Five seconds later, the mutant blood bats, which had organized their formation again, had already arrived at the top of the B1 section of the city wall. However, this time, they did not pay attention to the escort and military support teams of the Blackstone consortium, but directly attacked the road army and Ruan Bing in the center.

Because they know that these two talents are the key to the threat to them. As long as these two people are solved, the rest of them can't do much harm to them.

After giving Ruan bing a blessing, the Lu army didn't even have the time to change the bullet for the dead butcher 8000. He immediately drank a bottle of brain reagent, because he played the time back ability too many times, and his brain power was a little behind.

After drinking the brain reagent, the group of mutant blood bats came to him. The firepower of Xiaowan and Ruan Xue simply could not withstand these mutant blood bats. Seeing this, the Lu army immediately thought about it, and in a moment, it was several times back on the mutant blood bats around.

Although the ability of time backtracking requires the target to cast, it has a special ability after casting, that is, it will form an invisible wall around in a short time, and any enemy creatures that hit the wall will also be controlled.

Therefore, it is difficult for the mutant blood bat to break through the defense of the road army and attack Ruan Bing, which is the reason why the road army can block so many mutant blood bats at the same time.

However, although the Lu army resisted the mutant blood bat, he had to continue to output his brain power during this period to prevent the mutant blood bat from making more attacks.

Seeing that Lu Jun was struggling to support her, Xiao Wan threw her gun to the ground because she was too slow to kill the mutant blood bat by the luge MP-9.

Then use the power to transform the body into a dog form, and jump to the controlled mutant blood bat.

After getting close to the mutant blood bat, Xiaowan attacked the mutant blood bat with both claws together. The fragile mutant blood bat couldn't resist Xiaowan's attack and died under Xiaowan's claw one after another.

Ruan Xue saw Xiaowan coming forward, and immediately turned the muzzle of the gun to shoot in other directions to prevent accidental injury to Xiaowan, who was fighting with the mutant blood bat.

In addition, the surrounding Blackstone Group's guards finally loaded the firepower guard's ammunition, and the firepower guards again ejected deadly fireworks to support the road army in difficulty.

The military support team also kept shooting at the mutant blood bats flying in the air. At this distance, they didn't even need to aim. They just pulled the trigger to the densest place.

With the support of the firepower guard and a group of soldiers, the road army resisted the mutant blood bat Swarm for more than 30 seconds by using the ability of time backtracking. Although his brain power was exhausted again, it would be good if he could successfully defend it.

More than 30 seconds later, Ruan Bing, who was blessed by the road army's ability, finally gathered the soul storm. She opened her eyes, and with her long hair and no wind, she opened her mouth and uttered the words "soul storm" in a low voice.

At the moment when Ruan Bing opened his mouth, an invisible force immediately covered dozens of meters around him. Within the scope of the soul storm, the mutant blood bats suddenly twitched and fell down from the air after a few seconds of convulsion.

Although their body surface seems to have no wound, their soul has been torn by the soul storm, or Ruan Bing has been put into the soul lamp, leaving only a body

Seeing Ruan Bing release the soul storm again, the Lu army was relieved. They did not use time back to the dead mutant blood bats around and let them fall to the ground.

This time, Ruan Bing's soul storm still made great achievements. A large number of mutant blood bats fell from the air. The hunting task hints of grade C mutant blood bats were constantly ringing in the minds of the army, and their dragon titles and coins were also increasing

Eight seconds later, there were not many living mutant blood bats in the sky, and the sky suddenly cleared down.

Ruan Bing killed at least 6000 mutant blood bats in the two soul storms. The fire guards of the road army also killed nearly 2000. There were more than 1000 mutant blood bats killed by the city guards.

In this way, nearly 10000 mutant blood bats were slaughtered in less than half an hour. The city guards and Zhang Deshao were surprised to see the B1 section of the city wall. They didn't even understand what happened

However, the threat from the sky does not seem to be over, because after the death of nearly ten thousand mutant blood bats, with the light from the flares, several huge figures suddenly appeared in public view from a hundred meters above the sky.

The first is a three meter long creature with four wings, similar to the mutant blood bat, followed by five one meter long creatures, which are also similar to the mutant blood bat.

Seeing that some big guys appeared, the road army immediately glanced at these big guys. The data of the biggest creature was that, the bloodthirsty King bat, whose strength was evaluated as level a, was extremely fast. Its appearance would inevitably lead a group of mutant blood bats and be good at ultrasonic attack. 】

the biological data of those five one meter long are: Elite blood bat, whose strength is evaluated as level B, is the guardian of bloodthirsty King bat, good at acoustic attack. 】

it seems that this bloodthirsty King bat is the eldest one of the mutant blood bats. No wonder those mutant blood bats are so smart. It turns out that there are high-level Wang bats behind their backs. Now that the younger brother is dead, the eldest one will naturally come out to revenge."Come on! These things are very powerful. Snipers should gather fire and shoot them down After receiving the information of these creatures, Ruan Bing immediately raised his walkie talkie in the public channel without being reminded by the road army.

Ruan Bing was still very clever. He understood that it was very difficult for ordinary rifles to cause damage to the bloodthirsty King bat at this distance. Only the sniper gun with long-distance sniping ability could threaten the bloodthirsty King bat, so he immediately issued the command.

After hearing Ruan Bing's words, the military snipers all over the city wall did not care to continue to attack the infected body that was close to the wall. They immediately turned the muzzle of the gun and took advantage of the light to aim at the bloodthirsty King bat in the air, ready to pull the trigger.

But before the snipers had time to shoot, the bloodthirsty King bat suddenly stopped in the air and opened its mouth. Then thousands of soldiers on the city wall heard a "squeak ~" sound.

The sound was not so loud as it sounded from my mind. At first, I didn't feel anything. But after a few seconds, many people who heard this sound had serious discomfort.

Because I don't know why, the sound seriously affected the perception, so people just want to cover their ears to drive out the sound in their mind.

But covering their ears did not stop the sound. Many soldiers began to tumble on the ground, and some soldiers' ears began to emit bright red blood
