Everyone says it is better to offend the King of Hell than the Lord of Shuangyue. Shen Shuangxiao is a presence that strikes fear throughout the entire Jianghu. Rumor has it that he is unpredictable in his killing and bloodthirsty and cruel. Su Wanhuang, a modern medical school intern, somehow time-traveled into this martial arts world. Originally, she only wanted to wholeheartedly save up enough silver and peacefully survive. But the storms in Jianghu rise again, and the peerless martial arts manual "Chen Shuang Jue" reappears in the human world. She originally wanted to stay out of it, but step by step she stepped into the mist of Shuangyue Pavilion, stumbling right beside that lord feared by all mortals, and the destined entanglements of the two begin from here.
