I! Sarutobi Hiruzen, the Strongest Third Generation in History

Traveling to the world of Naruto, becoming Sarutobi Hiruzen,
Just like in the anime, Hiruzaru Sarutobi relied on his own efforts to firmly sit on the position of the Third Hokage, but as time passed and he was injured in World War II, his strength and body began to gradually decline.
In order to protect his own interests and consolidate his position as Hokage,
Hiruza Sarutobi gritted his teeth, with the mentality that I would rather bear Konoha Village than Konoha Village, and began to gradually walk towards a road of “blackening” and guarding Konoha Village, which is completely different from the original book.
But… at the critical moment,
The plot change system is activated, and you get the peak [Admiral of the Navy-Warring States Template] at the beginning.
So far,
the one who lives the longest,
The strongest Hokage in history was born.
