Byakugan and Uchiha Mikoto

At the first light of dawn, a pale golden ray of sunlight slipped through the gaps in the paper window and cast long streaks of light across the floor.

Uchiha Sanpo had long since awakened. His eyes were closed, but his consciousness was immersed in the system interface that only he could see.

Basic Uzumaki Sage Body (475/500)

"Only 25 experience points left."

Uchiha Sanpo opened his eyes, his Three-Tomoe Sharingan glinting dark red in the morning light.

He turned to look at Uzumaki Huiyi, who was still asleep beside him. Her pale red hair was scattered around her, and her breathing was even and peaceful.

He took a deep breath and gently placed a hand on Megumi's shoulder.

"Megumi, help me cultivate!"

He murmured silently to himself, then lowered his head and kissed her.

"Sanpo... you... you're... so bad... this early in the morning... you're already... mm... mm!"

Uzumaki Huiyi protested in her half-awake state, but his forcefulness quickly drowned out her resistance.

As the two moved in perfect harmony, Uchiha Sanpo felt a familiar warm current circulate through his body.

The system prompt immediately rang in his mind.

"Ding, the host has completed one session of Dual Cultivation with his cultivation partner: Uzumaki Huiyi. Basic Uzumaki Sage Body experience +25, chakra limit +3, Yang Release +0.01%"

"Ding, upgrade requirements fulfilled. Basic Uzumaki Sage Body successfully upgraded!"

"Ding, congratulations, host. You have obtained the Intermediate Uzumaki Sage Body!"

In an instant, an unprecedented surge of power erupted within his body like a flood.

Every cell in his body rejoiced, as though parched land had finally received sweet rain. His blood raced through his veins, and chakra flowed through his meridians more than three times faster than before.

Uchiha Sanpo clenched his teeth, fine beads of sweat appearing on his forehead. He could feel his body transforming, almost beyond what he could endure.

Kekkei Genkai: Intermediate Uzumaki Sage Body (500/2000)

Attributes: Lifespan +20 years, Vitality +1200, Chakra +1000, Vitality Recovery +10/hour, Sharingan Experience +20/day.

When the storm of energy finally subsided, he could hear the rustling of leaves rubbing together fifty meters outside the window. He could even feel that every beat of his heart was steadier and more powerful than before.

"Is this the power of the Intermediate Uzumaki Sage Body?"

Uchiha Sanpo muttered softly, unable to hide his excitement.

He impatiently called up the full system interface:

Host: Uchiha Sanpo

Strength: Shadow Level

Lifespan: 17/121

Cultivation Partners: Uzumaki Huiyi (Affection: 100%), Aoyama Yui (Affection: 60%)

Vitality: 2815/2815

Chakra: 2766/2766

Ocular Power: 1598/1598

...

Kekkei Genkai: Intermediate Uzumaki Sage Body (500/2000)

Kekkei Genkai: Three-Tomoe Sharingan (7300/10000)

"Shadow Level!"

Uchiha Sanpo clenched his fist and felt the surging power within his body.

"An ordinary jonin has around 600 chakra. I now have 2,766 points of chakra, 4.5 times that of an ordinary jonin. Right now, I'm a bit like Jiraiya without Sage Mode."

What delighted him most was that the Intermediate Uzumaki Sage Body could automatically add 20 points of Sharingan experience every day.

"Only 2,700 experience points remain before it upgrades to the Mangekyō Sharingan. At this rate, it will take 135 days."

If everyone encountered ads such as "Are you a real person?", there was no need to pay attention to them. Just close them; do not scan any codes or send text messages!

One hundred and thirty-five days was not long for a ninja, but for Sanfeng, who thirsted for power, every day was torment.

His gaze fell on the "Cultivation Partners" section of the system interface, and a bold thought surfaced in his mind. If I can find a woman in the clan with a Three-Tomoe Sharingan for Dual Cultivation, the rate at which I gain experience will definitely increase dramatically.

However, reality soon poured cold water over him. There were only a handful of women with a Three-Tomoe Sharingan, and the easiest one to approach was—Uchiha Mikoto, Uchiha Fugaku's wife.

"This... is a little difficult."

Uchiha Sanpo frowned. Uchiha Fugaku was not only the clan head, but also the captain of the Konoha Military Police Force. His strength was unfathomable. Setting his sights on his wife was no different from courting death.

"Sanpo, what are you thinking about?"

Uzumaki Huiyi's voice pulled him back from his thoughts.

"Megumi, help me transplant this Byakugan. I want to test its effects!"

Uchiha Sanpo took a nutrient jar from his ninja tool pouch. A pure white eyeball floated inside it.

Uzumaki Huiyi immediately frowned. "Are you crazy? The Byakugan is the Hyuga Clan's Kekkei Genkai. If they find out..."

Uchiha Sanpo interrupted her. "They won't find out. It's just an experiment; I'll switch it back soon. Besides, with my current strength and status, even if I stroll around in front of the Hyuga Clan, they wouldn't dare say anything."

Seeing the determination in his eyes, Uzumaki Huiyi knew she could not persuade him otherwise.

She sighed and took the nutrient jar. "Lie down."

Uzumaki Huiyi's hands glowed with the distinctive green chakra light of Medical Ninjutsu.

A sharp pain struck him. Uchiha Sanpo clenched his teeth and refused to make a sound.

He could feel his left eyeball being carefully removed and placed into another nutrient jar. Then a cold sensation came over him as the Byakugan was implanted into his eye socket.

Uzumaki Huiyi's voice trembled slightly. "All right, try channeling chakra into it."

Uchiha Sanpo slowly directed chakra toward his left eye. "Byakugan, activate!"

In an instant, his field of vision underwent a drastic transformation.

The world as he knew it was replaced by a strange transparent view. He could see the corridor beyond the room's walls, then the stones and trees in the courtyard outside, his vision stretching farther and farther.

"Wait!"

Uchiha Sanpo suddenly froze. By some strange impulse, his gaze passed through the wall of Uchiha Fugaku's house, where he discovered someone bathing.

Twenty-seven-year-old Uchiha Mikoto was at the most mature age for a woman... Water droplets slid down her graceful curves, while her wet black hair clung to her fair back.

Uchiha Mikoto.

Uchiha Sanpo's mouth went dry. He silently repeated, I didn't mean to do this, yet he could not look away.

"No wonder Sarutobi Hiruzen liked using the Telescope Technique to secretly watch wo—"

"Who are you peeking at?!"

Uzumaki Huiyi's angry voice, accompanied by a sharp pain from his left eye, pulled Uchiha Sanpo back to reality.

She held back the questions filling her heart, tears gathering in her red eyes.

"N-No one!"

Uchiha Sanpo hurriedly explained while rapidly thinking of a solution.

Suddenly, inspiration struck. He formed hand seals with both hands and used the Transcription Seal to seal the Byakugan's ocular power into the Three-Tomoe Sharingan in his right eye.

This way, even without the Byakugan, he would still be able to use its abilities.

"That was just an experiment, really! Help me remove the Byakugan."

As Uzumaki Huiyi performed the eye transplant surgery, she said shyly, "What's so good about peeking at? At worst, I'll let you look."

After the surgery, Uchiha Sanpo rested for twelve minutes before the vision in both eyes returned to normal.

Feeling the immense Byakugan ocular power within his right eye, he found it vastly different from the Sharingan's extreme ocular power.

Watching Uzumaki Huiyi leave, Uchiha Sanpo fell into deep thought.

Kekkei Genkai: Three-Tomoe Sharingan (7300/10000)

Remembering what he had seen through the Byakugan just now, he decided that he had to save Mikoto in the future.

If I can marry... Uchiha Mikoto... and bring her home...
