The Treasure-Hunting Game Has Arrived, and I Have an Upgradable Secure Container

(Treasure-hunting game + the protagonist’s secure-container slots can be increased + no System) A treasure-hunting game descends upon the world, completely changing how everything works. When they turn eighteen, everyone becomes aware of a special entrance. With a mere thought, they can enter another world of treasure hunting. Search, hunt for treasure, fight, extract... The treasures they find can be kept, exchanged for the game’s currency, or traded for various items and materials. They can even spend in-game currency to bring certain items into the real world. Countries shift their focus to developing these game worlds, and begin researching them in earnest... Special government agencies and treasure-hunting academies are established to train experts in the field. Meanwhile, in a city in southern China, someone destined to shake the entire treasure-hunting world is preparing for his very first expedition. “No! Who said this guy pulled a twelve-slot red? He’s totally naked!” “I really saw it!” “Then tell me, how are you supposed to fit a twelve-slot red into a secure container with only nine slots?!”
