In order to seize control of the Netherworld, Old Ancestor of the Underworld River and the Buddhist door erupted in a great battle.
Then, the first below the Saints, known for creating Asura, founding the Asura religion, and hailed as the immortal Underworld Ancestor of the River—I will not perish if the Underworld River does not—was sealed by two Saints of the Western religion, along with the Underworld River, utterly vanishing from the stage of Prehistoric World's history.
Without any surprise, without anyone's aid, Old Ancestor of the Underworld River would remain sealed, until the arrival of the Immeasurable Kalpa, perishing along with this world.
Therefore, Old Ancestor of the Underworld River was extremely eager for freedom; he did not want to perish with this world, he wanted to become a Daluo Jinxian of the Primordial, he wanted to transcend Heaven and Earth, unscathed by Neverending Calamity.
