The exoskeleton robotic arm on Chen Xu's body has not been taken off, and now he wears it when he eats in addition to sleeping. After a long time, he got used to it and didn't find it inconvenient.

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

Around the corner, they bumped into 2003, and it said anxiously, "Chen Xu, Sister Xia, it's not good, this is an alarm for the invasion of alien beasts." ”

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

If only one or two strange beasts appeared, S01 should not have to raise the alarm.

Could it be that there is a large number of strange beasts attacking?

Suddenly, Chen Xu remembered the group of strange beasts he encountered on the way to the C332 shelter last time. It's not that coincidental, right?

There were at least a hundred or more of those beasts, and maybe even as many as hundreds. If they were, we could only pray that the doors of the Vault were strong enough to hold them back.

He said, "Let's ask S01 what the hell is going on. ”

They turned a corner and saw S01 standing in the doorway of the control center.

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

"It's a beast invasion."

S01's voice was a little heavier than usual, "Just now, the warning radar has issued an alarm, and there is a group of strange beasts, which are approaching in the direction of the shelter, and the number is more than five hundred. I would like to ask you to help me defend myself against these beasts. ”

Chen Xu heard that there were more than expected, his face was a little not good-looking, and he asked, "What variety?" ”

"Sour antmon."

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

Yang Jinxia's face changed slightly, and he said in a deep voice, "The acid ant beast is a crustacean beast, and the danger factor is A-level. Its body/fluid is very corrosive, and if there are enough of them, it can melt through the doors of the Vault. ”

"I'm in trouble."

Chen Xu gasped, this world, the classification of alien beasts is based on its threat to the shelter.

Some species of exotic beasts, such as the green-skinned orangutan, are powerful individuals, but are unable to break down the metal doors of the vault. The risk factor is not high, only C.

So far, there are less than ten species of alien beasts with a danger factor of A. I didn't expect to be bumped into one of them.

Chen Xu sighed secretly in his heart, sure enough, this dream game will not let him stay in a certain place until the end of the dream. You have to come up with all kinds of accidents, which are equivalent to tests or levels.

Counting the time, it's almost time for the first level.

He knows that this kind of thing can't be avoided, and he can only deal with it positively. Quickly using his brain, he asked, "Tell me honestly, with the current defense system of the Vault, how sure are you of blocking the attacks of these strange beasts?" ”

"There's too little data to extrapolate." The green light in S01's eyes flickered for a moment, and he gave such an answer.

Chen Xu's heart moved, and he 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 present, it is time for them to come out and meet them. ”

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

"Why?"

"Sorry, it's classified."

"Will they join us in fighting the beasts?"

"For some reason, it can't."

Chen Xu sighed and said, "Since that's the case, then we can only apologize." We chose 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. ”

Chen Xu shook his head and said, "In the end, we are just guests. This place is under attack, where is the reason why the guests should fight desperately while the host hides at home? I can't accept that. ”

S01 said, "Sir, you misunderstood. They were all the most valiant warriors, but for some reason, could not go into battle. ”

"Then tell us why." Chen Xu has a tough attitude.

"I'm sorry."

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

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

Chen Xu glanced at Yang Jinxia and realized that there was a play. The danger of the Vault's life and death must have taken precedence over that secret.

"I see."

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

With that, it finally opened the door to the control center and walked inside.

Chen Xu gave Yang Jinxia a look and took the lead in following.

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

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

At this time, Yang Jinxia from behind also followed, looking around quietly.

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

The upper layer of the "freezer" is transparent, Chen Xu and the others followed, and they saw that in each of these "freezers", there were people lying in them, both men and women, most of whom were young and middle-aged people in their thirties and forties.

"What is this?" Chen Xu already had a faint guess in his heart, and still asked.

"These are human cryopreservation devices, and the people who lie in them are people who have made great contributions to the shelter. In the battle with the alien beast, he was seriously injured beyond healing, and he had to rely on this equipment to stay alive. Wait for a certain day, when medical technology is more developed, and then thaw them and treat them. ”

S01 explained.

"I see." After Chen Xu learned the truth, he finally breathed a sigh of relief, and understood why he insisted on not telling himself. This is equivalent to a life-saving device, telling them that it is likely to trigger bad thoughts.

Yang Jinxia suddenly interjected, "How can you guarantee that someone will wake them up?" ”

S01 said, "The Vault has a lot of important production equipment that the Combine will need in order to quickly resume production once the war is over." ”

Yang Jinxia nodded and didn't ask anymore.

Chen Xu is still thinking about this matter, the good thing is that there is no need to raise his heart to secretly someone is peeping at them, which solves a huge hidden danger.

The bad side is that this invasion of alien beasts can only rely on the two of them and two robots.

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

PS: I have a cold in the past two days, nasal congestion, and it is really uncomfortable.
