I Fused with the Calamity of Time and Disguised Myself as Yang Jian

[Urban high martial arts] + [Devouring evolution] + [Undercover] + [Calamities] + [Decisive and ruthless] + [Plot-driven]

(Not a traditional calamity story. The protagonist is like a ghost wielder, with a calamity inside his body whose power he can use. He will merge with more calamities later. His time powers are somewhat weak at first, since time abilities are too powerful for him to fully wield when he is still weak. He'll grow stronger as the story progresses.)

Transmigrate only to be grabbed by the throat by a monster?

In a desperate situation, Lu Yuan is forced to merge with the top-tier, high-dimensional calamity known as the “Eye of Time”!

He gains the immense power to control time and must continually devour calamities to resist the calamity of time.

But merging with calamities means becoming a “Fallen,” relentlessly hunted by humanity's Sacred Purge Court.

What's there to panic about? Lu Yuan pulls off an incredible maneuver, using the Eye of Time's unique traits to disguise himself as the sequence “Yang Jian's Heavenly Eye”!

An official squad shows up in the middle of the night to interrogate him?

He simply uses time reversal to test every possibility, exploiting a perfect bug to pass the death test!

In public, he is a brilliant, aloof prodigy at the Human Defense Academy, admired by all!

In secret, he is a peerless demon prowling the night, hunting every calamity and formidable foe, devouring everything in sight!

Backstabbing at the limit, devouring evolution, dimensional suppression! Lu Yuan uses his time powers to carve out a path to godhood between calamities and humanity!

When countless calamities descend and the Abyssal Monarchs attempt to purge Earth, he stands atop a mountain of corpses and a sea of blood, opening the Eye of Time, its icy blue markings spinning...

“I'm afraid I'll have to help myself to your time!”
