Reaper's Resurgence: A System Reset

What would happen in a world governed by the Ascendants, the highest level people in the System, when the System itself resets due to the death of its creator? When the levels, classes, skills, and even Legendary Feats of every user are wiped, and everyone is sent to a new dimension to start all over again? Alexia, on what should've just been her very first Dungeon dive in the Royal Dungeon, finds her life, her body, and her entire world changing after the Creator of the System itself forces her to kill him, resetting the System entirely. But after being turned into a quantum reaper and given the powerful quantum element as a prize' for her Legendary Feat, will she thrive? Or will she fall? What to expect: Quantum Magic using Main Protagonist, Anti-Hero Protagonist, System Reset, Polearm using Protagonist in terms of their weapon, and LitRPG. What not to expect: Magic to follow science and reality based on quantum mechanics. There will be some skills that will have some relation to quantum mechanics in the much later books of the story, but definitely not at the start, and not too deeply related. Do not expect magic to follow laws of science. The world that the main character is in prior to the Reset is not a modern world. It is more similar to a fantasy world with swords and sorcery in terms of the morals and ethics of the people just with modern technology. Furthermore, Alexia is twenty years old. Furthermore, the vast majority of the reviews are out of date due to me editing the story as it goes on.
