In Konoha, you call this a ninja tool?

clang!

The bellows whirred rhythmically, and the flames danced in the charcoal furnace.

The red-hot iron lump produced a series of crisp sounds as it was struck by the hammer.

A series of shapeless weapons,

Under Tianyu's continuous forging, it gradually took shape.

but,

He wasn't successful every time he tried to forge something.

If the forging fails, the resulting kunai will not have the ability to create a physical clone, and its use will be no different from that of an ordinary ninja tool kunai.

[Ding! Forging failed. Result: Ordinary Kunai]

[Ding! Forging failed. Result: Ordinary Kunai]

[Ding! Forging successful! Forging result: Clone Kunai *1!]

[Ding! Forging failed. Result: Ordinary Kunai]

……

The night passed quietly.

As darkness faded, the distant horizon began to lighten with the first hint of dawn.

"call--"

As dawn broke, Tianyu finally concluded his forging practice, which had lasted for several hours.

The arms that were used to swing the hammer were already sore, numb, and weak, making it difficult to even lift them.

Even after repeatedly exhausting his physical strength, recovering, exhausting it again, and recovering again, he had reached the physical limit that his body could withstand.

He slowly exhaled a breath of stale air.

Tenyu looked at the three black kunai lying quietly in his hand, their bodies gleaming with a cold, dark light, and a hint of satisfaction appeared in his eyes.

In one night,

He created a total of 3 clone kunai!

Furthermore, the proficiency in forging clone kunai has increased from 7% to 25%.

That was quite a fruitful experience!

After he carefully put away the three kunai...

Only then did he finally leave the forge, completely satisfied.

Only then did Tianyu notice the strong stench of sweat emanating from his clothes.

The forging of this night,

For Tianyu, who is only 6 years old,

It can be considered a rather difficult cultivation process.

Creating a clone kunai is not as simple as just swinging a hammer and pounding a rough iron billet.

While he was forging crude iron,

You also need to continuously input your chakra into it.

Therefore, in this forging process

Both physical strength and chakra consumption are extremely high for Tenyu.

After several hours of continuous forging, physical strength was repeatedly exhausted, and clothes were soaked with sweat several times, so a strong odor was normal.

Exhausted, Tianyu went to the bathroom to wash up.

Only then did I finally relax completely, collapse onto the bed, and fall into a deep sleep the moment I closed my eyes.

When Tianyu woke up again,

It was already noon.

Tenyu was left with a few rice balls for lunch every day, and then went to help out at the ninja tool shop, leaving Tenyu alone at home.

Tianyu quickly finished the rice ball and filled his stomach.

He plunged headlong into the forging shed and began to continue his forging practice.

In the blink of an eye, three days had passed.

For Tianyu,

The forging process,

It wasn't just about making kunai.

The process of creating the clone kunai also served as a workout for his physical muscle strength.

He now feels that his body has become stronger.

What surprised Tianyu even more was...

He became increasingly skilled at absorbing chakra within his body, and the amount of chakra he absorbed also increased compared to before.

The effects of this chakra refining training,

It is far superior to the secret techniques of the ninja clans in the village.

It can be said that after this kind of forging and training,

His starting point on the path of the ninja was no lower than anyone else's!

Chapter 3 Forging Cultivation

[Ding! Task issued: Clay (1000g)]

System Reward: Basic Forging Blueprint - Substitute Kunai

On the fourth day of Tianyu forging his clone Kunai

Suddenly, a notification sounded in his mind that the system had issued a task.

A substitute kunai?

Tianyu guessed in his heart

It is estimated that this kunai is used in a similar way to the clone kunai, and can exert an effect similar to the substitution technique.

This task is also very simple.

Clay is something that can be found everywhere, of course.

Tianyu quickly dug out a small pile of dark brown clay in the backyard garden.

[Ding! Mission complete!]

System Reward: Basic Forging Blueprint - Substitute Kunai has been issued!

Another way of crafting kunai immediately came to mind for Tianyu.

[Substitute Kunai:]

Forging difficulty: *

Skill: Instantly release a substitution jutsu

The process of creating a clone kunai is somewhat similar to that of creating a clone.

With his current understanding of forging clone kunai, forging substitute kunai became much easier for him.

After understanding the structure of the substitute kunai,

He immediately began to try forging.

However, this time he didn't seem to have the same luck as before.

The first substitute kunai failed...

The second substitute kunai failed...

The third substitute kunai, successful!

On his third forging attempt, he finally succeeded!

In Tianyu's mind,

Immediately, more information about the use of substitute kunai appeared.

[Substitute Kunai: After injecting chakra into a kunai, you can swap the kunai's position with your own to escape attacks.]

Tianyu nodded inwardly.

Just as he had guessed,

The effect of the substitution kunai is the same as that of the substitution technique.

The Substitution Technique, one of the three basic ninjutsu techniques.

It can be considered one of the most practical ninjutsu techniques in combat.

It is widely used in battles among ninjas of the Genin and Chunin levels, and is one of the most commonly used basic ninjutsu.

Furthermore, the substitute kunai is the same as the clone kunai.

Simply infuse your chakra into the substitute kunai; no hand seals are required to release it instantly.

It seems I'll have to forge a few more of these substitute kunai myself!

Tianyu was immediately filled with enthusiasm and began forging again.

clang!clang!clang!

The clanging of metal echoed intermittently from the forging shed.

Five days have passed in the blink of an eye.

Tenyu looked at the 15 clone kunai and 10 substitute kunai that he had successfully created and was very satisfied with the results.
