I Opened a Cram School for the Prince, and the Whole World Was Shocked

Jiang Qinian inherited a dilapidated academy and was accidentally bound to the "Ten Thousand Worlds Canopy System". At the beginning, you receive a hell-level mission: save the "difficult" princes who died in the most miserable circumstances in history, and drag them to cram school in modern times! As a result, the young master Fusu, who was about to draw his sword and kill himself, the Ming prince Zhu Biao who was seriously ill and dying, and the deposed Han prince Liu Ju who committed suicide in despair, all became "high school repeaters" in the academy. Jiang Qinian not only taught them mathematics, physics, chemistry, and world history, but also took them to experience modern life and prepare for the college entrance examination. And every move they make in modern times is broadcast live to all worlds and dynasties by the sky screen around the clock! In the time and space of the Qin Dynasty, the first emperor Ying Zheng saw Fusu with "Three Years and Five Years of College Entrance Examination Simulation" written on the sky screen, as well as the historical spoiler of the death of the Second Emperor of Qin Dynasty. He was so angry that he drew his sword and angrily killed Zhao Gao! During the Ming Dynasty, Zhu Yuanzhang watched his great son who should have died of illness thrive under modern medicine, and even learned to build a steam engine. While he was crying, he hung Zhu Di up and beat him! In the time and space of the Han Dynasty, Emperor Wu of the Han Dynasty looked at Liu Ju who was eating hybrid rice and angrily scolding himself for being militaristic. He cried bitterly on the spot and issued an edict to punish himself! When the tutoring ended and the princes, who had been thoroughly baptized by modern civilization, returned to the dynasty with world maps, hybrid rice, and modern firearms, the whole history went completely crazy!
