Amid the sound of alarms one after another, the two men walked towards the control center room.

At the corner, they ran into 2003, who said anxiously, "Chen Xu, Sister Xia, this is bad, this is an alert for an alien invasion."

Chen Xu and the other person 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 appeared, S01 should not have to sound the alarm.

Could it be that there was a large group of strange beasts attacking? Suddenly, Chen Xu remembered the group of strange beasts he encountered on the way to C332 shelter last time. His heart tightened. Could it be such a coincidence?

There were at least a hundred of those strange beasts, and possibly even several hundred. If it was them, we could only pray that the gate of the shelter was strong enough to stop them.

He said, "Let's go ask S01 what's going on 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's an invasion of alien beasts."

S01's voice was a little more serious than usual. "The early warning radar just sounded an alarm. A group of alien beasts are approaching the shelter. There are more than 500 of them. I would like to ask you to help me resist the attack of these alien beasts."

When Chen Xu heard that the number was more than expected, his face looked unhappy and he asked again, "What kind?"

"Acid Ant Beast."

Chen Xu looked at Yang Jinxia. She knew more about the information about the exotic beasts.

Yang Jinxia's expression changed slightly, and he said in a deep voice, "The Acid Ant Beast is a crustacean beast, and its danger level is A-level. Its body fluids are very corrosive, and if there are enough of them, they can melt through the door of the shelter."

"It's troublesome."

Chen Xu took a deep breath. In this world, the alien beasts were classified according to the degree of threat they posed to the shelter.

Some species of alien beasts, like the gorilla, are very powerful individually, but they cannot break the metal door of the shelter. The risk factor is not high, only C level.

So far, less than ten kinds of dangerous beasts with A-level have been found. Unexpectedly, they encountered one of them. Chen Xu sighed inwardly. Sure enough, this dream game would not let him stay in a certain place peacefully until the end of the dream. There would always be various changes, which were equivalent to tests or levels.

Calculating the time, it’s almost time for the first level to appear.

He knew that this kind of thing could not be avoided, and he could only respond proactively. He quickly used his brain and asked, "Tell me honestly, with the current defense system of the shelter, how confident are we that we can stop the attacks of these strange beasts?"

"There is too little data to make an inference." S01's eyes flashed green for a while, and he gave this answer.

Chen Xu's mind moved, and he took the opportunity to make a request, "I remember you said that there are still some people staying in the shelter. Now that we are facing a powerful enemy, we should let them come out and meet each other."

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

"Why?"

"Sorry, this is confidential."

"Then will they join us in fighting the alien beasts?"

"For some reason, no."

Chen Xu sighed and said, "In this 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 strange beasts and your situation will be even more dangerous."

S01 said, "Sir, you misunderstood. They are all the bravest warriors, but for some reason, they cannot go into battle."

"Then tell us the reason." Chen Xu's attitude was very firm.

"Feel sorry."

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

S01 fell silent, and the green light in his eyes flashed rapidly.

Chen Xu glanced at Yang Jinxia and realized that there was hope. The danger to the survival of the shelter must have a higher priority than that secret.

"I see."

Finally, the green light in S01's eyes was replaced by a deep blue light, "Please follow me in."

After saying that, it finally opened the door of 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 G5232. The control console in the middle is several times larger, and there are nearly ten chairs placed in a circle.

The entire space was in full view, and there was no sign of anyone living here. In other words, their previous guess was not correct.

At this time, Yang Jinxia also followed in and looked around calmly.

S01 walked straight to a corner where there were a dozen freezer-like devices.

The top layer of the "freezer" was transparent. Chen Xu and his companion followed and saw that there was a person lying in each of these "freezers", both men and women, most of them were middle-aged or young people in their thirties or forties.

"What is this?" Chen Xu already had a vague guess in his mind, but he still asked.

"These are human cryopreservation devices. The people lying inside are all people who have made great contributions to the shelter. They suffered incurable injuries in the battle with the monsters, and can only rely on this equipment to maintain their lives. One day, when medical technology is more advanced, they will be thawed and treated."

S01 explained.

"So that's how it is." After Chen Xu knew the truth, he finally breathed a sigh of relief and understood why it insisted on not telling him. This was equivalent to a life-saving device. If he told them, it would probably trigger bad intentions.

Yang Jinxia suddenly interrupted, "How can we guarantee that someone will wake them up?"

S01 said, "The shelter has a lot of important production equipment. Once the war is over, the coalition forces 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. The good thing was that he no longer had to worry that someone was secretly spying on them, which solved a huge hidden danger.

The bad thing is that this time they can only rely on the two of them and two robots to fight off the invasion of the alien beasts.

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

PS: I have had a cold these past two days and my nose is stuffy, which is really uncomfortable.
