Within the Dragon Vein, Naruto glanced at the Three Tomoe Sharingan soaking in the potion in his hand.
Without paying it much attention, he casually set it aside and continued to study the Dragon Vein's seal.
At this moment, Naruto had already memorized the technique used to seal the Dragon Vein, including his father's Flying Thunder God Seal, and began to study why this combination could achieve interdimensional travel.
To this day, Naruto's understanding of space Ninjutsu had reached a very high level.
After all, years of research into the Flying Thunder God Technique and Sealing Technique were not in vain.
After carefully studying it for three days, Naruto discovered the truth behind this technique combination that could travel through time and space.
"Is brute force a universally applicable rule in the universe?"
Looking at the Dragon Vein's sealing technique before him, Naruto stroked his chin, his expression a bit strange.
Through analysis, Naruto discovered that there was nothing special about this sealing technique. It was just a sealing technique to prevent energy leakage and absorb energy to maintain its own existence.
Within the entire sealing structure, the only thing related to space was the Sword of Shinobi Love engraved with his father, Minato Namikaze's, Flying Thunder God Seal.
From this, Naruto came to a conclusion.
The only reason such a technique combination could achieve time-space travel was brute force!
At the moment of tearing the seal, a massive amount of Dragon Vein energy surged out, using the spatial power attached to the Flying Thunder God Seal as a guide to pierce through space, forming a spatial channel that could transport people to other worlds.
The reason it was traveling to an adjacent parallel world might be because the two worlds were relatively close, or it might be because there was another Dragon Vein's energy attracting it, or it might be because the Flying Thunder God Seals of Minato Namikaze in different worlds resonated.
And the energy of this Dragon Vein was not infinite. Although Naruto observed that it could convert Natural Energy to recover, excessive exploitation could lead to depletion.
"So, is the existence of this Dragon Vein a leakage of planetary energy, or is it similar to the Dragon Veins mentioned in cultivation novels?"
"Roughly estimating the energy intensity of this Dragon Vein, if Kurama and I accumulated ten years of Chakra and released it using this technique in a short period, we could achieve the same effect."
"If Sasuke and Boruto really traveled here, then the energy consumption of their time machine was obviously not very large, definitely not reaching the current intensity, probably not even one ten-thousandth of the energy."
"This shows that there are more efficient and direct methods of traveling between worlds, but it belongs to a very high technological category. If I use this crude, brute-force time-space travel device for research, I don't know how long it will take to achieve."
"Should I try to activate the Dragon Vein to travel through time and space? Or use this vast Dragon Vein energy for something else?"
Naruto couldn't help but fall into deep thought.
"This Dragon Vein energy can be directly absorbed and converted into my own Chakra. Although the conversion rate is not high, it has the advantage of being large in quantity. If I can find a way to store this energy, I might be able to launch Rinne Rebirth without loss."
"In addition to this, I can also use Sealing Technique to develop Chakra weapons with this Dragon Vein energy..."
Before Naruto could figure anything out.
He heard Kurama's excited voice in his ear: "Naruto, in the eastern forest of Konoha, there is an extremely large Chakra reaction. I sensed it, it's Pupil Power from the Rinnegan, very similar to the old man's!"
...
In the forest, Sasuke Uchiha, who was now thirty-three years old, with obvious weight gain in his cheeks and body, and somewhat kidney-deficient, his handsomeness clearly not as good as when he was a teenager, brought his disciple, Uzumaki Boruto, to the past era.
According to history, the Chunin Exam and the Konoha Crush Plan had just ended at this time.
Hidden Leaf Village welcomed back their Fifth Hokage, Tsunade, the granddaughter of the First Hokage.
Not long ago, the last survivor of the Uchiha clan, Sasuke Uchiha, a Genin, defected from Hidden Leaf Village and went to Orochimaru, a S-rank Rogue Ninja from Hidden Leaf Village, without hesitation.
He wanted to gain power and seek revenge on his brother, Itachi.
And Naruto, as his best friend, was about to go on a training journey with Jiraiya, one of the Three Ninja, vowing to bring Sasuke back after becoming stronger.
"Ouch."
Boruto landed in this era face-first.
If it weren't for his strong physique, anyone else would have been killed by such a fall.
Sasuke, the uncle, stood in place for a few seconds, covered his eyes, and suddenly knelt on the ground, weakly saying, "Ah, my Chakra is exhausted!"
As expected of Kakashi's direct disciple, the one who took on most of the bed scenes in the entire Hokage series, he opened his mouth and said his master Kakashi's classic line.
Like master, like student!
"Are you okay?"
Boruto asked his master uncle, and then looked around, "Where is this? There's no sign of Urashiki!"
"It seems necessary to investigate." Uncle Sasuke stood up and said.
Then, the two stood up, left the forest, and arrived in the Hidden Leaf Village's city.
Standing on the water tank, Uncle Sasuke came to a shocking conclusion, "This is the Hidden Leaf Village of the past!"
"There are so few Hokage Rock faces, Dad's is gone, Kakashi-uncle and Tsunade-granny's Hokage Rock faces are gone! And there's no New Shopping District, many streets are gone!"
Boruto also exclaimed in shock.
Obviously, no one can remain calm about time travel.
Naruto, who had used the Flying Thunder God Technique to fly over in advance and activated optical camouflage, listened to the two people's dialogue, which was exactly the same as in the anime, and finally confirmed one thing: these two were indeed from the Boruto era.
If nothing unexpected happened, three days later would be the time when Urashiki would arrive.
Looking at Uncle Sasuke, who looked like he had kidney deficiency and hadn't even noticed him nearby, Naruto felt that he probably didn't need to panic.
According to combat power calculations, that Urashiki shouldn't be a match, and he could take him on alone without any problem.
Of course, detailed information needed to be confirmed later.
And now, Naruto could finally do something he had wanted to do for a long time.
He unhesitatingly swung the Sword of Shinobi Love and directly punched Boruto, who was shocked by the time travel, on the head.
The huge force directly created a visible bump on this silly son's head.
"Ouch." Boruto screamed in pain.
"Who."
Then, Sasuke, as an expert, reacted and subconsciously wanted to throw a Shuriken over.
But as soon as his eyes turned, his expression froze.
Then, Uncle Sasuke saw a familiar yet unfamiliar young man standing behind Boruto.
Seeing the way he had just retracted his hand, there was no doubt that he was the one who had thrown that punch.
"Dad hitting son, oh well, nothing to see here..."
