Chapter 396: Great Toad Sage
From that day on, the intense and exciting research and development of the new technique began at the Senju mansion.
Because it involved the Nine-Tails, its significance to Konoha was undeniable. Orochimaru and Jiraiya were both fully committed, temporarily setting aside their usual duties. Scrolls and books were brought in one after another, turning the mansion into their makeshift research center.
Naturally, this commotion couldn't be hidden from Nawaki—though it was likely Mito's intention for him to notice. Within two days, Nawaki learned the painful truth: his grandmother's time was running out. At first, he struggled to accept it, but soon, he chose to spend every moment by Mito's side. Time, after all, was the best medicine.
Though unable to contribute to the research, he and Tsunade took on the role of observers. As the days passed, the three-month deadline approached.
"How has the new technique been progressing?"
Kawakaze revealed his toned upper body, exhaustion evident in his eyes. Using his brain all day and working at night was wearing him down.
"It's going well. There's just one more key point," Tsunade replied. "I think it'll be done in a week at most."
Her hair was disheveled, and faint traces of red lingered on her face. She leaned against Kawakaze's arm, her plump figure partially curled up and exposed.
"What's the key point?" Kawakaze's large hand moved idly, pretending to navigate.
"Does that even make sense to you? Can you understand it or solve it?"
Tsunade rolled her eyes. Truthfully, she couldn't fully explain it herself. While her knowledge of Fūinjutsu surpassed Kawakaze's, there were limits. Even together, they couldn't match Orochimaru or Jiraiya, let alone Mito.
