Lu Zhi was forcibly bound to a System, but her first mission failed because she refused to cooperate at all.
Before she left the mission world, the punishment mechanism extracted and separated the 'factors' in her soul that had caused the mission to fail.
After failing to resist the punishment, Lu Zhi lost part of her memory and 'successfully' became a tool person who met the System's requirements.
The above is the premise.
Take down the System within ten chapters, Lu Zhi
P.S. Fast-paced, with very little content in the quick transmigration worlds. The heroine's CP is herself, though you could also say there isn't one.
Theme: "At midnight, the Host comes to claim your life." "How is being with myself supposed to count as being in love?"
