Is the masked man fighting Huo Ying and Namikaze Minato a speck of dust or a piece of soil? Why?

The cartoon version has been published, and the true identity of the masked man is soil, not spot. Diandian died long ago, and this ninja war was reborn with mud. Only one hole in the mask exposed his eyes, and his other one was transplanted to Kakashi. Therefore, fighting Namikaze Minato is about using soil.
