"Perhaps this world is like this. There is no love, no compassion, no companions. No one is worth your hurt. It is enough for you to have me. Changxi."
"Xi, maybe you think I am a cold and heartless person. Yes, I am indeed a cold and heartless person. But when I meet you in the rest of my life, I feel that no matter how cold I am, it will be too late to regret."
"Gu Changxi, I will never abandon you in this life. If I, Gu Jianshen, abandon Gu Changxi, I will be struck by lightning that day."
"I will help you become the prince, but there is one condition. I must leave you."
