So why have I heard that you bought an entire street in the center of their city?”Luo Yan: “Foolish! Do you know nothing of strategic house-swapping? By purchasing their city, humans are forced to relocate to my underground city.”Succubus Reporter: “But… but I heard that when the humans found out even the Demon King bought property in the Holy City, instead of panicking, it doubled the real estate prices there.”Luo Yan, smugly: “This proves my plan is flawless!”Meanwhile, in the dungeon, mining skeletons (players) were shouting.“Developers, come out and face us!”“Where’s the promised legendary pets, gear, leveling, achievements, marketplace, junior sisters, senior sisters… the whole system?!”“Is this game really just about mining?!”                                                                                                                                                                                                Army Building                                                                                    Demon Lord                                                                                    Dungeon Master                                                                                    European Ambience                                                                                    Fantasy World                                                                                    Game Elements                                                                                    Gamers                                                                                    Male Protagonist                                                                                    Modern Knowledge                                                                                    Non-human Protagonist                                                                                    Strong to Stronger                                                                                    Succubus                                                                                    System Administrator                                                                                    Transmigration...
