Jiraiya took Meihui and Naruto to look for Tsunade, asking around for news of the Fat Sheep all along the way.
He didn't idle away the journey, either. He planned to teach Meihui and Naruto the Rasengan.
One day, Jiraiya found a spare moment and said to the brothers with an air of mystery, "Hey, brats, I've got an incredibly awesome jutsu. Want to learn it?"
Seeing his expression, Meihui already knew what it was.
Jiraiya formed a blue orb in his hand, but just as he was about to show off, Naruto interrupted him.
"Tch, isn't that just a little Rasengan? You're acting like nobody else can do it." As he spoke, Naruto formed an orb of his own.
Jiraiya's jaw dropped in shock, his mouth wide enough to fit several eggs.
Then, with spectacularly bad timing, Meihui formed a Big Ball Rasengan with one hand, leaving Jiraiya dumbfounded all over again.
These brothers were absolute freaks. They had both mastered the Rasengan, which had taken even Minato three years to develop.
"Since you've already learned this, I'll teach you something even more powerful. The reason I'm called the Toad Sage is because of Mount Myōboku's Senjutsu."
"Now, let me teach you this jutsu. Listen carefully, because I'll only explain it once. Unlike ordinary ninjutsu, Senjutsu involves absorbing natural energy to enter Sage Mode. When you enter Sage Mode, markings appear around your eyes, and your ninjutsu is enhanced, turning into Senjutsu."
"Senjutsu has tremendous destructive power, and training to enter Sage Mode isn't easy. You need to go to Mount Myōboku to sense natural energy. You must combine the natural energy you absorb with your own physical energy and spiritual energy in a 1:1:1 ratio. Only then can you produce senjutsu chakra, enter Sage Mode, and develop markings
