Thinking of this, Zhang Han immediately took action. Raising the palm of the hand, a ball of natural energy was absorbed in the center of the palm, and then carefully injected his own spiritual power.

As soon as spiritual power and natural energy meet, they naturally merge. There was no need for Zhang Han to even distract himself from experimenting with the ingredients needed to combine the two energies.

"Try the clone technique."

Zhang Han controlled the chakra that had just been made in his palm, and slowly covered the surface of his body, according to the order of the seals on the scroll, while sealing them, he simulated the flow direction of the chakra in his body.

"Bump!"

There was a soft thud, and a cloud of white smoke covered the body.

When the smoke cleared, a clone identical to Zhang Han appeared next to him.

"It worked!"

Zhang Han looked at the clone that was exactly the same as himself in surprise, and his fingers carefully touched the other party, but he passed directly through the clone, and the clone that had just been separated disappeared immediately after.

The doppelganger technique is different from the shadow doppelganger technique, the separated body is only a phantom, with no entity and no attack power, and it will disappear when touched.

"Try the stand-in again."

Zhang Han made a few seals with great interest, and when he touched it, a burst of smoke appeared, and his body successfully replaced the position with the wooden stake outside the window.

"Then, it's the transformation technique!"

……

After half an hour, Zhang Han performed the three-body technique several times in a row before he finally calmed down. Sensing the spiritual pressure in his body, his face couldn't help but change.

"How can it be so expensive?!"

After only performing a few three-body techniques, it cost him one-tenth of his spiritual pressure, which is not much more than the high-level ghost path!

"Could it be...... Is it because you have to maintain the chakra outside the body, so you will consume so much mental power? Zhang Han thought about it for a while, and then understood the key.

If you can release chakra out of the body, you can generally only do it if you have a middle ninja or above, and if you cover the chakra all over your body, you must at least reach a high ninja or above.

And like Zhang Han, not only to maintain the chakra outside the body, but also to use it to make form changes, the consumption of spiritual power is not ordinarily large, even the elite Shangnin may not dare to play like this!

"In this case, the three-body technique is a bit of a chicken rib!"

Originally, he wanted to practice the three-body technique to the point where it could be instantaneous without sealing, but compared to the consumption of mental power, Zhang Han still gave up.

"Let's try the Spiral Pill!"

Zhang Han spread out his right palm again, and a ball of natural energy slowly condensed in the palm of his palm, which combined with the spiritual pressure gushing out of his body, and gradually began to rotate.

One, two, three...... It wasn't until the rapidly rotating light blue ball was about the size of his palm that Zhang Han stopped the input of spiritual pressure.

"It's less than the cost of stand-in!" Zhang Han rubbed his chin with his left hand and looked down at the spiral pill in his palm, "Sure enough, if you don't need to maintain the chakra on the surface of your body, the consumption of spiritual pressure is very small!" Try the power. ”

Zhang Han stomped his feet, flew out of the window, stopped in front of the stake in the middle of the courtyard, and pressed the spiral pill in his palm against the stake.

"Boom!"

With an astonishing popping sound and a piercing grinding sound, a round hole slightly larger than the palm of the hand appeared in the center of the stake, and it passed through the body.

"It's about as powerful as the Returning Spiral Pill, but it's not as silent as the Returning Spiral Pill, which destroys the opponent's body from the outside in."

Zhang Han reached out and touched the rotation marks left on the stake, and whispered.

Since Zhang Han created the Huidao Spiral Pill in the Corpse Soul Realm, the opponents he encountered were either too powerful or too vegetable, and he had not been able to find someone to test the power, and he felt a little regretful in his heart.

Since the chakra produced by Zhang Han is a combination of his own spiritual pressure and natural energy, it is very good for the meat. The consumption of the body is almost zero, and as long as the spiritual pressure is not exhausted, the chakra will continue to produce energy.

From this point of view, Zhang Han already has a chakra amount that surpasses the shadow level. Of course, due to the weakness of his physical strength, if Zhang Han doesn't need to go out of the state of death, he can barely deal with the middle ninja, and if he encounters the upper ninja, he will kneel nine times out of ten.

"Try it and see what happens when the Spiral Pill adds attribute changes."

For Naruto's S-level ninjutsu, Wind Escape, and Spiral Shuriken, Zhang Han has always been salivating, but he didn't have time to experiment. Now that I'm on the Hokage plane, I'm just using chakra for experiments.

The natural energy in the air is mixed with various attributes, and the first thing Zhang Han has to do is to separate the wind attribute and combine it with the spiritual pressure to form the wind attribute chakra. Then, control the wind attribute chakra to rotate disorderly in the palm of the hand, and finally form a stable spiral shuriken.

However, when Zhang Han used the wind attribute chakra to rotate at high speed, there was a sharp pain in his palm, as if he would be torn to pieces by a hurricane in the next second.

"Depressed! You still have to strengthen your body first! ”

Zhang Han was helpless, so he could only disperse the chakra in his palm.

After experimenting continuously for most of the night, his body was already exhausted, Zhang Han took out of his spirit body again, put his body on the bed, and began to practice Blade Zen......

……

A few days later, the Hokage Building.

Today's three generations of Hokage apes are in the prime of life, and although the Second Ninja World War has not yet broken out, the relationship between Konoha and Sand Ninja and Iwa Shinobi has fallen to a freezing point, and there are often frictions on the border of the Three Kingdoms.

Nowadays, ninjas who are on missions outside of the Land of Fire are often attacked inexplicably. There are big country ninjas and small country ninjas, and the contradictions between countries have skyrocketed, which has added more burdens to the three generations of Hokage for no reason.

"The above is the observation of my subordinates for many days."

A dark ninja wearing an animal mask knelt at his desk and reported to Miyo on his observations during this time.

Ape Fei Ri took a photo and looked at it for a long time, frowning and silent.

The photograph shows a stout wooden stake with a hole twice as large as a fist in the middle, surrounded by spiral lines.

"Is this the effect of ninjutsu? What an amazing change in form! ”

The third generation whispered, then raised his head and asked, "You mean, that little ghost has successfully controlled the spiritual power in his body?" ”

"Yes, three generations of adults! This is the conclusion that his subordinates have observed for many days. The Shadow Ninja replied without hesitation.

"That's ......" The third Hokage lowered his head again, carefully looking at the spiral wood grain around the round hole.

can be called 'Doctor of Ninjutsu', and the attainments of the three generations in ninjutsu are definitely not blown. However, even he couldn't tell what kind of ninjutsu Zhang Han used to break the stake, and the power of this ninjutsu was definitely not small, and it might even be above A.

"Keep watching!"

The three generations of Hokage pondered for a long time before he opened his mouth to give a word to the ninja of the shadows.

"Yes!"

The Shadow Ninja answered, and left the Hokage's office with a teleportation technique.
