Shinra Tensei was a Rinnegan technique that centered on its user, repelling everything around them—including ninjutsu—and dealing damage to it.
It sounded simple, but seeing Shinra Tensei with his own eyes still made Suifeng's heart sink.
The thing was not only astonishingly fast; it was completely unreasonable.
"Repel" didn't begin to describe it. It practically smashed everything away, like a heavy truck speeding down the highway and slamming into someone with such force that it left them utterly shattered.
Nagato had clearly not fully adapted to this power yet, and this was his first time using Shinra Tensei. Its power and range were both far inferior to what they would become in the future.
Moreover, the technique seemed to consume a tremendous amount of chakra. Suifeng could sense Nagato's chakra rapidly draining away with a single use, until he seemed to be running a deficit.
And since he was running a deficit, after using Shinra Tensei, Nagato passed out from the chakra he had expended.
"Nagato, are you all right?!"
Konan caught Nagato as he began to collapse, then glanced at Yahiko, who had just suffered a grievous injury but had managed to struggle to his feet. She secretly breathed a sigh of relief.
Yahiko struggled to his feet, his gaze somewhat vacant. He, too, had been frightened by the power Nagato had unleashed.
"Is it those eyes?!"
Nagato's eyes were clearly no ordinary eyes, and that was no secret among the three of them. Even their teacher, Lord Jiraiya, had probably taken them in years ago because of those eyes.
But over the past few years, the eyes had shown few signs of anything special. Nagato had told them that they were constantly consuming his chakra, but none of them had expected them to unleash such tremendous power today.
