Konoha's Mission Master

"Thank you so much... Lord Yakumo!"

Fugaku Uchiha quickly stood up and made a gesture as if to bow.

Yakumo quickly stopped him.

Half an hour later, inside the Konoha Hospital laboratory.

Uchiha Itachi was asleep on the experimental table, next to a gene fusion fluid prepared by Yakumo's shadow clone. Yakumo, Tsunade, and Aoyama Reiko stood around him.

They wanted to witness firsthand the treatment of hemophilia.

This is the first case of a bloodline disease being cured in the entire ninja world. If Yakumo succeeds, he will represent the pinnacle of medical technology in the ninja world for a thousand years.

This is a miracle worthy of being included in medical textbooks.

During the medical exam at that time, when... Bai Bayun.

Tsunade's eyes could no longer conceal her eagerness...

In her view, the skills that Yakumo possessed were equivalent to the skills she possessed.

Can the bond between master and disciple really withstand such a simple test?

At this moment, Tsunade subconsciously ignored the initial incident of being stood up when they first met, and the merciless evaluation of her as a weakling when they first met in the Fire City.

"Well then... I'll begin."

Reiko Aoyama and Tsunade immediately began to concentrate on their study. They saw that Yakumo did not perform any hand seals, but his hands emitted a blue light that completely enveloped Itachi Uchiha's body.

Two drops of blood were placed in the petri dish.

Firstly, it comes from the patient, Uchiha Itachi.

Secondly, it comes from his father, Uchiha Fugaku.

Yakumo plans to use Fugaku Uchiha's blood to complete Itachi Uchiha's genes.

Before that... he needed to discover the genetic defects in Itachi Uchiha through comparison.

Under the influence of the azure light, Yakumo's vision slowly unfolded at an extremely microscopic angle.

Those were two staircases with mixed colors.

These are the genes of Itachi Uchiha and Fugaku Uchiha.

It is well known that normal human genes have a double helix structure, but while the Uchiha clan's genes also have a double helix structure, they are mixed with other colors and fragments...

These other fragments represent the incomplete Otsutsuki bloodline.

From this extremely microscopic perspective, Yakumo could use his eyes to determine the invasion of human genes by the Otsutsuki bloodline; this occupation was not fusion but malicious plunder…

Is power gained at the cost of lifespan?

Yakumo understood. After all, long-lived ninjas were rare in the ninja world, and there were only a handful known to exist. The Uzumaki clan seemed to have a long lifespan, which meant that the fragments they fused with were more stable.

This stability... eventually gave rise to a special secret technique that could suppress chakra: the Whirlpool Sealing Technique.

Another manifestation of this stability is longevity.

However, not everyone in the Uzumaki clan has the constitution for longevity; for the majority, lifespan is still difficult to extend.

Yakumo regained his composure and focused more on comparing the two staircases, beginning to search for the missing parts of Itachi Uchiha.

Time passed slowly...

Although Tsunade and Reiko Aoyama were also observing carefully, neither of them could understand Yakumo's actions at all.

In short, I couldn't understand it, but I was deeply shocked.

The hot-tempered Tsunade has left the laboratory, while Reiko Aoyama continues to observe patiently.

Yakumo had performed cell activation on her, so she was even more aware of Yakumo's mastery of the Palm Healing Technique.

That is... moving between cells without compromising its delicate texture, like the silent, refreshing coolness of a clear spring.

Reiko Aoyama couldn't help but recall the process of cell activation.

On the other hand, Yakumo finally found the crucial fragment. Compared to Fugaku Uchiha, Itachi Uchiha was indeed missing a very small portion of the fragment.

This also led to a depletion of his innate vital energy.

Yakumo manipulated tiny golden currents to cut the two fragments, even though in his eyes the two genes looked like huge steps.

In reality, however, these two segments are extremely small.

The first attempt failed due to the disordered golden current.

The second time, the golden current was too strong, and the cells were destroyed.

The third attempt failed because the golden current was too weak.

The fourth attempt... failed.

"Damn it... I shouldn't have failed."

"How could there be a problem with the first step?"

Yakumo sat on the ground and began to recover his strength.

At the same time, he closed his eyes and gave instructions to Aoyama Reiko.

"If Itachi wakes up, cut his nerves again."

"clear."

Reiko Aoyama nodded immediately, her face serious as if she were an extremely experienced and qualified assistant. On the experimental table, Itachi Uchiha was snoring softly.

Half an hour later, Yakumo stood up.

The fifth cut... begins.

Although both Itachi Uchiha and Masako Mori suffer from bloodline diseases, their treatment approaches differ greatly. The former requires the completion of gene fragments, while the latter involves the fusion of conflicting gene fragments.

Yakumo quickly found the gene…

Fifth cut successful!

In fact, Yakumo has carried out this kind of cutting work many times in the Free Federation... that is, the real copy.

Yakumo believed that the previous failures were not due to a lack of skill, but simply because the tools in the ninja world were not as sophisticated as those in the Free Federation world.

Yakumo breathed a sigh of relief, immersed the gene in the gene fusion fluid, and slowly used the azure energy cluster born from the life mastery to promote the fusion of the two genes.

This is a meticulous process that allows no room for error, but fortunately everything is moving in a positive direction.

As time went on, the two gene fragments in the petri dish slowly began to fuse, like two soap bubbles slowly gathering together.

If things continue like this, there are only two possibilities: either they will repel each other and eventually break apart, or they will successfully merge and completely cure Itachi Uchiha.

PS: Please vote for me! I'll correct any typos later.

Chapter 259 Mastery, New Pieces

Konoha Hospital, Research Lab.

Yakumo stared intently at the petri dish in front of him. The gene fusion fluid was the breeding ground for the fusion of two gene fragments, and the energy derived from life control was the guide for the gene fragments.

That gene fragment from Fugaku Uchiha was almost identical to Itachi Uchiha's own genes.

The two similar colored staircases slowly approached each other, a sign of gene fusion, and everything was gradually developing in a positive direction.

Half an hour later, the two gene fragments had fused. The next step was to determine whether there would be a rejection reaction between them through proliferation and division.

Under the influence of the blue light, the cell carrying the new genes began to divide, and Yakumo gradually increased the energy output until the cell tissue filled the entire culture dish.

Yakumo created a shadow clone to conduct an inspection.

After the two genes were fused, no rejection reaction occurred.

This is an absolutely crucial step... victory is within reach!

Yakumo rubbed her aching temples, handed over the cell culture work to Aoyama Reiko, and sat on the ground with her eyes closed to recover her depleted energy.

At noon, Yakumo collected the cultured cell tissue mixed with gene fusion solution into a syringe about the thickness of a forearm; the slender silver needle reflected a metallic luster.

Reiko Aoyama took the syringe and inserted the syringe, which was filled with healthy cell tissue, into Itachi Uchiha's right arm.

Yakumo then began to fully activate the Life Mastery skill, and the azure light completely enveloped Itachi Uchiha's body on the test platform.

Under the influence of the azure light cluster and the gene fusion fluid, the new cell tissue did not cause any rejection reaction, and under the control of life's mastery of this skill, it gradually spread and merged with the surrounding damaged cells.

Itachi Uchiha's body instinctively began to automatically complete the task.

Two hours later, Aoyama Reiko had injected all the cells into the syringe, and Yakumo was still maintaining his life control skills, with sweat gradually dripping down his cheeks.

Without the aid of sophisticated instruments, the energy consumed by gene fusion becomes somewhat terrifying, or perhaps it's because the genes of the Otsutsuki are inherently special... leading to excessive energy consumption.

At 2 PM, Yakumo carried Itachi Uchiha out of the laboratory and handed him to Fugaku Uchiha. Seeing that Itachi was safe and sound, the worry on his face gradually disappeared.

"Mikoto...didn't my sister come?"

Yakumo asked, somewhat puzzled.

"I didn't tell her because I was afraid she would worry."

Fugaku Uchiha answered in a deep voice, an inevitable happy smile appearing on his face when he thought of his wife.

"I see. Little Weasel may have a sudden increase in appetite these days. This is a normal reaction after recovery, and it is expected to fully recover within a few days."

Yakumo patiently gave his instructions.

This treatment filled the gaps in Itachi Uchiha's genes, and even gave him the foundation to directly reach the Eternal Mangekyou Sharingan.

Building such a foundation requires a huge amount of nutrients.

"Okay, okay... I understand."

Fugaku Uchiha nodded in agreement.

After exchanging a few more pleasantries, Fugaku Uchiha announced his departure. He needed to go home to share the good news with Mikoto Uchiha, and he also had unfinished work to do in the Konoha Police Department.

Yakumo filled two cups with hot water from the water dispenser, then turned and went back to the lab. At that moment, Aoyama Reiko was packing up the experimental tools. She had only been helping out the whole time, but she was also exhausted and covered in sweat.

"So...did you understand?"

Yakumo handed a water glass to Aoyama Reiko as a greeting. The latter put down her work, took the ceramic glass, and gently blew on it a few times. White smoke spread towards the ceiling, blurring her beautiful face.
