Upright? Main Character? Do You Look Like Me?

The male protagonist was reincarnated, but he didn't regain his memory... But it doesn't matter, this is an era of using the power of elements. As long as you obtain powerful power of elements, you can still dominate the world. Alas, the male protagonist has not awakened the power of elements... The male protagonist has no system, no memory of rebirth, no strong background, and is not a son of luck. His only advantage is that he can endure hardship. As the saying goes, as long as you are willing to endure hardship, there will be endless hardships.
