In the 23rd century, the earth's resources have been squandered by humans, and the upper class is frantically conducting space exploration in order to immigrate. A returning spacecraft was targeted by space creatures, and a large number of alien creatures secretly sneaked into it. After arriving on Earth, these aliens spread, parasitizing other living organisms. Since then, a large number of mutant creatures have appeared on the earth. Humanity has established an "anti-alien" agency and invested a large number of robots to eliminate aliens. The aircraft pilot Xiao Yuan died physically in an accident. Before dying, he downloaded his consciousness onto a nanochip and preserved it. Later, the company installed his chip into a work robot numbered BD09.

After fifteen years of working as a low-level social worker, he has now accumulated 99,514 points, and victory is waving to him not far away...
