"Ta-da! My gift to you, Konoha's highest secret—the Scroll of Seals! You may not have heard of it, kid, but all you need to know is that it contains various ninjutsu and forbidden jutsu written by the Hokage of every generation. But, your master exchanged his war merits for this, so you can only choose one."
Taking out the Scroll of Seals, Jiraiya showed it off to Minato with a smug look.
Minato was genuinely stunned. He hadn't expected Jiraiya's gift yesterday to be the Scroll of Seals. Even having watched Naruto, he knew how strict the conditions were to even look at the scroll.
For Jiraiya to go to such lengths, it was clear he had put a lot of thought into it.
"Master, thank you." This time, Minato's thanks were sincere. Although this guy was unreliable, he really did his best for him.
"You brat, it's not easy to hear a proper 'Master' from your mouth," Jiraiya exclaimed, striking an ugly pose that was truly an eyesore.
"Pervy Toad, hurry up and stop wasting time." Seeing Jiraiya's antics, Minato was speechless. Calling him Pervy Toad really was the right choice.
Jiraiya's flamboyant dance froze, and a large drop of sweat trickled down his head.
Snatching the Scroll of Seals from Jiraiya's hands, Minato opened it. He had already made his choice before even looking at it.
He had been wondering how to get his hands on his signature ninjutsu, and then Jiraiya had delivered it so readily.
He pretended to browse through it for a while before finally selecting the Flying Thunder God Technique.
"Pervy Toad, I choose this jutsu." Pointing to the Flying Thunder God Technique, Minato said with determination.
"The Flying Thunder God Technique? That's a space-time ninjutsu. Only the Second Hokage could use it. Many Konoha ninja have chosen it, but they all failed. This technique is extremely difficult. Do you want to pick another one?" Jiraiya explained after seeing Minato's choice.
"No need. I feel this is the most suitable ninjutsu for me." Minato shook his head, rejecting Jiraiya's suggestion and sticking with his choice.
"Alright then. Perhaps with your talent, you can really reproduce the Flying Thunder God Technique." Seeing Minato's determination, Jiraiya didn't try to persuade him further. It was his disciple's choice; as a master, he only needed to offer guidance.
Minato then carefully read everything related to the Flying Thunder God Technique. After he finished reading...
"Ding! Congratulations on learning the Flying Thunder God Technique. Space development has been unlocked. Current level: 1%. Please continue to develop it, Host."
As expected, he automatically learned the skill after reading it, and now all he needed to do was develop it. Hearing the system prompt in his mind, Minato thought to himself.
This was another one of the system's overpowered features.
Now, he could focus on developing his space abilities for the next year.
Because he had seen the power of space after its evolution, it was incredibly strong. So, he would now mainly focus on developing his space attribute.
After pretending to read for half a day, Minato closed the Scroll of Seals and handed it to Jiraiya.
"You're done already? Don't be in such a hurry. You have until tomorrow morning," Jiraiya advised, as it had only been half a day.
"I've completely understood it and memorized it. Looking at it any longer would just be a waste of time," Minato said, shaking his head. He then told Jiraiya he was going to practice.
At his usual training spot, he recalled the requirements of the Flying Thunder God Technique from his mind and carved the Flying Thunder God formula.
Then, he walked 10 meters away and carved another formula. With a thought, he activated his chakra.
"Swoosh!"
Minato vanished from his spot and reappeared where he had just carved the formula.
"Success! With this god-tier system, my life is set! In this life, I will definitely reach the pinnacle of the ninja world, punching Madara of the Six Paths and kicking Kaguya!"
Minato exclaimed in excitement after successfully using the Flying Thunder God Technique. However, the chakra consumption was a bit high; it used up one-tenth of his chakra. With Minato's current chakra reserves, he could only use it ten times.
It was important to note that Minato's chakra reserves were much higher than his power level would suggest. The average elite Chunin didn't have as much.
This was because his chakra had doubled when his physique development reached 60%, and then tripled when it reached 80%.
This showed just how much chakra the Flying Thunder God Technique consumed.
Minato was excited, but two other people were terrified: Hiruzen Sarutobi and Jiraiya.
The two of them were in the Hokage's office, staring wide-eyed at each other, looking at the image of Minato using the Flying Thunder God Technique in the crystal ball with utter shock.
"Are you sure he just saw the Flying Thunder God Technique today?" Hiruzen Sarutobi asked, his words jumbled.
"You're the one who gave me the Scroll of Seals this morning," Jiraiya replied, rolling his eyes in annoyance.
"Is Minato's talent really that terrifying?" Hiruzen Sarutobi stared intently at Jiraiya.
