The protagonist transmigrates to the Ming Dynasty and becomes a prince of low status, ruling over a poor and barren territory. With an infrastructure-building System, he turns construction achievements into points that can be exchanged for technological blueprints and talented recruits. But the old nobility, whose interests are threatened, obstructs his efforts to introduce new policies and develop his territory at every turn. The System issues a time-limited quest requiring him to build a powerful army in a short time to repel foreign enemies. The protagonist faces a difficult choice: sacrifice some of his people’s interests to rapidly develop the local economy, or uphold his commitment to treating them well and pursue steady progress. Meanwhile, dwindling resources limit development, and conflict with the old nobles forces him to choose between the old order and new growth. The nobles also spread rumors and slander him, causing the people to misunderstand him. Although the protagonist defeats the old nobility each time, every victory comes at the cost of his people’s lives. With foreign invaders on the doorstep, he must strengthen the territory’s military forces within a limited time, but betrayal and manipulation by the old nobles also leave him facing a crisis of trust. Through practical thinking and reason, however, he gradually overcomes each obstacle, leads his territory to prosperity, and ultimately breaks the old order to become a great ruler.
