In "Alternative", it is said that Xie Bi 'an intended to draw lots for three husbands from the beginning. What is his intention? Did it end with Mei Qing guarding his bones?

The end result is that Hanako Xiao died, and Mei Qing remembered the memory of past lives. Hanako is a fairy in the sky, and Mei Qing is a demon. Mei Qing approached Hua Zixiao in order to complete the task, but unconsciously fell in love with him. Later, things in the underworld were exposed, and God tried to kill Mei Qing. Hua Zixiao killed God to save Mei Qing and was punished by God. His soul went to the six major departments of the Karma Wheel, his soul went to hell, and Mei Qing was taken away in his lifetime. Finally, Hanako Xiao died, and Mei Qing remembered her previous life. Xie Bi 'an should finally be resurrected and continue to serve in the underworld.
