From the night of genocide, marching towards the strongest.

Sasuke leans more towards the second option, since Obito Uchiha is only exceptionally talented in the Sharingan, and is otherwise utterly incompetent.

Most of his strength lay in the seemingly unbeatable Kamui, but once he lost Kamui and the intelligence advantage, Obito Uchiha was really just that.

In the original timeline, during his battle with Kakashi in the Kamui dimension, despite having a White Zetsu body and a Rinnegan, he was still defeated by Kakashi.

"As the saying goes, shame is the mother of courage. Come on, let me see how much progress you've made lately?"

Sasuke chuckled and beckoned to Obito Uchiha with his finger, speaking in an extremely contemptuous tone.

Although his expression was disdainful, he was actually keeping a close eye on his surroundings.

After all, the other members of the Akatsuki organization had not yet appeared, so he could not afford to be too careless.

"Humph!"

Obito Uchiha's eyes turned cold: "You fool who doesn't know what's good for him!"

As soon as he finished speaking, Obito Uchiha clapped his hands together.

Wood Release? The Birth of the Tree World!

Bang bang bang!

The moment Obito Uchiha finished releasing his ninjutsu, many trees suddenly sprang up from the ground, as if uprooted. The once empty ground instantly turned into a forest, and it was expanding towards Sasuke at an extremely exaggerated speed!

As the tree trunks and branches spread through the forest, they seemed to transform into twisted, venomous snake tentacles, sweeping across Sasuke's direction.

Faced with the overwhelming Wood Release technique, Sasuke's crimson Sharingan remained deep and calm, but the next moment, his eyes seemed to burst forth with lightning.

With a thunderous clang, Sasuke transformed into a fierce, unpredictable bolt of lightning, flashing through the dense, intricate forest like a net, and charging towards Obito Uchiha.

"Humph!"

Obito Uchiha snorted coldly, showing no sign of panic or attempt to dodge. The Death Scythe appeared in his hand, its blade gleaming with sharpness, and he charged straight at Sasuke.

boom!

The two figures collided at the same time, and in an instant, streaks of lightning and countless sharp air currents scattered in all directions, dust rose, and a huge air wave was created.

Click, click!

The sound of swords clashing violently rang out. After a fierce exchange, the two continued their battle. The Grim Reaper's Scythe and the Futsu-no-Mitama Sword clashed, locked in a fierce confrontation, neither giving an inch.

"what?"

Sasuke was surprised to see that Obito Uchiha had actually withstood his attack head-on, but he quickly recovered.

Sasuke is not known for his strength, although his strength increases greatly after entering the "Enlightenment" state, making him one of the best in the ninja world in terms of wrestling.

However, in terms of pure strength, he is still not the number one in the ninja world. Three months ago in the Land of Swamp, Kisame Hoshigaki was able to fight him head-on without being at a disadvantage.

Three months later, Sasuke's power is stronger than before, but there has been no qualitative change.

Tobi, the combat-type White Zetsu, is extremely special. He once possessed Obito's body when Obito was still a teenager and his body had not yet fully recovered.

Obito's power increased instantly, allowing him to do what Tsunade's Super Strength Fist could do.

Obito's current strength is far greater than his weakened self at that time. With Tobi's possession, in terms of pure power, he is no less than Tsunade, the strongest ninja in the current ninja world.

Even though Sasuke's power is now stronger than it was three months ago, he still can't suppress a "Tsunade" in a direct confrontation.

"So your power after turning into a monster isn't all that great, Uchiha Sasuke!"

Looking at Uchiha Sasuke with his back covered in bone spikes and black wings, looking like a monster, Uchiha Obito's eyes flashed with mockery as he provoked him.

Despite the immense power emanating from Sasuke's sword, Obito firmly gripped the Grim Reaper's scythe, showing no signs of weakness.

Even though the wind style counters the lightning style, the sharp energy on Obito's scythe still remained, while the lightning wrapped around Sasuke's Futsu-no-Mitama sword had dissipated considerably, no longer in its highly concentrated and unified state.

From this perspective, it seems that Obito Uchiha had a slight advantage in this head-on confrontation.

"Is that all? Your current power is beyond your imagination, Uchiha Sasuke!"

Obito Uchiha gave a cold laugh, and a tremendous force surged from his body once again, causing the swords that had been locked in a stalemate to press down on Sasuke.

When possessed by Tobi, he was extremely confident in his own power, believing that no one in the current ninja world could rival him in a physical contest.

Even Tsunade, known for her superhuman strength and physical prowess, and the Fourth Raikage couldn't do it!

Of course, Obito Uchiha also knew that the outcome of a battle between ninjas was not simply a matter of who was stronger.

But that doesn't stop him from getting back at Uchiha Sasuke first!

Moreover, given that Wind Release counters Lightning Release, Sasuke Uchiha might suffer a great loss!

However, faced with Obito Uchiha's provocation and the ever-increasing power emanating from the Death Scythe, he...

Sasuke glanced at the Grim Reaper's scythe with interest, then grinned at Obito's cold gaze.

The next moment, a thunderous sound rang out from Sasuke's body, and countless crackling electric snakes surged out from his various acupoints in a strange pattern, spreading and wandering everywhere, and suddenly gathered together to form a lightning armor with Sasuke at its core, with lightning flashing and intertwining and dazzling electric light!

Lightning Release Chakra Mode!

"This is!?"

The blinding light that suddenly burst from Sasuke's body made Obito Uchiha instinctively close his eyes slightly and tilt his head to the side.

Obito unconsciously closed his eyes in the bright light, but immediately realized what was happening and was about to do something.

The next moment, an immense force, as powerful as a mountain, surged forth like a turbulent sea, instantly reversing the situation where he had been suppressing Uchiha Sasuke in the struggle.

In terms of pure power, Sasuke in his "Enlightenment" state was indeed inferior to Obito Uchiha, who was empowered by Tobi's possession.

But once Sasuke entered Lightning Release Chakra Mode, the situation changed completely.

Lightning Release Taijutsu is already the best body-strengthening technique in the entire ninja world. Entering Lightning Release Chakra Mode, by concentrating Lightning Release Chakra throughout the body, can activate the physical body, greatly increasing strength, speed, and defense.

Furthermore, even within the Lightning Release chakra mode, there are differences. For instance, the Fourth Raikage's Lightning Release chakra mode prioritizes speed, achieving astonishing speed comparable to Minato Namikaze. In the original timeline, he could instantly dodge Sasuke Uchiha's Amaterasu, his speed resembling blue lightning.

The Third Raikage, who taught Sasuke, focused on strength and defense!

In terms of strength, he could fight the fully-formed Eight-Tails head-on in hand-to-hand combat with his human body, and in terms of defense, he could withstand Naruto's Wind Release: Rasenshuriken without taking any damage.

Having learned the Third Raikage's Lightning Release Chakra Mode, Sasuke naturally experienced the most significant boosts in strength and defense after entering Lightning Release Chakra Mode!

Bang!

A loud blast of air echoed through the ground, sending Obito Uchiha flying backward. He quickly used his scythe to pin himself to the ground and regain his footing.

He's using ninjutsu from the Raikage lineage!?

As soon as he regained his footing, Obito Uchiha saw that his vision was filled with endless flashes of lightning, accompanied by an indestructible and massive aura that surged toward him like a landslide and a tsunami!

Righteous Thunder Sinks, Wrathful Thunder Axe!

Sasuke, who usually uses the Futsu-no-Mitama Sword to stab, now surprisingly used a slash!

Upon seeing this, Obito Uchiha's eyes widened in shock, and he instinctively wanted to use Kamui to dodge. However, for some reason, after gritting his teeth, Obito did not choose to use Kamui. Instead, he took out his Flame Fan and held it in front of him.

Boom!

A tremendous explosion resounded, and the ground suddenly sank more than ten meters deep. A huge shockwave composed of dust, gravel, blade light, wind blades, and lightning shot into the sky!

At the center of the collision, Obito Uchiha was bent over, holding his Flame Fan tightly against the longsword wrapped in endless lightning. However, his arms were now cracked and his bones were making a series of sounds as if they could not bear the weight.

Strangely, the lightning on the Futsu-no-Mitama Sword was absorbed by the Flame Fan, causing it to dissipate and dim considerably.

"That's it?"

Sasuke, holding the Futsu-no-Mitama sword, looked down at Obito Uchiha, seemingly unaware of the sword's unusual appearance. A slight smirk appeared on his lips as he spoke mockingly.

"I thought you were more courageous? Is this all?"

Sensing that Obito was trying to stand up, Sasuke tightened his grip on the longsword, pressing Obito's body, which was about to straighten up, back down.

"hehe...."

"Foolish fellow, you have no idea what power the Flame Fan represents!"

Faced with Sasuke's mockery and the ever-increasing power, Obito Uchiha did not fly into a rage and lose his mind. Instead, he let out a cold laugh and said, word by word:

"Uchiha Rebound!"

In an instant, a strange change occurred. The lightning on Sasuke's sword suddenly dissipated, seemingly absorbed entirely by the Flame Fan.

The Flame Fan suddenly burst forth with a dazzling white light, and a tremendous power was accumulating and brewing within it, ready to be released!

At this moment, Obito Uchiha was already eager to see Sasuke's incredibly horrified expression. He could even picture Sasuke suffering a great loss when he was caught off guard!

However, to Obito's surprise, Sasuke showed no sign of panic. Instead, he wore a wicked smile and looked at him with a strong sense of mockery.

Sasuke held a sword in his right hand, while his left hand formed a tiger seal!

The mark of the tiger!?

Upon seeing this, Obito Uchiha's cold gaze faltered, a chill creeping into his heart. His expression changed drastically in an instant, and at the same time, the ground behind him suddenly began to churn, as if something was about to emerge.

In an instant, Obito Uchiha's buttocks twitched involuntarily, and an indescribable chill spread throughout his body.

Damn!

Without any time to think, Obito Uchiha almost instinctively and hastily activated Kamui Intangibility.

It forcibly stopped the energy of the Flame Fan, which had been building to its limit, like a volcano about to erupt.

"Well."

After entering the intangible state, Obito Uchiha let out a painful groan, and a trickle of blood flowed from the corner of his mouth.

The Uchiha counterattack was forcibly stopped. Under the immense energy, even though he was currently possessed by Tobi, he still suffered considerable internal injuries.

"Hehe, it seems you still have a deep memory of what happened last time."

Sasuke looked at Obito Uchiha, whose eyes were as cold and icy as ice, and said mockingly.

Sasuke knew what Obito was going to do the moment he took out his Flame Fan to meet his attack head-on.

The Flame Fan is a family symbol passed down through generations of Uchiha clan leaders. Part of its material is carved from the branches of the Divine Tree, and it also possesses the same property as the Divine Tree: absorbing chakra.

By absorbing the enemy's attack chakra, the chakra is transformed into the nature of wind, and then reflected back as a storm. This is the essence of the Uchiha Reflection.

This technique is powerful and unexpected; many people have died as a result of it.

However, even though the Flame Fan can deflect enemy attacks, the user also has to bear most of the attacker's force.

So Obito Uchiha was almost forced to his knees by Sasuke's sword, while Madara Uchiha in the original timeline was not moved at all by Naruto's small Rasengan Tailed Beast Ball in Kurama Mode. Instead, he instantly knocked Naruto back to his original form from Kurama Mode.

At the same time, the flame fan also needs to go through three processes: absorption, transformation, and release.
