Gene Information

"The thing's function was simple enough: a one-time repulsion.

But it would send its user flying, since it was only an incomplete item."

Once Yayoi had deciphered the Dragon Script, he understood what it did.

It simply released a repulsive force. It wasn't very powerful, so it really was useless to Yayoi.

Still, if he encountered some sudden explosion, it might save someone's life.

"It really is neither useful nor worth throwing away."

Yayoi casually tossed it onto the workbench.

It was useless and ugly, so he might as well give it to Shengshu later.

In the original story, Shengshu had died. Yayoi had forgotten which war it was, but he seemed to have died a pretty pathetic death.

The next time they met, he would give him this ugly thing.

Maybe it could even save his life. That would be a fitting gesture between friends.

"Nothing on the agenda today. I'll keep researching."

Yayoi shook his head, feeling that he had wasted two days.

"Maybe I can get Yan to help with my research at noon. No, forget it."

Yayoi was practically only on the school's books now. He was hardly ever seen there.

Since he had contributed so much at the hospital, he was basically employed there.

Normally, Yayoi sent out a Shadow Clone to clock in.

As for the school, he had already spoken with Teacher Utsugi.

Every term, he went to Teacher Utsugi to take the required assessments for his classes.

As for how he had gotten Teacher Utsugi to agree, it was, of course, because Yayoi's burning Will of Fire could no longer be concealed.

"Now, what should I research next?"

Yayoi idly fiddled with a test tube.

"Another day, I should ask old man Enichi to bring me a piece of Chakra Conductive Metal. He wouldn't be stingy about letting me make a weapon for his granddaughter, would he?"

"As for Rin, learning more swordsmanship might do her good, but I don't have the time.

Maybe I should just have Yan teach her. Yan would probably agree."

Time always flew by, leaving people full of regret.

Konoha, Year 34

The war continued, growing ever fiercer.

Even other countries began joining in, and the pressure on Konoha grew heavier and heavier.

They had even started resorting to "cheating" by recruiting sixth-year students. Luckily, Yayoi was in his fifth year.

But even if he were drafted, he didn't need to worry. He was technically a medical practitioner.

As for Yan, old man Enichi would naturally look out for her. And as for Rin, there was no way Yayoi would believe she had no background when she'd reached this age without the Caged Bird seal being placed on her.

They would officially become Genin after graduating from sixth grade, and would simply complete their six years of schooling as usual.

Yayoi continued spending his days leisurely conducting experiments.

But thanks to Yan's cooperation and the progress of his research, his study of Uchiha genes was finally beginning to make headway.

The Uchiha genes contained a special sequence, one that held a unique kind of information.

The reason he called it special was that it was extremely dormant.

It was recessive—or rather, it only appeared in the genes of Uchiha who had awakened the Sharingan.

It wasn't incomplete, but whole. Everyone was born with it.

This special gene sequence was well hidden. If Yayoi hadn't studied Uchiha genes so extensively, he might never have discovered it.

His research showed that this information was noticeably more active in Yan's genes.

In the blood of other Uchiha who had awakened the Sharingan, the special gene sequence seemed much more dormant.

Yayoi made a bold guess.

This might be the key to awakening the Sharingan.

The Sharingan awakened because intense emotional fluctuations caused an Uchiha's brain to produce a special kind of chakra.

When that chakra acted on the eyes, the result was a pair of blood-red irises.

The special chakra responsible for awakening the Sharingan might be determined by this gene sequence.

As he continued investigating this possibility, Yayoi barely even had time for his daily Dragon Script translations.

He devoted himself completely to studying this special gene sequence.

He took out all the Uchiha cell samples and, after a month of research, finally unlocked the Uchiha secret.

Just as he'd suspected, Yayoi's hypothesis had been confirmed.

The Uchiha clan members carried a special gene sequence in their bodies, but it was extremely dormant. It took intense emotional fluctuations and mental stimulation to activate it.

This was the Uchiha's power, the foundation of their clan's strength.

The so-called prodigies—or someone like Yan, who awakened the Sharingan at the slightest emotional disturbance—might have naturally active gene sequences. That meant even a slight shift in emotion could stimulate this special gene sequence.

And what that looked like from the outside was the awakening of the Sharingan!

Blood-red eyes, a special gene sequence—these were the key.

A complete key.

He understood. Yayoi understood.

The secret of the Uchiha Sharingan lay in this special gene sequence.

As long as he could fully fuse with this gene sequence, Yayoi could obtain the Uchiha Bloodline.

And given the compatibility between Yayoi's Senju Gene and Uchiha genes, such a fusion wasn't inconceivable. In fact, it would be exceptionally easy.

If his Dragon Clan bloodline went into a frenzy then, the bloodline suppression might even let Yayoi perfectly fuse with the Uchiha Bloodline in a short time.

He wouldn't even need to go through an adaptation period.

Never underestimate the power of genes. To survive, they could give up anything.

After making this discovery, Yayoi devoted all his energy to studying and extracting the Uchiha special gene sequence.

It wasn't a particularly simple process. It would take time.

Yayoi needed to extract the gene sequence intact.

Throughout this process, he still had breakfast with Yan every day and discussed sword-dance ideas with Rin.

Whenever he returned to the lab, Yayoi would shed every distraction and focus completely on studying the gene sequence, leaving only a trace of caution in case someone followed him.

The discovery of the Uchiha gene sequence showed him a way to advance rapidly.

Yayoi's plan was simple.

First, he had to enter Blood Rage—a complete Blood Rage.

Although his bloodline had been diluted, returning to its source would be easier than taking it step by step.

He only had to maintain a balance between the two.

Once Yayoi entered the complete Fourth Bloody Surge, the Dragon Blood in his body would be strengthened like never before.

By then, his Dragon Blood would boil and his bloodline would be purified. His Dragon bloodline would also suppress the Divine Tree Bloodline for a short time.

If he injected the Uchiha gene sequence at that moment, the Dragon Blood's pressure would force the Uchiha genes to merge with the Senju genes.

Once the Divine Tree Bloodline was made whole, it would become vastly stronger.

Since the Divine Tree Bloodline needed time to grow, the Dragon Blood would continue to suppress it, but the two would at least maintain a brief balance.

During that time, with his restored bloodline and Blood Rage's ability to stimulate it, Yayoi would be able to activate this gene sequence with ease.

Once the so-called Sharingan awakened, his Divine Tree Bloodline would instantly restore the balance.
