Naruto: Can't learn ninjutsu? I'll just practice immortality!

Asakawa Naoki was unaware of the conversation between Yu Bi and Yu Mo.

At this moment, his avatar was still in the Hidden Rain Village, but his main body had come to the Sky City, which was more than 6,000 meters high.

After the transformation, the Sky City was much more beautiful than before. It was no longer a few big heads like before, but a real flying castle.

The energy of the Zero-Tailed Void, which was powered by the darkness of human hearts, was quite sufficient, so that the Sky City could fly at an altitude of 6,000 meters for a long time without worrying about running out of energy.

However, flying in and out of the Sky City required flying with a sword, which was a bit troublesome.

Therefore, Asakawa Naoki was going to refine a teleportation array!

The teleportation array was a kind of application of the power of space, and it was a relatively advanced array.

Therefore, even if it was a teleportation array in the same world, it would require at least four or more patterns of restrictions.

And the advanced teleportation array across the world even required more than seven patterns of restrictions, and at least required the cultivation of refining the spirit and returning to the void to perform it.

Fortunately, Naoki Asakawa now only needs to connect Sky City and Hidden Rain Village, and only needs four-pattern prohibitions.

When he just broke through the middle stage of Qi Refining and Spiritualization, he could refine a complete set of four-pattern spiritual weapon flying swords. Now it is not difficult to refine this teleportation array.

The reason why he did not refine the teleportation array before was mainly because he did not have spirit stones.

Although the Zero-Tailed Void imprisoned in Sky City can also be used as energy, this energy is not very stable. As the energy of the teleportation array, Naoki Asakawa is worried about problems.

Now he has enough spirit stones, which can not only provide energy for the teleportation array, but also can refine many arrays that require spirit stones.

Action is worse than thought. Naoki Asakawa immediately refined a teleportation array, one of which was placed in the square of Sky City and the other in his office in Hidden Rain Village.

"With the teleportation array, maybe Kushina and the others can meet." Naoki Asakawa suddenly thought.

When he saved Nagato's parents and Uzumaki Kaori, he wanted Kushina to meet them and let Kushina know that even now that the Uzumaki clan is extinct, she is not alone.

Thinking of this, Asakawa Naoki once again refined a teleportation array to connect the Sky City and his own hut.

"Huh~"

"Finally done."

Asakawa Naoki wiped the non-existent sweat. The teleportation array is indeed a formation involving space, and it is much more difficult than the Five Elements Absolute Breath Array and the Three Demons Subduing Demon Array.

After selecting a few relatively pure spirit stones and embedding them into the two teleportation arrays in the Sky City, Asakawa Naoki returned to the office of the Hidden Rain Village and embedded the spirit stones in the teleportation array in the office.

"In this way, there should be no problem."

"However, it is better to use the Senzu Bean clone to test this dangerous formation."

After thinking about it, Asakawa Naoki threw out a few Senzu Beans and controlled the Senzu Bean clone to walk into the teleportation array.

The teleportation array is different from other arrays. If the location of the teleportation is wrong, it is okay. The problem is that the teleportation process is wrong and encounters space cracks or something.

Space cracks are feared even by cultivators in the realm of refining spirit and returning to the void, not to mention Asakawa Naoki, a cultivator in the realm of refining qi and transforming spirit.

Once he touches the space crack, his mortal body in the acquired realm will probably be torn apart in an instant.

However, as the fairy bean clones entered the teleportation array one by one and were finally transported to the sky city intact, Asakawa Naoki finally gradually put his mind at ease.

For greater security, Asakawa Naoki ejected hundreds of fairy beans in his dantian, teleported them from the teleportation array in the office of the Hidden Rain Village to the sky city, and then from the sky city to his home in Konoha.

In the end, a full 100 teleportation array tests ended successfully, with a 100% yield rate, so it can be used with confidence.

When he returned to Konoha through the teleportation array, it was already a little late, so Asakawa Naoki practiced at home for a night.

It must be said that with the Yin Nine-Tail in his dantian to help absorb natural energy, and two spirit stones in his hands, Asakawa Naoki's training speed is really as fast as riding a rocket.

After practicing for a night, Asakawa Naoki rushed to the medical department early the next morning.

"Tsunade-sensei, I want to ask Kushina for a day off." Asakawa Naoki said.

"Oh," Tsunade nodded, she was no longer surprised, but still reminded:

"Don't be partial, kid, don't take Mikoto with you?"

"Well, this time it's Kushina's private matter, I'll take Mikoto out to play next time." Asakawa Naoki explained.

"Oh? Then when will we go to the casino together?" Tsunade smiled expectantly.

"Next time for sure!" Asakawa Naoki smiled.

Arriving at the office where Kushina and the other two were learning medical ninjutsu, Asakawa Naoki looked at Kushina who was learning medical ninjutsu.

"Kushina, come with me to a place today." Asakawa Naoki said."Where? Isn't Mikoto going?" Kushina asked curiously.

Although she wanted to monopolize Naoki Asakawa, she didn't want to sneak away.

"No, only you can go. Next time you go out to play, take Mikoto with you."

As he said that, Naoki Asakawa looked at Mikoto apologetically, but Mikoto responded with a look that didn't need to apologize.

"Go, Kushina, Naoki-kun has something important to ask you." Mikoto smiled indifferently.

She believed that Naoki Asakawa would not be partial in this regard, after all, he was a man who shamelessly said "I want it all".

After Kushina changed into her regular clothes and left the medical department, she kept looking at Naoki Asakawa curiously.

"Naoki, what do you want from me?" Kushina asked.

On weekdays, Naoki Asakawa was the best at keeping things to themselves. When he called them out to play or practice fairy arts, it was always Kushina and Mikoto together.

This time, calling her out alone really made Kushina unable to hold back her fantasies.

It is already the beginning of July, and her birthday is coming soon. Did Naoki prepare a special birthday gift for her?

Thinking of this, Kushina was looking forward to it.

"You will know in a while," Asakawa Naoki said with a smile:

"I have prepared a surprise for you!"

"Actually, there is no need to prepare so much. I like everything Naoki gives me." Kushina smiled:

"Anyway, birthdays are celebrated every year. As long as I can be with Naoki forever in the future, it will be the best gift."

"Uh." Asakawa Naoki was a little stunned. Kushina's birthday seemed to be on July 10th.

In the past few years, when Kushina celebrated her birthday, he was basically on the battlefield and didn't give her anything.

This time, the surprise prepared for Kushina happened to coincide with her birthday.

No matter what, let's take Kushina to meet Nagato and his son and Uzumaki Kaori first.

Arriving at home, Asakawa Naoki took Kushina to the front of the teleportation array in a room.

"Is this a sealing barrier?" Kushina asked curiously as she looked at the teleportation array.

As the princess of the Uzumaki clan, she was most familiar with sealing techniques, but she didn't recognize this teleportation array.
