The Treasure-Seeking Dragon of the Planes

As a dragon egg stolen from the vast Immortal Realm by a Planar Trader, I have so many grievances I can't voice.

Ever since Planar Trader Qin Cheng'an stole her away, the dragon egg he named Long Cancan developed a rudimentary consciousness and awakened her inherited memories.

Long Cancan's instincts told her that if she hatched, she would definitely become a contracted beast, so she stubbornly refused to come out of her egg.

Then she could only watch as Qin Cheng'an smuggled her out of the vast Immortal Realm, bringing along a large batch of its specialties, and arrived at a square, boxy residence called the Qin House, in a basic material plane named Earth.

Later, Qin Cheng'an was imprisoned in a Planar Prison for crimes including interplanar smuggling. Long Cancan was automatically bound as Earth's Planar Trader. With her treasure-hunting skill, how far will she go in interplanar trade? What planes will she discover, and what treasures will she find?
