Heaven-Defying Talent, Second Grandfather's Prejudice

As he retreated from the fireballs, Uchiha Dan, whose feet hadn't yet touched the ground, rapidly condensed Chakra into his right fist and threw a powerful punch.

Monster Strength Technique!

The instant his fist met the rock, the hard stone exploded. Uchiha Dan used the recoil to continue his retreat.

But almost simultaneously, Tsunade, who had followed closely behind the rocks, arrived before Uchiha Dan. She landed a devastating kick, the "Heavenly Foot," on his chest before he could even react.

Bang!

Uchiha Dan's body instantly dissolved into a puff of smoke.

Shadow Clone!

At the same time, a water pillar as thick as a wrist shot out from ten meters to his side, aimed at Tsunade.

Tsunade seemed to have anticipated this. The moment she landed, the Chakra in her toes, using the precise control of her Super Precision Mode, firmly adhered to the ground.

Using the immense suction, Tsunade's body sank sharply, allowing her to narrowly dodge the water pillar.

While dodging the water pillar, Tsunade leaped to the side, narrowly avoiding another water pillar that sliced down from above like a sharp sword.

The hard rock ground was instantly cut in half the moment it touched the water pillar, but the water pillar didn't stop. Instead, it swept horizontally towards Tsunade.

Water Style: Water Severing Wave.

This was a Water Style Ninjutsu developed by Tobirama Senju. It involved rapidly spitting out a high-pressure, straight water jet from the mouth, which continuously cut targets like a sharp blade.

However, this sweep still failed. Tsunade dodged the water pillar by bending down again and charged towards Uchiha Dan once more.

At this moment, the water pillar stopped spraying.

"Let's see how you dodge this time!"

With a soft cry, Tsunade appeared above Uchiha Dan as if teleporting and brought down a heavy kick on him.

Having sparred for so long, Tsunade knew Uchiha Dan's situation very well.

For some lower-level Ninjutsu, like Fire Style: Great Fireball Technique, Uchiha Dan could use a Shadow Clone to perform it.

But for Ninjutsu of the Water Style: Water Severing Wave's level, Uchiha Dan currently had to recall his Shadow Clone before his main body could use it.

Not everyone was Uzumaki Naruto, possessing bottomless Chakra, who could use high-level Ninjutsu like Wind Style: Rasenshuriken, which consumed a massive amount of Chakra, with Shadow Clones without restraint.

Nor was everyone like Edo Tensei Madara, whose Shadow Clone could unleash the Complete Body Susanoo.

Uchiha Dan's talent was astonishing, but his current Chakra reserves were only at the level of an average Kage. He couldn't squander it like a Jinchuriki.

In a panic, unable to cast Ninjutsu again, Uchiha Dan could only condense Chakra throughout his body and raise his left arm to block.

Boom!

As the immense force collided, the hard ground centered on Uchiha Dan's feet instantly cracked outwards for dozens of meters.

Under the massive impact, Uchiha Dan spun several times in the air, holding his body to reduce the shock, and then used the momentum to deliver a similar kick towards Tsunade, who had just landed.

However, Tsunade was prepared for this. She threw out a punch, which met the descending leg squarely.

This clash stirred up a violent gust of wind, which directly blew away the already shattered ground, making the entire surface sink.

Originally, Uchiha Dan intended to use the recoil to create distance from Tsunade, but the moment he moved, Tsunade appeared before him like a phantom and launched a storm of attacks at him.

Thus, the two began to fight with pure Taijutsu, their figures constantly shifting as they chased and attacked each other with punches and kicks, fighting fiercely.

Uchiha Dan had only recently mastered Monster Strength Technique, strictly speaking, less than ten days ago, and he hadn't mastered Super Precision Mode yet.

Coupled with his lack of combat experience, he was no match for Tsunade in Taijutsu. But at this point, he had no other choice.

Tsunade gave him no chance to disengage, forcing him to fight with Taijutsu and leaving him no opportunity to use Ninjutsu.

Under the rapid and fierce exchange, Uchiha Dan gradually fell into a disadvantage after a short while.

Fortunately, he had been practicing the Chakra Body Strengthening Technique since six years ago, giving him a powerful physique and astonishing reaction speed, which allowed him to barely contend with Tsunade.

However, the gap still existed when relying solely on Taijutsu.

Ten minutes later, Uchiha Dan lay on the ground, gasping for breath, ending his daily sparring session once again as the loser.

Before his transmigration, Uchiha Dan had underestimated Tsunade's strength.

After all, not every Taijutsu ninja was Might Guy, who would open the Eight Gates at the slightest disagreement.

But after actually fighting Tsunade, Uchiha Dan realized he was wrong, profoundly wrong.

Because of him, Tsunade had never slacked off in her training over the years.

The laziest of the Sannin was now the most diligent.

She had even quit gambling, dedicating all her time to training and researching Medical Ninjutsu.

This made Tsunade, who was already exceptionally talented, much stronger than Orochimaru and Jiraiya at this period, reaching a solid Kage level.

Most importantly, Tsunade was still improving, her potential terrifyingly high, as if blessed by heaven.

In the original timeline, Tsunade, who was so lax in her training and had neglected it for over twenty years, could still unleash a strong Kage-level combat power in the Fourth Great Ninja War.

It's impossible to imagine how far she, who has never slacked off, will go in the future.

However, while Uchiha Dan was shocked by Tsunade's strength, Tsunade was truly stunned.

This was because Uchiha Dan's progress speed left her dumbfounded, and she couldn't help but call Uchiha Dan a complete monster.

Just a month ago, Uchiha Dan was completely green, utterly ignorant of ninjutsu and combat.

But now, Uchiha Dan could fight her to a standstill even when Tsunade went all out.

This was without Uchiha Dan using Sage Mode or the Sharingan.

Once Uchiha Dan used Sage Mode, Tsunade was no longer his opponent.

If another month passed, wouldn't he be able to crush her under normal circumstances?

It wasn't that Uchiha Dan's talent was truly that much greater than Tsunade's.

For the past seven years, although Uchiha Dan hadn't trained, his thoughts on ninjutsu and combat had never stopped, and he had simulated countless battles in his mind.

But in the past, Uchiha Dan was merely a theorist who had never properly performed any ninjutsu or fought in a real battle.

So, even though he possessed astonishing talent, he still needed time to adapt when it came to practical application.

Fortunately, with Tsunade as a patient and meticulous super sparring partner, he was able to integrate all his concepts into combat in just one month.

To put it simply, Uchiha Dan had only been training for one month.

Being able to fight Tsunade, who had already reached Kage-level strength and was going all out, for twenty minutes before losing, without using Sage Mode or the Sharingan, was already a remarkable miracle.

Uchiha Dan's incredible rate of progress suddenly made Tsunade understand why her grand-uncle guarded against him.

Was it because he saw that Uchiha Dan possessed unparalleled talent and wanted to nip him in the bud?

As for the reason.

Because he was Uchiha.

Everything made sense now!

But Tsunade became even angrier.

Just because he was Uchiha, he couldn't fulfill his potential? His life would be ruined? He would be eliminated?

In the end, it was the prejudice in her grand-uncle's heart that was at play.

Weren't Uchiha ninja also Konoha ninja?

From her understanding of Tobirama Senju, Tsunade had reason to believe that if Uchiha Dan wasn't part of the Uchiha Clan, her grand-uncle might have fully trained him, adding a super-strong ninja to Konoha.

To think that he would go to such lengths simply because of the name Uchiha was truly laughable.
