Staying up late is bad, I recommend pulling an all-nighter

"Strange, the Hyuga Clan's bloodline shares a slight similarity with my blood, and even with the Uchiha's blood.

However, it will still largely devour the Hyuga Clan's cells, with only a negligible portion being assimilated."

In the busy laboratory, four figures were engrossed in their work.

They were Yayoi's Shadow Clones, conducting daily observations and extractions of the Uchiha Gene.

One clone was still conducting experiments on the erosion of living beings by dragon blood.

White mice, even squirrels, and white rabbits.

But the usual outcome was a vague mess of flesh and blood.

Yayoi's main body was observing the Hyuga Clan's cells under a microscope.

He recorded the experimental data from the Hyuga blood experiments, and also created another Shadow Clone to research the Hyuga Clan's experiments.

He didn't place much importance on this, as even if the Hyuga bloodline was excellent, it would be useless if it couldn't complement his own.

The reason for researching the Hyuga bloodline was still due to the Caged Bird.

Yayoi was very curious about it, wondering what kind of curse mark could be so hated.

In the story, this terrible curse mark was even branded onto their souls after death.

Even death couldn't stop the Caged Bird; it was too terrifying.

This was a dual curse mark branded onto both the body and soul.

If he could understand this, perhaps he could obtain a method of control that penetrated the soul.

The experiments concluded, leaving a few Shadow Clones to tidy up the laboratory.

Yayoi left the former bedroom and walked into the living room.

A large sun slowly rose on the horizon, and a ray of early morning sunlight slanted across Yayoi's face.

"It's dawn. Another all-nighter."

Yayoi yawned, he was almost forgetting what a normal sleep schedule was.

"This research took too long."

Last night, driven by his thirst for knowledge, and because Rin had sent the materials too late, Yayoi decided to pull an all-nighter. He planned to sleep at school.

After all, classroom learning was boring, and it was better to replenish his mental energy.

However, he needed to fill his stomach first.

He took instant noodles out of the refrigerator, boiled water, and added beef and chicken legs.

Ten minutes later, looking at the steaming, fully-loaded instant noodles, Miyoshi's appetite was whetted.

After finishing the instant noodles, he ate another large bag of beef, and Miyoshi was finally full.

At this moment, the Shadow Clone dispelled, and fatigue began to accumulate.

Miyoshi collapsed directly onto the table, motionless, as if he had completely fallen asleep.

"Miyoshi-kun, it's time for school!"

"Hurry up, or you'll be late."

Outside, Yan's crisp voice rang out.

"It's time for school. Forget it, I'm not going. It's all the same anyway. At worst, I'll ask Teacher Utsugi for leave tomorrow. Yes, that's it."

In a state of extreme fatigue, Miyoshi successfully convinced himself.

Three minutes later.

Yan's shouting voice abruptly stopped. Suddenly, a purple-haired figure gracefully landed on the windowsill, her small frame poised.

Seeing Miyoshi sprawled on the table in the living room, fast asleep, Yan knew what was going on.

She opened the window and tiptoed in, seemingly afraid of waking Miyoshi.

Miyoshi, however, instinctively sensed someone's presence, his ears twitching slightly.

But perhaps because he was used to it, Yan sensed the familiar Chakra. His ears only twitched once before he fell back asleep.

"So cautious, Miyoshi-kun."

The sharp Yan sensed a momentary anomaly.

"Today, you must have stayed up late again."

Looking at the empty instant noodle box, Yan immediately understood everything.

Only when he stayed up all night would Miyoshi eat instant noodles to save time.

Otherwise, Miyoshi, who usually had plenty of time, would never be so perfunctory.

"This is so troublesome. When you wake up, I'm definitely going to have a good talk with you."

Yan seemed to be talking to herself, but her hands were not idle.

She picked up the instant noodle box and threw it into the trash can, tidying up the slightly messy living room as she went.

"Sleeping here will catch a cold."

Yan playfully smoothed Miyoshi's perked-up hair, then scooped him up in a princess carry.

They walked through the hallway and soon arrived at a bedroom.

Opening the bedroom door, they found it very simple, with only a bed and a desk.

Yan placed Miyoshi on the bed, carefully tucked him in, and then quietly left.

She was going to school; otherwise, no one would request leave for Miyoshi.

As she was leaving, Yan also took the household trash bag with her.

"Why are you alone?"

In the morning, Rin, sitting at her seat with her chin in her hand, asked Yan suspiciously as she walked into the classroom alone.

"Where is Uesugi Yayoi?"

"Miyoshi-kun isn't feeling well and requested leave."

Yan smiled gently, sat down at her seat, and tidied her books.

"He's actually not feeling well?"

Rin said doubtfully, feeling like she'd heard a joke.

Could a Senju get sick?

She had seen Miyoshi full of life just last night, and now he was suddenly unwell?

However, she didn't voice this thought to Yan, only complaining internally.

Their relationship wasn't yet at the stage where they could casually complain to each other.

"Mhm."

"Even the First Hokage gets sick sometimes."

Yan simply gave an example, which effectively silenced Rin's retort.

It seemed that way.

But what was wrong with this guy?

She had just obtained her blood last night, and now he suddenly requested sick leave.

Could it be that he stayed up late last night doing his so-called experiments?

How could that be?

As she thought, Rin shook her delicate little face to herself.

"However, you can't be in trouble, not until you unlock my Caged Bird."

"Holy crap!"

Yayoi groggily opened his eyes and then saw the evening glow outside the window.

The crimson clouds were like little birds, lazily swaying in the sky, the sun hidden by the mist.

"I'm doomed!"

Yayoi froze for three seconds, then his eyes snapped open, and he sat up with a whoosh.

"Damn it, I skipped class. I hope Teacher Utsugi says less to me tomorrow."

Realizing he was completely late, Yayoi stopped panicking.

He closed his eyes and completely gave up, flopping back down with a thud.

"At this time, school should be over."

Yayoi closed his eyes to rest, silently calculating the current time in his mind.

He hadn't expected the fatigue value from this Shadow Clone to be more severe than he'd imagined.

To the point that he had fallen fast asleep in broad daylight immediately after dispelling the Shadow Clone.

"But, I remember I fell asleep in the living room last. Why am I in the bedroom when I woke up?"

"Something's not right."

Yayoi thought about it and still felt uneasy. Adjusting his state, he got up to check his laboratory.

His laboratory was set up in his parents' original master bedroom. To prevent anyone from accidentally entering, Yayoi had specially sealed it off. A password was required to trigger the mechanism and open it.

He entered the password and carefully checked, finding no signs of anyone else.

Then, Yayoi returned to the living room and found it completely renovated.

The instant noodle containers he had eaten were gone, the messy areas had been tidied up, and even the trash bag had been replaced with a new one.
