"But when I was talking to Captain Yan, that giant bat monster had already begun to attack the Great Wall of the Border!" Deng Tundi explained.

"The duration of sunspot activity is generally within a few minutes to tens of minutes, and from the time when the giant bats flew out of the cave in large numbers to the present, it should be certain that it is the result of the violent movement of sunspots."

"But why did they attack the Great Wall of the Frontier so precisely?" Ren Mingxiao asked puzzled.

"If there is a problem with the unit cells in the brains of these giant bats, then according to their past memories, they will reach the Great Wall of the Border in a familiar direction! Besides, their attack method has become extremely special, not flying directly to the Great Wall of the Border, but hiding on the wall of the Great Wall of the Border! It can also indicate that these mutated creatures must have been affected. ”

"They think this is a nest?"

"Possibly! But they could also be waiting for the sunspot event to end! Chen Xunyi said.

"How do you solve this now?" Deng Tundi asked, "The mutant creatures around the entire border Great Wall are constantly stirring, and other places have already dealt with a lot of this situation, if it continues like this, this place is guarded, and other places are likely to be turned over by mutant creatures." ”

"So, I need data from the observatory!"

"If the data says it's going to take a long time for sunspots, what are we going to do?"

"Hold on to the Great Wall of the Border! What else can I do? Yan Shenshi shouted.

"You!" Deng Tun clenched the machine gun in his hand.

"This giant batalist can emit ultrasonic waves like bats, and if you can adjust the sonic device of the Great Wall of the Border to repel birds, you may be able to temporarily let the giant bat monster leave the Great Wall of the Border!"

"I disagree!" Deng Tundi said,

Olev on the side also walked over, "This method is too risky!" If the sonic device is adjusted, many mutated birds will enter the airspace of the survival area. ”

"But there is no way now! With so many giant bats crouching here, if the sunspots don't end, and once they are allowed to enter the survival zone, it will definitely be more troublesome at that time! Chen Xunyi explained.

"I still don't agree!" "Is there any other way?" ”

"Something else? Do you think it's going to be easy to get rid of those giant batalikes? I can't think of any other way, it's up to you how you want to do it! ”

"It's too risky!" Olef frowned and pondered for a moment.

"Isn't it dangerous for these giant bats to lie on the walls of the Great Wall on the border? The imperative is ... ”

"I'm coming!" Yan Shenshi raised his hand and motioned for Chen Xunyi not to speak, he stood there, his eyes staring directly at Deng Tundi and Olev, "The doctor is right, the current situation is not for you to think too much, first get rid of the giant bat monster, and then disperse the personnel to support the rest of the border Great Wall!" ”

"What about mutant birds?"

"Leave that alone, concentrate your forces on the mutated creatures that are destroying the walls."

"Mutated birds will enter the living area in large numbers, and if they enter it, we will be very responsible if it becomes an impact!"

"It's easier than repairing the Great Wall!" Yan Shenshi shouted loudly, "It's just right, it's time to let the people in the Blue Star Government take a look, what is the point of the Great Wall of the Border now!" ”

Olef responded, "I don't know why, I guarantee that as soon as the news comes out, the guards will get into a bunch of trouble, after all, the Great Wall of the Border is ours to defend." ”

"Then I want to ask if the Blue Star government has paid attention to it? They don't think that the amount of blue ore coins given every year will be able to defend the increasingly dangerous Great Wall, right? Moreover, most of the people who come here now are prisoners who need to serve their sentences in prison! What's more, some teams can't squeeze in! Some teams don't even have enough people! ”

Olef obviously sensed that Yan Shenshi was hinting at him, he glanced at Yan Shenshi, and tried to argue, "We defense forces can't help it!" ”

"That's it!" Chen Xunyi shouted loudly, "If you continue to discuss like this, the Great Wall of the border will fall, so hurry up and decide!" ”

"Since Lao Yan has said so, I agree!"

O'Leef glanced at Deng Tun Di and was silent.

"But! How long will it take, and if it's too long, it won't work! Deng Tun said.

"Just wait for the people sent to bring the documents on sunspot activity. I can roughly determine how much time it will take! ”

"Then everyone, listen up!" Deng Tun shouted, he raised the machine gun in his hand and walked towards the soldiers who were guarding there, "Group up according to what I said, and support the other defense areas of the Great Wall on the border." ”

"I didn't see anyone from the Pioneer Team!" Chen Xunyi looked around.

"I've already arranged for them to help the other teams! It's made up of patrols and defenses! Yan Shenshi responded, he glanced at the soldier, and whispered in a helpless tone, "The soldiers of the defense team are too lazy on weekdays and have not been well trained at all, this is the worst thing!" ”

He continued, "Most of the people who died here before were people who had just joined the defense team, who had no experience, too little training, and poor shooting accuracy, which was simply a waste of bullets!" Now the Great Wall of the Border is supported by two other teams! ”

With the sound of metal clashing, the elevator rose to the Great Wall of the Border, the elevator door opened, and the soldiers sent by Yan Shenshi to contact the observatory ran towards them quickly, holding a stack of papers in his hand.

Here it comes! Chen Xunyi turned and walked towards the soldier, and he reached out to take the paper that was handed over.

"The observatory told the details that at the time of this morning, frequent sunspot activity was indeed found, and at the same time, according to measurement calculations, this sunspot activity is the most frequent and intense in the last fifty years!" The soldier looked up at the sky, "Several base stations in Arlandos are disabled. ”

"Strange!" Chen Xunyi squeezed the paper in his hand, "Since the intensity is so great, why does this area of the Great Wall on the border have no impact?" It's just that your wireless communications are a little interfering! ”

"Don't worry about that just yet! How long will the sunspot activity last? Yan Shenshi reminded him.

"Oh!" Chen Xunyi picked up the paper and quickly flipped through the records on the paper, "About half an hour." ”

"That's it! Now that we know the time, what do we do now? Deng Tun asked.

"Adjust the sonic device to a frequency close to the sound emitted by the bat-monster," ,,,
