*The Country of Fire, Konoha Ninja Village.*

Inside a dilapidated, abandoned building:

"The divine medical system has been successfully activated."

**Host:** Reiki [7 years old] 

**Ninjutsu Rank:** 4 

**Physical Constitution:** 5 

**Chakra:** 10 

**[Genin Overall Value: 10]** 

**Item:** Novice Gift Pack 

**System Function:** Portable Space [1000 cubic meters] 

**Holy Hands and Benevolent Heart:** Gain treatment points by healing any creature + surprise gift packages 

**Wealth:** 

Reiki had transmigrated into the world of *Naruto*. Despite being here for hours, he still felt unsettled. His past life had ended suddenly after a grueling month of overtime, leaving him to face the harshness of life once more in this world.

His new reality was grim. In this timeline, the Second Great Ninja War had taken his parents, and he had barely survived in the orphanage. Now, he faced Konoha's darkest era, with new genin sent to the battlefield, unqualified and unprepared. To survive, he knew he'd need self-protection skills fast—failing that, he wouldn't even make it to the third war's start.

"Wait, a god-level medical system?" Reiki snapped himself out of his grim thoughts, glancing at his system panel with new interest.

"Open the novice gift pack!"

"Ding! Congratulations to the host for obtaining primary medical skills, fixed chakra (50), and a physical constitution increase of +5."

A warm flow surged through his body, and in an instant, Reiki mastered the *Primary Treatment Technique*.

**[Primary Treatment Technique: Repairs simple wounds, alleviates minor poisoning, and clears infections.]**

With his enhanced constitution, Reiki's body felt stronger. He took a shaky breath, examining his abilities.

"Can I earn rewards by healing? Then…"

Without hesitation, Reiki picked up a kunai lying nearby and cut the back of his hand.

"Heal!" he commanded, releasing the technique. Green light emanated from his palm, sealing the wound in minutes, consuming a fixed 10 points of chakra.

"Ding! Host healed a wound, earning 8 healing points and a surprise gift package."

"It works!" Reiki's eyes brightened. But just then…

"Ding! System bug detected and corrected. Compensation gift package issued."

"What? I can't even exploit a little loophole?" he muttered.

Reiki shrugged, realizing he'd have to play by the rules. Becoming stronger was priority.

"Open the surprise gift package and compensation gift package."

"Ding! Physical constitution +4, solid chakra +20." 

"Ding! Physical constitution +4, solid chakra +10, and Ninjutsu - Thunder Release: Thunder Walk!"

**[System Ninjutsu: Instantly cast without seals, prioritizing fixed chakra.]**

"No seals, instant jutsu," Reiki mused, realizing the advantage. It would save him the time and risk of missteps during casting. This system was truly a game-changer.

At that moment, the old door creaked open. A 10-year-old boy named Chuan, the building's "boss," stepped in. Known for bullying the weaker orphans and stealing their allowance, Chuan often targeted those like Reiki.

"You—what are you doing?" Chuan demanded, sizing up Reiki, his usual intimidation tactic. But this time, Reiki's gaze was different.

"Stay out of my way!" Reiki replied, his voice steady.

Chuan, startled, quickly shook it off and raised a fist to charge. But before he could act, Reiki smacked him with a quick, controlled slap, sending him sprawling.

"Ding! Injured person detected. Would you like to treat him?"

Surprised, Reiki saw a radar-like screen appear, scanning Chuan's injuries.

"Sorry, Chuan-senpai, I didn't mean to hit you. Let me heal that up," he said, using his healing jutsu. Chuan, too stunned to react, decided to play along, hoping to retaliate once he felt better.

"Ding! Host healed redness and swelling, earning 1 healing point, +1 physical constitution, and +1 solid chakra."

"That's it?" Reiki muttered, realizing that minor injuries didn't yield much. Then a thought dawned on him.

With a smile, Reiki looked down at Chuan, who was beginning to rise. Before Chuan could react, Reiki activated *Thunder Release: Thunder Walk,* a spark of lightning sending Chuan reeling back to the floor.

"Ding! Injured person detected…"

Reiki grinned, testing his theory.

"Don't come any closer!" Chuan stammered, eyes widening.

But Reiki stepped forward, his fists ready, eager to test out his newfound powers.

For a few moments, the abandoned building echoed with screams and cries as Reiki continued his training…
