The dragon felt pissed. Noah was basically ordering it around, and he wasn't even trying to be polite in the process. However, his idea made far more sense than it wished it to.
The aspect of the world inherited by the death dragon made it unable to think of approaches that could save lives. Yet, it wasn't alone on the battlefield, and its power still allowed it to share information with its companions.
The death dragon raised its head and gave voice to a deafening roar that forced every existence on Heaven and Earth's side to cover their ears. The flying cockroaches clearly couldn't defend against the attack, so many of them died to protect the strongest members of their swarm.
The leader set off and returned toward the battlefield at that point. Noah could only stare as the massive beast left his vision, but his companions didn't give him the chance to remain immersed in his thoughts.
