So I was watching the Deidara vs Sasuke fight over and I found something very interesting. Sasuke said he was able to see Deidara's mines underground because his Sharigan allowed him to see the chakara the mines emitted from them. So I'm guessing Sharigan users can actually see chakara through walls and other objects. I just need to know if this is entirely true which I'm sure it is because this fight made it clear that he did see the mines underground because of their chakara.
