Eternal Night Is Reborn, and Then Becomes Its Own White Moonlight

(Transformation + 1v1 + female protagonist's perspective + apocalyptic powers + academy group portrait) In 2148 AD, the tide of eternal night has engulfed most areas of the earth. Human beings rely on the glow of the World Tree to live in isolated cities. Young Long Yike died in battle in the eternal night of the future. When he woke up again, he went back to the past and became Lu Qinghe, a thin girl of unknown origin. There are various signs that there is still another boy named Long Yike in the world. Therefore, Lu Qinghe made it his goal to change the future of Lindu City's destruction and save his past self. But it wasn't until she embarked on the journey that Lu Qinghe realized that the secrets of this new body were far beyond her imagination. With abilities awakened in advance, a physique that cannot be contaminated, a world line that is off the established track, and blood with a strange fragrance, she is regarded as a savior by those who trust her, and as an alien by those who fear her... Her road to redemption will be full of unknown variables.
