But after a while, it will pick up quickly. . . Now, back to the synopsis. Er-Erhmm.. (narrator-voice on) ... In another world called Blue Star, the famous son of wealth, Dorian D. Tian, is thrown into a whirl of unfortunate circumstances, resulting in his death. . His parents had a brutal car accident that left them in a coma, and his uncle had quickly taken over the company,  and seized the company, making sure that he was financially crippled for good. With that, the famous young master struggled desperately. And in the end, he gave in to his despair and depression, leaving the sad, lonely world. The end? Heh... Think again! Because in that brief moment, the lifeless corpse suddenly opened its eyes, revealing a deep calm look. That's right. Another mysterious soul had entered the body. But if one thought this story was just about revenge, then sorry... that wasn't even the half of it! .... The mysterious entity suddenly triggered an exorcist system. And from then on, both humans and even those from the underworld shuddered in fear and despair at the mysterious soul's cruelty. [Humans]: "Demon! Demon! You're definitely a demon!" [Demons]: "Help! Help! The famous demon wants to eat me!" [Evil Spirits]: "You!... Are you the one who is an evil spirit or us? Why the hell did it seem like you're the demonic one instead?" [Ghouls]: "You stay away from me! Stay away from me now, you evil entity!" [Hellhounds]: "Are you sure you're not the son of hades?" The system couldn't help looking at its host in doubt. Its indicators said that its host was indeed mortal. But why did it feel like something was wrong with its host? Dorian lightly chuckled in amusement. He would also like to ask the same question. What exactly was his identity? Well, this would be the biggest mystery of all. But Dorian wasn't in a hurry. Who were his enemies, and who were his allies? Soon, he would find the truth. In the meantime, why not play a little? "Demon! stay back!" "Oooo~~~... I... I want to go back to the underworld where it's safe." "Run for your lives! The demon is here!" …..

The live show, Survive in Wilderness was a hit. There were thousands of participants in the game show. They would all start by parachuting from a plane and land randomly in a primary forest. The participants would have to rely only on a backpack, a water bottle, and a dagger to survive. Yu Beier was only eight years old when he joined the game show so that he could buy the cure for his ill mother with the prize money. He was the youngest to have ever participated, and he had accidentally woken up a wilderness survival system. [Ding! You have received the Wilderness Survival 101 Pack!] [Ding! You have received Max-leveled Hunting Skill!] [Ding! You have received Max-leveled Building Skill!] [Ding! You have received Max-leveled Swing Skill!] … When the show started, the viewers were utterly shocked. From climbing the tallest mountain to crossing the ocean, conquering the forest and swamp, and managing an island, there was nothing that Yu Beier could not do. “Dude! That eight-year-old boy is living a much more interesting life than us!” “Yu Beier is the apex among men!” "Whenever I see his stream, it feels like I've just lived an extra life!"
