While traveling aimlessly to clear his mind, he takes shelter from the rain in an unmarked cave on a remote mountain, where he encounters a young woman who looks uncannily like Tian Xiaoxia. He accidentally falls off a sheer cliff… When Sun Shaoping wakes up, he discovers that he has become Zhao Yicai once again…
