"The Second Exam!!" (第二の試験!!, Daini no Shiken!!) is chapter 45 of the original Naruto manga.
Naruto isn't intimidated by the "Forest of Death". Anko cuts his cheek to punish his cheekiness. She goes on to explain that the second phase will require the genin teams to obtain both an earth scroll and a heaven scroll upon entering the forest and make it to the building in its centre within five days. Each team will be given one scroll, necessitating that they somehow take the scroll that they need from another team. After everybody signs consent forms releasing Konoha from responsibility in case of their deaths, the twenty-six teams of three are granted entry to the forest.
