Naruto: Starting with the Two Kamui

Lin Yu, who had been on edge for a month, finally felt relieved.

Orochimaru stepped forward and stood to Lin Yu's left and slightly behind, signifying that he respected Lin Yu above all others...

"So...that's how it is." After a moment's hesitation, Hiruzen Sarutobi said somberly.

"Yu-kun, spare his life for the sake of him being my teacher," Orochimaru said to Lin Yu.

Lin Yu sighed: "Orochimaru, the pioneer who killed his teacher, is actually pleading for his own teacher. It seems he didn't always want to destroy Konoha..."

"Considering your hard work and great contributions, I'll let him off the hook, but..." Lin Yu changed the subject.

"As for Kabuto, I have already dealt with him personally." Orochimaru seemed to know what Lin Yu wanted to say.

Lin Yu looked at A Fei, who nodded.

Lin Yu said, "Then there's no problem..."

The Third Hokage asked, "Orochimaru, I ask you, are the disappearances of people from villages around the Land of Fire, as well as the disappearances of ninjas from those villages, related to you?"

Orochimaru confessed, "Yeah, I did it all... I used to be so worried about being exposed, but now I don't have to worry anymore. You don't have the strength to deal with me, do you, Sensei?"

"Orochimaru, do you really not want to go back to the village? Even if I spare you your punishment." Hiruzen Sarutobi tried to persuade him.

"I want to get closer to the truth of this world. A village can never satisfy what I want, teacher..."

"Sigh..." Hiruzen Sarutobi recalled the moments he had taught Orochimaru, let out a long sigh, and closed his eyes.

"Lord Third Generation!!" the several secret service squad leaders exclaimed.

"Don't worry, he just fainted. If we take him back quickly and let Tsunade treat him, he might still be saved..." Orochimaru said.

Boom!

The gates of the outpost fell shut.

"Yu-kun, what are your thoughts on fighting the Third Hokage?" Orochimaru asked.

"Using him as a mirror to bid farewell to the past is just right. He makes me realize that this is the extent I am at this stage, and it's time to move on to the next stage." Lin Yu gazed into the distance.

"Then, Lord Yu, shall we proceed immediately?" Orochimaru inquired.

"That's right! I can't wait to obtain the true power of the First Hokage, Hashirama Senju!" Lin Yu's eyes blazed.

Orochimaru laughed and said, "Then, please follow me..."

The moment has finally arrived!

Chapter 35 At this moment, the transformation begins!

In a secret room deep within the underground base, Lin Yu sat upright, with Orochimaru, Tobi, and Uzuki Yuhi standing in front of him.

Orochimaru took out a glass tube filled with golden blood. Each drop was the culmination of Orochimaru's painstaking efforts. This small tube contained the path to a bright future for Lin Yu!

"Yu-kun, is there anything you'd like to know before we officially begin?" Orochimaru asked.

"How long will the whole process take?" Lin Yu asked.

"It varies from person to person, but for the vast majority of individuals, this process ends in less than a second. This is because the excessively powerful vitality of the Hashirama cells transforms into a deadly poison the moment they come into contact with the blood, causing the recipient to die instantly! But this is actually the most merciful ending, because the pain is only momentary."

"What if you don't die instantly?" Lin Yu asked.

"Hmph." Orochimaru chuckled wickedly, "If you don't die the moment it's injected, then congratulations, you will experience the pleasure of being worse than dead. In the next 60 seconds, the blood containing Hashirama's original cells will flow through your blood vessels as your blood circulates. Your blood will boil, it will truly boil, hotter than boiling water!"

"This will cause your blood pressure to spike, your blood vessels to rupture, and your body temperature to rise to unimaginable levels. All vital functions will cease, and you will be hovering between life and death—in layman's terms, a state of suspended animation."

"During the period of apparent death, your organs will gradually die due to lack of oxygen. Your heart, liver, spleen, lungs, and kidneys will all die without exception. The limit of apparent death is 15 minutes, which is also the limit of the brain's ability to withstand lack of oxygen. If you can wake up before your brain dies and control your chakra to guide the part of Hashirama's power that your body spontaneously merges to repair your organs, you can come back to life. Otherwise... you will sleep forever."

Lin Yu said, "So, if you don't wake up within 15 minutes, you'll die, right?"

"Hmph, that's exactly right."

"What are the conditions for waking up?" Lin Yu asked.

Orochimaru shrugged and said, "Well, I don't know, because my current research is limited to the physical body and hasn't yet touched on the spiritual realm. My experience in this area is still blank..."

"So, if one wakes up before the brain dies and guides Hashirama's power to repair the organs, does that mean it was a success?" Lin Yu asked.

"No~" Orochimaru shook his finger and said, "Then it can only mean that you are qualified to formally receive the baptism of this power. The next 24 hours are the real beginning. Hashirama's cells will divide and proliferate uncontrollably in your body and gradually replace your own cells. To put it bluntly, it is the process of Hashirama's cells turning against your body."

"At this time, the interstitial cells are equivalent to 'cancer cells'. We name this type of cancer 'interstitial carcinoma'. Interstitial carcinoma is different from any other type of cancer. Its onset cycle is only 24 hours. Whether a person lives or dies is determined within these 24 hours."

"Then what standard defines life and death?" asked Uzuki Sunset.

"Good question, young lady~ Let's take disease as an example. When a disease erodes the body, the body will also produce 'antibodies'. Hashirama cancer is no exception. The body's cells will gradually produce 'antibodies' against the Hashirama cells. With antibodies, there is tolerance."

"These 24 hours are a test, to see if Yu-jun's own cells will be killed and extinct by Hashirama cells first, or if Yu-jun can produce enough antibodies. In short, we'll know the answer in 24 hours. Of course, this process is also accompanied by unimaginable pain; every cell in his body is screaming in agony..."

"Gulp." Uzuki Yuhi swallowed hard, looking at Lin Yu with a complicated and puzzled expression.

Lin Yu remained calm and composed, saying, "Go on."

"If you successfully survive 24 hours, congratulations, you've already succeeded halfway~ But interstitial cells are the strongest cells. Even with antibodies, they can never be killed by your own cells. They will continue to proliferate and divide in your body, but your own cells will no longer be easily killed."

"Interstitial cells and your own cells coexist in your body and tend to reach a certain balance over time, which leads to two outcomes... one is assimilation, and the other is fusion."

"What's the difference between assimilation and integration?" Lin Yu knew that the real key had arrived.

"Assimilation. The Hashirama cells will actively degrade to adapt to your own cells, and your own cells will also undergo a certain degree of optimization to adapt to the Hashirama cells. One decreases and the other increases, and after taking an average value and stabilizing, you will obtain a semi-finished Hashirama body. Well, although it is a semi-finished product, it is still much stronger than what you have now..."

"What about fusion?"

"Hmph hmph hmph hmph..." Orochimaru revealed a fanatical smile: "The Hashirama cells will fuse with your own cells, truly and completely becoming a part of you, Uchiha Yu, no longer separate from each other. You will obtain the complete Hashirama body!"

Lin Yu clenched his fist and said, "That goes without saying, it's definitely fused. If it's not fused, I'd rather die!"

Orochimaru looked at Lin Yu with admiration, finding him more and more pleasing to the eye. He smiled and said, "Not bad, Yu-kun~ Although I have high hopes for you, given the great risks, just in case, it would be better if you made some arrangements for your affairs after death. What do you think, Yu-kun?"

Lin Yu nodded.

Orochimaru smiled knowingly, then discreetly excused himself and left the room.

Lin Yu looked at A Fei, thinking that he had been in the Naruto world for more than half a year, and A Fei was the only person he could truly call a friend...

Although Afei is not a human being in the true sense of the word, and although Afei has some quirks that Lin Yu cannot agree with, he has been with Lin Yu through thick and thin and is an irreplaceable best friend!

"Ah Fei, we're all so familiar now, I won't say anything too mushy. Thank you for taking care of me these past few days. If it were me..."

"No, no, no, I won't be sad if you die."

"Uh, you're being way too direct..."

"But it's more interesting when you're alive! Let me tell you a secret: Hashirama Senju himself needs to eat and poop!"

"How did you know??" Lin Yu asked in surprise.

Afei leaned close to Lin Yu's ear and whispered, "This is what Ban said in a dream when he was alive!"

"You rascal..." Lin Yu shook his head, both amused and exasperated.

Afei turned and walked away, thinking to himself: Yu, if you really die, one day I will have Nagato revive you with the Samsara Rebirth Technique, because life without you will definitely become boring!

Only Lin Yu and Maoyue Xiyang remained in the room.

“Waaah…” Uzuki Yuhi started crying.

"Oh dear, why are you crying?" Lin Yu rarely showed tenderness when he thought of the possibility of a life-or-death separation.

“You won’t die, right? Although I don’t understand why you’re so strong, you still have to take this risk and pay this price to become stronger, even if I say I don’t want you to take that risk, you won’t listen, right?” Uzuki Yuu looked at Lin Yu with a pitiful expression.

"I'm glad you shed tears for me, Sunset, if I'm gone, I hope you..."

"I don't want you to leave!" Uzuki Yuhi suddenly became agitated: "You promised me a hot spring, but it hasn't been built yet! You can't just leave like this!"

"Oh my, you really like soaking in hot springs that much?" Lin Yu asked.

"Do you know what it feels like for a girl to not be able to take a hot shower for a month? Baka, baka!" Uzuki Yuhi stepped forward and hugged Lin Yu.

"When the hot spring is built, can I bathe with you?" Lin Yu's hand was pressed against Maoyue Xiyang's cheek.

As the sun set in Maoyue, her watery eyes gazed at Lin Yu and she asked in return, "Are you satisfied just because we shower together?"

"Then what else needs to be done?" Lin Yu asked in surprise.

"Let's do what we didn't finish last time. This time... it's not for Konoha Village, it's something I'm doing willingly!" Uzuki Yuhi said affectionately.

"Then, have another child for me?" Lin Yu said with a smile.

"Ah, this, this... I'm only 17 years old this year, I'm still too young, how about, how about in a couple of years?" Uzuki Yuhi bit her red lips, her face as red as if it were about to bleed.

"Oh my, I didn't know you could make such a cute expression," Lin Yu said with a smile.

"So promise me, don't die, okay?" Uzuki Yuhi said earnestly.

"Okay, I promise you." Lin Yu nodded solemnly.

Also, before leaving, Uzuki Yuhi took the initiative to kiss Lin Yu's lips.

Five minutes later, Orochimaru walked in.

"Are you ready, Yu-jun?"

"Let's begin. Life and death are in the hands of fate, and wealth and honor are determined by heaven!" Lin Yu stretched out his arm.

The glass tube containing golden blood had a tiny syringe popped out from the end, but not a single drop flowed out, because every drop was extremely precious and no waste was allowed!

"Hoo..." Orochimaru steadied himself, located the vein, inserted the needle, took a deep breath, pushed the syringe down, and injected the concentrated blood containing Hashirama's perfect original cells into Lin Yu's body!

Begin your transformation now!

Chapter 36: Boiling Point, Sublimation, Transcending Oneself!

In the first second, nothing happened, and Lin Yu showed no discomfort. On the contrary, he felt extremely happy, because besides death, there was a more sublime and bright future waiting for him.

Looking at Lin Yu like this, Orochimaru thought: This is only natural. The right half of Yu-kun's body was transplanted with a Hashirama artificial body, which means that the power of the First Hokage does not reject this young body of Uchiha Obito. The problem is, the 'soul' belonging to 'Yu' residing in 'Obito's' body, hovering between life and death, can it withstand the unknown test...

As expected of Orochimaru, he actually managed to perceive the truth about the existence of 'Uchiha Yu' from a limited perspective, based on his knowledge!

In the next minute, the stem cells injected into Lin Yu's blood vessels dispersed throughout his body's blood vessels as the blood circulated, causing his blood to boil, his blood pressure to surge, and his blood vessels to rupture!

Thump! With a heartbeat as heavy as a hammer blow, Lin Yu's eyes suddenly widened!

"Ah ...

"Yu!!!" Hearing the scream in the corridor, Uzuki Yuhi rushed into the room without thinking, but Uzumaki Zetsu Tobi held her shoulder and shook his head at her...
