There is a note in the Book of Heaven. Yuansheng Xingjun once asked Yue Lao for advice: A single word of love in this world can kill time and reverse life and death. But why?
But Yue Lao replied: Only the living beings of fireworks can understand the word love, and the people of the immortal family are the most ruthless.
"It is said that the immortal family is free and happy, and they have lived for hundreds of lives outside of reincarnation. The world doesn't know it. How depressing it is. What do you think, Mr. Xing?"
"Me?" Yuansheng Xingjun lowered his eyes for a moment, "I don't understand. I really don't know anything about this world except slaying demons."
