Facing the flying Kunai, Uchiha En quickly formed hand seals.
"Bang~"
A puff of smoke appeared, and a wooden stake replaced Uchiha En's position.
"Thud, thud, thud~" All the Kunai stuck into the wooden stake.
At the same time, Uchiha En used the smoke to instantly rush towards Asuma.
Uchiha En didn't use teleportation but rather Body Flicker Technique because teleportation would inevitably carry some spatial fluctuations, and Uchiha En wasn't sure if the Third Hokage could sense these fluctuations, so he chose to use Body Flicker Technique for the advance.
In battles between Genin, the Body Flicker Technique still offers a significant advantage. Genin who master this technique are much stronger than their opponents in terms of speed and explosive power.
When Asuma Sarutobi saw Uchiha En instantly disappear into the smoke, he realized that Uchiha En had already mastered the Body Flicker Technique.
Asuma Sarutobi immediately threw a smoke bomb on the ground to conceal himself, then determined Uchiha En's approximate location by the direction of the smoke's flow.
Asuma Sarutobi formed hand seals: "Fire Release: Flame Bullet!"
"Did he use the smoke's flow to determine my approximate location? He's got some skills! As expected of the Third Hokage's son," Uchiha En thought to himself as he saw the huge fireball flying towards him.
Of course, while he was thinking, Uchiha En's hands weren't idle. He quickly formed hand seals, and a huge fireball spewed from his mouth to meet Asuma Sarutobi's Flame Bullet.
Fire Release: Great Fireball Technique vs. Fire Release: Flame Bullet.
Both are C-rank, both are Fire Release, and even the Ninjutsu effects are similar. The winner would depend on who infused more Chakra into the technique.
"Boom~" The two fireballs collided, and the heat wave instantly dispersed the smoke.
The onlookers could finally see the situation on the field clearly.
The Third Hokage glanced at the two fireballs and knew that Asuma had lost this time.
Although Uchiha En's Great Fireball was launched later, it clearly had more Chakra infused and was more powerful than Asuma's Flame Bullet.
This showed that Uchiha En's Chakra control ability was significantly stronger than Asuma's.
The facts were exactly as the Third Hokage had thought: Uchiha En's Great Fireball Technique broke through Asuma's Flame Bullet.
Then, Uchiha En used the aftershock of the Great Fireball Technique's explosion, and with a Body Flicker Technique, disappeared from Asuma Sarutobi's sight.
After Asuma dodged the Great Fireball's explosion, he found that Uchiha En had disappeared. He quickly looked around but couldn't find Uchiha En's figure.
Asuma Sarutobi hesitated for a moment, then decided to force Uchiha En to reveal himself.
He leaped high, formed hand seals again, first released Fire Release: Phoenix Sage Fire Technique, and immediately followed with Wind Release: Great Breakthrough. The Wind Release amplified the Fire Release, and the enhanced Phoenix Sage Fire Technique rained down around Asuma.
After continuously releasing three Ninjutsu, Asuma Sarutobi's Chakra was largely depleted.
However, Asuma Sarutobi thought that Uchiha En's situation was similar. Although the Body Flicker Technique consumed less Chakra than a typical C-rank Ninjutsu, Uchiha En had just infused more Chakra into the Great Fireball Technique.
By this calculation, Uchiha En should have also used three C-rank Ninjutsu, putting them on equal footing, so he had nothing to fear.
As several fireballs fell, Uchiha En's figure was discovered by Asuma Sarutobi. He pulled out a shuriken and shot it at Uchiha En at a very tricky angle.
Then Asuma Sarutobi saw Uchiha En's pupils turn red.
Using the Sharingan's dynamic vision, Uchiha En pinpointed the Kunai's attack angle and dodged Asuma Sarutobi's shuriken with just a slight shift of his body.
Seeing this, Asuma Sarutobi gritted his teeth and decided to use his trump card Ninjutsu.
If one shuriken couldn't hit, what about ten, or a hundred?
Asuma threw another handful of shuriken at Uchiha En, then his hands quickly formed hand seals: "Ox-Dog-Dragon-Rat-Dog-Boar-Snake-Tiger."
The Third Hokage on the stage frowned as he watched Asuma form the seals, thinking: "These seals are for shuriken Shadow Clone? When did he learn that?"
As Asuma finished forming the seals, the shuriken he had thrown instantly multiplied into dozens.
The Third Hokage was a little disappointed. His shuriken Shadow Clone Technique could instantly create tens of thousands of shuriken for attack.
Asuma had only learned the basics, and coupled with insufficient Chakra, he could only create dozens of shuriken, unleashing less than one percent of the shuriken Shadow Clone's power.
"If this is Asuma's trump card, then he's probably going to lose," the Third Hokage thought.
Dozens of Kunai shot at Uchiha En from all directions, seemingly blocking all of Uchiha En's escape routes.
Asuma thought that no matter how strong the Sharingan's dynamic vision was, Uchiha En should be unavoidable now, and the teacher or the old man should step in to save him.
Thinking this, Asuma turned to look at the teacher and the Third Hokage, but found that they had no intention of intervening.
Asuma's heart sank, and he quickly turned back to look at Uchiha En.
Facing these Kunai, Uchiha En neither dodged nor flinched, allowing the Kunai to hit him.
"Splash~" Uchiha En, who had been pierced like a porcupine by the Kunai, turned into a puddle of water.
"Water Clone! How could this be..."
Asuma Sarutobi's words were cut short when he suddenly felt a chill at his neck. He turned slightly and found Uchiha En's Kunai already at his throat, a pair of scarlet Sharingan eyes staring at him without any emotion.
"When did you use the Water Clone?" Asuma Sarutobi asked, unwilling to accept defeat.
"Right in the interval between your Phoenix Sage Fire Technique and Great Breakthrough Technique. At that time, all your attention was on preparing to continuously release the Great Breakthrough, and the fireballs from the Phoenix Sage Fire Technique blocked part of your vision.
I used that opportunity to form the seals. If I stood at that angle over there, my Water Clone should have been very clear to see." Uchiha En pointed towards the Third Hokage and the teacher.
Asuma Sarutobi gave a wry smile upon hearing this. No wonder they hadn't intended to intervene earlier; so that was what happened.
"I surrender, Uchiha En, you win!"
Uchiha En smiled slightly, put away his Kunai, and his Sharingan disappeared.
The students were all surprised to hear Asuma Sarutobi surrender.
"Asuma actually lost?" Shiranui Genma said with a look of surprise.
"Has Uchiha En become so much stronger after activating his Sharingan?" Kurenai Yuhi added.
"It shouldn't just be the Sharingan's doing, right? Uchiha En's Ninjutsu and Taijutsu are also very powerful, and he, like Hyuga Asana, has learned the Body Flicker Technique," said Ibiki Morino.
"I didn't expect Uchiha En to be so strong!" Obito said with a complex tone.
The people in Class Two were also discussing animatedly.
Apparently, Uchiha En defeating Asuma Sarutobi surprised them too.
This was the Hokage-sama's son, after all!
