One Piece Fragment Synthesis System

The protagonist travels from Blue Star to the world of pirates and obtains a synthesis system that can summon characters of various levels. Currently, only characters from the Naruto world are summoned, ranging from the Yonko level to ordinary soldiers. He also obtains the ability of the Eternal Mangekyō Sharingan and the Meat Ball Fruit. Madara, Hashirama, Izuna, Tobirama, Naruto, Sasuke, Orochimaru, Jiraiya, Tsunade, Namikaze Minato, Kaihuang, and Kaden can all be summoned. No invincibility at the start, no harem, only the empress Every time I read the novel, I see that the summoned characters are all women, and there are not many men at all. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
