You're too kind to me

"All these things looked impossible. How can I transform into others, animals and nature? It's unbelievable!" I questioned, but the ghost began to pass down the knowledge of the needed pills for the stage. It was unfortunate that the drugs were among the earth-level medications. However, sincerely looking at it, the level of this pill was high and shouldn't be grouped as earth level.

"I know what you are thinking! However, the intention of grouping such a high-level pill under the earth level is simple: it had flaws. Regardless, it's good enough for your level. Although you've grown, it is not enough to take such potent pills. But before you go to the prince world, you should be able to use heavenly pills if you grow more than you are now."

"So, what's the flaw of this medicine?"

"The changes are not permanent: it has a duration. However, the more you take it, the more it helps your body's physique malleability. It would gradually progress to permanence."
