Wenjiu, a master of both poison and medicine, was reborn and returned to the year when he was bullied by everyone. In her last life, she repaid evil with kindness and died without a complete body. In this life, she chose to poison people. She refined her poison skills to the point of transformation, poisoning invisible and killing people silently. The people who had harmed her died suddenly and inexplicably one by one. The entire world of cultivation changed their minds after hearing about "Wen" and called her the "devil". Wenjiu accepted the title with a smile, until the sword immortal who was invulnerable to all poisons came to his door: "I heard that your poison even scares gods?"
