My Name Is Huang Tian, What the Hell Does 'The Blue Sky Is Dead' Mean?

"Doctor, for the past ten days, whenever I'm falling asleep, I keep hearing someone calling my name in a daze." "Mr. Huang Tian, that's an auditory hallucination." "I'm certain I heard it." "Then it's somatic anxiety." "Somatic anxiety?" "In short, there's nothing wrong with you. Don't worry. Cut out smoking and drinking, maintain a regular sleep schedule, relax your mind, and you'll get better." "..." September 5: I went to see a doctor. The doctor said nothing was wrong with me, and I felt a bit relieved—only to get laid off by my company that very afternoon. September 6: I tried not to think about anything before going to bed, and surprisingly slept straight through until morning. Yet the moment I opened my eyes, to my horror, I heard someone calling me. That was the first time I heard the voices while fully awake. September 7: I went without sleep the entire day, looking haggard, because day and night, phantom-like whispers kept echoing in my ears. September 8: I was overjoyed to discover that not only could I tune out the voices calling to me, but I could also trace the sound to view the scene of the people talking about me—could I be a god? September 9... Sometime later, just when I thought my power ended there, the distant roar of tens of thousands chanting in unison echoed in my ears: "The Blue Sky is dead, the Yellow Sky shall rise!" I was dumbfounded: Wait, that Huang Tian is me, too?!
