Great Toad Sage Fukasaku explained patiently to Naruto:
"The fusion training is meant to ensure you have a steady, endless supply of senjutsu chakra during combat. You must understand that while Sage Mode is immensely powerful, it also consumes a vast amount of chakra. Without fusion training, you'd only be able to maintain Sage Mode for five minutes before reverting to your normal self!"
Hearing this, Naruto nodded in sudden realization and said:
"I see! I'll definitely work hard to complete all the training!"
After that, Naruto threw himself body and soul into the training with Jiraiya, focusing entirely on every punch, pouring his determination and effort into each one. Jiraiya's attacks were fierce and unpredictable, while Naruto constantly adjusted his defense and counterattack strategies. Their figures crossed like the wind within the small training clearing. Naruto dodged with agility one moment and launched brave assaults the next, his eyes burning with persistence and resolve. Every time Jiraiya hit him, Naruto quickly adjusted his state and reflected on his mistakes. Every successful block or counterattack gave him a deeper understanding of how to fight in Sage Mode. Sweat soaked Naruto's clothes, and his breathing grew increasingly ragged, yet his movements never slowed down in the slightest. Through spar after spar, Naruto constantly gathered experience and refined his techniques.
