Destiny Simulation, from a Dead Body to a Common Person for Eternity

As soon as Gu Yuan opened his eyes, he saw a magnificent world. One day, a ghost established a Taoist system and wanted to establish ten palaces of the underworld to control the reincarnation of all living beings. There is a demon lord who steps up to the sky and wants to create a world where everything is silent and only I am the supreme one. There is a swordsman who ascends to the sky, blows down three thousand stars with a breath of sword energy, and wants to be immortal like the sun and moon. In the five realms and four seas, in all the heavens and the universe, mythical geniuses have risen up one after another, wanting to compete for the supreme immortality. Fortunately, Gu Yuan had a scroll of fate with him. Simulate your destiny and live a wonderful life. Three thousand years ago, he was a guest in the human world, his chivalrous and thunderous spirit swept the world, and he became an immortal in the mortal world. Ten thousand years ago, he was the Patriarch of Demons, and he was the master of demons in the world, killing them until everyone in the world bowed down. Fifty thousand years ago, he was the most proud swordsman in the world. His sword power was the most respected in the world for a hundred thousand years, and he was respected as a god by swordsmen in the world. One hundred thousand years ago... When the years are blurred and mottled, they turn into myths and legends. Gu Yuan suddenly looked back and realized that he had suppressed this ancient world and was respected by the whole world.
