Su Qingtang, a spiritual plant medicine boy, was recruited into the Shangqing Sect because of his ability to identify thousand-year-old spiritual herbs. He was accidentally bound to the "Flower Protection Deed" with Xie Chengyu, the cold immortal king. The two went from being "forced to walk together" to gradually falling in love, and in the process they uncovered the cause and effect of their past lives - Qingtang was originally Xie Chengyu's fallen Taoist companion. Due to a trace of his remnant soul, Xie Chengyu entered reincarnation, and Xie Chengyu had to wait a hundred years just to make up for his regrets. When Qingtang gradually awakens the memory of his past life, but is punished by heaven because of his "incomplete soul", Xie Chengyu sacrifices his life to protect him, and finally both sides go to resolve the disaster and go to the immortal road together. The main line is strong sweet pets + high interaction, interspersed with spiritual plant puzzles, sect games, and past and present dual lines. The exciting points are concentrated in the "contrast pet of the fairy king", "the drug boy's counterattack and slap in the face" and "causal and closed-loop redemption".
