# Backpack & Warehouse System

Each user initially has 50(TBD) backpack spaces. When the backpack space reaches its limit, you won't receive more items. Therefore, please clear your backpack in a timely manner. You can clean your backpack in the following ways:

1. Sell items (different items have different selling prices).
2. Use/consume items.
3. Use in-game items to increase backpack slots.
4. Store temporarily unused items in the warehouse.

***Note: The backpack is divided into different tabs based on item types, and these tabs share the same backpack space.***
