When the demons slaughtered the sect

Rebirth brought me back to the day when the demon clan besieged our community. In my previous life, my brother abandoned his pregnant wife to spend a romantic day with his beloved, leading to her tragic death while protecting me. I forced him to return, leaving his beloved behind. The demon clan was destroyed, his beloved met a miserable end, and my brother shattered my inner strength, severing my limbs. This time, I had his wife hand him a divorce letter with finality.
