Eruption.

All the guard units at the front stood with rapt attention. They looked at the horizon, and their emotions began to fluctuate. The air around the place was getting more and more heavy. The soldiers were waiting for any moment so that they could attack in return, but they could not sense anything. 

Old Yan and Shi Lang stood at the forefront of the forces, but they did not have any restlessness on their faces. The terran was not used to this but was not impatient either. Old Commander Yan asked, "Commander Ace, what should we do?" 

Shi Lang smiled and said, "We do not need to do anything. Look at the sky. The blood moon is not out yet." 

The people raised their heads and saw the sky covered in clouds. Old Commander Yan narrowed his gaze as he said, "No wonder they have not acted yet. The clouds are covering the skies and blocking the blood moonlight." 

Shi Lang nodded and replied, "I feel the attack will be led by flying demonic beasts."
