After six years, he was rescued by the Special Forces during their operation against that organization and was adopted by the captain of the Special Forces.

Years later, he joins the greatest VRMMORPG of all time, [Destiny's Fate] online, due to repeated invitations from his brother. He creates havoc inside the game as he climbs his way from being a beginner player to a peak class expert. But as he grew up, he became curious about his real identity and his biological parents. He tried to investigate it with the help of his brother and best friend. And after discovering his real background, he decided to follow in his father’s footsteps and stood at the peak of the world using his Martial-Art Skills and Mentalism Techniques.
ahh...this story is just like Child of Light, but it's a sequel I think. It turns out the author actually uses the same concept as Child of light but after some chapters, the story really changed. I think it's good. well good luck
