Infinite I Have Billions of Movie Worlds

There was a "hum" sound, which was a bit unpleasant, and spread immediately.

sonar.

It uses sound waves to detect, locate and communicate underwater targets. It is the most widely used and most important device in underwater acoustics.

They can interfere with the reception and transmission of messages by these marine organisms, so that these marine organisms behave abnormally or even die.

For humans, when the noise exceeds 50 decibels, it will affect the normal life of human beings.

Above 70 decibels, it can lead to distraction and lack of concentration, and the highest noise a person can tolerate is 155 decibels.

Any speaker with a low frequency sonar can emit up to 215 decibels of noise.

For example, underwater is equivalent to the noise level near a twin-engine F-15 fighter jet about to take off.

Biologists say sound waves above 110 decibels can make whales restless, and 180 decibels are enough to rupture a whale's eardrums.

However, the maximum power of the sonar tool in Qin Xuan's hand can be adjusted to 180 decibels!

This is a tool that can hurt people, what is not a sonar weapon?

Qin Xuan looked at this very delicate surface, and it turned into a natural silver-gray streamlined horn, and gently stroked it, just like treating his own child.

He has been in this film and television world for two years, which is not long.

For the things he took out from the mermaid world, it was more than two years, and he hadn't seen his two lovers.

Han Shengjing, you little savage girl, how are you?

Li Ruolan, after I left, are you still sleeping beautifully?

And the newly born daughter Qin Linglong, will you notice that your father has left?

Even though Qin Xuan knew that those film and television worlds were frozen in time after he left, even if he left for a long time, everything there would not change at all!

But he is not the kind of pure cultivator who is heartless.

Missing this thing, as time goes by, it becomes more and more like a cup of brewed tea.

The temperature is just right, the taste is strong...

Immediately, the pores all over the body shrank and closed, and at the same time, all the nerve endings were temporarily cut off, that is, the nerve lines that sealed the ears lost hearing.

Using such a small skill, the Beiming bodyguard was immediately reduced in scope.

Even the airtight surrounds the whole body, keeping a distance of only two inches, but the airtightness is several times higher!

At this time.

His face suddenly changed, he exhaled suddenly, and suddenly there was a thunder on the battlefield!

Lion's roar, plus sonar loudspeaker!

the first two years.

When he went to look for Wu Xingyun, the grandmother of Tianshan Mountain, he heard a lion roar at the foot of Tianshan Mountain, which temporarily stunned many martial arts practitioners, and also directly shocked some people to death!

Now two years later, the group attack range is a big skill, and the lion's roar has appeared again!

And this time, under his powerful skills, the power is even stronger than before, and the effect is even better!

Without him, because there is an extra sonar weapon horn!

Although it is said that the effect of its own is negligible, but if it is matched with the lion's roar, the special sound wave transmission method, Qin Xuan has never tried such a power, and he is not sure of its power.

But the lethality of the sound attack method that ignores the number of people in the group battle can be imagined!

Everything is ready, just wait and see!

……

"Yan'er, Ah Xuan has brought out that strange treasure.' !"

"Well, I remember what I told you before I came!"

The two women who had been prepared for a long time, saw this scene, and immediately looked at each other, and also tapped their ears to seal the acupuncture points.

Because Qin Xuan once said solemnly that the power of this baby is still unknown, and some measures need to be taken.

The measure is that he took the initiative to go to the local camp to keep a distance to avoid accidental injury.

This point is to make the sonar into a horn, which is mainly to gather sound waves, and secondly to prevent accidental injury to one's own people!

Under the city wall, Xiao Feng, Xiao Yuanshan and others saw what the two women were doing, and their faces froze.

Although I don't know the reason, they all did it, and they would definitely not go wrong in doing so, so they also blocked their hearing.

……

Suck!

In this way, he took a deep breath and gathered Qi for as long as 7 seconds!

In the end, at a speed visible to the naked eye, Qin Xuan's chest has already swelled twice out of thin air, and now he has become a big fat man!

Qin Xuan held his breath, and a ferocious killing intent flashed in his eyes!

".〃what!"
