As a nephew, why does the immortal have a different attitude towards Xu Feng Run Yu under the moon?

Although Xufeng and Runyu are both sons of the Emperor of Heaven, the difference is that Xufeng's mother is the Emperor of Heaven, while Runyu's mother is just a princess who was exterminated.

Xu feng can be said to be born aboveboard. In contrast, Runyu is very humble. He is an illegitimate child and it is very difficult to survive in his own race. He was once pulled out of Longlin by his mother because he is a dragon. His mother is a carp and he is a dragon. Children of the same race think he is a monster.

After Runyu was brought back to heaven, she grew up with Xufeng. Originally, the relationship between the two people was particularly good, which was what Moon Fairy saw in her eyes. However, Tianhou has always spoiled her son and favored Xufeng. Many things like strange jade. After a long time, Runyu's heart became no longer pure, and gradually became murderous, which is also an important reason why Moon Fairy changed her attitude towards Runyu.

Both of them grew up under the moon, but in the process of growing up, they developed in different directions Runyu was originally a water god, and Xufeng was a fire god. Their lives are in conflict with each other and water and fire are incompatible. When they grow up, Runyu is always thoughtful and preoccupied.

Runyu is always oversensitive, but Xufeng doesn't have too many ideas. She will share anything good with Runyu and regard Runyu as her own brother. In order to protect Xufeng, the immortals under the moon stand on Xufeng's side no matter what they do.

What happened later was also expected by the immortals under the moon. Both of them like golden honey. Runyu did a lot of things he shouldn't have done in order to get golden honey, and even betrayed Feng Hsu. Immortals under the moon see it in their eyes, so they have different attitudes towards Runyu.
