Crossover in the Anime World

Pure Blue Chakra is a special chakra that only a ninja like Itachi can use in the world. Because it is a completely special power, it is obviously different from other chakras. This book "Pure Blue Chakra Application" tells the difference and changes.

Sasuke quietly hid the book in his arms, preparing to borrow it home and read it.

After cleaning all day, Naruto and Sakura were as tired as dogs. Only Sasuke still had a sullen face, as if his expression would not change even if the sky fell.

The salary of a ninja is still good. Naruto will save his salary. He basically has no other expenses except food. The clothes he wore were brought by the Sandaime for Naruto, and on the back of Naruto's coat was the Uzumaki family's logo. If you can't find a place to spend money, saving money is undoubtedly the best way, just in case. Naruto's attitude towards money is surprisingly conservative.

"Okay, today's work is over. We will meet at the training ground at the east end of the village at seven o'clock tomorrow morning. We will have a new task." Kakashi was basically lazy today.

"Ah, it's finally over. Isn't this very different from the ninja life I imagined?" Haruno Sakura stretched her body. She was really exhausted this day: "I don't know what kind of tiring work I will have tomorrow. It’s getting late, see you tomorrow, Sasuke.”

"Sakura, see you tomorrow." Naruto came over to say goodbye.

"Naruto, you were lazy and slept for half an hour at noon today. You must make up for it tomorrow." Sakura was pleasant to Sasuke, but she didn't have a good face towards Naruto.

Fortunately, Naruto didn't care. Rather than isolating him with cold violence, Sakura had a bad attitude but at least refused to communicate with him, so Naruto would only think that Sakura was a good person, and the more hateful she was, the better.

"Sakura, see you tomorrow." "Also, you poker face, see you tomorrow too." Although Naruto was tired, he was still very fulfilled today. It was the first time he collaborated with other people to complete a job, and he was still paid. . This was already a good start for Naruto.

Sasuke said coldly: "Goodbye." He turned and walked away. The three of them separated at an intersection and went back to their respective homes.

The Uchiha family is still responsible for the security. In fact, they were originally planning to arrange for Sasuke to join the security department directly, but Sasuke refused. If you join the security department, you will rarely have the opportunity to leave the village. Sasuke wanted to kill Itachi, so he chose to be promoted normally, so that he would have many opportunities to leave the village.

Hiding in the bedroom and quietly opening the book written by Itachi, Sasuke was immersed in another world. Sasuke knew that the man had mastered a special power. His fire ball was cyan. When Sasuke was young, he envied Uchiha Itachi's ninjutsu because Sasuke thought the cyan flame was beautiful.

But before Itachi's betrayal, Sasuke was still young and didn't know how this worked. After Itachi betrayed Konoha, everything about Itachi became taboo and the elders rarely talked about it. But by chance, Sasuke knew that many elders in the family were studying 'pure green chakra', the kind of power that belonged to Itachi. From that time on, Sasuke had always wanted to know what 'pure green chakra' was, but the elders kept silent and he knew very little.

So when he found this book in the library this time, Sasuke's heart almost jumped out of his chest. He thought the secret of 'pure green chakra' was hidden in this book.

However, this book does not teach you how to practice, but tells the story of Itachi's journey after becoming a disciple of Duran, and his experience in developing the 'Pure Green Chakra' ninjutsu through Duran's teachings.

In many places, the words are unclear, because isn't that what epiphany is? I don't know why I suddenly understand it. This feeling cannot be described.

"...The fire escape temperature released by pure green chakra is extremely high, three times that of ordinary chakra. Teacher Dulan said, 'Why not compress these flames to increase the temperature of the ninjutsu to the extreme.' Although teacher Dulan saw He seems to be approachable, but he has a strong arrogance in his heart. He likes the best, so he also hopes that we disciples can also be the best. I am the first student to cultivate the 'Pure Chakra', so He has high expectations for me. He will always come up with ideas. Those difficult problems that for us require painstaking efforts to solve are just sudden inspirations for teachers. He can easily realize them but hopes to improve through such tests. Our strength..." Sasuke hid in bed and read carefully. The content in the book is really just ordinary notes, recording many trivial things about Itachi and Koyuki Shisui's studies, as well as many of Duran's difficult-to-find inspirations.

However, under the guidance of Dulan, compressing the fireball technique was not a problem. With the efforts of teachers and students, S-level ninjutsu based on pure green chakra appeared.

The ninjutsu of linear destruction called "Fire Release: Blue Laser Beam" by Duran was born. It not only changed in shape but also in nature. It changed from blue flames to jetting radium rays. The maximum distance can reach three kilometers away. All targets within will be penetrated by Ninjutsu.

"... Teacher Dulan reminded us to learn the method of water release. There are many ninjutsu in water release that launch water at high pressure. He said that fire release can also be compressed and launched like water release. After a long period of testing, Shisui completed it first. I learned this ninjutsu called 'Fire Release: Laser Beam', because my flames were cyan, so later my ninjutsu was called 'Fire Release: Blue Laser Beam'..."

Just by reading, you can feel that Itachi was really happy during that period. He was learning new techniques with his teachers and brothers. His combat power was getting higher and higher day by day, and he was growing up visibly with the naked eye.

However, Sasuke felt chilled. What kind of enemy was he facing? It is unheard of to be able to release ninjutsu to kill the enemy from a distance of three kilometers. Thinking of his rubbish strength, Sasuke felt deeply defeated.

In the past few years, Sasuke didn't dare to slack off for a moment, but in the end he found that the distance between him and his brother not only did not shorten, but became farther and farther. This kind of loss almost made Sasuke bite the sheets.

The importance of teachers is reflected here. Shisui and Itachi both improved by leaps and bounds under the guidance of Duran. Even if they did not fully develop the blood chakra eye, they would still steadily move toward shadow-level strength.

The Sharingan is very strong, but the conditions for improvement are too harsh, and it will bleed at every turn.

The Sharingan, the Mangekyo Sharingan, the Eternal Mangekyo Sharingan, and then the Rinnegan. The condition for upgrading is to see a loved one die tragically to accumulate enough emotional impact to complete the surge in power. The condition for the Mangekyo Sharingan to rise to the Eternal Mangekyo Sharingan is to absorb the power of the brother's eyes. Otherwise, the more you use the Mangekyo Sharingan, the faster your eyes will go blind.

In history, only Uchiha Madara has opened the Eternal Mangekyō Sharingan, and even Uchiha Obito only has the Mangekyō Sharingan. And Itachi and Shisui who escaped were nothing more than three magatama.

And Sasuke has been practicing hard and now he can only open one magatama.

Now the Uchiha family can be said to be depressed and the atmosphere is depressed. Many people who have opened their eyes have slowly degenerated into ordinary eyes. The prestigious Uchiha Sharingan seems to have become a curse in this era, making the Uchiha clan hate their identity from the bottom of their hearts.

Because anyone with the last name Uchiha would have to bear the reputation of being a traitor to the clan, and the backbones of many clan members would be broken. The more this happens, the more angry Sasuke becomes. He must kill Itachi who has brought shame to the family.
