On the seventh day of the apocalypse, Gu Yuan was stabbed by his henchman and thrown into the sewer. He lay in the stinky ditch, watching the manhole cover above his head being welded shut, thinking that this time it was really over. Then a virtual panel popped up in front of him: Congratulations, you found the first upgradeable territory. Gu Yuan stared at the huge Level 1 on the panel and smiled. Welding manhole covers, right? When I reach level three, your nest will be the first to be demolished. What he didn't know was that he was not the only one who could see the panel in this apocalypse.
