# PVE levels ### • **Level system** The game contains up to 100 levels for gamers to pass through and advance to another level. Each level needs to consume the pet’s durability in order to continue to the next. ### • **Level type** 1\. Ordinary level: The treasure box will only drop “energy crystals” and character experience, and this type of level cannot be replayed. 2\. BOSS level: In addition to “energy crystals” drops and character experience, the treasure box will also unlock a pet that is corresponding with the boss. Gamers can play this type of level repeatedly. When the gamer pass through the BOSS level for the first time, a pet will drop for sure. However, there is only a probability of dropping in later levels. 3\. Challenge levels: The treasure box will drop “energy crystals” and character experience, as well as pet skill books. When the gamer pass through the level for the first time, this skill will drop for sure. However, challenging the level again later will only drop with probability. 4\. Mineral level: There is a probability that “crystal buildings” will drop. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
