Story:

The mentor of the Emperor of the Heavenly Kingdom was born again during his high school studies. Surprisingly, however, he found a dragon in his body too… Can you resist oppressive circumstances or will you give up when you are still very weak? In his past life, he obeyed, but in this life… the emperor's outstanding mentor now dominates the city, maybe with one palm he can collapse the heavens, but only one thought was spinning in his head: why did I, the great king, find myself among the people?
