After resting for several minutes he made his way back to the village. Better get something to eat, sigh the seventh objective of my list of objectives will never be met at this rate. Oh well not that ramen is a bad substitute. A sated stomach and a half an hour later, Naruto reached the Konoha library. He then created 5 clones dispersing them towards each section which he prioritized earlier on. Naruto however focused on gaining knowledge on the 8 gates. 

Naruto and his clones spent a total of 2 hours; feeling that they have met their daily requirement, he then made his way back to the apartment. Urgh I smell like shit better clean myself. Refreshed, he then started organizing all the information and experiences. Reviewing each one, he could clearly see what he lacks and how he should proceed. 

Three hours later, he decided to call it day, exhausted from the day's events. As he fell asleep, several moments later, he found himself in dream world; the green vista which spans for miles, knowing no ends.

So it just happens eh? Then why the hell did that egotistic white piece of shit not say so? Urgh, my poor blood pressure and cholesterol levels. 

Sigh, I'm just gonna meditate. He however unconsciously starts absorbing the energy around him; two hours later, he notices this fact. Intriguing turn of events. Looks like I am absorbing the energy here. Wait .... this is ridiculous .... my chakra reserve has increased by 25%. Furthermore I could literally sense every fibre of my being just by a mere thought. This...

Flabbergasted, he could only attribute his changes to the strange green energy. Better gain as much out of this as I can. However 2 hours later he started experiencing an excruciating amount of pain and by 3 hours he spat out blood, damaging his interior organs. Looks like my limit is 5 hours. Better not continue unless I want to kill myself. As he withdrew, he grimaced as he stood up; he noticed he could no longer sense that strange energy. Guess I could only do that once a day. 

A few seconds later, he closed his eyes, inhaled deeply as probed his body with his mind. What he found out astounded him; his body was back to its optimal condition. Must be the doing of this dream world. Well then I got around 10 hours left, why don't I resume training the body flicker jutsu and rasengan.

The main issue with my body flicker technique is that it takes time for me to gather the chakra and then use it effectively. Currently it takes me 30 seconds to execute the jutsu. Reading the information about the chakra pathway system from the books in the library, I realize that I could change the path by which the chakra flows, though it is pretty risky. The lesser the time taken the better; the fastest reaction in the human body is a reflex action. Therefore the logical conclusion is to see whether I could carry this out through my spinal cord. After all even if I mess up, I'm pretty sure the green space could heal about any injury. Quite a useful way of experimenting really. 

Summoning a total of 1000 clones, he gave an explanation on the theoretical application of the jutsu. Afterwards, he formed a horizontal straight line with a distance of 4 meters between each clone. For the next 8 hours, Naruto and his clones were continuously looking for efficient means to cut down the time. 

Naruto closed eyes focused his chakra along the 5 tenketsu, which are the part of the spinal cord and represent the main gates. Within a fraction second he executed the body flicker technique appearing 20 meters from his starting point. Finally I succeeded, whew that was pretty intense .Once again he executed the technique this time 50 meters away. 

For the next half hour, Naruto and his clones continued to flash around. Looking at his clones successfully utilizing the jutsu, he smiled. Hahaha identifying those tenketsu really was a big help; it only takes me 1 second at most, depending on the distance. Besides my current maximum distance is 1 kilometer. Now then I get a feeling that my chakra control has increased by leaps and bounds. He turned back to his clone.

The genuine version of this novel can be found on another site. Support the author by reading it there.

"Listen up, by using the same principles I want you bunch to complete the first step in forming the rasengan" he commanded with an air authority. Little more than an hour later, Naruto and his clones completed the first step in forming the rasengan. Green sparks levitated off the surface of the dream world and within moments, a blinding flash illuminated the dream world and Naruto fell back into his slumber.

Six days later, within the dream world.....

Apparently materialising objects was possible within this realm. During the second day, Naruto wished that he had a chair to take a seat; within seconds a chair materialized out of nowhere. After experimenting with it a few times, Naruto used this factor to conjure thousands of rubber balls to help him with the second phase of the training. The main focus of that was power which could be done by increasing the density of the chakra exerted by focusing on one single point. By the end of the third day Naruto mastered the second step and by the fifth, he finally created a rasengan. It also only takes his right hand to successfully create it.

However that was not the only aspect he made progress with. The maximum distance he could travel using the body flicker technique has increased by 50% at the end of six days. Though he takes the same amount time, it still is vast improvement. His taijutsu has become more lethal and his usage of hidden weapons has become  sharper. The vast quantities of information has helped him understand the nature of chakra and the human anatomy to a new level.

However there still aspect Naruto is quite irritated about, the meditation in the the energy world. Granted that his chakra reserves are 35% more as compared to the beginning of the week, however he could only meditate for a fixed period of time and the benefits of this are decreasing exponentially. 

Sigh, I guess I cannot be too greedy. After all I have accomplished several feats that normally would not be possible. Tomorrow would be the registration date. Well then looks like my time is up. 

.........

The next day- Hokage Residence.

The third hokage looks at the form. Naruto, seated across him, with his eyes closed. Looking at the stoic expression in Naruto's face, the third Hokage could only smile in amusement.

Naruto you cheeky brat, you really have changed. Well he does seem inherit something from him. Sigh if only he did not have her temperament at times.

"Oh by the way, we are moving up the date for the team selection, you better get to your classroom fast."

"Wait why?"

"Just get going"

"Well then I am off old man later~~~"

Iruka's Classroom.

"Well then I will now recite the names of the teams."

........

"Team 8- Shino Aburame, Hinata Hyuga and Kiba Inazuma. Your instructor will be Kurenai Yuhi"

"Team 9- Shikamaru Nara, Ino Yamanaka and Choji Akimichi. Your instructor will be Asuma Sarutobi"

" Team 7- Sasuke Uchiha, Sakura Haruno and Naruto Uzumaki. Your instructor will be Kakashi Hatake."

"Now until your respective instructor/team leader arrives please do wait in this classroom."

With that, Iruka leaves the classroom and Naruto closed his eyes.

Third Hokage's residence.

The third hokage observes the classroom through his crystal ball. The surrounding ninjas all seem to be wearing the standard outfit of a Konoha Jonin. Currently they are observing the figures inside. Its is the full display of Iruka's classroom.

"So these are this year's genins huh..."

"That's the Uchiha boy isn't he?"

The third hokage continues to observe in silence along with one other man. He has distinct spiky silver hair and a mask covering the lower half of his face. 

One by one the surrounding Jonin leave to conduct their first meeting with their respective groups. Yet the masked man remains standing. 

"Take care of them. Especially those two, Kakashi."

"Yes Lord Hokage."
