Chen Xunyi bent over and strode up, quickly reached out, grabbed the head of the giant bat monster, and pressed it to the ground.

Then he stabbed the end of his throat with a dagger, digging out the flat bones between the shoulder bones on both sides!

He held the bone in his hand and slammed it on the ground, dark brown marrow dripping from the bone.

"This... Is this a weakness of the Giant Bat Monster? ”

"It should be, at the end of the throat, there is a special bone, this bone can produce hematopoietic stem cells, this kind of cell directly penetrates the body fluids in the body, and enters various organs, so that the internal organs of the giant bat monster can function normally, and it is okay if there are no blood vessels inside their bodies."

"Excellent! This Achilles' heel can help us if we meet the bats at short distances. ”

The gunshots are still ringing in the sky, and I don't know how long it has been! The dark clouds in the sky slowly began to drift into the distance under the blowing of the wind, and the clouds became a little thinner, and the sunlight scattered on the ground through the thin clouds.

Immediately afterward, several giant bats crawled towards them.

Yan Shenshi held the machine gun and dealt with the giant bat monster in front of him quite easily according to the position he pointed, while Chen Xunyi held the dagger, coupled with the figure of the giant bat monster, this was still a little difficult for him.

The gunfire began to weaken, and it was clearly felt that the giant batalist was back on the walls of the Great Wall of the Border.

Yan Shenshi left the outer railing and stood in front of him, half-kneeling, aiming his machine gun at the outer railing, almost half a meter above his head.

"Quick! Hurry up and get it done! ”

Chen Xunyi took a deep breath, he turned around, slowly poked his head out of the outer railing, he saw an amazing scene, a dense giant bat monster was lying on the wall, a pair of black eyes looking straight up.

He retracted his head suddenly, and the moment he was stared at by so many eyes, the fear in his heart suddenly welled up in his heart.

Chen Xunyi raised his hand and motioned to turn up the frequency of the sonic device, and when his hand was not lowered, the frequency emitted by the sonic device was steadily rising.

Once again, he stuck his head out of the gap between the outer railings.

A black shadow quickly climbed up, and Chen Xunyi retracted his head sharply, for fear of being bitten down by the giant bat monster, whose head had just exposed above the outer railing.

Yan Shenshi did not hesitate to shoot.

Chen Xunyi stretched his head out again, his gaze looked back and forth on the wall, the frequency still did not reach, he raised his hand and motioned for the sonic device to continue to increase the frequency.

Several times he stuck his head out, and the giant bataquin flew by quickly.

Chen Xunyi gradually noticed that the bodies of the giant bat monsters on the wall began to tremble, their teeth began to chatter, and the sound of heavy breathing became louder and louder.

Then many of the giant batacores spread their bodies, and the biofilm between their arms and feet swayed in the wind.

"Haven't you adjusted the right frequency yet?"

"It's coming!" Chen Xunyi responded.

The Giant Bat Monster's behavior became more and more agitated, and several of them had already left the wall and flew towards the woods in the direction of the Great Wall of the Border.

A few minutes to go! Wait? No, the order should be given to let the people of the team leave immediately.

Among so many giant bats, one of them suddenly opened his mouth wide and roared loudly towards the sky, and his low voice was particularly harsh.

Chen Xunyi immediately retracted his body and made a gesture of completion, he looked at Yan Shenshi, "Hurry up!" ”

"Hmm!"

Just as they were about to run back to their place, several giant bats jumped over from the outer fence at the same time and surrounded them.

Not this frequency!

"Don't shoot, it's easy to hurt them!" Deng Tun shouted.

"Keep cranking up!" Chen Xunyi shouted, "Don't entangle with them, run out!" ”

They ran quickly along the outer railing, and the giant bats quickly followed them.

What's going on? Chen Xunyi was quite puzzled, logically speaking, the frequency of the sonic device would make these guys leave the Great Wall of the border!

But now? His heart began to panic a little, maybe it was the frequency of each giant bat monster, and there was a big difference between the upper and lower limits! The sonic device hasn't reached yet, driving away the giant batamonster that emits higher frequencies.

Yan Shenshi held a machine gun and kept shooting at the giant bats that were approaching them.

Seeing this, some of the people in the team immediately ran to the outer railing, and they prepared to kill the giant batabolite chasing Yan Shen Stone.

Once again, the roar came from outside the Great Wall of the Border.

Chen Xunyi quickly turned his head and looked at the top of the outer column, oh no! It's a trap!

He shouted to the soldiers approaching the outer railing, "Go back!" Don't go near the outer railing! ”

Before he could finish speaking, many giant bats had already climbed over the outer fence and pounced on the soldiers.

The screams once again echoed over the Great Wall of the Border, shaking the hearts of everyone present.

"Let's go! Go back! He shouted again.

"What are you going to do?" Ren Mingxiao took a step forward and was pulled back from behind.

"The fire covers the top of the outer fence, and the frequency of the sonic device continues to be turned up!"

"It's already the highest! There's no way to adjust it! Deng Tun held up the machine gun and kept firing upwards.

What the? Exceeding the limits of a sonic device? Chen Xunyi's heart was completely panicked, he couldn't drive away the giant bat monster, and put the mutant birds in.

"Don't be in a daze, run forward!" Yan Shenshi shouted at him and nudged him with his hand.

"Not good! I misjudged! The limits of the sonic device can't repel the giant bats! ”

"What?" Yan Shenshi glared at Chen Xunyi, he glanced around, "Then give me a way!" ”

The thoughts in Chen Xunyi's mind were quite chaotic, and for a while, his brain was like a mess of hemp rope, the limit! What to do? He kept asking himself a question in his mind.

"There are no old sonic devices! Take it too, and the frequencies they release can be stacked. ”

"Yes! I'll get it quickly, you guys hold on! Deng Tun shouted.

Chen Xunyi seemed to have found a glimmer of life, he clenched the dagger in his hand, ready to deal with the giant bat monster that pounced on him.

The farther and farther they ran, the soldiers with guns to cover them, also kept running.

Several giant bats jumped out of the outer bar in front of them, blocking them, and the giant bats behind them were approaching.

The light of the machine guns continued to fire at the sides of their positions, but the giant bats did not flinch, and still ran towards them.

"No matter! Run ahead! Chen Xunyi said.

"Good!" Yan Shenshi responded, and he shouted at the soldiers in front of him, ,,,
