Self-Sacrificing Experiment

Might Guy grew nervous. Had Naruto discovered something? Or had Rock Lee told him?

Naruto! The Eight Inner Gates required burning one's life force to obtain immense power. Since Naruto's future potential was even higher than Rock Lee's, he had chosen Rock Lee instead of him.

At this moment, there were no outsiders present.

Naruto trusted everyone here.

There were some secrets he could share.

"Guy-sensei, please don't be surprised. It was due to certain circumstances that I specifically pursued you, insisting that you take me as your disciple."

"Guy-sensei is a responsible man, and I don't want to hide this any longer. Yes, I actually know the Eight Inner Gates."

"Ah!" Rock Lee hurriedly shook his head; he hadn't leaked a single bit of information about the Eight Inner Gates.

"Ah!" Might Guy thought, How many years has it been since my father passed away? It's impossible for him to have taught Naruto in a dream!

Naruto requested a drink, then opened the third gate, the Gate of Life. A massive wave of chakra surged and rolled in layers across Naruto's skin.

Neji was shocked; he clearly felt the true gap between himself and Naruto.

Rock Lee shouted, "Naruto is truly the man I admire! I will chase after him with all my might!"

Might Guy looked thoughtful.

"Please, Guy-sensei, open the Eight Inner Gates. Hinata and Neji, please observe carefully the difference in chakra flow between me and Guy-sensei when we open the gates. I need to make some comparisons," Naruto said loudly.

Might Guy gave a thumbs up: "Naruto, you are truly a taijutsu genius. I am willing to pave a broader future for your path in taijutsu."

Might Guy opened them step by step.

Gate of Opening, Gate of Healing, Gate of Life, Gate of Pain, Gate of Limit, Gate of View.

Opening the last two gates required chakra to flow through only one channel, so there was no point in comparing them.

Hinata, being meticulous, quickly drew diagrams of Naruto's chakra flow and Might Guy's chakra flow on paper.

"Guy-sensei, please stop immediately. I can see you are about to sustain damage," Naruto said, having gained some understanding.

Might Guy smiled knowingly: "Naruto, please teach me."

Might Guy also saw that Naruto's method of opening the gates placed less burden on the body; it seemed there was no damage at all. If one could truly open all the Eight Inner Gates without damaging their life force, even while obtaining power dozens of times greater than a Kage, that would be the truly perfected Eight Inner Gates.

Naruto carefully observed the chakra comparison diagrams drawn by Hinata and Neji.

Earlier, Naruto had already studied the human meridian system and its relationship with each gate.

"Guy-sensei, Rock Lee, let me explain my understanding to you."

"The power generated after Guy-sensei opens the Gate of Life is several times stronger than mine because the chakra flow is shorter and faster."

"However, my method does not harm the body; it only accelerates the consumption of chakra within the body. Once the chakra is nearly exhausted, it will automatically end."

"So, I can combine the two to find a flow pattern for opening the gates that has basically no damage but higher power. I will first test a better method for the first three gates."

Might Guy stopped Naruto: "Let me do it, teacher. The experiments will damage the body."

Naruto smiled and said: "Guy-sensei, you don't need to worry. I know my own body. Although I know you have more experience with the Eight Inner Gates and a higher physical limit, I feel my recovery ability might be better than yours."

Might Guy suddenly realized: Naruto was, after all, the son of Kushina Uzumaki.

First gate, Gate of Opening.

One meridian.

Gate of Opening to Gate of Healing, six meridians.

Gate of Healing to Gate of Life, five meridians.

Gate of Life to Gate of Pain, four meridians.

Gate of Pain to Gate of Limit, three meridians.

Gate of Limit to Gate of View, two meridians.

Naruto's physical limit allowed him to open the Gate of Life; the following three gates would require long-term extreme training to open. To completely perfect the Eight Inner Gates, Naruto would need to experiment 720 times to reach the sixth gate.

By comparing the results of these 720 attempts, he could select the most perfect one to achieve the final result.

Naruto became obsessed with the process of experimenting with the Eight Inner Gates. Every time, he had a new experience, as if he had gained a deeper understanding of his own body.

Hinata watched as Naruto's chakra became chaotic due to incorrect openings, causing him to vomit blood as it surged within his body. Her heart ached, and she shed tears, but she stubbornly insisted on staying by Naruto's side.

Might Guy did not leave either.

Rock Lee and Neji engaged in frantic sparring.

The night deepened, the moon cast a faint light, and not a single star could be seen.

In the small woods, insects chirped everywhere.

Naruto let out a long roar toward the sky: "I found it! The best way to open the first three gates of the Eight Inner Gates. Guy-sensei, my method is correct. Opening them this way allows one to obtain powerful strength without causing damage to the body."

Might Guy's eyes turned red. A man does not easily shed tears, but Naruto's resilience and wisdom made Might Guy weep.

Rock Lee also wept bitterly.

"Perhaps, Naruto will become a legend of taijutsu in the ninja world," Might Guy envisioned.

With his spirit and energy spent, Naruto felt a fatigue as heavy as a mountain and collapsed into a deep sleep.

Notification.

Mission complete, sharing permissions unlocked.

Naruto slept at home for five days, during which he polished off the food in the refrigerator three times.

Might Guy personally explained the situation to Minato Namikaze and Kushina Uzumaki.

The two looked at Naruto, unable to find the words to describe their feelings.

Their child had seemingly become incredibly powerful without them even noticing.

Hadn't Naruto just started at the Ninja Academy?

Minato Namikaze, broad-minded as he was, believed this wasn't a bad thing, for only the strong could stand firm.

Five days later, Naruto was full of vigor, his exhaustion swept away, and the total amount of chakra within him had grown significantly once more.

Hard work pays off, but I revealed some secrets to everyone this time. Mom and Dad definitely know now; I wonder what they're thinking. Naruto stepped out of his room.

Kushina Uzumaki was boiling water. Seeing Naruto looking refreshed, she smiled and said, "Naruto, when will you surpass your father? Don't keep secrets from Mom anymore."

Naruto felt that nothing had changed; no matter how powerful he became in the future, in his parents' eyes, he would always be a child in need of protection.

Minato Namikaze's most formidable skill seemed to be the Flying Thunder God, a space-time ninjutsu invented by the Second Hokage. Under the system's unique effects, was the Flying Thunder God still useful?

Naruto suddenly wondered.

Useless. Locked by the host. The only method of distance movement is the Body Flicker Technique performed by the host using chakra, which the host can use to catch enemies off guard.

"Melon-Skin System, this is the first time I've found you so cute."

Thank you for the five-star review, host.

Naruto opened the refrigerator, which was stocked with cooked food and cold dishes: "Mom, did the school help me take leave?"

Kushina Uzumaki poured some water: "I left that to your father."

"Does Dad have time? The Hokage Office is so busy, he might forget." Naruto felt it wasn't very reliable.

At the Hokage Office, Minato Namikaze suddenly stopped reviewing documents, thinking there was something very important he hadn't done yet.

On the Ninja Academy bulletin board.

First truant: Uzumaki Naruto!
