Dudian knew that it wasn't an illusion. He verified it few more times. His nails were able to cut through indestructible metal as if he was cutting through a butter. He didn't put any effort at all.
Next moment, he tried to cut the linen bag but previously sharp nails failed.
Dudian was alarmed. He grabbed many things around to check if he was able to cut through them. At the end he came to understand that his nails would reveal this strange ability once they came in contact with metals only. If he tried to cut flesh, blood, hair or anything else they would be just like ordinary nails just a bit more sharper.
"The hardest is the medal out of all that I had tried." Dudian's eyes lit up as he was surprised. He had the scientist side to him which was pondering about the issue. The metal was absolutely harder and solid than fabric. After many experiment he saw that nails were effective only against the metal.
Is it about the particles?
