Hashirama didn't have any hidden injuries either; strictly speaking, he could still run and jump even at a hundred years old.
His death was purely because he no longer wished to live.
Otherwise, even after half a century, Hashirama's cells wouldn't still possess such powerful vitality.
This kind of person is the most shrewd. When a centenarian next door has a funeral, they insist on barging in, claiming they need to absorb some hundred-year soul ring.
Ryou transplanted Hashirama cells, and now he can learn all Wood Release techniques except for Senjutsu level ones.
For example, the Wood Golem Technique and Wood Dragon Technique are both powerful Ninjutsu on par with the Perfect Susanoo.
Now, about the Sharingan.
Ryou pressed his eye sockets, and his powerful dōjutsu power directly materialized into the first form of Susanoo.
This is the gift brought by Madara's cells, the ultimate power of Yin Release, the Sage's Eyes of Indra.
The purest Chakra and spiritual energy.
Madara's current eyes are at the highest level, the Rinnegan, inheriting the strongest dōjutsu power of the Sage of Six Paths
Madara's lineage has still degraded quite a bit. If it were Indra, Ryou could activate the Perfect Susanoo with just a three tomoe Sharingan.
According to the setting in the Jin no Sho, Indra was born with extremely powerful dōjutsu power.
He could activate the Perfect Susanoo with just three tomoe.
That wasn't the three tomoe Sharingan as defined by the Uchiha Clan, but a three tomoe Eternal Mangekyo.
Although Ryou hasn't awakened the Mangekyo, his eyes are already infinitely close to Indra's, evolving towards Indra's ultimate dōjutsu power.
The Uchiha method of evolving the Sharingan into a Mangekyo by killing a loved one was an evil path to begin with.
In the manga's setting, Indra's Sharingan was innate, not some random TV creation where it was awakened through Black Zetsu's guidance.
Also, the Sage of Six Paths did not have a Sharingan; his Sharingan was also a random TV anime original.
His father wasn't some Emperor of the Land of Ancestors either. Both the Sage of Six Paths and Hamura were products of Ōtsutsuki Kaguya's asexual reproduction.
They are pure-blooded members of the Ōtsutsuki Clan.
The Sage of Six Paths was born with the Rinnegan. Just like Madara's Rinnegan, techniques like Susanoo are Rinnegan Dōjutsu.
Kaguya only realized that most of her power had been inherited after seeing the Sage of Six Paths's innate Rinnegan, which is why she wanted to take back the Chakra from Hagoromo and Hamura.
Indra's Sharingan is a regression of the Rinnegan.
Through generations of regression, the Uchiha Clan's lineage weakened to the point where they could only awaken the Sharingan through extreme emotional distress.
To the point that they had to witness the loss of a loved one to awaken the true power of the Uchiha Sharingan.
Indra didn't need any of those bells and whistles; he had the strongest dōjutsu power from birth.
Ryou's current dōjutsu power is exactly like that; his eyes are already in a permanent three tomoe state.
What does that mean?
It means the tomoe can no longer be hidden. The three tomoe is just how his eyes look now; this is the true evolution of the Sharingan.
The Sharingan usually requires Chakra to activate, otherwise it reverts to normal eyes. That's not evolution, but a transformation like a Super Saiyan.
Madara was the same. In the original work, when he was reincarnated through Edo Tensei, his eyes were in the three tomoe Sharingan state, proving his eyes had already evolved to a permanent three tomoe state.
Conventional Genjutsu is just a basic attack for eyes like these; a single glare at a Jonin would be enough to make them 'pregnant'.
Ryou's eyes haven't awakened the Mangekyo, but his dōjutsu power is comparable to one. This is a Three-Tomoed Mangekyo.
He just lacks the essential Dōjutsu of the Mangekyo Sharingan, like Tsukuyomi, Amaterasu, Kamui, and the like.
It can't be helped. After a thousand years, the Uchiha lineage has declined significantly. One must experience extreme emotional stimulation to awaken the techniques hidden within the Sharingan.
Or perhaps the original Sharingan didn't have these special abilities to begin with. These things like Tsukuyomi and Kamui are all obtained by sacrificing kin and loved ones.
It's an evil path!
Ryou hopes he never obtains the kind of power gained by sacrificing kin and loved ones in his entire life.
Basically, the moment he awakens the Mangekyo, his eyes will be the Eternal Mangekyo.
First, he possesses the massive dōjutsu power to activate Susanoo with just three tomoe.
Second, he has Hashirama cells, and the power of Yang Release can nourish the dōjutsu power within the Sharingan.
There will never be a situation where the Sharingan's dōjutsu power is exhausted.
"I have shed my snake skin and ascended into a dragon!"
Now, Ryou's Chakra has soared to the level of a Tailed Beast, his Sharingan's dōjutsu power is comparable to a Mangekyo, and his Monster Strength is now his basic attack.
And then there are his Life Spores!
By fusing Madara and Hashirama's cells, his physical constitution has increased tenfold, and he can now accommodate fifty Life Spores.
In other words, he has fifty lives.
As long as he protects his head and isn't sealed or hit by a soul attack, Ryou is immortal.
Moreover, even if his heart is injured, he can regenerate quickly. He's even harder to kill than before.
Ryou has already surpassed the Sannin and is approaching the level of Madara and Hashirama. He has become completely arrogant, unconsciously starting to look at people out of the corner of his eye.
Just like Sasuke in the original work when he first awakened the Mangekyo, he'd probably slap a dog on the side of the road twice just for being there.
Madara tossed a scroll to Ryou: "These are Hashirama's Wood Release Secret Techniques. You can learn all of them except for the True Several Thousand Hands and the Top Transformed Buddha."
Ryou took the scroll from Madara and created a dozen or so spore clones to take the scroll and practice the Wood Release Secret Techniques.
Ryou then walked over to Madara's side with his arms crossed.
Madara looked at Ryou and said, "Now that you've learned Hashirama's Wood Release, no one in the Ninja World will be your match anymore. I'll leave the Shinobi Allied Forces and the Nine Tailed Beasts to you."
Hashirama's Wood Golem Technique is on par with the Perfect Susanoo, and then some. Even if Madara combined with the Nine-Tails to activate the Majestic Attire: Susanoo, he couldn't defeat Hashirama's Wood Golem.
As for the Senjutsu: Wood Release: True Several Thousand Hands that stands above the Wood Golem Technique...
Even Madara couldn't learn that kind of technique.
Back then, as soon as Hashirama activated his True Several Thousand Hands, Madara's Majestic Attire: Susanoo Nine-Tails was instantly brought down.
Even with the Rinnegan, Madara felt a hint of trepidation when facing the Senjutsu: Wood Release: True Several Thousand Hands.
The Wood Golem is on par with the Perfect Susanoo, while the Thousand-Armed Kannon already possesses power close to that of the Sage of Six Paths
The Wood Golem isn't even as large as the head of the Thousand-Armed Kannon.
Madara would need to become the Ten-Tails Jinchuriki and activate Six Paths Mode to completely suppress Hashirama's Thousand-Armed Kannon.
During the Warring States Period, why was Hashirama the God of Shinobi while Madara was just Madara?
Because Hashirama suppressed Madara for his entire life!
As Madara was talking, he suddenly felt something was off because this kid Ryou was looking at him sideways with his arms crossed.
Ryou patted Madara's shoulder and said very familiarly, "Madara-chan, don't you worry. Just leave the Nine Tailed Beasts and the Five Great Ninja Villages to me!"
"I've paid for your social security in Amegakure; you can just enjoy your retirement from now on!"
Madara-chan?!
Nagato, Konan, and Tsunade's eyes widened, and they all stepped back together to avoid being splattered by Ryou's blood.
Candy was dismantling nearby wooden boards to make a coffin for Ryou.
Meanwhile, Fish Ball and Fortune had already started dividing up the estate; they even started fighting because of the unfair distribution of the loot.
Madara looked at the hand Ryou had placed on his shoulder and laughed out of anger. "Good, good, what a fine grandson! A fine son of my Uchiha Clan!"
Ryou nodded. "Of course. Who doesn't know that I, Uchiha Ryou, am filial?"
"Madara-chan, you're an old bachelor with no wife or kids, it's quite pitiful. Now that I've transplanted your cells, I can be considered to have your blood flowing in me."
"I'll take care of you in your old age from now on."
"You're already eighty years old, so just stay home and relax! Stop trying to go out and kill people like the youngsters do."
"You little brat—"
Ryou wanted to continue, but Madara pressed a hand against his face. Madara's immense strength combined with the powerful repulsive force of the Rinnegan took effect.
Ryou was blasted right out of the office building, flying towards the outskirts of Amegakure.
Madara simply held Ryou's face and flew towards the edge of the village.
Is it that you, Ryou, have become too arrogant, or is it that I, Madara, can no longer swing my blade?
