"This is the Yin Seal and the Hundred Healings Technique. I didn't expect Tsunade-sama of this era to master this jutsu too. I'd only heard of it before, but now I finally get to witness its power firsthand."
"To think such severe injuries could heal in an instant—truly incredible!"
At some point, Imperial Lee had positioned himself not far ahead, grinning widely while giving a thumbs-up.
"Martial arts are indeed impressive! But ninjutsu won't lose to them either! Kid, the fight's just getting started!"
Tsunade shouted, charging once more at Imperial Lee.
"I feel it! Tsunade-sama's burning spirit! Yes! The fight's only just begun!"
Lee leaped forward as well.
*BOOM!*
*BAM!* *BAM!* *BAM!* *BAM!*
Another clash of straightforward, brutal punches.
As the shockwaves spread, Kakashi, Shikaku, Naruto, and the others hurriedly dodged.
They widened their eyes, watching the figures now locked in a fierce battle.
With the Yin Seal and Hundred Healings Technique activated, Tsunade's regeneration surged, but her strength, speed, and intuition sharpened dramatically, keeping her body at peak condition.
This allowed her to trade blows with Imperial Lee.
*BAM!* *BAM!* *BAM!* *BAM!*
Thunderous roars erupted continuously between them.
Imperial Lee's figure was occasionally thrown back, but he'd quickly rise and charge at Tsunade, knocking her back.
In turn, Tsunade would retaliate with equal ferocity.
Their fight was savage, with no defense whatsoever.
Over time, thanks to the Yin Seal, Imperial Lee began showing severe injuries—his body tattered, bleeding heavily in many places.
*BOOM!*
Another clash, just as Imperial Lee was flung back.
Imperial Neji frowned and shouted:
"Spirit and youth are important, but… stop playing around. You've enjoyed the fight enough, haven't you?"
"Huff… huff… What do you mean by that? Are you saying Lee hasn't used his full strength yet, Neji?"
Tsunade, panting from Neji's shout, asked brusquely.
Kakashi and Shikaku were stunned.
This otherworldly Lee, nearly matching Tsunade—one of the Legendary Sannin—hadn't even shown his full power?
That was outrageous!
"Why don't you ask Lee himself? Wouldn't you find out?"
Imperial Neji's expression was cold.
Tsunade turned her gaze to Imperial Lee, who stood up, casually brushing off dust.
"Ah! Sorry! Sorry! Since I just arrived in this world and immediately faced an opponent like Tsunade-sama, whose strength-based fighting style is my favorite, I got carried away enjoying it!"
Imperial Lee scratched his head with his right hand, looking embarrassed.
"You stinking brat! I'm giving you one last chance! Show your full power now! Or don't blame me for being harsh!"
Tsunade, hearing his answer, had eyes practically spitting fire.
She'd been utterly underestimated!
"This time, for sure! Eight Gates! Gate of Opening, Gate of Healing, Gate of Life, Gate of Pain, Gate of Limit, Gate of View, Gate of Wonder, Open!"
Imperial Lee raised both arms high, shouting loudly.
The next moment, a surge of chakra and Qi erupted, soaring into the sky!
A terrifying airflow raged, whipping up fierce winds within a hundred-meter radius.
Even the clouds above Imperial Lee were churned into chaos by this terrifying power.
"The Eight Gates… he actually mastered this too… Could they really be from another world? Is everything they said true?"
Kakashi muttered, his visible left eye showing unbearable seriousness.
"Damn… The Eight Gates Formation, Konoha's Forbidden Technique. It's said that opening all eight gates grants power far beyond a Hokage…"
"Lee's opened seven gates now. Though not all eight, combined with his base strength, Tsunade-sama might no longer be his match." Shikaku said, worried.
"Awesome! A perfect blend of ninjutsu and martial arts! Incredible, Lee!" Naruto's eyes sparkled.
"…"
Tsunade fell silent, cold sweat trickling down her forehead.
"It's not over! Demon Spine! Open!"
Imperial Lee shouted again.
Everyone watched in shock as the muscles on his back writhed and twisted, forming a terrifying demonic face.
The demon's face grinned menacingly, its mere sight sending chills down spines.
"Hey, that's too much! Are you trying to kill Hokage-sama?"
Imperial Neji raised an eyebrow and shouted.
"Relax, I know my limits, Neji! Watch closely, Tsunade-sama! This is my true full power!"
Imperial Lee shouted, his voice fading.
Tsunade focused entirely, staring sharply at Lee, not missing a single movement, ready to defend.
But no one expected that as his voice faded, she could do nothing.
Her vision blurred, and Imperial Lee's towering, oppressive figure appeared before her! His massive shadow engulfed her! A fist the size of a human head slammed down!
At that moment, Tsunade felt unprecedented pressure and the aura of death!
If it hit, she'd die! She'd definitely die! Even the Yin Seal couldn't save her!
'I… will die? Die in a sparring match with some unknown person claiming to be Lee from another world?'
'Die under his fist?'
In that instant, countless images flashed through Tsunade's mind.
She recalled her childhood with Jiraiya and Orochimaru.
Her failed love with Dan.
Her struggles as Hokage.
The fist loomed larger in her vision! Until… it grazed past her right ear!
*BOOOOOOM!*
A deafening roar, accompanied by a storm, pierced her eardrums, leaving Tsunade momentarily dizzy.
But thanks to the Yin Seal, she quickly recovered.
When she came to, she saw Imperial Lee's towering figure and… his signature toothy grin.
Along with the worried faces of Kakashi, Shikaku, Naruto, and Sakura.
"Tsunade-sama! Are you okay?"
"Grandma Tsunade! How are you?"
"I… I'm fine…"
Tsunade answered dazedly, turning to look behind her, her pupils shrinking.
What did she see?
The dense forest was mostly gone, replaced by a barren clearing at least a hundred meters wide and three or four kilometers long!
"This… was from that punch?"
Tsunade took a deep breath and asked.
"Yes, this is Lee's full-power attack." Imperial Neji said coldly.
Tsunade's eyes flicked to Kakashi and Shikaku.
Both nodded slowly.
Shikaku said bitterly, "This is indeed the result of Lee's single punch… truly destructive power like a natural disaster."
"So… I've been fighting a monster like this all along?" Tsunade gave a bitter smile.
Her face showed unspeakable bitterness and disappointment.
The gap was too vast!
