Zheng Lancen returned from studying abroad and brought back money and honors that would make her mother Hua Rong happy and happy, only to find that her mother disappeared six months ago. Zheng Lancen, who refused to accept reality, created the phantom of her mother until the elf Xian Yuan San broke the phantom and told her that Hua Rong had gone to "Zhu'anmen".
I would rather go to Zhu'anmen and have nothing to do when I come back.
To the human world, Zhu'anmen is a beautiful place with beautiful mountains and rivers, but to the divine world, it is a deep swamp that will never be restored. Zheng Lan was ashamed of the suffering she had suffered for her mother for many years and decided to spend the rest of her life repaying it, but she died unexpectedly. But Yuan San accidentally entered Zheng Lancen's body, and one immortal and one corpse merged into one.
In order to get out of Zhu'anmen, Zheng Lancen of the third generation of the Yuan Dynasty paid it back to his mother. Walking around in the secular world, it is impossible to escape the word love. She thinks she has seen everything in the world, and Yuan San is very confident in this. She can definitely design a perfect life for Hua Rong, without even a hint of love.
But as Junichi Watanabe said: "I thought I had been mentally prepared for it, but everything from my behavior to what I thought would become completely different."
Yuan San was trying to prevent others from getting half of the love, but in the end he got all the love.
