It wasn't just Orochimaru who felt this. Even the others in their sleep sensed that something was off.
Of course, they did not wake because of it.
Their brows merely furrowed slightly on their sleeping faces before they continued their deep slumber.
It was not just people. Ninjas had stronger senses than ordinary people because they cultivated Chakra and possessed superior physical abilities. But among ordinary people alone, their perception of the surrounding environment was not as sharp as that of animals.
For instance, when natural disasters such as earthquakes struck, animals could sense them in advance and flee to avoid danger.
Thus, when Naruto's body became one with the surrounding magnetic field, animals throughout the sheep pens, cattle pens, and pigsties opened their eyes. Some bulls even thought dawn had arrived. Startled, they scrambled to their feet, instinctively intending to find some cows and get to work.
But when they opened their eyes, the bulls discovered that it was still dark. Then they noticed several non-Breeding Rams in the nearby flock panting away as they secretly indulged themselves.
Hah, why were they so keen on something so boring and exhausting? Sneaking around to watch in the middle of the night, too.
That was what the bulls thought.
The Breeding Rams thought the same as the bulls. That sort of thing was torturous. Doing it all day left them too weak to stand, yet these fellows were secretly doing it. They simply could not understand.
If those non-Breeding Rams knew what they were thinking—and if they could speak—they would surely curse loudly: Pah! You well-fed bastards have no idea how starving we are! You don't even leave behind a single drop! What about us? We don't get any chance to let it out at all. They're practically turning into relics!
