But when he opened his shop, he ran into Li Shimin and Fang Xuanling, who were traveling incognito and revealed their identities. With no choice, he was ordered to teach the princes.

The System awakened. As long as he taught the princes, he could earn System rewards?

And so, the Tang dynasty's entire way of life became impossible to salvage.

Li Yin and Li Kuan: "My city has reinforced concrete walls, 15 meters high and eight meters thick, built with pure industrial methods. Honest quality, no tricks."

Technology is underdeveloped? No problem.

Li Tai: "If the function's even, the change is odd; if the function's odd, the change is even. Learn math and science, and you can go anywhere without fear."

Li Shimin sat on the throne, looking at Crown Prince Li Chengqian standing below.

"A five-year strategy! Prosperity for all within ten years! In just ten years, our Tang Empire will dominate the Earth!"

And so, Liu Sanyuan, the great tutor of the age, became invincible as the Tang Empire rose to greatness.

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