Everyone's Castle: Survival in the Caves, Random Skeletons

Billions of human beings descended into the caves to participate in the struggle for hegemony among all races. At the beginning of their arrival, every human being will be randomly assigned to the first-level arms of a certain race. Humans, orcs, elves, undead, elements... In a cave with earth on all sides. Zhang Yue transformed into a skeleton in the undead camp. Forced to participate in the cave survival. Push forward or shovel back. Should I obtain supplies, combat skills, magic, or directly receive a box lunch? Zhang Yue has a clairvoyant eye and can get hints. Zhang Yue has innate skills and can level up super quickly. There is an unguarded treasure chest ahead. The left side is dangerous, don't dig. When everyone is trembling and cautious. Zhang Yue was already heavily armored and took the lead in changing jobs, running rampant in the underground world. Ps: This book has rich races, skills, and magic. This book contains an excavation adventure in the cave world. There is also a racial battle for national hegemony in the castle. I just want to write a smooth and enjoyable fantasy novel. Collect it first! Maybe it looks good? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
