Chapter 1626 Frequency

At this time, the group of zombies had already filled the South Office base, and even the material warehouse in the center was unavoidable. People who did not face these zombies up close had mixed feelings because they stood tall and saw far away. Taking a panoramic view of the South Department base, one can better understand the crisis of the current situation.

He Feng and the others looked at Chu Han nervously. The tide of corpses has reached the most difficult moment to fight. What cards does Chu Han have to turn the tables?

Snapped!

There was a soft sound.

Chu Han's fingers just flipped the switch of the loudspeaker, and this slight sound made everyone in the room look away, looking at this big guy who was specially sent to the front line of the battlefield by Young Master Chen.

With this thing alone, they can come back?

Many people began to doubt from the bottom of their hearts, not to mention that Gao Shaohui thought it was useless from the beginning to the end, and Chu Han had just obtained this thing, so no one knew how effective it would be.

It's just that when Chu Han pressed the start button, an extremely subtle sound wave came out from the stereo, and through the speakers in the command room, this sound wave was transmitted to every corner of the base.

After the sound was infinitely amplified, many people could hear it, but it was strange that the sound was already very loud, but they couldn't hear it clearly.

It's a bit like the cry of a dolphin, and it's a bit like a baby crying, so weird!

Several people in the command room were puzzled, wondering how this weird voice would help them in this battle?

"Can you hear clearly, but can't you hear clearly?" Chu Han smiled at this time.

He Feng nodded and replied, "On and off."

"Why did I hear a melody?" Gao Shaohui said in surprise at this time: "It's not intermittent, but continuous, super ugly melody!"

"I really want to be different from you." Another member of the staff department said with a horrified expression, "I only hear a scream every once in a while."

Immediately, everyone in the room looked at each other in dismay, their expressions were extremely ugly, everyone heard different voices, could it be that they have seen a ghost?

Chu Han was not surprised: "It's normal. The sound frequency that ordinary people can hear is between 20 Hz and 2000 Hz, while the range of new humans will expand, and the range will become wider as the level increases. , Gao Shaohui has a natural advantage, he can hear frequencies much wider than ours, so he can hear all the sounds right now."

After listening to Chu Han's explanation, everyone understood, but there was still one most crucial question that they didn't understand.

Jiang Tianqing immediately asked: "Let's not talk about the Hertz frequency or anything. I didn't understand any of it. I just want to know what this has to do with the corpse tide?"

Chu Han's eyes were burning like a torch: "You should know that zombies generally have no vision, but their hearing is extremely keen, right?"

As soon as these words came out, the command room suddenly became extremely quiet. Smart people had already drawn conclusions from known clues. People like Gao Shaohui were still scratching their heads and staring at Chu Han.

The range of sound frequencies that zombies can hear is obviously different from that of humans!

"My God!" A member of the staff department shouted at this time, excitedly shouting: "He Shang is really a genius! Look outside!"

The members of the staff department are almost all extremely smart, so they are also the ones who understood the quickest after He Feng, and the rest of the few people in the command room subconsciously shifted their attention again after hearing the yell On to the battle below.

But at this time, a scene that surprised everyone and surprised Chu Han happened right in front of their eyes!

Of the more than 7 million zombies that crowded the entire Nanshu base, nearly 5 million remained motionless as if they were held in place by magic. It was even more obvious when viewed from above. The wriggling black spots just stayed in place. , like a statue.

This sound wave can achieve such an effect!

Although the specific principle is estimated to be understood only by Heshang,

But it didn't affect the few people in the command room to seize the opportunity instantly.

"All attack! These zombies can't move!" He Feng immediately ordered through the loudspeaker.

And when the five million zombies were unable to move, the members of the Spike Corps, who had been almost submerged in the sea of ​​corpses, finally re-emerged.

Although their number has dropped significantly, and everyone's clothes have long been scratched by zombies, and many people's skin is full of zombie scratches, but the moment the opportunity appeared, the madness of the Wolf Fang Group The counterattack has already begun!

"Kill! Blast the heads of the zombies!" A squad leader among the recruits yelled, slamming the heads of the zombies that surrounded him fiercely.

The rest of the people also gripped their weapons tightly again, killing the zombies around them.

No matter how many immobile zombies there are, they are no different from whack-a-mole, and it even saves them the time of fighting with them. They only need to raise their weapons and smash them down, and so on.

So in a very short period of time, those zombie groups that poured into the base to cause chaos fell down in large numbers, and spread on the ground to become the latest carpet of the Nanshu base. The roads that were crowded and blocked by the zombie groups Also gradually began to have a gap.

After He Feng gave the order, he soon discovered other situations on the scene: "No! These are all low-level zombies, and there are two million zombies that have passed the fifth level. This sound wave is only effective for low-level zombies below the fifth level." The strongest effect."

"The situation of the three teams on the high wall has not improved, and the battle is still fierce." Jiang Tianqing also immediately added: "Those are all high-level zombie groups, and all of them have passed the seventh level."

The group of five million zombies who could not move were all at the fifth rank. Among the remaining two million zombies, one million moved slowly and seemed to be struggling for something. Whether they had just passed the fifth rank or the sixth rank Zombies in the late stage are interspersed in every corner of the base.

The last one million has not been affected too much, and is still in the frantic attack. It is the group that the third team is facing, and all of them have passed the seventh rank!

"Shooting team, attack high-level zombies." He Feng immediately issued the latest order.

In fact, he doesn't need to say much, all members of the shooting team at this time have already started aiming, and the targets are those slow-moving zombies in the zombie group. No matter in terms of size or current situation, they can easily distinguish These are the targets of the attack.

"Great! There are only one million zombies above the seventh rank." Jiang Tianqing was overjoyed, but just after he finished speaking, his expression suddenly changed to pale as paper: "The high-ranking zombies over the seventh rank There is still a million?!"

Today is still a change
