After Betraying the Demon Lord, She Dominated the Three Realms

Intro: When a person is down on their luck, even transmigration offers no benefits. Jane Lin, a domineering CEO, unexpectedly transmigrated into a minor cannon fodder character on the eve of her company's IPO. Facing immediate death, she was forced to bind herself to an unreliable system to survive. How unreliable was it? The system's missions involved betraying people, and her target was none other than the Demon Lord. Jane Lin's assessment: Wicked and life-threatening. The system's retort: Complete the missions, ascend to godhood, and you can return to your original world. Fine, she'd do it! Besides, the Demon Lord was a major villain. Betraying him was acting on behalf of heaven, so it wasn't entirely wicked, was it? Later events proved her worries were misplaced. The Demon Lord was cold, powerful, and indifferent to women. Gaining his affection points was harder than reaching the heavens. She danced in flowing veils, planning to intentionally fall into his arms, only for the Demon Lord to wait with a wolf-toothed club for her to crash into. When she was poisoned with an incurable ailment, she knelt and begged the Demon Lord for help, feigning pitifulness. He remained unmoved, kicking her into an icy pool to regain her senses alone. It wasn't until she accidentally fell face-first that the Demon Lord curved his lips, earning her one affection point. Jane Lin: ... A wicked system paired with a wicked villain. She had to overthrow this wicked world!
