When Shingetsu found Tobirama, he was with Shamon from Sunagakure. Like a pair of geeks, they were utterly absorbed in tinkering with the model in front of them.
The moment Shingetsu suddenly walked in, she caught both their attention. Shamon's eyes in particular lit up as though he had discovered some treasure.
The bald tough guy, normally so stern and hard-bitten, instantly plastered an ingratiating smile across his face. He hurried over and greeted Shingetsu with boundless enthusiasm:
"Lady Shingetsu! It's been so long! You've come at just the right time. Please take a look at Sunagakure's latest achievement!"
Shingetsu approached and discovered that the model before them was actually an enormous sand table reproducing the border region between the Land of Wind and the Land of Fire.
On the sand table, a trainlike model slowly traveled along a track, moving easily through both the winding desert terrain and the rugged, varied mountain landscape.
"This is Sunagakure's latest research achievement, the Thunder Carriage!"
Pointing at the train model on the sand table, Shamon proudly explained:
"With this, we can easily cross the Land of Wind, the Land of Rain, and the Land of Fire, transporting large quantities of cargo and passengers in a single trip."
"This is quite good."
After a moment's thought, Tobirama offered his assessment in all seriousness. Coming from him, that was high praise indeed, and Shingetsu nodded in agreement.
Deep down, however, she could not help muttering to herself:
Isn't this just a train?
The shinobi world even has trains now. Civilian technology really does advance by leaps and bounds in times of peace and stability.
Tobirama gazed almost spellbound at the electric train model in his hands, as though he could already see rail lines stretching across the entire Konoha Shinobi Nation.
One major problem
