"How was that possible? Why did my Rasengan only injure him a little instead of killing him? This is really strange." After seeing the injured enemy stand back up, Ruri frowned slightly and spoke under his breath.
When the other enemy saw Ruri's expression, he walked over to him with a smile and said, "What's wrong, brat? Curious now? Then let me tell you. We each have two especially thick steel plates on us, one in front and one behind. Your Rasengan is useless against us. At worst, we only suffer minor injuries. It can't kill us at all."
After hearing what the enemy had just said, Ruri smiled too, then said to him with a smile, "Oh, so that's how it is. I couldn't tell you were so prepared. But even if you're wearing thick steel plates, so what? My Rasengan might be useless against you, but don't forget that it isn't the only Ninjutsu I know."
At that moment, the enemy Ruri had blasted away slowly walked toward them. He looked down at his tattered shirt, then tore it off, revealing the two thick steel plates.
"Brat, I have to admit, your attack really was powerful. There's a clear dent in my steel plate. Who would have thought you would be this strong at such a young age? We really did underestimate you just now," the enemy said to Ruri with a smile as he came up beside them.
Ruri also saw the two steel plates on the enemy's front and back. At that moment, he thought to himself, I really didn't expect these enemies to have some brains despite being relatively weak. To think they prepared in advance. This will be difficult now. Rasengan is already useless against them. I wonder whether Eight Trigrams Palm will work.
