How to open the wreckage of the galactic battleship?

Tactical hall has been activated. Among the remains of the galactic battleship in constellation, the remains can bring different types of skills and basic bonuses, which can be divided into active and passive categories. Passive relics will take effect immediately after they are unlocked, and there will never be a tasting period. Active remains need to be activated through the tactical hall.

The tactical hall is located in the lower right corner of the space interface, and commanders can enter to direct operations. Not only are props such as shield-free, fire upgrade and defense enhancement displayed in front of you, but all active relics can also cooperate with your strategic wisdom to show their talents and instantly repel the enemy thousands of miles away!
