East Blue, Sky City's Central Research Institute.
Ever since Vinsmoke Judge successfully developed Second Birth, the largest and most advanced research base in the East Blue had begun preparations to study the cloning of various Devil Fruits.
Bruno's Door-Door Fruit, due to its special spatial properties, had been singled out by Roy and placed among the key research projects.
Compared to Zoan Devil Fruits, Paramecia Devil Fruits naturally posed far greater difficulties when it came to cloning.
However, Sky City's Central Research Institute had gathered most of the Pirate World's most brilliant minds.
Thus, under the combined efforts of Vinsmoke Judge, Caesar Clown, Queen, and even Vegapunk, the series of problems encountered in cloning the Door-Door Fruit—
—were ultimately smashed through by them with brute force.
Sky City's Tontatta settlement.
A high-tech plantation that incorporated the technologies of genius scientists such as Caesar Clown.
Door-Door Fruits were thriving one by one on fruit trees formed from a fusion of plants and steel.
The Tontatta were the best gardeners in the world.
They possessed an innate affinity with plants, so they naturally became the workers of the plantation in the Door-Door Fruit production facility.
As the first batch of Door-Door Fruits successfully ripened and fell.
The skilled Tontatta immediately placed the fallen fruits into enormous insulated containers. Shortly afterward, this batch of Artificial Devil Fruits would be inspected and sorted by specialized machines.
Tontatta after Tontatta carried enormous insulated containers utterly disproportionate to their bodies, darting through the lush vegetation.
The Devil Fruits they collected were then transported by conveyor belts into the laboratories behind this high-tech plantation.
There, all kinds of technical methods would be used to inspect these Artificial Devil Fruits.
Defective products would be destroyed directly, while successful Artificial Devil Fruits would be carefully placed into watermelon-sized insulated
