"How is she doing it?"
Karna was floating in the starry sky not understanding why or how the things in front of him were happening even when he tried to think of a little open-minded way.
The reason why it was so hard to believe for Karna was that the fox jumped from his shoulder and landed far away from him and then opened her small cute mouth.
As she did that the twinkling stars in this vast sly moved immediately, A large group of the stars surrounded her and then all kinds of food started appearing out of nowhere.
Not only that, The food he was seeing was also not right. Yes there were usual sweets but then Karna saw a fox eating cake. Yeah cake in his day and age.
For a moment Karna becomes already thinking someone might have figured out his time-travel capability but then scratches that thought as the boon he got from Lord Shiva protects him from others find out.
