As night fell, Natsuhiko, as always, walked in the direction of his home after solving the dinner problem at the Double Happiness Ramen Shop.

Along the way, he was still thinking about what had happened in the Sealing Office.

Although what Kushina said made him think a little crooked at first, as she continued to speak, Natsuhiko also understood what she meant.

In fact, she just wanted Xia Yan to practice with her from time to time to assist her in her cultivation.

Although she usually competes with Grandma Mito or Sister Tsunade, because her strength is too far apart, she can't accurately judge how many pounds and taels she has.

And Xia Yan, who is his own age, has traveled to the ninja world and is well-informed and experienced in a hundred battles, which happens to be a wonderful benchmark that can make Jiu Sinai recognize how much strength he has.

However, in the ninja world, inviting others to practice together is a very sensitive thing.

After all, in the battle of ninjas, intelligence occupies a very important place.

If you are not a relative or friend, you generally will not make this kind of request to each other casually.

Although Jiu Sinai has big nerves, he will not be unaware of this taboo.

Therefore, Xia Yan was a little happy that Jiu Sinai made this kind of request to him.

Because this means that this Jiu Sinai's friendliness to himself has unconsciously been quite high.

It seems that you can continue to bully her more in the future, and you are not afraid that she will suddenly become famous.

Xia Yan couldn't help but have such thoughts in his heart.

As for Jiu Sinai's invitation to learn, Xia Yan finally agreed.

After all, this is obviously a special event that has reached a certain level of favorability, so of course it has to be completed.

And since he didn't go out on a mission, Xia Yan found that he lacked actual combat training, his body was a little stiff, and his newly developed moves had no chance to be tested, so he had always been prepared to solve this problem.

Originally, he wanted to find a corner teacher to be a lucky viewer to test his moves.

However, since there is a fragrant girl who volunteers to be this experiment, Xia Yan naturally will not continue to choose the option of greasy uncle.

……

After a while, Xia Yan returned to his home.

Unlike usual, as soon as he entered the door today, he didn't hear the footsteps of three small ones running over, and the whole room was quiet.

However, Xia Yan was not surprised.

He changed his shoes and went into the house, put down his clutter, and walked down the stairs to the basement of his house.

This basement is not a large space, full of various materials and miscellaneous items, and some tools for processing materials are placed in the corners.

Xia Yan walked straight to an empty wall and stood up, his hands quickly forming a seal.

Immediately, the wall in front of him began to emerge with cumbersome and obscure runic spells, and finally they were connected to form a circular circle.

A chakra wave rippled out from the center of the circle, silently passing through Natsuhiko's body and covering the entire basement.

After waiting for a while, Xia Yan heard the sound of a click.

Then the floor in front of him began to separate from side to side, revealing a staircase leading to the lower floor.

After the sound stopped, Xia Yan walked down the stairs.

Click......

After Xia Yan walked down, the floor closed automatically.

The entire basement has once again returned to its usual tranquility.

Xia Yan walked down the passage, and at the same time, with a slight lift of his hand, a ball of light emitting a soft light appeared in front of him, illuminating the originally dark passage as if it were day.

Not long after Xia Yan left, he came to a secret basement located deeper in his home.

It can be seen that this basement is made of soil to dig out space in the ground, the area is not small, and the lights are bright, but there are a lot of debris and dust on the ground, and the construction has obviously not been completed.

At the same time, it is full of all kinds of strange equipment and instruments, which makes people feel unaware.

It is worth mentioning that the walls of the basement are also painted with quite a few runes.

They form a common shielding circle.

It is possible to avoid the prying eyes of various chakra methods, even the white eyes.

It can be said that it is a necessary magic circle for every ninja in Konoha Hidden Village.

Even ordinary ninjas will grit their teeth and buy themselves a set after a little savings.

To be honest, if it weren't for this thing, I'm afraid no ninja would want to be neighbors with the Hyuga clan.

After all, no one likes to live a life where they can be snooped on at every moment.

But the Hyuga clan doesn't have to worry about this thing turning their eyes into ornaments on the battlefield.

In addition to the fact that this shielding array is expensive and troublesome to arrange.

What's more, the area where the shielding circle is in effect will turn pitch black.

Although it is impossible to see through, this situation is like a firefly in the dark, which is easier to attract attention and cannot achieve the effect of a sneak attack.

In the center of the room, a strange machine with a large area is running, and various indicators on it are constantly flashing.

It can be seen that it is made of a computer that is still rare, and various materials that depict runic techniques.

This chakrapunk-style big guy is actually the original body of Xia Yan's chakra brain, the prototype he originally built.

Whenever Xia Yan came here and saw this old fellow, he would remember that he had sealed it in a scroll and carried it with him.

While it is on a mission in various places, it will be able to collect various materials to upgrade its eventful years.

When people are old, they always like to miss the past.

Sixteen-year-old Xia Yan sighed.

Although Natsuhiko now has a more advanced chakra brain made of chakra metal, the machine continues to shine in this basement, assisting his clones in various research tasks.

is his important partner.

It's like the Pokémon that Ash threw at Dr. Oki's house at the end of each season.

Thinking of the youth he spent with himself, Xia Yan couldn't help but be moved.

So he reached out and patted his old buddy hard as a sign of condolence.

As soon as he finished shooting, his old buddy spewed out a screw out of nowhere, and white smoke began to rise from several connections, and a shrill whistle sounded - almost stretched out his feet and died suddenly......

Xia Yan's raised hand froze instantly, and he didn't dare to move at all.

After picking up a huge wrench, taking out two rolls of adhesive tape, and skillfully giving the old guy first aid, Xia Yan finally breathed a sigh of relief.

"I shouldn't have any big problems thinking about it."

He comforted himself.

Could it be that you can blow up the whole Konoha into the sky?

After that, wait for the clones to have time and then hand it over to them to solve.

Natsuhiko clapped his hands and walked around the machine to the other end of the basement.

Here, Xia Yan finally saw his three infant clones.

I saw three small dots gathered around an unfinished machine, holding a hammer and a wrench electric drill in their hands, and the installation work was in full swing.

That picture, like a child driving a big car, makes people want to call the police when they look at it.

Hearing Xia Yan's footsteps, the three little ones were not as enthusiastic as usual, they just glanced at him lightly, and then lowered their heads and continued their busy work.

Xia Yan scratched his head.

The three little guys actually don't play dad terriers today, which makes him a little unaccustomed.

Sure enough, every boy likes to be called daddy, no matter whether the other party is male or female.

Even yourself.

However, from the brief glance of the three little ones just now, he still sensed the resentment in their eyes that was about to overflow.

Grievances from workers.

But this is also a matter of no way, in order to make the various machines needed before the opening of the tavern, Xia Yan even stopped the research task for the three children, and asked them to concentrate on these machines first.

Working in this basement day and night, it's no wonder they have such a big grudge.

Although the three little ones are essentially their own shadow clones, Xia Yan is still a little weak-hearted.

After all, Sanxiao is just really experiencing these hard work, and he just receives memories while sleeping, as if he had a dream.

That's a lot more comfortable.

The only thing that worries him a little is that when he dreamed recently,

From time to time, you will dream of yourself being hanged under a street lamp......
