Lu Qingze, a people’s teacher, once transmigrated into a book and became an unfortunate imperial teacher.

Surrounded by wolves, either defect to the prime minister who has power over the government, or cultivate the young emperor into a generation of emperors through the ages.

Out of professional habit, Lu Qingze chose the latter.

No one is in awe of Lu Qingze, the emperor’s teacher who raised the young emperor with one hand. He has countless supporters of the imperial teacher.
