In the mountains, Naruto Uzumaki lay on the ground, gasping for breath.
His body had already reached its limit!
But soon, he struggled back to his feet and picked up the rubber ball again.
Keep going... keep going.
That voice kept ringing in Naruto Uzumaki's heart, supporting him, encouraging him, urging him on.
"Whew..."
He let out a heavy breath, brought himself into the best condition he could, and tried again.
"Focus... focus... focus!"

His body even plowed a long furrow through the ground!
Tap, tap, tap!
Hurried footsteps rang out. Lin Mu darted out of the trees and braced Naruto's back with his hand, stopping his backward momentum.
Lin Mu glanced down and saw that Naruto's palms were already smoking.
His injuries were severe.
Jiraiya appeared beside Naruto as well, his eyes fixed on Naruto's palms.
He was deeply shocked.
What an incredible kid! His chakra was so dense it almost burned his palms. He really is full of surprises!
Not everyone could endure training at this level.

Beyond his shock, Lin Mu felt even greater admiration.
He knew he could not match Naruto Uzumaki's perseverance.
But Naruto was badly injured now,
