The two-tomoe Sharingan spun rapidly, searching for an opening in Minato. It had to be a one-hit kill, or the opportunity would be lost.
Minato had the same thought. He was constantly looking for an opportunity to carve the Flying Thunder God formula on Uchiha Hai, and then, with a surprise attack, completely cripple him.
Both of them were concentrating on observing their opponent, each wanting to deliver a fatal blow.
As Minato's mind raced, a method suddenly appeared in his head. He felt that if this method worked, he wouldn't need to carve the Flying Thunder God formula on Uchiha Hai's body.
"Wind Release—Tornado Fist!"
A large amount of chakra gathered in his hand, and then an invisible fist of wind rushed towards Uchiha Hai.
Uchiha Hai dodged it with a flicker, but he didn't notice that at the moment he dodged, Minato had left a Flying Thunder God formula on the spot.
Of course, Uchiha Qinghui also saw Minato squat down for a moment and touch the ground, but he didn't notice anything wrong, so he didn't remind Uchiha Hai.
Even Shikaku didn't know why Minato would suddenly reveal such a big opening. Among those present, only Kushina knew clearly that Minato was carving a Flying Thunder God formula on the spot.
For over half a month, she had also been training with Minato, so she naturally knew the principle of the Flying Thunder God Technique. It was the legendary space-time ninjutsu.
After Minato finished carving the formula, he deliberately left a very large opening on the spot, an opening that could be fatal.
"Good chance!"
Seeing Minato's opening, Uchiha Hai immediately rushed forward. He first threw a few more shuriken to prevent Minato from retaliating, then took out a kunai and stabbed fiercely at Minato's neck.
Minato's acting was also very good. He quickly retreated a step or two, his face showing an expression of extreme horror.
"Minato, be careful!" Shikaku, who didn't understand the situation, was horrified and immediately rushed forward.
But in the next second, he was stunned. Because just as Minato was about to be stabbed in the neck, with a "swoosh," his entire person disappeared.
Not only was he stunned, but Uchiha Hai was also completely stunned. Impossible! How did this guy disappear? The Body Flicker Technique also required hand signs, and he definitely didn't have time to form any just now, he was sure of it.
But he couldn't see it. Shikaku, however, saw it. One moment he was on the brink of life and death, and the next, he appeared behind Uchiha Hai. It was simply unbelievable. How on earth did Minato do it?
"Not good!" Uchiha Hai finally sensed that something was wrong because he felt movement behind him, but he couldn't react at all.
"Konoha Great Whirlwind!"
Appearing behind the unprepared Uchiha Hai, Minato used all his strength to deliver the most powerful Konoha Great Whirlwind, aiming for Uchiha Hai's spine. If it was broken, Uchiha Hai's life would probably be over.
Perhaps Tsunade could heal it, but with the grudge between the Senju and Uchiha clans, it was unlikely Tsunade would treat Uchiha Hai.
"Thump, thump, thump!"
In order to make it a one-hit kill, Minato kicked several times in rapid succession, not giving Uchiha Hai the slightest chance to resist.
"Crack."
The sound of a bone breaking rang out, exceptionally loud in the training ground.
"Aargh!" A miserable scream came from Uchiha Hai's mouth, as unbearable pain spread from his back.
It should be known that although Minato's taijutsu might be lacking in variety, his strength was very powerful.
After all, his physique development was close to 90%. With his full-strength strike, breaking Uchiha Hai's spine was all too easy.
"Not good!"
The Hokage's direct Anbu, who was hiding in the shadows, appeared with a swoosh. He hadn't expected the outcome of the battle between the two to be decided in such a short time.
Minato's Flying Thunder God Technique was too fast and too sudden, leaving everyone unable to react.
Even the Jonin Anbu in the shadows was too late to rescue him.
He rushed over to check Uchiha Hai's injuries, and his heart sank. His spine was broken. If he didn't receive treatment, he would be crippled for life, able to do nothing but lie in bed.
Thinking of this, the Anbu immediately took Uchiha Hai to the medical department. He didn't bother to reprimand Minato. As a direct Anbu, he naturally knew that Minato was Lord Jiraiya's disciple and that the Hokage was paying close attention to him.
This time, he was sent to protect both sides from fatal harm, but it was more like protecting this little guy. He could guess the Hokage's thoughts quite accurately.
"Bastard! How dare you! To beat Cousin Hai like this, the Uchiha clan will definitely not let you go!"
The brothers Uchiha Qinghui and Mahui pointed at Minato with pale faces and scolded him.
Then, very comically, they ran away directly, not daring to say another word, afraid that Minato would give them a beating too.
