Naruto: Inheriting the Legacy of a Person Who Traveled Through Time

Genjutsu is essentially a ninjutsu that creates illusions by interfering with the opponent's five senses through chakra, or it can be used to achieve mental attacks by manipulating the flow of chakra in the brain's nerves. It is one of the three basic skills of a ninja.

However, compared to ninjutsu and taijutsu, genjutsu requires a relatively high level of skill from the user, so most ninjas use genjutsu as a supplementary tool. Apart from learning how to break genjutsu attacks, they rarely study it in depth.

The reason for this is that casting illusions is quite dangerous. Once you encounter an opponent whose mental strength surpasses your own, not only will you waste your chakra in vain, but you will also easily suffer a backlash that puts you in danger. If you are not careful, you will fall into an embarrassing situation where you are at the mercy of your enemy.

The most classic example is Kurenai Yuhi. A newly promoted Jonin dared to use genjutsu on Itachi Uchiha and was immediately taught a lesson that made her doubt her life. She completely forgot that the Uchiha clan was once famous in the ninja world for its fire release and genjutsu. In the end, she became a background to highlight the power of the Sharingan.

Just fifteen minutes later, Kakashi, who was leaning against a tree trunk and watching the Icha Icha Paradise with great interest, looked up in surprise and noticed a change in the flow of chakra in Tetsuya not far away.

"Thank you, Jonin Kakashi."

Tetsuya, in high spirits after successfully executing the Naraku Sight Technique, handed the scroll in his hand to Kakashi.

Tetsuya read the scroll twice, and the contents were firmly memorized. Moreover, he succeeded on his first attempt at casting it, confirming that his talent had indeed been qualitatively improved.

Even when they were learning the Three Body Techniques at the Ninja Academy, they didn't have it this easy, which is enough to prove once again the value of the Uchiha bloodline.

"Try using it on me once."

Kakashi took the scroll, a hint of surprise in his eyes, and spoke.

Although the Naraku Sight Technique is only a D-rank technique, compared to ninjutsu which only requires chakra, genjutsu requires additional mental energy, making it a level more difficult. Kakashi was completely surprised that Tetsuya was able to learn it in such a short time.

"I'm sorry."

Che also apologized, and his chakra, mixed with spiritual power, surged out, enveloping Kakashi, who was half a zhang away, in a subtle and gentle way.

Kakashi, who was determined to verify the completeness of this illusion, did not deliberately defend himself, allowing the invisible threads to penetrate his body.

"Kakashi, kill me!"

In an instant, Kakashi felt as if he were back in the Third Shinobi World War, when the girl with paint on her face staggered towards him, tears streaming down her face, and that unforgettable shout.

Lin, I'm sorry!

Seeing his former comrades, Kakashi knew that everything before him was just an illusion, but he still felt the urge to cry.

"Kakashi, why did you break your promise to me?!"

Before Kakashi could disrupt his chakra flow to break the genjutsu, another figure appeared beside Rin Haruno. Although half of the other person's body was a bloody mess and the other half of their face had empty eye sockets with blood flowing out, Kakashi still recognized them at a glance.

Uchiha Obito!

As expected, Obito will never forgive me.

Sweating profusely, Kakashi lowered his head, unable to look directly at the two figures that were getting closer and closer.

In an attempt to escape the scene that kept recurring in his nightmares, Kakashi's three-tomoe Sharingan, hidden by his headband, trembled slightly as he subconsciously unleashed the genjutsu: Mirror Heaven and Earth.

This is a relatively rare type of illusion that can not only break the illusion cast by the enemy, but also reflect the illusion effect back to the caster.

Oh no, can that genin withstand the rebound of the genjutsu?

As the scene before him crumbled, Kakashi couldn't help but feel a pang of regret.

Even though it's just the lowest level of genjutsu, with Kakashi almost uncontrollably activating the Sharingan's power to amplify and rebound it, it shouldn't cause serious mental damage, right?

"Kakashi, Jonin, are you alright?"

When Kakashi's vision returned to the real world, he immediately heard Tetsuya's voice. The other man was standing about half a meter away, with a concerned look on his face.

"……fine."

Kakashi wiped the sweat from his forehead, his eyes filled with surprise.

Surprisingly, they didn't fall into the illusion created by the illusion rebound?

Could it be that the opponent's genjutsu talent is comparable to that of a genjutsu jonin like Kurenai Yuhi?

"Thank you, Jonin Kakashi, for the ninjutsu scroll."

Having unexpectedly obtained an illusion technique, Tetsuya was in a good mood. After thanking Kakashi again, he turned around and prepared to leave.

As a low-ranking ninja who was just cannon fodder, Tetsuya knew how difficult it was to acquire a ninjutsu, and his words of thanks were full of sincerity.

"Illusion Technique: Nirvana Abode Technique!"

As he watched Tetsuya walk away, Kakashi suddenly formed hand seals, and palm-sized feathers began to fall from the sky, instantly covering a distance of seven or eight zhang.

This is a wide-ranging A-rank illusion. Anyone who sees the feather phantom will fall into a deep sleep. However, because the power is relatively dispersed, any genin with strong mental strength can immediately realize they are trapped in the illusion and then calmly break free.

Kakashi suddenly used this technique to test the limits of Tetsuya's genjutsu talent.

However, to Kakashi's surprise, Tetsuya's steps never faltered, even though he was within the genjutsu's range. His chakra remained normal as he stepped across the river, escaping the genjutsu's range. He picked up the two bags on the other side and quickly disappeared from Kakashi's sight.

The illusion is ineffective?

Kakashi's eyes narrowed suddenly, and he made a mental note of it.

Once the mission is over and we get back, let's check the other party's information.

-----------------

Behind the Hokage Building, Kakashi flipped through numerous files and quickly found Tetsuya's ninja file card.

Tetsuya's parents were both commoners born and raised in Konoha, and they passed away one after the other three years ago. His performance after entering the Ninja Academy was rather mediocre. Whether it was his theoretical grades or his practical performance, he was no better than the other commoner ninjas. He was not qualified to enter Class A that year and was a typical cannon fodder ninja.

After graduation, he was assigned to a squad led by a Chunin. After completing more than ten D-rank missions in an orderly manner, he encountered an accident on his only mission outside the village. The Chunin leading the squad and his comrades were either killed or injured, leaving him all alone.

The only evaluation from the ninja academy teachers was that Tetsuya trained diligently, but his talent limited him and the results were meager. The best outcome for him in this life was to continue his training step by step and he would have the potential to become a Chunin after adulthood.

Kakashi closed the file and put it back in its place, a thoughtful look in his eyes.

The curriculum at the Ninja Academy is very broad, and the graduation exam is only randomly selected from the Three Body Techniques, so it's not surprising that Tetsuya's talent for genjutsu couldn't be discovered.

If Tetsuya could focus on training in illusion techniques, perhaps he would have a chance to become a special jonin in the future?

Seize, seize, seize!

Kakashi had just opened the door to the files room when he heard the sound of a cane hitting the ground, and his expression immediately darkened.

At the end of the corridor, an elderly man with bandages wrapped around his forehead and right eye walked slowly towards the Hokage's office.

Danzo Shimura, a member of the Konoha Elder Council and leader of Root!
