In other words, this 3 signifies that Chen Ming can now control three cruisers.
The total amount of spiritual power required to control three cruisers is at least enough to control over thirty destroyers.
There's not much difference between a destroyer and a frigate, so Chen Ming didn't notice a significant change when he first controlled a destroyer.
But compared to a destroyer, controlling a cruiser is a qualitative leap.
As Chen Ming progressed from controlling destroyers to cruisers, his spiritual power has also undergone a qualitative change.
Thus, his panel has a new development.
Overall, Chen Ming now has a considerable amount of spiritual power to allocate to other tasks.
For example, controlling the Spirit Awakening Nerve Extractor, managing various research lab equipment, and supervising cloning research institute machinery.
Monitoring Dusk's activities stealthily without them noticing.
