Suffering a Dimensional reduction blow

When Musk bypassed the ice storm, he was first attracted by the two that had been fighting ignoring everything else. But when he shifted his line of sight, even with his personality, he could not help but become fiery in his heart. But the look on his face did not change, otherwise, he would fail himself as a ten-thousand-year-old monster. Even though he could not rival those in the Nivarna Domain in terms of lifespan, he is still considered an old antique when placed back in the world he was reincarnated in.
