Daniel's appearance was quite odd. He did not appear to be in hell as a slave, but as a simple visitor. His clothes were clean, and he did not look at his surroundings in fear, but in curiosity. However, for how odd as he appeared, his presence was not enough to justify the behaviour of the young demoness' companion.
From a single look at the young demoness, Daniel was able to infer that her level of power was not something to scoff at. He presented himself as a low level human cultivator, who by logic, should not be able to feel the power of somebody at her level. Nevertheless, the faint wisps of immortal essence that he allowed out of his body were more than enough for him to feel the power of not only this demoness, but of her quadruped companion as well.
