After Dressing up as Princess Chongxi, She Just Wants to Be a Salted Fish

She is the only military doctor with a medical system, and he is the invincible regent. Once she traveled through time, she became the bastard legitimate daughter of the Hou family whose mother died and was not favored. Her engagement to the prince was annulled on the day of her wedding, and she was given to the regent Chongxi who was seriously injured on the battlefield and was dying. In order to survive and not to be a widow, Hua Zhixi was either rescuing people or on the road to rescuing them. "A certain prince, can you please stop for two days occasionally? I just want to be a legitimate salted fish!" "Princess, there is ambiguity in what you said. I will teach you how to say it..." Bastard, can someone tell me where this crooked regent came from? "The princess saved my life, and I have nothing to repay. I can only promise to protect her with my life, and I will always love her!"
