"The Absolute Defence: Crumbled?!" (絶対防御・崩壊!?, Zettai Bōgyo: Hōkai!?, Viz: The Ultimate Defence… Crumbles?!) is chapter 83 of the original Naruto manga.
The Sunagakure representatives are shocked that Lee has managed to strike Gaara. After Lee lands some additional blows they begin to grow concerned, as Gaara is becoming increasingly more interested in the fight. Gaara reveals that his body is coated in a layer of sand which has absorbed the impact of Lee's attacks. Knowing that there is nothing he can do about this defence, Lee opts to attack in such a way that not even Gaara's armour can protect him. Lee uses Front Lotus on Gaara, but during a brief series of pain, gives Gaara the chance to escape his grasp.
