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.

Two years ago, the mere fifteen-year-old scion of the Lin family, in front of the colossal behemoth that is the Murong clan, made a vow!Two years later, no one knows what he has gone through, but from the moment of his return, he radiates a brilliance that seems to compete with heaven and earth!(Note: The protagonist of this book is very aloof, cold, and passionate. Those who like to read about a military king's ambiguous romances and flirts, please bypass this one.)
