I Returned to the Top of All Realms. So What If I Kill Without Mercy?

[The tags are wrong: no romance, strong female lead, ensemble cast later on, imperfect heroine]

Chu Jingchen, the pride of the Chu family in the north, falls from the heights of glory in a single day, only for an even greater conspiracy to emerge.

It turns out the strongest beings in this world aren't from the Western fantasy realm, but are the gods of Huaxia.

With the arts of Huaxia fractured and forgotten, Chu Jingchen returns alongside the ancient gods and culture of Huaxia.

On her journey to seek revenge, she explores secret realms and encounters the heroes of old.

After the genius tournament, an even greater threat emerges, and the geniuses of every nation join forces to fight the foreign enemy.
