The practical combat lessons ended.
Although Seimei had a lot of fun watching his classmates spar and beat each other to the ground, he needed to go home quickly.
Usually, he would just spend more time in the Academy training ground and its library, training and looking for interesting techniques and the history of the Shinobi world.
After all, this world was quite different from the original Narutoverse he remembered from his previous life.
There are still many things he didn't know.
For example, he had no idea how the Chakra Beasts came into existence. Or why increasing the amount of chakra extended a Shinobi's lifespan.
Or what would happen if he could master Sage Mode and combine his chakra with nature energy?
Would the Senjutsu chakra affect his body's vitality differently? Probably it would interact with his Otsutsuki bloodline and create some miracle.
He had many unanswered questions.
But now wasn't the time for that.
Today, he must go home early.
Uzumaki Mito or his aunt Mito had promised to give him the scrolls of Uzumaki Sealing Techniques today.
She even promised to help him with learning Fuinjutsu if he got stuck with difficult challenges during the learning process.
How could he not be excited?
This was Fuinjutsu—the Sealing Technique.
If you master it well, you could create unbreachable barriers, suppress your opponent's chakra, paralyze them, seal them, invent long-distance communication tools, and a lot more.
The explosive tags, storage scrolls, the summoning Jutsu, and many ninja equipment are the products of the Sealing Techniques.
You could use seals to reinforce walls, adjust room temperature, set traps, and even make the ground soft enough to literally jump on it and treat it like a trampoline.
Fuinjutsu seals could help you prevent eavesdropping, monitor a wide area, prevent spying, and even sense even the smallest things from far away.
There was also Juinjutsu or Cursed Sealing Technique, a branch of Fuinjutsu that used the Sealing technique to inflict various restrictions on living beings.
For example, the Caged Bird Seal of the Hyuga clan imposed severe restrictions on the Byakugan of the Branch family members.
(A/N: If those unfamiliar with Naruto, Byakugan is the unique kekkei genkai of the Hyuga clan that manifests in their eyes, similar to the Sharingan of the Uchiha clan.)
This seal made it impossible for the enemy ninjas to steal Byakugan from the Branch family members of the Hyuga clan.
Why?
That's because as soon as a Branch family Hyuga member died or got their eyes gouged, the Caged Bird Seal would immediately act and destroy these eyes.
However, this cursed seal technique could also allow the Hyuga clan's Main family members to control the Branch family members.
Just by weaving a few secret hand seals, the Main family members could inflict terrible pain on the branch family members at will.
Unfair? Yes.
But what could they do? This world was inherently cruel.
Another example of a Juinjutsu Seal is the Self-cursing Seal.
This seal could literally restrict the movements of an enemy. However, if the enemy flared up a large amount of chakra, they could lift the restrictive effects of this cursed seal.
That was why it was best to use this cursed seal as a trap to surprise the enemy or use it alongside the Chakra Suppression Seal after defeating the enemy to capture them.
Although the Sealing Techniques weren't all-powerful, if used wisely, they could be very convenient.
Sure, in direct combat, sealing techniques might not be able to show their power.
But when it came to utility, there were only a few things that could surpass it.
Low on chakra?
Use Fuinjutsu Seals to store your own chakra before heading to the battlefield.
Iwagakure ninjas are constantly moving underground and targeting you?
No problem. Bring a Fuinjutsu Grandmaster, cast a Fuinjutsu Battlefield, and restrict your enemy's access to the natural earth. Now, they would only waste more of their chakra to cast Earth Release Ninjutsu, and they couldn't move underground.
At least, not until they broke the barrier of the Fuinjutsu Battlefield and got out of the Sealing Technique's range.
Facing a weird immortal Chakra Beast who just couldn't be killed?
Cast a Four Symbols Seal and seal them completely after defeating and weakening them to the extreme.
However, in the whole Shinobi world, Fuinjutsu experts were quite rare.
Most Shinobi didn't even bother learning Sealing Techniques.
Even if they learned them, they know very few rudimentary or necessary Fuinjutsu Seals at best.
To create even the basic Fuinjutsu Battlefield, you must be a Seal Master.
However, even the Seal Masters couldn't set up such a large-scale Sealing Technique instantly without preparing and storing the necessary seals in an additional chakra-conducting material.
Want to cast a Fuinjutsu Battlefield instantly without immense preparation time and extra baggage? Heh, become a Fuinjutsu Grandmaster first.
Only they could set up such large-scale Sealing Techniques instantly or use advanced techniques like the Four Symbols Seal or Five Elements Seal.
Unfortunately, the entire Konoha had fewer than 50 Fuinjutsu Grandmasters.
As for the other four major hidden villages, each of them didn't even have 20 Fuinjutsu Grandmasters.
That's how tough it was to become a Fuinjutsu Grandmaster.
"However, the main reason I am eager to learn Fuinjutsu is the Space-time Ninjutsu developed by my father—Flying Thunder God Technique."
"After all, it's one of the few Space-time Ninjutsu that doesn't require any ocular techniques to cast. Others can learn it too, provided they have a talent for sensing space."
"And me? I obviously have the talent."
"Who am I? I am Otsutsuki Seimei. Hypothetically, even if I have the trashiest Space-time talent among the Otsutsuki members, it would still be much higher than my father."
"Of course, that's not the case. According to my system panel, my Otsutsuki bloodline is already at Lv.5, and my other talents are just waiting to bloom as I grow up."
"Hehehe…"
"Imagine literally teleporting from one place to another almost instantly and kicking my enemy's ass before they could even react."
"Anyway, I must learn it."
Seimei talked to himself in a low voice.
Then he suddenly stopped, made a thoughtful expression, and continued his self-talk.
"To learn and use this technique perfectly, I need to become a Fuinjutsu Grandmaster."
"With my Unlimited Growth System, grinding proficiency won't be a problem."
"I can surely become a Fuinjutsu Grandmaster."
"And while I'm at it, I should also pick up other useful Sealing Techniques."
"Who knows if they will come in handy in the future?"
Seimei muttered thoughtfully as he kept walking toward his home.
His thought was simple.
To increase his combat prowess and get out of unforeseen dire situations, he must master the Flying Thunder God Technique.
Of course, he could also wait for his body to grow and eventually unlock his innate space-time ocular techniques.
However, he didn't know how long that would take.
Otsutsuki clan members could live for tens of thousands of years. And if they kept evolving, they could potentially become immortal.
So, who knows how long it would take him to unlock his own space-time techniques?
It could take ten years, a hundred years, or perhaps even a thousand.
Unfortunately, he didn't have the luxury of waiting for that to happen.
So, he set his eyes on his father, Senju Tobirama's, self-created S-rank space-time Ninjutsu—Flying Thunder God Technique.
His soul was screaming at him to learn it.
So, he thought…LET'S JUST DO IT!
Before long, he had arrived at the doorstep of his home.
It was time to have some lunch.
After that, he would dive head-first into the Uzumaki Clan Sealing Techniques.
