Qian Lingfeng, an avid Otaku, received the “Steel Shell System” by the choice of fate.
After he conquered the world, became a rich tyrant, met all kinds of beautiful women and opened a harem, and achieved the ultimate fantasy of thousands of Otakus, he suddenly realized that things seemed far from simple!

Where will the weak humans go in this world? Is there even a place left for them to get a foothold? Is humanity going to be extinct?
Or… can an Otaku save the fate of the human race?
