Let the ninja world begin to tremble!

Chapter 1: System

Konoha Year 51, Summer.

Hidden Leaf Village.

A courtyard within the Uchiha clan grounds.

"Open system!"

On the retinas of Uchiha Genya's eyes, a pale blue virtual screen appeared, displaying information.

Host: Uchiha Genya
Gender: Male.
Age: 6.
Appearance: Very high.
Faction: Uchiha.
Ninjutsu: Transformation Technique, Clone Technique, Substitution Technique, Chakra Extraction Technique.
Bloodline Limit: Sharingan Lv1 (7/100,000), Sage Body Lv1 (9/100,000), Wood Style Lv0 (19,720/20,000).
Chakra Volume: 500/500 (Average Genin 200).
Chakra Reserve: 1,500 (Can store 3 times the host's own chakra).

"Use 300 points of chakra to exchange for Wood Style energy."

"Energy +300, Wood Style Lv0 (19,720/20,000) → Wood Style Lv1 (20/100,000)."

"Ding! Congratulations to the host for upgrading Wood Style to Lv1."

"Ding! Congratulations to the host for obtaining ninjutsu: Wood Style: Cutting Technique, Wood Style: Strangulation Technique."

Uchiha Genya clenched his fists, a smile tugging at the corners of his mouth as he said excitedly, "Wood Style has finally reached Lv1!"

"Just as the system description stated, upgrading Wood Style grants corresponding Wood Style ninjutsu!"

Genya was originally a 996 corporate slave on the Blue Planet. Over a year ago, he accidentally transmigrated into the world of Naruto and became a member of the Uchiha clan.

The timeline of his transmigration was Konoha Year 50, the year of the Nine-Tails' attack. Fortunately, Genya was a Naruto fan and had anticipated the danger, surviving that natural disaster.

At the same time, his super-strong adaptability allowed him to quickly get used to life in the ninja world and integrate into it.

However, due to the brutal Third Shinobi World War, his parents sacrificed themselves on the battlefield to protect the village, and Genya became an orphan.

But luckily, Genya obtained the standard system for transmigrators and received the Sage Body from it.

In Genya's impression, only the Sage of Six Paths, Asura, and Hashirama Senju possessed a true Sage Body.

The Sage Body is not a bloodline limit, yet it is more terrifying than many bloodline limits, similar to the bloodlines found in fantasy novels.

Upon awakening the Sage Body, the cells in the body possess terrifying vitality, capable of infinite division and regeneration, granting the host vigorous life force and peerless chakra.

The First Hokage, Hashirama Senju, possessed chakra comparable to a Tailed Beast and was hailed by Madara Uchiha as a warrior who could not be killed on the battlefield.

Some people joke that while both awakened Wood Style, Yamato's Wood Style is for landscaping, while Hashirama's Wood Style conquers the world.

This remark is full of mockery, yet it is also the truth.

What is strong is not Wood Style.

It is Hashirama Senju, who possesses the Sage Body.

Genya is the fourth ninja to truly possess a Sage Body!

Beyond that.

Genya also "accidentally" awakened the Wood Style bloodline limit, and he can convert chakra into energy at a 1:1 ratio to upgrade his three bloodline limits.

Each time a bloodline limit level increases, he gains corresponding abilities.

For instance, the Sage Body improves physical fitness and increases chakra reserves.

The Sharingan grants ocular power upon awakening.

Wood Style grants access to secret Wood Style techniques.

Within the clan, children aged four to five are taught chakra extraction by an introductory instructor.

Genya could be called a prodigy; he learned chakra extraction in less than a day and mastered the Three Basic Techniques along the way.

After more than a year of hard work.

Genya first upgraded his Sage Body, then his Sharingan, and finally his Wood Style.

There is a reason for this upgrade order.

Before the Sage Body was upgraded, Genya's chakra reserves were only 200; after reaching level 1, they rose to 500, more than doubling.

With the increase in chakra, the upgrade speed of his other two bloodlines also improved significantly.

Next to be upgraded was the Sharingan, and finally, Wood Style.

After the First Hokage, Hashirama Senju, passed away, the Third Hokage, Sarutobi Hiruzen, and Orochimaru both secretly researched Wood Style, and Yamato was even a test subject for it.

Genya was well aware that if it became known he possessed the Wood Style bloodline, it would cause a massive uproar in the village. His ultimate fate would likely be imprisonment in a dark dungeon by the Konoha high command, or perhaps even being sent to Orochimaru's laboratory.

Therefore, while Wood Style is undeniably powerful, its priority was set to the very end, and it could only be used as a trump card; it must not be exposed unless it is a matter of life and death.

Moreover, in the original story, upgrading the Sharingan to the Eternal Mangekyo Sharingan requires transplanting the eyes of a close relative, but now he could upgrade his Sharingan to the Eternal Mangekyo directly using chakra.

He just had to grind for it!

After all, he was an orphan and had no eyes of close relatives to use for upgrades.

Even if he did, he would never do such a thing for the sake of power.

This was his personal code of conduct!

"Let's test the power of Wood Style!" After the Wood Style level increased, he gained "Wood Style: Cutting Technique" and "Wood Style: Strangulation Technique," and Genya wanted to test their power.

His residence was located in a remote corner on the northwest side of the Uchiha clan grounds, so he didn't have to worry about anyone discovering him.

"It's a good thing that old pervert, the Third Hokage, can't peek at me!" Genya whispered to himself.

Sarutobi Hiruzen possessed a crystal ball and could use the Telescope Technique to observe every corner of the village, but the prerequisite for this was that he had to have imprinted the target's chakra beforehand. Genya had never performed ninjutsu in front of him, so the man could not see him.

The two Wood Style secret techniques gifted by the system were already deeply etched in his mind.

Genya mobilized the chakra in his body and quickly formed hand seals to perform the ninjutsu.

"Wood Style: Strangulation Technique!"

"Whoosh, whoosh, whoosh!"

Seven or eight thick branches burst out from the ground.

Under Genya's control, the branches moved like agile pythons, rapidly coiling around a massive boulder.

These stones were what Genya used for his physical training.

"Put your back into it!" Genya shouted in a low voice!

The trees were seen winding tighter and tighter.

Cracks began to appear on the boulder with a series of snapping sounds.

The power of Wood Style was immense!

If an ordinary genin were caught in this, they might have already been strangled to death.

"Wood Style: Cutting Technique."

A sharp wooden spike grew rapidly from the palm of Genya's right hand.

He lunged forward with force, and with a "shing" sound, the hard rock was instantly pierced.

Then, Genya formed another seal, and using the first spike as a base, seven or eight more spikes instantly shot out in all directions.

The rock was instantly turned into a pincushion!

"Wood Style combined with the Sage Body is truly strong!" Genya sighed softly, while also looking forward to what kind of secret technique he would gain when he next upgraded Wood Style!

"It's just that the chakra consumption is quite high." Genya gave a bitter smile; performing two ninjutsu had consumed a significant amount of his chakra. Increasing the level of his Sage Body remained the top priority.

The training session ended.

Genya put away his Wood Style and began to clean up.

Not long after he finished tidying up.

A "bang, bang, bang" knocking sound came from his ears.

"Coming." Genya frowned, walked to the courtyard to open the door, and upon seeing who it was, asked in surprise.

"A rare guest indeed, what brings you here?"

A boy of about six years old stood outside the door, with faint tear troughs on his face, dressed in the clan uniform bearing the Uchiha clan's fan crest.

Itachi Uchiha!

At this moment, Itachi lacked the maturity and the air of wisdom—the sense that everything was under his control—that he would possess as an adult; he looked slightly green.

He even seemed a little... cocky?

Itachi glanced indifferently at Genya and said, "Father told me to call you over for dinner."

Genya's father had been a jonin and a close friend of Fugaku Uchiha; the two had braved life and death together on the battlefield.

Ever since his parents sacrificed themselves, Fugaku had taken great care of Genya, and due to the friendship between their elders, Genya and Itachi had become friends as well.

"Oh!"

"Bang!"

The door was slammed shut, leaving a bewildered Itachi behind.

???

Less than a minute later, Genya opened the wooden door with a smile and stepped out from the courtyard.

Looking at the oversized food container in Genya's hands, black lines sprouted on Itachi's forehead as he said with slight irritation, "It's one thing that you come over for dinner every time, but what's the meaning of packing leftovers to take home?"

Genya's words were laced with a hint of mockery.

"Are you actually unaware that diligence and frugality are the fine virtues of the Hidden Leaf Village?"

"What a spoiled rich kid!"

In truth, every time he went to eat at Fugaku's house, Mikoto Uchiha would intentionally cook extra ingredients so that Genya could pack them up for his own dinner, showing great care for the boy.

As time went on.

Itachi, who often pondered the meaning of life, would also get jealous. He would occasionally mock Genya, but he was always retorted by Genya, whose mouth seemed to have been blessed by the gods.
