Douluo's shadow poisonous milk

After the Unparalleled Dragon and Snake couple left, everyone gathered around them.

Ning Rongrong took the lead, pulled Ning Jiu's ear and said: "Xiao Jiu, the Qibao Glazed Sect is an authentic sect, where do these messy things come from? What kind of seven-step heartbreak, half-step with a smile, if you don't do it today Let’s make things clear and see how I deal with you.”

The Qibao Glazed Sect has always been a great and upright sect in Ning Rongrong's mind. When she listened to Ning Jiu's nonsense just now, she just resisted and did not deal with him. Now that the enemy is gone, she can finally let go. .

"It hurts, it hurts, cousin, please be gentle. I made up all that stuff like half-stepping with a smile and Jiuhua Jade Dew Pills. Otherwise, how could I have deceived those two people?" Ning Jiu didn't know how to deal with his cousin. There is no way.

"That's right." Satisfied, Ning Rongrong applied another three points of force to the hand holding Ning Jiu's ear and twisted it hard.

"Tell me, why did dad give this communicator to you but not to me? How come I never knew there was this thing in the sect? If you have anything else to hide, tell me." Ning Rongrong raised his hands Arms akimbo, looking like a victorious little hen.

"Communicator, Sister Rongrong, is this what you are talking about?"

Then Ning Jiu took out the jade pendant from his arms and explained to Ning Rongrong: "Cousin, look. I have placed some small mechanisms in this jade pendant. As long as the soul power is input, it will shine. .”

With the input of Ning Jiu's soul power, the jade pendant indeed began to glow, and then Ning Fengzhi's voice came out: "Xiao Jiu, what do you want from me?"

Ning Rongrong grabbed the jade medal and shouted excitedly to the jade pendant: "My father is me. I am Rongrong. I heard what you said. I miss you so much." The eldest lady turned on the invincible coquettish mode. , but unfortunately, there was no response from the other side.

Ning Rongrong looked at Ning Jiu in confusion, that shouldn't be the case. Every time he used his coquettish technique, his father would dote on him.But this time, my father didn't respond at all. It was weird. There must be something weird in this. Could it be that the communication was interrupted?

Ning Jiu laughed awkwardly, took the jade token from Ning Rongrong's hand, and pressed it somewhere. At this time, Ning Fengzhi's voice came out again: "Just take care of this matter. "

Ning Rongrong was confused for a moment. Why was her father's words so inconsistent?

However, a few smart people such as Flanders and Tang San saw the clues.

Especially Flanders. He took out the jade card from Ning Jiu's hand and observed it carefully. He found that there was a place on the front and back of the jade card that seemed to be pressable.

He pressed it curiously, and then Ning Fengzhi's magnetic voice came out.

"Xiaojiu, what do you want from me?"

"You can handle this matter yourself."

Until then, even the stupidest person could see the clues. It turned out that Ning Jiu somehow recorded these two paragraphs of Ning Fengzhi into the jade pendant, and then played them repeatedly.

"How amazing!" Everyone couldn't help but marvel, and they didn't know how Ning Jiu stored the sound.

Although everyone was curious, it involved Ning Jiu's secret, so everyone felt that they didn't ask questions. Only Ning Rongrong was full of curiosity.

"Xiaojiu, how did you do this? It's so amazing."

Although Ning Rongrong was the only one asking, everyone's ears were stretched out. Everyone was curious. If they could satisfy their own curiosity without involving each other's secrets, then what's the point? Why not?

This is not a secret. To Ning Jiu, it is just a simple electromagnetic principle.

Brother Xiao Jiu lived up to everyone's expectations. Ning Jiu smiled and said to everyone: "Actually, it's not a secret. When recording, the sound causes the jade pendant to generate an induced current that changes with the sound. This audio current is amplified by the amplifier circuit. Then, it enters the coil of the recording head, and a magnetic field that changes with the audio current is generated in the gap of the head. Under the action of the magnetic field, the magnetic signal of the sound is recorded on this piece of jade Perry."

What a simple truth. After Ning Jiu finished speaking, he looked at everyone and asked casually: "The working principle is so simple. Does everyone understand it?"

Ning Jiu's seemingly casual question made everyone confused. What the hell, is this so simple?Did your kid do this on purpose?

Even Yu Xiaogang, the most knowledgeable and talented among them all, looked confused at this time. What did he just hear?

What is induced current?What is an amplifier circuit?And what is a magnetic head?What is that magnetic field at the end?Why so many weird words?

"Did everyone understand? Do you want me to explain it in detail again?" Ning Jiu asked.

Dai Mubai, Tang San and other students looked confused, while Flanders and Zhao Wuji, as deans and teachers, if they said they didn't understand at this time, it would be a great loss to the prestige of the academy.

Flanders nodded and said: "I didn't expect Xiaojiu to learn this step by himself. It's amazing. It's really amazing. Even when I was young, I wasn't as smart as Xiaojiu is now."

Zhao Wuji also gave a thumbs up and said: "Yes, Xiaojiu, you are right."

The simplest and most effective way to resolve embarrassment is to just praise.

"It's so complicated. I don't understand it at all. Third brother, do you understand what Xiaojiu is talking about?" Xiao Wu asked first.

Tang San shook his head and said to Xiao Wu: "I don't understand what Brother Xiaojiu is talking about. Dean Flanders must know. He is well-informed. If you don't understand, just ask Dean Flanders Grow it."

"Ahem, the weather is so sunny today! Everyone pack up and prepare to leave here. After all, this is the Star Forest. At night, something uncontrollable may happen. What will happen when everyone returns to the academy? Let’s discuss the issue slowly.”

When Flanders saw Xiao Wu's eyes turned towards him, he quickly stopped the topic and cursed Tang San in his heart: "What are you talking about? Let Xiao Wu come to me to answer. You see, I look like I know how to do it." Answer man?If Xiao Wu comes to ask a question and I can't answer it, do you really think that the dean is shameless?

Seeing Flanders interrupting, everyone wisely gave up on the problem and let the damn induced current and amplification circuit go to hell.

After solving the mystery of the jade pendant's sound transmission, everyone looked at Ning Jiu with a trace of respect. This was respect for knowledge.

Including Ning Rongrong, no one asked Ning Jiu about the secret of the so-called Nine Heavens Divine Thunder, which saved Ning Jiu a lot of things.

This is different from the sound transmission jade pendant, which can represent real lethality. Judging from Ning Jiu's performance, I am afraid that soul masters below the soul king may be affected by it.
