Now that it has been noticed by Uchiha Madara, it is necessary to prevent White Zetsu's prying eyes!
So...
[Natural Energy Affinity (Blue)]—this entry must be strengthened to the level of a purple entry.
Yuma believes that entries at this level will make it much easier to capture natural energy. He plans to use this to develop his own Sage Mode.
Sage Mode, coupled with perception ability, has been shown in the original work to allow detection of White Zetsu!
Thinking of this, Uchiha Yuma was truly moved. The combat value fluctuated for a moment. After consuming one thousand points, his value dropped from 2570 to 1570. Correspondingly, the enhanced entries also underwent changes.
[Natural Energy Affinity (Purple)]: You are integrated with nature!
Effect:
Natural energy can be easily absorbed into your body. Chakra grows massively. Nature will not retaliate against you.
"Sure enough... the entry system is extraordinary!" Uchiha Yuma was extremely excited.
If the effect of this entry was really as the system displayed, his Sage Mode would probably not take long to achieve.
He could capture natural energy easily, and would no longer need to worry about the backlash from nature.
After returning home, Yuma planned to experiment with the ratio of natural energy to Chakra. Sage Mode was inevitable!
"Next..." Yuma, extremely excited, immediately looked at the entry panel. The entries related to natural energy gave him such a huge surprise, he still had a surplus of combat value and wanted to keep trying.
The next entry he wanted to upgrade was the one that would truly bring about a qualitative change for him!
An idea crossed his mind, and combat value was consumed.
Senju's blood inheritance limited entry changed from blue to purple.
[Senju of the Forest (Purple)]: The bloodline of the Senju will be carried forward in your hands!
Effect:
Vitality and Yang Style are greatly improved. The buds of 'wood' will bloom in your hands.
The combat value continued to decrease. 1570 became 570.
However... Uchiha Yuma didn't care about the costs anymore. He was thinking about the changes this upgrade would bring!
He impatiently ordered the system, "Install the entry!"
Buzz!!!
The moment the system installed the upgraded entry into his body, Uchiha Yuma felt everything change...
Bursting vitality erupted from within his body. Yang Style Chakra flowed from the wheel of life in his lower abdomen very intuitively...
This Chakra, after merging with the life force, traveled straight to his eyes!
Before Yuma could react, the energy reached his eyes.
"Hiss~" Uchiha Yuma felt a chill brewing in his eyes. "This feeling... has the vision of my left eye recovered?"
In that battle, his left eye's vision had been impaired after using the "Ichimokuren" pupil surgery. It took too long to recover even with the blue-level Senju bloodline entry.
But now, with the upgrade to the purple entry, his eyesight had completely returned!
"It seems that the Senju Bloodline in me has reached the same level as the White Zetsu cells in Obito. They are both at a level where I can use Mangekyō's power freely!"
Yuma was filled with emotion. Mangekyō's pupil technique is easy to use, but for Uchiha, it was only useful if the eyes didn't deteriorate.
But now, this problem would never bother him again. He would be like Uchiha Obito in the original story, using his eye techniques without any worry about blindness!
"Not only that..." Yuma noticed that there were other changes in himself. He raised his hand and said, "I think I can do this?"
As soon as he finished speaking, a tree branch sprouted from the ground under his palm...
In a short period of time, the branches grew into giant trees.
"Wood Style... This is the bloodline limit that rivals the Sharingan for a thousand years!"
Yuma didn't have the Wood Style printing method, but he could still make the land grow large trees.
There's no way he couldn't do it!
Yamato could do that. It made sense that the purple-level Senju bloodline entries couldn't do less!
However, Yuma felt a sense of pride. The power of his current Wood Style was about the same as Yamato's.
While it was fine for some greening, it would be difficult to fight against tailed beasts with it.
But Yuma didn't care and immediately turned his attention to the change in another entry.
"Only after returning to Konoha will I be able to practice carefully to sense the changes in natural energy."
The changes brought about by the upgraded natural energy entry weren't fully felt yet. Chakra had indeed experienced some growth, but the upgrades to his Senju bloodline caused a surge in Chakra due to increased vitality.
This change was much more noticeable!
Yuma didn't need to talk much about this aspect for now, but he could feel that his Chakra would experience huge growth soon.
As for being close to nature and capturing natural energy...
That would require calm meditation, and since he was still on his way, he planned to experience it once he returned.
"There is only one entry left to upgrade."
Without further delay, he upgraded the final entry.
[Chakra Seed (Green)] became...
[Chakra Seed (Blue)]: The source of Chakra that belongs to you alone; no one can take it away!
Effect:
Simulates Yin Yang and the Five Elements, allowing for merging and changing. Variations—Lava Style, Wood Style.
As soon as the entry was installed, Yuma could feel the difference.
His own elemental techniques would be strengthened!
The blue-level entries all represented the degree to which they could be used in combat. He had already figured out the so-called Chakra seeds.
"The source of Chakra that belongs to me is my Chakra. It is no longer Kaguya-hime's Chakra." Yuma thought thoughtfully. The upgraded entry gave him a deeper understanding.
His Chakra source represented the power he would wield in the future. This power would increase by more than 20%.
The reason was simple. The Chakra he had been using before was also Kaguya Ōtsutsuki's!
There was no doubt about this!
While Chakra was nominally refined by the ninja themselves, it was made very clear in the later parts of Shippuden that it all came from the Sage of Six Paths, Ōtsutsuki Hagoromo, from the Ten Tails.
"Huh~" Yuma breathed a sigh of relief.
Although his combat value had decreased from 2570 to 470, the expense was worth it.
He believed that after returning to Konoha, and after a period of practice to digest the upgraded entries, his strength would drastically change.
Not only would his strength grow, but all aspects of his abilities would also be greatly enhanced!
Clang!
Yuma drew out his ninja sword.
"Next, it's time to change my weapon!"
