Learning by doing

Kazuya felt a surge of power as he picked up chakra points and combat experience from the two women.

"Lady Tsunade," Kazuya said with a smile, "I've just arrived in the Land of Hot Water. Would you like to join me for breakfast?"

"Isn't that a bit much?" Tsunade hesitated.

But her stomach growled, giving her away.

"Let's go together!" Kazuya laughed.

"Alright," Tsunade agreed, a rare blush of embarrassment on her face. Shizune, holding her pet pig, looked at Kazuya curiously.

"He seems nice," Shizune thought. "Just like in the reports, he appears to be a kind person."

The three of them enjoyed a hearty meal at the hotel. Tsunade, who hadn't eaten in over a day, felt warmth spread through her body.

"Lady Tsunade," Kazuya said, "I've booked a room here. You and Shizune should stay too. It's convenient."

"That sounds good," Tsunade nodded. Her eyes shone with gratitude as she thought, "What a nice guy! Just as the reports said, maybe even kinder!"

After breakfast, in an open field, Kazuya and Tsunade faced each other.

"Kazuya," Tsunade said, "Lord Sarutobi sent me a letter asking me to take you on as an apprentice. But first, I need to see your strength. Let's fight with all our might. Show me your limits!"

Kazuya nodded. He had been wondering how to demonstrate his skills to Tsunade, and now the opportunity was here. 

"Then be prepared, Lady Tsunade," Kazuya said softly.

"Ha! Don't underestimate me. I am Tsunade!" she laughed heartily. Shizune watched curiously, eager to see Kazuya's strength.

"Bring it on!" Tsunade beckoned.

"Alright." Kazuya nodded and in the next instant, his form turned into a blur, appearing before Tsunade almost instantly.

"What speed!" Tsunade thought, surprised by his Body Flicker Technique.

Kazuya's kunai swept dangerously close to her. Tsunade, deciding not to hold back, threw a punch.

The air exploded with force. Her legendary strength left cracks like spider webs in the ground. Her fist aimed straight at Kazuya.

Kazuya quickly dodged, moving out of the range of her powerful attack. The ground where Tsunade's punch landed shattered.

Kazuya absorbed the chakra and skills Tsunade released during the fight. He picked up 500 chakra points, 50 points of Yang Release talent, and gained the skill Superhuman Strength.

The destructive power of Superhuman Strength was incredible, much more potent than regular ninjutsu. It was a perfect complement to the Flying Thunder God Technique.

"Fire Style: Great Fireball Technique!" Kazuya executed the jutsu, creating a fireball over 20 meters in diameter that rolled towards Tsunade.

Shizune, watching the match, was stunned. "That's the Great Fireball Technique? It's enormous!"

Tsunade's expression grew serious. "He's not just any ordinary ninja!"

The massive fireball exploded with a terrifying roar. Tsunade dodged swiftly, knowing she couldn't take on such a powerful Fire Style ninjutsu directly.

"He's tough," Tsunade thought, her expression tight with concentration.

Suddenly, a white light flashed beside her.

"Take this..." Tsunade swung her leg down with tremendous force.

The area 100 meters around them shook. The surrounding forest broke, and the ground cracked under her powerful kick.

Kazuya remained calm, prepared for Tsunade's attacks. He didn't intend to defeat her easily, knowing she was one of the legendary Sannin.

Then, several clusters of golden light flew towards Kazuya, changing his expression.
