Chapter 15: Setting the Course for Training

As for what was happening with his Shadow Clone, Tetsuya was unaware. However, he received information from the system, which also credited him with attribute points.

Immediately, Tetsuya created another Shadow Clone. Although he hadn't learned the Multiple Shadow Clone Technique, it didn't mean he could only have one clone. Testing it last night, Tetsuya found that creating two or three clones wouldn't burden his body.

"Your mission is to find beasts in the forest and contribute to Konoha's stability," Tetsuya instructed the new clone.

Shadow Clone No. 2 couldn't help but roll its eyes. Pretending even with himself? Truly helpless.

After sending the clone off, Tetsuya found himself restless. Used to a busy schedule, a whole morning of lazing around felt unproductive.

"No, I can't think like this. How could I have such a dangerous idea?" Tetsuya shook his head, criticizing himself. But after lying on the bed for the morning, he couldn't take it anymore.

Even though Hinata was now busy with her family's rigorous training schedule and rarely visited, Tetsuya knew he couldn't just idle away. Reflecting on how Hyuga Hiashi trained Hinata in the original story, Tetsuya frowned. If he could, he would have a stern conversation with his future father-in-law. Training was essential, but the method mattered. High-pressure tactics would only crush Hinata's confidence.

He was still too weak to influence Hyuga Hiashi. Tetsuya resolved to focus on strengthening himself first. After lunch, he donned his training gear and headed to the training ground.

Konoha offered numerous training grounds for its ninjas, and Tetsuya had never used them before. It was time to start serious ninjutsu training.

Evaluation: You have great power but lack the knowledge to apply it effectively. With brute force alone, you are invincible against most Chūnin.

The panel was impressive, but the evaluation was harsh. Even Kakashi would struggle against him in a raw power contest. But ninja combat wasn't just about raw power; experience, tactics, and skill were crucial. Currently, Tetsuya's seal-making speed was his biggest weakness, barely managing three seals per second and often risking mistakes.

The system didn't count seals as a skill, offering no shortcuts. He had to train the traditional way. Although raising ninjutsu levels could eventually allow him to simplify or even eliminate seals, for now, he had to practice diligently.

...

"Hello, which training ground is available now?" Tetsuya asked the training ground office staff.

The staff member, surprised to see such a young ninja, checked the forms. "The No. 22 training ground is available. You can use it until six in the evening. The cost is one thousand taels."

Tetsuya nodded, paid the fee, and headed to the training ground. Konoha's training grounds were well-equipped, and the price was reasonable.

...

"Si, Wei, Shen, Hai, Wu, Yin—Fire Style: Great Fireball Technique!"

As Tetsuya completed the seals, Chakra surged within him. He expelled a fireball nearly five meters in diameter, its heat scorching the ground and evaporating water from a nearby pool.

The system panel indicated that the power of Tetsuya's ninjutsu depended on three factors:

Ninjutsu Level: Higher levels meant greater power.Chakra Nature Transformation: This provided a beneficial effect across all ninjutsu, akin to a buff.Chakra Quantity: More Chakra input increased power, but exceeding the caster's control risked failure. Thus, precise Chakra control was crucial.

Understanding these principles, Tetsuya set his training focus:

First, Chakra control. His talent was evident—climbing trees and walking on water came naturally. Second, Nature Transformation, which affected all ninjutsu. He particularly admired the flashy Lightning Style, inspired by future techniques like Chidori and Chidori Current.

Tetsuya decided to start with Lightning Style, aiming to become a versatile and formidable ninja.
