Pirates: I help Robin and Queen become stronger together

The Grand Line is full of surprises, and it is reasonable for multiple unlucky people to be dressed in different clothes. Yun Tianxiang was dressed in the sea and accidentally ate a devil fruit, the natural floating cloud fruit. He can use the floating cloud to replicate the abilities of any other natural fruit! An unexpected drift, he became Luffy's companion! An unexpected encounter, he and Nico Robin became friends! An absolutely unexpected accident, he was remembered by Boa Hancock!!! The ancient imperial ruins, the myths and legends that have been passed down through the ages, everything is buried with some secrets. Is the fishman the product of life evolution, or the failure of scientific research? Where did the giants come from, and what are the feathered people from outer space...
