At that time, if Rin Kong threw the Boundary Break Kuwu up again, right in front of Lei Luo's head, then he might be killed in an instant, and he wouldn't even need the reverse current and zero, so he would die.

After all, in the sub-light state, Lei Luo himself can't react, and the automatic trigger of the boundary break, to a certain extent, seems to be an attack mode specially developed to restrain a high-speed ninja like him.

Rin Kong, this person is really not simple.

'This Yuyin remnant, Hanzo's disciple, was able to create an offensive Flying Thunder God ninjutsu that even the Thousand Hands and the Bo Feng Shui Gate couldn't imagine with a set of incomplete Flying Thunder God materials, and he could indeed be called a rare talent. ’

"If you can successfully recruit Rin Kong into your subordinates and use it to help me develop ninjutsu in space, I think I can also increase the development progress of the black domain from the side, but unfortunately, with the deep hatred between the other party and me, there is no possibility of using it for me." ’

Having personally experienced the power of the Flying Thunder God Mutant Attack Ninjutsu, Lei Luo really has a bit of a hot talent and research ability, just like he treats Orochimaru, he has always liked to recruit geniuses in the development of techniques.

After all, this is also for the sake of improving one's own strength.

But Rin Kong, since he was captured and imprisoned, even though Lei Luo went to the prison many times to interview him and showed no guilt in the past, Rin Kong still chose to resist death, according to his words:

"You Lei Luo sent people to kill my teacher, destroy my village and country, and still want me to die for you? Dream on. ”

Lei Luo estimated that if he really released Rin Kong from the shackles of the seal, the other party was afraid that he would not be able to understand his sincerity at all, and he would use the Flying Thunder God to escape when he turned his head, and then attack himself and Konoha again.

This is an avenger in the true sense of the word, his mind is full of hatred, anger and other emotions, and he only wants to take revenge on Lei Luo wholeheartedly, and the two sides can't get along harmoniously at all, and it's really a bit impractical to solicit each other.

But Lei Luo cherishes talents, and he is reluctant to kill Rin Kong completely, so he has to imprison the other party temporarily, and leave it for later, maybe in the future, stop the water and return to Konoha to brainwash Rin Kong?

In short, anything can happen in the ninja world.

"Four generations of adults, do you want to try the sound again?"

The voice of the vortex jade branch sounded, with a hint of inquiry in his tone, Lei Luo's thoughts were interrupted, and he nodded without much thought, and then walked to the table, holding the row of flying thunder gods in his hands, stuck between the five fingers of his hands.

Five on the left hand and five on the right hand, for a total of ten.

The researchers removed the metal wall that had been cut in half and replaced it with an intact one, Lei Luo's arms briefly accumulated, and then he swung outward, and ten kunai sliced through the air and flew towards the target, sending a scream in the air.

The kunai throwing technique used by Lei Luo was quite skillful, and although the kunai was thrown at the same time, the distance between them was very large, forming a widespread metal frenzy in the air, piercing the metal wall like raindrops.

Then, as soon as the thought moved, the technique in his hand was cast, and after just three or five seals......

Ten flying thunder god kunai, their tips all extended black spells, like pitch-black lines spread out to the surroundings at high speed, lines connected with each other, entangled, and finally formed a large net ten meters long and wide.

The pitch-black net panned through the air, and in an instant it came to the metal wall, perfectly enveloping the target, and then, a sneering cutting sound sounded together, but it seemed to come out at the same time.

In the next moment, the kunai and the black lines all disappeared, and the metal wall disintegrated and collapsed, as if it had been filtered by a sharp sieve, and in an instant it was broken into pieces of meat, and the shredded meat fell to the ground with a bang, splashing a cloud of dust.

Intently staring at the damage he had caused, Lei Luo lowered his arm, his eyes flickering, and he was deeply impressed by the Flying Thunder God Technique. Be amazed by the destructive power and development ideas of the resounding sound.

Flying Thor's Art. Absolute sound, although this technique is essentially the same as the attack effect of slashing the sky and breaking the boundary, but both the range and the attack frequency have increased too much, and it is almost not inferior to the complete shattering like the dust escape.

Absolute Sound is an advanced usage of the second stage of the void, and it combines some of the ideas of the boundary break, converting the kunai of one or two pieces into a ten-digit kunai, and connecting them into a formation to launch a covering group attack.

This is equivalent to the caster actively triggering the large black net, and then automatically capturing the target in contact by spatial transfer, in order to create countless line cuts, and the body is divided, causing a devastating blow to the victim like a corpse.

The most important thing is that although the attack density has been increased, the speed has not decreased much, and the kunai can spread out the formation in flight, as long as it can actually hit the target, then the absolute sound will inevitably cause damage to the target.

However, the fly in the ointment is that if you use Jue Xiang, the caster will be under too much pressure in terms of mental power consumption, chakra consumption, concentration and other aspects, resulting in the inability to make other actions on his own.

At this point, whether it is the creation of this technique, or the Lei Luo who has learned this technique, there is no difference, after all, I want to know that the difficulty of controlling one or two pieces of slashing kunai and controlling ten pieces of slashing kunai cannot be compared.

'Flying Thor's Technique. The development potential of the absolute sound is very high, from all dimensions, this technique is extremely destructive, and the attack speed is not slow, if you cooperate with my electromagnetic escape, at the same time control hundreds of kunai unfold attack arrays......

That effect must be extraordinary. ’

Lei Luo was thinking about things here, and over there, all the researchers looked at the metal wall that had been cut into a pile of pieces, and they all smacked their tongues, including the Flying Thunder God Technique. I was amazed by the power of the sound, and I was also shocked by the learning speed of the four generations of adults.

If I'm not mistaken, the four generations of adults should have just started the ninjutsu of the Slash series, right?

can learn so quickly, worthy of being a man who is invincible in the ninja world.

What the researchers didn't know was that Lei Luo's cultivation foundation was extremely solid, not only did he far surpass normal humans in terms of mental strength and physical fitness, but even various techniques had already been honed to the point of perfection and peaking.

Whether it is conventional ninjutsu, physical illusion, five elements retreat technique, various family secret techniques, blood inheritance limits, or sealing techniques that are difficult for ordinary people to master, space ninjutsu, immortal arts, and even yin and yang escape techniques, and the six realms of art, they are all involved, and there are almost no shortcomings.

It is not an exaggeration to say that Lei Luo is the number one ninjutsu master in the ninja world, even when Ape Fei Sun was at his peak, he mastered all kinds of ninjutsu far less than him, not as broad as him, not as deep as him, and his knowledge is completely incomparable.

With Lei Luo's various ability values, the experience of developing ninjutsu and learning ninjutsu, plus the talent of space ninjutsu is not weak, and there is still time to accelerate the efficiency......

With all the above factors, it is not surprising that Lei Luo spent a month or two learning the Empty Series Ninjutsu and was able to use it completely in the first experiment.
