After Suyou succeeded the Demon Lord, the Demon Realm collapsed three times a month. Even her close confidants advised her to "grab a Wood Spirit Root Immortal to repair the Five Elements." She disguised herself and sneaked into the fairy world to look for the "wood mending tool man", but she accidentally spotted Qi Yan, a disciple of the Guanming Sect - a man who looked like a loser, but was actually a strong man with hidden wood spiritual roots who could talk to plants and trees.
Qi Yan was being forced to get married by his sect, and when Suyou came to visit him, he took the initiative to propose a "contract Taoist couple": he would help her stabilize the five elements, and she would help him get out of the engagement. Su You originally only wanted to use him, but found that every time he got close to Qi Yan, his withered magic plants would sprout, and he could even force strange flowers in the demon world to bloom with his bare hands.
During the relationship, Suyou's "Crazy Punishing Demon Lord" character frequently overturned: he would fight off the provocative demon generals for Qi Yan, secretly learn the etiquette of the immortal sect, and when Qi Yan was being made trouble by the immortal sect, he would carry the demon sword directly to the gate of Guanming Sect and shout, "I can only bully my Taoist companion." Qi Yan also gradually revealed his strength, using the power of the wood spirit to help Suyou repair the demon realm. However, during a sacrifice, he discovered that the fate of the two had been bound thousands of years ago. He was actually the reincarnation of the ancient wood god who died in order to complete the five elements for the demon king.
When the Immortal Sect surrounded and suppressed Qi Yan on the grounds of "colluding with the demons", Suyou tore apart the barrier to protect him, but unexpectedly triggered the resonance of the five elements - it turns out that the best "method of mending the elements" is never use, but the intention to rush in both directions.
