Overclocking warrior in American comics

boom!

boom!

boom!

Three loud bangs were heard on the road behind everyone, and there were also the roars and roars of animals, which made everyone's hair stand on end. The nine people in Team Z turned their heads to look curiously, and their expressions instantly became stiff.

What appeared in front of the nine people was Emperor Babu, three giant bird-catching spiders of more than ten meters with orange fur and flashing their fangs at everyone.

When the three emperor babu lit up their stinging fangs, they also made a low hissing sound, and did not attack humans immediately.

Isabel, O'Neill and others looked at each other and couldn't figure out why, but this did not prevent them from approaching the Skywalker infantry fighting vehicle.

Halfway through the run, Ree, an Australian who had seen tarantulas preying on insects, remembered the past, suddenly realized, clapped his legs and shouted, "I know why they don't attack us!"

"Why?"*2

Hearing this, the curious Sol and Janis couldn't help but pause in their steps and asked curiously.

"Because we are on someone else's territory," Rei said matter-of-factly.

"Other people's territory?" Hearing this, Karl stopped and turned around and said in surprise.

"Spiders live alone, and they will kill each other when living in groups, and they will only make such warning movements when they are on other people's territory," Rui said with a serious face.

After hearing this, except for Li Minyu and Chen Huiyu, who were still approaching the Skywalker infantry fighting vehicle, the other six people stopped and turned around to stare at the three emperors who were still roaring. Babu.

"If this is true -" O'Neill had just started to say it, Athena took the next sentence, "Then what are you afraid of such a powerful monster?"

"And it's an existence that can't defeat even three giant spiders," Janice added, but unfortunately her wording was poor, which ruined the atmosphere.

Isabel stopped and said slowly, "It's a bat. Only bats in the animal world can receive this kind of sound wave. They can distinguish the warning of sound waves."

"how is this possible--"

Karl retorted. Before she could finish her words, the holographic next-generation alt watch on her hand made a crazy warning sound. She couldn't help being surprised and pressed the play button.

"Warning, high-pitched ultrasonic waves have been detected, please activate defensive measures quickly!"

"Warning, high-pitched ultrasonic waves have been detected, please activate defensive measures quickly!"

"Warning, high-pitched ultrasonic waves have been detected, please activate defensive measures quickly!"

"Oh shit, I was really predicted by you, fuck!"

Karl was shocked, but he did not stop the movement of his hands. He did not hesitate to turn on the sound wave absorption pendant of the alt tactical suit. The other people also turned on the sound wave absorption pendant. Li Minyu and Chen Huiyu who arrived at the tank also followed. The sound absorbing pendant is turned on.

The black soldiers who only wore ordinary body armor were miserable. They were completely unprepared. They even saw that the three Emperor Babu did not attack them. They also drove the als tank and pointed the tank at the three Emperor Babu. The shells were not loaded yet. I saw a burst of low-decibel ultrasound.

When the pressure of the sound wave propagated by ultrasonic vibration in the liquid reaches one atmospheric pressure, its power density is 035w/c. At this time, the peak pressure of the ultrasonic sound wave can reach vacuum or negative pressure, but in fact there is no negative pressure, so there is a A great pressure breaks the liquid molecules into holes and cavitation nuclei. This cavity is very close to a vacuum. It ruptures when the reverse ultrasonic pressure reaches its maximum. The strong impact caused by the rupture knocks off the dirt on the surface of the object.

This shock wave phenomenon caused by the collapse of countless small cavitation bubbles is called "cavitation". Sound intensity that is too small cannot produce cavitation effect.
