At this moment, the seventh master seemed to see the clue, and hurriedly stopped the eighth child, and then stretched out his hand, grabbed my collar, and dragged me to the coffin in one fell swoop.

When my feet left the ground, I obviously felt that the coolness of my body disappeared, my body temperature gradually rose, and I felt that my body warmed up for a while. ”

I didn't have time to respond to him, and hurriedly stretched out my hand to pull Wang Chuyi up, the cold fire on the ground was really uncomfortable, I am afraid that staying for a while longer would be a kind of torment, after Wang Chuyi was pulled up, he was also trembling, his lips were frozen purple, and he hurriedly rubbed his hands and exhaled a few breaths of hot air, and said, "This fire is really evil, it is cold." ”

As soon as the words fell, the eighth said, "It's good that it's cold, otherwise you would have been burned to death!" ”

At this time, the Seventh Master frowned, looked at the flames that were still burning on the ground, and said in a deep voice: "At this time, I am afraid that there are not a few unjust souls who died in this tomb." ”

As soon as the seventh master's voice fell, I heard a terrible shout, turned to look, and saw that the face on a square brick was suddenly distorted, and the whole face was about to be twisted into a ball, and the cry came from the man's face.

At this time, the seventh master patted Wang Chuyi's shoulder and said, "Bring your gun to me for use." ”

The seventh master rarely uses a gun on weekdays, and at this time he suddenly asked Wang Chuyi for a gun, which was really stunned, even Wang Chuyi himself did not come back to his senses, the seventh master shook his arm again, and Wang Chuyi took out a pistol and handed it to the seventh master.

After the seventh master received the gun, he raised his hand to the top of the southwest corner of the tomb is a shot, the bullet was discharged, and it hit the center of the corner accurately, just after the bullet hit there, the terrible scream stopped abruptly, not only that, but even the faces on some of the walls in the west corner disappeared.

At this time, the seventh master nodded and said, "So that's the case!" As soon as the words fell, another shot was fired at each of the other three corners of the top of the tomb, and as the bullet hit the target, the faces on the bricks of the entire tomb disappeared, and the whole tomb was calm again.

After doing all this, the seventh master returned the gun to Wang Chuyi and said, "Okay, this face mechanism is broken." ”

At this time, Wang Chuyi and I were still in a daze, surprised by the way the Seventh Master broke the mechanism, and couldn't help but ask, "Seventh Master, what's going on?" This man's face ......"

The seventh master waved his hand, stepped down from the coffin first, and said, "This is the Four Elephant Array, and in the four corners of this tomb, there is a bell, and the sound waves emitted by the vibration of this bell give us an illusion, and human faces will appear on the walls of the tomb. ”

After listening to the seventh master's words, Wang Chuyi frowned and asked, "But when we came in, we didn't hear any sound?" When did the bell ring? Why didn't you notice it at all. ”

At this time, Lao Ba's face suddenly realized, and he hurriedly said, "I know this, the sound wave generated by this bell should be a kind of infrasound wave, which is imperceptible to the hearing ability of our ears, but it is extremely harmful. ”

After the eighth child finished speaking, Wang Chuyi's faces and I changed drastically, it turned out to be infrasound, I'm afraid this is the most powerful mechanism we have encountered in the ancient tomb, it can really be said that it kills people invisibly.

The so-called infrasound wave is actually a sound wave with a frequency of less than 20 Hz (hertz), which is not easily attenuated and not easily absorbed by water and air. The wavelength of infrasonic waves is often very long, so it can bypass some large obstacles and diffraction occurs, and infrasound waves of certain frequencies are easy to resonate with human organs because they are close to or even the same as the vibration frequency of human organs, and have a strong harm to the human body, and can cause death when dangerous.

In nature, sea storms, volcanic eruptions, large meteorite landing, tsunamis, lightning and thunder, waves hitting the shore, tornadoes, earthquakes, etc. may be accompanied by the occurrence of infrasound waves.

That is to say, infrasound waves can be actively produced by human beings, but I didn't expect that thousands of years ago in the ancient civilization period, it was possible to create a bell that could produce infrasound waves, it seems that the four-cornered bell in this tomb must have been a priceless treasure at that time!

The infrasound waves emitted by this bell are extremely harmful, which can interfere with the normal function of the human nervous system and endanger human health. If it weren't for the Seventh Master's timely discovery, if this kind of bell continued to ring silently, it could make people dizzy, nauseous, vomiting, loss of balance and even mental depression.

The infrasound waves emitted by the bell are reflected back and forth in this burial chamber, producing stronger infrasound waves, and it is estimated that within half an hour we will be deaf, unconscious, insane and even dead.

No wonder this tomb is polished so smooth, and there are no furnishings in the whole tomb, only a huge coffin, it seems that the infrasound waves emitted by this bell are fully reflected, so that the tomb robbers can die invisibly, such a powerful mechanism, it is really chilling.

At this time, I also got down from the coffin, followed behind the seventh master to check the lid of the coffin, and looked at the posture of the seventh master, it is estimated that the coffin is about to be opened.

While inspecting the coffin, the seventh master said, "This time I met the sound wave for the second time, I remember fifteen years ago, when I first entered the industry, I followed the older generation of inverted people into the ancient tomb, when passing through an ancient cemetery palace, because I had little experience, I walked a little slower, fell behind, followed a wounded team member, walked forward in the dark, when I passed through the underground palace, came to a tomb, found that everyone was standing motionless in the tomb, everyone maintained a posture of walking forward, The miner's lamp in his hand was still on, and even the expressions on his faces did not change, and some of them were still smiling, but they were all dead, almost all of them died in an instant, if it wasn't for the experienced veteran team member who saw the clue and stopped me from entering the tomb in time, I'm afraid I should have stayed in that ancient tomb now. ”

As soon as the seventh master's voice fell, Wang Chuyi's voice came from the southeast corner, I turned to look, only to see that she had successfully lit the candle, I looked at the flame burning on the candle, which slightly relieved the tense nerves, it seems that the mechanism of this tomb has really been broken by the seventh master, I have to say that the rich experience of the seventh master has really saved our lives.

When Wang Chuyi came to us, the seventh master motioned for us to take a step back, he took out his saber, quickly and accurately inserted the blade into the gap of the coffin, and then circled the coffin, and used the blade to remove the mud linked between the coffin and the lid, and then turned his head to look at the eighth child, and said in a low voice, "I'm ready to open the coffin, are you sure you want to be here?" ”

Lao Ba's face was a little ugly, but he didn't dare to break the rules, so he took five or six steps back and raised his hand to signal us to continue.

At this time, the seventh master reached out and touched the lid of the coffin, and said in a low voice, "This soul-leaving twin coffin has a complex structure, there must be two coffins in the coffin, these two coffins are true and one false, and there must be two people in the real coffin, a man and a woman." ”

As soon as the seventh master's voice fell, Wang Chuyi opened his mouth and asked, "This man and woman can't be true or false, right?" ”

The Seventh Master shook his head and said, "Of course not, the two corpses will never be fake, but if these two coffins are opened wrongly, the result will be ......."

Wang Chuyi sighed and said, "Isn't the result just that the fish is dead and the net is broken?" Let's finish playing. ”

The Seventh Master nodded and said, "One of these fake coffins has a mechanism connected to the entire tomb, once touched, the tomb will collapse in an instant, burying everything here completely, remember the soil slope of Aoshan Mountain seven years ago?" ”

"Aoshan Tupo!" I exclaimed, the soil slope of Ao Mountain was a big event that shocked the entire inverted bucket world, at that time there was a no-man's land in Ao Mountain, the main vein of the Qinling Mountains, there was no vegetation cover in it, it was a high soil slope, and below the mound was a thousand-year-old mausoleum, I remember that the entire soil slope suddenly collapsed, the ground sank more than ten meters, the whole Ao Mountain trembled, everyone thought it was an earthquake, and they fled for their lives, only a very small number of people in the inverted bucket world knew, that was a team of people and horses went to the tomb to fight upside down, accidentally touched the mechanism, caused the entire ancient tomb to collapse almost instantly, which is why there is such a big movement.

Afterwards, everyone kept speculating, what kind of mechanism did this team encounter? Some people say that they came across a tomb door that could not be opened, and they were forced to use it*, and due to the excessive use, the ancient tomb collapsed.

It is also said that they encountered the self-destruction mechanism in the ancient tomb, and the whole team was buried in the ancient tomb.

I looked at the Seventh Master with a look of surprise and asked, "Seventh Master, do you mean to say that the people in the ancient tomb were ...... because they staggered the twin coffins of the Soul Leaving Sect."

The Seventh Master nodded, and said, "As far as I know, these people are all old rivers and lakes in the inverted fighting world, and they are all good players, and they will never use this kind of indiscriminate means, and the biggest possibility is that they ran into the twin coffins of the souls and lifted the wrong coffin board, so they died under the ancient tomb." ”

Hearing this, we couldn't help but gasp, it seems that this soul twin coffin is really powerful, no wonder it can rank second among the top ten main coffins, it seems that if we really open the wrong coffin, I am afraid that the mysterious ancient city above our heads will disappear from the earth, and the entire Wawu Mountain will shake, and it is estimated that even the town where we lived before may be affected.

The seventh master had a serious expression on his face, looking at the coffin lid that had been stripped of the mud, and his face also leaked a look of embarrassment.

This time, I kind of figured it out, why the people who are fighting backwards will turn around and leave as long as they see the twin coffins of the souls, in fact, it is not the curse inside, the head is lowered, and the poisonous Gu is powerful, but because of this deadly organ.
