Konoha's Mission Master

Chapter 451 Arena, Tenth Floor.

Black sand billows in the empty Starry Sky Arena.

The battlefield between the two was a completely dead planet. Yakumo could not sense any life within his soul's range, and there was no oxygen in the air that life depended on.

Only the constantly blowing iron filings cut into my skin like tiny knives.

The environment here is even harsher. Although there is no oxygen, the air is filled with colorless and odorless neurotoxins that penetrate the body through the skin.

The space was completely still. Buu was like a pink sphere fixed in a canvas, while Yakumo had the ability to move at any time, but could not leave the three-meter radius around him.

Over the past two years, from Yakumo's initial probing of the system to directly confronting the true master of the game system, he has been under immense pressure.

Under this pressure... he created thousands of shadow clones... solely to develop a powerful sword technique suited to him, no longer relying on the system's assistance.

Unfortunately, more than ten days passed without any results.

The Origin Blade Technique was more profound than he had imagined. When he tried to change any of the three variables, it caused the entire technique to collapse, become unbalanced, and then lose much of its power.

Energy, soul, and will cannot be altered.

But it's not a big problem. Yakumo plans to deal with Buu first, and he also has a concrete and feasible plan for improving the moves, which is to increase the proportion of the three by two times.

"three."

"two."

"one."

A bright red countdown appeared in the void, and the surrounding environment seemed to be gradually awakening, becoming even more hostile... Terrifying metallic dust formed a black tornado.

The sky was also covered by thick gray smog, obscuring the sunlight.

The temperature is very low, around minus seventy degrees Celsius.

The environment is dry, with no frost or snow.

If Yasuo, the Unforgiven, is a lone hero who fights to the bitter end, then Buu is the source of destruction and annihilation, emanating pure white steam as his pink sphere gradually wriggles, growing limbs and a head.

Kid Buu is only a meter tall, yet he possesses terrifying resilience, almost immortal. He was once split in two by Yakumo, but he instantly healed. Yakumo speculates that his soul is not a whole body, but rather resides within the cells, which is why he possesses terrifying immortality and powerful control over his body.

However, things are different today.

The Origin Blade Technique is not a single, fixed move, but a special state that transcends Extreme Blade Slash, Soul Slash, and Star Slash.

It allows the three energies within Yakumo's body to perfectly fuse, unleashing power nearly ten times the limit. In other words... once the three energies are fully fused, each strike is equivalent to a star-slaying attack.

Yakumo began preparations the instant the countdown reached zero.

"Sage Art: Wood Release: Blood Soul Armor".

The blood vines formed armor covering his entire body. Yakumo knew that although the surrounding poison gas could not have a significant impact on him, it would still weaken his body. Therefore, isolating the toxins from his skin was an important step.

In addition, Buu is completely immune to these toxins and can even absorb them to restore the physical strength lost in battle.

That's absolutely insane.

The Blood Soul Armor created a defense that isolated Yakumo from the poison gas. Then, he gripped the Demon-Subduing Sword he had drawn from behind his back and spoke softly.

"Sage Mode, activated!"

"Mark of Prayer, open!"

At the same time, Yakumo suppressed all his energy inside his body, ensuring that there was no leakage. Buu could absorb all forms of energy through contact, including physical strength.

Once, Yakumo tried to use the effects of holy light to temper Buu and burn him with the fire of the sun, but the result surprised him greatly. Although the pure white flames caused Buu damage and excruciating pain.

However, the final result was that Buu adapted to and absorbed the Sunfire, which indirectly increased Buu's strength.

Before Yakumo could even make a move, Buu had already arrived in front of him in an instant, leaving behind a trail of white steam in his path. This was Buu's special ability: to release steam through the holes in his body to increase his movement speed.

This kind of improvement is an instantaneous burst, and it can only move in a straight line from beginning to end. It cannot change direction flexibly. It is precisely because it abandons the characteristics of flexible movement that its speed can be comparable to Yakumo's spatial movement.

The two continued to move and clash, and the transparent air waves mixed with white steam exploded like air bombs. Yakumo and Buu instantly moved at the center of the explosion.

No trace of them could be found in the space, as if they had vanished into thin air, but the aftershocks of their battle continued to spread, with countless white fireworks exploding.

Kid Buu's body was hit at the speed of a cannonball. In mid-air, he transformed into a pink sphere to mitigate the impact, but still smashed through a distant mountain peak, splashing up countless black sand particles.

At the same time, countless stones flew everywhere.

Buu stood up from the pile of rubble, his body swelling like a balloon after the impact. He absorbed the surrounding poison gas, and the knife wounds on his body healed at an extremely fast speed without any bleeding.

It seems to have no blood in its body, and its body structure is quite magical. It can not only create steam out of thin air, but also extend and contract its body length at will.

This feeling is like an enhanced version of Luffy, except that his vitality is many times more terrifying... and he also has the ability to absorb energy.

The two faced off. Although Buu seemed crazy and irrational, he actually possessed extremely high intelligence and naturally understood how to seek advantages and avoid disadvantages. The so-called standoff was more like a discussion on how to deal with the enemy.

Yakumo teleported instantly, his blade flashing with blue and golden light. Within his body, his soul energy served as a medium, drawing in various energies to fuse and reshape, ultimately guided by his will.

"Source Blade Technique - Star Slash Stage".

The fused energy burned rapidly, achieving extreme speed. Yakumo suddenly felt that Buu in front of him was not insurmountable. His entire body seemed to transform into a golden pathway, and the flow of the entire world slowed down.

When Yakumo used the Star-Slaying Stage for the first time in its entirety, he finally gained a direct understanding of the power of Uchiha Juntama, who created the ultimate sword technique. Even though he had only learned the disassembled version, he still experienced a terrifying improvement.

"Unfortunately... this state can only be maintained for thirty seconds."

Yakumo analyzed his own condition and realized that the fusion of the three systems in the Star-Slaying state was putting a lot of pressure on his body, especially his weak point, Willpower, which was losing power even faster.

It will be completely exhausted in about thirty seconds.

Swish.

Yakumo held the Demon-Subduing Sword in front of him, which surged forward like a golden meteor.

Buu, of course, couldn't just sit idly by and wait to die. A large amount of steam spread from his body, and his speed suddenly reached a new peak. As he moved, the steam formed pure white triangular cones, like a high-speed train.

Beneath his pink skin, raised vein-like marks resembled countless worms wriggling and moving, looking exceptionally ferocious. Clearly, Buu sensed the pressure... and had also used his trump card.

Steam billowed like a tornado, and the gale-force winds whistled through the holes in Buu's body, producing a sharp and mournful sound, like the savage laughter of a demon from hell.

Yakumo swung his sword and kept slashing at Buu, but he did not die instantly. Even with the enhancement of his Star-Slaying state, Fuma could not completely sever Buu's muscle tissue.

However, the new energy fused from the Star-Slaying state can prevent Buu's body from healing, and even with its special constitution, it cannot quickly absorb this golden energy.

On the other hand, Buu is also launching a frantic counterattack, as if he has reached the end of his rope, and he may have already sensed the approach of death.

The more Yakumo used it, the more he could feel the power of the Star-Slaying State. That energy could be attached to the blade and strengthened the body. It possessed both the unpredictable and mysterious nature of soul energy and an indescribable domineering power.

"call..."

As the gray fog rose, Buu created a massive amount of white mist that enveloped Yakumo. This dense fog seemed to be alive, following the two of them closely. Yakumo gradually realized that his senses seemed to be malfunctioning.

Buu's presence seemed to emanate from all directions, yet his intuition told him that Buu was right before him...

Yakumo's perception was partially obscured by the fog created by Buu around him, which was infused with Buu's own cells.

This is a skill that Buu has never used before. It was obviously a random method he came up with to counter Yakumo's Star-Slaying state. He intended to use this method to obscure the lock of will and the slash of the blade.

Yakumo had to admit that Buu's tactics were quite good; they could indeed interfere with Yakumo's judgment when wielding his weapon, just like an enemy suddenly splitting into several complete individuals, making it impossible to accurately guide the direction.

Will, soul, and eyes offer three answers.

Furthermore, Yakumo discovered that Buu's movement speed in the fog had once again increased significantly, but unfortunately... it couldn't completely tip the scales of victory.

Yakumo took a moment to form hand seals and create a shadow clone. It was a simple action, but it almost caused him to lose his Star-Slaying state. This special state requires absolute focus and cannot be distracted in any way.

The shadow clones clasped their hands together.

"Eternal Sleep Mist".

Yakumo used this trump card skill again. For some reason, he felt that the eternal slumber mist around him was closer to him, and its color had become darker, a leaden gray, which made him feel even more desperate.

The moment the two types of mist came into contact, the mist created by Buu began to crumble. In its haste to find a way to restrain Yakumo, it was ultimately no match for the Eternal Sleep Mist, which had undergone several evolutions.

Lead-gray mist enveloped Yakumo and Buu, and a strong wind whipped through everything around them... Buu screamed repeatedly as the cells mixed in with the mist were being devoured, a feeling that terrified him.

The golden light on Yakumo's blade was already fading, and the duration of the Star-Slaying state was nearing its end, but the outcome was already decided.

Buu's body is being destroyed by the fused energy, an energy that he cannot assimilate, digest, or absorb. This near-immortal creature is finally facing his end.

Yakumo continued his offensive, forming a golden disc about three meters in diameter around his hand as he unleashed his Fuma technique. Since the Origin Blade Technique was a state, he could naturally use his sword techniques while in this state.

The golden millstone, like a sharp chainsaw, continuously and rapidly cut through Buu's body, while the splattered cells were absorbed by the eternal slumber mist.

It turns out that all that is needed is to completely destroy the unity of Buu's body, so that it can be completely eradicated like a skilled butcher dissecting an ox, crushing all its cells and tissues, and rendering them unable to regenerate or function.

Buu struggled and screamed... attempting to fight back.

"Star-Slaying State, extinguished."

Yakumo felt a wave of weakness wash over her, but thankfully Buu had already lost the ability to resist. Although the pink flesh was still slowly struggling, the outcome was already sealed.

The golden blade energy continued to wreak havoc, like a blender.

In the blink of an eye, half an hour had passed.

Yakumo deactivated the golden millstone and the heavy, eternal slumbering mist. Although he was exhausted, he had ultimately defeated his enemy, and his Soul Eye could no longer sense Buu's presence.

Congratulations, player, you have successfully completed the challenge.

Five bright red characters appeared in the void, the surrounding planets slowly disintegrated, and countless massive mountains flew towards the wounds, gradually turning into clods of earth and stones, but in the end they were all turned into dust.

Yakumo gazed at the still-lingering black tornado in the distance, removed his somewhat tattered Blood Soul Armor, and floated silently in mid-air... his eyes watching the entire world sink and vanish.

The scene before me possesses an extremely magnificent beauty.

Yakumo saw with his own eyes... that there were actually green plants and slowly moving hamsters deep underground. The so-called deathly silence was just that he had overlooked the deeply hidden vitality.

"It turns out that this world is not completely dead."

He murmured a sigh, watching as those fragile lives were replaced by an invisible force and transformed into pure white light and electricity. Countless white lights and electricity, like bright fireflies, stretched continuously into the sky.

This scene was like a moving miracle.

Yakumo began to refine his swordsmanship. In battle, most of his energy was used to maintain the Zankai state, which meant that the techniques he could unleash could not incorporate energy and soul.

"Rebellion, waltz, layering of energy."

These are the three techniques that Yakumo can use normally. As for the other techniques, they all involve the flow of energy. For example, Wei Guo uses an instantaneous burst of extreme energy, such as... the energy compressed to the extreme during Shunko. Similarly, the Extreme Blade Slash is essentially just the energy compressed to the extreme.

Yakumo discovers that his future path may involve abandoning energy-based techniques and researching personal swordsmanship skills, which must be based on physical strength and not involve willpower.

This is one direction, but we need to make some trade-offs.

The world was nearing its end, and Yakumo saw the scorching, pulsating Earth's core transformed into white points of light, and witnessed the final stone being completely transformed.
