Chapter 317:
The reason Obito investigated the source of Orochimaru's forces in the Sound Ninja Village was quite simple.
These ninjas not only had mysterious origins but also interfered significantly with his plans. To eliminate the problem at its root, Obito and Zetsu began investigating directly.
With their abilities—perception, surveillance, and controlling ordinary villagers to gather intelligence, it wasn't hard to locate the Sound Ninja Village. Once they had the location, finding the lab wasn't particularly difficult.
Both the original Orochimaru and the current Orochimaru were notoriously cautious. Even with advanced reconnaissance abilities, it was incredibly challenging to locate his secret labs.
But now, Orochimaru seemed unconcerned about the Sound Ninja Village laboratory.
The lab's output was minimal, and his forces had already grown so much that even if the lab were destroyed, it wouldn't faze him.
More importantly, Orochimaru had anticipated this exposure from the moment he brought Nagato to the village more than a decade ago.
Was he worried?
Not in the slightest.
