When a glorious old civilization was toppled overnight, a strange purple moon rose and thus began the Purple Moon Era.
Damn it! What kind of ecosystem was this? The evolution was messy. Even rabbit bites and plants were not to be messed with. How can one survive all this? Evolve into a Purple Moon Warrior? What did this have to do with the Purple Moon?
What kind of map was this? The Safety Sector? The Floating Domain? The Darkness Port? The Storm Voyage? The True Capital?
The Horror Lullaby List? The resurrection of the Underground Race and the prospering Underground City? The Chaos Black Market that suffused the world? The Bloody Road?
More importantly, one could end up in a bloody slaughter when dreaming and enter the Dream Domain? Fine, this damned era! 

Dark Moon Era

In the Purple Moon era, information was definitely an unfair yet precious resource.

For example, those who were born into a group of Drifters and those born in a large safety city were totally different, at least, from how the world viewed them

The world in Tang Ling's eyes had once been a primitive land. It was filled with traces of an old civilization, yet he was unable to confirm whether it really existed or not. Places further away from the settlement were all a mystery to him.

On the contrary, Tang Long knew a lot of rules of the world ever since he could remember. He knew about the distribution of factions and the history of Purple Moon. Among the knowledge he had, he bore something deep in his mind, a number, or to be more exact, coordinates: Latitude 39.
