My Arch-Enemy Brother and I Had a Fight.

Jiang Zhichu, as a junior sister of the Xingyan Sect, will have to fight to the death with her fellow disciples on the day when her skills are perfected. The winner will inherit the sect's ten thousand people, while the loser's Huang Shabai Bones will be unknown. She and her senior brother Xi Yu were born to be rivals, and they would never let go until they died. The senior brother is extremely talented and can frost fourteen states with one sword. Everyone says that the winner will be him. She didn't believe it, so she practiced hard for many years, just so that she could beat her senior brother in a life-and-death fight. But... Senior brother seems not to have this ambition, and is not afraid of life and death. He would teach her generously when she didn't understand, would teach her moves when she was practicing swordsmanship, would stand up for her when others bullied her, would show mercy every time when he had the chance to kill her, and would rub her little head to encourage her. "If you don't kill me, aren't you afraid that I will kill you in the future?" She wondered. Xi Yu just smiled lightly and said, "Wait until you can defeat me, and then think about this again." Later, she won him over. Someone had tampered with her during the life-and-death duel, and her sword went into her senior brother's chest. She heard others calling her despicable, and she saw her senior brother's shocked eyes. The white clothes were stained with blood, and the figure fell like snow, falling to the ground with a crash, followed by cold tears. She personally killed her senior brother who had loved and protected her for more than ten years. She always felt that Xi Yu was her mortal enemy, but she didn't understand why she cried so sadly while holding him covered in blood. In his arms was a birthday gift that he wanted to give to her. The clear words were stained with blood, and it read - I wish my junior sister peace, joy, and eternal peace of mind. * Jiang Zhichu became the leader of the Xingyan Sect and went to the Immortal Realm to congratulate the Immortal Realm Prince on his return from the tribulation. Among the crowd, she caught a glimpse of the prince's face, which was no different from Xi Yu's. He stood erect, with a jade face and an immortal posture. His peerless demeanor was unparalleled in the world. But Xi Yu was cold and distant to her, and didn't remember her at all. Hearing that he encountered something bad that he didn't want to remember during his tribulation, he had already lost the memories of more than ten years in the mortal world. Jiang Zhizhi knew that he hated her, so it would be fine if he had forgotten her now, and she would no longer provoke him. However, not long after, a marriage contract was sent to Xingyan Sect. "If the sect master marries me, I will protect you throughout your life. If you don't marry me, I will destroy the Xingyan Sect that you cherish." Good news, Xi Yu remembered her again. Bad news, Xi Yu seems to have turned dark. * Jiang Zhichu was sleeping soundly. Xi Yu played with her silky black hair and stared at her beautiful face with a gloomy expression. Seeing her waking up in a daze, he held her chin and kissed her lips hard again, his lips and teeth grinding together, and the clear tears she shed were on his fingertips. This is his bride, the junior sister he has been thinking about for more than ten years. Even if she wanted to kill him and she didn't love him, he would do anything to keep her prisoner by his side and make her belong to him alone. He was longing for a love that had been destroyed by her own hands. Intention: Be brave enough to be yourself
