I, the Great Emperor in My Twilight Years! Crushing Forbidden Zones and Slaying the Supreme!

[Emperor] + [Feel-Good Power Fantasy] + [Dark Turmoil] + [Supreme Beings] My name is Shenyue You, and I transmigrated! From the start, I was the last Great Emperor in the Shrouding the Heavens world, enduring a hundred thousand years of lonely invincibility. But now my twilight years have arrived. My life force is fading, and my lifespan is nearly over. The ancient Supreme Beings within the forbidden life zones have awakened. They regard all creation as mere dogs and all living beings as food. A dark turmoil sweeping across the universe is about to begin. My descendants live beneath a bright and peaceful sky. How could I let the likes of you run rampant? Dragging my failing imperial body, I resolutely stepped into the forbidden zone. A bloody battle: imperial blood stained the starry river red! Just as I was about to breathe my last and my soul was about to perish... [Ding! Host is on the brink of death. The Desolate Heaven Emperor template has been activated!] In an instant, my white hair turned black, and my vitality returned to its peak! No! It had surpassed its peak! "He transforms into freedom, he transforms across the ages..." The moment I unleashed this forbidden imperial art that did not belong to this world, The Supreme Beings who had unleashed the turmoil went mad! "Impossible! This isn't a technique of this era!" "Who are you? Who are you really?!" I am Shenyue You. I am the Great Emperor of this era, and also... the Desolate Heaven Emperor!
