[Alias of this book: I just want to be a salted fish, but they insist on taking me to dominate the world]
Lu Che traveled through time and inherited a border territory full of pits. The walls are broken down, the treasury is empty, and the debt is full. I wanted to wait for death by relying on the system and become a rich man, but in the end - the female knight I rescued by chance insisted on helping him train the first legion of the mainland; the elf girl he picked up accidentally filled up the technology tree of the territory; the holy lady who took her in turned this place into the center of faith for all mankind.
Lu Che: "I really just want to build roads and build houses!" The monarchs of various countries: "Shut up! Your floating fortress is parked above our heads, and you still say you only want to build houses?"
This is actually a heart-warming story about an infrastructure maniac, leading a group of confidante with special skills, to build the ruined border into a "forbidden zone for the gods". (The introduction is weak, please read the text, you won't lose money by investing!)
