Uchiha You slowly formed seals and placed sealing techniques on Uchiha Shisui's head, chest, back, and lower abdomen.

Dense sealing runes extended everywhere, covering every inch of Shisui's skin, even his fingers and toes.

But Uchiha You did not stop. With his superb skills, he continued to apply seals on top of the seals, creating a layered three-dimensional seal.

More and more sealing runes spread everywhere, until Uchiha Shisui turned completely black, with only the whites of his eyes and teeth still white.

He rolled his eyes, watching Uchiha You busying around with anxiety and fear, and he looked so funny.

Uchiha Shinin almost laughed out loud when he saw it, and had to suppress it with tea.

But the smile on the old man's face had been seen by Shisui, and his eyes became even more resentful, which completely amused the old man, making him spit out the tea in his mouth and laugh out loud while coughing.

Uchiha You couldn't help but want to laugh when watching the interaction between the old and the young, but considering Shisui's face, he still quickened the pace of his hands and completed all the work of the sealing formation.

When the last rune of the sealing technique was cast, the layers of sealing techniques began to work. Because there were many layers superimposed on each other, the natural energy in operation affected each other, and even reflected the sealing rune in gold.

The originally pitch-black Shishui suddenly turned into golden Shishui. Layers of wheel-shaped halos surrounded his body, slowly rotating and floating up and down.

This brilliant look lasted for a few seconds, and then all the gold and halo suddenly shrank, finally converging to the top of Shisui's head, hidden under his thick hair.

When the last ray of golden light faded, Uchiha Shisui in front of him turned back into a fair-skinned and handsome young man.

Uchiha You was very satisfied with his technique and asked, "It's done, Shisui, do you feel any changes?"

Uchiha Shisui did not answer. He even seemed a little dizzy. After waiting for a long time, he finally came to his senses and breathed a long sigh of relief.

He said to Uchiha You: "Brother You, this is amazing, this is amazing! What is this?"

Uchiha You smiled slightly and said, "This is the system."

Uchiha Shisui & Uchiha Shinin: "?"

System is a word that has not yet appeared in the ninja world. Uchiha Yu can only explain that this is a name he made up. Its specific function is to monitor Uchiha Shisui's physical condition.

The most important function is to manage his practice progress and assign various tasks according to the progress.

Uchiha Shisui guessed: "Mission, like a ninja's mission?"

Uchiha You nodded and said, "It does look like one, and if you complete the system task, the system will also give you a reward."

Shisui asked excitedly, "Brother You, what are the rewards?"

Uchiha You did not answer his question, but laughed: "Haha, figure it out yourself, anyway, they are all good rewards."

Uchiha Shisui left behind the excitement test system, said hello to old man Xin Yin, and then Uchiha You left Shisui's house.

Afterwards, he went straight to Uchiha Ayumi's house to check on his progress in practicing the three basic methods of true teachings.

Unlike Uchiha Shisui, Ayumi's training progress is much slower. It cannot be said that there is no progress, but it can only be said that it is not worth mentioning.

Moreover, this kid is only a few months younger than Uchiha Yuu, and is almost four times as old as Shisui, so his perception has declined a lot.

In addition, he has awakened the Three-magatama Sharingan and has more than enough chakra in his body. Now it seems that these have increased the threshold for his practice.

This also means that the test version of the system is not applicable to Uchiha Bu Shi.

Because Uchiha You used natural energy as a drive, Uchiha Ayumi even found it difficult to maintain this large-scale three-dimensional sealing technique.

After a careful inspection, Uchiha Yuya could only shake his head and sigh helplessly, giving up the idea of ​​adding an additional system to Bu Shi.

He said to Bu Shi: "You can only practice harder now and slowly build a solid foundation. I have to go back and think of a way to tailor a new system for you."

Uchiha Bushi was very honest. Facing a system he had never heard of, he did not even ask questions. Instead, he thanked him earnestly, "Thank you for your trouble, clan leader."

Uchiha You nodded and went home.

While waiting for the Hidden Mist Village to provoke the Hidden Leaf Village, he designed a real system based on the captured and sealed gods, the kind that is standard for time travelers.

According to the principle that human nature is selfish, once people get the system and get a taste of the benefits, they will definitely keep the secret carefully.

By spreading systems with feedback effects, Uchiha Youneng will unknowingly extend his tentacles into the ninja world and establish a real big data analysis system on the Wuliang. He will truly control the entire ninja world.

More importantly, the ninjas who accept the system will eventually be tamed by the system's tasks and become members of the Fourth Calamity Corps directly controlled by Uchiha Yu.

This force is more powerful than money and more direct violence.

Unless the Sage of Six Paths jumps out of the Pure Land and personally participates in the fight, no one can compete with Uchiha Yu in the Ninja World.

However, the first step of this plan has encountered problems on the test version of the system.

Taking into account that all chakra in the ninja world has an owner and the goddess of the rabbit, Kaguya Ōtsutsuki, has absolute control over chakra, Uchiha Yuu specifically determined that natural energy is the driving force of the system.

After all, as long as it is a living thing, it can gather a considerable concentration of natural energy. This is the instinct of orderly life.

In his design, the system can be driven by human's own natural energy, without any additional investment from him.

This design was successfully implemented on Uchiha Shisui, but it failed completely on Uchiha Ayumi due to the interference of chakra.

Uchiha You was very worried: "I can only use the dual drive of chakra and natural energy. Normally, I consume chakra, and switch to natural energy when chakra is insufficient."

Miwa Masayo was the designer of the system task. She naturally participated in the design of the system throughout the whole process. At this time, she asked curiously: "You, what you said makes sense. Can it be realized?"

Uchiha You replied: "There is no problem in achieving it. In fact, the activity and controllability of chakra are much better than natural energy, and the difficulty of achieving it is much lower than natural energy."

Miwa Masayo suddenly didn't understand. She looked at Uchiha You and asked, "Since there is no problem, what are you worried about, meow?"

Uchiha You said helplessly: "Compatibility, my lovely three-tailed little Rika, the system I made now is incredibly large, it's so big."

He said frantically: "How can I use a sealing structure that can't even fit a body as big as an adult?"

The tabby cat immediately wilted. She couldn't solve such a problem.

Uchiha You was mad for a long time, and finally lowered his head helplessly: "I can only trouble my brother Uchiha Shisui."

"Only by modifying and iterating the system that runs on him, and slowly reducing the redundant sealing techniques, can we finally achieve compatibility between the two."

Even Miwa Masayo felt a little embarrassed about this idea. When he first practiced immortal arts, he experimented with the three basic methods on Shisui, and improved them bit by bit through Shisui's feedback.

Now he had to trouble Uchiha Shisui to be a test subject. The tabby cat covered his eyes with a pair of white paws to express his embarrassment.

Uchiha Yuu sighed for three minutes, then wiped his face and said, "Okay, forget about it, and start working!"

Miwa Masayo sighed and said, "I knew you would shamelessly say this, meow. I..."

Uchiha You turned around and asked, "To repay Shisui, I decided to make him a nice meal. Would you like to come with me, Rika-chan?"

The tabby cat jumped up and followed him: "It's not enough to cook one meal. If you want to make something, you should cook it every day. By the way, You, what delicious food are you going to cook?"

Just as Uchiha You was working hard to upgrade the system from the beta version to version 1.0, the news of the death of the Third Raikage spread throughout the ninja world.

The Kage of the Hidden Cloud Village died in battle, and the situation in the ninja world was naturally shaken.

The Hidden Cloud Village and the Hidden Iwagakure Village mobilized their own troops, and the two sides were on the verge of a fight and confronted each other with all their might, no longer caring about the Hidden Leaf Village and the Hidden Mist Village.

The Fifth Mizukage of the Hidden Mist Village, Kaguya Hamura, was completely left alone halfway. He faced the embarrassing situation of having no way out whether he moved forward or backward.

In the Hidden Mist Village, in the Mizukage's office, a strategic meeting was held in a depressing atmosphere.

The Fifth Mizukage took out a letter and showed it to Yuanshi and others.

"The Fourth Hokage of Konoha Village, Orochimaru, sent me a personal letter in which he asked us to recognize the situation, give up meaningless resistance, and admit defeat to Konoha Village."

"Only in this way can the war end and we avoid being killed."

The master was an old and experienced man, and had even seen Uchiha Madara's arrogance and domineering behavior. He had no reaction to Orochimaru's letter and was seriously thinking about the next strategy of the Hidden Mist Village.

But the newly elected leader of the Seven Ninja Swordsmen, the Watermelon Mountain Pufferfish Demon who wields the broadsword Samehada, could not tolerate it.

The fat ninja was furious, pointing at the letter and cursing, "The Leaf Village is too arrogant. No matter how strong they are, they can't make us surrender with just a piece of paper!"

"No matter how arrogant Orochimaru is, he should fight with us. Otherwise, who would surrender? Who dares to surrender?"

In the conference room, all the jonin were nodding their heads, and even the master agreed with this statement.

Except for the Kirigakure clan, almost all the ninja clans in the Hidden Mist Village came from the Land of Fire. They were driven out of the Land of Fire by the founders of Konoha Village, Uchiha Madara and Senju Hashirama.

The action of being expelled was not gentle at all, and there was a blood feud between them.

The reason why the ninja village of the Hidden Mist was able to be brought together by the First Mizukage was definitely due to its hatred for the Konoha Village.

In the two subsequent wars, the war between the Hidden Mist Village and the Konoha Village was the bloodiest, especially between the Hidden Mist Ninja and the Uchiha Clan, which was full of blood and tears.

It's the same in this war.

In the past two years, tens of thousands of ninjas from the Hidden Mist Village have died at the hands of Konoha ninjas.

If the Hidden Mist Village withdraws from the war and admits defeat just because of a letter from the Fourth Hokage, whoever dares to agree will become the public enemy of the Hidden Mist Village ninjas and will surely die in the Hidden Mist Village.

The master nodded and said, "Xiguashan is right. We have to fight. Even if we lose in the end, we have to let Konoha Village know that the bones of the Kirigakure ninja are tough!"

Kaguya Hamura agreed, "Master Yuanshi is right. This letter does not mention the conditions for surrender. If we agree to it, it will definitely be extremely harsh."

"Then let's fight!"

"We have defeated Konoha Village and frightened them. We have made Konoha Village pay a heavy price in blood. We have made the Fourth Hokage feel distressed and willing to accept the peace terms we proposed!"

The Watermelon Mountain Pufferfish Ghost stood up, raised his hands high and cheered loudly: "Fight, my sword is thirsty, it needs the nourishment of blood!"

Biwa Juuzou stuck out his tongue, licked the beheading sword, and chuckled, "It's great that I can finally kill a ninja from Konoha."

The Fifth Mizukage Kaguya Hamura stood up and ordered loudly: "All families, departments, and units, prepare for war. In three days, we will attack the land of the Land of Fire and go straight to Konoha Village!"

"yes!"

The Fifth Mizukage shouted again: "The Seven Ninja Swordsmen!"

Biwa Juzo, Xiguashan Pufferfish Demon, Kurishan Kushimaru, Tongcao Yabairen, Muli Shinpachi, Kurochu Raiga and Nashida Tamon each held a big sword in their hands. They stood up when they heard the sound and looked at the Mizukage with their sharp eyes.

Kaguya Hamura said with a smile: "I heard that you claimed that the seven of you can kill any Kage if you join hands. Prove to me that you can kill the Fourth Hokage Orochimaru."

The Seven Ninja Swordsmen raised their swords and cheered.

"Don't worry, Mizukage-sama. We will definitely cut off Orochimaru's snake head!"

"Orochimaru is nothing, we can definitely kill him!"

Kaguya Hamura smiled and nodded, then looked at his family and said, "The Kaguya clan finally has a Mizukage. I ask everyone to do their best to prove to the Hidden Mist Village and the entire ninja world that the Kaguya clan is strong enough to be a Mizukage!"

"Don't worry, Mizukage-sama. The ninjas of the Kaguya clan will definitely be at the forefront of all the Kirigakure ninjas!"

When these fanatical Kirigakure ninjas left, the Mizukage, the Master, and the little girl named Mei Terumi beside the Master were the only ones left in the Mizukage's office.

The Master sighed and said, "Lord Mizukage, do you have a chance of winning this time?"

Kaguya Hamura smiled and replied, "Of course not."

"Master Yuanshi, I have not been carried away. I know very well that this war is just a demonstration by our Kirigakure to Konoha Village."

"I will lead the Hidden Mist Village to attack with all our strength and let the Hidden Leaf Village know how powerful we are. But I will also stop the war in time and try my best to preserve the vitality of the Hidden Mist Village."

The Master nodded with satisfaction and said appreciatively: "The Fifth Mizukage is truly wise. I am relieved that you know what is going on."

Then he sighed, "It's unfortunate for the Hidden Mist Village. Ever since the death of the first Mizukage, Byakuren-sama, the second and third generations have not been very competent."

"After much difficulty, the Fourth Mizukage was a suitable leader, but he was framed by Uchiha Madara and caused more damage to the Hidden Mist Village than the previous two generations."

"Fortunately, you suddenly stood up in this critical moment. This shows that the Hidden Mist Village is not doomed to perish. It's really good."

Suddenly, the master threw his crutches aside, bowed deeply to Kaguya Hamura, and his hands almost fell directly to the ground.

He choked up and said, "Lord Mizukage, the Hidden Mist Village is at a critical juncture of life and death. I leave everything to you. I will do my best to support you."

Kaguya Hamura said solemnly: "I will do my best, please rest assured, Master Yuanshi."

The order for war spread, and the entire Kirigakure Village was in an uproar.

Momochi Zabuza also began to prepare with joy. He had specially made a big sword that was very similar to the beheading sword.

If a war breaks out with Konoha Village, the Seven Ninja Swordsmen, as the backbone of the Hidden Mist Village, will definitely be the main force to set foot on the land of the Fire Country.

This satisfied the prerequisite that Uchiha You promised to kill Biwa Juzo.

Judging from the battle record of this Konoha ninja, Biwa Juzo is definitely dead.

But Zabuza was inexplicably feeling strange at the moment. He was a Kirigakure ninja and was about to follow the Kirigakure Village to wage war against the Hidden Leaf Village.

However, at the Shinto Council meeting, the powerful ninja of Konoha Village promised that he would help Zabuza to kill the senior ninja of the Hidden Mist Village, Biwa Juzo.

Such a contradictory and confusing relationship between the enemy and us made Zabuza completely confused.

The fighting ninja, who already had a poor brain, gave up thinking before his brain was boiled and decided to act according to the simplest principles.

Biwa Juzo is definitely an enemy, but he cannot do anything himself, so he can only let the Konoha ninja kill him.

The Konoha ninjas are also enemies, and they will just start fighting when they meet.

It's so simple.

After thinking it through, Zabuza no longer had any worries and happily prepared combat equipment and supplies for survival in the wild.

The war order of the Hidden Mist Village is public, and spies from various countries lurking in the Hidden Mist Village have received the intelligence.

But the order was given so suddenly that before all the spies had a chance to transmit information to the outside, the Kirigakure Ninja had already set off.

The fifth Mizukage Kaguya Hamura's clan members, the Kaguya clan's ninjas were the first to set off. They boarded the family's large ship and were the first to set sail, heading west for the Land of Fire.

The ninjas of the Kirigakure clan led thousands of Kirigakure ninjas and set sail in the second batch.

They will not attack the east coast of the Fire Kingdom directly, but will bypass the Whirlpool Kingdom and the Tea Kingdom, land near the River Kingdom, and attack the south of the Fire Kingdom.

This is a flanking harassment force whose goal is to attract the attention of Konoha Village and also to attract some Konoha ninjas to move south to reduce the pressure on the main force's attack.

The third and final fleet to set off was the main force of the Kirigakure ninja. A total of 6,700 Kirigakure ninjas boarded the large ship and followed the Kaguya clan, rushing towards the Fire Country.

From the decision to launch a war to the entire Kirigakure Ninja army's attack, it took less than 12 hours.

The Hidden Mist Village really acted decisively this time, and the execution was so quick and efficient that it was amazing.

Yuanshi naturally didn't need to go into battle. The girl he brought with him, Mei Terumi, was a key protected person, so he didn't need to go into battle like Zabuza Momochi, who was the same age as him.

They stood on the rocks near the harbor and watched the Kirigakure fleet go away.

Mei Terumi asked, "Master Yuanshi, is this war doomed to fail?"

The Master nodded and replied, "Yes, with Orochimaru and that Wood Release Ninja here, we can't win."

"But in order for the Hidden Mist Village to continue to exist, we have to fight even if we know we will lose."
