Back at home, Ye Qiu couldn't wait to turn on the newly upgraded system.

Looking at the fetters of more than 5,000 points in the lower right corner, Ye Qiu struggled mentally for a long time before he could barely suppress his urge to open five times and ten consecutive draws.

Forget it, save a little bit, Naruto will need a threshold fee of 5,000 points to advance.

Take a look at what's in this update.

Main menu.

Cavitation breakthrough.

Naruto's meridian diagram reappeared in Ye Qiu's mind.

At the same time as Naruto's meridian diagram appeared, there was also a subtle ray of light that connected to Naruto next to him.

And a thread to connect it?

I didn't notice it just now.

It seems that Naruto must be nearby to see the meridian diagram in his body.

No wonder Kushina asked me to bring Naruto.

It turned out to be a live demonstration.

Of the air pockets in Naruto's body, only the first air pocket in his head was illuminated, and everything else was pitch black.

Chakra can only circulate in the range of the head, and if you want to go to other parts, it will be extremely difficult to break through each air pocket.

If the chakra circulation is not smooth, the strength of the ninja will naturally not be able to rise.

It seems that only by breaking through the air pockets will Naruto's chakra level increase.

Chakra level is also an important indicator of a ninja's progression.

The known chakra level is 5000, from level 1 to level 5000, which corresponds to which stage the ninja can advance to.

If Chakra level 1 is a D-rank ninja, then at level 20, you can meet the advanced conditions of C-rank.

Of course, whether you can successfully advance or not also needs the support of many external conditions.

Just like Naruto's Iruka bonds, Mizuki bonds, and various specific ninja equipment, they are external conditions.

These external conditions are secrets that human beings have been studying for so many years and have not been able to break through.

Who made them not read the original Hokage.

But the Chakra level is the final result of years of experimentation by ninja scientists.

From D grade to SSS grade, the corresponding chakra grades are:

Class D, Level 1.

Grade C, Grade 20.

Class B, Class 100.

Class A, Class 200.

S-class, 500-class.

SS class, 1000 class.

SSS class, 5000 class.

As long as the chakra level is reached, you can move up.

If the Chakra level is not reached, the Advancement will not be triggered even if the external conditions for the Advancement are met.

Of course, the threshold fee bond value is also indispensable.

That's why it's so difficult to advance in ninja.

Naruto had been cultivating for so long before he broke through the air pocket in his head, and the devil knows how those guys at the school trained ninjas.

It's still up to you.

Sleepless nights.

Until he got up the next day, Ye Qiu was still in a state of excitement, full of energy, and didn't want to sleep at all.

However, Jiu Sinai had dark circles under her eyes, yawned, and looked listless.

"Little cuties, come and eat~~ I have your favorite ramen today~~"

Mama Ye had already gotten up and prepared their favorite ramen for Naruto and Kushina.

This is pulled by Mama Ye herself, and the taste is not much better than that of Yile ramen.

Forced by life, living alone with a baby all year round has allowed Ye's mother to practice exquisite cooking skills.

"Wow~~"

Both Naruto and Kushina stared at the ramen on the table, pounced like hungry tigers, and gulped down without an image.

During the noodle eating, they were still grabbing each other's famous rolls in each other's bowls, how could they look like half a mother and son.

"Eat slowly, everyone has a share, don't grab it."

Mama Ye patiently persuaded and showed an embarrassing smile.

This scene made Ye Qiu speechless for a while.

This is like a mother and son, saying that they are sisters and brothers is almost the same.

But Ye Qiu is not qualified to talk about others, and his relationship with his mother does not look like a mother and son.

Single-parent families will inevitably raise some strange things that are difficult for ordinary people to understand.

"Sister Ling, I have to go out today, and I guess I will come back very late, so you don't have to wait for me to eat at night."

"It's okay, it's okay if you don't come back, today there is Jiu Sinai with others, so people won't be lonely~~"

As she spoke, Ye Ma and Jiu Sinai looked at each other, and both of them showed mysterious smiles.

[Excitement from Kushina, Bond +75]

I'll go, unload the mill and kill the donkey, I was a little cute to Naruto yesterday, and I don't need to come back today.

With my mother's temper, she can still raise me so big.

Hell knows what I've been through all these years.

I'm going to school today to deal with the make-up exam.

That Iruka trainer last night was so timely.

Provides a large number of valuable Iruka-specific bonds.

Let Naruto's originally confused path to advancement suddenly see the direction clearly.

It saved Ye Qiu a lot of time.

But when it came to that Iruka trainer, Ye Qiu still had some doubts in his heart.

How could it be so coincidental?

You know, in a huge city, how difficult it is to find someone.

And he's a person he doesn't know at all.

It is not clear whether he is male or female, tall, short, fat and thin, old or young.

But Ye Qiu was just touched by it.

If it's lucky, it's too lucky.

If you have such good luck, why not draw 9 'Thank you for your patronage' in a row.

After a night of precipitation, Ye Qiu's excited heart gradually calmed down, and many questions that had been covered by his mood gradually surfaced in his mind.

Why is that guy there?

It's like he's looking for me.

What does he ask me for?

Is it just to give me bonding value?

Ye Qiu didn't believe that there were such good people in the world.

And it happens to be a specific ninja advanced by Naruto, and the odds are too small.

Wait, advanced?

The specific ninja that Naruto advanced to was Iruka.

Then on the other hand, the specific ninja that Iruka advanced to is also Naruto.

Do they know the mystery of ninja advancement?

It's impossible, there is no original Hokage in this world.

Maybe it's just a coincidence.

Maybe that guy knows some of Iruka's advanced eyebrows.

With questions in his heart, Ye Qiu got on the bus to Xiaoying's house.

Naruto was still in front of the window, admiring the scenery outside the window.

Last night, the girl in the red dress said that after opening the meridian acupoint map, she would be able to use the ancestral rune stone.

Anyway, being idle in the car is idle, so it's better to let Naruto try the effect.

Ye Qiu's mind moved, and the mysterious rune stone with a simple style in his backpack appeared in front of Ye Qiu.

"Naruto, look."

Naruto ignored Ye Qiu and was still looking at the scenery outside the window.

"Naruto, don't look at it, look at what this is."

Ye Qiu dragged Naruto down from the window and shoved the rune stone into Naruto's hand.

Naruto twisted his neck reluctantly, and just wanted to protest, but was instantly attracted by the rune stone in his hand.

"Wow Wow~~"

Naruto screamed twice excitedly, as if he had gotten something great.

Naruto opened his mouth wide and swallowed the rune stone into his stomach.

I'm not afraid that the rune stone will be too hard and choke.

"Hey, why don't you eat directly, aren't you afraid of knocking your teeth?"

Equal~~

At the moment when Naruto ate the rune stone, the meridian acupoint diagram in Ye Qiu's mind suddenly lit up, and on the only lit air pocket on his head, a pattern that was exactly the same as the one on the rune stone appeared.

It's like the rune stone has been inlaid with it.

With the inlay of the rune stones, the entire meridian diagram also shook a little, as if a strange change had occurred.

The chakra flow in the meridians is faster, and the flow is increasing.

The three unlit air pockets around the rune stone also became flickering and dimming, and they were at the critical point that were about to be lit.

I'm going, this is called cavitation breakthrough?

It turned out that this rune stone was directly inlaid into the meridians.

Embedded in Naruto's body was supposed to be a chakra runestone.

There are five types of runes: Chakra runes, strength runes, defense runes, ninjutsu runes, and speed runes.

Chakra Runestone, as the name suggests, is to increase the number of chakras and improve the sustainability of ninjas.

And so on.

Strength Rune increases the ninja's strength and explosive power.

Defensive runes improve the ninja's ability to resist attacks.

Ninjutsu Rune Stone increases the ninjutsu power of ninjas.

Speed Runes increase the speed of the ninja, including movement speed, seal speed, and chakra condensation speed.

It's a shortcut to improving the strength of ninjas.

But the disadvantages are also very obvious.

Ordinary runes can only be inlaid on the ninja to improve the quality of the ninja tool.

Although it can also improve the combat effectiveness of ninjas, after all, it is a foreign object, and there will be disadvantages such as losing the ninja equipment and being shot down by the opponent.

If the enemy picks up your ninja gear, it will really be a stealing of chickens and rice.

But if the rune stone can be embedded in the ninja's body, it will solve these problems perfectly.

It's such a good thing to kill people and sell goods.

Before you know it, the bus has arrived at its destination.

Xiaoying's home.
