New author here, please show your support!!! The male lead is a master of keeping a low profile. He won’t reveal his System easily, instead quietly building up his strength. He may seem ordinary on the surface while secretly controlling resources behind the scenes. He’s patriotic, but not blindly so: when helping the country, he makes sure he stays safe and doesn’t trust others too easily. He might provide technology anonymously to avoid attracting attention.
The story may be divided into volumes. The first volume resolves internal conflicts in the courtyard and builds up resources; the second involves bigger enemies, such as spies, and struggles over technology; the third focuses on cooperation at the national level, with the male lead becoming a powerful figure behind the scenes. Each volume has different sign-in rewards to drive the plot forward.
