Everyone claims to be loyal, but ask them to enlist, and nobody goes!

Well, now the Emperor's blessing has fallen upon Sith, our fragile, overworked wage slave from the 21st century: the God-Emperor has conscripted him into a local PDF (Planetary Defence Force).

Fortunately, our protagonist awakens a system. As long as Sith personally participates, whatever he does earns him a hundredfold positive return.

He thought the system was nothing special, only to discover that this damn thing actually works on concepts!

So when Sith leads his soldiers into battle, fighting once counts as fighting a hundred battles, and fighting a hundred battles counts as fighting ten thousand.

After a single Apocalypse battle, he immediately gains an entire army of hundred-battle Apocalypse veterans, with all kinds of conceptual hundredfold multipliers cropping up one after another.

Eventually, not only are the God-Emperor and the four Chaos Gods fighting over him, but even Gork and Mork insist that our protagonist is their most Waaagh! boy. They demand that Sith lead the Orks, now renamed the 'Xisi Boyz,' on a Waaagh! across the entire galaxy.

But as Sith fights his way across this fucked-up galaxy, bearing the blessings of the seven gods' chosen champion, years pass before he suddenly realizes something about his hundredfold positive returns...

How the hell did they turn the four Chaos Gods good, too???
