Li Zhi, a genius from the twenty-first century, transmigrates to the Tang Dynasty during the Zhenguan era.
And somehow, he becomes the most useless crown prince in history?
Fortunately, his knowledge from his previous life is vast as the sea. In this era, Li Zhi uses it to crush his opponents with an overwhelming advantage.
He uses convex lenses to set the Turkic army ablaze, hybrid rice to end a century of famine, and the equal-field system to narrow the gap between rich and poor...
With a song of Chu, he single-handedly wipes out the rebellious army of the former Sui Dynasty.
With an ambush on all sides, he rescues a hundred thousand Tang cavalrymen from encirclement.
With the blood of our enemies, we honor the Zhenguan era of the Great Tang!
Divine-level Crown Prince Li Zhi, at your service!
