Konoha's Mission Master

"Fusion."

Yakumo stretched out his right hand and touched the enormous, blood-red heart.

The next second, a bright red chain pierced Yakumo's chest and connected to his heart, and gushing blood-red energy slowly flowed into his heart.

Most of this energy is stored in the heart, gradually subsiding as if entering a dormant state. Only when Yakumo uses Berserk Blood or Immortality will this energy be activated, unleashing its ferocious nature.

A small portion of the energy flowed into his body to strengthen him. The original crimson immortal mark dissipated, and his muscles and bones were being destroyed and rebuilt. Blood beads were squeezed out of his body and dispersed in a misty haze.

After a long while, Yakumo opened his eyes, his gaze silent.

With a wave of the hand, the personal interface unfolds.

Constitution: 61.0 (Endurance, Resistance, Recovery)

Since most of the energy was stored in his heart, the remaining small amount of energy only brought a 1-point increase in his physical attributes, which disappointed him somewhat.

While Berserk and Undying are strong, the improvement in these attributes does not quite match Mundo's level.

Yakumo carefully felt his heartbeat become stronger.

With a wave of his hand, golden arcs of electricity danced at his fingertips, and Yakumo's ability to control lightning-type abilities became much stronger.

His lightning power is now comparable to Enel's in the first tier of the arena.

Unfortunately, the only drawback is that Yakumo cannot be elementalized.

The wide staircase converged from the sky and finally stopped in front of Yakumo, emitting a soft white light.

The stairs were extremely long; even when Yakumo looked up, he couldn't see the end. For some reason, he felt a vague sense of familiarity when he saw the stairs.

It seems that many years ago, he also climbed this staircase that leads straight to the sky... until... until what?

A look of confusion appeared in Yakumo's eyes.

Unconsciously, my feet stepped onto the stairs, and light and shadow flowed before my eyes. The originally dark dome of the arena was now filled with countless twinkling stars.

The arena has expanded significantly, becoming much larger and allowing for more exhilarating battles.

Each stage consists of six floors, and the person in front of you is the boss guarding the stage!

In the center of the arena sat an old man clad in golden armor and wearing an eagle helmet. His silver hair moved without wind, and his bright red cloak fluttered in the wind.

When he looked up, Yakumo felt as if he were locked in by death.

The next second, the person instantly appeared in front of Yakumo. There was no process or path; he appeared out of thin air with unparalleled pressure!

The old man thrust out the spear in his right hand, and Yakumo immediately blocked Fuma in front of him, the spear clashing with Fuma like a spear made of tree branches.

An unparalleled force surged forth, rushing into his arms.

This force came on fiercely and at extremely fast speed, and Yakumo didn't have time to activate his stacking energy technique.

A series of cracking sounds emanated from Yakumo's arms, and blood mixed with golden arcs of electricity splattered outwards without restraint. In the blink of an eye, the bones in his arms broke into three sections, the pale cuts piercing his skin.

With a crack, the demon-subduing object shattered.

Silver fragments flew everywhere.

The silver-haired old man, wielding a long spear, thrust it effortlessly into Yakumo's chest, piercing his heart and exiting through his body with the spear tip protruding.

The violent force flipped Yakumo over and pinned him to the ground, a dense aura of death spreading from his wounds.

Yakumo's flesh and blood gradually turned grayish-white.

"Undying, Berserk Blood!"

Yakumo's face darkened, and he immediately used the ability he had just acquired. Although this could not change the outcome, it could at least change his fate of being instantly killed.

The silver-haired old man merely snorted coldly, and a golden domain expanded outward from his body, the golden waves sweeping over Yakumo's body.

Although Undying and Bloodlust were successfully activated, they were firmly suppressed by the Golden Domain, allowing them to unleash less than 30% of their power.

The silver-haired old man swung his spear, and an aura of death swept over him. More flesh and blood turned grayish-white. He was now like a sacrifice nailed to an altar, his blood swallowed up by the aura of death before it could even flow.

Yakumo's vision went black, and blood-red words appeared in the void.

"Challenge failed."

"That's ruthless."

All of Yakumo's wounds have healed.

However, his face was very pale. He had imagined that the sixth level of the arena would be difficult, but he did not expect it to be this difficult.

If Yakumo's guess is correct, that person should be Odin!

Odin, the supreme god of the Norse Aesir, is regarded as the king of the gods, as well as the god of the sky, death, war, power, and magic.

That unremarkable spear must be the legendary weapon, Gungnir, forged from the branches of the World Tree.

The divine weapon, which was originally infallible, was imbued with the power of death in the arena, gaining a curse that meant certain death upon being pierced.

When Gungnir pierced his body, all of Yakumo's regenerative abilities were rendered ineffective by the suppression of the death aura, his cell activity was greatly suppressed, and even the effect of his life control was weakened as much as possible.

"Damn it."

"Leave the arena."

Yakumo emerged from the wardrobe.

Despite suffering a great setback in the arena, his spirit remained high, especially as his heart continuously channeled crimson energy to his limbs and bones, like the ebb and flow of tides, constantly strengthening Yakumo's physique.

This feeling completely swept away the physical fatigue.

Will the Undying Heart slowly increase physical strength?

Yakumo landed in the courtyard, slowly swinging his sword, seeking boundless tranquility in his heart. After completing the Nine-Slash Stacked Force practice, Yakumo planned to continue studying the stacked force method, transforming the original passive rebound into an active accumulation of power.

This method of power generation is very common in novels. It generally involves accumulating muscle strength to achieve a sudden burst of power.

This kind of layering of energy is more like... accumulating power.

The three-foot sword technique is the sword skill that gathers power in the scabbard.

Yakumo has already made a start; all he needs to do is experiment.

"Huff, huff, huff."

A few hours later, as dawn broke... sheathed her sword.

A brand new day.

In the morning, Yakumo went to Konoha Hospital to practice life control, which mainly involved constantly altering the genes of insects.

Kill all the insects used in the experiment before leaving get off work.

At night, they first went to the Konoha Cemetery to accompany Yukotsu Chiyuki in practicing her swordsmanship.

Back home, I would either spar with Masako Mori or have a simple chat.

And so... two months passed.

In mid-August of the 45th year of Konoha.

At this point, the mastery of life had reached the Grandmaster level.

Unfortunately, breaking through to the Dao Transformation level requires 68 points of physical constitution.

Yakumo was far from reaching that level, so he decided to stop hesitating and prepare to heal Mori Masako directly.

By the way.

In two months, Yakumo's physical condition improved by 0.2.

Constitution: 61.2 (Endurance, Resistance, Recovery)

Beneath the original bedroom, Yakumo manipulated the land and excavated a laboratory of over 100 square meters within two months.

At the same time, through Shinichi's connections, Yakumo obtained many top-notch experimental equipment in the ninja world, forming a top-notch laboratory comparable to Konoha Hospital.

This is done simply to increase the success rate of the treatment.

The laboratory was decorated by Yakumo in a very cozy style. Apart from a few huge, cold and hard experimental instruments, it was decorated as much as possible in pink, making it more like a princess's bedroom.

This was done to reduce Mori Masako's anxiety.

"Ahem, actually, I don't really like pink."

Masako Mori lay on the soft bed, her face slightly flushed.

This place doesn't resemble a treatment laboratory at all; it's more like a secret base for some kind of growth.

Under the pink lights, the air was filled with an ambiguous atmosphere.

"is it?"

Without looking up, Yakumo casually asked a question, his attention now focused on the upcoming treatment.

With a snap, Yakumo fastened the breathing mask to Mori Masako's cheek.

At the same time, the life support device is connected to the vein.

The final layer of insurance consists of life cells that have undergone multiple purification processes, which can serve as a safeguard should Mori Masako's life be in danger.

From treating Whitebeard to researching the One Piece world, from the ladder of gene warriors in the Free Federation to the recent treatment of Itachi Uchiha, these constitute Yakumo's experience in gene therapy.

Over the course of two months, Yakumo conducted hundreds of simulation experiments and also extracted Masako Mori's cells for more than a dozen fusion experiments.

Those three antagonistic genes did indeed fuse.

Yakumo creates shadow clones... to serve as his assistants.

In treating Masako Mori, Yakumo intends to do everything himself, from setting up the laboratory to officially starting treatment; he doesn't want anyone's help.

At the same time, Milk Ball was on guard inside the bedroom.

Around the underground laboratory, Yakumo constructed a perfect six-layer barrier with Yin-Yang sealing as the core for safety, while the safety outside the barrier was the responsibility of Mori Keiji, who had the strength of a Kage.

"Don't be nervous... I'm about to begin."

"Um... you're the one who's more nervous, aren't you?"

Masako Mori smiled as she looked at the sweat on Yakumo's cheeks.

"I'm not kidding, it's really about to begin."

"bring it on."
