After Rebirth, My Junior Sister Became a Monster Again

Before the sect competition, my junior sister fell in love with a mortal man while traveling in the human world. She brought him back to the sect and wanted to break the contract with me and practice spiritual life with a mortal. I warned her: "High-quality spiritual roots can only be found but not sought. Why would you let the turbid energy of mortals contaminate you?" As a result, on the day we became Taoist companions, she dug out my spiritual roots with her own hands and implanted them into the man for him to practice. She relived her life and returned to the day when she brought her man back. I did not hesitate to terminate the Taoist couple's contract and became the sect's law enforcer after severing my love.
