3.After unlocking the slot, you will see these items, these are 心法 ,u know that blue icon.

As you can see, the lower left corner of these items is its level, you need to increase its level to complete the task you have been blocking you.

4.Select one, then click 修炼(↓red arrow in picture) to enter the next interface. (If you do n’t have these props, tell me)

After you click, you will be here, choose some props to give it experience, let it upgrade to level 1, and you can complete that task.
