The Escort Journey

The dragon slayer eventually becomes the dragon.

Everyone gets a bad ending, so read without fear. Choose between two endings.

Humans and demons belong to different worlds, and the realm is divided into three: the Northern Cold Demon Domain, the Central Plains Human Realm, and the Southern Continent Sea Realm. The Northern Cold Demon Domain and the Southern Continent Sea Realm both belong to the demons, while the Human Realm secures peace and stability by paying tribute year after year.

The heroine, Wu Bei, is attacked while escorting a convoy. To find her missing senior brother, she sets off alone for the Northern Cold Demon Domain. There, she uncovers the truth behind his death and gets caught up in a war between demon factions. After avenging her brother, she finds herself relentlessly pursued by the upper echelons of the demon regime, who want her dead. With no other choice, Wu Bei takes up arms to fight for humanity.

She returns to the Human Realm, sparks a rebellion, and helps the new emperor ascend the throne, restoring the laws of the world. But after being betrayed, she flees south once more, gradually descending into demonic madness.

She slaughters every evil spirit under heaven, only to become one herself.

The heroine has no canon love interest. Pair her with whoever you like.
