So, what area in the entire Shinobi World still had gaps untouched by ordinary technology, while also holding the potential to become indispensable to all humanity?
The things no one could live without were nothing more than clothing, food, housing, and transportation. After comparing the Shinobi World with his previous life, Nawaki ultimately set his sights on transportation!
Due to the Shinobi World's unique environment, every human possessed an exceptionally strong physique. Especially when it came to movement speed, even children only a few years old could run like the wind.
Although ordinary people were far slower than shinobi, if they truly ran at full speed, they would be no slower than the horses from Nawaki's previous life!

When civilians in the Shinobi World traveled or conducted business, they basically relied entirely on their own two legs! That was also why merchant caravans hired shinobi for protection. It couldn't be helped—everyone ran ridiculously fast. Those hauling cargo definitely couldn't outrun the bandits, so they needed shinobi guards to stay safe.
Nawaki had once asked Orochimaru and the Research Department to imitate an internal combustion engine and build a primitive automobile! Yet in the end, it had been dismissed as a "toy," because the fire-nature internal combustion engine used Chakra extremely inefficiently. Not only was its speed poor, it also consumed an enormous amount of Chakra. Its practical results were even worse than simply having shinobi run on their own legs!
Although that line of thinking had been rejected, Nawaki had never given up on the idea of creating a mode of transportation. Shinobi were indeed highly mobile, but ordinary civilians moved much more slowly, and transportation
