Ke Xue: He mastered the steel-cutting divine skill at the start.

In his heart, he felt happy for Haibara: "What a pitiful little girl. She only has Miyazaki-nii-san as family now. I seem to be a little luckier than her. I will have a playmate in the future. This seems like a lot of fun."

In the study.

Miyazaki Yu and Haibara Ai stared at each other, their eyes wide open.

"Didn't I tell you to stay in the Swordmaster's territory? Why are you looking for me?"

Ai Haibara wrinkled her nose slightly and snorted.

“You just leave my sister and me there and don’t care. My sister and I are just sitting there doing nothing all day. We can’t stand it. After all, we are human beings, not flowers and plants that can grow forever just by watering and fertilizing us.”

Upon hearing this, Miyazaki Yu couldn't help but touch his nose.

He has been extremely busy lately, especially recently he has been engrossed in researching mental power, putting almost all his energy into it and neglecting everything else.

Therefore, communication with the two girls was neglected.

The two sisters had been staying in the Sword Master's territory for a long time, and they were quite lonely.

Seeing his expression, Ai Haibara relaxed a little; this guy still cared about them.

However, her expression immediately turned serious.

"And the reason I came to find you is because I discovered your secret. You and that Dr. Asai are secretly researching APTX-4869, aren't you?"

Before he finished speaking, Miyazaki Yu raised his head and his gaze instantly sharpened.

In just a moment, that intense gaze made the little girl's heart flutter, and her heart couldn't help but pound wildly, as if facing a prehistoric beast, with a huge stone pressing on her heart.

"you,,,,"

A familiar sense of dread washed over her; she knew this feeling all too well. It was the intense oppression that only the most terrifying figures in the Black Organization could bring.

No, compared to this terrifying aura that felt almost tangible, the aura of those guys was as weak and powerless as an infant.

The contraction of my heart seemed to be substantially affected by the other person's aura, because the body's instinctive fear exceeded the scope of what reason could regulate!

However, a moment later, Miyazaki Yu suddenly smiled, and his terrifying aura vanished like the tide.

Ai Haibara immediately began to gasp for breath, just like someone who had been rescued from drowning. The sweet air flowing back into her lungs made her feel as if she had come back to life.

"I'm sorry, I've recently made a breakthrough in my strength. I only meant to glare at you, but it ended up causing harm."

As she spoke, she quickly and gently patted the little girl's back. Ai Haibara's lips trembled, and tears instantly streamed down her face.

"You were just trying to kill me, weren't you? You bad person!"

Miyazaki Yu felt a headache coming on. He had originally wanted to intimidate this cunning little girl, but now he was suddenly at a loss.

But since he had made a mistake, all he could do now was smile wryly and let the little girl cry.

Chapter 256 The Path to Immortality (3rd update)

Ai Haibara hadn't expected that what was originally just a momentary feeling of being wronged would lead her to cry uncontrollably.

Who knew that once she started crying, she couldn't stop and burst into tears. Miyazaki Yu could only stay with her until she finally stopped after half an hour.

Miyazaki Yu also knew that Ai Haibara had never truly escaped the shadow of the Black Organization; her heart remained sensitive and repressed.

Human nature is like a spring; if it is constantly suppressed, the force of the rebound will be terrifying once it has the opportunity to bounce back.

And that's exactly what Ai Haibara was like at that moment.

She is actually a very mischievous and somewhat cunning girl. If she had grown up under normal circumstances, she would definitely have been a very arrogant young lady or princess, perhaps even with a sharp tongue and a penchant for teasing people.

However, within the Black Organization, she was used as an outstanding researcher at a young age, in order to protect herself and, incidentally, her older sister.

She built a thick protective shell around her heart.

This protective shell is also her disguise to protect herself; it is her defense line.

But this guy in front of them gave them hope, led them away from the clutches of the organization, and appeared before them like a divine intervention when they were in their most perilous moment.

Like a god, he crushed all his enemies.

From that moment on, the seed of Miyazaki Yu was planted in the girl's heart, and it seemed that she would feel more at ease when she was by his side.

That's why she's been staying at Miyazaki Yu's base for a while now, which is why she can't stand it anymore. Especially now that she's a child again, she doesn't have to worry about being hunted down by the organization as long as she's careful. That's why she left the Sword Master's Territory, which is almost an absolutely safe area.

"Alright, alright, you're not a real child anymore, so stop crying like that."

He wasn't very good at coaxing girls, and among the women he knew, Xiaolan seemed weak but was actually strong and determined, while Sonoko was well-behaved and sensible. She would sometimes act cute and charming, but she would never cry easily.

As for Morita Ouran, she is a strong woman. This girl is very rational and never easily shows her emotions.

As for Vermouth, there's no need to even think about it. She has a queen-like presence and an intimidating aura. She would never have a moment like this, with tears streaming down her face. Perhaps she does, but she would never let anyone see her vulnerable side.

Now, Ai Haibara is like a hedgehog that has laid down its quills, letting down all its guard around Miyazaki Hayao and revealing its vulnerable side.

"Hmph, wasn't someone just acting all powerful a moment ago? A great swordsman, actually being mean to a little girl. If word gets out, you'll definitely be condemned!"

Miyazaki Yu reached out and patted the little girl's head, smiling slightly. "Although I didn't intend to keep it from you when I left you there, I knew you would find out sooner or later. I was also researching that drug, but I was still a little surprised to hear you say it now, which is why I accidentally revealed my aura."

Ai Haibara angrily shook off his large hand.

"I'm an eighteen-year-old adult, and you're only seventeen. You're a year younger than me, so you should call me 'older sister'!"

Looking at the little girl who looked like an angry hamster, Miyazaki Yu couldn't help but laugh.

"But you're just a little sister, only in first grade, right? How can someone at that level expect me to call you 'older sister'?"

Miyazaki Yu deliberately joked and laughed with her for a while, and the atmosphere finally returned to normal.

After a while, Ai Haibara gradually became serious, her little face full of solemnity.

"I saw the document in Dr. Asai's hand. Although it was filled with a lot of information, I could still tell that it was the same document that I used to carry with me. In other words, you have known some things since then."

She made no attempt to conceal her true intentions; she went straight to the point.

Miyazaki Yu also made no attempt to evade the question, and slowly nodded.

"You're right, I noticed that document from that time on!"

So Miyazaki Yu began to explain the cause and effect, but what Miyazaki Yu said was also after careful consideration.

In his story, he accidentally saw this document, discovered its value, and secretly used his memory to memorize the entire document.

After carefully reviewing the information, a bold idea emerged.

"As the developer of this drug, you are certainly aware of its value. Rejuvenation may only be one of its potential benefits, but it is already enough to drive people crazy. However, this is not all. What is truly terrifying is the real effect of this drug!"

Ai Haibara frowned and uttered two words in a serious tone.

"eternal life!"

After uttering those two words, both of them fell silent.

These two words represent the lifelong pursuit of countless emperors and generals throughout history, the ultimate path sought by countless people, and the most fundamental desire of all!

The so-called desires of wine, women, wealth, and power become trivial matters in the face of immortality.

Because whatever kind of enjoyment it is, or anything else, is just a branch attached to the main trunk of immortality!

Just like emperors and generals, they all yearn for immortality, for the ability to live forever, to enjoy power and all that is good!

Even for ordinary people, if they had endless life, all the things they once longed for but could not obtain might be within their grasp.

"Yes, it's immortality. You probably already know that I was ambushed and remained unconscious for a whole year. But what you don't know is that during that year, my body couldn't move, but my mind was active. Do you know what that feels like?"

The girl's heart skipped a beat, and she shuddered involuntarily. Then she looked at the young man in front of her with an incredulous gaze.

"You actually went through something like this? It's terrifying. It's probably the most horrible punishment in the world."

Miyazaki Yu nodded, agreeing with this statement.

If there were no world of consciousness, Miyazaki Yu could study swordsmanship within it, but as he said, his mind would always be clear, but his body would be unable to move, and this would last for a very long time.

This kind of punishment is like being locked in a dark room with no chance of release!

Intense loneliness can feel like a sharp blade, repeatedly cutting into one's own vulnerable heart.

One can imagine that if one had the choice to die in that situation, 99 percent of people probably wouldn't have lived for more than a month; it would have been an extreme ordeal.

A hint of pity crept into Ai Haibara's eyes.

"I never imagined he had gone through something like this; it's truly unbelievable!"

Miyazaki Yu said in a deep voice, "It was an extreme kind of loneliness. I could hear and feel clearly, but I just couldn't respond at all. At that time, I was very grateful for the care of Ran and Aunt Meihui. If it weren't for them, I might have gone crazy."

The only way I can pass the time is to mentally simulate the variations of swordsmanship, the different ways of applying force, and various combat scenarios.

Ai Haibara suddenly realized, "No wonder he was able to cultivate his swordsmanship to such a level. Perhaps it is this extreme loneliness that gave him absolute sharpness, making his sword indestructible!"

And wasn't his obsession with immortality planted at that time?

Thinking of this, I couldn't help but breathe a sigh of relief.

Chapter 257 New Family Member

This is the script that Miyazaki Hayao created for himself.

That was a young man who, by accident, had experienced the cruelest thing, and developed an obsession with survival and living.

Although a little trickery was used to deceive a pure-hearted girl, there was nothing that could be done.

He couldn't very well tell Ai Haibara that he was actually a time traveler.

So this can be considered a white lie.

Moreover, Ai Haibara, due to the previous accident, also took that drug and is now following the same path as in the original story.

Even if he didn't ask, the other party still needs to continue researching this drug; she can't stay a little girl forever.

So at this point, she needed a reason to convince herself, after all, this girl was still very kind at heart. She actually strongly resisted making this kind of drug. If it weren't for the coercion of the Black Organization, she would never have made such a thing.

"I never expected that this seemingly incredibly strong man would also have a vulnerable side."

Thinking of this, as if he had discovered something extraordinary, a smile appeared on his face as the corners of his mouth curled up.

"I understand. Don't worry, I will continue to research this drug. After all, even if it's not for you, but just for myself, I need to find a way to restore my body. I can't stay in the state of a primary school student forever. However..."

She looked up and stared directly into Miyazaki Yu's eyes.

“I don’t want to stay at your base any longer. Although it’s safe there, I’m just too lonely. Even with my sister by my side, I can’t stand it. So I ask to stay at your home. I’ll go back if I need to use the equipment at the base.”
