Over the next week, Uchiha Yan was so busy he barely touched the ground.
He either stayed at Kushina's house, burying himself in the deeper mysteries of those Sealing Jutsu while working with Tsunade to refine the subsequent Medical Talismans.
Or he holed up in his laboratory at home, stubbornly studying Kushina Uzumaki's blood samples with his instruments.
At the same time, he got in touch with the Nara Clan and contacted other medicinal herb merchants. The first batch of herb deals went through smoothly.
He also signed long-term secret medicine supply contracts with the Ino–Shika–Cho Trio and the Sarutobi Clan.
What they mainly ordered were the two kinds of Body-Tempering Pills and the delicious Military Ration Pills.
The demand was anything but small.
Today, the Uchiha Secret Medicine Shop at Uchiha Yan's home officially opened for business.
He had originally wanted to keep away from the commotion, but his parents insisted on dragging him over. With Mikoto and Kushina also clamoring to see the excitement, he had no choice but to bring the two girls along.
"Wow! It's packed!"
"The line to buy things is so long! Xuan, your family is going to make a fortune!"
Kushina leaned over the second-floor railing and looked down at the tightly packed crowd below, unable to stop herself from crying out.
Uchiha Yan smiled faintly. "Money doesn't matter to me. Whether I earn more or less, it's all the same."
"Eww... is this what you meant by showing off? Hehe!"
Seeing his expression, Kushina could not resist slinging an arm around his shoulders and teasing him affectionately.
Mikoto, standing beside them, showed little reaction.
She was used to it by now.
Over the past few days, she had often run into Kushina being lovey-dovey with Xuan, so she no longer thought much of it.
In Mikoto's eyes, Uchiha Yan was simply too dazzling. A man like him was not someone she could keep all to herself.
Having Kushina share the burden was not necessarily a bad thing.
"Hm?"
Uchiha Yan suddenly sensed a strange gaze fixed on him and Kushina.
Following the feeling, he turned his head.
At a glance, he spotted a blond youth with a sunny, handsome face, currently staring at the two of them with a look of deep disappointment.
"Minato Namikaze?"
Uchiha Yan recognized him immediately.
He smiled at Minato and gave him a polite nod.
Minato was visibly stunned.
Then he returned the gesture with a courteous nod.
After giving Kushina one last glance, Minato withdrew his gaze, grabbed a bottle of Military Ration Pills and a small bottle of Body-Tempering Elixir, then squeezed through the crowd and quickly left.
So this is the person you chose, Kushina?
He really is outstanding.
I was too foolish. My stupid actions caused misunderstanding after misunderstanding between us, and that was how I lost you.
I hope you'll be happy.
If he ever dares bully you, I absolutely won't let him off!
On the way back, Minato silently made that vow in his heart.
At the same time, he made up his mind to train even harder under his teacher, devoting more of his energy to becoming stronger.
No one knew better than he did how cruel the Ninja World was.
Only with enough strength could he firmly seize future opportunities when they came.
And only then could he protect the family and friends around him.
Three months later.
Inside Xuan's underground laboratory.
[Through extensive experiments and observation, you have completely uncovered the mysteries of the Uzumaki Bloodline. Combining the essence of the Innate Art and the Sharingan Cultivation Technique, you suddenly achieved enlightenment and created the Uzumaki Sage Body Cultivation Method and the Bloodline Technique: Kagura's Mind's Eye Cultivation Method.] [Uzumaki Sage Body Cultivation Method]: Using a drop of Uzumaki clan blood as a catalyst, cultivate step by step to strengthen the power of the bloodline and enhance vitality. Upon reaching mastery, you can obtain a complete Uzumaki Sage Body, gaining astonishing vitality and a longer lifespan. [Bloodline Technique: Mind's Eye of the Kagura]: Likewise using Uzumaki blood as a catalyst, cultivate to gradually master the divine ability of the Mind's Eye of the Kagura. Practicing it together with the Uzumaki Sage Body Cultivation Method produces better results. Those with the Uzumaki Bloodline can also use this method to awaken the Mind's Eye of the Kagura.
"Hahaha! I finally did it!"
Feeling the two complete sets of ** techniques fully deduced in his mind, Uchiha Yan could not help throwing back his head and laughing.
"It really wasn't easy! It took me three whole months, but my efforts finally paid off."
As he absorbed the contents of the two ** techniques in his mind, he felt every bit of effort had been worth it.
He immediately took out a drop of Kushina's blood, treated it with a special method, and swallowed it directly.
He sat cross-legged and began circulating the Uzumaki Sage Body Cultivation Method, directing the chakra within his body.
More than ten minutes later, Uchiha Yan refined that treated drop of blood and condensed it into a bloodline seed.
The seed traveled through a complete major circulation before settling into his heart.
From then on, whenever he circulated the technique, he absorbed and refined natural energy from the outside world through his breathing, slowly nourishing the seed and letting it grow bit by bit.
Under normal circumstances, it would take quite some time for the bloodline seed to sprout, grow, and finally mature completely.
But Uchiha Yan was different. His physique was already strong and his vitality abundant. On top of that, he cultivated the Innate Art, and his body contained a large amount of Innate Qi.
He could directly use Innate Qi to ripen the process.
As soon as he thought of it, he acted. He immediately mobilized the Innate Qi in his lower dantian, transported it into his heart, and continuously injected it into the Uzumaki bloodline seed.
After absorbing the endless stream of Innate Qi, the Uzumaki bloodline seed began expanding like mad.
"Crack, crack—"
In just a few minutes, the seed began taking root and sprouting, then rapidly grew larger.
Three hours later, Uchiha Yan had used up ninety percent of the Innate Qi in his lower dantian before finally stopping the transfer.
While circulating the Innate Art to restore his depleted Innate Qi, he observed the Uzumaki bloodline seed within his heart.
No, it could no longer be called a seed now. It should be called a bloodline tree.
Every moment, this bloodline tree absorbed blood and strengthened it, gradually bringing Uchiha Yan's blood closer to that of a true Uzumaki Clan member.
At the same time, driven by the Uzumaki Sage Body Cultivation Method and the blood's own circulation, the vitality and Uzumaki physique pheromones contained within the new blood began seeping into every cell of Uchiha Yan's body, rapidly transforming his physique.
His vitality surged along with it.
Even his height increased by nearly two centimeters in a short time.
Later, as the Uzumaki Sage Body gradually took shape and continued to grow, his physique would improve even faster, and his body would continue growing as well.
For the entire next month.
Uchiha Yan devoted most of his time and energy to cultivating the Uzumaki Sage Body, continuously using Innate Qi to speed up the process.
[You used Innate Qi as nourishment to accelerate the growth of the Uzumaki Sage Body. Your Uzumaki Sage Body has reached completion, attaining the peak state of Kushina Uzumaki's bloodline.] [Your Mind's Eye of the Kagura received nourishment from the bloodline, causing its proficiency to surge. It has risen to the completion level.]
The Uzumaki Sage Body, which originally would have taken years or even over a decade to cultivate, had been forcibly shortened to just over a month and brought straight to completion.
The Uzumaki bloodline tree in Uchiha Yan's chest had completely vanished.
More accurately, it had thoroughly merged into every corner of his body.
Of course, as long as he activated the Uzumaki Sage Body Cultivation Method, the phantom image of a rotating bloodline tree would still appear around his heart, continuously exhaling and absorbing power.
Thanks to his completed Uzumaki Sage Body, the boy's height shot up to one meter twenty.
His physical fitness had also been forcibly raised to the threshold of a taijutsu Jōnin.
Most outrageous of all was his vitality—it had increased by more than tenfold.
He had even cultivated something like the Mind's Eye of the Kagura to completion ahead of time.
"What a pity. Kushina's bloodline purity is only at that level, so this is as far as I can go for now."
He clicked his tongue, considering his next move.
To go any further, he either had to obtain Uzumaki Clan blood with greater purity and complete his bloodline;
Or he had to create an Uzumaki Bloodline Purification Technique himself and rely on his own abilities to purify and optimize it.
He acted as soon as he made up his mind.
Without another word, Uchiha Yan closed his eyes and began deducing and comprehending it.
