At this time, the zombie swarm has already filled up the southern branch base, and even the material warehouse in the center is unavoidable. People who are not close to these zombies at high altitudes have complicated emotions, because they stand high and can see far. Having a panoramic view of the Southern Department base, one can deeply understand the critical nature of the current situation.
He Feng and others looked at Chu Han nervously. The zombie tide had reached the most difficult moment to fight against. What trump cards did Chu Han have to make a comeback
Snapped!
A soft sound.
Chu Han's finger just flipped the switch of the loudspeaker, and this subtle sound also caused everyone in the room to shift their eyes and look at this big guy who was invented by Master Chen and specially sent to the front line of the battlefield.
With this thing alone, they can make a comeback
Many people began to doubt it from the bottom of their hearts, not to mention that Gao Shaohui thought it was useless from beginning to end. Chu Han also just got this thing, and no one knew the effect.
Just when Chu Han pressed the start button, an extremely subtle sound wave came from the speaker, 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 heard it, but the strange thing was that the sound was obviously very loud, but they didn't hear it clearly.
It's a bit like a dolphin's cry, and a bit like a baby's cry. It's so weird!
Several people in the command room looked confused. They didn't understand how this extremely weird voice would help them in this battle.
"Can you hear clearly, but not clearly?" Chu Han said with a smile at this time.
He Feng nodded and replied: "Intermittently."
"How come I hear a melody?" Gao Shaohui was surprised at this time: "It's not intermittent, but a continuous, super unpleasant melody!"
"I really want to be different from you." Another member of the staff said with a horrified expression: "I only heard a scream every once in a while."
Suddenly everyone in the room looked at each other with extremely ugly expressions. Everyone heard a different sound. Could it be that they had seen a ghost
Chu Han was not surprised: "It's normal. The sound frequency that ordinary people can hear is between 20 Hz and 20,000 Hz. 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 in a much wider range than us, so he can hear all the sounds clearly."
After listening to Chu Han's explanation, everyone understood, but there was still one most critical issue they didn't understand.
Jiang Tianqing immediately asked: "Let's not understand anything about Hertz frequency. I just want to know what this has to do with the zombie tide?"
Chu Han's eyes were bright: "You should know that zombies generally have no vision, but their hearing is extremely sharp, right?"
As soon as these words came out, the command room suddenly became extremely quiet. Smart people had already drawn conclusions from the known clues. For example, He Feng was already looking out impatiently at this time, but he had not yet figured it out. People such as Gao Shaohui were still scratching their heads and staring at Chu Han.
The frequency range of sounds that zombies can hear is obviously different from that of humans!
"Oh my God!" A member of the staff shouted at this time, shouting with great excitement: "Heshang is really a genius! Look outside!"
Almost all the members of the staff were extremely smart, so they were the ones who understood it the quickest after He Feng. The few remaining people in the command room subconsciously shifted their attention again after hearing this shout. On top of the battle below.
At this time, a scene that surprised everyone and surprised Chu Han happened right in front of their eyes!
Of the more than seven million zombies that crowded the entire Southern Department base, close to five million seemed to be frozen in place by magic. It was even more obvious from above, with squirming black spots everywhere just staying in place. , like statues.
This sound wave can actually achieve such an effect!
Although the specific principle is estimated to be understood only by He Shang, it does not affect the few people in the command room to seize the opportunity instantly.
"All attack! These zombies can't move!" He Feng immediately ordered over the loudspeaker.
And when these five million zombies were unable to move, the members of the Wolf Fang Chapter who were almost submerged in the sea of corpses finally resurfaced.
Although their number has dropped significantly, and everyone's clothes have been scratched by zombies, and many people's skin is full of zombie scratches, but the moment the opportunity arises, the madness of the Wolf Fang Chapter The counterattack has already begun!
"Kill! Blast the zombies' heads!" shouted a team leader among the recruits, and quickly and hard hit the heads of the zombies that surrounded him.
The rest of them all grasped their weapons again and started killing the zombies around them.
No matter how many there are, the immobile zombies are no different from whack-a-mole, and it even saves them the time to fight with them. They only need to raise the weapon and then drop it, and so on.
So in a very short period of time, the zombies that swarmed into the base to cause trouble fell down in large numbers and were spread on the ground to become the latest carpet of the Southern Department base. The roads that were blocked by the crowds of zombies, Gradually, gaps began to appear.
After He Feng issued the order, he quickly discovered other situations at the scene: "No! These are low-level zombies, and there are two million zombies above level five. This sound wave is only effective against low-level zombies below level five. The strongest effect.”
"The situation of the three teams on the high wall has not improved at all, and the fighting is still fierce." Jiang Tianqing also immediately added: "Those are high-level zombie groups, all of which have exceeded the seventh level."
The level of the five million zombies that cannot move does not exceed level five. Among the remaining two million zombies, one million are slow and seem to be struggling for something. They have just passed level five or are Zombies in the late sixth level are embedded in every corner of the base.
The last million were not affected too much and were still in the frantic attack. They were the group that the third team faced, and all of them had exceeded the seventh level!
"Firing team, attack high-level zombies." He Feng immediately issued the latest order.
In fact, he didn't need to say anything. At this time, all the members of the shooting team had already begun to take aim. The target was the slow-moving zombies among the zombies. Whether it was in terms of size or current situation, they could easily distinguish them. These are the offensive targets.
"Great! There are only one million zombies above level 7 left." Jiang Tianqing was overjoyed, but just after he said this, his expression suddenly changed and his face turned pale as paper: "High-level zombies above level 7 There’s still one million?!”
