[Multiple Devil Fruits] [One Female Lead] [Armament Haki + Supreme Grade Great Blade] [Koby’s Strictest Father] [Zephyr and Garp’s Beloved Disciple] [Buggy’s Talent Scout]
After transmigrating as Zoro’s senior disciple, Xiurui thinks he can use his System to dominate one corner of the world. But who could have known the clone fruit granted by the System would be so useless? He has no choice but to find another way.
So his real body joins the Marines and becomes a great hero of the Navy.
His clone becomes an underground merchant, conducting covert deals with pirates of every kind.
“Crocodile, you wouldn’t want your secret getting out, would you?”
Hearing Xiurui’s threat, Crocodile breaks out in a cold sweat.
“If you can save Bonney, I’ll accept any fate.” Kuma looks at Xiurui, overcome with emotion.
At Marineford, seeing the Marines standing ready to face the Whitebeard Pirates, Xiurui’s lips curl into a faint smile. The next moment, Whitebeard at the height of his power appears in Marineford.
“Sorry, Senior Brother Xiurui, but I have to stop your dream.”
So says Koby, the king of deserters who left Garp stranded in the New World.
“Hey, Buggy, if you stop here, it means this is all you are. Do you really think a man like that deserves to compete with Red-Hair for the great treasure?”
Hearing Xiurui’s words, a sharp glint flashes in Buggy’s eyes. His Conqueror’s Haki awakens! The Chop-Chop Fruit awakens!
Looking at this battered world, Xiurui slowly draws Supreme Grade Great Blade: Dojigiri Yasutsuna. “The world ruled by Imu ends here. If you’re set on this, then charge with me into Mary Geoise, take down those self-important Celestial Dragons, and pull Imu from the throne in the Flower Room!”
It's pretty good. The characters in the original work are well restored.
The system that cheats the protagonist at the beginning, and then starts the event of clearing out the weak ones on the first island.
