My Infinite Inventory and Auto-Training Space

Transmigrated into a fantasy world with the ultimate cheat code: a boundless inventory space that cultivates your power automatically while you sleep! Ten spirit fields with time acceleration? Check. A mysterious shop that sells everything from rare artifacts to legendary techniques? Double check. There's just one tiny problem—activating it costs 100 spirit stones, and our protagonist is completely broke. Watch as a penniless transmigrator transforms from a struggling nobody into an unstoppable force, buying his way to the top while his powers grow on autopilot. Why waste time grinding skills…
