It only took a moment to open his eyes, and Kakashi closed the Kaleidoscope Writing Wheel Eye, but it was also in this short moment that Kakashi could clearly feel that the chakra in his body was consumed violently, and his mental power was also consumed a lot.

"It's no wonder that Kakashi in the original book died from the use of a kaleidoscope. I'm afraid it's not just the chakra that is exhausted, but even the mental power is overused, and the two are superimposed, causing death. Kakashi muttered to himself.

Kakashi re-pulled the forehead guard and touched his silver-white hair, his expression a little helpless. Judging from the current situation, using Kamui once is probably the limit of Kakashi's use of the kaleidoscope.

But fortunately, it's just the beginning, and after becoming proficient, it won't be a problem to use it a few times, and as you get older, your mental power and chakra continue to grow, this number of times will become even more.

One of the big problems with the kaleidoscope is that it can't be used for practice, because if you use it too many times, you will lose your sight, which means that every time you use it is precious, and it is a violent thing to practice.

Unless you reach the height of the eternal kaleidoscope or have intercolumnar cells, you can use them unlimitedly.

Now that the kaleidoscope is open, there is a life-saving hole card, as long as the speed of use is accelerated, by surprise, even if it is a shadow-level powerhouse, Kakashi is confident that his head will be unscrewed off with divine power.

The Four Elephant Seals resurfaced, completely sealing the Sharingan, and the abundant chakra lingered in Kakashi's body again. The repeated use of the Four Elephant Seals has made Kakashi extremely skilled by now.

It is not difficult to seal and break the seal in an instant.

Under the moonlit night, Kakashi took out a thousand thunderbolts, jumped into the courtyard, and swung them again, but he didn't use a single chakra, he just kept waving them, and the exquisite sword technique bloomed in Kakashi's hands.

If someone takes a closer look, they will find that at this time, Kakashi's sword technique is already a little different from the original Hachiki sword technique, a little less fierce and a little more flexible.

A knife is faster than a knife, and the afterimages are repeated, with gusts of wind, printed with the bright moonlight, which looks particularly desolate.

The next day, Kakashi arrives at Kai's door early, and it just so happens that Kai is about to leave from home.

Seeing Kakashi, Kai was a little overjoyed and shouted, "Kakashi, your mission is over?" Let's have a showdown of youth! ”

Kakashi smiled and nodded, he naturally came to Kai today to practice physical arts, but before that, it would be a good choice to have a duel with Kai.

"Yo-hei, come on, Kakashi, what's going to be compared this time?" Kai said excitedly.

In Kai's opinion, since the Rebellion of the Nine-Tails, Kakashi no longer shirked his own competition, but seriously duel with himself, which made Kai very satisfied.

Although it is not known what caused Kakashi to make such a transformation, Kai doesn't care. Besides, with Kai's brain, it is estimated that even if he thinks about it, he can't think of an answer.

"Ah, let's go to the seventh exercise ground today and have a fight, and then I have something to ask you for."

"Yo Xi, let's go." Kai yelled excitedly and ran to the seventh training ground with a puff of smoke, as for what Kakashi said, Kai automatically ignored it for the time being.

Kakashi was a little helpless and immediately caught up with Kai's pace.

So, early in the morning, the name of Konoha saw two figures, one black and one green, running wildly in Konoha Village. The green figure in it was laughing as he ran, and those who didn't know thought it was a psychopath.

Kakashi couldn't help but distance himself from Kai, which was too embarrassing.

"It's worthy of being my eternal opponent, Kakashi, I'm going to speed up!" Kai yelled, and his movements were indeed faster.

The corners of Kakashi's mouth moved slightly, revealing a hint of curvature.

"Ah, that's fast, I'm not going to be left behind."

The two walked side by side and soon arrived at the No. 7 exercise site.

"Ahh This is youth! I didn't expect it to be a draw this time! Come on, let's have a bloody battle to decide the outcome of this time! ”

Kai finished and punched Kakashi.

As soon as Kakashi stopped, he looked at Kai and punched him, which was called a powerful sink, and Kakashi was sure that if he hit, he would probably have a bruise on his face.

The next one turned sideways and dodged the ferocious blow.

"Hey, Kai, let's talk before we start."

"Yo, Kakashi, where will the enemy tell you before they make a move, and I just said that."

Well, what you say makes a lot of sense, and you can't refute it yourself.

Kai didn't leave time for Kakashi to refute either.

Seeing Kakashi flash, Kai lifted his right foot and it was a flying kick.

Kakashi doesn't bother to talk nonsense, let's finish this battle first!

"Konoha Whirlwind!"

Seeing the steel-like leg sweeping over, Kakashi didn't dodge, but grabbed a kick directly, and then turned around and threw Kai directly out with his strength.

"Awesome! It's really worthy of being my eternal opponent, and I actually defused my Konoha whirlwind so easily, so let's take a look at the next move! Konoha Rigid Whirlwind! ”

A powerful air flow flashed through Kakashi's ears, and Kakashi's right eye froze, what a strong roundhouse kick!

Instantaneous!

With the strange way of exerting force under his feet, Kakashi disappeared in place in an instant.

Kai kicked into the air and looked around suspiciously.

"Hey, where did that Kakashi guy go, why did he disappear all of a sudden?"

Just as Kai was wondering, Kakashi's joking voice rang out behind Kai.

"Konoha Body Technique! Kill for a thousand years! ”

Kai was shocked and immediately shouted, "What kind of physical art is this?" How did I not know ......"

But before Kai could finish speaking, Kakashi showed tiger marks on the fingers of both hands behind Kai's back, and both hands used force at the same time, aiming directly at Kai's backyard!

"Ah!!h

Kai only had time to let out a scream, and then the whole person flew out.

Kakashi smiled with a treacherous smile, stood in place, looked at his fingers, and said secretly, "This trick is really a bit useful." ”

On the other hand, Kai covered his buttocks, looking pained, looked at Kakashi, and said, "Kakashi, what is the meaning of your physical technique?" How did I never hear of it, and ...... It's so powerful. ”

"Thousand years of killing!"

"What a domineering name! It's worthy of the mystery of Konoha Physique, is it Kakashi, you created it yourself? ”

"Ah, so to speak."

"It's really worthy of being the opponent of my life, this is youth, I didn't expect you to have created your own physical skills, damn it, I'm still standing still, no, I'm going to increase my training!"

Kai said, a fire of youth shooting out of his eyes.

"That Kai, you don't have to be so excited." Kakashi touched his hair and said helplessly.

But apparently, Kai has blocked all information distractions at this time, immersed in the world of his youth.
