The landmass' forces continued to overwhelm their opponents, and the dragons managed to stand out even in that chaotic environment. Heaven and Earth's assets couldn't help but lose ground as creatures born with the sole purpose of destroying them unleashed everything they had.
Roars, battle cries, orders, and far more filled the higher plane, but the soundwaves caused by the impacts of the various spells overwhelmed all of that. Rumbling noises, explosions, and so on fused to create the greatest chaos that the world had ever witnessed.
Hoping to find order among that mess was delusional. Even the rest of Noah's forces soon abandoned their idea of finding suitable targets and started slaughtering anyone nearby. Ending in the wrong spot at a bad time meant death, and Heaven and Earth's assets weren't used to facing those stakes.
