The Pet Raised by Pirates at the Beginning Is Called Akainu.

Ye Feng traveled to the world of One Piece and got a system similar to raising pets, except that the pets he raised were different from others. By raising a little red dog named Akainu, Ye Feng gained the ability of Sakaski rock berry fruit as well as the Haki of seeing and hearing color and armed color. Raising a little eagle named Eagle Eye, Ye Feng acquired Mihawk's extremely powerful swordsmanship. By raising a little snake named Nine Snakes, Ye Feng gained Hancock's domineering aura. In this way, Ye Feng opened a zoo, named King Kong of the Warring States Period, a chick named Qing Pheasant, and a little rabbit named Peach Rabbit. And because of such a name, Ye Feng made the Navy Headquarters go crazy. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
