Yellow Flash?

Naruto picked up the admission notice from the table and skimmed through it. He saw that there was less than a month left before he started school.

Thinking about school, Naruto couldn't help but recall how he used to carry his schoolbag back in his previous life. It was a pity that, without his parents around in this life, no one would be there to send him to school.

But it wasn't a big deal.

At least he still had a big fox!

"Is it finally time to become a ninja?"

"I'm starting to look forward to it!"

For the past six years, Naruto had maintained a reasonable exercise routine. He would jog for half an hour, practice horse stances, and use every exercise method he knew from his previous life.

But he didn't dare to push himself too hard. After all, he was only six years old, and there was a concern that excessive exercise might hinder his growth.

Unfortunately, despite these years, Naruto hadn't yet had the opportunity to come into contact with Chakra. He was too afraid to ask the Third Hokage about it, worried it might raise suspicion.

As for the fox inside him...

Naruto figured Kurama probably knew about Chakra refinement. But asking the fox directly? That seemed risky. Kurama had a tendency to be as troublesome as the big orange he had raised in his previous life. The fox's tsundere temperament made things tricky.

Going to Ninja School was Naruto's only chance to get close to Chakra.

Returning to the sink, Naruto carefully washed the dishes, then headed to his closet to pull out a set of black clothes. He had maintained the style of his previous life, preferring simplicity. His wardrobe consisted mainly of black and white garments.

Looking at himself in the mirror, Naruto saw a version of himself quite different from the Naruto in the original story. For convenience, he kept his hair short, similar to the Seventh Hokage. And he was notably taller than the Naruto of the original story.

Naruto mused that he was about the same height as Sasuke, though Sasuke had always been taller in the original series. The difference seemed to be due to long-term malnutrition, which led Naruto to silently grumble about the Third Hokage.

Without the system, he would have had to rely on the meager amounts of food provided by the Third Hokage. If he had to depend solely on that, he'd probably be in even worse shape than the Naruto from the original story.

Putting on his mask, Naruto glanced at the clock—it was already half-past eight in the evening.

He nodded slightly, donned his mask, and began his after-dinner exercise routine.

Late at night in Konoha Village, the streets were deserted. Only the streetlights and the moths surrounding them accompanied Naruto. The village was as brightly lit as ever, with a lively nightlife. However, after eight o'clock, most people turned off their lights and went to bed.

Naruto preferred to go out during these quiet hours. The Third Hokage's rumors about him being the Nine-Tails' reincarnation had become almost like a fairy tale to scare children, as Naruto rarely made public appearances. As a result, many people began to doubt the validity of these rumors.

Standing outside at night, Naruto knew that the villagers might not recognize him. The rumors had faded because he kept to the shadows.

After jogging for about half an hour, Naruto returned home, took a shower, and went to bed. His consciousness then drifted to the sealed space.

Upon entering, he saw Kurama sprawled out, with his forelimbs resting on his head. Naruto walked to the open space in front of the villa, measured the distance, and took out a space door.

Kurama's eyes fluttered open slightly, intrigued by what Naruto was up to. It seemed like he was still pretending to be asleep.

The moment the space door was opened, a large purple cocoon quickly formed on the ground, glowing with a purple light.

Naruto looked at the space door and swallowed nervously. It was his first time using it, and he was a bit apprehensive. But thinking about the safety of the sealed space, he figured that if something went wrong, he would simply be expelled from it.

Taking a deep breath, he closed his eyes, gritted his teeth, and dived into the cocoon of purple light.

The next moment, he appeared on the edge of a golden wheat field, having successfully used the space door.

"Yes! It worked!" Naruto exclaimed, jumping up and waving his fists in triumph.

He had successfully transported himself to the location he had in mind. This suggested that as long as he could picture a place, he could use the space door to reach it.

Wasn't this like a form of space-time Ninjutsu?

Encouraged by the success, Naruto began experimenting with the space doors, pushing their limits. Kurama watched in amazement.

What kind of strange ability did this kid have?

In the sealed space, Naruto kept flickering between locations—sometimes by the river, other times by the orchard. The purple light flashed with every appearance.

Later, for the thrill of it, Naruto even teleported into the air, using the space door to control his descent and repeating the process.

Kurama's head spun. While Minato was known for his time-space Ninjutsu, Naruto's purple light cocoon seemed like something entirely different. It didn't emit any Chakra fluctuations.

How was this possible?

Kurama was baffled, genuinely unable to figure out the mechanics behind Naruto's abilities.

After about a hundred uses of the space door, Naruto felt exhausted.

"I thought there was no consumption at all..." he muttered, noting the system's cooldown and his drained state. The small blue bar under his experience bar was empty, suggesting he'd have to wait until the next day to continue.

Feeling tired from all the experimentation, Naruto took out a large piece of magic dragon meat and placed it on the barbecue grill. The meat was the size of a washbasin, and since it was a magical creature, it had properties that could replenish both magic and spiritual power.

He skewered the steak with an iron rod, lit the charcoal fire, and added cumin, chili powder, and barbecue sauce. Soon, the delicious aroma filled the sealed space.

Kurama, having caught the scent, couldn't help but feel a pang of hunger. The smell reminded him of the raw meat he had tasted before. It was enough to make him want to cry.

As Naruto rolled the barbecue, Kurama stared intently, his mouth watering, as if he might get a chance to taste the delicious meat.

Finally, Kurama couldn't hold back any longer.

"Kid...you..." Kurama began, feeling a bit embarrassed to ask directly about the meat. Instead, he decided to inquire about the space doors.

"What was that time-space Ninjutsu you used earlier?"
