Many times Song Yu really can't tell what is reality and what is illusion. Some of the sweet dreams that he thought were realities did not happen (marrying the Wushan goddess Yao Ji and reaching the pinnacle of life), while other terrible dreams became reality (a beauty--a male--Rong Guang appeared out of nowhere and entangled him).
Life is painful, and death is also painful. Therefore, he had to escape in the cracks of time and said to everyone he met:
"If you see a stunningly beautiful white-haired animal, please don't say you've met me."
"Huh? Who am I, you ask?"
"I am Song Yu. I am not Song Ziyuan or Gonggong."
"You asked me why I ran away? Because I provoked a man I shouldn't have provoked. His name is Rong Guang."
"Stop talking and run away. I'll see you in my dream if I'm destined to."
