In the heart of the Dark Domain, Lu Yin watched An Jiu and the others use their battle skills with his domain, hoping to find a clue connecting this place to Primeval Space.
Reverse Step alone wasn't enough to determine the exact connection between this space-time and Primeval Space.
Ancestor Chen hadn't been the first person in Primeval Space to master Reverse Step. He had learned it from someone else, too.
Every space-time had its own unique qualities. Darkness Space-Time was no weaker than the others. It had produced plenty of Battle Skill Cultivation Methods, all connected to its darkness.
That darkness was a kind of power, similar to star energy. Lu Yin could cultivate it too, if he wanted.
As he pondered this, he failed to notice the darkness of the Dark Domain growing deeper as An Jiu used his cultivation method.
It had already been too dark to see clearly—darker than the starry sky. Now it grew darker still.
An Jiu kept his breathing steady, concealing his agitation. He was indeed using a cultivation method, but it had only one purpose—to awaken the ancestor.
Darkness Space-Time had an Extreme Expert: an ancestor who had lived for an unknown number of years. Reverse Step hadn't come from the Darkness Tome, either. It had come from that ancestor.
Only the ancestor could deal with this man.
The ancestral precepts stated that any outsider who threatened Darkness Space-Time was to be killed without exception, regardless of their identity.
That was why the Shadow People had attacked both the Eternal Clan and the Six Directions Meeting: they were following the ancestor's instructions.
Lu Yin hadn't noticed anything. He knew little about the Shadow People, and even the Lost Race, who knew Darkness Space-Time better than anyone, couldn't have known every Battle Skill
