Chapter 1626: frequency

At this time, the zombie group has filled the South Office base, and even the most central material warehouse is inevitable. Those who do not face these zombies at a high place are in a complicated mood because they stand tall and look far. The panoramic view of the South Base will be fully visible and the situation will be more acute.
He Feng and others looked at Chu Han nervously. The corpse tide has reached the most difficult time to confront. What other cards can Chu Han have to turn over?
Snapped!
A soft bang.
Chu Han’s fingers directly swayed the switch of the big sound, and this subtle sound also made the eyes of the people in the house shift their eyes and looked at the big guy who was specially sent by Chen Shaoye to the front line of the battlefield.
With this gadget alone, can they turn over?
Many people have begun to doubt from the bottom of their hearts, let alone Gao Shaohui thinks that it is useless from beginning to end. Chu Han is just getting this thing, and no one knows the effect.
Only when Chu Han opened the button, an extremely fine sound wave was heard from the sound. Through the speaker in the command room, this sound wave was transmitted to every corner of the base.
After the sound was infinitely magnified, many people also heard it. It was just a strange thing. The voice was very loud, but they didn’t really listen.
It's a bit like a dolphin call, and it's a bit like a baby crying, it's weird!
How many people in the command room looked inexplicable, and did not understand how this weird voice helped their battle?
"Is it clear and inaudible?" Chu Han laughed at this time.
He Feng nodded and answered: "Intermittent."

How do I hear a melody?
Gao Shaohui was surprised at this time:
It’s not intermittent, it’s a continual, super ugly melody!

"I want to be different from you." Another member of the staff was dismayed and said, "I only heard a scream every so often."
The people in the room suddenly looked at each other, and the face was ugly. Everyone heard different voices. Could it be that they couldn’t be a ghost?
Chu Han is not surprised: "It is normal. Generally, the frequency of sounds that ordinary people can hear is between 20 Hz and 20,000 Hz, while the range of new humans will expand, and the wider the range as the level increases. Gao Shaohui has a natural advantage. He can hear a lot more than ours, so I can hear all the sounds at the moment."
Listening to Chu Han’s explanation, everyone understands it, but there is still one of the most critical issues that is not understood.
Jiang Tianqing immediately asked: "I didn't understand what the frequency of Hertz was, I didn't understand it. I wanted to know that this has something to do with the corpse tide?"
Chu Han’s eyes are like a torch:
You should know that zombies are generally without vision, and the hearing is sharp and incomparable?

When the words came out, the command room suddenly became extremely quiet. The intelligent people had drawn conclusions from the known clues. For example, He Feng was already eager to look outside, but did not want to understand. People such as Gao Shaohui are still holding their heads and Chu Han big eyes and small eyes.
The frequency range of sounds that zombies can hear is obviously different from humans!
"Scorpio!" At this time, a member of the staff shouted and excitedly shouted: "He is really a genius! You look outside!"
The members of the staff are almost always smart, so they are the ones who know the fastest after He Feng. The rest of the people in the command room are subconsciously shifting their attention after hearing this scream. Going to the battle below.
At this time, the scene that made everyone unexpected, and also surprised Chu Han, happened in front of their eyes!
More than seven million zombies packed in the entire South Base, nearly five million in number seems to be fixed by the magic, generally still, from the top, it is more obvious, the creeping black spots everywhere stay in place Like a statue.
This sound wave can reach such an effect!
Although the specific principle is estimated to be only understandable, it does not affect the chances of several people in the current command room.
"All the offense! These zombies can't move!" He Feng immediately ordered it in the speaker.
And when the five million zombies couldn't move, the members of the Spike Wars, which were almost drowned in the corpse, finally re-emerged.
Although their numbers have dropped significantly, and everyone’s clothes have been smashed by zombies, many people’s skin is full of zombie scratches, but at the moment of the opportunity, the madness of the fangs The counterattack has already begun!
"Kill! Explode the head of the zombie!" The captain of a recruit was shouting, and the zombie heads surrounded by him were rushing and slamming.
The rest of the people also regained their weapons and smothered the zombies around them.
Even if there are more zombies that can’t move, it’s no different from playing the hamsters. It even saves them the time they spend fighting with them. They just need to raise their arms and then squat, and so on.
So in a very short period of time, the masses of zombies that rushed into the bases were piled up in large numbers, and they were laid on the ground to become the latest carpets of the South Base, which were crowded by zombies and blocked the roads. Gradually began to have gaps.
After he issued the order, He Feng quickly discovered other situations on the scene: "No! These are low-level zombies, and there are two million zombies over the fifth-order. This sound wave is only for low-level zombies below the fifth order. The strongest effect."
"The situation of the three teams on the high wall has not improved, and the battle is still very intense." Jiang Tianqing also immediately added: "Those are high-level zombies, all of which exceed seven orders."
The five million zombies that can't move are no more than five orders. Among the remaining two million zombies, one million of them are slow to seem to be struggling. They are just after the fifth order or The zombies in the late sixth stage are worn and inserted in all corners of the base.
There is still one last million that has not been affected too much. It is still in the midst of a crazy attack. It is the group that the three teams face, and the rank is more than seven orders!
"The shooting team, attacking high-level zombies." He Feng immediately issued the latest order.
In fact, he didn't need to say more. At this time, all the members of the shooting team have already started to aim. The target is the zombies who are slow in the zombies. Whether it is from the body or the current situation, they can easily separate them. These are the offensive goals.
"That's great! The rest is only one million zombies above the seventh order." Jiang Tianqing was overjoyed, but just after he said this, his expression suddenly changed pale as paper: "More than seven-order high-level zombies There is still a million?!"
