Transmigrating to the Cultivation World to Become a Sword Cultivator

Strong female lead, no CP, the heroine isn't a do-gooder and kills without hesitation. A killer transmigrates into another world. No male lead.

Lin Ji was a killer who died unexpectedly while carrying out a mission and transmigrated to the cultivation world. She embarked on a path of cultivation and became a sword cultivator. She repaired the original owner's soul, wiped out the Pei family, defeated the demon race, forged a divine sword, and ultimately achieved immortality.

Lin Ji's own body has one soul, not two.
