"He's mentally ill," the Bull-headed Demon said with experience, "Mentally ill people just don't have normal male or female emotions, he even lacks the physiological needs that both normal and abnormal humans have."
"..."
Although demons had some understanding of the human world and various humanistic aspects, just like having specialties, their experiences made their knowledge differ, each focusing on different feelings.
For instance, compared to the Bull-headed Demon who had been raised by humans, the Tiger Demon's understanding of the human world was very superficial.
At first, it couldn't even understand why the Bull-headed Demon felt that Su Daji calling him "Bull-headed Man" was bitterly insulting.
Latter, it learned and would use "Bull-headed Man" to address the Bull-headed Demon when angry, instead of "Bull Demon King."
But it was clear now that they couldn't afford to anger the Bull Demon King.
