Uchiha Seisei knew that Shisui was very strong in Taijutsu and had mastered a secret technique that complemented Taijutsu well.
Even if they both attacked together, they might not gain any advantage.
It would be better to use long-range Ninjutsu to deplete Shisui's Chakra.
"Fire Release: Mighty Dragon Fire Jutsu!"
The two of them formed hand seals simultaneously and unleashed Fire Release with all their might.
Whoosh!
Shisui ignored the fire dragon that was about to charge out and rapidly approached Uchiha Seisei.
The distance between them and Uchiha Seisei's fire dragon grew closer and closer to Shisui.
When the fire dragon was merely a decimeter away from Shisui, he made his move.
The immense amount of Chakra he had prepared earlier erupted, and Shisui's Breath of Flame was pushed to its limit.
"Green Flame!"
Shisui opened his mouth and spewed forth a green flame as thick as an arm.
Compared to the two incoming mighty fire dragons, the flame Shisui expelled appeared very weak.
Because Uchiha Seisei's fire dragon was three times larger than Shisui himself, the flame Shisui released seemed insignificant in front of the massive fire dragon.
Whoosh!
The green flame connected with the orange-yellow flame.
In the next instant, the fire dragon was engulfed by the green flame and vanished in front of Shisui, as if it had never existed.
Uchiha Seisei was stunned, almost thinking this was another Genjutsu.
However, his body honestly told him that his Chakra was very stable, and he wasn't under a Genjutsu.
Due to the close proximity, the failure of their Ninjutsu clash, and Shisui's overwhelming Fire Release, when they tried to dodge, the green flame was already burning before their eyes.
At this moment, Uchiha Seisei's life flashed before his eyes, from being born to entering the Ninja Academy, graduating to become a ninja, and becoming an Uchiha Elder—all his memories flashed rapidly through his mind.
Thankfully, the green flame disappeared seven centimeters away from them, under Shisui's control.
Uchiha Seisei took two steps back, nearly collapsing to the ground, gasping heavily, with sweat beading on his forehead and his shirt soaked through with perspiration.
The other Uchiha ninja wasn't any better off, also looking as if he'd just escaped death.
Shisui also let out a heavy breath.
Even though he had been frantically cultivating Green Flame all week, Shisui's mastery level was still low, far from truly learning it.
Shisui found it difficult to use various Green Flame versions of Fire Release like Mokgetsu could, not even able to compress it for use.
Only in Breath of Flame Chakra Mode could he drain most of his body's Chakra to barely produce some high-temperature green flames.
Therefore, Shisui had been striving to close the distance, because without doing so, the length at which he could exert Green Flame wouldn't reach anyone.
However, the Green Flame hadn't disappointed Shisui. Even though he hadn't fully mastered it, its power was still formidable, the strongest Fire Release he knew, creating a significant gap with other Fire Releases.
"What, what Fire Release is that?" Uchiha Seisei stopped, still in shock, and asked.
Shisui did not answer Uchiha Seisei's question; the Green Flame was a Ninjutsu taught by Mokgetsu, which he couldn't casually disclose.
"You might really be able to lead the Uchiha back to glory," Uchiha Seisei didn't continue asking and deactivated his Sharingan with a sigh.
In Shisui, Uchiha Seisei saw the shadow of Uchiha Madara.
It had nothing to do with personality, just the unparalleled strength of Uchiha Madara.
Uchiha Seisei felt that if Shisui continued, he might be able to cultivate to the same realm as Uchiha Madara.
"I'll do my best," Shisui replied.
He didn't dare say he would definitely lead the Uchiha to glory, but he would do his utmost to make the Uchiha better, at least not like they were now.
"That's good enough." Uchiha Seisei smiled faintly, turned, sighed, and walked toward Nankai Shrine.
There were still Uchiha ninja who hadn't been defeated, but for him, it was actually already a loss.
