With current technology, even using the entire Zero-Tails as an energy source would not be enough to maintain the normal operation of the entire route network.
However, Orochimaru also told Nawaki that if Magnet Release chakra could be used directly as an energy source, the energy conversion process could be skipped, increasing efficiency dozens of times over. With the Zero-Tails' chakra reserves, maintaining a route network spanning the entire continent would be more than feasible.
Upon learning this, Nawaki immediately thought of Sunagakure's One-Tail, Shukaku. It was the largest source of Magnet Release chakra in the entire shinobi world. If the Zero-Tails could obtain Shukaku's Magnet Release ability, the greatest obstacle before him would be solved at once.

Nawaki ordered the monks of the Fire Temple to build a temple near Sunagakure specifically to seal the One-Tail, while stationing large numbers of troops there in rotating shifts. In truth, they were monitoring Sunagakure while using the One-Tail to threaten it.
Of course, according to the agreement between the two sides, Konoha could only seal the One-Tail and did not possess ownership over it. Sunagakure could also send people to study the One-Tail, but the two sides had to share their research results.
