In the laboratory, Orochimaru sat there fiddling with the bell, not saying a word.

Summoned in by Orochimaru but left aside, Hanzo couldn't guess what his intentions were. Hanzo, who was standing on the side, had no choice but to wait quietly for instructions.

The sound ......of bells echoed through the lab.

"Hanzo, you said how wonderful the world is, and those ordinary things also contain mysteries."

Looking at Orochimaru's sigh for no reason, Hanzo felt inexplicable.

Knowing that Hanzo didn't understand what he was saying, Orochimaru continued, "Have you ever thought that sound can do a lot of things. Explosions can cause temporary ringing in the ears and deafness, and some harsh sounds can make people feel sick. Speaking of which, Orochimaru also deliberately took out a kunai and pulled it on the bell, making a piercing sound.

Hearing this, Hanzo had some guesses, "Sound escape?" ”

Hanzo doesn't have much memory of the sound escape ninjutsu, neither too much power, and the number of appearances is also small, so it's a bit of a picture at the beginning.

"My lord, do you want to develop some ninjutsu that uses sound?"

"Hmm!"

"However, according to the characteristics of sound, it seems that it can only affect people's hearing, and I am afraid that the power is not very great."

Hanzo offered his opinion while trying to remember some knowledge about sound in his previous life. As for the sound escape ninjutsu Hanzo that Orochimaru's subordinates once used, he couldn't remember it at all, so he had to give up this cheating method of providing the direction of development by knowing ninjutsu.

"I know what you said, I hope you can come up with something constructive, my things are not given for nothing!" Speaking of this, Orochimaru said solemnly, and Yu Guang glanced over and met Hanzo's eyes.

"Yes!" Hanzo quickly responded. Although he was able to hold on under Orochimaru's eyes, Hanzo would not trouble himself, and he would only find guilt for himself if he was so hard-hearted.

After a killing rod, Orochimaru continued gently: "Of course, I don't require that you have to have great power, as long as the insights help me. Think about it again. ”

After pondering for a long time, Hanzo could only think of the scientific knowledge of his previous life, and had no other thoughts. There was no way, Hanzo had to say something scientific and see if he could cope with the past.

"If you really want me to talk about it, you don't have to worry about how to develop it, if you don't understand some basics, I'm afraid you won't be able to do anything."

"And what do you think should be done?" Orochimaru asked with interest.

"What is the nature of sound?" Hanzo directly threw out this question.

"Essence?" Orochimaru muttered the word, opened his mouth, and said nothing, because it was not easy to describe at all.

Hanzomoto wanted to directly throw out the definition of sound in the previous life, "Sound is actually the physiological effect of mechanical waves that travel through the air to the auditory organs and cause the auditory organs to react." But Hanzo was afraid that after Orochimaru got the definition, he would ask himself how he knew, and even if he didn't care about this, he would really use this to make some more development than the original plot in the original plot.

"I didn't think about that, I was thinking about the scope of its action. What I talked about before is acting on the physical side of people, and I also thought about acting on the spiritual side of people. ”

Although Hanzo didn't say anything specific, his question also gave Orochimaru an extra angle to think. Hanzo didn't know that the ninjutsu that used sound under Orochimaru's men in the plot was in these two directions, "cutting the air wave", "ringing through", and Tayuya playing the flute to perform illusions, which acted on the body and spirit respectively.

"Spiritually?" Hanzo frowned, and in terms of body, Hanzo could think of it, after all, infrasound waves would cause harm to the human body, but in terms of spirit, Hanzo really couldn't think of it.

Seeing Hanzo's doubts, Orochimaru asked Hanzo: "Hanzo, does good music make people feel happy, and can lullaby help people sleep?" ”

"That's right!"

"This is not to suggest that there is a real mental effect of sound." Orochimaru said proudly.

After being reminded by him, Hanzo found that he had indeed missed this effect, and there was no such technique as hypnosis in his previous life, which was hypnotized with words!

Although Hanzo was very disgusted with Orochimaru's character and practices, but in his heart, Orochimaru's ability to peep at the leopard in the tube was indeed admirable.

Orochimaru stood up at this time and looked at Hanzo, and said with satisfaction: "As an assistant, Hanzo, you are much better than God Know!" ”

"Thanks for the compliment." Hanzo was relieved when he heard Orochimaru say this, knowing that he had passed today's level, so he said with a smile.

"I'm telling the truth. God knows that this guy doesn't have any vision, so he guards his amphibious transformation plan, thinking about dominating the sea route, and his heart is focused on money, and the two subordinates and secret weapons he trained are wasted in his hands. ”

Previously, because of a certain communication with Tianzhi to ask him not to hide the two test subjects, Hanzo at this time was not nervous because of Orochimaru's words, and he was not worried about the charge of not reporting it, but the secret weapon had not been discovered, so he asked, "Secret weapon?" ”

"Yes, the secret weapon! Using a creature composed of core spirits and water, this technology can be used as an immortal technique if research continues, avoiding damage. I'll start this research when I'm done with the work at hand. Hanzo, you're a water ninja, if you apply this technology to the human body, will the probability of survival be very high? ”

When Orochimaru said this, Hanzo knew what he was talking about, that is, the monster called the Sea Emperor under the command of God in the plot. Thinking of this, Hanzo suddenly had a bold idea - could it be that this is how the Ghost Lantern Water Moon's hydration technique came about!

"And the abilities of his two subordinates also have a bit of a role, especially the one that stretches freely."

"Isn't it Chakra absorption?" Hanzo was a little confused. Orochimaru's opinion was completely opposite to his own, and Hanzo had always felt that the ability to absorb chakra was better than the physical changes.

"I have mastered this ability to expand and contract the body, and with this way of fighting, it will be more flexible, Chakra absorbs this ability, it has great flaws, one is the ability to endure, and there is a limit to how much Chakra can absorb. There is also how much to absorb must be released, otherwise you will not be able to call your own chakra. ”

After listening to Orochimaru's explanation, Hanzo realized that he didn't know enough of these two abilities, so he sentenced this ability to absorb chakra to death in his heart.

It's a pity that Hanzo didn't know that the neck that extended when Orochimaru planted the curse mark actually used this ability, otherwise Hanzo would have passed him with such a disgusting appearance.

After discussing it for so long, Orochimaru saw that the time was not early, and said, "It's not early, you go back, Hanzo." You'll be here for the next few days studying the sound stuff, and I'm going back to Konoha to attend the ceremony of the peace agreement between the five powers, and I'll have them cooperate with you when I'm away. ”

After speaking, he patted Hanzo's shoulder, "Don't be like God knows, remember, people only rely on themselves!" What you have in your own hands is your strength. ”

He then motioned for Hanzo to go back, leaving him alone in the lab......
