Invincible at the Start, Building an Eternal Giant City

'''[Invincible + Faction Building + System + Single Heroine] Lu Daosheng transmigrated into a cultivation world. After struggling for years, he finally climbed to the position of city lord, thinking his life would just be like this from now on. Until one day, the system arrived. Wait, this system feels a bit different. "System, are all the items in the shop free?" "They're free." "System, don’t I need to cultivate?" "No need." "System, I want a wife." "I’ll find one for you." And just like that, Lu Daosheng used his invincible cultivation and endless resources to turn his city into an existence that made the entire myriad realms tremble.'''
