The pacing is slow. Before Chapter 34, the story focuses on building up resources and can feel a bit pointless. Feel free to skip ahead to Chapter 34 if it's not for you.
[Transmigration + Age of Empires + technological development + divine dragon] Fan Ritian unexpectedly transmigrates to the Three Kingdoms era, where time and space are in disarray. The lords contend for supremacy, Three Kingdoms characters appear in full force, and heroes from every era join the struggle. Starting out alone in the mountains, Fan Ritian gathers funds and recruits troops, mines the mountains for ore, secures provisions, forges weapons, researches technology, raises a divine dragon, and unifies the country. But his sights are set on the whole world.
