Watching the two men steadily close in, Hatake Sakumo took a slight step back, doing his best to keep them from surrounding him from both sides.
He kept both of them within his line of sight.
Just as the AB Combo prepared to join forces against Hatake Sakumo, purple chakra energy suddenly appeared from a spot atop the mountain. Explosive Tags tied to Kunai landed in the center of the battlefield, and the explosion interrupted them.
They both looked up in unison. Uchiha Yuu's purple chakra energy was exceptionally conspicuous.
Knowing that Uchiha Yuu had survived the Tailed Beast Bomb, Killer B assumed the chakra in his body was nearly depleted. Yet Uchiha Yuu still dared to show himself before them. Killer B extended his tentacles between the mountain peaks, intending to cut off Uchiha Yuu's retreat.
Facing the approaching tentacles, Uchiha Yuu did not make the slightest move to evade them. Instead, he took two steps forward. His voice echoed through the empty valley, and a single sentence made Killer B deeply wary.
"If I were you, I wouldn't do that. Even if the Tailed Beast Cloak on your body can protect you from radiation energy, everyone fighting in this canyon will die—including A beside you!"
After fighting him, Killer B knew that horrifying poison could instantly take a ninja's life. Even though his brother was protected by Lightning Release chakra, that power was far too strange. He did not dare let A take such a huge risk, let alone the companions inside the canyon.
For a moment, Killer B found himself constrained. In that brief lapse, Hatake Sakumo found an opening. He swiftly stepped onto the mountain and arrived at Uchiha Yuu's side. The two stood shoulder to shoulder, drawing a clear boundary between themselves and their enemies.
