One Piece: The Ice Demon Emerges, and the Age of Demons Begins

Han Xin transmigrated into the world of Jackie Chan Adventures, but never expected to arrive far too early: more than ten thousand years in the past. She became the ninth demon, the Ice Demon Han Xin, the youngest-born and youngest demon. She did not belong to the Eight Demon Sorcerers' astrological signs, and should have been the weakest demon of all. But with the memories and mindset of a human from her previous life, and by turning the astrological signs' double-edged nature to her advantage, she caught up through sheer effort. To the shock and admiration of the other eight demons, she became the strongest of them all, ruling the far south.

But a thousand years later, while she was in seclusion cultivating, the Eight Immortals sealed the eight demons one by one, then joined forces to take her on. She was no pushover, however, and the two sides fought for nine days and nine nights. In the end, both were left badly wounded. The weaker Immortals were gravely injured and fell unconscious, forcing them to leave this world for various special reasons.

She, too, was beaten to pieces. But the Eight Immortals never imagined that a fragment of her core would drift into the Sea of Worlds, cross several thousand years, and descend upon a world's natural land of ice and snow, where it began repairing itself automatically.

After waiting a thousand years, Han Xin finally recovered her original form and returned. Then she was dumbfounded: this was the world of One Piece!

To be clear, this is not a System novel. This is not a System novel. This is not a System novel. Some things need to be said three times.

Even without a System, Han Xin can turn the current world of One Piece into a golden age of demons, and bring the other demons into this world one by one.
