Go to all the maps of the shadow world and look for elite monsters marked with red dots in the small maps.

When killing this monster, there is a chance of chaotic time cracks. After entering the crevice, the player can beat all monsters in a limited time to get the treasure chest, and there is a certain chance to get the gem when opening the treasure chest.

Killing some elite monsters will leave some boxes. When you open the box, you are sure to get 30 shadow coins. We can exchange NPC's shadow coins for props such as gem powder in the safe house where the map of the logging field is burned down.

In Lulu's shop, a lucky merchant in the king city of Traya, there is a chance to have a jewelry box of 1-3 stage. If you click refresh, you may also refresh the high-grade gem box and fashion gem box, and sometimes you can brush out the third-grade gem if you are lucky.

After the mining skill reaches the third level, the 1 gem box can be produced by collecting materials. We will build our own treasure chest and open the gems that have the opportunity to gain combat power.
