Later, he suddenly burst out laughing.

This made Hua Wei slightly nervous, thinking that he was crazy.

"Xia Lu, you calm down, it's really not okay, I can sacrifice myself and we go out together, I know you can't bear to let me die, but for you and Beicheng, I'm willing."

Hua Wei hugged Xia Lu slightly.

Xia Lu pushed him away.

At this point, he calmed down a bit.

"I'm not crazy, really, I understand everything."

Xia Lu held her shoulders and looked a little calmer.

Hua Weiwei looked at him carefully for a long time, and finally made sure that he was indeed not crazy, so he frowned.

Soon, a puzzled expression appeared on her face.

"Did you really figure it out? What the hell is going on? ”

She hurriedly asked Xia Lu.

Xia Lu smiled slightly, did not answer her immediately, but raised his hand to pluck one of her hairs, circled her fingers a few times, and then blocked her ears with his fingers.

Hua Weiwei played this kind of game when he was a child, and when he suddenly did it, he had to wonder if he was crazy.

"What are you doing!"

Hua Weiwei looked displeased.

Xia Lu ignored her, her fingers flicked on her hair, and Hua Weiwei immediately heard a slight buzzing sound.

"Did you hear that?"

Xia Lu's face showed an excited expression again.

Hua Wei smiled bitterly.

"Aren't you crazy after all, why are you playing this child's game with me?"

Xia Lu's expression became serious, and his voice became stern: "You listen carefully." ”

With that, he talked again.

Seeing his serious face, Hua Weiwei finally decided to be serious and listen carefully to the voice.

Soon, she noticed the anomaly.

"Echo!"

Hua Weiwei's face changed slightly.

There was a faint echo in the sound, like an echo in the hollow, but it would certainly not be heard unless you listened carefully.

"What the hell is going on?"

She looked up at Xia Lu.

"Because we're in a mirrored world, the voices you hear are two, one realistic and one mirrored."

Xia Lu immediately explained for her.

Mirror...... World? ”

Hua Wei's eyes widened slightly, and the expression on his face gradually became crying and laughing: "Can you say something I understand." ”

Looking at her, it seemed that she was doubting herself again, Xia Lu smiled slightly.

"Do you remember that Li Bin once said that the material of ancient weapons is hard because it is not completely exquisite, but moves at an extremely high frequency?"

"According to my inference, we should also be pulled into a vibrational frequency, like a mirrored world, not in another dimension, but in our original space where different frequencies have vibrate."

"Frequency, Vibration ......"

Hua Wei was slightly thoughtful.

When she was in school, she had learned that energy and matter in this world were actually vibrations.

Light is a wave, and gravity is a time-warping wave.

Matter itself vibrates at a frequency before it interacts.

In other words, when the copper in front of them sent out the business, it pulled them into a mirror world.

Perhaps this is also the reason why people's spiritual power has not completely disappeared, they have not disappeared, but have entered another vibration frequency, making it impossible for people to sense the Dao.

This theory, while bold, is not impossible.

Hua Weiwei's eyes lit up.

Soon, however, her face pulled down again.

"Even if you're right, how are we supposed to get out?"

Xia Lu smiled slightly when he heard this.

"You can't remember, when the witch appeared just now, only you could see her, but I couldn't see her."

"It stands to reason that we are all pulled into the spirit world you are talking about, and we should all be able to see her, why are you the only one who can?"

"The reason is that although this thing can change the frequency of matter, it can't change the frequency of energy, which means that my body is pulled into a certain vibration frequency by it, but what I can sense is only the energy frequency of the original world."

"And you have the meat pill in your body, it comes from the underworld, and the underworld is a mutant body triggered by the spiritual power of the dead, so the underworld should be able to sense the energy of the same frequency, but you can sense the energy frequency of both worlds at the same time, so you can see her."

Hearing this, Hua Weiwei thought about it seriously.

What Xia Lu said was not difficult to understand, she understood it after thinking about it carefully.

"And then?"

Now she is not concerned about how to get out, but about Xia Lu's theory.

She has always linked the theories that Xia Lu said with the spirit world she came into contact with, and by now, she has basically completely integrated the mythical ghosts and gods with Xia Lu's theories.

"You attacked it just now, and it reacted immediately, at the time we thought it was fighting back, but now that we think about it, it's more like an echo, it's just affected by its own vibration frequency, which amplifies the spiritual power you emit, it's more like a resonance."

"That is, it can resonate with your spiritual power."

Hearing this, Hua Wei changed color slightly.

This thing can't change the frequency of energy, that is, it can't change the frequency of one's own mental power.

And its own energy frequency is different from their original world, and there is only one reason why they can resonate with him, that is, their own spiritual power frequency has changed.

Meat Dan!

A strange feeling rose in Hua Weiwei's psychology.

Xia Lu's voice hadn't stopped.

"We could see it outside the tomb just now, and when we entered the tomb, we could still see it after the body frequency was changed, that is, this kind of thing existed in the form of two frequencies."

"And we can hear its sound on the outside and hear it inside, which also means that it can emit two frequencies of spiritual power, so I was thinking that if you can establish a connection with it, maybe you can change its operating frequency and pull us back to the original world."

Hearing his words, Hua Weiwei's eyes quickly flashed.

Although Xia Lu's theory is incredible, it is the most reasonable explanation she can think of so far.

Suddenly, she sounded something.

Just now the witch said that she needs to teach her the soul herself before she can help herself, and the soul she understands is her spiritual power.

Could it be that she wants to use her mental power to control the copper rundown?

Thinking of this, her eyes lit up and she immediately wanted to try it.

Soon, however, she remembered something else and frowned.

"However, it reacts very much to my psychic power, and if I try to establish a spiritual connection with it, it will react even more."

She is a psychic powerhouse, and she is very resistant to psychic power.

But Xia Lu is not a spiritual powerhouse, once his spiritual power is too strong, can he stand it?

Xia Lu saw the hesitation in her heart, and smiled at her: "It's okay to suffer a little, it's better than the two of us dying one." ”

A touch of emotion flashed in Hua Weiwei's eyes.
