The hero Gordon killed the Demon King and was finally able to return home. But he was reborn in 2009 and gained the ability to travel between different worlds.

He then discovered that by using the magic he obtained in another world, he could skip the complicated process and create the most powerful chip using only sand!

What crown jewel of human technology? I can simply replicate it infinitely!

What, the empire's strongest mage? Take this thermobaric bomb!

Farming in another world and getting rich in the real world – this is the right way for a hero to live!
