Help! I am bound to Aizen! - Chapter 303

[You have entered the dungeon at Gwachun Station’s 1st Exit.] When former high school student Kang Woojin finds himself returned back to Earth after being forcibly summoned to a foreign planet for 20 years, he soon finds that Earth is not the same, normal place as he once remembered it to be.

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 Tribe 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!
