Chapter 146: EMERGENCE OF THE SEAFARERS ALLIANCE FLEET.

Somewhere deep below the Mediterranean Sea, an enormous and heavy armor-protected military base stood, spreading as far as the eyes could see, though it could not be seen.

The water around the area was completely calm and still, no creature was in sight, making the surroundings look like an abandoned part of the sea.

The outer surface of the military base blended with the dark blue color of the underwater environment. The addition of strong stealth measures made the base completely undetectable by animals and even other human devices.

As calmness reigned, an alarm suddenly started ringing inside the base. All the originally white lights turned red, indicating that it was an S rank alert.

Military alert signals are in 7 different categories. There are the F, E, D, C, B, A, and S, and they are categorized according to their order of importance. Following this order, the S rank alert was the highest grade of security alerts.
