Warlock Invasion of Naruto.

Orochimaru named this experiment "Cursed Seal," an experiment that could enhance a ninja's power and make him virtually immortal.

The cursed seal can be considered a supplement to his inability to learn the Ryuchi Cave Sage Mode, a degraded version of Sage Mode, a controllable Sage Mode.

Having experienced the Ninja World War, Orochimaru felt physically and mentally exhausted.

Even if Konoha wins the third Shinobi World War, he doesn't know if he will die in the future Fourth Shinobi World War. By then, he will probably be over fifty years old. He is afraid that one day he will become like his teacher, the Third Hokage, Hiruzen Sarutobi, because of old age.

Physical aging and decreased strength are very frightening.

But what's even more terrifying is that his mindset has changed. After losing his courage, he became hesitant and power-hungry. The stoic hero he once was is gone forever.

Orochimaru was not interested in power; he only hoped to explore the true secrets of ninjas and fully unleash the potential of the human body in his lifetime.

Limited time can only yield limited knowledge; only by living as long as possible, or even living forever, can one gradually explore the truth.

Orochimaru's only attachment to Konoha now is his hope that after becoming Hokage, he can change the current political landscape, restore the Third Hokage to his youthful state, and prevent a repeat of Sakumo's tragedy.

After that, Orochimaru only hoped to train his disciples well and protect Konoha.

In this way, he could dedicate his life to experiments.

"Yes, Orochimaru-sensei," Anko replied, quietly observing Orochimaru conduct his experiments.

Soon, Hongdou felt bored; she simply couldn't muster any interest in this.

However, this is a normal phenomenon.

Girls her age are either passionate about romance, idol worship, or spiritual practice.

For Hongdou, Orochimaru is her idol and role model.

After looking around the laboratory, Hongdou left and headed to the next room.

Orochimaru glanced at her but remained silent.

After a while, Anko returned to the lab and saw that Orochimaru had stopped his experiment. She couldn't help but ask, "Orochimaru-sensei, are there two bedrooms here? One is yours, and the other is that Yagami Shiroha's?"

Orochimaru was taken aback by this and nodded slightly, saying, "You should call him senior brother, just like Nawaki."

“But the villagers all say that Bai Yu… Senior Brother…” Hongdou hesitated.

"What are the villagers saying?" Orochimaru asked casually.

Red Bean: "Everyone in the village says he's a traitor."

Orochimaru: "What do you think?"

Red Bean: "I...I don't know."

Orochimaru: "You may have a chance to get to know him later."

Orochimaru fell silent as he spoke.

Red Bean noticed the change in Orochimaru's expression and felt somewhat complicated. It seemed that this senior brother, White Feather, held a significant place in Orochimaru's heart. When she went to the bedroom earlier, she found that both bedrooms were spotless, indicating that Orochimaru cleaned them regularly.

"I would never betray Orochimaru-sensei!"

Red beans symbolize the path of self-reliance.

Orochimaru stepped forward, gently stroked Anko's cheek, and smiled slightly: "You'll understand later."

"I will always follow behind you!" As if afraid Orochimaru wouldn't believe her, Anko continued to express her determination.

Orochimaru simply smiled without saying a word, then turned around and continued his "cursed seal" experiment.

The Earth Curse Seal is complete; now it is time to conduct the experiment on the Heaven Curse Seal.

Compared to the vague and unrealistic Wood Release experiments, the Cursed Seal can actually increase a ninja's strength, and the survival rate is much higher than that of transplanting the First Hokage's cells.

......

The Land of Bears is a small country located south of the Land of Demons and north of the Land of Wind.

This country is smaller than the Land of Demons, only about half the size.

However, within the Land of Bears, there is a ninja village organization called "Star Ninja Village," whose leader is known as "Star Shadow."

Of course, the title of "Star Shadow" was self-proclaimed by the Star Ninja Village, which is just self-aggrandizement and is not recognized by the ninja world at all.

Only the leaders of the five great ninja villages of the five great nations can be called 'Kage'.

Other ninjas, even those with Kage-level strength, cannot hold the title of Kage. Even Hanzo, who is known as a 'demigod,' is only referred to as the leader of Amegakure.

The mere weak Star Village of the Land of Bears probably has no more than a hundred ninjas, yet its leader dares to call himself Star Shadow. This is truly arrogant and ignorant.

However, even if some people dislike it, they can't do anything about Hoshigakure. The ninjas of this village rarely go out on missions, and the place where Hoshigakure is located is called 'Hell Valley'. It is situated below a cliff and is surrounded by poisonous miasma. Unless you wear full-body protective gear, going down into the valley is suicidal.

Small countries are not capable of entering Hell Valley, while the five great nations are capable of attacking Star Village, but there is absolutely no need for them to do so.

Therefore, even though the people of Xingnin Village proclaimed themselves the sixth greatest ninja village, no one paid them any attention.

At this moment, Bai Yu arrived at the top of a cliff and looked down.

The area below the cliff was shrouded in thick, yellowish-brown miasma, making it impossible to see the depth.

Even if the miasma wasn't poisonous, the near-right-angle cliff alone would make it difficult for ordinary ninjas to descend.

While walking on trees and water isn't considered advanced skill for Chunin and Jonin, if the cliff is too deep, even ordinary ninjas would find it difficult to maintain their balance and reach the bottom.

"Star Ninja Village?"

Bai Yu thought to himself that he had spent a month in the Land of Demons, discussing the specific details of the pharmaceutical company with Miroku. He also selected some talented people to teach medical ninjutsu and the basics of ninjutsu, while leaving Kodama in the Land of Demons to oversee the work and continue teaching students.

As for Sasori and Kakuzu, they will remain in the Land of Demons for the time being, and will leave once the situation stabilizes somewhat.

After all, given Kakuzu's personality, he definitely wouldn't be able to stay in one place without going out to make money.

To ensure the smooth establishment of the pharmaceutical company, Kakuzu also took out his savings of one billion taels of silver as the company's initial working capital.

Bai Yu has given the degraded versions of the "Vitality Potion" and "Deep Blue Potion" formulas to Miro, with Mu Ling assisting him.

With these two medicines, the pharmaceutical company will definitely be able to establish itself in the ninja world and rapidly expand its scale.

By the time it comes into the sights of major powers and arouses their covetousness, it has already become a force to be reckoned with.

Whether other countries want to get a share of the pie depends on Bai Yu's mood.

If the other side dares to use force, then we'll have to see how strong they are.

If pushed too far, Shiraha will simply transfer Kushina and the entire Uzumaki clan to the Land of Demons.

Near the Land of Demons are several small countries, including the Land of Stone, the Land of Birds, the Land of Swamps, and the Land of Bears. To the east are the Land of Rain, the Land of Grass, and the Land of Rivers. If these small countries could be united, their total land area would not be smaller than that of the Land of Water, one of the Five Great Nations.

As for military strength, once it has developed for a few years, it should not be underestimated.

Currently, Hanzo of the Land of Rain is the ally that Shiraha primarily wants to win over.

Of course, it's best to start with the easy things and then move on to the difficult ones, so Bai Yu first went to the Swamp Country, which also worshipped priestesses.

The leader of the Swamp Country immediately expressed his willingness to stand with the Demon Country and form an alliance with the Uzumaki Clan.

The same applies to the Bird Country and the Stone Country afterward.

Currently, Bai Yu has direct control over two countries: the Land of Demons and the Land of Snow.

Shion, the next generation priestess of the Land of Demons, is his bloodline, and Miroku will do his best to nurture her.

Kazahana Hayate from the Land of Snow is a clever person. She is now on the same side as Shiraha. Kazahana Hayate is more afraid of capsizing than Shiraha, so she has been cooperating with him wholeheartedly.

Thanks to the prestige of Kazahana Hayate and the military might of Shiraha and Kushina, the heavy industry of the Land of Snow has developed rapidly since the subjugation of the Snow Village.

If it weren't for the fear of attracting the attention of the five great nations too early and being vulnerable to retaliation, Bai Yu would have already prepared to put the chakra armor into the ninja market.

Shiraha takes the Land of Bears, the only small country surrounding the Land of Demons to have a ninja village, quite seriously.

However, the daimyo of the Land of Bears stated that he would respect the Third Hoshikage's opinion, so the alliance with the Land of Demons needed to be carefully considered. If the Third Hoshikage agreed, an alliance with the Land of Demons would be formed immediately.

Bai Yu didn't mind making the trip, so he arrived at Hell Valley, where Xingren Village was located.

A moment later, a figure with pale purple wings flew out from the miasma-filled valley below. With a gentle flap of its wings, it quickly arrived in front of Bai Yu and landed steadily on the ground.

"What is this?" Bai Yu's gaze sharpened.

The person who arrived was wearing a protective suit and a gas mask.

The other party removed their gas mask, revealing a beautiful female ninja with long red hair and a five-pointed star headband, who was about the same age as Bai Yu.

"Are you Yagami Shiroha of the Uzumaki clan?"

The female ninja asked.

"Yes." Bai Yu smiled slightly: "I've come to discuss the alliance."

"My name is Xia Rixing, and I am a Jonin from Xingnen Village. Please follow me."

As he spoke, Xia Rixing took out a storage scroll from his pocket and took out a protective suit and a gas mask from it.

"I can do it myself." Bai Yu saw Xia Rixing walking over with protective clothing and a gas mask and reached out to take them.

Xia Rixing smiled apologetically and said, "I'm sorry, but to keep it a secret, I need to blindfold you first. It's a rule when entering Xingren Village."

"I understand." Bai Yu nodded, letting Xia Rixing wrap his eyes with black bandages and then put a gas mask on him.

"Please follow me." Xia Rixing formed hand seals, and pale purple chakra wings immediately grew from her back. Then she hugged Bai Yu's waist and flew down the valley with him.

At this close range, Bai Yu was able to clearly sense Xia Rixing's chakra through his "sixth sense".

She exudes a special energy field, and there are two very different energy fields in her body, one of which is emitted by chakra.

Another special energy field emits extremely strong radiation. If one is exposed to this radiation for a long time, it can cause injury or shorten lifespan, or even death.

This strange energy field merged with Xia Rixing's chakra, but a considerable portion remained in her body.

"Is this why her chakra can materialize?"

Bai Yu thought to himself that he could sense a strong radiation coming from the direction of Xia Rixing's body, which was of the same origin as the radiation emanating from Xia Rixing's body.

It seems there's an unexpected surprise on this trip to Xingren Village.

This radiation would be fatal to ordinary people, and even to ninjas.

But wizards are themselves a collection of radiation, so they are not afraid of radiation at all, and even like it.

Now that Bai Yu has reached the level of a first-level sorcerer, he usually tries to restrain the radiation power emitted by his body, otherwise the radiation alone could kill an ordinary person.

Of course, a ninja's chakra is a powerful form of radiant energy, so when Bai Yu suppresses the radiation, contact with a ninja will not have any effect, as long as it is not intimate contact.

As for Kushina, her own radiation level was no weaker than Bai Yu's, not to mention that she also had the Nine-Tails, a super radiation-emitting creature, inside her, making her radiation level far stronger than Bai Yu's.
