Eye Technique: Yamata

[Eye Technique: Yamata activated successfully, host has acquired Shikotsumyaku (10% development)]

"Does the development of bloodlines decay after successful plundering..."

Although the Shikotsumyaku development obtained by Shisui through Yamata was halved compared to Takedake Oyama's 20% Shikotsumyaku development, such a heaven-defying skill, even with some drawbacks, was within an acceptable range.

Fortunately, the use of Eye Technique: Yamata this time did not consume much of Shisui's Mangekyō Sharingan power in his right eye, only equivalent to the consumption of activating the initial form of Susanoo, which was within Shisui's acceptable range.

After acquiring "Shikotsumyaku," Shisui's status panel in the system updated again.

"With my level of Shikotsumyaku, I can only control the position of the bones within my body and slightly enhance the strength of some bones. I can't even perform the simplest bone extrusion."

Shisui tried for a long time in place and found that with only 10% development, the greatest effect of "Shikotsumyaku" was the difference between "having" and "not having," and it did not provide any increase in strength for Shisui at this stage.

"Unless I can plunder more Shikotsumyaku from the Takedake clan..."

Although he had an idea, this was not the best time for Shisui to cause trouble in Kirigakure; he still had his original purpose for coming.

Uchiha Madara had already made arrangements for this.

As Shisui approached the Mizukage's office building, a masked Kirigakure Anbu appeared before him and said, "The Mizukage has been waiting for a long time. Please follow me."

Unlike the mask styles of Konoha, the masks of Kirigakure's Anbu appeared extremely ugly to Shisui.

The white mask had the Kirigakure symbol carved on its forehead, the eye area was a thin, long line, and the ugliest mouth area was a pieced-together black part. Shisui could only try his best not to let his gaze fall on the other party's mask.

"When I see Uchiha Madara later, I'll definitely have him change the mask style for Kirigakure's Anbu," Shisui grumbled inwardly.

"The Mizukage's office is ahead. Please proceed alone, Your Excellency." The Kirigakure Anbu leading the way stopped and gestured for Shisui to go ahead by himself.

It was clear that Uchiha Madara did not want anyone else involved in his meeting with Shisui.

When Shisui entered the Mizukage's office, he indeed saw only an old man with white hair and a child-faced man with green hair, purple eyes, and a scar resembling stitches under his left eye.

If nothing unexpected happened, these two were the masterminds behind everything: Uchiha Madara and the Fourth Mizukage Karatachi Yagura, who was controlled by genjutsu.

[Detected successful meeting between host and Uchiha Madara, reward: Fire Release proficiency +50%]

[Congratulations to the host for successfully advancing Fire Release proficiency]

[Name: Uchiha Shisui]

[Age: 8]

[Bloodline: Indra Bloodline (65% development) - Mangekyō Sharingan (Susanoo Third Form), Shikotsumyaku (10% development)]

[Detected that the host's Fire Release has reached mastery, host can now fuse Fire Release ninjutsu with ninjutsu of other attributes]

The system's prompt reminded Shisui of the Third Hokage, Hiruzen Sarutobi, known as the "Ninjutsu Professor." He could create more powerful composite ninjutsu by layering ninjutsu of different attributes, likely because Hiruzen Sarutobi's proficiency in all five chakra natures had reached mastery.

"Are you Uchiha Madara?" Although Shisui had heard many legends about Uchiha Madara within the clan, upon seeing this strongest figure in Uchiha history for the first time, Shisui didn't feel anything particularly special about him.

"I believe you've already guessed, haven't you?" Old Madara showed no emotional fluctuation due to Shisui's rudeness; he was also observing this outstanding junior.

"I'm very curious, how did Lord Madara control the Fourth Mizukage?" Shisui asked the reason, though he had already roughly guessed the outcome in his heart.

"I secretly helped Karatachi Yagura become the jinchūriki of the Three-Tails, Isobu, and then used my Mangekyō Sharingan's power to control Yagura. That's all." As he spoke, Uchiha Madara displayed his Mangekyō Sharingan.

"It seems that after I changed the fate of Obito and Rin, Karatachi Yagura directly became Isobu's first jinchūriki," Shisui thought to himself.

At the same time, Shisui noticed that the pattern of the Mangekyō Sharingan in the other party's eyes seemed different from the one used in the Fourth Great Ninja War.

"Why does the spiritual power I sense from these eyes conflict with your own?" Shisui asked tentatively.

"Sharp insight."

Uchiha Madara's gaze fixed on Shisui's right eye and he continued, "For some reason, the original owner of these eyes is not me. If you agree to join my plan now, these eyes can be a gift to you."

"Why do you only have one Mangekyō Sharingan?" Even Uchiha Madara, who had lived for nearly a hundred years, had never seen a case of awakening only one eye.

"My left eye's power was overused in a battle." Shisui had no intention of revealing his true situation to Uchiha Madara, but he also provided a seemingly reasonable explanation.

Old Madara stared directly at Shisui, as if trying to see through the truth of his words, but after a moment, Madara stopped dwelling on the issue. Although everyone had their secrets, Madara was confident enough to control the overall direction of events.

"Join my plan, and I can also help you solve the problem with your left eye." Madara's tone was full of temptation, believing that Shisui, who had just tasted the power, could not refuse this offer.

"Alright, I agree. However, if I encounter a situation that threatens my life during the execution of the plan, I will immediately give up and withdraw." In front of an old fox like Uchiha Madara, any small tricks seemed redundant. Shisui directly stated his bottom line to maximize his own interests.
