This strange sound is actually the ultrasonic attack of the bloodthirsty king bat, which can cause creatures within a certain range to lose their attack power or die after hundreds of meters.

Some people may ask, why didn't the bloodthirsty king bat use this trick to deal with the defenders on the wall in the first place? Have to wait until now to use it?

That's because this ultrasonic attack does not distinguish between enemy and us, and it will also harm its mutant blood bats. The bloodthirsty king bat didn't want to use this ability, but it didn't expect that its subordinates were killed, so it was forced to personally. Attack the wall...

The elite blood bats around the bloodthirsty king bats saw significant effects of ultrasonic attacks, and they were also scattered around the bloodthirsty king bats, and then opened their mouths to launch sonic attacks toward the city wall to assist the bloodthirsty king bats.

With the assistance of the elite blood bats, the attacks of the bloodthirsty king bats were even more terrifying. The defenders on the city wall were tortured to death by this sound wave. They had no resistance at all. The soldiers clung to their ears and collapsed on the ground. Someone was killed by ultrasound...

Lu Jun also heard this strange sound. He knew that this was the bloodthirsty king bat's own ability, but he, Ruan Bing and Xiaowan were all supernatural beings, and they had a certain ability to resist this kind of sound. It's just that it will be very hard to be shaken to death.

But Ruan Xue and the guards of the Blackstone Consortium were not so good. They were all ordinary people and had no special abilities. They could only grit their teeth and endure the torment of this sound.

Fortunately, the B1 section of the city wall they were on was located on the edge, and the sound wave attack they suffered was not as severe as the middle of the city wall, and they could survive for a while.

However, this is not a solution. If the bloodthirsty king bats are allowed to attack, they will die sooner or later...

"Quick! Try if you can shoot it down!" After seeing most of the people on the wall in trouble, the Lu Army picked up a rifle on the ground and said to Ruan Bing on the side.

Ruan Bing nodded, holding the soul lamp in his left hand, and a soul fire quickly condensed in his right hand, and threw it straight to the position of the bloodthirsty king bat.

But the bloodthirsty king bat was too far away from the city wall. Before Ruan Bing's soul fire hit the bloodthirsty king bat, he lost power and fell down.

Seeing that Ruan Bing could not hit the bloodthirsty king bat, the Lu Army immediately filled the rifle in his hand with ammunition, then aimed at the bloodthirsty king bat in the air, squeezed the trigger, and fired a series of bullets up, logically speaking, the attack distance of the rifle It is enough to hit the bloodthirsty king bat.

But the elite king bats around the bloodthirsty king bats reacted quickly. Seeing someone about to attack their boss, they immediately stood in front of the bloodthirsty king bats and used their bodies to block bullets for the bloodthirsty king bats.

Because they are Tier B creatures and have the ability to produce sound waves, the ultrasonic attacks of the bloodthirsty king bats will not have much impact on them, allowing them to block bullets safely.

The physical strength of the elite blood bat is still OK, and it directly blocks all the bullets of a magazine, without letting a bullet interfere with the bloodthirsty king bat.

Seeing this, the Lu Army was anxious for a while, and the city wall would be unstoppable if it continued like this!

Fortunately, the Lu Army suddenly thought of something, and immediately ran to a fire guard, picked up the energy magazine on the ground, and replenished the fire guard who had been misfired.

He wants the fire guard to shoot down the bloodthirsty king bats in the air. The elite blood bats can block the bullets of the rifle, and can't even block the fire guard bullets, right?

Even if the Fire Guard can't shoot down the Bloodthirsty King Bat, it's okay to force it back and block its attack...

After more than ten seconds, the Lu Army replenished the ammunition for the fire guard in front of him at the fastest speed, and the fire guard spit out blue fireworks again, and the target was the bloodthirsty king bat 100 meters above.

Seeing bullets, the surrounding elite blood bats wanted to continue to block with their bodies, but the high-speed and high-power fire guards were not comparable to ordinary rifles. They directly maimed an elite blood bat, exposing the bloodthirsty behind. King bat.

The bloodthirsty king bat, who had been launching ultrasonic attacks, did not expect that its elite men would not be able to block the bullets. It didn’t respond to it and was too late to dodge. The bullet fired by the fire guard was hit head-on, forcibly interrupting the attack, and was hit Rolling a few times in the air, it looked like it was about to fall.

However, the bloodthirsty king bat was not injured as a result. Its four flapping wings quickly helped it stabilize its shape and regain its balance.

Although the Lu Army interrupted the attack of the bloodthirsty king bat, most of the soldiers on the wall were in a coma at this time, and there were very few people who could continue to raise their guns to fight.

And the bloodthirsty king bat, who was interrupted, looked at Lu Jun and Ruan Bing on the B1 section of the city wall, and felt annoyed. It knew that most of its subordinates were killed by these two men, but they did not expect that these two men would continue to block. Its offensive, which makes it very uncomfortable.

The unhappy bloodthirsty king bat immediately led the remaining elite blood bats towards the B1 section of the city wall. It had to go and kill the Lu Army and Ruan Bing in person.

The fire guard was still shooting into the air, trying to hit the bloodthirsty king bat and the elite blood bat again, but they were both flexibly avoided by the bloodthirsty king bat, and its speed in the air was still extremely fast.

Lu Jun looked at the bloodthirsty king bats getting closer to the city wall, and didn't panic at all. He immediately took out the Death Tu 8000 and waited for the bloodthirsty king bats to enter the attack range.

In fact, the Lu Jun was eager for the bloodthirsty king bat to come to him, because then he would have the ability to attack the bloodthirsty king bat. If the bloodthirsty king bat always flies in the sky to harass, then he really can't help it...

Another reason is that the infected group is very close to the city wall. If the bloodthirsty king bats are not dealt with and the soldiers can regain their combat effectiveness, the city wall will be broken in less than ten minutes.

Two seconds later, the bloodthirsty king bat flew over a distance of nearly 70 meters and came to the wall of section B1. The bloodthirsty king bat, which is more than three meters long, still looks very imposing and oppressive.

"Fight!" Seeing the bloodthirsty king bat approaching, the Lu Army raised the Shitu 8000 and shouted, and then with a "bang", it squeezed the trigger of the Shitu 8000.

If the Tou 8000 can hit, it will definitely damage the bloodthirsty king bat. After all, the power of the Tou 8000 can definitely damage creatures below Tier A and A.

It is a pity that the bloodthirsty king bat is still too agile. With four wings fluttering, the three-meter-long body directly flashed over a position, avoiding the deadly 8000 bullet, and then dashed backwards, further away from the position of the road army. Near.

Ruan Bing on the side kept throwing soul fire, but was also avoided by the bloodthirsty king bats. After all, the bloodthirsty king bats can even dodge bullets, and the soul fire, which is much slower than the bullet speed, is even harder to hit it. ...
