The alchemy genius transformed into a deposed junior sister and found that the alchemy skills in this world were crude and the poison was completely useless. She uses poison to enter the Tao, and to save one person, she has to kill one person (the villain). The righteous way crusades against her, the Demon Lord begs her to poison her enemies, and the Immortals kneel down and beg her to poison the demons outside the realm. In the end, she poisoned Tiandao with a cup of "immortal-killing tea".
