Uchiha Ryo, who believed that the ancestors had fabricated certain deeds, rolled up the first volume of the Bamboo Carving Book and put it aside at his feet, then ignored it. Instead, he took out the second volume and began to read it carefully.
Compared with the unreliable stories in the first volume, the records in the second volume were much more formal. What was introduced first was the ability that every pair of Mangekyo Sharingan possesses - Susanoo.
Susanoo is the ultimate Strength residing in the Mangekyo Sharingan. Strictly speaking, what constitutes Susanoo is not the pupil power, but a manifestation after a large amount of chakra is guided by one's own pupil power and materialized.
Moreover, depending on individuals' different personalities and attributes, it would also present different colors and chakra weapons. It is truly a sharp weapon in battle.
However, there is one thing to note. The pupil power stored in the Mangekyo Sharingan is limited, and the ratio of the Recovery Speed to the Consumption Speed when using pupil jutsu is an astonishing one to ten thousand.
That is to say, the pupil power consumed when using pupil jutsu will take ten thousand times the time it took to use it to recover.
More intuitively, the pupil power consumed by using the Mangekyo for a full hour would require four hundred and seventeen days without using the Mangekyo to recover.
As the pupil power declines, one's own eyesight will also be affected. With high consumption, slow recovery, and a great impact, in this era when people don't live long on average and the combat intensity is high, it is undoubtedly like slapping the word "blindness" in the face of the Uchiha clan.
"Hmm... So is the reason for needing another pair of Mangekyo Sharingan to replace this kind of loss?" Uchiha Ryo stroked his chin. "And the pupil power that can be stored after the fusion of two pairs of eyes should also increase..."
"But why do we need the eyes of blood relatives? Could it be that the eyes retain the owner's will and thus affect the fusion? Or is it that without the same bloodline, normal fusion cannot be achieved? Well... I should find a chance to ask Hiro about this."
"Let me see what's next... Blood Inheritance Disease?"
Opening the Sharingan and the Mangekyo Sharingan prematurely might cause the pupil power to erode the body. After suffering from the Blood Inheritance Disease, one can use Yang - attribute chakra for treatment and relief, but it can't be completely cured. The internal organs will gradually necrotize and lead to death. The best time to open the Sharingan is after the age of ten, and the Mangekyo should be opened even later, at least after the age of fifteen...
"Ah, then it's very likely that I could have suffered from the Blood Inheritance Disease back then... And Uchiha Akihiko isn't even fifteen yet, right? I have to urge him to have a physical examination later. But using Yang - attribute chakra to relieve...
"The ninja clan that uses Yang - attribute Healing Technique... The more well - known one should only be the Uzumaki clan. Our relationship is so poor that it would be very difficult to get treatment from them. Moreover, because they are allied with the Senju clan, there is naturally a lack of trust...
"Could it be that if this situation occurs later, I have to capture an Uzumaki person alive and use genjutsu to control them to assist in the treatment? But most of them probably have Sealing Tags installed in their bodies. Alas - I really don't want to deal with those guys with all kinds of strange methods."
Uchiha Ryo's expression grew a bit morose. He read through the contents over and over again, but in the end, he could only heave a sigh. He carefully rolled up the Scroll and placed it on the desk before reaching for the next one.
Compared to the first Scroll, which was nothing but an annoyance, the second Scroll contained so much useful information that Ryo couldn't absorb it all at once. He decided to keep it properly and read it later.
The third Scroll described how to love someone and then kill them to awaken the Mangekyo Sharingan, or how to commit suicide to trigger the awakening in a loved one.
In summary, it taught those seeking to awaken the Mangekyo to deliberately create tragedies to gain Strength. It also suggested that to ensure obtaining this Strength, one should have many offspring and, if necessary, even take a child's eyes. After reading it with great patience, Ryo rolled it up and tossed it to his feet, just like the first one. It was another useless piece of junk.
He thought about how Uchiha Akihiko, who used to be so positive, had become so pessimistic. It turned out that these unreliable ancestors were deliberately leading him astray. As ancestors, shouldn't they try to solve Mondai for their descendants? Instead of solving them, they were creating more Mondai. Did they want the clan to go extinct?
When he opened the fourth Scroll, it recorded various medical knowledge about eyes, including the extraction, transplantation, and preservation of the Sharingan. Ryo skimmed through it and then rolled it up again and placed it on the desk. Everyone had their own specializations. This Mystical Palm Technique didn't suit him. He'd give it to Hiro to learn later and just understand it briefly himself.
Just as he finished reading this Scroll and was about to reach for the fifth one, Uchiha Akihiko arrived with a Ninjutsu Scroll. After they exchanged greetings, Akihiko cast a glance at the two Bamboo Carving Books lying on the floor. "Are the first and third Scrolls useless?"
"It's just a load of rubbish," Ryo grumbled as he unrolled the fifth Scroll, looking uncharacteristically vexed. "It's enough to just understand what's on them. Only a fool would take it seriously. By the way, give the fourth Scroll to Hiro when you leave. Ask him to send it back to me after he's learned it."
"Sure," Akihiko nodded. As he watched Ryo's hand caressing the engravings, he went on, "After the fifth Scroll, it records individual Mangekyo jutsu and the process of awakening. I engraved all the parts that were still legible. Just take your time reading it. This part is quite interesting."
Ryo nodded slightly. "Okay, I'll ask you if I have any questions."
After that, the two of them each sat on one side of the desk. One was carefully engraving on the Bamboo Carving Book, and the other was delving into the ninjutsu recorded in the Ninjutsu Scroll. They would exchange opinions from time to time, creating a rather peaceful and idyllic atmosphere.
As time passed, Ryo finally finished reading all nine Bamboo Carving Books. The odd and powerful eye jutsu recorded in those Bamboo Carving Books even made Ryo wonder if the Uchiha ancestors had some ties with the Uzumaki clan.
What surprised Uchiha Ryo the most was that there were almost no repeated eye jutsu among those recorded ones. There were at most three or four repeated ones among a hundred eye jutsu, and these repeated eye jutsu belonged to different owners. Moreover, due to the different personalities of these owners, they were used in different ways.
[Finally, I get why the traditional Gitai of the Uchiha clan members love to show off their skills.] Uchiha Ryo sighed softly, itching with excitement. [Who wouldn't go all out in combat with these eye jutsu?]
Tsk. I was too hasty back then. I should have awakened the Mangekyo to experience it before going blind... Come to think of it, wasn't I in an extremely intense emotional state even when I was on the verge of death?
Hmm—There are still many Doubts about the Mangekyo Sharingan.
