Apocalypse Circular

In the Wasteland Era, four grand circular walls separates the world of humans from the Exotic Species, which people also refer to as the Apocalypse Circular. Lu Luo has unexpectedly arrived in this world and, feeling somewhat helpless amidst the sudden crisis, has seen this prompt in his vision: [You are so weak it's suffocating, Although you have awakened Grade S-02-Devourer and Grade S-04-Fusioner, it's actually pretty useless. The only thing that can truly help you escape this crisis and lead you to the pinnacle of life is Sequence S-11-Observer.] [The above evaluation comes from the noble Grade S Sequence-11: Observer's fair analysis.] Lu Luo: “? This evaluation, so fair huh!”
