Zhenguan Industrial Empire

Modern man Ye Feng traveled through the Zhenguan period, started his business with barbecue and snow salt, established a stock exchange and a military industrial group, and used capital and technology to leverage the national destiny of the Tang Dynasty. He first helped Li Shimin eradicate the princelings, then supported Li Zhi to ascend the throne, appointed himself regent, and promoted the industrial revolution, land reform and interstellar colonization. When the alien "Reaper" fleet approaches, Ye Feng uses "Magic Industry" to recreate the enemy ships and annihilate the powerful enemy in the orbit of Mars, upgrading the Tang Dynasty to an "eternal civilization" across the galaxy. In the end, he led the expedition to the extragalactic system, leaving behind an interstellar empire that was illuminated by the sun and the moon and was all Han territory.
