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 fact, after entering the room, Tang Ling noticed the huge machine because other than that, there was nothing else in the room except for another messy bed.

So, it was easy to guess that the second exam had something to do with the machine.

What kind of machine is this? Tang Ling frowned, not having any words to describe it.

It looked nothing like the machines left behind by the old civilization and was different from the machine that Su Yao brought him to test his strength with. Instead, it looked very advanced. It was perfectly constructed, forming an irregular rectangle, under which was a hole big enough for a person to enter.

Above the body of the machine was a transparent item that looked nothing like glass or crystal. It was more transparent than glass and more textured than crystal.
