Underworld Sky: Records of Emperors of All Realms

In the underworld, the "Place of Rebirth" outside the Yama Hall suddenly glowed with golden light, and a hundred thousand ghost monuments floated in the air, reflecting the phantom of the "Ten Thousand Realms Sky Curtain". The King of Hell appears with the ten palaces of Yama, declaring the will of heaven, and will reveal the six core rankings from the Three Sovereigns and Five Emperors to the late Qing Dynasty: the list of emperors (ten best/worst each), the list of treacherous ministers, the list of generals, the list of scholars, the list of the army, and the list of princes. The souls of all the emperors who once ruled the world were recalled and formed into "camps" according to dynasties (such as pre-Qin, Han, Tang, Song, Ming, Qing, etc.). They sat on the ground and witnessed the merits and demerits of themselves and their descendants - but they knew nothing about "things of future generations". Every scene revealed would spark controversy and lamentation spanning thousands of years.
