In Naruto's training system, chakra control training was a process many ninjas had to undergo. Among them, tree climbing and water walking were the two most basic and important exercises.
After mastering the basic techniques of chakra control, Xin began attempting these two exercises. He knew that only through constant practice could he truly grasp the essence of chakra.
Tree climbing looked simple, but it actually required extremely precise chakra control. Xin stood beneath a tree, took a deep breath, then focused his mind and channeled chakra into his feet. He gave a light leap, grabbed the trunk with both hands, and slowly began climbing upward.
With every climb, Xin carefully felt the flow of chakra. He constantly adjusted his posture and strength, trying to find the best way to climb. After countless attempts and failures, Xin finally became able to climb skillfully to the treetops and stand high above, overlooking the entire village.
Water walking was an even more difficult exercise. Xin stood on the water's surface, feeling the waves surge beneath his feet. He knew that to walk on water, he had to perfectly blend his chakra with its surface.
Xin closed his eyes, took a deep breath, and evenly distributed chakra across his feet. He lightly took a step forward and felt the resistance coming from the water's surface. He constantly adjusted his chakra output, trying to find the point of balance.
After countless attempts and failures, Xin finally became able to walk freely across the water as if he were on level ground. He felt the connection between himself and the water growing ever closer, as though they had become one.
Though these two exercises seemed simple, they gave Xin a deeper understanding of chakra control. He understood that whether it was tree climbing or water walking, both required exceptionally precise control over chakra. This control would become an important foundation for him to become strong in the future.
After completing basic exercises such as tree climbing and water walking, Xin began to learn a more advanced chakra control technique—the Fine Control Method.
As its name implied, the Fine Control Method involved extremely delicate manipulation of chakra. It not only required ninjas to possess powerful chakra control, but also demanded a deep understanding and awareness of chakra's flow.
Xin stood in the training ground of the secret base, closed his eyes, and began trying to use the Fine Control Method. He felt the chakra within him flow slowly through his meridians like a trickling stream. He tried to guide that chakra with his mind, making it flow according to his will.
However, the Fine Control Method was no easy task. Chakra's flow was often elusive, and the slightest mistake could cause it to go out of control. During his initial attempts, Xin failed repeatedly, with the flow of chakra completely beyond his control.
But Xin did not lose heart. He knew this was a path he had to take. He continued practicing, trying again and again, failing again and again, then trying once more. Every failure gave him a deeper understanding of the laws governing chakra's flow, while every success brought him closer to his goal.
After countless sessions of practice, Xin finally grasped the basic principles of the Fine Control Method. He could guide chakra through his meridians with his mind and could even control its speed and direction.
This control greatly increased the power of Xin's ninjutsu. He could control the release of his ninjutsu more precisely, allowing its power to reach its fullest extent. At the same time, he could recover chakra more quickly, ensuring that he could continue fighting in battle.
However, Xin was not satisfied with this. He knew that the Fine Control Method was only one aspect of chakra control, and that he still needed to continue exploring and learning. He believed that as long as he did not give up, he would surely master all the mysteries of chakra.
