Sovereign of the Firmaments

The monotonous voice resounded in Lucas' head as he looked in the direction from where the loud roar came.

Lucas saw a huge tortoise that was like a huge black mountain.

It let out another roar that was way more powerful than before, which gave rise to some unknown fear in Lucas' heart.

The host is affected by the [Black tortoise]'s battle cry.

His battle prowess will be decreased by 10 percent for the next 10 minutes.

Lucas was shocked to hear the system notifications in his head as he looked at the huge black tortoise with a serious look on his face.

'Decreasing my battle prowess with a roar? This is a true monster.'

Lucas knew he had to use his full power to fight the Black tortoise after getting a debuff from the monster.
