Chakra metal had two effects.

First, it made ninja tools sharper.

Second, it increased the chakra conductivity of ninja tools.

Sharpness spoke for itself. Chakra conductivity was somewhat like electrical conductivity—every material was different.

Chakra metal had the best chakra conductivity, hence its high price.

In the original story, the ninjas who could afford to use chakra metal ninja tools were few and far between.

The Chakra Blades used by Sarutobi Hiruzen’s son, Sarutobi Asuma, were exactly chakra metal ninja tools.

Natsuki didn’t hesitate. He paid for this ninja sword called Neko-giri.

[Congratulations, Host. You have unlocked Kirigaya Kazuto Template Ability 3: Double Circular.]

As expected, it didn’t require Neko-giri to be famous to unlock.

With the matter concluded, Natsuki called Shirayuki and left the Ninja Cat clan’s territory.

A new day.

Natsuki arrived at the First Training Ground on time.

Before he even got close, he saw a tall figure over two meters tall.

Obviously, this wasn’t Sarutobi Hiruzen—but Monkey King Enma.

Enma was a monkey covered in silver-white fur, his entire body packed with muscle. He looked very powerful at first glance.

Unlike other summoning beasts, he also wore a Konoha forehead protector.

Natsuki inexplicably remembered a meme from his past life: Why did Enma want to kill Sarutobi Hiruzen?

"So you are Natsuki?"

Enma spoke human language.

"I am."

Natsuki replied.

"Fight me first."

Enma casually threw an iron staff at him.

Natsuki caught it. His mouth twitched.

If Enma’s test was staff techniques, he definitely wouldn’t pass.

Because he only knew kenjutsu.

"Watch out, kid!"

Enma didn’t give him much time to think. He charged.

His terrifying strength left shallow footprints on the ground wherever he passed.

Water Breathing: Second Form — Water Wheel!

Natsuki’s breathing became rapid.

His body spun in the air. The iron staff, carrying a stream of water, smashed toward Enma from mid-air.

Enma didn’t dodge or evade. He threw a double punch.

BANG!

A shockwave exploded in the air.

Natsuki was sent flying backward.

He hurriedly adjusted his body mid-air and landed safely.

Enma didn’t take this opportunity to attack—just standing in place, watching him.

After he landed, Enma leaped up.

BOOM!

The ground where he stood collapsed.

Enma reached mid-air, raised his right leg, and delivered a kick.

Reinforcement Magecraft!

Natsuki’s arms bulged slightly. His strength increased.

Water Breathing: Sixth Form — Whirlpool!

Natsuki twisted his body. A stream of water swirled around him like a water dragon.

As he swung the staff, the water dragon charged toward Enma.

Enma still took it head-on.

His Adamantine Body made him act like the sturdiest ninja tool.

A strong wind assailed Natsuki.

That terrifying strength reappeared.

Natsuki only felt his arms trembling.

He uncontrollably retreated backward.

And the iron staff carrying the water dragon landed on Enma’s body without causing any damage.

Natsuki’s mind raced. He used the momentum to float backward.

One-Sword Style: Iai — Lion’s Song!

After halting his body, he transformed into a beam of blade light and crashed into Enma.

Enma pressed down with both hands and pinned Natsuki’s iron staff.

Natsuki swung his left hand without hesitation. He took out the Sword of the Thunder God from his Shadow Space.

At the same time, he let go of the iron staff and gripped the Neko-giri he bought yesterday.

Double Circular!

Natsuki’s two swords erupted with astonishing speed.

They sliced through the air, actually creating a sound of tearing wind.

The two swords formed a fan shape like lightning.

And in the middle of the fan shape was Enma’s head.

Enma’s right hand was currently holding the iron staff. At the critical moment, he instinctively raised his left arm.

An ear-piercing sound rang out.

The sleeve on Enma’s left arm was immediately shredded. The two swords struck heavily on his left arm.

His body couldn’t help but sway—but that was all.

Enma suddenly swung his right arm. The iron staff swept out horizontally.

Shadow Assassin!

Natsuki slipped into the shadows, evading this staff strike.

"That’s enough."

Sarutobi Hiruzen, who was watching from the sidelines, spoke up.

Hearing this, Enma put away the iron staff.

Natsuki breathed a sigh of relief and dispelled Shadow Assassin.

Fighting up to this point, he could be considered to have exhausted his methods.

But due to Enma’s Adamantine Body, none of his attacks were effective.

If they continued fighting, he could only resort to cheating—using Shadow Assassin and the Logia-Type Plume-Plume Fruit.

Enma was obviously a physical-type summoning beast.

Natsuki couldn’t hurt him, and Enma couldn’t hit Natsuki either.

"Enma, what do you think?"

Sarutobi Hiruzen asked with a chuckle.

He was very satisfied with Natsuki.

To have such strength at nine years old—it would be hard to find a second person in the entire history of Konoha.

And has he already started researching the Dual Blades style?

"Good kenjutsu, but he doesn’t know staff techniques."

Enma evaluated. "He can become a contractor of the Monkey clan, but he cannot become my contractor."

Natsuki understood immediately.

Enma’s meaning was very simple.

Except for him, anyone in the Monkey clan could be summoned.

"I have no objections."

Natsuki said immediately.

As the Monkey King, Enma naturally had his pride.

Coupled with the fact that Natsuki didn’t know staff techniques and couldn’t bring out his full strength, it was understandable that he didn’t want to be summoned.

Fortunately, Enma didn’t completely shut the door.

Theoretically, as long as Natsuki learned staff techniques, Enma might still accept being summoned.

Natsuki couldn’t help but fall into thought.

In anime, which characters use a staff as a weapon?

Keyaru?

Ahem.

Natsuki hurriedly expelled the strange images from his head.

"Natsuki, sign your name here."

Sarutobi Hiruzen took out a scroll and reminded him. "This is the summoning contract scroll for the Monkey clan."

"Yes, Lord Hokage."

Natsuki took a pen from his Shadow Space and wrote his name on it.

Next to his name were Sarutobi Hiruzen and Sarutobi Shinnosuke. 𝘧𝘳𝘦ℯ𝓌𝘦𝒷𝘯𝑜𝑣𝘦𝓁.𝒸𝘰𝓂

The latter was undoubtedly Sarutobi Hiruzen’s eldest son—Konohamaru’s father.

In the original story, his name had actually never been mentioned—only that he was an ANBU ninja.

"Let’s go. I’ll take you to the Monkey clan."

Sarutobi Hiruzen put away the scroll. "You can choose one to be your regular summoning beast."

Theoretically, after becoming a contractor of the Monkey clan, one could summon all the monkeys.

But summoning beasts in the ninja world had intelligence and emotions.

Choosing one summoning beast as a regular partner allowed for better synergy and brought out its strength.

For example, after Uchiha Sasuke became a contractor of Ryuchi Cave, he chose Aoda as his regular summoning beast.

"Lord Hokage, I’m not very familiar with the Monkey clan."

Natsuki thought for a moment. "Could you recommend one? Preferably one with the ability to transform into a sword or blade."

"Due to the influence of the Sarutobi clan, most of the Monkey clan are more adept at transforming into the Adamantine Staff."

Sarutobi Hiruzen pondered. "But there are some with the ability to transform into swords and blades. I can recommend one to you."

"Thank you, Lord Hokage."

Natsuki followed him and soon met a monkey named Ensei.

[When the Monkey Ensei is summoned using the Ten Shadows Technique, its hardness is permanently increased by 30%.]

Perhaps because Sarutobi Hiruzen and Enma were present, Ensei agreed very readily.

Natsuki also unlocked Ensei as his summoning beast enhancement.

He could only say it was both tall and hard.

Ensei originally had an Adamantine Body, and now with a 30% increase in hardness, it would probably rival Enma.

In short—a massive gain.
