Ruan Nuo is just a blogger who complains about abuse. When he wakes up, he transforms into a white-haired ferret from the unfinished fairy tale. He is also the alchemy guide of Demon Lord Shen Jinhan. He faces a bloodletting crisis at the beginning. Fortunately, she was bound to the "Difficulty of Mind Correction System" and relied on her unique skill of "picking things in her mouth to change her life". She kicked over the medicine bottle that night and successfully retrieved a mink's life from the pill furnace. From then on, while she was relieving the Demon Lord's old injuries by blowing up her hair, she was also crazily changing the plot under the nose of the Crazy Demon Lord: taking away the black iron order at the Fairy Gate Night Banquet and saving the heroine Su Qingyuan; the secret realm warning canceled the ambush to prevent the male protagonist Gu Yan from awakening the demon species. Diao's life is difficult, but as long as she can hug the demon king's thigh tightly, change all BE's to HE, roll around in a cute way, or pretend to be stupid to stun her, she will be fine. But Shen Jinhan gradually discovered that this little ferret seemed to be hiding a bigger secret than the Three Realms.
