"Blood of the Uchiha!!" (うちはの血!!, Uchiha no Chi!!) is chapter 68 of the original Naruto manga.
While using the Lion Combo on Yoroi, Sasuke's cursed seal starts to activate. Fearing disqualification, he suppresses it and defeats Yoroi, impressing everyone watching, particularly Orochimaru. Kakashi takes Sasuke away to seal off the cursed seal, disappointing Sasuke since he wants to see the other matches. Shino Aburame and Zaku Abumi are selected for the second match.
