The Heroine Takes the Role of a World-Restorer in an Alternate Northern and Southern Dynasties

In the final years of the Tang Dynasty, the realm descended into chaos. Armies rose on all sides, the earth shook, cold waves swept across the land, and crops failed. Bandits ran rampant, demons wreaked havoc, and spirits and ghosts bewitched the world as public resentment boiled over.

Carved railings and jade terraces turned to ash in the flames, then were swept into the sky by the gale. Below, the people had abandoned honor and dignity, struggling in pools of blood and fields of mud. As the lights of dreams and hope went out, lives and souls stumbled, one after another, into the boundless darkness. No one could protect you. No one could save you. This was the end of the world.

Sigh, weep, struggle, in this world hurtling toward collapse.

No. If all we do is weep and sigh, nothing will ever change. We must take up arms ourselves, defend what little remains, and reclaim everything we stand to lose.

P.S.:

1. The setting is the Northern and Southern Dynasties with low-to-mid-level magic, even more brutal and dark than history.

2. The protagonist will never lose her wits over romantic feelings, and neither will the other characters, unless they were already lacking in sense. Romance will not be the main driver of the plot.

3. The protagonist will grow stronger and stronger. She may be struggling just to survive at first, but later she will become the undisputed driving force and core of the story, as well as the strongest human fighter in the entire world.

4. Romance appears from time to time, but removing it would probably have no effect on the plot. The male lead's identity will not be revealed early on, so feel free to place your bets.

5. The female lead will not marry. She will become emperor, and she will not marry even after ascending the throne. If you want to read about a female lead who gets married, feel free to move along.

6. Although the title includes "Restorer of the World," the female lead's personality is not much like Aurelian's.
