Why Did I Suddenly Travel to a Primitive Person While Lodging in an Internet Cafe?

Do you understand the value of eating hot pot in primitive times? No system, no cheats, no World of Warcraft, no myths, everything is done by hand! What? Don't even know how to use fire? What? Only eat barbecue and drink raw water? What stage will my tribe develop into? Agricultural society? Industrial society? Information age? Or is there something else...?
