Core premise: The world's first virtual reality online game, Epoch, has launched, and it will determine how real-world resources are allocated. The protagonist gains the talent [Copy and Paste]: he can copy any skill from a player, NPC, or monster, including hidden and exclusive skills, and paste it onto himself or a teammate, with no cooldown or cost.
From the start, he copies the newbie village boss's skill and instantly wipes out the whole field. He copies rich players' top-up-exclusive divine skills, leaving them dumbfounded. One man becomes an all-around team.
Skills pasted onto teammates can be "revoked" at any time. He once assembled a legion full of "geniuses," then revoked their skills at the critical moment, wiping out the entire army.
Online-game stories are naturally fast-paced: the characters keep changing maps, encountering new monsters, and copying new skills.
