After a week,

 I went to the village and said all the things that I learned but the village did not accepted me

The king said shut up! You traitor. Go away!

 I went away from that village at that night then I went to the diamond

And

Soon after I went to the village a man came to me and said the king wants to talk to me then I went and talked to him.

 He said I heard your circumstances I want you to be a part of the village and also I want you to have the special training. What will you do? It is better living in the diamond then being homeless, right?

 I accepted it and they took me to the place where the special training will held.
