Rean crossed into another world. Without relying on cheats or systems, he spent over thirty years conquering an entire continent and establishing the first unified dynasty—the Holy Eldaria Empire. Just as he was about to achieve ultimate glory and ascend to godhood, he suddenly fell, his body withering overnight, leaving him less than a month to live. In order to cure himself, he entered the sacred artifact Source Cocoon, to purify the curse and rebuild his body. Ten years later, he was supposed to return in peak condition! But when he opened his eyes again, six hundred years had already passed. His empire had fractured, and the splintered nations were locked in endless wars. The age of magic was crumbling, and spellcasters once dismissed as mediocre had now become revered as masters. He himself had become a mere historical figure—and there were even rumors slandering him as a traitor. The good news: the curse was gone, and his body had indeed been remade. The bad news: it had been remade into that of a newborn. Worse still, the Source Cocoon carrying him had ended up in the hands of an elven girl—who now looked at him with sparkling eyes, insisting he call her “Mama”... After countless trials, he finally found his only surviving descendant—the empire’s last princess. “Hello, I am Emperor Shengyuan. I did not die. Now I need your help to rebuild the Holy Eldaria Empire. Once I reclaim my throne, I will name you the next queen!”

The world’s largest VRMMO, Conviction, was almost like a second world for humanity. It had integrated itself into the real world’s economy, with both corporations and individuals seeking their fortunes through the game.In this game, Nie Yan prided himself in his Level 180 Thief. He could barely be considered among the top experts in the game. Though, that was the only thing he could take pride in. He was penniless and unable to advance in life; a situation he was forced into by the enemy of his father. If it weren’t for the little money he made by selling off items in Conviction, he would’ve barely been able to eat. In the end, he chose to settle his matters once and for all. He assassinated his father’s enemy. He lay dying shortly after being shot in the pursuit.However, that wasn’t the end of his story. Instead, he awoke moments later to find that he had reincarnated into his past-self. Armed with his experience and knowledge of future events, he sets out to live his life anew.
