Look further around before deciding

"Hm whats this?" Naruto asked, he approached a large tube that was on wheels. "It's fine cannon. Casts a field around large areas that allows the user to use the other devices without anyone caring other wise." He read. "Weird name, but good to have."

He summoned some clones and had them bring the cannon to the roof. Using a screen on the cannon he input himself as the user, and the area being the hidden leaf. Once done he fired the cannon, creating a large stream of light that went into the air before a dome was erected around the barrior of the village.

He smiled and turned around, only to see Tsunade, Sakura, and an anbu with purple hair standing behind him.

"Naruto what just happened?" Tsunade asked.

"What do you mean?" He said nervously.

"I remember seeing a bright light from around here, but now i cant seem to find it. Sakura and Cat here came with me to investigate." Tsunade explained.

The cannon must be working then if they cant see it at all. Naruto thought to himself.

"No idea, i didn't see anything. I actually just got up here." Naruto lied.

"Huh. Weird." Sakura said. They turned around to return to the tower when Naruto realized he had one of the devices.
