In the Era of Stars, there are four different ways to obtain resources. Among them, the most important way to get city-building resources is through mine challenges, which are crucial for upgrading and building various structures. For players who haven't unlocked this feature yet and want to learn more about it, the following will provide a detailed introduction to this gameplay, as well as some tips on how to play more steadily!

I. Introduction to Mine Challenges
There are two types of mines in the game: the first type is called Original Stone Mines, and the other is Essence Mines, producing original stones and essences respectively. Both are essential resources for upgrading different buildings later on. The mines have different levels, and you can only unlock the next level by defeating the current level's guards. The higher the level, the more resources produced per challenge, and correspondingly, the stronger the guards. Each mine challenge is a one-time battle that does not consume your real troops, but also does not support relay battles; only one team can be dispatched to decide the outcome in one round. If you fail to challenge the next level, you can directly sweep the current level's mine, with each collection taking five minutes.

II. Strategy Guide
Firstly, since mine challenges do not consume troops and you only have one chance, it is recommended to send out your strongest team to ensure victory over the guards. After level 20, each subsequent level significantly increases in difficulty. You can first open the corresponding mine to see the type and specific strength of the stationed guards, then choose the troop type that can counter them, which will greatly increase your chances of winning. Under a counter relationship, even if the dispatched force has a slightly lower combat power than the guards, there is still a good chance of winning.

Secondly, when challenging, try to choose mines that are closer to your base. This reduces the marching time when dispatching troops, avoiding being ambushed by malicious enemies. Additionally, if possible, activate the monthly and weekly cards, which significantly reduce the time required for resource collection. This not only improves development efficiency but also prevents attacks from opponents' main forces. You can also send your own teams to raid those who are currently mining, allowing you to acquire more resources faster.

The above content introduces how to play the mine challenges in the Era of Stars. This challenge must be completed daily, especially on servers where wars are frequent. Accumulating more resources quickly allows players to establish a foothold. Those who haven't started yet should hurry up and begin!
