Traveler Around the World

In 2219 AD, I worked for a super military-industrial company in the second alien world where humans descended. My daily job is to control the spiritual machines in another world on earth to fight against Asuras. This world is called the ring world, which consists of a space-time rift and the habitable planets parasitized by it. I heard people say that as long as we capture this world with intelligent beings, our war with Asuras will end forever.
