Overworked office drone Ji Mian transmigrated into a book, becoming Zhutian, the life-bound sword of the cultivation world's greatest villain, the Demon Venerable. It was a vicious blade that had drunk countless drops of blood and was about to help its master destroy the world.
The good news: she's a sword spirit now, so she can't die.
The bad news: the Demon Venerable plans to massacre a city today, and she's just bonded with the [Sword Spirit Management System], which can forcibly control her master's body for one hour in a crisis!
As her deranged master headed for the city gates with sword in hand, Ji Mian possessed him and launched her master plan to reform the villain:
She taught the Saintess of the Hehuan Sect the Heartless Spell;
She pinned her nemesis down and forced him to take health supplements;
She helped a blind old lady cross the street...
The demonic cultivators went wild. “Has the Venerable been possessed?” “No, this must be some new kind of intimidation tactic!”
The Demon Venerable Ji Wushe, forced to play along, soon noticed that every time he came to after losing control, he was either hugging a spirit rabbit and grinning foolishly or bringing comfort to his enemies.
Then one day, he pretended to be asleep and heard the sword spirit in his body muttering: “If you keep killing people, I'll sell your cross-dressing portrait to Demonic Sect Gossip...”
Ji Wushe chuckled, gripping the hilt. “How are you finding my body, A Zhu? Does it suit you?”
Ji Mian: I'm done for. He's figured out who I am!
It's good to watch. It's good to watch. The relationship and the plot are both good. It doesn't drag on.
