**🎯 $ERT Mining**

📌 Mining Approaches

As players become more experienced, the stronger Heroes and Squads they train, the more profits they can reap, which requires more incentives by obtaining Eternal Rock. There are two kinds of Eternal Rocks in the game:

* Regular Eternal Stone

By occupying a Regular Eternal Stone, players can continuously earn $ERT.

* Advanced Eternal Stone

By occupying an Advanced Eternal Stone, players can continuously earn large amount of $ERT.

📌 Obtain Methods of Eternal Rock

NEO FANTASY allows players worldwide in one server. The pass of each chapter in Main-Quests of the whole server will unlock an Eternal Rock scene with massive amount of Eternal Rocks. Each refresh of the player interface comes with 15-20 Eternal Rocks in a random proportion, including Advanced Eternal Rocks and Normal Eternal Rocks.

Players can manually refresh the Eternal Rocks, and the first five times a day are free, which are shared by all the eternal stone scenes. After that, subsequent refreshes will cost a certain amount of $ERT.

The game system will automatically refresh the Eternal Rocks of all scenes at 0:00 UTC+8 every day.
