Fantasy: I Go Back Millions of Years Since the Fall of the Emperor!

My name is Su Changge. I traveled to the fantasy world, practiced to the realm of the great emperor, and was devoured by countless supreme beings. When I woke up again, I returned to the Emperor's Fall era millions of years ago. My memory includes the details of everything that happened in the millions of years between now and the era of the fall of the Emperor. I vowed to kill those supreme beings who annihilated humanity. During the ancient times, I adopted an orphan girl, whom everyone in the era of the Emperor called Empress. In ancient times, I planted a weeping willow and taught her how to practice. During the Emperor's fall, she was called the Willow God. In the ancient times, I accepted a young man as my disciple. In the era of the emperor's fall, his name was Wu Shi. ... Millions of years have passed, the era of Emperor's Fall has been wiped out by my own hands, and the Supreme Forbidden City has been pacified by me.
