The First Immortal of All Times

In ancient times, the Emperor of Heaven came into being, swept away the demon clan's dominance over the world, created a kingdom of all nations, and made all living beings in the world qualified for cultivation. Time flies, even the supreme glory of the Heavenly Emperor cannot withstand the passage of time. The last Heavenly Emperor finally embodies himself in his own hall. From then on, no one in the world could take charge of the overall situation. All races were ready to take action, and the situation in the world was confusing for a while. A voice came from somewhere. When the Emperor of Heaven emerged, he left behind his own inheritance. All races tried to fight for it, but no one could open the door of the Emperor of Heaven's palace. Thousands of years have passed in a hurry, and all sentient beings no longer think about the inheritance of the Emperor of Heaven, but begin to make plans for themselves, in order to become the next Emperor of Heaven. But at this time, there are alien beings who want to parasitize this world, and want to become the emperor through the power of this world. The two parties fought fiercely, but how could the world without the Emperor of Heaven be able to withstand them? They were retreating steadily, and in the end they could only shrink into the world and compete with the Emperor of Heaven's magic circle. Under such pressure, geniuses continued to emerge in the world, and with the protection of the Emperor of Heaven, the world ushered in a golden age. After tens of thousands of years, great emperors continued to appear, but no one could open the door to the Heavenly Emperor. And these great emperors disappeared after becoming great emperors. And the creatures outside the territory did not launch an attack. Things outside the territory were gradually forgotten by all living beings, but is this really the case?
