Time Travel and Conquest of Westeros

My name is Gu Yuan, I am a modern person, but somehow my soul traveled to this world of Song of Ice and Fire. This is a cruel ancient fantasy world with constant wars. Fortunately, I have the golden finger of the Age of Empires game system, which allows me to summon military units and buildings. I want to build my own power, and Lucas has been following me loyally. I will continue to fight, expand my territory, obtain resources, and unlock system upgrades. My goal is to unify this continent. This novel and its characters are purely fictitious.
