Uchiha Gene Fluid

"Yayoi, what's gotten into you? Have you been avoiding me these past few days?"

Shengshu rushed over and slung an arm around Yayoi's neck.

"No, I really have something urgent to take care of."

At noon, Yayoi had lunch with Yan, then planned to buy some Pure Gold and jade materials.

But, unfortunately, he ran into Shengshu.

"I've had a few things to deal with these past few days."

Yayoi rubbed his forehead helplessly. Shengshu was far too enthusiastic.

"All right, then. But if you need anything, you can ask me for help."

Seeing that Yayoi didn't seem to be making excuses, Shengshu nodded.

After all, Yayoi was always more mature and reliable than him. Without even realizing it, Shengshu had come to believe that whenever Yayoi said something like that, he must have something important to handle.

"Yeah. If I run into something I can't deal with, I'll definitely ask you for help."

Yayoi said jokingly.

"By the way, Shengshu, this is a gift for you. Be careful on the battlefield, and don't keep charging ahead."

Yayoi handed Shengshu the incomplete Alchemical item he had made earlier.

Yayai had no use for the thing, and neither did Yan. Rin certainly didn't need it either.

Yayoi didn't have many friends, so he decided to give it straight to Shengshu. He hoped he wouldn't die on the battlefield.

"Uh, why does it just look like a long bar? It's not pretty at all."

Shengshu said disdainfully.

He also couldn't agree with Yayoi telling him not to charge into the front lines.

He was a member of the Senju Clan, and the First's grandson. Of course he had to fight on the front lines for the village his grandfather had worked so hard for.

"You have to take it with you. Otherwise, I'll tell Tsunade-sensei you snuck off to the red-light district with Lord Jiraiya."

Seeing Shengshu's disdain, Yayoi put on a stern face.

"I'm sorry! I'll keep it with me and take good care of it."

As soon as Shengshu heard that Yayoi was going to report him for going to the red-light district with Jiraiya, he immediately backed down.

"Train hard lately. Don't die."

"Yeah. I'm a man who's going to become Hokage someday."

That afternoon

After saying goodbye to Shengshu, Yayoi used the money Rin and Yan had given him to buy gold and jade from the shops.

Then he returned to the basement from earlier and put all the instruments and equipment into storage scrolls.

He hurriedly gathered all his belongings and headed to Yan's house, drawing curious looks from passersby.

Even Yayoi's usually thick skin couldn't stop him from blushing under everyone's stares.

Perhaps it had something to do with what he was about to do.

After all, this really did make Yayoi feel as if he were compromising his moral principles.

He found the room he and Yan had agreed on and started sorting through the clutter.

An hour later

When Yan came home from school, she found Yayoi there as promised, standing quietly in the room and watching him busily work.

"Yayoi-kun, are you really going to live here?"

Yayoi could clearly sense Yan's excitement and delight, and his heart warmed.

At least Yan really did care that he was coming over.

"I'm just moving my lab here. Everything else will stay where it was before."

As he unsealed the scrolls, Yayoi tidied up the room.

Some of the scrolls held his parents' belongings, while others were ones Yan had given him.

In any case, Yayoi planned to move all his precision instruments and equipment into Yan's house.

"That's fine, too. I'm already very happy."

Yan watched Yayoi working and smiled tenderly, though inside, a storm was raging.

She was thrilled, but now that it was actually happening, she hadn't expected it. Even today, she'd thought Yayoi-kun was joking with her.

But did this count as living together?

Would they have a child if they lived together? What would she name her baby with Yayoi-kun someday?

By the time Yayoi finished moving everything, Yan had nearly imagined herself vacationing with their child in the Land of Fire and eating dango.

"Are you feeling unwell?"

Seeing Yan's flushed cheeks, Yayoi asked.

He didn't know why she had suddenly blushed. Could it be a woman's menstrual cycle?

But Yan wasn't even ten yet.

Could the physical constitution of the Ninja World affect that, too?

Yayoi felt he'd found something else worth investigating.

Year 36 of Konoha

Several years had passed since the war between Konoha and Sunagakure.

The two armies had fought for a full two years.

Ninja casualties were devastating. Even Jonin had fallen one after another, and the losses were immense.

Konoha was hit especially hard. The war with Amegakure had just ended, and barely a year later, it was dragged back into the quagmire of war.

What was more, the enemy leading the war was the Kazekage, in the prime of his life and at the height of his strength. He was called the strongest Kazekage in history.

White Fang was the only one on Konoha's side who could stand against him.

Fortunately, Konoha had no shortage of talent. After one victory after another, the balance of the war gradually tipped in Konoha's favor.

On top of that, the Sannin repeatedly distinguished themselves on the battlefield, further thwarting Sunagakure's schemes.

Tsunade, in particular, countered all sorts of poisons from Chiyo of Sunagakure, single-handedly neutralizing the village's most powerful weapon.

This achievement greatly boosted their side's morale.

Sunagakure hated her to the bone, while Konoha hailed her as a hero.

This was the third year.

It was also the year Yayoi graduated.

"Yayoi-kun, it's graduation day! Hurry up and come out."

"Yeah, I'll be right there."

Hearing Yan's voice outside the room, Yayoi answered.

He took a turquoise Alchemical Daggers from a wooden box and examined it for a while, then put it back.

He looked around the lab and smiled with satisfaction.

Over the past year, his research had made a major breakthrough.

The five years of groundwork he'd laid earlier had also made this year especially productive.

First, he'd extended the Mirror Eye's usage time from ten minutes to half an hour.

He had successfully finished analyzing the Dragon Script of both the Wind King Eye and the Mirror Eye, and had even upgraded the Alchemy Sword.

He had also taken back Rin's two swords and reforged them for her. They were now sharp and light, imbued throughout with Wind Element.

The Gene Completion Plan had also succeeded, thanks to the Mirror Eye's constant analysis.

Working day and night, Yayoi had kept experimenting and exploring until he finally managed to turn the Uchiha Clan's unique gene sequence into Gene Fluid.

However, it wasn't yet the right time to use it, since his Dragon Blood hadn't gone out of control.

That was right. According to Yayoi's simulations,

injecting the Uchiha Gene Fluid during a certain period of Dragon Blood instability would allow the most perfect fusion of bloodlines.

Under the pressure of the Dragon Blood, the Uchiha Gene Fluid would fuse with the Divine Tree Bloodline on its own.

If nothing went wrong, he might even awaken the Sharingan.

The two bloodlines shared the same origin and had nearly identical genes. The only difference between the two clans was the unique gene sequence of the Uchiha.

As for the Senju—his own original bloodline—it also seemed to have a special gene sequence. Yayoi couldn't quite figure it out, but he guessed it might be a unique sequence that affected the body and chakra.

And he hadn't overlooked the Uzumaki, their distant relatives, either.

Earlier, he had taken Kushina's blood, and after studying it, he had discovered something.

Great clans like the Uzumaki, Senju, and Uchiha, which shared the same bloodline,

all had special sequences in their gene structures. This information was unlike that of ordinary ninja; they were special.

It gave Yayoi the feeling of being like a special kind of chakra.

Like a special gene sequence that transcribed information from chakra.
