The 50th year of Konoha was a very important year in the entire history of Naruto, with many major events occurring, such as the end of the Third Great Ninja War, the famous Battle of Kikyo Pass, the Battle of Kannabi Bridge, and the Third Raikage being exhausted to death by thousands of Iwa ninjas.
However, in terms of impact on later generations, none of these events were as significant as the death of one woman: Rin Nohara, Uchiha Obito's secret crush.
It was precisely this woman's death that caused Obito to turn to darkness, transforming him into a demon who killed his teacher, his clan, and innocent people. The fact that such a person could be redeemed in the end is truly disgusting.
Of course, none of this has happened yet, or perhaps it is happening right now. In any case, for Ling Yun, these things don't matter. After all, at only five years old, he can't even defeat a genin without ninja tools, so even if he wanted to intervene, he wouldn't have the ability.
Suzuki Ryoko was eventually convinced by Ling Yun and took the optimized storage spell seal to Hiruzen Sarutobi.
Although Hiruzen Sarutobi was not the strongest Hokage, his nickname "Professor of Shinobi" was quite fitting.
He not only knew five types of ninjutsu but was also proficient in sealing jutsu, so he immediately recognized the immense value of optimizing this sealing spell.
"Ryoko, well done! I've long known you had extraordinary talent in sealing jutsu, and now it has indeed come to fruition. This optimization not only lowers the threshold for creating storage scrolls but also greatly saves costs. It's truly a huge contribution."
Hiruzen Sarutobi held the storage spell seal Ling Yun had drawn and personally experimented with it several times, his old face almost beaming with joy.
"Are you really going to contribute this technique?"
Suzuki Ryoko knelt on one knee.
"Lord Hokage, as a Konoha ninja, I am willing to do anything for Konoha. If the optimization of the storage spell seal can lead to better development for the village, it would be my honor."
"Haha, you truly haven't disappointed me. You are indeed a successor of the Will of Fire."
Hiruzen Sarutobi was so pleased to receive such an innovative technique for free that he even stopped smoking his pipe.
At this moment, Suzuki Ryoko saw that the time was right and quickly made her request.
"Lord Hokage, I wish to read the Uzumaki clan's sealing scrolls. If I can learn more advanced sealing jutsu from them and optimize and improve them, I can certainly make an even greater contribution to the village. Please grant my request."
"The Uzumaki clan's sealing scrolls, you say? Hmm... you do indeed have exceptionally high talent in sealing jutsu. Very well, I grant your request."
Hiruzen Sarutobi quickly formed hand signs, then used a summoning jutsu to call forth the Uzumaki clan's sealing scrolls and handed them to Suzuki Ryoko.
"You have three days. Take them back and study them thoroughly. I look forward to you creating another brilliant achievement."
When Suzuki Ryoko handed the sealing scrolls to her son, Ling Yun opened them and immediately spotted a problem.
"There's no Reaper Death Seal. It seems this sealing scroll isn't complete. As expected, Hiruzen Sarutobi is still Hiruzen Sarutobi; he likes to keep a trump card."
After muttering this to himself, Ling Yun didn't pay too much attention, as it was already within his expectations.
Over the next three days, Ling Yun utilized his photographic memory to commit all the contents of the scroll to heart, and even discovered an unexpected surprise within it.
"Gravity spell! Repulsion spell!! Advanced spatial spell!!!"
"The Uzumaki clan truly lives up to its reputation as a clan as ancient as the Uchiha and Senju. They have so much knowledge stored!"
"What's wrong, son? Did you find something good?"
Suzuki Ryoko poked her head out from the kitchen, and Ling Yun quickly told her about his discovery. However, Ryoko just tilted her head.
"What's so surprising about that? High-level sealing jutsu inherently involves gravity, repulsion, and space, doesn't it? For example, defensive barriers use repulsion; otherwise, how would they repel external forces?"
"As for gravity and space, things like the Reverse Four Symbols Sealing Jutsu use both of those forces."
Suzuki Ryoko, after all, was an experienced sealing master. Although she was limited by her talent in the past and couldn't use many sealing jutsu, she had extensive knowledge.
Ling Yun, however, realized he had been mistaken, believing that gravity and repulsion were very advanced concepts and high-level sealing jutsu knowledge. Now, after his mother's explanation, he realized that these forces were actually just fundamentals, merely more advanced than the sealing spells he had learned before.
But none of that was important. What was important was that these three forces were related to several incredibly powerful ninjutsu and forbidden jutsu in Naruto.
Repulsion was the Almighty Push, while gravity was the Universal Pull, Chibaku Tensei, and so on. As for space, there were even more: Flying Thunder God, Kamui, and intangibility, among others.
It could be said that the main antagonists in the later stages of Naruto conquered the world using these three fundamental forces.
Even the final great boss, Kaguya Otsutsuki, used these fundamental forces.
"Mom, I suddenly thought of a few ninjutsu. Can you help me review them?"
With that, Ling Yun described the characteristics of Almighty Push, Universal Pull, and Chibaku Tensei.
Suzuki Ryoko listened and felt they were very powerful, especially Almighty Push, a ninjutsu with a full-range, no-blind-spot attack, which was simply the bane of ninjas.
"Most ninjas are strong in offense and weak in defense. A kunai to a vital point, even for a jonin, has a high probability of being fatal. If this Almighty Push is truly as you describe, then unless one has extremely strong defensive or regenerative abilities, any ninja who encounters it could potentially be instantly killed. But can you really create this ninjutsu using only basic repulsion spells?"
"Haha, although it's quite difficult, I think there's a good chance."
Anyone else, even Mito Uzumaki, couldn't do it. After all, although Mito Uzumaki was strong and an important figure in the Uzumaki clan, her thinking was restricted by traditional sealing jutsu. She didn't realize that sealing spells could analyze ninjutsu, or perhaps she didn't think it was necessary.
After all, using hand signs to perform ninjutsu, once proficient, allows for one ninjutsu per second, or even half a second.
In contrast, ninjutsu performed with spells was not only slow to activate but also overly complex, making it seem inferior to hand signs. Therefore, in the development process of the ninja world, spell ninjutsu gradually became obsolete, with only large-scale spells used for sealing Tailed Beasts remaining.
Ling Yun, however, was different. As a programmer in his previous life, he was very familiar with the work of program design. At the same time, he had a more long-term vision, knowing about the various incredible ninjutsu that appeared in the god-level battles during the Fourth Great Ninja War.
In other words, Ling Yun had a clear goal in mind and a complete theoretical foundation of spells. All he needed to do now was to gradually perfect the spells in his hands.
As he told Suzuki Ryoko, it was difficult, but the chances of success were high. Especially knowing the power of those few ninjutsu, Ling Yun was not lacking in motivation, which gave him even less reason to give up.
"Mom, give me another five million. I want to buy more chakra metal. I'm going all out this time!"
