At the Beginning of the Ming Dynasty, the Refugees Awakened and the Technology Tree Swept the Great Powers.

In the first year of Chongzhen, there was a severe drought in Shaanxi, and people died of hunger everywhere. Lin Feng, a doctor from Modern Science and Technology, traveled through the refugees as a soul and awakened the "Ming Dynasty Technology Tree System".

In the face of corrupt officials and Chongzhen's suppression, he was decisive in killing and promoting benevolent government. He recruited the medical woman Bai Susu to treat smallpox, and hired the peasant woman Zhao Waner to promote agriculture and mulberry, and gradually strengthened his power. Continuous technological breakthroughs - flintlock muskets swept the official army, hydraulic forging machines mass-produced armor, and improved Hongyi cannons defeated Chongzhen's third suppression, and finally won the title of "Governor of Shaanxi".

Lin Feng's sword points across the world, the musketeers conquer Junggar in the Western Region, the navy threatens the Mughal Empire to seize spices, the steam warships blast open the Istanbul Strait, and the Black Sea trade route is within its grasp. Under the double face of a tyrant and a benevolent king, a technological empire spanning Asia and Europe is rising - and Chongzhen's dragon throne is already crumbling...
