Outside the Sequence: I Build a Heroic City in the Demonic Realm

The demonic realm invaded, and the Qingxu human race trapped the settlement. Lu Kuan traveled through time and became a military student. He had just made a name for himself in the academy, but he was knocked down due to a trial that should have made history in the school - the casualties were too tragic. Dropouts from school, high pension debts, and eviction orders from settlements followed. But if he leaves the settlement, he will surely die. Fortunately, there is a pair of strange rulers: the Heavenly Ruler can measure the enemy and ourselves and transform demonic elements; the Good Fortune Ruler can communicate with mysterious "masters". It's just difficult to resolve the current crisis. In order to pay off his debts and survive, he started as a coolie and started a business route: "It's not that I want to make money, but I just don't want to see the folks eat poorly!" Seize resources, gather refugees, support people with business, and support war with war. Cultivation, fighting demons, clearing wasteland, building forts: "Fight across the south bank of Fallen Sky River! Plant flags and build a city!"
