Shen Fei was not surprised that Mobius could break the rule preventing Devil Fruit users from possessing two abilities. Even Blackbeard could break that rule, let alone Mobius. Vegapunk might have been formidable, but only within this world.
Who was Mobius? The greatest biologist of the Previous Civilization. Among everyone Shen Fei had encountered so far, she was unquestionably the strongest in biological research. May was formidable as well, but as far as Shen Fei knew, she was more of an all-rounder. In other words, her overall abilities surpassed Mobius's, but in biology alone, she might not have matched Mobius.
Likewise, Vil-V was undoubtedly the genius of machinery. In that field, even Stark would probably fall somewhat short. It was not merely a matter of intelligence; the worlds themselves were different.
"The people in the World Government are probably going to have a hard time with this. Whatever. The final battle is coming soon anyway." Yamato had openly revealed the power of the Azure Dragon. Shen Fei was merely surprised, but everyone else was horrified—especially the spies of the World Government and the Navy. This was something beyond their understanding.
The World Government and the Navy had never stopped infiltrating pirate crews, especially powerful ones. Aside from a few exceptions, any notable pirate crew would have spies within it. Take the Centurion Pirates, for instance. A crew anyone could join just by calling someone Dad was simply too easy to infiltrate.
Of course, that only applied to ordinary crew members. It was not so easy for spies to become officers. Even the Centurion Pirates were no exception. Whitebeard was no fool, and neither were the captains under his command.
The Beasts Pirates were much the same. Again, this only applied to ordinary crew members; it was difficult for undercover agents
