From the night of genocide, marching towards the strongest.

In addition, there is the Oni-ro bud, cultivated from special fusion cells that showed no rejection reaction, and the clones formed by combining the bloodlines of Kaguya's five direct descendants with her own cells as the core.

This made Ōtsutsuki Isshiki realize that this guy was doing something similar to what Indra was doing in modern times.

However, it was clear that Sasuke Uchiha had kept a secret from him and had not revealed all the secrets.

For the next period of time, Otsutsuki Isshiki kept his eyes on Yakushi Kabuto until yesterday when he held the fusion ceremony.

"This is..."

Following the other's gaze, Kabuto looked at his left hand, where a mysterious black rhombus mark suddenly appeared in his palm. Information about this mark also abruptly appeared in his mind.

"Wedge mark?"

How do I know the name of this mark?

Did this guy do this to me?

Kabuto instinctively reached for his glasses, only to find they were empty; he then realized he wasn't wearing them.

At the same time, he also noticed that his perspective was different from before.

Can the Sharingan and Byakugan be switched on and off freely now?

So, was my fusion ritual a success or a failure?

Or is it that I originally failed, but succeeded because of this person in front of me?

"who are you?"

Kabuto Yakushi raised his head again, his eyes suddenly turning crimson, and his Byakugan snapped open. He asked the same question to the man on the platform once more.

Ultimately, he was the most outstanding spy in the ninja world. At first, he seemed completely confused, but he quickly calmed down and remained vigilant.

After successfully creating another pair of Mangekyou Sharingan by fusing the power of multiple Sharingan eyes into the Mangekyou Sharingan.

Yesterday, Yakushi Kabuto performed a ceremony to fuse Oni-ra with the bloodline of the Sage of Six Paths.

He utilized the geographical advantage mentioned in the scroll of Biluhu—Mount Sumeru, and the human advantage—the Ghost Sprout Luo Technique Formation.

As for the timing, the next annular solar eclipse is still about a year away.

Yakushi Kabuto then devised other methods as alternatives.

With the calculated data correct and the experimental simulation successful, Pharmacist Kabuto began the ceremony.

At first, the fusion ritual went very smoothly. Kabuto Yakushi could clearly sense that as the ritual progressed, the chakra and power within his body were soaring at an incredible rate.

He even suspected that once the ritual was fully completed, his power would advance to a god-like level, recreating the mighty power of the Sage of Six Paths, the founder of the Ninja Sect.

But cruel reality soon shattered Kabuto's dream during the final step of the ritual.

In an instant, the chakra that had been rapidly merging into his body went berserk, began to collide wildly, and expanded rapidly.

The ritual seemed to lack something crucial, which inevitably led to his failure and his eventual death by exploding.

"You can call me Jigen, a monk who cares a little about the ninja world."

Ōtsutsuki Isshiki tapped the armrest lightly with his fingers and responded calmly.

“Monks? Ha….”

Kabuto Yakushi's lips twitched slightly. In his line of sight, a man named Jigen stared directly into his Sharingan with his dark, indifferent eyes, neither looking away nor yielding.

Black eyes are not uncommon in the ninja world, but this person's eyes were the kind that seemed to devour all light, turning into a deep, dark, bottomless darkness.

"You saved me? And what is the Wedge Mark? Why is that name appearing in my mind?"

"I saved you."

Otsutsuki Isshiki nodded and said, "The Karma seal is a unique ability of mine. It allows me to copy myself and digitize myself, and then implant this data into other people's bodies. A black diamond-shaped mark will appear on the palm of the person whose data is implanted, which is the one on your left palm now, as the initial mark. This mark is the Karma seal."

"Sounds a lot like a cursed seal, hehe."

Upon hearing this, Kabuto Yakushi's expression remained unchanged, but it was impossible to know what he was thinking.

“A cursed seal? You can think of it as a more advanced cursed seal. The data in the seal will gradually thaw over time. You can also accelerate the thawing of this data by continuously releasing the power of the seal during battle. When all the data is thawed, the person who was placed with the seal will be completely replaced by me.”

"So, you're saying my body has now become your vessel?"

I'm familiar with this situation.

Kabuto's eyes flickered as he recalled Orochimaru's scheme to possess Sasuke Uchiha's body.

Did this guy save me just so I could become his vessel?

Was it premeditated?

Or was it a spur-of-the-moment decision?

"Yes and no."

Otsutsuki Isshiki responded calmly.

"Those who have seen the light of the sun will look down on the glowing flame. Your current body is nothing but a counterfeit in my eyes, only suitable as a backup. I will not choose you as my vessel for reincarnation unless absolutely necessary."

Counterfeit and shoddy products!

A backup option!

Ōtsutsuki Isshiki spoke in a calm tone, but his calmness seemed to be telling a predetermined and cruel reality.

Even the usually resilient Kabuto Yakushi couldn't help but feel a surge of anger upon hearing this assessment.

He endured humiliation and hardship for two and a half years under Sasuke Uchiha, and the work he painstakingly planned and completed only received the evaluation of being a counterfeit.

However, Kabuto Yakushi is Kabuto Yakushi after all, and with his resilient mind, he quickly regained his composure.

"Then, Lord Jigen, who saved me, who is the perfect vessel for reincarnation in your heart? What do you need me to do?"

The pharmacist remained calm as he probed Cixian's intentions.

"You calmed down so quickly? I really overestimated you. Actually, you don't need to be angry. Your anger is irrelevant to me. I'm just stating a fact."

Ōtsutsuki Isshiki chuckled lightly: "Moreover, we share a common enemy and a common goal."

A common enemy and a common goal?

"You mean Uchiha Sasuke? You think Uchiha Sasuke is the perfect vessel?"

Upon hearing this, Kabuto lowered his eyes slightly, then raised them again a moment later, and said calmly, "If that's the case, please allow me to refuse."

"Sasuke Uchiha's body belongs to me, and I will not allow anyone to take it away."

To complete Orochimaru's unfinished business and seize Sasuke Uchiha's body.

Just like in his original timeline, this event became the belief that motivated him to live.

Moreover, because of the extra two and a half years of humiliation and hardship he endured in this timeline, his obsession with taking over Uchiha Sasuke's body was much deeper.

For Kabuto Yakushi right now, this matter is more important than anything else, even life and death.

"I'm sorry, you misunderstood, Kabuto Yakushi. I am not interested in Sasuke Uchiha's body."

Otsutsuki Isshiki said calmly, though this was only his outward appearance. In reality, Uchiha Sasuke was now qualified to feed the new God Tree and help it grow stronger.

However, there's no need to say these things to Kabuto; he's just a tool anyway.

"My target is a clone he just created."

"A newly created clone? You mean the ritual from a few days ago?"

"Yes, it was that ritual that allowed Uchiha Sasuke to create a new clone, a body that fits me perfectly."

Otsutsuki Isshiki nodded and continued, "Yakushi Kabuto, it seems that although you have served as Sasuke Uchiha's close assistant for two or three years, you do not really understand him, or rather, he still keeps many secrets from you."

"However, that makes sense. If he hadn't held anything back from you, you would have known that her direct descendants were not just five, but seven. What you lack are precisely the two lineages that act as the unifying agents."

Mixing agent?

Yes, a harmonizer!

Upon hearing this, Kabuto suddenly realized why his body had expanded rapidly at the end of the ritual, almost resulting in his body exploding and dying.

That's because the different energies he absorbed into his body did not fuse together.

Or rather, they merged, but at a very slow pace, far slower than the rate at which energy continued to flow in.

At this moment, Kabuto Yakushi also heard Jigen mention her.

It's her, not him!

The Sage of Six Paths is said to be male, although the possibility of him being female cannot be ruled out.

But Kabuto knew that the "she" Jigen was referring to was not the Sage of Six Paths, but another woman he didn't know.

Or rather, a goddess!

Could it be the goddess of the rabbit?

The Goddess of the Rabbit is the most well-known and widely circulated goddess in the ninja world. More importantly, like the Sage of Six Paths, she also holds the status of a creator god in mythology.

How could a descendant of the Sage of Six Paths be related to the Goddess of the Rabbit?

Kabuto Yakushi had never heard of any connection between the Sage of Six Paths and the Goddess of the Rabbit.

The goddess received blessings from all living beings and gave birth to a divine child.

Suddenly, Kabuto Yakushi recalled a conversation he overheard among the locals in a village on the border between the Land of Wind and the Land of Demons when he was a spy.

In that instant, he seemed to understand something.

"It is precisely because of the lack of a harmonizing agent that the energy and blood flowing into your body could not quickly integrate, which led to the failure of your ritual."

Can't they be blended without a blending agent?

of course not!

It's just that this speed will be very, very slow.

Just as Otsutsuki Isshiki knew, the previous Indra, Uchiha Madara, spent decades to finally complete the fusion without the necessary harmonizing agent.

It still has some flaws and is not a perfect Ten-Tails Divine Tree physique.

In the modern era, Indra covered in just two years what Madara Uchiha took decades to accomplish, and his physique was even more perfect.

Besides his own other plans, the Hamura clan bloodline, acting as a mediator, also played a crucial role.

Even with the existence of the harmonizing agent, fusing the bloodline of the Ten-Tails of the Divine Tree in a short period of time is an extremely dangerous thing.
