1, exchange props and equipment: players can collect souls to exchange all kinds of props and equipment, including very rich suits, to enhance the combat effectiveness and survivability of the characters.

2. Exchange for dark blocks: At the statue, players can exchange their souls for dark blocks. Dark block is a special material, which can be used to make a series of dishes.

3. Make a series of magic discs: The series of magic discs made of dark blocks can provide players with extra blue blood stripes. This blue blood bar does not participate in the blood bar calculation, but it can resist the poison gas damage equivalent to four times the normal blood volume. In the non-toxic gas area, the blue blood strip will automatically recover.
