The moment he had come into contact with Tsunade earlier, Yuzhen had directly given the system an order.
Extract the Senju of the Forest's Kekkei Genkai Affix!
The Entry Extraction System had not let him down. He had obtained the Senju's bloodline power!
[Senju of the Forest (Blue)]: The powerful bloodline that the Senju of the Forest wielded was proof of their possession of the God Tree's power!
Effect: Chakra and vitality greatly enhanced.
"Blue? Still, it'll do!" Yuzhen stared at the blue Affix on the panel and muttered to himself.
He quickly accepted the result.
It was perfectly normal for Tsunade's Senju of the Forest bloodline Affix to be blue.
In the original story, her Kekkei Genkai only increased her chakra reserves.
She didn't have Wood Release, and she relied on Medical Ninjutsu to heal her injuries.
But... he was different!
With the system, all he had to do was reach the required number of Combat Points to upgrade this bloodline Affix.
And he knew full well how important the Senju of the Forest bloodline was to the Uchiha's Sharingan!
With that thought, Yuzhen's mind stirred.
"System, install the Affix!"
As the Affix was installed,
a warm sensation rose from within Yuzhen's body.
"What's this?" Yuzhen was a little incredulous.
He felt a surging vitality slowly welling up from deep inside his body.
The information on the panel reflected it, too.
A new Affix appeared on the system panel, one he hadn't extracted from anyone.
It had appeared out of thin air!
[Yang Release (Green)]: A chakra nature and proof of vitality!
Effect: Through specific techniques, the user can heal themselves or other living beings.
"Yang Release? This must have appeared after I installed the Senju bloodline Affix."
But when Yuzhen looked at the complicated list of chakra nature Affixes on his panel,
he felt a headache coming on...
If only the system could combine all these nature Affixes.
After all, no matter how chakra's nature changed,
it was still chakra.
Besides, the Otsutsuki Clan didn't divide chakra into different natures.
It seemed to sense Yuzhen's thoughts.
The Entry Extraction System in the sea of his mind trembled faintly.
A stream of information flowed into Yuzhen's mind.
"Hm? Affixes can be combined?! But it takes Combat Points?"
"The higher the compatibility between the Affixes, the fewer Combat Points it costs. The lower the compatibility, the more it costs!"
Uchiha Yuzhen immediately perked up.
There was nothing to think about!
He had already wanted to simplify the chakra nature Affixes.
Besides, everything supernatural in this world was based on chakra.
That included the Otsutsuki!
All of their abilities...
Immortality, simulating the myriad phenomena, controlling space-time, creating worlds, establishing the netherworld, manipulating life and death, creating objects from nothing, traversing the sea of stars, and so on.
They all relied on chakra!
"System, how many Combat Points does it take to combine the chakra nature Affixes?"
The system answered its host's question with a stream of information.
"Since they're all derived from chakra's transformations, their compatibility is very high. It only takes 100 Combat Points?"
He had exactly 170 Combat Points.
He focused his thoughts.
The chakra inside his body began to churn.
After the time it took to drink a cup of tea, Yuzhen's chakra gradually settled.
But his attention had already shifted to the panel!
Host: Uchiha Yuzhen Gender: Male Age: Twelve Strength: Kage Affixes: [Child of Time and Space (Gold)], [Genius (Gold)], [Phantom Fate (Gold)]. [Uchiha (Purple)], [Steel Training (Purple)], [Mangekyō Sharingan (Purple)]. [Senju of the Forest (Blue)], [Uchiha Style (Blue)], [Natural Energy Affinity (Blue)], [Flying Thunder God Technique Formula (Blue)], [Vampiric Immortality (Blue)], [Medical Genius (Blue)], [Chakra Seed (Green)]. Combat Points: 70
Yuzhen noticed that the Ninjutsu chakra Affix had disappeared.
A new green Affix had appeared.
[Chakra Seed (Green)]: This is the source of your own chakra!
Effect: Simulates Yin-Yang and Five Elements and allows them to be combined and transformed.
Current transformation—Scorch Release!
"Simulates Yin-Yang and Five Elements? Combines and transforms them?"
As if he had thought of something, Yuzhen raised his left hand and concentrated chakra.
Hum—!
Blue chakra appeared in his hand.
"Good thing I've seen Kakashi use Lightning Style chakra activation so many times. The flow of chakra goes like this..."
As Yuzhen recalled how Kakashi used Lightning Style, something he had seen through his Sharingan,
the chakra in his body began to move, too.
Crackle!
Thin arcs of lightning appeared in his hand.
"Hahahaha! Just as I thought! Those 100 points were well spent. I can still use Scorch Release, and the system directly produced Lightning Style chakra!"
There was no need to mention Earth and Water. The Scorch Release he'd extracted in the first place was a fusion of the two.
And he had installed the Senju Kekkei Genkai Affix as well.
The Senju's standard chakra natures were Earth and Water!
Yuzhen could also feel surging vitality continuously gathering in his eye sockets.
A faint coolness enveloped them, making him feel as if a restraint on his eyes had been loosened.
But he knew from the [Uchiha (Purple)] Affix that bloodline Affixes
needed time to prove their effects. They wouldn't work immediately.
The fact that he could feel a change in his body now was a good sign!
The important thing now was to study Medical Ninjutsu.
Yuzhen abruptly cut off his thoughts.
He began to study the massive textbook Tsunade had given him in earnest.
Time flew by, and before long, the day Yuzhen had to go on a mission arrived.
Early that morning, just as the sky began to brighten,
Yuzhen got up and washed.
He set off for Konoha Hospital very early.
His mission was scheduled for the afternoon.
He had already arranged with Tsunade that she would check his progress first thing that morning.
He wanted to see how far Yuzhen had come.
Before long,
Uchiha Yuzhen arrived at the room, knowing the way by heart.
He found Tsunade already there, waiting for him at the table.
Seeing that Yuzhen had arrived early and hadn't been late,
Tsunade nodded in satisfaction. "You're punctual, Yuzhen. Good. Come over... I'll check how much progress you've made."
"Yes, Teacher Tsunade."
The assessment went smoothly, and Tsunade was quite satisfied.
"Good. Your theoretical knowledge is impeccable, too. Now let's see how well you can put it into practice."
With that, Tsunade stood up.
"Follow me, kid."
Yuzhen obediently followed her.
They arrived at a room that looked like a laboratory.
Tsunade went over to a workbench.
She took a fish from the tank beside her.
Whoosh—!
Tsunade cut the fish with a scalpel.
"Come here, kid. Use the Mystical Palm Technique to heal this fish."
She wanted to see whether Yuzhen had improved at using the Mystical Palm Technique after studying it.
Yuzhen did as he was told, not giving it much thought.
He went over to the injured fish.
He formed the hand seals, and the green healing chakra of the Mystical Palm Technique appeared.
"Hm?" Tsunade looked a little puzzled.
As Yuzhen displayed the Mystical Palm Technique, the necklace around her neck
trembled slightly.
She thought she must have imagined it.
But when Yuzhen's hand touched the fish and he increased his chakra output,
Tsunade sensed something different.
It wasn't just the necklace!
Even her chakra began to react to his.
Tsunade seemed to have thought of something unbelievable.
Smack—!
She grabbed Yuzhen's arm.
