Warhammer 40k: I Awaken the Warcraft System

[Natural disaster + mass production of troops + no female lead + decisive killing + four races of heroes + savior] As usual, young Fang Yun finished a game of Warcraft III, and the water cup next to him inexplicably spilled on the keyboard. A burst of lightning illuminated the dormitory, and Fang Yun regained consciousness.

"It's over! Five hundred worlds!"

It turns out that Fang Yun has arrived in the Warhammer 40k era.

So Tzeentch! Khorne! Nurgle! Slaanesh! And that false emperor sitting high on a golden toilet!

Let the Scourge send you on your way!!!
