I Went from Being Starved to Death to Becoming an Emperor

People's hearts value doing good will be rewarded and doing evil will be punished. The system only gives knowledge but not physical objects - so it forces the protagonist to create his own.

This book thoroughly explains "what is organizational power". The protagonist does not practice magical skills or rely on the system to send troops directly. He relies on queues, logistics, surveying and mapping, and intelligence - the modern military system's dimensionality reduction attack on the cold weapon era. See how he can train a group of starved soldiers into an iron army, and how he can leverage a dynasty with a piece of land book. The cold and restrained line drawing style, the brotherhood is written too harshly, the chapter of Black Rock Gorge is recommended to prepare tissues.
