Cain did not allow himself to lose focus. He had the strength to destroy those trees if he wished, but it would require considerable effort. Each one was massive and deeply rooted, feeding on the continent's ambient essence. Burning them to ash would take time—too much time. Time enough for Azazel and his forces to arrive, surround the area, and strike with their full might.
Worse still, Cain could not ignore the obvious: those trees were not merely parasitic growths but conduits of power that could be channeled into the forces of Azazel's side, making fighting near them dangerous.
Though the sight filled him with fury, Cain forced his emotions into stillness. He had learned something invaluable. This was Azazel's countermeasure to the Scarlet Intercontinental Formation.
