Hello @Cuahangsung87. 
 

Have you perhaps started the Heatran quest recently? During this quest, the NPC Buck will take away all your Rare Candy and Master Ball(s) until you’ve completed the quest. Once finished, speak with Buck again and he will return your items.

I hope this clears things up. If you have further questions, please let me know.
