The pack of sharks couldn't do much after they lost their leader. Noah killed all of them and let his dark matter absorb their bodies. His power had allowed the Devils to end the battle in no time.
Still, the Devils and the environment as a whole had changed during the battle. The laws didn't belong to Heaven and Earth anymore, but a similar transformation had happened to the other creatures.
The surviving Devils had grown dark. The mutations that they triggered didn't reflect the chaotic other world's will anymore. They tried to push the matter to evolve, which made them closer to Noah's ambition.
Of course, Noah was still unaware of his surroundings. The state of his consciousness didn't improve, but the other Devils had developed a connection to his existence.
Noah's actions didn't even follow his instincts. They were the mere result of the other world's will that filled his mind, but his existence had begun to affect its power.
