The Tyrant Found a Princess at the Graveyard

In her past life, Tang Ruyi disguised herself as a man to fight on the battlefield for her brother, Tang Mu, earning countless victories. She was eventually stabbed by her own brother and died heroically. Reborn, Tang Ruyi vows to live for herself and sever all ties with her brother. Shockingly, her brother has also been reborn and abandons infant Ruyi at the graveyard. In this desperate situation, Ruyi is saved by Crown Prince Xue Shao, who is five years old. Xue Shao is temperamentally wild and violent, yet he treats his adopted sister with special favor and spoils her endlessly. He names her Xue Yu, hires experts to teach her strategy and martial arts, and employs a toxic healer to treat her and strengthen her body, helping her secretly restore her combat abilities from her past life.
