My Magic Dragon Wives

My name is Leo, the second prince of the Cron Empire on the Continent of St. Mier. I have been weak and sick since I was a child. In order to cure my disease, my father used the forbidden art and made a deal with the magic dragon Clarissa. Therefore, I got married to a dragon egg of Clarissa. From then on, I had the same strong body as the dragon and incomparable demonic talents. When the egg broke, I found that the damned dragon Clarissa was a big liar. There were twelve female dragons in this dragon egg!
