Chapter 1090

When Chris said this, Gu Changsheng went to one side, turned on another instrument, pointed to the curve that looked like an electrocardiogram and said:

"this is the frequency of the sound wave device currently in use in our whole laboratory! He has been working since the completion of this acoustic device, but this kind of sound wave is not within the range of human hearing! "

Ouyang Feng and Duan Lei look at the screen showing the curve. Of course, this kind of curve has no meaning for them, so they don't speak, just wait for Gu Changsheng to go on.

"Although we humans can't hear the sound of the device, the sound still exists, and it will make all the researchers in our laboratory concentrate and improve our work efficiency!"

Chris took over the conversation and continued: "since entering this layer, our laboratory has never been attacked by soul body creatures. Now we have confirmed that the reason is this kind of sound wave, so we are going to modify this sound wave device to increase its frequency, so that the sound waves it emits can cover the whole

defensive fortress."

"Although we are not sure that this kind of sound wave can kill those soul creatures, at least it should be able to make us humans no longer die! And we can also try to change the frequency of this device and increase its acoustic output! "

Ouyang Feng and Duan Lei look at each other, then nod their heads together, because now they have used all the ways, but they still can't find a way to deal with this kind of creature, so they have to try Chris and Gu Changsheng's way.

They didn't expect that even the goblins and the brys were easily killed by them, but now they can't do anything about this kind of creature, which was originally the lowest level on the primordial star. Because there are basically no ordinary creatures on the primordial star, even the goblins have a large number of enhancers, and although some of them have not reached the level of enhancers, the goblins should have the technology to deal with this kind of soul body creature, so in the time of primordial star

this kind of soul creature is really the lowest creature.

It's just that their bodies are illusory, and they don't have any camps, let alone supplies, so there are no races on the primordial star to take the initiative to trouble them! But now, they have become obstacles for the Terran to pass through the endless tower, which makes Ouyang Feng very depressed! Originally, Ouyang Feng thought that his Xuanyuan sword or Qiu Jian's destructive power should be able to kill these creatures, but now the problem is that they can't show these soul creatures, let alone how to kill them.

"Chris! Dr. Gu Changsheng! You can start to refit this acoustic device now. We will give you our full support. The only requirement is to be quick! The sooner the better! "

Duan Lei said without hesitation:

"now there are still people dying in the Terran, and we don't have any way for us to find them, so it's up to you!"

"Well!"

Chris nodded and said:

"in fact, the modification is in progress now. As for the progress, I'm not sure, because it's not my field of expertise. I haven't even had much contact with it, so I can't give you a definite time when the modification will be completed!"

"But..."

Chris looked at the screen that showed the brains of the two people, pointed to it and said:

"you can carry those people who have been invaded here, see? The shadow in these two people's brains is fading away, so this kind of sound wave can also save those who have been attacked! "

"Well It's no use

Duan Lei shook his head and said: "if my guess is correct, after these two people are sent to the laboratory, the soul creatures that were originally hidden in their bodies have left, so unless we can put all ordinary people within the scope of sound wave coverage, they can continue to attack other ordinary people

!"

Hearing Duan Lei's words, Chris and Gu Changsheng were stunned at the same time. Then they understood and shook their heads together. It seems that Duan Lei's words are very reasonable, and their laboratory can't accommodate all ordinary people, so his method is really useless! "Don't worry! Now more than 100 people are working together to refit the sound wave device, and I have asked them to make a few of these sound wave devices again. Anyway, the materials consumed are not much, and even after this level, those devices don't need to be cancelled. Its function is to make people pay attention to it. In the complete works, this function can be used in peacetime! " Gu Changsheng looked at Ouyang Feng and said that the old doctor was rescued by Ouyang Feng from the research institute next to juqing city at the beginning, and then followed them all the way to the present. Moreover, because of Ouyang Feng's medicine, Gu Changsheng, who was old and frail, now has the strength of an evolutionary

, and of course his life has been prolonged a lot.Therefore, Gu Changsheng was more grateful to Ou Yangfeng. He sighed and said: "in fact, we can find more than 100 people to help us now. It all depends on the attention you paid to these researchers who are powerless. Without you, they would have died in the attack of zombies or other mutant creatures."

Ouyang Feng and Duan Lei are also secretly happy, because to tell you the truth, these researchers, when they were on Atlantis, were really useless. Like the old people and children, they were real burdens, and they could not even plant land! Fortunately, ouyangfeng and Duan Lei were both soldiers in the last days, so they didn't give up these people. On the contrary, when they were in the army, they knew their country well and attached great importance to these researchers, so they not only didn't give up these researchers, but also gave them special care! Only in this way can they survive to the present, and can they continue their technological research and development before the end of the world!! Because this acoustic device was Gu Changsheng's research project in Atlantis at the beginning, most of the researchers who later assisted Gu Changsheng came from Atlantis. It's not that the researchers on the parent star are not good, but they come from two different stars after all. Although they are all human beings, their research directions are very different!

"Good! Hurry up and let me know immediately! "

Ou Yangfeng nodded and then looked at Duan Lei:

" Leizi! You're here. I'll... "

"Good!"

Without waiting for Ouyang Feng to finish, Duan Lei nodded and said:

"you go!" Duan Lei knows that Ouyang Feng wants to continue to search for those soul body creatures. Although they seem to have found a way to deal with these guys, one reason is that they have never used this method, and they don't know the effect at all, so they can't put the future of the Terran on this acoustic device!!

And ouyangfeng can't help at all, because they don't understand this at all, so as long as Duan Lei stays here and makes a decision at the critical moment.

After leaving the laboratory, Ouyang Feng came to Mars again, where they lived. Now, as before, there are still people falling down, but others are helpless. Although all the medical teams are here, these people are not physically injured, but the soul or brain is invaded by soul creatures. Not to mention now, even in the well-equipped hospitals of the home planet or Atlantis, there is basically no effective treatment for the ethereal East and west of the soul.

After Ouyang Feng came back, he first told everyone the signs of being invaded by soul creatures, and asked them to check with each other, because now those attacked by soul creatures basically won't have any abnormalities.

Soul creatures seem to know that Terrans can strengthen themselves to defuse their attacks. Therefore, they are no longer trying to increase their death toll with the help of human mutual attacks as before, but start to lurk

After they invade the brain of a human race, they just start to invade slowly, because it is not possible to cover the brain with shadows in an instant.

So the Terrans that are attacked by soul creatures are all good before. Suddenly, they faint directly, and then If there is no other way, you will die directly in your dreams.

In fact, such an enemy is not terrible, because at least there is no pain in being killed by them! Besides, there was no obvious wound on the body, except for a look of horror and bleeding from the seven orifices With ouyangfeng's reminding, many ordinary people are found with blood in their pupils. However, because of the current situation, many ordinary people are in a panic. Many people can't sleep at night, because they are afraid that once they fall asleep, they will never wake up, so they can't be sure what the blood in this person's eyes is It's caused by lack of sleep, or it's really attacked by soul creatures!

Three days later, the death rate of ordinary people began to increase. Just in these three days, the death rate of ordinary people far exceeded the previous total, reaching 10000 people!

This is a terrible number. If we keep increasing according to this number, it won't be long before the Terran will be judged as a failure because of the excessive death number, and the whole clan will be wiped out

However, at the end of the third day, Duan Lei's voice finally came: "crazy! The acoustic device has been transformed! We will spread the sound wave to the whole defensive fortress in a moment. If you let everyone pay attention, there may be some accidents! "
