I Rely on Infrastructure to Counterattack the Tyrant

In the Jiuxiao Continent, the spiritual energy is exhausted and monsters are rampant. The once glorious Xuanhuang Dynasty collapsed, the princes were divided, and the people were in dire straits. In the ruins of Shiliang City, a city-defending warrior quietly awakened, and memories of his past life emerged - he was an ancient counselor and reincarnated as an NPC. The city is dilapidated and resources are scarce. The tyrant in the north massacres the city and plunders the land, leaving the people in dire straits. I accidentally got a golden finger, which can be used to deduce infrastructure, purify source crystals, and revive formations. It can rebuild city defenses, refine weapons, grow grain and water supply, and even build chariots and crossbows. While others struggled to survive, he built a city and established a country, the refugees returned, and the ruined city gradually prospered. When the princes are fighting in a melee, he has secretly laid an iron net; when the tyrant is suppressing the situation, he uses the weak to defeat the strong. In the end, we will gather the power of all the people to break the shackles of imperial power, establish the common master of nine continents, and usher in a prosperous era.
