Hidden Otsutsuki.

Ray Shadow Cloning Technique!

boom!
The white eyes popped out, but the inside was empty.Obviously, it was a failure the first time.Yuling tried to add more lightning attributes to the ordinary chakra when using the shadow clone, but he couldn't find the balance, and the shadow clone was not successful.

"How about increasing the input of the thunder attribute?" He muttered to himself, and there was another movement in his hand.

Ray Shadow Cloning Technique!This time, Yuling added a little thunder attribute chakra to the original.

boom!
Still the same, only white smoke, no clone.

"Well, isn't 30.00% of the lightning attribute not enough? This is already one-tenth of my chakra. Forget it, let's start with a large amount of lightning attribute content." Seeing that it still doesn't work, Yu Ling was a little puzzled, but still insisted on trying.

boom!
This time it's not just white smoke, but also a lot of thunderstorms.

"Hey, this is..." Yu Ling seemed to have found a way of thinking, and continued to try.

80.00%！70.00%！60.00%！50.00%！40.00%！
Bang bang bang bang!
Still failed.Even Leiliu never appeared again.

"It shouldn't be. Could it be that the Leiliu just now wasn't the dissipation of the clone, but just an excess?" Yu Ling was a little confused. Could it be that his method was wrong?According to the foundation of Shadow Clone, it shouldn't be wrong.

"Hey, Yuling! Why is your chakra reaction so strong here? What kind of ninjutsu are you improving?" Naruto heard the slight crackling sound of thunder before, but now he feels that Yuling stopped experimenting and just ran over to play.

"I'm trying to make a lightning attribute shadow clone, but I added a lot of lightning attribute chakra, but they all failed."

"Hey, thunder clone. Then it's better to use all thunder. It's not like you don't have one." After speaking, Naruto felt that there was nothing interesting, so he went back to his place to practice Fengdun.

"Using all the thunder attributes...maybe it's really possible." Naruto's unintentional words, in Yuling's view, were indeed of great help.

"Perhaps, the point is not the amount of chakra, but the concentration of chakra. The lightning current only appears when the thunder attribute chakra reaches its peak... Could it be that we just need to remove other chakra attributes?" Just do it, Yu Ling formed a seal with both hands, and a human figure suddenly appeared beside him, but it exploded within a second.This time the thunder current was several times stronger than the one triggered before!
"Well, it's really feasible. It's just that there are too many chakras this time. Let's try to halve it."

Thunder clone technique!
boom!
"No, come again!"

……

Thunder clone technique!
Boom!
"Huh? It worked!" Yu Ling stared at Bai Yan with her eyes fixed, and there seemed to be a human figure inside, standing intact.This time, it only consumed one percent of the thunder attribute chakra in his body. This kind of chakra can be ignored in battle, and such a ninjutsu can only reach the consumption of E-level ninjutsu.

The thunder clone came out, and it didn't look much different from the shadow clone, except that Yuling could feel the thunder attribute chakra rioting in the thunder clone's body.

"It really is the most difficult to control Chakra."

In the experiment just now, Yuling was reduced by ten percent.Now he is going to use the thunder clone as a chakra storage space, or in other words, a sealed space, in increments of one percent.The sealing technique using the avatar as the carrier is powerful and not afraid of consumption.

……

"Kakashi doesn't have ninjutsu that suits me, so I'll find Yuling first." Sasuke practiced Fire Dungeon for a while after hitting a wall with Kakashi, but he didn't have a clue, so he thought of Yuling.Yu Ling still has a lot of B-level ninjutsu, maybe there is a thunder escape ninjutsu that suits him.

boom!
When he walked over, Yu Ling had just stood up.It looks like the development of a ninjutsu has just ended. "Yu Ling, do you have anything that you can teach me about Lightning Dunjutsu?" Sasuke didn't care about anything else, he only cared about what he could learn.

"Well, I think about it, you'd better use the long-range thunder escape attack. This can match your fire escape. How about thunder escape light arrow? This is a ninjutsu with strong penetration and persistence. You can control the launch time and distance according to your chakra input. But this is a C-level ninjutsu, and you can use it for development. Now its damage is limited."

"Okay, let's learn this." Now Sasuke is hungry, after all, Lei Dun has only mastered one Lei Dun · Ground Walking, and he has never seen the others, and he can't learn what he has seen.Yu Ling has a ready-made one, why don't you hurry up and learn how to use it?It doesn't matter if it's C or D.

"Chen-wei-mao-yin! Thunder Dun Light Arrow! That's it, I believe you can learn faster than Naruto."

"Thank you." After learning, Sasuke left.He also believes in his own ability, and he will definitely be able to learn this ninjutsu without Yuling's help.

As soon as Sasuke walked away, another Yuling came out from hiding.

"Phew, it's finally able to last for so long. Thunder Dun·Tian Lei Feng!"

boom!This time, there is no more white smoke, only a pure stream of thunder, frantically running and shaking in a small space.

"Now there should be an extra ninjutsu for survival. With this kind of Leiliu, no matter who it is, it will stagnate for a while." Yu Ling felt relieved, after all, this ninjutsu is very effective in actual combat.That is, it can be used as a clone to lure the enemy, and it can also launch the rear hand seal technique after being attacked to control the enemy's actions.In this way, the chakra of the thunder attribute can be used alone, and there will be less waste.

"Maybe, other attributes can also be used as clones. In this way, the use of ninjutsu can be more flexible. Let's start with the simplest entity, Chakra Earth."

……

"Huh! I don't know what happened to Yuling yet, but I learned his wind escape!" Three days later, Naruto succeeded, and as soon as his hand stopped, he was anxious to find Yuling to learn another one.

"Big idiot." Sasuke also stopped almost at the same time.Just now, he has fully mastered Lightning Arrow, and has developed two different forms of Light Arrow through different amounts of Lightning Chakra and Fire Chakra.The one with more fire attribute is attack enhancement, which is called Thunder Fire Explosive Arrow, while the other has more thunder attribute, which is specialized in penetrating power, and is called Thunder Fire Thorn Arrow.And Sasuke also wanted to use this ninjutsu to show off to the benchmark in his heart, Yuling.

However, it was obvious that they didn't need to go to Yu Ling again, he had already returned.Beside him are five clones of Yu Ling.
