After hearing Tsunade's words, Shin Uchiha smiled and asked softly, "Tsunade, would you like to learn the Senjutsu of Shikkotsu Forest?"
To keep her skin from turning dark, Tsunade had come up with all sorts of excuses. Just as she was about to continue, she heard Shin Uchiha's casually delivered question and immediately shut her mouth. None of those excuses would come out anymore. She fixed her eyes on him, waiting to see what he would say.
Seeing that Tsunade had fallen silent, Shin Uchiha gave a smug smile. He had put quite a bit of effort into coming up with this idea.
"Tsunade, you should know how strong the Third Raikage's and Fourth Raikage's defenses are. They gained that level of defense by training their Lightning Release Armor to its highest stage. So I think that if you reach the third stage as well, the defense it provides should let you withstand some of Katsuyu's acid. With me beside you supplying life force, you should have a chance of mastering Shikkotsu Forest's Senjutsu."
As Tsunade listened to Shin Uchiha, her eyes grew brighter and brighter. How could she not want to master Shikkotsu Forest's Senjutsu? It was her grandfather Hashirama Senju's signature ability. Mastering it would give her strength an enormous boost.
Why was Jiraiya so strong? Why had he been able to catch up to the genius Orochimaru and Tsunade, who possessed the Senju bloodline? It was because he had mastered Mount Myōboku's Senjutsu, which had greatly increased his strength.
And Shikkotsu Forest's Senjutsu was an even better match for Tsunade's Ninjutsu, capable of bringing a qualitative leap in her vitality and healing abilities.
The more Tsunade considered Shin Uchiha's sudden inspiration, the more plausible it seemed. That was why her eyes kept brightening.
But then Tsunade suddenly
