"Landlord, how did you do that?"

Zhao Buyu learned Xu Yuan's movements in surprise and spoke, and his words were clearly transmitted. Sensing his voice, Zhao Buyu was stunned, what kind of means is this, to be able to transmit sound in such a place that isolates any sound?

A mysterious smile appeared on Xu Yuan's face. Obviously, they don't know what science is! And Xu Yuan happens to be a high-achieving student who has received nine years of orthodox compulsory education!

That's right, although Xu Yuan may not be as genius as anyone else in terms of cultivation, but in terms of scientific knowledge, I am afraid that Xu Yuan will crush the whole world, this question, Xu Yuan can say with confidence, "I'm sorry, I'm not targeting anyone, I mean everyone here is rubbish!"

As for why Xu Yuan did not embark on the road of saving the world with science and technology, it is naturally because cultivation is the mainstream in this world, and the productive forces are still above the agricultural society, and there are no necessary conditions for the development of science.

In Xu Yuan's view, this is just a simple principle that a six-year-old child knows, transmitting sound through the vibration of an object. He just used Tian Yuan Silk as a transmission medium, and used his own aura to make an earpiece state, ensuring that his own sound waves could reach Tian Yuan Silk and transmit to the other party's ears.

Liu Shengxiang also looked at Xu Yuan with a strange face, and his smart eyes kept staring at Xu Yuan's eyes, as if he wanted to go directly to Xu Yuan's inner world through Xu Yuan's eyes, and see through what kind of monster or demon he was.

Xu Yuan noticed Liu Shengxiang's eyes, and hurriedly avoided Liu Shengxiang with some embarrassment, this subtle action was naturally captured by Liu Shengxiang, and the corners of his mouth under the veil were slightly upturned!

"This man is still shy??" Yanagi muttered in her heart.

Xu Yuan's mystery completely attracted Liu Shengxiang's attention, and at the first sight of the contact, Liu Shengxiang was keenly aware of this, just like a diamond in the black soil, which can emit a blazing brilliance in the sun.

Xu Yuan didn't expect that this game played among the children of Blue Star would bring such a big shock to everyone.

"You don't understand science!!" Xu Yuan shook his head helplessly in his heart!

Before everyone could come back to their senses and hear Xu Yuan's words clearly, a miserable howl like an abyss of hell sounded, which clearly reached everyone's ears, and they heard it very clearly, the sound was not transmitted through Tianyuan silk, but directly to everyone's ears out of thin air.

"How is that possible!!"

Isn't this an end to the spread of all sounds?

The mutation was abrupt, and a gray-black mist rose from all the rooms on the entire third floor, and many pairs of red spots lit up in it, and one after another geismus-like creatures swung out of the mist, and many black words circulated outside their bodies, floating in the air, surrounding everyone, and more and more.

Xu Yuan clearly found that the smart women in the portraits in the room were blurry for a while, and then rushed out of the paintings, turning into scantily clad beautiful women, but the pupils of their eyes were very evil red, and seeing Xu Yuan and the others was as if they had seen a large piece of delicious cheese, with saliva in their mouths, which was completely inconsistent with their appearance.

Xu Yuan found that all the women who rushed out of the paintings were some beautiful women, and what emerged from the books was a gray and black ghost-like evil thing, and their bodies were flowing with some words in the book.

To be honest, Xu Yuan is a little trembling, and things that have no substance like wandering souls and wild ghosts are the most difficult to prevent!

"Yikes!!"

Those monsters surrounded Xu Yuan and the others in the middle, screaming in unison, and the piercing sound waves frantically hit into everyone's eardrums, the sound like two pieces of rusty iron rubbing against each other, making everyone extremely uncomfortable.

Liu Shengxiang raised his eyebrows, transported his aura, and fought back with sonic power, and the violent sound waves exploded silently in the air, even causing the surrounding air to ripple in circles.

The group of monsters saw Yanagi Xiang's counterattack, and in an instant, all the sound waves hit Yanagi Xiang alone, and the violent sound waves came from all directions, without any dead ends, Yanagi Xiangxiang not only did not succeed in countering, but was shocked by the sound waves because of the resistance of Yungong.

Xu Yuan's face was solemn, according to the current situation, this group of monsters is not bound by the rules here at all, when they want you to hear the sound, you can hear it, but when they don't want you to hear it, then you can't hear even the slightest.

In other words, it is not the ability to speak that is lost, but the sense of hearing!

Liu Shengxiang staggered a few steps back, her feet were weak, and she fell to the ground with her buttocks, Xu Yuan saw that the little Lori Butterfly and the other disciple opened their mouths a few times, and hurriedly ran to support Liu Shengxiang.

Xu Yuan didn't speak, but walked quickly to Liu Shengxiang's side to protect her, and took out a high-quality healing pill from his arms.

Liu Shengxiang is the only one in the team who knows how to sonic power, if Liu Shengxiang kneels, then Xu Yuan feels that he and others are almost the same.

Liu Shengxiang was stunned for a moment, looked at the pill given by Xu Yuan and hesitated, Xu Yuan frowned and looked nervous, and forced the pill into Liu Shengxiang's hand, signaling her to hurry up and heal her injuries and protect her by herself.

Liu Shengxiang nodded slightly, knowing that this was not the time to hesitate, she lifted her veil, put the elixir in her mouth, and then began to heal.

Xu Yuan turned around to face many monsters and summoned his Yuan Shen, the only one who still had some combat power, Zhao Buyu and the disciples of Tingxiangju also stood with Xu Yuancheng in a triangle, protecting Liu Shengxiang in the middle.

How could the evil creatures let Xu Yuan and the others move, roared wildly and silently, and swarmed up one after another, surrounding everyone, their terrifying faces were revealed, and they quickly wandered around everyone. With a light suck in his mouth, Xu Yuan and the others felt that the aura in their bodies was being sucked away by those evil things.

Xu Yuan hurried to a crisis, if this group of monsters sucked away everyone's already small amount of aura, then the next thing would definitely be death without a place to be buried.

Xu Yuan, who originally just wanted to defend, did not hesitate at all, and immediately turned the defensive strategy into an offensive strategy, and with both hands, dozens of red spirit cards appeared around his body, and the flames on them flowed.

Although Xu Yuan had never dealt with illusory things, he vaguely remembered that the element of flame could somewhat restrain some evil, but the effect was not satisfactory.

"Bee Moan, Fire!!"

Xu Yuan, who was in the state of Yuan Shen, was obviously more comfortable with the control of the aura, and with a low shout, all the spirit cards flew out in all directions, bursting out clusters of flames.

"Squeak!!"

As soon as they made contact, the evil spirits erupted into a series of sharp screams.
