Time for War: The RTS system

His life was cut short by a knife to the gut. Yet the world decided to toss him a bone, and choose him for one in a million opportunity—he will be revived, with a System.

Yet the god that had granted the boy's wish decides to test his intelligence by giving him a chance to customize his system. In the end, he made a rather unconventional choice: an RTS system, abilities to essentially create an army out of a thin air.

With formidable forces at his beck and call, his journey across the worlds in the multiverse has just begun, but which worlds will he aid and which will he destroy? Like heck if he knows, but this will be a fun ride.
