Turning into a dragon is not strange. This is Ian's second time experiencing such a clear feeling of 'transforming into another creature.' The last time was when he accepted the Qing Steel Dragon's inheritance and transformed into its juvenile form within the dragon's memories.
Back then, Ian merely felt the Qing Steel Dragon's growth and experiences through its 'memory' from a perspective akin to playing a game...
This time, however, it feels incredibly real.
At the very first moment, Ian felt as though he was floating in an intensely concentrated saline solution. His body was curled up in a curved, enclosed space, and he discovered that the number of limbs he could control exceeded that of humans. Especially noticeable was the tail behind him; its sensation was particularly vivid because it was wrapped around the outer layer of his body and pressing against the hard walls of the curved space.
This is a dragon egg. He was inside the dragon egg.
"Interesting."
