There are four occupations to choose from in the crystal nucleus: swordsman, musketeer, nurse and puppet master. When the role level reaches 15, you can change jobs, which is equivalent to upgrading your role and gaining more core skills. A good feature is that you can change careers freely before awakening at level 40. Each profession has two optional transfer roles.

In addition to normal attacks and jumping evasion, each class also has 8 special skills, 2 killer skills and 1 pet skills. The way of bonus points determines how the characters play in the game. Every occupation has a skill tree, and you can get different skills by choosing different occupations. Gold coin is one of the most common currencies in the game, which can be obtained in various ways and has a wide range of uses.

Although you may think that gold coins are abundant at first, with the improvement of the level, all aspects of promotion need gold coins to support, and gold coins have become the scarcest resource. Equipment upgrading is a bottomless pit of gold coins, especially in the later period of high-intensity equipment strengthening, which costs hundreds of thousands of gold coins at a time. Buying emblems also requires a lot of gold coins, and the market value of different emblems is different.

Game function system:

Players can get fleet funds by signing in, completing fleet tasks and daily tasks of mine warfare. According to the progress of fleet technology research and development, the fleet needs to pay maintenance funds every day, and the funds will be deducted at 6 o'clock every day. If the fleet fund reserve is insufficient to pay the maintenance fund, it will be deducted to 0.

The captain can choose the fleet upgrade scheme, and the daily fleet funds are given priority for fleet upgrade, and the excess is deposited in the fleet fund account. There is an upper limit to the storage of fleet funds, and the upper limit will increase with the improvement of fleet level. If the obtained fleet funds exceed the storage limit, the excess will not be accumulated.

The task of the fleet is completed by all members of the fleet. Players can get personal rewards for participating in fleet tasks. The upper limit of the fleet's weekly employment from fleet tasks is affected by scientific research and development.
