June 15 of the year 2010, the third awakening happened. Several smaller worlds had returned to connect with the main world as living beings of different races started to appear and some people managed to connect with the origin and gain control of various powers: control of fire, of water, of wind, of air, and of earth... In the midst of all these confusions, towers that gave unimaginable powers began to appear in all corners of the world, where those who already had powers could upgrade and become more powerful or even those who did not have powers could receive powers through tests of the tower. And because of these towers, conflicts started to happen in all corners of the world by those wanting to monopolize these towers.

However, in his final moments before being killed, he was transported back to four months before the third awakening that started the apocalypse on earth. Being a man who lived for a thousand years and had accumulated several techniques, he now had a new chance to correct some of his early mistakes. Luan decided to make the most of this new chance that the heavens had given to him.
