章 877: The Black Tortoise Array

Boom!

The entire dark space seemed to be shaking. Vast and mighty black fighting spirit seeped out from the darkness like a black ocean and dominated the dark space.

Mu Chen eyed the space in front of him warily. The black fighting spirit had already changed into an ocean so vast that its ends could not be seen, with huge waves and a growl roaring out endlessly from its depths. A terrifying sense of oppression emanated from this black ocean formed by the fighting spirit.

The Spiritual Four Battle Array could already be considered to be truly activated. Therefore, the space they were in would reveal its savage side very soon.

Mu Chen glanced backwards and waved slightly.

Boom!

The moment Mu Chen made the gesture, the Nine Nether Troop and the Blood Hawk Troop behind him almost simultaneously burst out their fighting spirit. Two powerful fighting spirits emerged together in the space behind Mu Chen.
