Synopsis 1:
After transmigrating, Li Yun awakens the Hand of Replication, allowing him to copy and enhance others' abilities. Unfortunately, his bad luck only lets him replicate a low-level ability.
Unexpectedly, during an exam, he encounters a young female examiner who turns out to be a top-tier SSS-ranked talent!
[SSS-ranked talent, Ice Age, successfully replicated! Reached max level, cannot evolve further!]
From that day onward—
[D-ranked talent, Seeker of Mysteries, successfully replicated, evolved to S-ranked Voice of All Things!]
[C-ranked talent, Presence Reduction Technique, successfully replicated, evolved to A-ranked Stealth!]
As abilities gather one after another, the gods descend to the world to destroy humanity. But he reaches out and touches the divine fetus filled with divinity...
Replication initiated!
In an instant, the aura belonging to the gods manifests on his body!
Step by step, ascending to the heavens! The God of the Mortal World!
"Hey, hey, I just have a few more abilities, why is everyone calling me a god?"
"From now on, the sky is your domain, and the mortal world is mine!"
