At a small river near Konoha, Naruto and Sasuke were training to tread water, and although they had completed their training in climbing trees and knew how to tread water, the difficulty of treading water and climbing trees was not at all level. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Trees are immobile, and as long as you maintain a certain amount of chakra on the soles of your feet, you can walk on them, which is relatively easy to master.

But treading water is different, water is moving all the time, and the chakra gathered on the soles of the feet also has to constantly change in order to stand and walk on the water, if you can't turn the changes to the chakra on the soles of your feet into energy, then this ninja is not a real ninja.

Although Naruto and Sasuke sank into the water again, they had made a great improvement compared to the beginning, which did not last until ten seconds at the beginning, and now it was only a morning, and they could stand on the water for more than twenty minutes, which is not a small improvement.

"You guys stop for a moment, and we'll rest." Seeing that they had been cultivating for a long time, Kratos asked them to take a break.

"No, I can continue!" Naruto said at the same time.

"That's really ......" Kratos shook his head helplessly after hearing their answer, then went over and grabbed them by the collar, lifted them up and said, "Cultivation is about combining work and rest, you have worked hard in the country of waves before, now you can relax." Don't spoil your body, know that the body is the capital of the revolution. ”

"But...... But ......" Naruto looked at Kratos with tears in his eyes and said with a crying voice, "Sakura has already surpassed us......"

"That's why you're working so hard?" Kratos really didn't expect the two of them to work so hard for this reason.

"Or else?" Sasuke asked rhetorically.

"Actually, you don't have to be like this, Sakura is just talented in this area, it's not that you are worse than her, after all, no one is perfect." These two children are really troublesome, and they need someone to enlighten them.

"Is that so?" Naruto asked incredulously.

"Of course!" Kratos swears, "You have something that Sakura doesn't have, and that's your background and bloodline, and you can quickly become stronger through these." But Sakura is different, she is just a civilian ninja with a bit of talent, and she can only become stronger by her own efforts. So don't be serious with her, be more considerate of her, Sakura is also your companion. ”

"This ......" The two looked at each other, exchanged opinions through eye contact, and then said, "We know ......"

With their agreement, Kratos nodded with satisfaction and said, "Rest for a while, I'll teach you a little bit of cultivation tricks by the way." ”

"Yo Xi!" As soon as Naruto heard that he had a trick, he immediately sat down next to Kratos and asked anxiously, "What trick?" Tell me! Tell me! ”

Little Tsundere Sasuke also pricked up his ears, wanting to hear what the trick was.

"Before I do that, let me ask, will you use shadow clones?" Will Naruto use Kratos to know, this question is mainly asked to Sasuke.

"I will." After Naruto answered, he asked suspiciously, "Could it be that the shadow clone has anything to do with the trick?" ”

"I do, too, but not very often." Sasuke said.

"Since you can all use it, it's much easier." Kratos nodded and said, "This trick can only be used by knowing the shadow clone, but before I can tell you about the usual role of the shadow clone." The shadow clone is mainly used to obtain information, as well as to check for traps, because the memories experienced by the shadow clone will be fed back to the main body. ”

"Hmm......" Naruto thought for a moment with his chin in his hand, then nodded, "I don't understand at all!" ”

"Is it too complicated for you? I'll keep it simple. Kratos forgot that Naruto's comprehension was so poor that he had to say it again in the most popular terms.

In other words, what you have done with the shadow clone, you will also know what the shadow clone has done when the shadow clone is lifted. Not only that, but even the progress of cultivation can be shared, and the speed of cultivating with a shadow clone can be described as a thousand miles a day. After saying that, Kratos checked again to see if Naruto understood, "Do you understand that?" ”

"I'm still a little incomprehensible, can you make it simpler?" As Kratos expected, Naruto really didn't understand.

"Big brother, do you want to express that cultivating with shadow clones is equivalent to cultivating multiple of yourself at the same time?" The quick-witted Sasuke has already guessed the answer.

"That's what it means!" Kratos immediately agreed, and said with a look of relief, "It's great that Sasuke can understand, unlike Naruto, who can't even hear such a simple thing." In the end, Kratos didn't forget to taunt Naruto.

"I know that too!" Naruto shouted unwillingly, then jumped up from the ground and made a shadow clone seal gesture and said, "Isn't it said that the more shadow clones cultivate together, the better the effect!" Look at me, the technique of multiple shadow clones! ”

As Naruto used ninjutsu, the entire riverbank was crowded with Naruto's shadow clones, probably about a hundred people.

Seeing Naruto use the shadow clone, Kratos covered his face speechlessly and said, "Can you listen to me first and then use it?" ”

"Oh......" Naruto said, picking up the shadow clone and sitting down to listen to Kratos again.

"The greater the number of shadow clones, the better the effect, but it is not without side effects, the shadow clones will not only feed back memories to the body, but even physical fatigue will also be fed back to the body." Kratos said solemnly: "In other words, if there are too many shadow clones, the fatigue that comes back when you disarm the spell can kill you, which is why the second generation Hokage has made multiple shadow clones a forbidden technique." ”

"That said, Naruto often fights with shadow clones, why is he okay?" Sasuke asked, remembering the situation when Naruto was fighting.

"This may be because of Naruto's own bloodline, the Uzumaki clan is originally known for a lot of chakras and strong vitality, and it is understandable that Naruto with strong vitality can withstand these fatigues, which is one of the reasons why I said that you are stronger than Sakura. Power from the bloodline. ”

In fact, Kratos still hasn't said one thing, the reason why Naruto was able to withstand this huge fatigue was not only the bloodline of the Uzumaki clan, but also the treatment of the Nine Lamas.

"I see...... "Sasuke knew for the first time that the power that came from the bloodline was one of the reasons why they were stronger than the others.
