Heavy rain poured down, and the Hidden Mist Village was shrouded in rain.

Although it was almost noon, it was as dark as night under the dark clouds. It was almost pitch dark and nothing could be seen a few meters away.

Zabuza, wearing a raincoat, entered the Hidden Mist Village through the gap in the wall.

After crossing the wall, he turned around and looked at the gap in silence for a long time.

Bai asked, "Mr. Zabuza, what's wrong with you?"

Zabuza sighed and said, "This is where I left the Hidden Mist Village after my last failed assassination attempt. This is the gap I dug with my own hands."

"But it wasn't this big at the time, and it was only big enough for me to pass through."

"After so many years, not only has no one come to close the gap, but it has widened to the point where vehicles can pass through."

Zabuza looked at the damaged features of the breach in the wall, as well as the footprints and wheel tracks scattered around it, and said with emotion: "The Hidden Mist Village can't even repair the wall anymore... It's really in decline."

The disappointment and regret in his words gradually turned into determination: "The controlled Fourth Mizukage is so terrible. Although I knew he deserved to die, I never thought he could bring disaster to the Hidden Mist Village to this extent. He must be killed today."

"Bai, help me block the others when the time comes."

"Mr. Zabuza, please feel free to fight. I won't let anyone get in your way."

Bai was still wearing white clothes today, which seemed a little dazzling in the dark rainstorm. Fortunately, the rain cloth that Zabuza carried with him was black, which wrapped his body.

After expressing their feelings, the two did not stop and walked along an inconspicuous muddy road towards the center of the Hidden Mist Village. After a faint chakra fluctuation, they completely disappeared in the dense rain curtain, as if they had melted into the heavy rain.

Ninja needs no introduction.

After successfully sneaking into the Mizukage building, Zabuza and Haku rushed directly to the Mizukage's office. After easily knocking down several Anbu from the Hidden Mist Village, he slashed open the door of the Mizukage's office with a single sword.

Zabuza saw the Fourth Mizukage, Karutagi Yagura, who had already picked up his coral staff and was looking coldly at Zabuza in front of the door.

The Fourth Mizukage sneered: "So it's you, Zabuza."

"I haven't seen you for four years. You've grown taller, but your brain is still as stupid as before."

Zabuza smiled and said, "Yes, it's been four years, Fourth Mizukage."

The Kirigakure Anbu in the office didn't care about the conversation between the two. They followed their duties, drew their weapons and rushed towards Zabuza.

This is the Mizukage's office, which is filled with barriers and precious documents. It is a situation where ninjutsu cannot be used under any circumstances, so these six ninjas were carefully selected to act as guards.

Zabuza didn't want to cause much damage here, but in such a small environment, being besieged by six ANBU who were proficient in physical skills and close combat, he had no confidence at all without using ninjutsu.

So he whispered, "Bai."

"I'm here, Mr. Zabuza."

A figure also wearing a white ANBU mask flashed out from behind Zabuza, stretched out his hand and pushed, and 12 ice cones shot out.

Each ice cone was precisely aimed at the heart and neck of the Kirigakure Anbu, forcing the Anbu to stop attacking and instead block and dodge.

But what shocked them beyond belief was that the 12 ice cones could actually turn in the air.

The 12 ice cones have a peculiar structure, with a noticeable thin part at the tail, which changes its trajectory by breaking itself.

The ice cones changed their trajectories and either bypassed the blocking weapons or re-aimed at the dodging ninjas, continuing to point at the vital points of the Kirigakure Anbu.

The Kirigakure Anbu suddenly launched an attack, and hastily responded to the counterattack. They were no longer able to respond for a third time, and could only helplessly be pierced through the vitals by the ice cones, dying on the spot.

This is how battles between ninjas go. In a split second, victory or defeat is decided, life or death is determined.

Whoever can make accurate predictions and responses will be the winner and survivor, otherwise he will die.

This is why intelligence is the first factor that determines victory or defeat in a ninja battle.

Zabuza sneaked into this place four years ago to carry out an assassination and experienced the fighting style of the Kirigakure Anbu.

That time, the Fourth Mizukage didn't even take action. It was the Kirigakure Anbu who alone beat Zabuza so badly that he had to flee in panic.

But he also learned the information about the Kirigakure Anbu and passed it on to Shiro.

After receiving the intelligence, Bai carefully designed a tactic and succeeded in one fell swoop, eliminating all the Anbu guards without triggering any barriers.

The Fourth Mizukage finally showed a surprised expression: "Bingdun? There is actually a descendant of the Snow Clan who has escaped the net."

"Haha, since you've brought it to me, I'll take your lives without hesitation."

Zabuza questioned, "Fourth Mizukage, your subordinates died in front of you, and you don't care at all?"

Goji Yagura did not answer. The slight surprise in his eyes had completely disappeared. He returned to his wooden look and waved the coral staff in his hand.

However, this weapon with a flowery hook did not attack directly, but instead created a wave of water.

Water Style: Water Rush

Even with the help of ninja tools, the unsealed ninjutsu was still so sharp that Zabuza Momochi and Haku were hit by the ninjutsu without warning and were knocked out.

The water wave even broke through the thin outer wall, forcing the two ninjas to the square outside the Mizukage Building.

But at the same time, the Mizukage's office also suffered a devastating blow. Almost all the barriers were triggered, and countless confidential documents and intelligence were flooded.

When they arrived at the square, Bai used ice escape to create an ice wall to block the water wave attack.

Zabuza stood behind Bai and said with emotion: "The Fourth Mizukage is really controlled by illusion. He doesn't care about the death of his subordinates, nor does he care about the loss of the Hidden Mist Village."

"It seems that the people who control him have a deep hatred for our Kirigakure, and are destroying it without disguising it."

Bai looked at the constant impact of the water waves and asked worriedly: "Mr. Zabuza, the Fourth Mizukage is very strong, are you sure you can win?"

Zabuza chuckled and said, "Don't worry, I am very confident now."

"Although Karuji Yagura's water escape technique is so powerful, he only has a large amount of chakra and has no skills in controlling it."

"If it was the Fourth Mizukage in his normal state, I would definitely not be able to defeat him, but a puppet controlled by an illusion is different. Its reaction speed is a beat slower, and its chakra is out of control after using a ninjutsu..."

"The Fourth Mizukage is so powerful, but his flaws are fatal. He is my best prey."

"Ha ha ha ha!"

Zabuza jumped up with a wild laugh, and the beheading sword in his hand cut through the air and raindrops. The round holes caused a low whistle sound and collided with the coral staff of the Fourth Mizukage who jumped out of the building.

The collision of two heavy weapons, which were rare in the ninja world but common in the Hidden Mist Village, sparked dazzling sparks and emitted a crisp golden sound.

Karuji Yagura turned the coral staff and activated the Water Style: Water Wave once again.

With the ground full of water, the air filled with raindrops, and with the blessing of the Three-Tails' chakra in his body, a huge wave like a big explosion rushed towards Zabuza.

A stiff sneer appeared on Karuju Yagura's boyish face: "A mere jonin dares to challenge a Mizukage like me. You really don't know how to live or die."

Zabuza also smiled. He tucked the beheading sword under his armpit and quickly formed seals with both hands. With just three seals, he completed the ninjutsu.

Water Style: Water Dragon Bullet Technique

Compared with the water waves created by big waves, the dragon-shaped water column created by the Water Dragon Bullet Technique is more powerful, and the Water Dragon Bullet easily penetrates the water waves.

The water dragon bullet penetrated the waves so suddenly that it almost hit Gojira Yagura, forcing him to roll and jump awkwardly, even rolling continuously to avoid the continuous water dragon bullet attacks.

The fourth Mizukage said in shock: "The technique of the second Hokage of Konoha Village, Tobirama Senju!"

"Zabuza, you actually learned the enemy's technique. Do you still have the self-respect of a Kirigakure ninja?"

Zabuza didn't care about the accusation of the Fourth Mizukage. He rolled his eyes and said, "You idiot who is standing behind and manipulating the Fourth Mizukage, where on earth did you come from? You actually asked such a question."

"Why is it that only Konoha ninjas are allowed to learn Kirigakure's techniques, yet it is considered shameful for a Kirigakure ninja like me to learn Konoha's techniques?"

"You can ask such a brainless question. I really doubt whether you have the ability to use illusions to control the Fourth Mizukage. The gap in intelligence is too big."

Zabuza frowned and said, "Could it be that the one who defeated the Fourth Mizukage and controlled him was someone else, and you who are controlling the Mizukage now are just a fool who inherited the control?"

Uchiha Obito: ...

Zabuza's words were like sharp arrows, especially the three words "stupid", "idiot" and "inheritance", which hit the vital points of the person controlling the matter behind the scenes.

After hearing Zabuza's words, the Fourth Mizukage's eyes changed drastically in just one second. First, there was surprise, then there was a struggle, then they returned to pure dullness, and finally they showed an unusually flexible movement.

The strange Fourth Mizukage asked, "How do you know that the Fourth Mizukage is controlled by an illusion?"

Zabuza thought about it, but didn't know how to explain it, so he responded with Uchiha Yuu's words: "Ah, I have a special information channel."

The weird Fourth Mizukage said: "Haha, if you don't want to tell me, then I'll chop off your head and then see what's inside your brain."

Zabuza sneered and said, "The Hidden Mist Village no longer has professionals who can explore the brain. Are you a ninja from the Hidden Leaf Village or the Hidden Cloud Village?"

"Haha, I get it, it's Konoha Village."

"This village has fewer traitorous ninjas than our Kirigakure, and they are all very powerful guys."

When the Fourth Mizukage and Zabuza were fighting and bickering, more Mist Village ANBU gathered around them, but they were all stopped by Shiro.

The square in front of the Mizukage Building had turned into a world of ice and snow. The heavy rain froze immediately when it hit the ground, forming sharp ice spikes.

These ice shoots were like bamboo shoots after the rain. They grew taller visibly, and then turned into ice cones, shooting towards the Anbu ninjas coming from all directions.

With the collapse of the Bloody Mist Village policy in the Hidden Mist Village, the Hidden Mist Village ninjas suffered heavy losses in internal strife and missions, which has seriously affected the quantity and quality of ninjas.

By the 60th year of Konoha, the long-term losses had caused the strength of the Hidden Mist Village to plummet. Even the best of the best of the Hidden Mist Anbu, the ninjas were not strong enough.

Under Bai's simplest control ninjutsu, these Mist Hidden Anbu were unable to break through and were blocked at the edge of the square.

Because the water on the bottom was frozen, the water-based ninjutsu that the Kirigakure ninjas were best at was severely suppressed. Not only were they unable to fight back effectively against the ice-based ninjutsu, they couldn't even dive close.

There were also some reckless Anbu ninjas who rushed forward desperately, but their protective water-style ninjutsu was shattered by the ice cones, and they were then turned into ice cone hedgehogs and finally into blood-red ice sculptures.

Although Bai controlled the entire square, the noise he made from fighting was not very loud.

The biggest commotion came from the Fourth Mizukage and Zabuza Momochi. Their ninjutsu confrontations were upgraded alternately and soon developed to the level of a large-scale ninjutsu showdown.

To be honest, Zabuza was not willing to fight like this, but the Fourth Mizukage was becoming more and more like a puppet and his reaction speed was getting slower and slower. At the same time, he could not use water-style ninjutsu well.

So Obito, who was manipulating him from behind, gave up his ninjutsu skills and simply used large-scale water-based ninjutsu, bringing the advantage of the Jinchūriki's large amount of chakra to the extreme, trying to crush Zabuza with great force and miracle.

Water Style: Water Tornado Technique

Water Style: Great Waterfall Technique

Water Style: Hurricane Water Vortex Technique

It was as if a tsunami had erupted in front of the Mizukage Building. Two-story-high waves crashed out one after another, directly turning the ice field in the square into the sea, and even submerging half of the Hidden Mist Village in water.

The huge noise alarmed the entire Hidden Mist Village. More and more Hidden Mist ninjas appeared. When they saw that one of the parties in the battle was the Fourth Mizukage, they joined the battle.

But more Kirigakure ninjas did not start a war directly, but chose to wait and see.

These ninjas secretly surrounded the two ninjas, followed the orders of the two ninjas, and surrounded the Mizukage Square.

Among the two leaders, one is a beautiful girl with thick long reddish-brown curly hair, wearing a blue off-shoulder long dress, and a pair of emerald green eyes. She is the future Fifth Mizukage Mei Terumi.

The other one is an old man with all his hair gone, a face full of wrinkles as deep as a canyon, and holding a snake-shaped cane. He is the oldest ninja master in the Hidden Mist Village.

Mei Terumi watched the fierce battle in front of her and couldn't help but sigh: "There is actually a ninja who has reached the level of a Kage-level ninja by using water escape technique. Master Yuanshi, do you know who this is?"

The Master's eyes hidden under his long white eyebrows were fixed on the periphery, looking at the white figure who was preventing the Kirigakure ninja from entering the square, and he didn't even look at the core of the most intense battle.

Hearing Mei Terumi's question, Master Yuan replied absentmindedly: "I don't know. I don't remember such a powerful ninja."

"If Hoshigaki Kisame hadn't defected and had stayed in the village to hone his ninjutsu, he might have been able to reach this level."

"Although water-style ninjas are very strong, they can never be a match for Karatachi Yagura. Except for Hoshigaki Kisame, no one can compete with the Fourth Hokage in terms of chakra volume."

The master raised his cane and pointed it in Bai's direction: "Compared to the water ninja, the ice ninja of the snow clan still has descendants, which is the real good news."

Mei Terumi took a look and nodded, "He is indeed an Ice Release Ninja, and his strength has reached the level of a Jonin. This is indeed good news."

"But compared to the Ice Release Ninja, adding a new Kage-level Ninja seems to be more important."

The Master smiled disapprovingly: "I don't know who he is, nor do I know what his position is. Besides, the presence or absence of this new guy will not affect our plan to overthrow the Fourth Mizukage."

"After all, Mei Terumi, your strength has surpassed that of the Fourth Generation. This is the basis for us to restore order."

"Even if this ninja doesn't show up today, we can still deal with the Fourth Hokage next year and make you the Fifth Mizukage."

The Master withdrew his gaze, half-closed his eyes and sighed, "I am actually worried that his appearance will alert Kujiya Yagura, and in the end we will lose the opportunity to carry out our original plan."

Mei Terumi asked, "Master Yuanshi, are we going to take action today?"

Master Yuan smiled indulgently and said, "Haha, listening to what you said, you can't hold it back anymore."

Mei Terumi nodded and said, "Yes, I really can't help it. I have waited too long. I have grown from a little girl to an old woman."

The master laughed and scolded: "Nonsense, you are only 27 years old, you are still young."

Mei Terumi's defense was instantly broken: "Master Yuanshi, isn't 27 years old almost 30 years old? I'm almost 30 years old, and no one will want me soon!"

Mei Terumi wanted to grab Master Yuan's neck and shouted, "Have you forgotten that my father was only 20 years old when he gave birth to me! 20 years old!"

"Old man! Just because you are old doesn't mean that 30 is not old!"

"Ah?" Master Yuan began to play confused: "What did you say?"

Suddenly, a white streak shot out from the center of the battlefield, and wherever it went, whether it was a sturdy house or a hard icicle, it was all cut like cheese.

Houses collapsed and icicles broke around Shuiying Square, and there was chaos everywhere.

The battle between Bai and the Kirigakure ninja had to be paused. Mei Terumi and the Master also widened their eyes and looked towards the core battlefield in the center of the square.

Just now, Zabuza revealed a flaw and was caught by the Fourth Mizukage's Water Style: Water Prison Technique. He took advantage of the opportunity when both sides were unable to move, played his trump card and achieved success in one fell swoop.

Although the Fourth Mizukage was not killed directly, his left arm was cut off, and along with the huge water ball, it was cut apart by Water Style: Water Cutting Wave.

The broken limbs caused the Fourth Mizukage's chakra to go out of control, and it instantly erupted into a violent storm, dispersing the rain, fog, and waves on the battlefield.

Just at this moment, the heavy rain that had lasted for several hours ended, and the dark clouds in the sky quickly dispersed, exposing the figures of the Fourth Mizukage and Zabuza to everyone.

The master was too old, and Zabuza had grown a lot taller in the past four years, so for a moment he couldn't recognize who he was.

But the young Kirigakure ninjas were impressed by this guy and recognized his identity at the first moment.

"It's Demon Zabuza!"

"Didn't the demon defect? ​​He actually came back and is fighting the Fourth Mizukage."

"Has Zabuza become so powerful?"

"Damn it, no matter how bad the Fourth Mizukage is, he can't be attacked by a traitorous ninja, right?"

"Hmph, I think it would be great if Zabuza could kill the Fourth Hokage."

"Asshole, do you also want to defect and become a rebel ninja?"

"With a Mizukage like this and a village like this, there's nothing wrong with being a rebel ninja."

Master Yuan couldn't help but close his eyes when he heard the voices around him, and sighed: "It's Zabuza. We can only follow him when he makes a fuss."

"Ming girl, go ahead and get rid of Goji Yagura today."
