The walls were full of smoke and dust, flesh and blood were blurred, as if they had just been bombed, screams, cries, and panicked crowds everywhere.

Those who were lucky enough not to die quickly retreated to open up the distance, their eyes full of horror.

Li Chaoyuan's position, on the second city wall not far from here, looking at the entire row of display screens in front of him that was instantly extinguished, Li Chaoyuan was stunned for a while, but he didn't react.

"Roar! Keep yelling at me! After seeing that this trick worked, Wang Shengli walked back and forth with a little smugness, and commanded loudly.

With the repeated sonic bombardment, there were fewer and fewer people on the city wall, until in the end only those automatic weapon systems remained, but these automatic weapon systems did not last long, and they were broken and destroyed under the bombardment of sound waves.

However, fortunately, the number of mutated creatures that Wang Shengli can personally command is limited, and if all the mutated creatures are like Wang Shengli personally commanding, this first wall will soon collapse.

Looking at the gap that appeared on the first city wall on the screen, Li Chaoyuan's face turned pale: "Order the engineering department to repair it for me and fill the gap!" ”

Don't look at the children of the bigwigs in the security zone of the capital who are drunk and dreaming all day long, but those bigwigs are all self-disciplined and very restrained, and in the more than two years of training in the last days, the ability to deal with emergencies and make emergency responses to the situation is very strong.

The cooperation and work efficiency of the various departments below are also very high, so after Li Chaoyuan issued the order, engineering vehicles appeared one after another and began to repair the gap.

But most of the people on those engineering vehicles were ordinary people, and under the sonic attack, they were almost powerless, and many people died tragically on the spot.

More than half of the casualties were killed and injured in one photo, causing the rest of the personnel to run away after dropping the engineering equipment.

The reason why sonic attacks can achieve such great results is fundamentally different from other attacks.

The energy shield can block physical attacks such as bullets and cannonballs, as well as energy attacks of other attributes, but it cannot block the spread of sound.

Since the sound can travel in, it proves that the sonic attack is effective, so Wang Shengli tried it, and in order to achieve the effect he wanted, he made a sonic attack similar to a loudspeaker.

The effect of the sonic attack is significant, but there is also an obvious disadvantage, that is, since the energy shield has a small barrier to the sonic attack, the energy consumption of the sonic attack to the energy shield is also small, so small that it is almost negligible.

And this is not a big deal for Wang Shengli, he didn't plan to break the energy shield with a few attacks, he has already determined that if he wants to break this energy shield, he must come by himself, but he can't break it casually, he needs to wait for time, and it needs to be consumed.

And before breaking the energy shield, make some trouble for the enemy, if you can scare the enemy's courage, it is better, and when the energy shield is broken, it will be a one-sided slaughter.

Looking at the engineering personnel who had escaped, Li Chaoyuan scolded: "Waste! It's all rubbish! ”

Then he looked at the staff officer: "Quickly find a way for me to stop the other party's sonic attack, I remember that we seem to have a similar sonic attack!" ”

The staff officer immediately searched on the tablet, and soon there were results, and the staff officer was first happy: "Found it!" ”

But immediately cried again: "But this thing seems to be only useful for zombies!" ”

Li Chaoyuan didn't care: "It's right to be useful to zombies, but it can't be dealt with against that monster!" ”

The monster in Li Chaoyuan's mouth naturally said that Wang Shengli had won the victory, and Wang Shengli once again commanded the mutated creatures at this time, sending out a sonic bombardment towards the safety zone.

But at this moment, a sharp and piercing voice came, Wang Shengli frowned when he heard it, and was a little irritable: "What kind of sound is this?" ”

As soon as he finished talking to himself, Wang Shengli found out that something was wrong, his army of mutant creatures was chaotic at this time, and many low-level mutant creatures had begun to attack indiscriminately.

And those high-level mutant creatures also seemed restless, and the twenty Roshan didn't listen to his command very much, and the weapons in their hands were waved indiscriminately, and they could no longer complete the damage to the energy shield.

The "hum" sound was louder, so big that Wang Shengli felt irritable, so big that Roshan was no longer out of control, and he acted recklessly, and began to slaughter the mutant beasts around him frantically.

Hearing this voice, Wang Shengli suddenly remembered a woman, a woman in red pajamas, and the reason why he remembered this woman was because this woman had something to do with what Wang Shengli was experiencing now.

This woman is He Xianxian, Wang Shengli remembers that he hadn't awakened yet, he didn't have copper and copper at the beginning, and when he was forcibly dragged to Quancheng, when he was leaving, the important strategic materials he was given were sonic grenades.

At that time, the technology of sonic grenades was not yet proficient, and it could only affect low-level zombies, but the effect was very good!

Later, under Jinling City, an improved version of the sonic missile was also used, which could deal with some high-level mutant creatures.

But after He Xianxian was slapped away by Wang Shengli, the sonic weapons against mutated creatures disappeared from then on, but what I didn't expect was that today I re-encountered sonic weapons that could affect mutated creatures here.

Seeing that the army of mutant creatures was in chaos, Li Chaoyuan shouted: "Increase the power output, and let the engineering department go up again, you must repair the city wall for me!" ”

"Yes!" A staff officer hurried away.

Another staff officer hurriedly arrived again: "Report to the chief, news has come from the Wu family, the missile group attack is coming soon!" ”

"Good!" Li Chaoyuan's face finally showed excitement, and he high-fived and shouted: "Quickly cut the picture!" ”

Soon the display showed dozens of missiles dragging bright red tails towards the army of mutant creatures on the outskirts of the capital.

Under the influence of the sound waves, the entire army of mutant creatures has been chaotic, although the high-level mutant creature leaders have not been affected, although they still listen to the king's victory, but they can no longer control their subordinates.

Wang Shengli was also trying his best to control the army of mutant creatures at this time, and he didn't want the army that he had managed to pull up to collapse in chaos.

Just when Wang Shengli was working hard, he suddenly felt a palpitation, and felt that something bad was about to happen, so he immediately looked around, but there were mutated creatures as far as his eyes could see, and there was nothing that could make his heart palpitate.

At this moment, there was a roar in the sky, Wang Shengli couldn't help but look up, it doesn't matter if he doesn't look at it, he was startled when he saw it, huge bombs fell from the sky, and there were dozens of roughly estimated numbers, Wang Shengli immediately shouted: "Air defense!" Air defence! Disperse! Disperse! ”

It's a pity that it's useless at all, the army of mutant creatures is in chaos, and there is no one who listens to the command, Wang Shengli can only watch, dozens of missiles rush into the army of mutant creatures!
