Fighting: Poisonous Immortal in Disaster

In this life, she is no longer the girl who can only stand behind him. She is the master of disaster who has perfected her poisonous body and is invulnerable to all poisons. Whoever dared to touch him, she would leave his body intact. Xiao Yan looked at the smiling girl behind him and felt that something was wrong. "Little Medical Fairy Girl, have we... Known each other before?" She raised her eyebrows and said, "I don't know him. But we will know him for a long time in the future." Just—— "Xian'er, what's so good about that boy from the Xiao family? Is he as good-looking as me?" Yao Qianxun bit into the candied haws, feeling aggrieved. The little medical fairy was silent for three seconds. "... Shut up and return the candied haws to me." (The plot and characters are from novels/comics)
