After the Parricide Was Preached, I Found Out She Was My Sister

I practiced swordplay for 12 years just to kill one person - my "father-killing enemy" Li Yuqing. But the first time we fought, his sword missed my mark when it was thrust into my heart. I don't understand. Until I was seriously injured and on the verge of death, he used his only chance to save his life to save me, an enemy. What made me even more devastated was that the jade pendant I had worn close to my body for 20 years was actually the same pair as the piece he had lost. When my mother used her life to block the fatal sword for us and cried out the truth, I understood—— Half of my life's blood and hatred are all lies; the target of my sword is actually my father. What a jianghu bureau that hides the truth from the truth! From now on, the swords of my father and son will only collect debts from the real mastermind.
