players can only enter the mine cave for mining at a specific time every day. The mine will open from 00:00 to 23:30 every day, and you can't enter the mine for the remaining half an hour. Then you can enter the mine at the foreman after the mine is opened. What players can dig in the mine is mainly black iron ore, which is an important material to strengthen our equipment
the ore cave is divided into three layers. The deeper the position is, the higher the output rate of black iron ore will be. Of course, there will be a greater chance to trigger the boss of the mine. After killing the boss, we can get a lot of rewards. In addition to the black body ore, a lot of slag may be excavated in the mine cavern. These slag can also be exchanged for black iron ore at the foreman. Ten slag can be exchanged for one black iron ore with purity of 1

it's better to dig against the wall when mining in the mine cave, or if you choose gold or silver ore, you will have a greater chance to dig black iron ore. Even if the players can't use it for the time being, they can also put the black iron ore on the exchange for sale and get a certain amount of Yuanbao
