I Am Immortal in the Universe

[Invincible, immortal, and undying] The protagonist is a god. He travels through various multiverses and the Myriad Worlds. He is weak at first, but gradually gains control over the authority of a god.

In this vast, boundless universe, he floated like a forgotten speck of dust. Endless darkness wrapped tightly around him, and every inch of space seemed to

crush him mercilessly, suffocating him. He spread his arms, but there was no warmth to embrace, only the cold stillness of death. Time lost all meaning, and death became a longed-for release. Trapped in this eternal cage, loneliness gnawed at him as despair surged like a tide, wave after wave, never ceasing. All he could do was endure the torment of immortality in this endless void until the universe came to an end.
