Building an intelligence network was no great challenge for the Black Emperor Pirates.
The Black Emperor Pirates were at the height of their power. They only had to ask the Underworld Kings they worked with, especially those with influence in the Four Seas.
If those contacts paid a little attention to young pirates, reports would naturally come in.
But that was not enough. Teach needed accurate intelligence on those pirates' personalities, abilities, and even their histories so he could choose his targets.
The Black Emperor Pirates could not go after every young Devil Fruit User. Those with ordinary abilities were not worth it, and neither were those with powerful backers.
For this, they needed more than their own network. They also needed the World Economy News Paper.
The Black Emperor Pirates already had dealings with the World Economy News Paper.
After all, the paper needed good relations with the Sea Emperors.
And the World Economy News Paper was more than a newspaper.
Backed by the World Den Den Mushi Group and the Landis Kingdom, it also wielded considerable influence in the Underworld.
It operated on both sides of the law and sold intelligence in the Underworld.
That was an important source of income for the paper.
As soon as Lubbock learned of Teach's idea, he passed the news to Dark Night.
Dark Night was an underground intelligence organization founded by Hades's mother, Nyx, the Night Lady. It had existed since the era of Rocks.
After the Rocks Pirates fell, the Netherworld had absorbed it and taken control from the shadows.
It had the Kronos Kingdom behind it.
Over the years, Dark Night had grown into a major intelligence organization with considerable influence across the seas and in the Underworld.
Intelligence often passed between different organizations.
Very little escaped their notice.
