night, and has no memory of the three days before the thirteenth day of the twelfth lunar month that year.
