My Inhuman Secret Identities Keep Multiplying [Dimensional Ascension]

[Long-form plot-driven story, male protagonist, no romance. Also known as End Times: His Secret Identities Keep Multiplying. Feel free to sample QVQ]

Synopsis:

What does a nonhuman being who comes to live among humans become? The answer, of course, is a nonhuman.

The End, the apocalyptic purifier who governs the demise of all things, descended upon the human world.

At first, Zhong Yan was just an utterly unremarkable human, diligently working for a government agency.

Later, each mission brought him another identity, whether he took it on willingly or not. Without exception, every one of them was nonhuman.

As a monster: [The Ever-Changing Nightmare, the Ancient Greenwood Tree, the Death Nether Serpent... until every law of the universe converged within him and he ascended to godhood, elevating the world to a higher dimension.]

As a human: [A Tamer of the Strange, the Dawn Star who saved the world...]

And in between: [From traitor who lured monsters to a holy servant of the gods, then eventually a double agent and the boss behind the scenes...]

The greatest evil god, the End, became the world's savior? Now that's a laugh.

World: Where did this onion come from? How did it save me when I was half dead? And how did it raise me to godhood?

The End: -_- It's me. What, don't want to live?

World: Aaaah! Help! Don't come near me, aaaaah!

Humanity sees him as a savior god who protects the world, unaware that he is the source of the disasters they fear.

And so, more and more honorific titles pile up.

Him: Stop adding more. There's really no room for that many people here, gods included.
