A scroll appeared in front of Naruto
"What is this?"
"It is a scroll that allows you to make a pact with dragons, so you can call for help at any time, you just need to write your name with your own blood" explained Eragor
Naruto nodded as he signed the scroll.
"Now it's time for you to learn the Dragon Sage Mode, the first step is to enter that fire"
"WHAT ?! THIS IS NOT ENFORCABLE!" the blond objected
"Listen, if you have a pure heart, these flames won't do you any harm"
The blond man pondered the Dragon's words for a moment, in the end decided to listen to him and enter the flame. At first he put his finger on when he noticed that nothing was burning him, he put more and more of his body in, and finally he entered the whole place, he only felt an incredibly pleasant heat.
"Amazing, I'm standing on fire but the fire doesn't hurt me."
"This fire is full of my energy, therefore it does nothing to people with pure hearts, the second stage of training is to absorb as much of my energy as possible and then learn how to use it"
"I understand"
Naruto went in the meditation position, starting to collect Eragor's energy from the flames, at first nothing happened, but after a while blue scales appeared on the blonde's hand
"What is?"
"Don't worry about it, it's a dragon senjutsu effect, continue with your quest"
"Hai"
Meanwhile, the fifth team reached Konoha, they immediately went to the Hokage's office to file a report.
"I see, well I'll send an ANBU squad to try to find Naruto, you have a few days off, you can go"
"Hai"
