Chapter 689 Complete Mastery

D-class personnel Naruko screamed extremely miserably, but researcher Naruko and guard Naruko were unmoved. Guard Naruko raised her baton and threatened viciously: "It hurts more if your hand is blown up or your head is smashed." , you choose one!”

As he spoke, he raised his baton as if to smash it. The poor D-class personnel Naruko could only shed tears and continue to test the unstable version under the instructions of the researcher Naruko and the pressure of the guard Naruko. Rasengan.

Such a scene is happening in every human experiment team. D-class personnel are constantly dying in various strange ways and disappearing into smoke, only to be quickly replenished by new clones.

Jiraiya really can't stand it. This human experiment process is so inhumane!

However, he couldn't stop it. Those D-class personnel who were sacrificed innocently were all Naruto's shadow clones, which meant that Naruto was abusing himself, which is called self-abuse. If he is self-abuse, no matter how cruel he is, no one else can control him.

In a short period of time, at least hundreds of D-class personnel were injured or killed due to Rasengan explosions. The scientific research girls in white coats would carefully record the data of each failure, and then propose another set of parameters for the D-class Personnel hottie test.

Jiraiya gradually began to see some patterns. These experimental groups were not trying to find out the correct way to roll the Rasengan through trial and error, but more like collecting methods to make the Rasengan fail.

Some failure methods are very extreme. The initial explosion that cannot maintain stable rotation is actually the most common. A more outrageous failure method is to roll the rasen pill into a spiral cake and try to compress the spherical pellet into a thin piece. Naturally, after it was compressed to the limit, the high-pressure air flow flew out from the edge, cutting the D-class hottie in half.

There are also many D-class personnel who were forced by the hot girl researcher to mix other chakra changes into the Rasengan. The Rasengan added with Fire Release Chakra exploded into fireballs, igniting the D-class personnel into running torches. Or add the Thunder Release Chakra, and the D-class personnel will be scorched black by the electricity...

Batch after batch of D-class personnel were consumed, and the recording paper of the scientific researcher in charge of recording became thicker and thicker. Finally, the data collected from the human experiment finally reached a certain threshold, and the scientific research leader Hot Girl gave an order, and all D The hot girl who was a senior officer and the hot girl who was a security guard disappeared into white mist.

"Now, summarize all the data to form the final experimental report!"

The hot girls in scientific research entered the recorded data into the computer one after another, and the supercomputer started a new round of digital simulation. Large sections of code flowed down the computer screen like a waterfall.

Once everything was done, all the hot girls and the computers they had channeled turned into white mist and disappeared.

"Phew... so tired..."

Naruko, a literary girl, swayed, let out a long breath, and murmured with exhaustion on her face. She supported Jiraiya weakly, closed her eyes and concentrated, and didn't make a sound for a long time.

"Hey, are you okay?"

Jiraiya asked worriedly.

Naruko waved her hands, took a deep breath, opened her eyes, her blue pupils were gleaming, and regained her energy. She smiled proudly and said: "Now, I have completely mastered the Rasengan. It took a total of One hour and twenty minutes!”

"is that a lie?"

Jiraiya actually vaguely believed her words. Her series of incomprehensible actions just now seemed to have some deep meaning, and they were by no means aimless.

Naruko, a literary girl, didn't talk nonsense. She stretched out her palm and said softly: "This is the Rasengan MK1 prototype!"

As soon as she finished speaking, the air flow in her palm rotated, and a blue ball of light as big as a broad bean was formed. It quickly expanded to the size of a crystal ball, causing the surrounding air to surround it and form a cyclone.

She made the most basic spiral pill with such ease, it was as easy as eating and drinking!

Jiraiya looked at the blue chakra cyclonic light ball floating in the palm of the literary girl, and swallowed unconsciously. She actually mastered the A-level ninjutsu like the Rasengan in more than an hour!

Back then, Jiraiya spent three days learning the Rasengan and then proudly showed off to Minato Namikaze. Minato Namikaze was not surprised, but it made Jiraiya feel even more disappointed.

Now, Jiraiya finally understood why Namikaze Minato was not surprised. It turned out that for a person with genius genes, learning the Rasengan in three days was really an ordinary speed, but his son only took more than an hour to learn the Rasengan. Easy to do!

"This is an improved version of the Rasengan MK2, a Rasen Shuriken that incorporates changes in the Wind Release Chakra."

The literary girl continued, and as she spoke, a high-speed whirlwind formed around the blue sphere in her palm, which looked like a rapidly rotating shuriken.

He casually threw the spiral shuriken into the woods, and the exploding wind blade cut off a large thick tree. The literary girl raised her arms with her palms facing the sky, making a lifting gesture.

"Rasengan MK3, the Daitama Rasengan that increases the chakra input of the Rasengan and enlarges the size of the prototype in equal proportions."

In her raised palm, the Rasengan expanded rapidly from the size of a pea to the size of a crystal ball, and then continued to expand into a huge spherical shape of about one meter in diameter.

In view of the power of the Otama Rasengan, Naruko did not throw it out to test, but skillfully controlled the rapidly rotating chakra to slowly disintegrate.

"Rasengan MK4, a mini Rasengan that increases surface pressure and shrinks in size without changing its power!"

"Rasengan MK5, mixed with Fire Chakra, a powerful fire Rasengan that will explode after collision!"

…

After showing Jiraiya five different improved types of Rasengan, the literary girl's chakra was almost exhausted, and she said with a tired face: "There are many feasible improvements in the data simulation, such as turning the two shafts in opposite directions. , the Tai Chi Rasengan with chakra properties similar to the Rasengan combined into one. The Hurricane Thunder Rasengan with the addition of Thunder Release chakra. I can’t use it with my current strength.”

After taking a breath, Naruko continued: "There are also some digital virtual models that are theoretically feasible but difficult to verify in practice, such as the fission spiral pill with purified uranium added to the core, the internal pressure is greatly enhanced after the collision, and the temperature rises rapidly. , a fusion spiral pill that adds hydrogen isotopes to the core of the fission spiral pill..."

Jiraiya didn't quite understand what the theoretical models Naruko was talking about, but he felt vaguely uneasy. He felt that if Naruto really researched it and tested it, something big would happen. He quickly said: "That's enough, that's enough. It's already very difficult." Okay, I believe you have completely mastered the Rasengan!"

The exhausted literary girl could no longer hold on, and fell into Jiraiya's arms. With a pop, she turned back to her original form of little yellow fur, and just curled up in his arms and fell asleep.

Jiraiya was stunned for a long time, then slowly sat down and changed Naruto into a more comfortable sleeping position. Looking at the child sleeping in his arms, he had mixed feelings in his heart. When this little devil fell asleep, he really looked like a Angel.

Recalling his focused, passionate, and even fanatical eyes when he was studying the Rasengan, Jiraiya didn't know what he would become in the future.

Learn Rasengan in one hour, not just learn it, but completely master it!

This kind of ninjutsu talent is unique in the ninja world. It is many times better than the child with the Samsara Eye that he taught back then. Could it be that he is the savior predicted by the elder Toad?

However, this child is not an angel. He has just shown his dark side of using any means to achieve his goals. If he wants to learn ninjutsu, he will not hesitate to play with people's hearts and take advantage of others. He is ruthless when researching the Rasengan and forces the shadow clone to conduct cruel human experiments. No sympathy for D-class test specimens...

Is he a demon or an angel?

Should we teach it with all our resources, or kill it as soon as possible?

This is really a difficult choice!
