Implanted Illusion

What?

Hōzuki Mangetsu stared in surprise at the mad scientist before him.

As a transmigrator, he naturally knew the true nature of Chakra.

But he hadn't expected Amachi to have suspected it too. The man was not to be underestimated!

Amachi smiled faintly. "That's the principle behind Illusionary Technique. The caster can use Chakra to confuse the target's five senses, creating hallucinations. In other words, the two parties can be connected through Chakra. Ninjutsu uses Chakra to control the five elements, while Illusionary Technique directly affects the mind. Chakra is the channel that connects people's minds."

So that was it!

Though Hōzuki Mangetsu knew the story, he had never studied the subject in as much detail as Amachi had.

"What did you mean by implanted Illusionary Technique, Amachi?"

He asked, puzzled.

Uchiha Itachi had once implanted Amaterasu in his younger brother's eye, which had astonished him. Later, when Obito had given Kakashi his power so he could use Susanoo, Hōzuki Mangetsu had been at a loss for words.

But after hearing Amachi's explanation, he was beginning to understand.

Amachi seemed a little excited. Like Orochimaru, he was a scientific fanatic who loved researching everything.

Over the years, he had conducted many experiments in secret. Implanted Illusionary Technique was just one of his research projects.

"If Chakra is the bridge between people, then, in theory, Illusionary Technique can also be cast by implanting it. As long as you connect the Chakra of both parties, you can use that bridge to alter the other person's will."

Amachi adjusted his glasses and explained unhurriedly, "I've conducted many experiments, and they've proven this theory. Contact through Chakra can alter another person's will. Unfortunately, once the Chakra that was transferred runs out, the illusion naturally ends. So, to permanently change someone's will, you have to periodically send Chakra into the subject. That's the only way to keep the illusion effective."

A spark of inspiration flashed through Hōzuki Mangetsu's mind, and he immediately understood something.

Perhaps Obito Uchiha could control Yagura for this very reason. With Obito's strength, implanting an illusion inside Yagura shouldn't have been a problem. Once it took effect, all he had to do was send Chakra into Yagura at regular intervals to maintain control.

That was also why Obito Uchiha had to stay near Yagura so often: he needed to keep sending Chakra into him.

Understanding this, Hōzuki Mangetsu felt a surge of excitement. He had found a way to break Obito's illusion.

"Here's a perfect opportunity. Don't you want to give it a try?"

Amachi smiled. "I can implant an illusion in this man's mind. When he wakes up, he'll be your puppet. And as long as you periodically send Chakra into him to maintain the illusion, you'll be able to control him completely without worrying about him turning on you."

He had discovered the technique of implanting an illusion by chance, and even Orochimaru knew nothing about it.

That was why he'd had the confidence to break with Orochimaru.

Hōzuki Mangetsu seemed like a good partner, too. Naturally, Amachi wanted to demonstrate his value.

With Amachi's help, Hōzuki Mangetsu soon managed to implant an illusion in Chukichi's mind.

At the same time, the Cursed Seal activated, and Hozuki Mangetsu's Chakra flowed continuously into Chukichi's mind.

The permanent illusion was complete.

"Lord Mangetsu!"

When Chukichi woke, he knelt before Hōzuki Mangetsu and gazed at him with heartfelt sincerity.

Chukichi's memories from the past few years had been erased and replaced with new ones that Hōzuki Mangetsu had given him.

In those memories, Hōzuki Mangetsu was his master and had saved his life many times. He had to remain loyal to him.

Perfect!

Hōzuki Mangetsu gazed at it all in amazement.

Implanting an illusion wasn't complicated. All it took was connecting the Chakra between two people, and the simplest way was through physical contact.

Since Chukichi was unconscious, he couldn't resist. Amachi had naturally wiped his memories and successfully implanted the illusion.

He had once been ordered to do the same thing to Anko. As a result, even now she couldn't remember her time in the Land of the Sea.

As soon as the illusion was implanted, the Cursed Seal automatically sensed Hozuki Mangetsu's Chakra, and the two were immediately connected.

The Cursed Seal itself contained his Chakra. Because it had absorbed Natural Energy, the Chakra within the seal would never run dry.

If an implanted illusion was a light bulb, then the Cursed Seal was a power source—one that could provide energy forever. In other words, once someone with an implanted illusion was marked with the seal, they became Hōzuki Mangetsu's puppet for good, until death.

This was practically a weakened version of Kotoamatsukami.

Hōzuki Mangetsu had thought Kotoamatsukami could only be used after integrating Hashirama Cells, but now it had appeared early by sheer coincidence.

The Sharingan combined with the Cursed Seal could completely replicate the effect of Kotoamatsukami.

Now that he understood the principle, he could use the power of the Sharingan to implant an illusion himself.

"Could you do me a favor?"

Hōzuki Mangetsu smiled at Amachi.

Amachi nodded.

They were partners now, so helping each other was only natural.

"Help me transplant an eye!"

As he spoke, Hōzuki Mangetsu took out a container. Inside lay a Sharingan.

It was Uchiha Shisui's eye.

"The Sharingan!"

Amachi nodded.

The Uchiha Clan's Sharingan was a valuable thing. People from Konoha coveted its power, so it was only natural that Hōzuki Mangetsu wanted one transplanted.

"Sure!"

For an elite medical ninja like Amachi, transplanting an eye was child's play.

Before long, Hōzuki Mangetsu's right eye had been replaced with a Sharingan!

When he opened his eyes, his reflection in the mirror had three Tomoe.

In an instant, his Chakra began to circulate, and his perception increased dramatically.

He suddenly clutched his right eye, cold sweat running down his face.

"An increase in power comes with risks. Since you're not an Uchiha, using the Sharingan will put a strain on your body."

Amachi adjusted his glasses and spoke unhurriedly.

He was a research fanatic and wasn't particularly interested in power.

As expected!

Just as I thought!

Hōzuki Mangetsu wiped the cold sweat from his face and lowered his right hand.

After a while, he gradually adapted to the Sharingan.

"Amachi!"

Hōzuki Mangetsu suddenly called out.

"What?"

Amachi raised his head, caught off guard. The moment he saw Hōzuki Mangetsu's Sharingan, he knew something was wrong.

He desperately tried to close his eyes, but the Sharingan of the strongest Illusionary Technique user was not so easy to escape.

Soon, Amachi gave up resisting, his eyes turning vacant.

He had fallen under the Sharingan's illusion.
