Konoha.
On one side of the Technology Development Bureau, a magnificent and imposing space-time barrier rose from the ground, like a towering screen, enveloping everything around it.
Upon closer inspection, countless runes shimmering with strange light could be seen flying and intertwining in the air. They seemed to possess life, connecting and combining according to specific rules and rhythms. These runes constructed a brand new architectural structure in an extremely subtle and complex way, with every brick and every beam composed of runes.
The entire building presented a unique style, combining the simplicity and efficiency of modern technology with a profound and mysterious aura.
Its exterior lines were smooth and natural, its surface engraved with various exquisite patterns and symbols, emitting a captivating glow. From a distance, it looked like an artistic treasure from another world.
Many Ninja were watching nearby, creating a lively atmosphere.
This included the Five Kage and other well-known figures from the Ninja World.
"This is the core of the Physical Training System, everyone," Satoru introduced to them.
Raikage looked at the sci-fi-esque building: "It looks good. The technological content is very high."
It felt even more advanced than the technology in their Hidden Cloud Village.
"Is this some kind of spatial Ninjutsu?" Killer Bee also looked on curiously.
There weren't many places nearby for physical training.
Might Guy and Lee, in particular, were extremely excited.
They were the most thrilled by the establishment of this Physical Training System.
"Yes, by passing through this spatial gate, you can go to the training area. Next, I would like to invite all the Kage and physical training experts to test this system."
It wasn't entirely complete yet.
It needed to be experienced by various Ninja, both strong and weak.
Satoru was just one final step away from completion.
"Let's go, let me see your results. I'm still very much looking forward to it," Ōnoki said.
He had waited a long time.
They had provided resources, after all.
And he also wanted to see if Satoru's new training system was as powerful as the Ninjutsu Training System.
Orochimaru licked his lips beside him: "I also want to see what you can develop after I provided so many research results."
"Then let's go, we'll take a look."
Satoru placed his hand on a screen of the building, activating it with Chakra.
Below the building, a giant Chakra generator reacted, erupting with a massive amount of Chakra to power the barrier Ninjutsu above.
If anyone could see it, they would notice a large mass of White Zetsu cells on top of the Chakra generator.
A huge gate formed by a light curtain appeared as a void in the middle of the building.
On the other side of the void was a space covered in lush green grass.
Aside from the green grass and a gentle breeze, there was nothing else.
"This is the training area, an alternate dimension?"
Seeing this, Raikage guessed that the other side was probably not a place in the Ninja World.
Then he walked in.
Boom!
As soon as he stepped in, Raikage's legs buckled, and his face sagged.
His clothes ripped, and a tear appeared on his hem.
Hah!
He let out a loud shout, steadying himself.
The people outside, seeing Raikage in this state, were all shocked and looked at Satoru.
Their eyes asked, 'What's going on?'
But soon, they saw Raikage quickly adapt.
"Come on in, it's just a bit stronger gravity," Raikage turned and said to them.
Gravity?
Killer Bee was a little curious and walked in.
Then, just like Raikage, he too buckled over.
"Bee, this is Kaguya's space," at that moment, Eight-Tails' voice came to Killer Bee's ear.
"Kaguya's space?" Killer Bee was curious.
Eight-Tails: "Hmm, I remember this place. It's Kaguya's space. Satoru must have done something here, coming here through a space-time barrier."
He had an impression of this place.
The others also walked in one after another.
Satoru also walked in.
Everyone was startled for a moment, but quickly adjusted.
After all, they were powerful Ninja, and the gravity wasn't too intense. As long as they adjusted their Chakra output, they could resist it.
"This is a gravity space, a gravity space perfectly suited for physical training.
It can comprehensively train a Ninja's stamina and strength. As long as they survive here for a period of time,
their bodies will become very strong."
Satoru introduced it to them.
"What a great place! Satoru, why didn't you say so sooner? If you had, my youth would definitely have been even more passionate!" Might Guy exclaimed.
Lee was the same: "This is great! With this place, my physical Ninjutsu will definitely become stronger!"
Then the two hugged and started crying again.
Not just them, but everyone else, feeling the gravity on their bodies, understood the effect this had on physical Ninja.
No, it had an effect on any Ninja.
That was gravity.
It could comprehensively train the body's strength.
Chōjūrō: "Training here will definitely make my swordsmanship even more powerful."
However, he was already lying on the ground.
Because his Hiramekarei was too heavy.
Kakashi: "Is that all there is?"
Then he saw a building in the distance, standing in this gravity space.
Satoru: "This gravity space is just one of the training areas, more suitable for beginners."
There was no place more suitable for physical training than a gravity space.
"What is that building?"
"That's a place for physical recovery. It uses Konoha's most advanced medical technology. After Ninja train their bodies, they can use medical technology to recover their stamina and hidden injuries, and even monitor various physical data."
Satoru introduced the functions of these buildings to them.
The main purpose was to heal hidden injuries or other damage sustained by Ninja during training.
It could also monitor physical data in real-time.
Most of the technology used was invented by the Technology Development Bureau.
Only the important technological components were completed by Orochimaru and him.
The technological content was still very high.
The personnel recruited by the Technology Development Bureau had also been put to good use.
Finally, they, the few big shots, didn't have to complete those minor technologies anymore.
One very important point was that a portion of it was developed by his son, Keigo.
At the age of six, he had such scientific research intelligence, which Satoru was very proud of.
"Impressive. And then what? Is that all? Where are those physical training data used?"
Ōnoki asked.
They, Iwagakure, could also create training environments; it was just a matter of cost.
"Come, I'll take you to see. In the future, everyone who wants to train in this Physical Training System will need to meet my requirements before they can train here."
Satoru led them to the building complex.
