In Konoha, I Hand Over the Summit War Plan from the Start

Uchiha Yun had survived the Uchiha Clan's massacre by keeping his head down. He had planned to stay hidden until the end of time before making his move.

Unexpectedly, he awakened the Dungeon System, and its first dungeon was the Summit War.

After weighing his options, Uchiha Yun chose to turn the dungeon over to the village and persuade the Third Hokage.

"There are all kinds of Devil Fruits in there!"

"A single Devil Fruit could create a Kage-level powerhouse!"

"There are also three different kinds of Haki!"

"And a completely different way to cultivate!"

"…"

The Third Hokage: "I'm in!"

With the Konoha Sannin gone from the village, the Fourth Hokage dead, and Danzo lurking in the shadows, fortune favors the bold. The Third Hokage planned to use this opportunity to make Konoha stronger.

And there was even...

"The Yomi Yomi no Mi?"
