Seafaring: The Collection System, with the Four Emperors Working for Me

Zhou Si transmigrates into the world of One Piece and becomes a low-ranking soldier in Sabaody. He activates the Everything Collection System.

But the System's collection requirements are outrageously difficult: Kaido's blood, Big Mom's photo of the nun, Whitebeard's naginata, Shanks's Gryphon!

Even the easiest items include Hancock's hair, Doflamingo's glasses, Kuma's book, and Crocodile's hook...

"The easiest targets are all Warlords of the Sea or higher. System, are you messing with me?"

Just then, Zhou Si spots Rayleigh passing by, and his eyes light up.

So Zhou Si trades Rayleigh's beard for a lucky mooncake, Rayleigh's hair for a wish-fulfilling pill, and Rayleigh's blood for a Anywhere Door!

What should he do when he's run out of Rayleigh's stuff to trade? Go find the Four Emperors and "borrow" from them, of course!

And so, amazing items like bodyguard robots, repair and destruction potions, erguotou, and alignment-switching guns come into being!

The Four Emperors go on wild rampages all over the place to get their hands on these amazing gadgets, working for Zhou Si in the process!
