Senbon Kill

The gushing torrent was like a silver dragon, charging towards its target. Although the Sand Ninja also unleashed a combination ninjutsu similar to a fire tornado, it was an unconscious combination of attacks. In just an instant, it was swallowed by the cold current carrying ice shards. Then, with undiminished power, it directly slammed into the Sand Ninja!

When the attack dissipated, the slightly disheveled Sand Ninja reappeared before Zhou Duan and the other three. Their chests were frozen by a block of ice, and their bodies were covered in tiny, cracked wounds. The Sand Ninja let out a painful roar, and through their bloodshot eyes, one could feel their infinite hatred for the four of them!

"Hiss, this guy is a bit strong!"

Hundred Palms' eyes widened:

"Our attack was a combination ninjutsu from the four of us, and it was already very powerful. He only suffered minor injuries?"

"He's a bit tricky, but a more interesting opponent!"

At some unknown time, Water Gate, who had always been gentle and humble, narrowed his eyes slightly, a hint of a ferocious smile appearing at the corner of his lips. With a reach, he pulled two special kunai, whose blades were a little longer than ordinary kunai, from his ninja pouch.

"I just observed that although his defense and ninjutsu are very strong, his close-quarters combat is really not good. Even the strongest defense and recovery have their limits. I'll go and try to chop him alive!"

"Hundred Palms, don't be too cautious, and Water Gate, don't be too eager!"

Nawaki looked at the two with relief:

"You both have the potential to become Hokage's assistants, which is great, but now it's time for me, the future Hokage... Ah!"

"Although our attack didn't cause much damage to the Sand Ninja, the situation on their end isn't much better!"

Zhou Duan kicked away the clowning Nawaki and then spoke, "Did you notice? Although the wounds are small, they haven't healed yet despite the Sand Ninja's rapid recovery. This shows that our attack had a significant effect on him. As a Medical Ninja, I suspect our cold current attack caused a delay in his cellular recovery. And the most serious impact of our two attacks on him was on his brain. He hasn't attacked us at all since we finished our attack. I have an idea. We need to perform a combination ninjutsu attack again. This time, let's use our most powerful combination ninjutsu!"

"Understood!"

"Don't worry!"

"Got it!"

As the words fell, Zhou Duan and the other three began preparing their ninjutsu again!

"Earth Release - Fine Dust Mourning Bullets!"

Following Nawaki's low shout, thumb-sized earth bullets spat out from Nawaki's mouth, like bullets, whistling through the air as they rapidly flew towards the Sand Ninja!

"Fire Release - Great Fireball Technique!"

Zhou Duan's Great Fireball Technique caught up from behind. Under the burning flames, the earth bullets turned red, and their power suddenly increased!

"Wind Release - Great Breakthrough!"

Water Gate's rapidly blowing gust of wind suddenly arrived. Driven by the Wind Release, the temperature of the earth bullets rose again, showing signs of melting!

"Swish swish swish!"

With a few metallic whistling sounds, Hundred Palms directly shot kunai tied with Explosive Tags in front of the Sand Ninja. As the combination ninjutsu from behind arrived, over ten powerful Explosive Tags detonated simultaneously!

Its power was like a meteor impact, its momentum like lava breaking through a stream. Countless faintly red, molten earth bullets, accompanied by the explosions, directly bombarded the Sand Ninja, who had only just begun to brew his ninjutsu. Its name:

"Eight Thousand Blazing Divine Fire Great Burial!"

The power of combination ninjutsu was immense. Although it was only an attack unleashed by four Genin, it was still very formidable. However, after the attack, the result that appeared before everyone's eyes was not very good!

Due to Zhou Duan and the other three's attack, the Sand Ninja was forced to fall to the ground, covered in burn marks from the intense flames. He spat out a mouthful of blood, which dripped from the corners of his mouth, and one of his wings was burned off halfway. However, although the Sand Ninja's injuries were somewhat tragic, they were not fatal. What was even more terrifying was that the wounds on his body were still rapidly recovering!

"Damn it, no way!"

Hundred Palms said indignantly, looking at the Sand Ninja, "This guy didn't even finish casting his ninjutsu just now, and our attack interrupted him. Even a normal Chunin would have lost half their life taking this attack. His defense is too high!"

"Not only that!"

Water Gate tightened his grip on his kunai. "Perhaps it's because we used a Fire Release-based ninjutsu just now, which canceled out the delayed recovery speed caused by the Water Release and Wind Release earlier. This guy's recovery speed has increased again!"

"Hmph, a guy like this who only attacks and has no brain..."

Nawaki contemptuously belittled the powerful Sand Ninja opposite them, "With firm belief, we will definitely achieve victory!"

"Nawaki, can you put that belief aside for now? Talk when you actually have some strength, okay? The opponent has already started casting ninjutsu. Captain... Huh?"

Halfway through his sentence, Hundred Palms instinctively felt something was missing. He looked around and immediately noticed Zhou Duan was gone. He quickly activated his Byakugan and exclaimed in surprise, "Holy crap, why is the Captain behind the Sand Ninja?"

That's right, Zhou Duan was indeed behind the Sand Ninja. As soon as the four's combination ninjutsu finished, Zhou Duan had already moved behind the Sand Ninja. For every gain, there is a price; this is an unchanging truth in the ninja world for thousands of years. Even forbidden ninjutsu is not omnipotent. While the instantaneous increase in combat power is indeed formidable, the drawbacks of the ninjutsu are magnified infinitely, and its side effects are even more powerful!

From the very beginning, Zhou Duan had been constantly analyzing the Sand Ninja's weaknesses. Although the Sand Ninja's hearing had degenerated, and his reason had been lost, turning him into a monster that only knew how to randomly cast ninjutsu, sacrificing only these two drawbacks was completely insufficient to gain such powerful Chakra reserves, rapid recovery speed, and defense!

Coupled with the vibration caused by the Explosive Tags in the recent ninjutsu, which made the Sand Ninja spit out a large mouthful of blood, Zhou Duan had a rough guess as to what the Sand Ninja's weakness was!

"Is the inside a weak point!"

Zhou Duan, hidden behind the Sand Ninja, watched as the enraged Sand Ninja prepared to unleash ninjutsu on Water Gate and the other two again. He reached for the ninja tool pouch at his waist and took out a special Senbon, several times thicker than ordinary Senbon.

Seeing the ninjutsu taking shape in the Sand Ninja's mouth, Zhou Duan immediately leaped up and charged rapidly towards the Sand Ninja. The short distance of more than ten meters was covered in an instant. His hands clasped together, leaving only his middle and index fingers to hold the Senbon, he thrust it rapidly towards the Sand Ninja's posterior:

"Experience the taijutsu secret art passed down for centuries by Konoha!
