"As I said, it is a sentient being, we cannot be sure of what it is thinking, we can only assume, 

And in this case, 

I believe it is because of his cultivation level. 

Since Nux cannot devour it anyway because he is a Semi Saint, it must have felt safer appearing in front of him. 

Another reason could be that it must have felt that he was the weakest compared to all of us since he didn't make a move. So it must have wanted him to be greedy and die during the process, one death would raise the tension between us and sow the seed of distrust, once that happens, it is highly likely for us to end up against each other."

"Anyways, now that it is here, why don't you devour it?" 

Felberta spoke with a light smile on her face.
