Chen Xu's exoskeleton robot arm was not taken off. Now he was wearing it while eating except for sleeping. After a long time, he got used to it and didn't feel any inconvenience.

Amid the sound of alarms after alarm, the two walked towards the control center room.

At the corner, they ran into 2003. It said anxiously, "Chen Xu, Sister Xia, it's not good, this is an alarm for the invasion of strange beasts."

Chen Xu and the others couldn't help but look at each other, and both saw the solemnity in each other's eyes.

If only one or two strange beasts appear, S01 should not issue an alarm.

Could it be that there are large groups of strange beasts attacking?

Suddenly, Chen Xu remembered the group of strange beasts he encountered on the way to the C332 refuge last time. His heart tightened, wouldn't it be that coincidental?

The group of strange beasts had at least one hundred, or even as many as a few hundred. If they were them, they could only pray that the gate of the shelter was strong enough to block them.

He said, "Go and ask S01 first."

They turned a corner and saw S01 standing at the door of the control center.

Chen Xu glanced at the closed door behind it and asked, "What happened?"

"It was an invasion of a strange beast."

S01's voice was a little heavier than usual. "Just just now, the warning radar issued an alarm. A group of strange beasts were approaching the shelter, with a number of more than 500. I want to ask you to help me resist the attacks of these strange beasts."

Chen Xu heard that the number was even more than expected, and his face looked a little unfavorable, and asked again, "What kind of variety is it?"

"Acid ant beast."

Chen Xu looked at Yang Jinxia, ​​and she knew more about the information about the strange beast.

Yang Jinxia's face changed slightly and she said in a deep voice, "The acid ant beast is a crustacean beast with a risk factor of Class A. Its body/liquid is very corrosive. If it is sufficient, it can melt through the gate of the shelter."

"It's trouble."

Chen Xu took a deep breath. The classification of strange beasts in this world is distinguished according to the degree of threat to the shelter.

Some species of strange beasts, like green-skinned orangutans, are very powerful in individuals, but cannot break the metal gates of the shelter. The risk factor is not high, it is only C-level.

So far, there are less than ten kinds of strange beasts with a level A-level risk factor discovered. Unexpectedly, they encountered one of them...

Chen Xu sighed in his heart, Sure enough, this dream game will not allow him to stay safely in a certain place until the end of the dream. He always has to make all kinds of changes, which is equivalent to a test or level.

Calculate the time, it's almost time for the first level to appear.

He knew that such things could not be avoided, so he could only respond actively. He quickly thought about it and asked, "Tell me honestly, with the current shelter defense system, how sure is there to block the attacks of these strange beasts?"

"There is too little data to be calculated." S01's eyes flashed for a while, giving such an answer.

Chen Xu's heart moved and took the opportunity to make a request, "I remember you said that there are still some people who stay in the shelter. Now that the enemy is in front of them, they should also let them come out and meet them."

S01 said, "Sorry, I can't agree to this request."

"Why?"

"Sorry, this is a secret."

"Then will they go fight with us to fight the strange beast?"

“For some reason, it cannot.”

Chen Xu sighed and said, "Since that's the case, we can only apologize. We choose to leave."

S01 said, "Sir, this is not a wise choice. If you leave at this time, you will be attacked by a strange beast and your situation will be even more dangerous."

Chen Xu shook his head and said, "After all, we are just guests. When we are attacked here, why should we let the guests fight to the death? The owner hides at home? I can't accept this kind of thing."

S01 said, "Sir, you misunderstood. They are all the bravest warriors, but for some reasons, they cannot fight."

"Then tell us the reason." Chen Xu was very tough.

"Feel sorry."

Chen Xu looked regretful, "S01, I am willing to believe you, you will not harm us. However, I don't believe in those people. I hope you can understand."

S01 stopped making a sound, and the green light in his eyes flashed quickly.

Chen Xu glanced at Yang Jinxia and realized that there was a chance. The danger of life and death in a refuge must be higher than that secret.

"I see."

Finally, the green light in S01's eyes was replaced by a dark blue light, "Please come in with me."

After saying that, it finally opened the door to the control center and walked in.

Chen Xu gave Yang Jinxia a look and followed in first.

The scale of this control center is much larger than that of the G5232. The console in the middle is several times larger, and nearly ten chairs are placed, forming a circle.

The entire space is clear at a glance, and there is no sign of someone living here. In other words, their previous guesses are not correct.

At this time, Yang Jinxia, ​​who was behind, also followed in and looked around quietly.

S01 walked straight to a corner where there were more than a dozen freezer-like equipment.

The upper layer of the "freezer" is transparent. Chen Xu and the others followed and saw that there was a person lying in each such "freezer", including men and women, most of whom were middle-aged and young people in their thirties and forties.

"What is this?" Chen Xu had a vague guess in his heart, and he asked.

"These are human freezing equipment. Those lying inside are people who have made great contributions to the shelter. In the battle with strange beasts, they were seriously injured and could only rely on this equipment to maintain their lives. Wait for one day, after medical technology is more developed, they will be thawed and treated."

S01 explained.

"So that's how it is." After Chen Xu learned the truth, he finally breathed a sigh of relief and understood why it insisted on telling itself. This is equivalent to a life-saving device. If he told them, it may trigger bad thoughts.

Yang Jinxia suddenly injected, "How can I guarantee that someone will wake them up?"

S01 said, "The shelter has many important production equipment. Once the war is over, the United Army will definitely need these equipment in order to quickly resume production."

Yang Jinxia nodded and stopped asking.

Chen Xu was still thinking about this matter. On the good side, there was no need to be polite to secretly see someone peeking at them, which solved a huge hidden danger.

On the one hand, the invasion of the strange beasts was only dependent on the two of them and two robots.

He said in a deep voice, "Next, let's discuss how to deal with those acid ant beasts."
