Which episode is Naruto Kakashi taking off his mask?

Naruto Kakashi took off his mask in episodes 10 1 and 689.

In episode 10 1, at the instigation of Naruto, Sakura Woody and Sasuke decisively joined the plan to uncover Kakashi. They invited Kakashi to eat Lamian Noodles because they thought Kakashi would lift the veil when eating. But I didn't expect Kakashi to take off the veil for an instant, and his teammates like pigs appeared. Enoch blocked Naruto's view, so the plan to spy on Kakashi fell through.

After the seventh task, Naruto wants to find something to do. Later, he was curious about Kakashi's true face and wanted to explore it. At this moment, the photographer Skye appeared.

Skye and Naruto sneaked into the archives, and when they found Kakashi's file, they were discovered by the secret service. Naruto, who was not going to give up, pushed Kakashi to the wall with the help of his partner.

Kakashi was a cold and rational person when he was a teenager. My father committed suicide in childhood, so he closed his heart. Later, he became the sixth generation of Huo Ying and retired many years later. Naruto inherited and became the seventh generation of Huo Ying.
