Super Mechanic: God of Superpowers!

This book is a fanfiction of the game "Super God Mechanic," but it can be read smoothly even if you haven't read the original work.
Under the influence of a mysterious force from the East, Ye Xiu transmigrates to the world of "Starry Sea" and becomes a test subject at the Valkyrie Experiment Base. He is brainwashed right from the start, and in a critical moment, he unexpectedly awakens an S-class superpower—Replication.
The body of the God of War stands eternally in the starry sky, neutron light waves destroy the heavens and the earth, and carbon elements control a wide range of precise slaughter of life forms.
I, Ye Xiu, am the supreme god of supernatural abilities in the Star Sea World.
If it weren't for the players, this book would be a serious and proper transmigration story...
As NPCs, normal NPCs offer a full range of functions to players... issuing quests? Adjusting affinity? Teaching skills?
