Classic Rasengan

"We really do have to go to the battlefield, but... I wouldn't be much help if I went. You know I've been studying nonstop lately, Second Brother. It's all to improve my strength."

After Uchiha Gen finished speaking, he looked at Izuna. Seeing that he had taken it in, Gen inwardly breathed a sigh of relief and added:

"Besides, I'm preparing to develop a hand-signless ninjutsu. I've only just found a lead, and if I go to the battlefield, who knows whether I'll still find that inspiration when I return? How about... I go next time instead?"

Izuna folded his arms and considered it. His third brother did have a point. Moreover, he had only just begun learning Chakra transformations, yet he had already found inspiration for a hand-signless ninjutsu. Such an opportunity was indeed hard to come by.

"Then... then you have to go next time, okay? Otherwise, it'll be hard to explain things to Father."

"Definitely! I'll definitely go next time!"

After finally sending his second brother Izuna away, Uchiha Gen soothed his poor little heart.

He had never expected his clansmen to tattle on him. Seriously...

But when he remembered that he was the clan head's son, it no longer seemed strange. The Uchiha were simply that kind of clan, exceptionally fond of battle.

"Looks like I won't be able to avoid it next time. It hasn't even been a month, and this is already the third time, right?"

What was there even to fight about? They could fight all they wanted and still couldn't do anything to the other side. Why not just develop properly and crush them head-on?

Uchiha Gen felt somewhat anxious. He wandered through the clan alone, watching those clansmen packing their things and preparing for battle as he frowned in thought.

This time, the commotion was rather large. Even those whose injuries were only half-healed had been mobilized, leaving a large stretch of the injured quarters suddenly empty.

Aside from the elderly and young, this fight had nearly emptied out eighty percent of the Uchiha's able-bodied fighting force.

"This is quite a spectacle. Who are they fighting?"

After giving it some thought, he understood. Other than the Senju, who else could warrant such a grand deployment?

More than a thousand Uchiha had been dispatched at once, including as many as seventy or eighty Jōnin.

"As expected of a major clan. They actually have so many Jōnin."

Many of the faces were unfamiliar to him, and he could not even name some of them.

Several clansmen passed by Uchiha Gen, letting out incomprehensible cold snorts that left him utterly bewildered.

"Why are you snorting at me? Lunatics."

Uchiha Gen muttered quietly before turning to leave. He had not forgotten the hand-signless ninjutsu he had bragged about to his second brother earlier.

When it came to the most famous hand-signless ninjutsu, it was undoubtedly the Rasengan, also one of the essential techniques every transmigrator had to learn.

The Uchiha Training Ground had returned to its empty state.

"I remember needing rubber balls, right? But this era probably doesn't have any."

The principle of the Rasengan was to form an energy sphere of irregularly rotating Chakra in one's palm.

The protagonist Naruto had gradually learned it by progressing from balloons to rubber balls, but this technique was brutal on the hand.

Because every force had an equal reaction, using it even once would inflict serious damage on the cells in one's arm and palm.

"My Chakra control can now be considered fairly accomplished. Although I've only mastered Wind and Fire nature transformations, that should be enough for now."

Once one understood the principle of the Rasengan, it was easy to learn, but taking the next step and throwing the sphere was extremely difficult.

The next day, he was still at the Training Ground.

Uchiha Gen lowered his head and looked at his palm. Two clones beside him continuously fed Chakra into it.

Although this method looked clumsy, the facts proved that Naruto's approach was quite effective in the early stages.

The time required had gone from over ten seconds to three seconds. The Rasengan was now more or less ready for actual combat.

Uchiha Gen activated his Sharingan, two black tomoe circling within his pupils.

He could see the Chakra flow within the Rasengan with perfect clarity.

"Dynamic vision, copying, perception... no wonder the Sharingan is so formidable."

He felt that the Rasengan was especially suited for the Uchiha to learn. By that logic, the Flying Thunder God might be as well.

"Thinking about running before I've even learned to walk."

Uchiha Gen shook his head with a laugh and dispersed the Rasengan's Chakra. For now, he needed to honestly master his existing ninjutsu and turn them into actual combat power.

Although this body possessed combat experience, how much of it he could still use remained unknown.

In other words, he would have to go to the battlefield eventually, and going to the battlefield meant killing people.

"Killing people... it felt so distant, yet it happened here every day."

Uchiha Gen was not a coward. He simply tried his best to avoid putting himself in danger.

When faced with a life-or-death crisis, people had many different reactions. Some froze in terror, while others became so frightened that their entire bodies went weak.

But Uchiha Gen was the type whose adrenaline would surge, sending him straight into a blood frenzy.

He remembered encountering a half-grown dog on his way home from school as a child. The dog was usually chained up at a neighbor's house, but somehow, it had gotten loose that day.

Uchiha Gen had only been in elementary school then. Carrying his backpack, he had only wanted to get home quickly, but the dog started barking loudly behind him.

The moment he ran, the dog barked even more fiercely. When he looked back and saw it baring its fangs, he was terrified out of his wits, his mind going completely blank.

He immediately turned around, grabbed his backpack, and smashed it at the dog. The bag was full of stationery and books, and the blow landed solidly. The dog yelped miserably and tucked its tail as it tried to retreat.

But Uchiha Gen had already entered a blood frenzy. He charged after it without caring about anything, beating and smashing at it all the way. Books and pens scattered across the ground as he chased the dog through half the village.

Only when adults discovered them and stopped him did he gradually calm down. Feeling wronged, he cried for a long while.

Dog:??

"The Rasengan is settled for now. Next is the Three-Body Technique. The Body Flicker Technique in particular is worth digging into."

The technique was simple, but that did not mean it was weak. Uchiha Gen remembered that Body Flicker Shisui had become famous precisely through this technique.

According to the principle recorded in the scroll, one covered the soles of one's feet in Chakra before rapidly moving toward a visible destination. Since the speed was so great that it looked like teleportation, it was also called the Body Flicker Technique.

Uchiha Gen practiced it and discovered that after covering the soles of his feet with Chakra, his body became light as a swallow. He could also cling to walls and tree trunks.

"It's useful, all right, but how did Shisui connect this Body Flicker Technique with the Clone Technique?"

The anime's simple explanation was that Shisui Uchiha's clones had physical bodies, with each clone seeming just like the real person. It sounded like the Shadow Clone Technique.

"But the Shadow Clone Technique requires far too much Chakra. It probably wasn't that."

He looked up at the sky. Another day was about to end, so he simply finished training and went out to find something to eat.

That was right. Ever since most of the clansmen had gone off to fight, no one had been responsible for his three daily meals.

Fortunately, he was not some helpless baby who could only wait for others to bring him food, so he went out to forage for himself.

"It's nice without pollution. The mountains are clear, and the waters are beautiful."

After looking around, he decided not to enter the forest at night for fear of an accident. Instead, he went to the waterfall where Madara had once brought the brothers to train and caught fish.
