Liu Sanyuan, a graduate student from Qingbei, transmigrates to the Tang Dynasty during the Zhenguan era. He'd planned to become a carefree tycoon.

But after Li Shimin runs into him while he's opening a shop, Fang Xuanling drops his disguise and reveals his identity. With no choice, Liu Sanyuan is ordered to teach the princes.

His System awakens: he can earn rewards just by teaching the princes knowledge?

The Tang Dynasty's way of doing things is never the same again.

The Western Turks invade with their entire tribe? No problem.

Li Yin and Li Kuan: "Our city walls are made of reinforced concrete, 15 meters high and eight meters thick. Built entirely with industrial methods. Satisfaction guaranteed."

Technology is underdeveloped? No problem.

Li Tai: "Odd functions are odd, even functions are even; learn math, physics, and chemistry and you can go anywhere without fear."

Seated on his throne, Li Shimin looks at Crown Prince Li Chengqian standing below him.

"A five-year strategy! Moderate prosperity in ten! Within ten years, our Great Tang will dominate the Earth!"

And so, as the Tang Empire rises, Liu Sanyuan, the tutor to an entire generation of emperors, has become invincible in the world.

Li Shimin: "I asked you to teach the princes, and you turned them all into sages?"
