The End of the Eastern Han Dynasty: I Use Codes to Deduce the World

At the end of the Eastern Han Dynasty, the world was in chaos. Chen Xuan, a modern programmer, traveled through time and became the son of a down-and-out nobleman. He awakened the power of the "Spiritual Pivot" and could deduce battle situations, farm and steel-making, and spread forces like a game. He originally wanted to develop in a low profile, but he rescued Ji Zhao, the exiled princess of the Han Dynasty. The woman was yandere and paranoid, and decided that he was her only destination. The princes are divided and power schemes are everywhere. He pretends to be a pig and eats the tiger, plays chess behind the scenes, and uses his wisdom to break the situation. Anyone who hurts his relatives will be destroyed. A madman who protects his shortcomings and a crazy beauty, turns his hand into a cloud and controls the mountains and rivers.
