Marine, An Eight-Year-Old Inventor, Created Seraphim At The Beginning

Linley traveled through the world of pirates and became Kizaru's younger brother, an eight-year-old kid!

What can an eight-year-old kid do? Obediently stay under the blessing of Admiral, eat and wait to die... But at this time, a technology system is activated, and when it comes up, it will give you the top technology in the pirates [Seraph]!

Anyway, I have nothing to do, so I will study it blindly, and I never thought of directly causing a sensation... From Shichibukai-level Seraphs, all the way to Admiral-level, Four Emperors-level, and even Overlord-level Seraphs.

It directly brought an unprecedented huge boost to Marine, and at the same time directly subverted the pattern of the pirate world!

Not only that.

With the birth of the second technology [Arbitrary Gate] and the third technology [Second Devil Fruit], the plot of the pirates began to get out of hand...
