I, Yuanshi, Am Honghuang's Eldest Crown Prince

When Pangu split heaven and earth, the “One” that had escaped traversed the river of time and captured the consciousness of an ordinary person from a future age when magic had faded. It made him become Yuqing Yuanshi. To stop Hongjun, the remnant of the Chaos Demon Gods, from joining with the Heavenly Dao after proving his sainthood, wreaking havoc on the Primordial World through one calamity after another, erasing the imprint Pangu had left behind, and continually downgrading the entire universe until he could seize the fruits of the Heavenly Dao, Yuqing Yuanshi was born ahead of time. He took part in the Beast Calamity, seized the initiative, and began laying plans early. In the end, he defeated Hongjun and drove the Primordial World to a higher dimension, allowing the great Pangu to be resurrected and repaying the debt of karma.
