Sign-in! Might Guy!

"I've only gotten weaker, that doesn't mean you've gotten stronger."

The moment Uchiha Rei stepped out of the small hut, he noticed two figures hidden in the shadows tailing him. They were Konohagakure's Anbu, the Third Hokage's spies.

Uchiha Rei's gaze was calm, unconcerned. Last night, he had quietly used "Phantom Seal" to temporarily suppress the poison, locking down the abnormal fluctuations in his Chakra.

This way, even the Hyuga Clan's Byakugan, or the Aburame Clan's sensing insects, wouldn't be able to detect his true condition.

Rei had indeed "gotten weaker," but he knew it was merely an illusion. From today onward, the news of his weakened state would reach certain ears.

The morning sun shone upon Konohagakure's public training grounds, where Might Guy had already completed his victory reward.

One hundred sets of handstand push-ups. Sweat dripped from his temples, yet a confident smile played on his lips.

Rei's internal poison had now been alleviated, so the requirements for his sign-in location weren't as strict.

Since he had come to the public training grounds today, Many ninjas in Konohagakure had formed bonds at the public training grounds.

Since he was here, he might as well.

He might as well sign in here.

The familiar system prompt sounded in his ears:

[Ding!]

[Sign-in Location: Konohagakure Public Training Grounds!]

[Sign-in Successful!]

[Reward Obtained: Konoha Style Taijutsu - Konoha Whirlwind!]

[Hint: This sign-in point can be signed in repeatedly!!]

A clear sense of power quickly spread through his entire body, especially stimulating the vitality of his leg muscles. He subconsciously swung a leg, the wind whistling, powerful enough to split the air.

"Konoha Whirlwind... it's actually one of Might Guy's signature taijutsu," Uchiha Rei frowned slightly, then looked at the green figure not far away with a half-smile. "Could it be that there really is some so-called 'bond' between him and me?"

Although this power wasn't top-tier, the feeling of his cells being stimulated was incredibly real. This meant his Chakra recovery speed was accelerating, and though slight, his combat power was gradually recovering.

He had already made up his mind; he had to come back and sign in again tomorrow.

"Uchiha Rei-kun!" Might Guy embraced him, his voice booming as if exploding from his chest, "Today is the happiest day of my life! To think someone is willing to train taijutsu with me!"

"Might Guy, I'm also very happy with today's training," Uchiha Rei was caught off guard by the sudden embrace, but he didn't refuse, merely patting the other's shoulder gently. "Are you free tomorrow? I want to train taijutsu with you again."

The communication between men never required beating around the bush.

"Are you serious?" Might Guy's eyes shone like twin suns, his entire being radiating light. His thick eyebrows, like burning flames, intensified instantly.

"Of course, I keep my word," Uchiha Rei smiled.

"From today on, you're my new partner!" Might Guy was so excited he almost exploded on the spot, gripping Uchiha Rei's hand tightly as if he had grasped life's most precious bond.

"Then let's set a time," Uchiha Rei withdrew his hand, his expression serious.

"How about five in the morning tomorrow?" Might Guy asked.

"No!" Rei shook his head sternly. The sign-in time was too late. "Too late! I think midnight is the only time worthy of youthful passion!"

Might Guy was stunned and gave him a thumbs-up.

"Alright! See you then!" Might Guy responded, almost shouting, "Let's spill the sweat of youth together!"

Watching the other party earnestly utter these passionate lines, Uchiha Rei couldn't help but sigh inwardly: he had indeed underestimated the "bonds" and "will" of this world.

The man who had almost failed the Ninja Academy graduation exam and only managed to get by through sheer taijutsu was now Kakashi Hatake's "arch-rival" in Konoha.

Little did Rei know, Asuma Sarutobi, who had loved flirting since childhood, considered Uchiha Rei his lifelong rival.

Although Uchiha Rei had always been low-key in the Ninja Academy, rarely showing off, only revealing his talent in genjutsu and ninjutsu when necessary, his overwhelmingly handsome face always attracted the attention of girls. Whenever he passed by, it would cause a small commotion. For Asuma, who was skilled at flirting but always met with cold shoulders, this was an utter humiliation.

In young Asuma's heart, he should have been the one who couldn't maintain his cool for more than three seconds, not Uchiha Rei, who could make girls flock around him without saying a word. He had challenged Uchiha Rei publicly many times, from ninja tool duels to taijutsu competitions, and even ninjutsu clashes, but the results were always one-sided.

Ten losses in ten battles.

Especially in genjutsu.

With the Uchiha clan's bloodline talent, Uchiha Rei had outmatched Asuma with genjutsu in six direct confrontations, leaving him trapped in embarrassing dreams or disoriented illusions, defeated miserably. Each time he woke up, Asuma would be so angry he'd beat his chest and stamp his feet, secretly vowing revenge.

Although Uchiha Rei appeared outwardly calm, he had long ago dismissed Asuma's "kindergarten-level" provocations as uninteresting daily occurrences.

His true target had always been the genius Uchiha Itachi.

"If you can't even beat Uchiha Itachi, what kind of rival are you, Asuma?" Uchiha Rei often thought to himself.

These defeats dealt a huge blow to Asuma. From then on, he gradually stopped flirting in school.

It wasn't that he didn't want to, but no one paid him any attention anymore.

In his heart, even the most beautiful female ninja lost her luster under Uchiha Rei's radiance.

Asuma's focus gradually shifted. He no longer obsessed over flirting but was determined to defeat Uchiha Rei.

He began to diligently study Genjutsu Resistance Techniques.

Kurenai Yuhi, a female genjutsu ninja of the same year, had interacted with Uchiha Rei many times regarding genjutsu, which also caused Asuma's displeasure.

"I already arranged a match, and you, woman, insisted on dragging Uchiha Rei off to practice Genjutsu!" Asuma Sarutobi gritted his teeth. He harbored resentment in his heart towards Kurenai Yuhi's "interference"—believing she had repeatedly obstructed his friendly duels with Uchiha Rei.

Meanwhile, on the other side, Might Guy, after parting ways with Uchiha Rei, excitedly broadcasted a major event to the entire village:

"Kakashi! I've found a new youth partner!"

Kakashi lazily flipped through his book, not even lifting his head. "Then you won't be looking for me anymore?"

"Nonsense!" Guy waved his arms forcefully. "You are my lifelong rival! Uchiha Rei is my lifelong best friend! Youth should have enemies, and it should have partners; this is complete youth!"

Next, Might Guy excitedly relayed this message to a second person, then a third, until it reached Asuma Sarutobi's ears.

"What!? Uchiha Rei became your friend?" Asuma almost exploded. "Why did it turn out like this? It was me first, it was clearly me first...!"

"Don't you know?" Asuma said with a serious expression. "Uchiha Rei was poisoned and is very weak. He's still insisting on training Taijutsu with Guy. Aren't you harming him by practicing with him?"

"Poisoned... poisoned?" Might Guy was greatly shocked, his expression immediately changed, and his fists clenched tightly. "Uchiha Rei-kun, to persist in training while injured, truly... he is the true teammate of my life!"

Might Guy's eyes welled up with tears, and he slapped Asuma's shoulder. "You finally understand what youth is!"

"I'm going to find Lady Tsunade right now to detoxify Uchiha Rei!" Before Might Guy even finished speaking, he had already vanished like a green lightning bolt at the end of the Konohagakure streets.

Asuma opened his mouth, but before he could say anything, only a youthful afterimage remained, burning in the sunlight.
