Sparrows were also considered as adaptable birds. During the winter, their feathers would be more resistant to the cold weather. They would save up on food way before winter and when winter finally arrives, they would still hunt for food in the morning but they had relatively far less physical activity.
The little sparrow by Lu Xiaoyu's side looked very fast, but it was in fact not in control of itself. Whatever action it executed was controlled by Lu Xiaoyu.
"How long can you control this sparrow? Will your celestial energy be depleted?" Lu Shu asked curiously.
"There's no time limit. No usage of celestial energy whatsoever," Lu Xiaoyu replied in glee.
Lu Shu was shocked. Why did his manipulation of the sword, The Corpse of the Dog, required the constant use of celestial energy while Lu Xiaoyu had such a good skill?
"No usage of your energy for the entire duration?" Lu Shu asked with a darkened face.
