A Demonic Cultivator, but Make It Jujutsu Kaisen

Jiang Li, a demonic cultivator hunted by the cultivation world, used the System to escape to the Jujutsu Kaisen world. Completing missions would earn her points to transmigrate to the next small world. But since Jiang Li had hijacked the System halfway through, she accidentally transmigrated to the Heian era, the age of Ryomen Sukuna. The System was low on energy, and with the dark age being the perfect time to gather resentment, Jiang Li stayed for a year to build up her strength. But the jujutsu world saw her as Sukuna’s ally, so Jiang Li was sealed too, and sent along to the Jujutsu Kaisen world a thousand years later. In the future, Geto Suguru contracts her as a cursed spirit, and she turns over every last tragic ending, healing the Jujutsu Kaisen main cast… No-couple female lead, parallel world with a focus on Gojo and Geto.
