High Martial: I Became the Final Witch and Married Myself

[High Martial] + [Gender Swap] + [Gender-Bender Romance (Self-Romance)] + [Genius Protagonist] Chen Xiyang was playing Galgame at home and was about to complete the Bad Ending route when a truck suddenly crashed into his bedroom and sent him off to another world. When she regained consciousness, she discovered she had transmigrated to a parallel Blue Star where calamities had arrived and people could awaken sequence-based abilities, though their bodies remained unchanged. She had been reborn as the game’s apocalyptic villain from the Bad Ending route: the Witch of the End. Unfortunately, the debuff that drove the Witch of the End to destroy the world came with her, turning her into a ticking time bomb who could lose control and end the world at any moment! Fortunately, the Chen Xiyang of this world had received the hero's status screen from the game thanks to her. As long as she stayed by his side, she could absorb his emotions through empathy to stabilize her mind and keep herself from losing control. To make “recharging” easier, she used her psychic powers to confuse this world's parents into adopting her. She became this world's Chen Xiyang's younger sister, and changed her name to Chen Xiyue. As she continued to recharge, Chen Xiyue's mind became more and more closely connected to this world's Chen Xiyang, until she gradually started to become just like him! By the time she finally realized what was happening, she was already too deeply involved to pull herself away.
