The Grave Robbers' Chronicles: Trapped in a Game Dungeon

Chen Shi was an ordinary office worker on Earth. He had been muddling through life, and should have spent his whole life in quiet mediocrity! But who could have guessed that, in the blink of an eye, he would be born again from his mother’s womb? This was a world almost identical to Earth. To Chen Shi, it seemed Heaven had given him another chance to choose how to live. So, still swaddled in his crib, he swore he would study hard and get into a top university, escaping the aimless life he had led in his previous life. But as he slowly grew up, he realized that things seemed to have gone far beyond his imagination. The enormous transparent objects suspended in the city sky, the dungeon points his parents talked about, and, oh yes, the rankings: everything showed that this had absolutely nothing to do with Earth... At sixteen, everyone at school awakened their professions. Three days later, they were all sent into a dungeon arranged by the academy for upgrade training. Hey, can someone tell me how to leave this dungeon? There’s no exit button on the panel in my mind. Stay calm, there has to be a way out! Chen Shi reassured himself. But why did this human cub, whom the panel had classified as a carbohydrate, sound so unreliable? What did he say his name was? Wu Yiqiong~(⊙o⊙)! It seemed kind of familiar! Then Chen Shi heard that he had a second younger brother named Wu Erbai. That was when Chen Shi lost his composure!...
