Ninja World: I, Kisame Hoshigaki, am no longer human!

Tsunade stared at the live slug and spoke again. She was a decisive person; once she made a decision, she wouldn't change it.

"Lady Tsunade, are you really sure about this?"

The slug was both nervous and excited, and said softly, "You should know that once you choose to become my jinchūriki and merge with my chakra and consciousness, we will share your body and never be able to separate again."

"Of course I know. It's just like the Jinchuriki of the Tailed Beasts. It's not some unbelievable or strange thing."

Tsunade wasn't too bothered by this, since most of the other Jinchuriki were at odds with the Tailed Beasts within them, often vying for control of their bodies and even losing consciousness and going berserk. However, she and Katsuyu were friends for many years, and their future interactions would undoubtedly be harmonious, without any problems.

Therefore, Tsunade doesn't mind and is happy to share her body with the live slug, which can not only help it leave Shikkotsu Forest and gain freedom, but also give it all of the live slug's power to help her win the current war.

"Lady Tsunade, what do you think of Lord Kisame?"

After a moment of silence, the slug suddenly asked the question, which stunned Tsunade.

"What do you mean? Why bring up that bastard all of a sudden? If he hadn't dragged me into this mess, I don't know where I'd be living a carefree life right now," Tsunade said with dissatisfaction, getting angry whenever Kisame was mentioned.

What she never expected was what the live slug said next.

"So, you actually hate Kisame-sama, right? But I've already... fallen for him."

With her head bowed, like a shy young girl experiencing her first love, the slug murmured, "If Lady Tsunade becomes my jinchūriki, how do you plan to handle your relationship with Lady Kisame? If you hate him so much, I'll really feel very awkward."

“Live slug, you…”

Tsunade was dumbfounded, her jaw almost dropping in shock.

When Kisame first told her that he had fallen in love with a live slug at first sight and wanted to pursue her, Tsunade initially thought Kisame was a pervert.

I thought it was just a spur-of-the-moment thing, but I didn't expect that guy to be serious. In less than two years, he's already won over Kisame. You have to admire Kisame's action and perseverance.

It turns out that this kind of great love that transcends species really exists.

It took Tsunade a long time to come to her senses.

"Lady Tsunade, I know you can't accept this, so let's just let it go. If you're willing to fight for Kisame-sama's Hidden Mist Village, I will do my utmost to go to the battlefield and fight alongside you."

Seeing that Tsunade did not respond for a long time, the slug took the initiative to speak.

Tsunade remained silent for a long time, then sighed before finally speaking again: "Katsuyu, just as Kisame said, my body is a perfect match for yours, making me the most suitable Jinchuriki candidate in the world. If you don't choose me, who else can you choose as your vessel? Perhaps you'll have to wait decades, centuries, or even millennia. Moreover, only when we become one can we unleash our greatest power and defeat the Allied Shinobi Forces. Otherwise, we will have no chance of winning."

"But, what about Lord Kisame..."

"Don't mention that bastard!"

Tsunade clenched her fists abruptly, gritted her teeth, and yelled at the slug, saying impatiently, "I promise you, I'll try not to hate that guy so much anymore. If it really doesn't work, I'll just put my consciousness into a deep sleep, out of sight, out of mind. Then I'll hand over control of my body to you, so you can go on a date with him. Are you satisfied now?"

"..."

Faced with Tsunade's astonishing words, this time it was the slug's turn to be stunned. Could it really borrow Lady Tsunade's body and go on a date with Lady Kisame?

This is crazy.

But then I thought about it again. Lady Tsunade is almost forty years old this year, which is not considered young in the human world. At least most women her age are already married and have children who are already teenagers.

Barring any unforeseen circumstances, Tsunade, being an older single woman, will likely remain so, so there's nothing wrong with her lending her body to a live slug. After all, Tsunade doesn't have a boyfriend, so she won't be angry about it.

What are you thinking?

Seeing that the slug still didn't reply and instead seemed lost in thought, Tsunade realized that it was definitely not thinking about anything innocent.

"Ah, no, it's nothing."

The slug blushed, finally made up its mind, and mustered up its courage to say to Tsunade, "Lady Tsunade, I am willing to accept your invitation and transfer all my soul and chakra into your body."

"Okay. Then let's... get started quickly."

Tsunade took a deep breath and acted swiftly.

Previously, Kisame had already discussed the Jinchuriki ritual with Katsura, which was basically the same as the ordinary Tailed Beast Jinchuriki ritual, with no major differences. Moreover, Tsunade had also performed several Jinchuriki transplant surgeries with Kisame and was already very familiar with the relevant procedures.

Therefore, with the cooperation of both her and the live slug, completing their union was not as difficult as one might imagine.

Inside the Shibkushi Forest, the ceremony soon began.

Meanwhile, back in the ninja world, the troops of all the major ninja villages had finally assembled, and a vast army continued to rush to the front lines, marching into the Land of Water...

7017 k

235. The Fog-Hidden City Falls

The Second Five Kage Summit, held in the Land of Iron in Konoha in 49, was supposed to be for the purpose of achieving peace, but it ended up becoming the fuse for the Fourth Shinobi World War.

Following the death of Mizukage Kisame Hoshigaki, under the orders of the daimyo of the four countries of Fire, Wind, Earth, and Lightning, the four major ninja villages of Konoha, Amegakure, Iwagakure, and Kumogakure each assembled ninja forces ranging from several thousand to ten thousand, forming an allied army of fifty thousand.

There is only one goal: to conquer the Water Kingdom.

In Cloud Shadow Village, at Lei Ying Ai's command, more than 10,000 people signed up in just a few days to join the army to attack the Land of Water. This village has always revered strength and military power.

In Iwagakure, the Tsuchikage Onoki and his son, Kotsuchi, led eight thousand Iwa ninja eastward, passing through the Land of Fire, and joined up with the Konoha army.

Konoha's Hokage, Jiraiya, led his elite Jonin, Minato Namikaze and Hiruzen Sarutobi, along with elite ninjas from major clans such as the Uchiha, Hyuga, Ino-Shika-Cho, and Aburatsuka clans, plus geniuses like Kakashi and Might Guy, and even the assistance of the toad sages from Mount Myōboku—essentially their entire force.

In this attack on Kirigakure, the Konoha forces will be the main force, vowing to avenge the humiliation of the Third Shinobi World War and completely destroy Kirigakure.

Inside the tower in Yuyin Village.

"Yahiko, you take the vanguard and go there. These two men are at your disposal."

Nagato, seated in his wheelchair, gave instructions to Yahiko and then performed hand seals, summoning the Second Tsuchikage Mu and the Third Raikage once again using the Impure World Reincarnation technique. He then explained to Yahiko how to control the two.

These two people are worth ten thousand ninjas.

Yahiko's mission this time is twofold: firstly, to eliminate Kisame's henchmen and prevent the enemy from having any chance to make a comeback; secondly, and more importantly, to reclaim the Tailed Beasts, including not only the Two-Tails, Four-Tails, Five-Tails, and Eight-Tails that were previously stolen, but also the other Tailed Beasts of Kirigakure.

"Yahiko, you just need to hold off the people from the other three great ninja villages until I recover from my injuries. Then, I will personally go to Kirigakure and take all the tailed beasts into my possession."

Nagato said this.

After defeating Kisame, his next goal was clear: to collect the nine tailed beasts, revive the Gedo Mazo as the Ten-Tails, and then become the Ten-Tails' jinchūriki.

That day will be the day Nagato unifies the ninja world, bringing lasting peace to the world, and the day the Akatsuki's ideals are realized.

Yahiko nodded, and together with the Second Tsuchikage and the Third Raikage, quickly left Amegakure and headed to the front lines.

"Nagato, are you sure you want to risk your life and go to the Hidden Mist battlefield?"

Konan looked at Nagato's injured leg and said to him with a worried expression, "Now that Kisame Hoshigaki is dead, the other major ninja villages will definitely unite against you in secret. The scene at the Five Kage Summit may repeat itself. Don't underestimate those people, especially the ninjas of Konoha. Their foundation and potential are unfathomable."

"Don't worry, Xiao Nan, I've already thought of that."

Nagato sneered. He had long anticipated that Jiraiya, Onoki, and the others' next target would be to find an opportunity to eliminate him, otherwise they would probably have no peace of mind.

"So what's your plan?" Konan asked curiously, seeing that Nagato seemed confident.

"Of course."

Nagato smiled slightly and sighed, "I must say, the Second Hokage, Tobirama Senju, was a genius, and his greatest invention was this Impure World Reincarnation technique. Over the past year, I've sent the Viper of Ryuchi Cave to infiltrate various ninja villages, secretly searching for the graves of those historically powerful figures and stealing their remains. The Second Tsuchikage and the Third Raikage were just appetizers; my true trump card has yet to be revealed."

"Are there any ninjas even more powerful than those two? Could it be..." Konan was startled, several names flashing through her mind. In the history of the ninja world, those names were true legends.

“You’re right, it’s them. Once I recover from my injuries, I can use the power of the Rinnegan to summon their souls back from the underworld and easily manipulate them for my own use.”

Nagato gave a mysterious smile.

At that time, he wouldn't even need to personally intervene; his Edo Tensei army would be able to handle everything.

In this grand scheme of the ninja world, he will undoubtedly be the final winner.

Three days later.

The armies of the four great ninja villages officially assembled at the border and sailed towards the Land of Water aboard more than a hundred warships of various sizes.

Hidden Mist Village.

Faced with impending annihilation, Master Yuan ordered the immediate evacuation of all civilians in the village, including Yuki-onna, Mikiko, Sara, and others, who were transferred to a temporarily safe place under the escort of the Dark Guard.

The ninjas of Kirigakure will fight to the death with the village, until the last one falls.

Two days later.

The army landed on the border of the Land of Water, and after a brief rest, marched deep into the heart of the Land of Water, conquering cities and territories along the way with unstoppable momentum. Any Kirigakure forces that attempted to stop the army crumbled at the first contact, utterly powerless to resist.

In the end, wherever the army went, the Hidden Mist ninjas fled at the mere mention of their name. Some abandoned their identities and escaped to the borders of the Land of Water, while others fled back to the Hidden Mist Village and hid away.

Seven days later, the army arrived at Kirigakure and engaged in a final battle with the village's thousands of ninjas.

This was a war in which the disparity in numbers and strength was enormous.

The Allied Shinobi Forces had over 50,000 men, while Kirigakure had less than 5,000, less than a tenth of the former. Moreover, Kirigakure's elite ninjas were far fewer in number than the Allied Shinobi Forces, making it difficult for anyone to contend with a ninja like Minato Namikaze, let alone the Kage who hadn't yet made a move.

Looking down from mid-air, the Hidden Mist Village, shrouded in thick fog, was engulfed in flames and smoke, accompanied by shouts of battle, the clash of weapons, explosions, and screams of agony.

In this almost one-sided decisive battle, the defenses built by Kirigakure were easily breached, most of the village's buildings were destroyed, and the ninjas who fought desperately to resist the enemy, as well as the civilians who did not have time to escape, were massacred.

Corpses lay strewn across the fields, and blood flowed like rivers.

It was like a scene from hell.

Soon, surrounded by the Allied Shinobi Forces, the remaining Kirigakure ninjas were driven to the front of the Mizukage Building. With nowhere to retreat, they could only fight a final, tragic battle.

Whoosh.

Minato Namikaze, flashing yellow, calmly traversed the battlefield, wielding a trident-shaped kunai. Like a grim reaper, he brought down enemies wherever he went, and none could withstand a single blow from him.

Around him, Kakashi, Might Guy, and Uchiha Shisui also performed exceptionally well, each killing dozens of enemies and even engaging in a competition.

Like a ferocious beast, Matthias charged through the enemy ranks, repeatedly knocking down enemies with his fists and kicks, all the while counting aloud:

"98, 99, 100! Kakashi, I won!"

After kicking a Kirigakure Jonin away, he turned around excitedly and shouted to Kakashi, who was not far away, "Next time it's your turn to treat me to dinner!"

"Unfortunately, I've now defeated exactly one hundred enemies," Kakashi said calmly, retracting his blood-stained kunai as an enemy collapsed before him.

"Both of you are amazing. I guess I need to work harder too."

Shisui, whose kill count was lower than the two, smiled knowingly upon seeing this scene, his competitive spirit unusually ignited. No sooner had he spoken than his eyes flashed with a sharp light, and he instantly created dozens of shadow clones, who charged into the ranks of the Hidden Mist ninja and wreaked havoc.

The geniuses of Konoha, while cracking jokes, ruthlessly slaughtered their enemies, taking lives with their own hands.

Not far behind them, Jiraiya, Hiruzen Sarutobi, and the others watched with smiles on their faces as these young people rose into the mist on the battlefield, their eyes filled with satisfaction.

However, in wars where justice and evil, right and wrong are indiscriminate, one's own heroes are often seen as ruthless demons in the eyes of the enemy.
