Being a Godfather in an Alien World

In this resource-scarce world where mechas run rampant, I chose to be a soldier in order to have enough food. Unexpectedly, I accidentally ended up on the main battlefield of the planet Motar and became a wandering mercenary. I was tortured by the two worlds of ice and fire every day with the activation of alien blood. I shuttled back and forth between humans and aliens, and it was always me who succeeded in destroying every conspiracy. It turned out that my background was very scary, and I became a big boss in the eyes of others for no reason.
