"Infrasonic attack? Can sound waves attack people? Zhang Xiaojuan's mouth was dry, and she leaned on Xiao Yu's shoulder, "Yu, I'm thirsty, come with some warm water." ”

Xiao Yu pointed his finger at Zhang Xiaojuan's mouth, "Child, is it enough?" Not enough to add more. ”

"But we didn't hear anything just now, did we?" Han Rui raised her face curiously.

Xu also divided the rest of the medicine equally among everyone, "The frequency of infrasound waves is less than 20 Hz, and sound waves in this frequency range are difficult to be heard by humans. ”

"Although inaudible, strong infrasound waves can cause hearing loss and even permanent deafness in humans and animals."

Cheng Mofan, who escaped from the death line, had palpitations, and hugged his strong head for comfort, "But just now, not only my ears, but all the internal organs in my body were torn and hurt like they were broken." ”

"The frequency of infrasound waves will resonate with human organs, and sound waves can completely destroy the internal organs of the human body when they reach a certain intensity."

"Even the failure of the radio and chandelier just now, it was the sound waves that resonated with these devices that caused the damage."

Xu Yi smiled faintly and opened Teacher Xu's small class for a few curious babies.

The curious babies listened with relish, and their eyes flashed with the clarity of a college student.

"I see, no wonder I feel like my waist hurts." Zhang Xiaojuan drank a stomach full of water, and her state was almost recovered.

He stopped talking for a while, and finally couldn't help but ask quietly, "What does the sheep village march mean?" Is there any special magic spell? After listening to this song, I immediately felt better. ”

"If this song is so godly, I will sing it three times when I get up."

"Put the Pleasant Goat to the head of my bed when I sleep."

Xu Yi's expression was calm, "High-intensity music can mask infrasound waves to a certain extent, thereby reducing its uncomfortable impact on people." ”

"The player is picked up, only this song."

"Including the medicine I gave you just now, they are all drugs that dilate blood vessels and calm nerves."

Everyone: "......"

I misunderstood, and I thought there was some magic in Sheep Village.

Compared with everyone's ease, Yang Zhenhua, who was in the laboratory separated by a few walls, turned pale and slammed the water glass on the table to the ground.

The infrasonic jammer, a secret weapon he had worked on for several years, was cracked by this group of people so easily?

After being reborn, he has top-notch R&D resources, why was he chased by these little-known people and defeated again and again?

"Originally, I wanted to keep you alive, but now, I've changed my mind."

Yang Zhenhua stared at the monitoring screen, the muscles at the corners of his mouth twitching uncontrollably.

……

After a short rest, Lu Sheng and the others finally found a hidden underground passage under the guidance of Zhuangzhuang.

In the face of the dense zombie guards, Lu Sheng was like a college student brushing the kindergarten alone, effortlessly cleaning up the unlucky zombies blocking the road with sparks and lightning all the way.

The originally crowded underground passage was quickly opened up by Lu Sheng as a wide road.

The remains of zombies piled up on the ground were all collected by Sun Tiantian and other intimate helpers.

"I knew there was such a good place, what kind of zombies are we still killing outside." Zhang Xiaojuan manipulated the little clay figure to dig the crystal nucleus, "There are many monsters here, and the purity of the crystal nucleus is high, it is really a warehouse of conscience." ”

Just as Lu Sheng and his party rushed towards the depths of the passage, the lights in the corridor suddenly flickered a few times.

Then everyone's eyes went dark.

The secluded underground passage plunges into endless darkness.

A few people had just pulled out their lights when a series of footsteps and shrill roars suddenly came.

"Ho-ho!"

The pungent smell of formalin potion hit his face, and a strong air flow suddenly hit the right rear position of Lu Sheng.

Lu Sheng sensitively avoided sideways, and turned around to meet a pair of eyes as bright as light bulbs.

"Lu Sheng, it has nine levels! I've reached the level of the Corpse King! "Zhuang Zhuang was so nervous that his voice broke.

This zombie has been soaked in formalin liquid for a while, and the skin on his face is soft and white, and he can't see his facial features. The surface of the body was all surrounded by reinforced metal, and the two arms were replaced with mechanical arms like Xiao Ning.
