Zhaoyu, the Demon Dynasty's Little Princess

Outer Devil Realm.

The air here was perennially steeped in gray-black devilish baleful qi. Even the sky looked gloomy and overcast. Only the radiance of the blood moon shrouded the land, casting everything between heaven and earth in an eerie, murderous glow.

At a strategically vital gorge mouth stood a pass.

This pass bordered the Red Crystal Salt-Alkali Land. The surrounding mountains, valleys, and earth all bore a faint red hue, hence its name: Red Gorge Pass.

Red Gorge Pass stood along one of the Outer Realm Devil Race's routes of advance.

Supply lines were even harder to establish. From a defensive standpoint, it could indeed be called a place that was easy to defend and hard to attack.

For countless years, Red Gorge Pass had firmly contained the Outer Realm Devil Race's advance.

Yet precisely because it was easy to defend and hard to attack, the Eastern Defense Zone had stationed only one battle regiment at Red Gorge Pass: the Eighth Battle Regiment of the Eastern Defense Zone Corps, Immortal Dynasty No. 3 Defense Base of the human race.

The Eighth Battle Regiment was not a main-force regiment. Its commander, Luo Yangyu, was an early-stage Divine Ability Realm cultivator. His five to six thousand troops were a standard regiment configuration, with the lowest-ranking soldiers being early-stage Spirit Platform Realm
