From the night of genocide, marching towards the strongest.

His Rinnegan has the ability to contain all kinds of alien energy, as long as it's not too fast or exceeds the limit.

The Rinnegan's power is enough to ensure that his body will not undergo any mutations.

However, he has only recovered a little over half of his body so far. It would probably take three or four days for him to fully recover at this rate.

What exactly is the energy of the Grell Stone?

After Konan left, Nagato looked at the enormous blue gem in the sky, the size of a skyscraper, and his eyes flashed with deep doubt.

Nagato, who had never practiced immortal arts, naturally couldn't discern the energy of the Grell Stone.

If Sasuke were here, he would immediately recognize that the energy that constitutes the Grell Stone is natural energy.

Moreover, it is a special kind of natural energy!

Like the Dragon Vein, the Grell Stone is a product built upon the earth. For some unknown reason, it underwent a transformation, changing from the power of the earth's veins into a special kind of natural energy.

The natural energy of the dragon vein is special because it possesses the power of time and space, while Grell's natural energy is special because it has a powerful healing effect.

It's quite normal for absorbing too much Grell Stone to cause mutations.

Just as failing to master the sage arts at Mount Myōboku can lead to petrification, failing to master the sage arts at Ryūchi Cave can turn a person into blood.

Like the Cursed Immortal Body, absorbing too much of the Grell Stone can cause physical mutations and make a person extremely irritable with a strong tendency to destroy!

The people of the Grell Empire once suffered a tragic destruction because they overused the power of the Grell Stone, which ultimately led to their demise.

Chapter 287 Your use of the firewood escape technique was quite good.

The entrance to the Grell ruins.

The Akatsuki members were discussing tactics, and those present included Kazuma, Obito Uchiha, Zetsu, Pain, and the motionless Seven Swordsmen of the Mist.

"First of all, Uchiha Sasuke is very strong and has mastered the art of flight, making him extremely mobile. I don't think I need to elaborate on these points, as everyone should have a deep understanding of them."

Kazuma was considered a newcomer, Obito Uchiha pretended to be crazy and acted like a newcomer, and Nagato wanted to maintain his aloof and mysterious demeanor.

Therefore, the spokesperson for formulating tactics fell to Zetsu. Seeing that everyone was silent, Zetsu spoke again: "So let's talk about his Sharingan. Uchiha Sasuke now has the Eternal Mangekyou Sharingan, and his eye power is far stronger than that of his brother Uchiha Itachi."

"Based on the previous battle in the Land of Swamp, we know that Sasuke Uchiha's two eye techniques are the ability to manipulate flames and fuse them into an inextinguishable black flame similar to Itachi's Amaterasu, and the ability to manipulate lightning and fuse it into a kind of purple lightning with a built-in genjutsu and a slowing effect!"

"Therefore, we should try not to use Lightning Release and Fire Release to deal with him. Although it is not entirely useless, it is likely to be a waste of effort."

"As for the effects of these two eye techniques, I think I have explained them very clearly. I hope that everyone will try not to get touched by the black flames or look directly at the purple lightning during the battle."

Upon hearing this, Kazuma and Pain remained silent, but they didn't seem to care much.

Kazuma didn't need to fight in his physical body; he simply controlled the Edo Tensei army from behind. Neither Sasuke's inextinguishable black flames nor his genjutsu-infused purple lightning had any real effect on the immortal Edo Tensei.

As for Nagato, he could absorb the Black Flame's Preta Path, deflect the Deva Path, and the illusion effects of the Purple Lightning were a joke to him, given his Rinnegan.

Only Obito Uchiha's expression beneath his mask was somewhat grim. He had experienced firsthand the power of Purple Lightning firsthand; he had been ambushed by Sasuke Uchiha using Purple Lightning during the gap in his Kamui intangibility, and had been thoroughly humiliated.

However, things are different now!

A chilling killing intent flashed deep in Obito Uchiha's eyes. Over the past few months, he had diligently studied what Madara Uchiha had taught him, and now he possessed two divine weapons: the Death Scythe and the Flame Fan.

Moreover, at this moment, Tobi, the combat-type White Zetsu, also covered him, enhancing his chakra, strength, speed, recovery ability, nerve reflexes, and a series of other comprehensive abilities.

The power of his Wood Release technique is now only second to that of Hashirama Senju in the past.

Obito Uchiha was confident that he was now in a state where he could fight Sasuke Uchiha head-on.

If it weren't for the need to be absolutely certain, he would have even considered taking matters into his own hands to wash away his humiliation.

As Obito hardened his heart, he heard Black Zetsu continue, "Furthermore, the two other special Sharingan that Uchiha Sasuke possessed also revealed their eye techniques when you and Kazuma were fighting that strange 'Uchiha Mikoto'."

"They are Izanagi, who possesses super-fast regeneration, and Yomijin, a world of the dead that can devour souls!"

Upon hearing this, Kazuma nodded. The names of these two eye techniques were personally told to them by "Uchiha Mikoto," and they had experienced their power and characteristics firsthand in that battle.

Mikoto Uchiha possessed these two eye techniques, so Sasuke Uchiha, who stole her eyes, naturally also possessed them, and perhaps even more powerful ones.

"The Yellow Springs is a technique of time and space. We don't have enough information, so let's leave it aside for now and talk about Izanagi first."

“Izanagi possesses super-fast regeneration, which means that the damage we inflict on Sasuke Uchiha will have almost no substantial effect unless we can deplete Sasuke Uchiha’s chakra during the battle. But we all know that this is a difficult and thankless task, so we can only use another method, which is to use sealing techniques and Yang Release!”

"Based on our investigation over the past few months, we have learned that Sasuke Uchiha obtained his special Sharingan by sacrificing a foreign demon from the Land of Demons to the Box of Elysium. Both of these are vulnerable to sealing techniques. Furthermore, the Sharingan's power is an expression of the ultimate Yin Release. Yin and Yang are mutually reinforcing and mutually restraining. Since it is Yin Release, it will inevitably be restrained by Yang Release!"

When Black Zetsu mentioned sealing techniques and Yang Release, he looked at Pain and Obito respectively.

Because they are proficient in sealing techniques and Wood Release, respectively.

Nagato was born into the Uzumaki clan. Although he didn't know many of the Uzumaki clan's sealing techniques, he had quite a few powerful sealing techniques at his disposal, such as the Nine Seals of the Illusionary Dragon, the Five Seals Barrier, the Mirror Assassin Technique, and the Five Elements Seal.

Among them, Chibaku Tensei is the most outstanding. Chibaku Tensei is the strongest sealing technique in the history of this ninja world, without exception.

Even his mother, Kaguya, was sealed by this sealing technique.

Of course, in addition to these, Nagato's other Paths also have an effect, such as the Human Path's ability to extract souls and the Preta Path's ability to devour chakra.

Given the strength of these two clones, it would be difficult for them to get close to Uchiha Sasuke's body, let alone strike him, so they can be almost ignored.

As for Obito Uchiha, he is now possessed by Tobi, and his Wood Release power, which represents Yang Release, is second only to Hashirama Senju. His attacks can also pose a great threat to Sasuke Uchiha!

Furthermore, his Kamui is also a deadly move; if Uchiha Sasuke were to be accidentally drawn into the Kamui dimension...

As long as he still needs to eat and has normal physiological needs, then no matter how strong he is, if he is locked up for a while, he will starve to death in the Divine Might Space.

"I'll leave the sealing techniques and Yang Release to you and Tobi, leader. As for Kazuma, you'll use the Impure World Reincarnation to assist the two of them and keep Sasuke Uchiha in check."

Upon hearing this, Kazuma, who had once again been relegated to a support role just like in the previous battle in the Land of Swamp, felt somewhat resentful.

He retorted that he had now mastered the Impure World Reincarnation technique and his Impure World army was very strong, so don't underestimate him.

However, Kazuma swallowed his words and nodded.

Although he has now learned the Impure World Reincarnation technique, he has only been learning it for a short time.

Now, being able to summon the previous Lightning Release quartet, the Seven Swordsmen, and the corpse of Hanzo, which he obtained first, is already his limit.

As for the remaining four Mizukage from previous generations, he is now powerless to change them.

Furthermore, Kazuma himself was still somewhat afraid of Sasuke Uchiha, after all, the battle in the Land of Swamp had left a considerable shadow on him.

Staying behind the scenes like this, playing a support role, suits him perfectly.

Therefore, the Akatsuki's tactical arrangement was to have Pain and Obito Uchiha, who was using the alias Tobi, as the main force, while Ma's Edo Tensei army would act as a distraction and support.

The attacks primarily utilize sealing techniques and Yang Release!

After agreeing on their tactics, the Akatsuki members dispersed, setting up traps, barriers, and other obstacles in the area.

............

Within the canyon.

"Is the Grell mine located here?"

At this moment, Sasuke, who had already arrived inside the canyon cave, looked with great interest at the stone platform below the cliff.

"A barrier? Are you afraid I'll escape?"

Sasuke chuckled. He could tell that a barrier array had been set up inside. As soon as he landed, the barrier would activate instantly, trapping him below.

"I'll make sure you don't get your way!"

With a sneer, Sasuke took to the air, entering the "Enlightenment" state with bone spurs growing on his back and wings, transforming into a black streak of light that hurtled towards the seemingly bottomless abyss.

During the sprint, a long sword wrapped in endless, dense black flames suddenly appeared in Sasuke's hand, and the already dark and cold light and temperature around him dropped rapidly.

Sasuke charged faster and faster, his momentum growing increasingly fierce. In an instant, a thunderous roar echoed throughout the entire abyss, causing the earth to tremble!

Just as he was about to reach the ground, Sasuke's charging figure froze for a moment. Then, the black flames that were wrapped around the Fire Armor were instantly transformed into a giant sword that stretched for tens of meters across the sky, and slashed down at the ground with unprecedented terrifying force!

Boom!

The enormous explosion drowned out everything, piercing people's eardrums with pain. Countless pieces of rock shot into the sky, and the surging air currents swept out like a landslide and a tsunami.

With the power of his single strike, the barrier that the Akatsuki had specially set up for him was shattered completely, leaving not a trace!

Of course, the results of his Great Black Heaven's strike were originally far more than just shattering the barrier; the reason it didn't produce a greater effect was because...

That's because Sasuke's attack was blocked!

A massive wooden dragon, nearly a hundred meters long and covered in lush trees, with a long hooked nose and thorns all over its body, tightly gripped the black flame giant blade.

As the countless, inextinguishable black flames burned incessantly on the wooden dragon's body, the vines on its body were also regenerating at a rate no less frantic than the burning black flames.

Wood Release: Wood Dragon Technique!

Sasuke grinned, revealing his gleaming white teeth, as he watched Obito Uchiha, whose eyes blazed with intense killing intent, from behind the giant wooden dragon.

"Long time no see, Obito. Your wood-based technique is pretty good, much improved since last time!"

Meanwhile, at the Takachiho Gorge.

A dark golden light rose from the eastern horizon. At first, it was just a wisp, but in no time, it covered most of the sky. Amidst the howling wind that tore through the clouds, it drew a clear air wave and arc in the air and headed straight for the Takachiho Valley!

Chapter 288 Yinglong's clone arrives.

Underground.

Sasuke seemed to have known they would ambush him here all along, his tone as if he were a hospitable host finally welcoming a long-awaited guest.

"Uchiha Sasuke! You will die today!"

Faced with Sasuke's teasing tone, Obito Uchiha's crimson eyes were filled with a cold and chilling killing intent. Every word he uttered seemed to transform into sharp blades that would pierce through the other's heart!

"Looks like your increased confidence comes from your improved Wood Release, huh?"

Sasuke glanced at the wooden dragon, who was locked in a stalemate with the black flame giant sword, and laughed.

The essence of Black Flame is Fire Release + Yin Release, while Wood Release is Earth Release + Water Release + Yang Release. Strictly speaking, under the same conditions, Wood Release is more powerful than Black Flame.

However, because Sasuke's black flames were also enhanced by a divine weapon, the two sides were evenly matched.

In the previous battle in the Land of Swamp, Obito Uchiha was only able to use mid-level Wood Release ninjutsu such as Wood Release: Wood Wall and Wood Release: Great Forest Technique. This time, however, he used a high-level Wood Release technique like Wood Dragon Technique right from the start.

In Sasuke's view, Obito Uchiha's great progress in Wood Release was due to only two reasons.

First, he spent the last three months reflecting deeply on his mistakes and diligently studying the Wood Release technique.

Secondly, the White Zetsu Tobi, a combat-type character, possessed Obito Uchiha.
