Naruto: I didn't say this is the real Hokage.

“Wow~Aaaaaaa…”

Extreme pain came over Naruto, veins popped all over his body, blood continued to pulsate in the bulging blood vessels;

It made Naruto's entire naked upper body seem as if it was crawling with dense earthworms;

It also seems to be engraved with ancient and mysterious patterns with special powers.

The deep red that emanated from his flesh and blood and bones became the perfect background color, making the various changes in Naruto's body seem even more poignant and tragic.

Bones, muscles, nerves, skin...

Even the ends of every hair seemed to be wailing at this moment, constantly telling Naruto that they had reached their limit.

His hands and feet were no longer under his control, and his consciousness had long since become blurred, but Naruto, carrying a thousand-pound boulder, still mechanically squatted, stood up, ran, and climbed...

In this not very big training ground, almost every inch of land is covered with some of Naruto's blood and sweat.

boom! ! !

The old man Whitebeard outside the field threw a punch in the air, directly shattering the boulder on Naruto's back into pieces.

Whitebeard couldn't stand it any longer. He wondered if Naruto continued to train like this...

It's really possible that Naruto would kill himself here.

"Gulala la la la~ That's enough Naruto, take a break first.

Come here and talk to me, Dad."

"Huff, huff... OK, dad."

The shattering of the boulder made Naruto feel a lightness on his back, and his mind gradually became clear again.

Whitebeard was right, he really needed a rest.

Naruto gasped and walked towards the old man with white beard, and then...

Paji~

Naruto fell flat on his face. It was obvious that this body, which had already reached its limit, would no longer be able to provide Naruto with the strength to walk once it relaxed.

Naruto: (?﹏?) …

Whitebeard Father: ⊙_⊙……

"...I'll come over."

Old man Whitebeard walked over, bent down and picked up Naruto.

"Ah~Ah?! Ah!!! Daddy, be gentle...be gentle~"

At this moment, Whitebeard only needs to lightly touch Naruto's body to make his beloved eldest son feel what it is like to be in ecstasy.

Whitebeard Dad: (ー_ー)!!

[Is it really that exaggerated? !

No... you've already squeezed your body into this state, why are you still training?! 】

Old man Whitebeard carefully carried Naruto under the tree and let him sit down leaning against the trunk.

Whitebeard could feel that Naruto's physical condition was much worse than he thought.

It's a pity that Marco didn't come to this world, otherwise with his Phoenix Flame...

Even if it cannot restore Naruto's body, it can greatly alleviate Naruto's pain at the moment.

As for Whitebeard himself...

There's no way, Old Man Whitebeard really doesn't understand anything about treatment.

Apart from fighting and collecting his son, he was just... well, drinking...

……

"Naruto, are you okay?"

"Phew~Thanks for your concern, Dad. I feel much better now."

After an unknown amount of time, Naruto finally recovered, the blush on his face and the veins wrapped around his body gradually fading away.

“Gulala la la la~ That’s good.

Naruto~

Just listen to your dad's advice... Since Kaio-ken is so difficult to practice, you might as well give up.

With Dad and the others protecting you, it doesn't matter if you are a little weak."

This is the nth time that Whitebeard has persuaded Naruto in this way.

Naruto had never told anyone except his father Whitebeard about his training of the Kaio-ken. Even his mother Kushina didn't know about it.

Because the training method of Kaio-ken is indeed extremely painful;

The various abnormalities that the body exhibits during training are terrifying, the kind that will give you nightmares just by looking at them...

Naruto didn't want to make others worry about him, so he naturally didn't plan to tell them.

And the reason why Whitebeard knew that Naruto was practicing Kaio-ken...

There was no way. There were some things that an eight-year-old kid like him could not do.

For example:

This training ground was found by Father Whitebeard;

The thousand-pound boulder that Naruto just carried was also chopped out by Whitebeard's father himself using the Kusakumo knife...

"It's okay, Dad, I can handle this.

Besides...my physical condition is not as bad as you see."

Naruto did not deceive Father Whitebeard with this statement.

Thanks to the great strain placed on the body when practicing the Kaio-ken, Naruto could feel that the Uzumaki bloodline in his body was slowly activating, and would soon be fully awakened;

In addition, the Nine-Tailed Fox in his body is continuously supplying chakra to Naruto's body, speeding up his recovery...

Once Naruto stops training, his body will gradually recover at a considerable speed, which is why he has been able to hide it from others including Kushina until now.

It's just a pity for Kurama. Ever since Naruto started practicing Kaio-ken, this big fox has never gained weight again.

Moreover, the Nine Lamas are shrinking visibly every three days...

Naruto began to worry that if he continued training like this, the strongest tailed beast Kurama might die in his hands.

Naruto: [Kurouma, are you okay? ]

Kurama: (ー ー゛)…

Kurama said that he didn't want to talk to Naruto, and put a big lock on Naruto's consciousness space.

……

"Naruto, I don't understand why you are practicing this Kaio-ken so hard?!"

"...You don't understand my difficulties, Dad."

[The reason why I’m working so hard is to prevent myself from being killed by the dog system.

woohoo~

Who in the family understands? !

o(╥﹏╥)o ……】

The pain from using a 1x Kaio-ken was enough to make Naruto feel like he was dying, so just imagine the pain from using a 50x Kaio-ken...

It's going to kill people, right?!

It will definitely kill people, right?!

By the way, can't the Kaio-ken only be trained to twenty times its maximum strength?

Where the hell did you get this fifty times pain from, dog system? !

So now Naruto dare not slack off for a moment, and truly practices to the point of practicing to death as long as he doesn't die.

There are only five days left before the deadline given by the dog system.

Naruto felt that with his current progress, he should be able to learn the Double Kaio-ken in five days...right?

"...Forget it, Dad, I won't advise you anymore, just know what's going on.

By the way, are you free in ten days?"

"should have."

If the system task is completed successfully, Naruto estimates that he will spend a lot of time lying at home in ten days.

"Dad, why are you asking this? Is there something you need my help with?"

"Gulala la la la la~

Actually, it’s nothing big. Xiaoxue is going to come to Yuyin Village to see me.

I am just thinking about letting you brothers and sisters have a proper meeting~"

Naruto: ⊙_⊙? ? ?

[Who? Xiaoxue... Oh, I remember now.]

Fenghua Xiaoxue, the daughter adopted by my father...】

[It is detected that Fenghua Xiaoxue is about to visit Yuyin Village. The system now issues a task:

...]
