Rewrite Kagura's Fate in the City

Chen Xuan, a wealthy but mediocre college student, thought his life would be ordinary. One day, he obtains a system that asks him if he has any wishes. At first, he can't think of one until he sees a tragic character and remembers his wish: 'If possible, help me rewrite Kagura's ending; she shouldn't die like that!' The system fulfills his wish, but unexpectedly causes a dimensional rift. The virtual becomes reality, and the shocking changes in the other world, along with the Imperial Demon Jade born from the world's will, force Chen Xuan and Kagura into a new war spanning a thousand years.
