Warlock Invasion of Naruto.

“This…” Amado’s eyes widened.

Genetic modification is no challenge for him, and simply enhancing the mental and physical energy of a few people is not difficult either. But when Bai Yu mentioned it, the workload was far too enormous, and he probably wouldn't be able to accomplish it.

Moreover, the differences between individuals are neither huge nor small; when it comes to a specific individual, genetic modification still needs to be adjusted.

"I will replant the sacred tree."

Bai Yu knew what Amado was worried about, so he added.

"Replant the Divine Tree?! Wouldn't that mean..." Amado's face showed shock. The reason he wanted to kill Isshiki was because he knew Isshiki's purpose. If the Divine Tree were planted, the vast majority of people in the ninja world would suffer, and it might even lead to the extinction of humanity.

"I'm not particularly interested in Chakra Fruits. I just want all humans to have chakra. That way, the differences between individuals will be reduced. Then you just need to research a gene-modifying drug and slowly vaccinate the entire population," Bai Yu continued.

As he spoke, he took out a storage scroll and tossed it to Amado.

It contains his research findings on gene modification; the subsequent research was left to Amado himself.

As for providing blood to make Amado a member of the White Feather bloodline, this can be used as a reward later, as not just anyone is qualified to share his blood.

"Yes, Lord Baiyu." Amado respectfully accepted the scroll from Baiyu's hands.

"Obito, go back to Akatsuki now. It's your turn to act alongside Orochimaru. If Nagato cooperates well, I might spare his life. If he doesn't, Kodama will help you finish him off."

With that, Bai Yu took out a palm-sized glass bottle and tossed it to Obito.

The glass bottle was filled with a light green nutrient solution, and an eyeball with a pale purple concentric circle pattern floated inside, with its end still attached to the fascia.

"Yes!" Obito bowed respectfully, then used Kamui to teleport.

"Then I'll set off too."

Orochimaru nodded to Shiraha, then grabbed Amado and opened a portal to leave.

"White Feather." At this moment, Kushina looked like she wanted to say something but hesitated.

"What's wrong?" Bai Yu smiled. "Is there anything we can't say to each other?"

"With our strength, we could easily sweep through and unify the ninja world. Why go through all this trouble? Besides, starting a ninja world war would result in more deaths than a direct unification. Wouldn't that be a bit... cruel?"

Kushina couldn't help but ask. In fact, she had wanted to ask ever since she learned about Shiraha's plan, but at that time the main problem was dealing with Isshiki. Now that Isshiki's problem had been solved, she finally couldn't hold back anymore.

"Don't worry, this matter won't involve ordinary people. As for the ninjas of the Five Great Nations, they were born for battle, so this is the best outcome for them. As long as the Five Great Ninja Villages exist and there are still restrictions between large and small countries, oppression and war will never end." Bai Yu explained, "Therefore, from now on, only one country will be enough, and that is the Land of Whirlpools!"

"The reason for going to such lengths is not for the ninjas of the five great ninja villages, but for the benefit of the general public."

The combined population of all the ninjas and villagers in the five great ninja villages wouldn't exceed two million, but the world's ordinary population is in the hundreds of millions. That's what we need to strive for.

"The Land of Whirlpools must act as a savior, enabling the masses to stand up again and gain their support. Only in this way can everyone willingly become citizens of the Land of Whirlpools and strive for this common nation."

"There are too many ordinary people in this world struggling to make ends meet."

Bai Yu sighed.

Faced with the Otsutsuki clan and unknown extraterrestrial civilizations, even Jonin, Kage-level shinobi, or even Super Kage-level shinobi in the eyes of ordinary ninjas are basically of little use.

Therefore, it was inevitable that ninjas would disappear from the historical stage.

What Bai Yu plans to develop in the future is a biotechnology system built upon chakra and the Divine Tree.

A new, relatively fair order, led by him, without war, will be established.

The majority of people in this world are ordinary citizens, so the imperial system is the most suitable new system for building a powerful technological empire.

"Yes..." Kushina couldn't help but sigh. In her youth, she had traveled through the ninja world with Shiraha. Many small countries were in ruins after the Ninja World War, and the lives of the lower classes there were like living in hell. That's why Kushina was worried that reigniting the Ninja World War would make the vast majority of the lower classes suffer even more.

However, Kushina was relieved after receiving Shiraha's assurance, because more than 30 years had passed since they met when they were six years old, and Shiraha had kept every promise he made to her and had never lied to her in this regard.

As long as ordinary people are not widely affected by the war, Kushina's inner unease will be eliminated.

As for the ninjas of the Five Great Ninja Villages, no matter how many die, she will not be soft-hearted. She has no good feelings towards Konoha, let alone the other ninja villages. The world of ninjas is inherently cruel.

When Uzushio Ninja Village was destroyed, none of the five great ninja villages could escape responsibility. Even if they did not directly intervene, they were all involved behind the scenes.

Any ninja who dares to obstruct the arrival of the new era will be dealt with by Kushina herself without Shiraha even lifting a finger.

......

July, Konoha Year 60.

In less than a month, several shocking events occurred that rocked the ninja world.

In Iwagakure, the Four-Tails Jinchuriki, Rōshi, was attacked and went missing, as was the Five-Tails Jinchuriki, Han; the Third Tsuchikage, Ōnoki, was furious.

In Kirigakure, Utakata, the Six-Tails Jinchuriki, is attacked and goes missing; the Fourth Mizukage, Mei Terumi, is furious.

In Kumogakure, the Two-Tails Jinchuriki, Yugito, and the Eight-Tails Jinchuriki, Killer Bee, were attacked and went missing. The Third Raikage, A, ordered the entire Kumogakure to begin searching for Killer Bee and Yugito throughout the entire ninja world.

In Takigakure, the Seven-Tails Jinchuriki, Fu, is attacked and goes missing.

Konoha Village, with only one pseudo-Nine-Tails Jinchuriki, Naruto Namikaze, and the Fourth Hokage, Minato Namikaze, who was skilled in space-time ninjutsu, did not encounter any attacks.

In less than a month, all six Jinchuriki of the five great ninja nations disappeared, which led to the Kage of the five nations uniting together.

Soon, everyone turned their suspicious gazes towards Uzushio Village, because Jinchuriki were among the strongest ninjas in the world, and there weren't many ninjas who could capture a Jinchuriki without even being able to call for help. Even fewer ninjas could accomplish such a feat in such a short time; Shiraha and Kushina were among them.

However, just as various countries were sending envoys to the Land of Whirlpools, a tremendous battle broke out in the mountains not far from the village of Whirlpool Ninja, and the entire mountain range disappeared.

Soon, news of Bai Yu being severely injured by Orochimaru, a super S-rank rogue ninja, spread throughout the ninja world.

The fact that a top-tier medical ninja like Bai Yu could be severely injured and rendered bedridden is itself an unbelievable feat.

When the envoys from various countries saw the severely injured and unconscious Bai Yu, they all brought back this terrible news to the village.

At the same time, the Akatsuki and the Infinite Rings organization, two mysterious organizations, have emerged.

Soon, everyone learned that the kidnapping of the Jinchuriki was a joint operation by Orochimaru and the two major organizations.

Orochimaru was like a huge shadow looming over the entire ninja world.

......

The Land of Whirlpools.

The new Six Kage Tournament is being held in Uzushio Ninja Village.

At this moment, in the conference room of the central building of Uzushio Ninja Village, high-ranking officials from various countries gathered together.

Kushina, Chiho, Eito, Hizashi, Shisui, Minato Namikaze, Naruto, Sasuke, Itachi, Nawaki, Onoki, Kyoto, Kurotsuchi, Third Hokage A, Fourth Hokage A, Omoi, Mei Terumi, Zabuza, Chojuro, Chiyo, Ebizo, Temari, Kankuro, Mifune...

In addition to the ninjas from the five great nations of Konoha, Iwagakure, Sunagakure, Kumogakure, and Kirigakure, envoys were also sent from countries such as the Land of Rain and the Land of Iron.

As for the allies of the Land of Whirlpools, the Land of Demons, the Land of Birds, the Land of Snow, and the Land of Bears are all present and accounted for.

The Allied Shinobi Forces were officially formed, and Kushina, as the strongest, was elected as the leader of the alliance.

The group quickly began discussing battle plans.

"The number of enemies is unknown, but there should be quite a few powerful figures. Moreover, Orochimaru is the biggest problem. If we can't defeat Orochimaru, then there's no point in joining forces."

Onoki's way was neither yin nor yang.

As soon as he said this, most of the ninjas looked at Kushina, who was sitting in the first seat.

Kushina's face darkened upon hearing this: "I'll deal with Orochimaru. He dared to ambush Shiraha. If I find him, I will kill him with my own hands!"

“If Lady Kushina is going to deal with Orochimaru, then we’ll take care of the rest,” Onoki continued.

"Aren't you being a bit too confident, Onoki?"

A disdainful voice suddenly rang out in the conference room.

Everyone looked at each other, searching for the source of the sound.

"Up there!"

Everyone looked up and saw a ninja wearing a whirlpool mask standing upside down on the roof.

"Who goes there?!"

All the ninjas present became alert, and some impatient ones even launched attacks directly, only to pass right through the opponent's body.

"What's going on?!"

"My attack!"

Obito landed lightly and stood on the conference table, looking down at everyone.

"Has that trembling brat from back then grown into the strongest ninja in Iwagakure now?"

Obito glanced indifferently at Onoki.

The familiar voice and tone made Onoki tremble and he suddenly stood up.

"Who exactly are you?!"

------

P.S.: Just to clarify, no matter how I write about the Fourth Shinobi World War, it's still primarily based on the anime's plot. Although the main characters have changed, the core storyline remains largely the same. A detailed account would easily fill twenty or thirty chapters, which would be quite padded. Therefore, I will skip most of the detailed events below. If you'd like to see those, I'll include them in the free bonus chapters as character arcs. For example, arcs like Danzo, Madara, and Orochimaru, using different perspectives. Or I might add some post-war developments.

[282. Chapter 260 The War of Unification (Part 4)]

Obito glanced at Onoki and said calmly, "Onoki, you don't even know...?"

boom--!

With a sonic boom, a crimson figure passed through Obito's body. Due to its high speed, the figure crashed directly into the wall behind the conference room, creating a large hole in the solid wall, which was over a meter thick.

Kushina flashed back into the arena.

Her body was surrounded by the crimson aura of the "Crimson Dragon Calamity" breathing technique, emanating a terrifying aura.

"You bastard..."

After missing her first attack, Kushina did not continue to attack Obito.

"how so?!"

"Even Kushina..."

"Just who is this guy?"

"Is this an illusion? But it doesn't seem like an illusion."

If the ninjas' previous attacks on the masked man failed to touch him, preventing everyone from making any rash moves, then Kushina's attack, which also failed to harm the masked man, left everyone in disbelief.
