The incident of Rinjin creating a huge crater in the training ground was eventually brushed aside.

Ryōta Uchiha, traumatized by the event, was taken home by his parents.

After learning the full story from Ōzora Chūryū, his parents ultimately chose not to apologize to Rinjin.

However, Rinjin didn't care about such matters. While the Uchiha clan had some remarkably broad-minded individuals, most were rather unremarkable characters.

What made Rinjin happy was that Teacher Ōzora agreed to let him skip combat training, replacing it with tutoring sessions instead.

This arrangement satisfied Rinjin completely.

As long as he could return to the shop on time for his blacksmith work, everything else was a minor concern.

During the only afternoon class, Rinjin sat at the back of the classroom, next to the white-haired boy from the morning - Jiraiya.

The current Jiraiya sported a spiky, unkempt hairstyle, with downward-slanting eyes marked by two red lines painted with face paint, wearing a grey-green waist-length robe decorated with flame patterns.

"Rinjin, your strength is amazing! How did you train?"

Jiraiya lay on his desk, using the back of the student in front of him to block the teacher's view as he whispered.

Seeing this, Rinjin followed suit and lay down as well, whispering back, "Blacksmithing. When you swing a hammer enough times, you naturally get stronger."

"Can you teach me?" Jiraiya asked excitedly.

Rinjin immediately nodded, "I'll bring you a blacksmith's hammer next time. Find something solid to hit, keep hitting it every day, and you'll naturally get stronger."

Hearing this, Jiraiya was overjoyed.

He had experienced that tremendous power up close. Not just the destructive force, but the sheer presence was chilling.

Just thinking about possessing such power and being able to confess to Tsunade made him burst into happy laughter.

Rinjin couldn't help but smile too.

He had to admit, Jiraiya was genuinely fun to be around.

As they were laughing, Jiraiya pointed to the empty seat in front of Rinjin and asked curiously.

"Rinjin, do you know where that Ryōta Uchiha kid went?"

Rinjin was surprised - so that evil Uchiha kid sat right in front of him!

"Not sure, I think his parents took him home to change his pants," Rinjin scratched his head and made his guess.

Jiraiya didn't laugh. Instead, he sneakily moved closer to Rinjin, "Rinjin, you should be careful. Ryōta Uchiha is very petty. And his clan..."

Jiraiya didn't finish, but Rinjin got the message.

The Uchiha clan was indeed known for being petty, but Rinjin was even pettier.

At this thought, he suddenly realized an oversight in his plan.

If he had an enemy in Konoha, wouldn't that make Lord Tobirama trust him more?!

The answer was obvious, and the Uchiha would make perfect enemies.

First of all, the Uchiha clan wasn't doing as well in the village as one might imagine.

The clan's exclusivity was too strong, determined by the entire family atmosphere. As long as there were still elders from the Warring States period alive, that pride buried in their bones would continue generation after generation.

This completely contradicted the Will of Fire proposed by the First Hokage.

However, the Uchiha clan's powerful combat abilities were an indispensable part of Konoha, or rather, they were still a crucial component of Konoha's military strength.

If he became enemies with the Uchiha clan, then he, appearing isolated and helpless on the surface, would naturally gravitate towards the Hokage's faction for protection.

This way, his trustworthiness would gradually increase.

From the moment he entered Konoha and his plan was exposed, he had already been drawn into this great whirlpool.

And in politics, there was no such thing as staying neutral.

Thinking of this, Rinjin's eyes flickered slightly as he made his silent resolution.

Time flew by, and as the class ended, Rinjin left the ninja academy with the crowd of students.

As agreed, he now had to go work at the Katō Ninja Tools Shop.

With the advantage of his Magnet Release, Rinjin's forging skills became increasingly proficient, and the quality of his ninja tools improved. The reputation of the Katō Ninja Tools Shop gradually grew.

This led to a situation where the shop's ninja tools were in short supply.

Especially the senbon - according to news from the front lines, the senbon produced by the Katō Ninja Tools Shop were exceptionally sharp.

For ninja, their tools were their second life. Unreliable tools could be a nightmare.

The senbon forged by Rinjin were not only incredibly sharp but also maintained excellent durability, resulting in a particularly high recovery rate after battles.

Although this characteristic wasn't particularly profitable for the shop's business, on the battlefield, when supplies were low, these recovered senbon could be lifesaving!

Lifting the curtain, Rinjin entered the Katō Ninja Tools Shop.

Unlike his first visit, the shop was now bustling with activity. Many ninja wearing green vests moved about, examining and discussing the tools on display.

Master Ippongi rubbed his chubby hands together, wearing a merchant's smile as he weaved through the crowd.

Seeing Rinjin enter, Ippongi quickly rushed to his side.

"Oh, brother! What took you so long? Quick, we have several special custom orders here, come take a look and see if we can take them."

"How big are they?" Rinjin responded instinctively.

Hearing this, Ippongi threw an arm around Rinjin's shoulders, and with his free hand secretly made a figure "8" between them.

"My share?"

"Yours!"

Rinjin grinned broadly, knowing good times were ahead.

This large order wasn't just about the money - it was a sign that their reputation had been established.

In forging, especially weapon forging, quality was the foundation of everything.

With quality, everything else would follow.

Ninja who survived the battlefield were naturally the best advertisement, and the tools they used were automatically considered premium quality.

As they talked, Rinjin and Ippongi walked to the counter.

"Here are the orders: custom ninja swords for the Tsukikage family, armor plates for the Akimichi clan, and goods for my old man's trading journey. The old man's order isn't urgent, let him wait;

The important one is the Tsukikage family's ninja swords - they're big clients, please prioritize them."

Rinjin nodded, taking the orders from this filial son and headed into the forge.

It was amusing how Magnet Release provided an almost unfair advantage in blacksmithing, yet Rinjin still wasn't sure whether it was actually a kekkei genkai or not.

The rhythmic sound of hammering filled the air, accompanied by the whoosh of bellows, as time slowly passed.

At six o'clock, the Katō Ninja Tools Shop closed.

Rinjin wiped the sweat from his forehead, pretending to be exhausted as he walked out of the forge.

In the front room, Master Ippongi was excitedly hunched over the counter, his abacus beads clicking rapidly.

"Ah, Rinjin-kun, good work."

"Hey~ I worked so hard, don't I deserve a raise?" Rinjin grinned.

"A raise?" Ippongi's face froze as he slowly hugged the stacks of bills in front of him.

"You're joking again. We're partners sharing profits, I'm not your boss - how can I give you a raise?"

Seeing Ippongi's vigilant expression, Rinjin pouted, "We could always adjust the profit-sharing ratio."

Hearing this, Ippongi's chubby head shook like a rattle drum.

"No, no, no, Rinjin-kun, I'm an honest merchant. I never go back on my word."

Hearing this, Rinjin could only sigh helplessly.

"Fine, you're honest. The iron ore and charcoal will only last until tomorrow, remember to restock. I'm going home for dinner."

With that, Rinjin left the shop without looking back, leaving behind a distressed Ippongi wailing on the spot.

"Out again? We just restocked last week! Two weeks' worth of charcoal and iron ore! Damn it, Rinjin, don't go, come back!"

Rinjin ducked his head and vanished without a trace.

In a dense forest outside Konoha, Rinjin excitedly pulled out a bundle of weights from his chest.

These were weights he had forged from leftover materials. With the combined effects of his immense strength in forging and Magnet Release, these weights were small in volume but terrifyingly heavy.

There were four weights in total, wrapped in sturdy burlap bags.

The four weights combined approached 400 kilograms.

Rinjin attached the four weights to his arms and legs, and with the iron powder stored in his body, the total weight approached 500 kilograms.

Just wearing these weights made Rinjin feel like a lead weight - the kind that would definitely sink in water.

Standing up, he took two difficult steps, and immediately his muscles and bones began to groan. Rinjin knew this was his body's protest against the excessive burden.

However, this was exactly the effect Rinjin wanted.

He believed that once his body adapted to this weight, he could easily defeat a group of chūnin with pure physical strength alone.

As for why not jōnin - that was because those who became jōnin usually had some special qualities that ordinary people couldn't match.
