Poison Doctor Double Star: Evil Lord's Palm Pet

Time travel, waste material, joy, two souls, medical poison, cute baby, evil king, double strength (cold demon + doting wife and dad, rational doctor + passionate heroine) Su Qiqi, the master of modern poison medicine, was transformed into Ye Liuli, a bullied concubine in the fantasy continent in an explosion. She thought she was the lone star chosen by heaven, but unexpectedly discovered that the soul of the original owner who "dare to love and hate" still lived in her body. From then on, one body and two souls became her biggest secret and trump card. When she was treated as an abandoned child by her family and sent to the evil cultivator's house to rejoice and die, a small doll carved in pink and jade was found in the coffin given to her: "Mother, are you awake?" Overnight, she became the demon lord's nominal wife and the cheap stepmother of a cute baby. Everyone laughs at her as the worst "waste sacrifice" in the world of cultivation, but she saves people with a silver needle in her left hand and kills gods with poison in her right hand. She joins forces with the "original owner" in her body to make a comeback in a desperate situation. And when the cold, evil, decisive demon king discovered that his "waste" wife was sometimes as calm as a doctor, sometimes as sassy as a knight, and could even... Demolish a house with his son, he fell into deep contemplation. Until he forced her into a corner and asked with red eyes: "Who are you?" She chuckled: "I can save your life, and I can also take your life."
