P.S.: The rating is low because it just opened.
Transmigrating into the body of the Third Hokage, he immediately encounters a situation where the Second Hokage has died in battle and he is surrounded by powerful enemies.
"Hiruzen, for the sake of the village, a root must penetrate deep into the darkness!"
"Well said!" Hiruzen Sarutobi slapped his thigh. "Danzo, the village is currently under construction and funds are tight."
"Previous funding, equipment, and expenses..."
"Let the Shimura family take on this responsibility; it's all for the sake of the village!"
Danzo: ? ? ?
With countless tragic ending scenarios at his disposal, Hiruzen Sarutobi chose a completely new path.
After the end of World War II, Danzo spent the entire night studying the matter before arriving at the Hokage's office.
At the very top of the scroll, several large characters are written in an extremely vigorous brushstroke—
Draft of the First Five-Year Modernization Plan for Konohagakure
"puff--"
Hiruzen Sarutobi spat out the mouthful of tea he had just taken a sip of.
Five...Five-Year Plan?
He stared at Danzo in front of him, then at the plan on the ground filled with "violent aesthetics" and "iron-blooded style," and was completely dumbfounded.
This art style is off!
How come you, a schemer who engages in assassinations, espionage, and plots to seize power, have suddenly switched careers to urban planning?
"Hiruzen, my road is repaired! It grows faster than Sakumo's pigs!"
"Hiruzen, I've drawn three versions of the reservoir plans. Which one do you think is best?"
Looking at the infrastructure fanatic in front of him, who was holding construction blueprints and was more enthusiastic than anyone else, Hiruzen Sarutobi fell into deep thought: Did I... turn him too straight?
