An undertaking as massive as three countries-no, two countries-working together to carve out a river could hardly be kept secret. Nations across the Shinobi World sent people to investigate, and gained a new appreciation for Uchiha Mu's ability to stir things up.
How long had it even been? He had barely bought the Land of Rain before getting involved with Sunagakure. He must have planned it well in advance. They all turned their attention to the Land of Rain and sent spies there.
Hanzō had never imagined that the great nations' spies would one day join forces to keep watch on his Amegakure.
After spending enough time at home with his children, Uchiha Mu set out alone. He wanted to go to Rōran to confirm something: whether time travel was possible, and whether it meant traveling along a timeline or entering a parallel spacetime. He was curious, but had no intention of taking that risk before his children grew up.
After all, it would be awkward if he went and could never return. He could wait until his children were old enough to protect themselves. For now, he needed to claim that place as his territory.
Rōran was an oasis in the desert. Thanks to the dragon vein, it was spared the ravages of wind and sand, and quite a few people lived there. They were ruled by the Queen of Roran, who could control the dragon vein's power. The current queen was named Sera.
"The power to travel through time." Uchiha Mu gazed at the magnificent buildings and slowly walked inside.
Before long, a girl with dark red hair appeared before him. "Stop. This is Rōran. I am Queen Sera."
"Hello, Queen Sera. I am Uchiha Mu, leader of the Hundred-Clan Shinobi Nation," Uchiha Mu said with a bow.
