Chapter 8: Jackpot

"The difficulty with this jutsu lies in compressing a large amount of chakra into the shape of a fire dragon in an instant," Mokuzuki explained while demonstrating the technique and discussing the intricacies of chakra manipulation with Shisui.

Recently, Mokuzuki had mastered advanced chakra nature transformation and shared a lot of his knowledge with Shisui.

"I see now. I think I understand a bit better," Shisui said, nodding and preparing to give it a try.

Shisui quickly performed the hand signs, causing his chakra to erupt and compress into shape.

"Fire Style: Great Dragon Flame Jutsu!"

Shisui released a one-meter-high fire dragon that soared into the sky, circled around, and then plunged into the water below.

Splash.

Mokuzuki clapped and smiled at Shisui, saying, "I thought you might need a few tries to get it right, but I must have underestimated your talent."

Mokuzuki was genuinely surprised. To learn a B-rank jutsu so quickly without the use of the Sharingan was impressive. Was this the value of having double S-rank talent?

"It's thanks to your excellent teaching, Master Mokuzuki," Shisui said modestly.

He acknowledged that he learned faster than the average person, but he genuinely felt that Mokuzuki's instruction was thorough and effective. Mokuzuki had used a single hand sign for the initial demonstration but performed the complete hand signs during the subsequent demonstrations, slowing down and explaining each step.

"And remember, you've only managed to use it; mastering it is another matter," Mokuzuki continued. Shisui still had a lot to learn, as the size and number of fire dragons were not yet on par with Mokuzuki's own technique.

"Then let me demonstrate the Great Dragon Flame Jutsu a few more times for you," Mokuzuki offered with a smile.

He was pleased with Shisui's humility and diligence. Watching Shisui's chakra steadily increase on the panel indicated that Shisui had been working hard even when he wasn't around.

Time flew by quickly when one was focused. By the time Shisui was absorbed in Mokuzuki's teaching, the sky had darkened.

As Shisui saw the firelight reflecting off the water, he realized how late it had gotten. He couldn't help but think that Mokuzuki's soothing voice might be a technique that made time fly by unnoticed.

"Master, I need to head home now," Shisui said, preparing to leave.

"I've also compiled some notes on chakra nature transformation techniques. Take a look when you get home," Mokuzuki handed Shisui a booklet.

Shisui paused for a moment, then accepted the booklet with a bow of thanks.

Though he didn't say much, Shisui's respect for Mokuzuki grew. Despite only having known each other for four days, Mokuzuki had never held back, always teaching him the most important things without reservation.

Watching Shisui leave, Mokuzuki smiled with satisfaction. His most valuable resource had once again yielded something great.

[You gifted your disciple a chakra transformation training manual. Due to the disciple's gratitude, you received a bonus reward: Wind Style: Pressure Damage (Proficient)]

Mokuzuki's mind was instantly filled with detailed information on the Wind Style: Pressure Damage technique, along with additional knowledge on wind chakra nature transformation.

He was very pleased with the reward. Wind Style: Pressure Damage was a top-tier wind jutsu with a large area of effect and powerful destructive capabilities. It also complemented his fire style techniques.

Moreover, the wind nature transformation knowledge would aid in developing the Rasengan with the wind attribute. Although he originally intended to develop the Rasengan's fire attribute, having wind knowledge would allow him to enhance the Rasengan's form first.

After several days of experimentation, Mokuzuki had figured out the reward mechanism for teaching. The rewards were influenced by both the quality of what he gave and the disciple's gratitude, with the latter being more significant.

The next day, he had given Shisui a small snack, and the system rewarded him with ten shuriken. On the third day, after giving Shisui homemade food, the system rewarded him with fifty chakra points.

The quality of the rewards improved with the perceived sincerity of the gifts. Mokuzuki realized that the third day's gift had a more substantial impact because Shisui valued it more.

Understanding the mechanism, Mokuzuki planned to aim for a significant reward. He decided to check Shisui's profile the next day to find out his birthday.

...

On the fifth day of Mokuzuki's time in the Naruto world, he had only one class scheduled. However, an office request for a substitute teacher for a third-grade class provided him with an opportunity he couldn't pass up.

By taking on two classes, Mokuzuki earned twenty chakra points and the Great Fireball Jutsu. This was his first time receiving a jutsu he already knew, but he was delighted to find that the repeat jutsu system directly increased his proficiency with the technique.

If it were a game, it would be like earning an extra life or enhancing his Fireball Jutsu.

"Sensei, you're too accommodating. With your attitude, other teachers will definitely ask you to substitute more often," Ueda Aya expressed her concern.

Mokuzuki was thrilled at the prospect. "We're all colleagues, and I enjoy teaching students," he replied with a smile.

Ueda Aya was at a loss for words. She couldn't believe someone would willingly work for free, substituting classes without additional pay. It seemed too good to be true.

The weekend arrived quickly. The ninja school followed a similar schedule to his previous world, with classes Monday through Friday and weekends off.

As planned, Mokuzuki met with Obito and Might Guy at eight in the morning and took them to the training spot where he and Shisui practiced. They began their "special training."

"Why do we have to get up so early on a weekend?" Obito groaned on the desk Mokuzuki had prepared.

"Early? It doesn't feel too bad to me," Guy said, scratching his head, unable to empathize with Obito.

Mokuzuki handed them the test papers he had prepared, reflecting their current progress. Since they had only been in class for five days, it was inappropriate to use last year's exams. Instead, Mokuzuki focused on easier questions to ensure they could score well.

"What's this, Sensei?" Obito asked, puzzled.

Shisui arrived soon after and saw Obito and Guy struggling with the test papers. He looked curious.

"They're fourth-grade students, and I'm giving them some extra tutoring. You focus on your training; it's not a problem," Mokuzuki explained.

Shisui's presence was intentional. Mokuzuki thought it would be amusing for the senior students to see their junior peer training while they worked through boring test papers.
