Yun Shouxin, the last Taoist protector in the immortal world, abides by the ancient rituals and prevented countless disasters for Xinglan, the "son of destiny", but what he got in exchange was the contempt of the other party for his talent and arrogance and the betrayal of the fallen demon, and his Taoist heart was broken.
He was living in the mortal world and met Ye Qingyu, a girl who was regarded as a "waste". Her tenacity and kindness actually rekindled the faint light of his collapsed Taoist heart. Yun Shouxin accidentally discovered that Ye Qingyu's spiritual root was sealed, and underneath the seal was a rare spiritual root of chaos - the real "trend of the times."
He decided to change the object of protection and help Ye Qingyu break the seal and grow up. The two of them moved from the mortal world to the fairy world, facing the fallen demon's stars and raging demonic tide. This protection across immortality will eventually reveal the truth about destiny: the so-called destiny is never destined, but the will of people's hearts.
