Stealing Pen: as an Evil Creature, I Sneaked into the Protagonist Group

[1V1+strong female character+black belly+villain's perspective+original plot] As the former Queen of Qingqiu who lived for tens of thousands of years, Bai Qiongyue was clean and clear even when she finally chose to die with the Blood Demon. Who knew that when she opened her eyes, she would become a girl from the Zhang family whose blood was about to be drained. The piece of cloth he handed over in the dark became the fetter that bound her for life. Bai Qiongyue: "You should stay with me from now on and be my real brother. I can help you get everything you want." Zhang Qiling: "... Okay." From then on, a fake sister who talked a lot about running things and a fake brother who was taciturn formed the most unreliable "plastic sister and brother" combination in history. She led him to regain the undercurrent of the Zhang family, eliminate the secretly infiltrated Wang family, suppress the turbulent southern border, and assassinate the Jiumen who stood by and watched. He followed her for fifty years, growing from a silent child to a silent man. She charges, he rears. She lays out the plan, and he closes it. She pointed at the map and asked where to hit next. He nodded, stood up, wiped the knife, and went out. He handed her tea when she cursed, and covered her with a blanket when she collapsed from exhaustion.
