"Thank you?" The strings were very concerned about Harold's reaction and did not pass it aside.

"Why do you want to thank you? Wait a minute... I remember you saying you used to be a Vault dweller too? Harold smiled and scratched at the deformed green skin on his arm.

"yes, I used to wear one of those Vault-Tech beep boys that Vault-Tech gave us, but then in... I lost something afterwards. He pointed at Andy.

"I was very young and didn't know what the adults were doing with this thing that I had attached to my arm, but then Diana taught us how to use it.... You may think of some things, but those old things don't seem to be very suitable for taking your time now. If you're willing, let's talk about what you should do next. Andy nodded, time is limited, and it is time to race against time.

Harold pointed his arm to the east.

"The water supply to the garden comes from the power generation wastewater discharged from the factory area, which flows from an artificial lake upstream to an underground pipeline, where it is naturally filtered and continues to flow downstream into the flood discharge facility in an artificial river. So, you just have to go to the artificial lake to the east and you can find the source of this water, which is the geothermal power plant. Cylinder Brain interrupted him impatiently.

"Hey! Don't nag you guy, we've heard this information in the mouth of the robot in the flood discharge facility for a long time, and you won't say anything about how to get to the center of the nursery to find the root cause of the problem, is it? Harold was stunned for a moment, and spread his hands helplessly.

"Oh, your metal jar may be more slippery than slippery... I'm sorry I didn't mean to disparage you, I meant to say... I don't know exactly what information the robot gave you, but it never went against its procedures to wander around the area, you know what I'm trying to say? I can tell you exactly what the root of the problem is, but the reason why it is down is very simple... As I said, Diana's state is so abnormal that it doesn't have a chance to recover, and it's still as chaotic here as it was half a year ago. ”

"So the crux of the matter is, why is Diana in an abnormal state?" Xian looked left and right and said her guess.

"The earthquake destroyed her? Or at least to paralyze her? Harold shook his head.

"I said that Diana's very existence was pre-war ... Perhaps the only crystallization of technology that transcends its time, her safety was the most important thing when the nursery was built. Almost all of the situations were taken into account, from the invasion of the bA, the fire, the aging of the equipment, to the various possible threats, and even the direct hit of one or more nuclear bombs, I can say that those things were nothing to Diana. Hearing this, the tank brain laughed out loud.

"But it turned out that none of that happened, and an ordinary natural disaster killed her, didn't it? Tell me what's going on? Harold didn't care about the nittings, just continued his narrative.

"Nothing could threaten her, not even the earthquake that nearly disabled most of the nursery, but... While she is safe, the rest of the nursery is not. String thought for a moment, and suddenly thought of the geothermal power plant that Harold had mentioned again.

"Geothermal power plants are inevitably built in areas that are more vulnerable to earthquakes, and since you say that the earthquake disabled more than half of the nursery's facilities, then the power plant must be the first to bear the brunt. If something goes wrong with the power plant, the nursery will lose energy, and even if Diana is not damaged, she will lose her mobility because of the lack of energy....." Harold shook his head again.

"As far as I know... Although I probably don't know as much about science as you do, sometimes people have some intelligence advantages when they get older, and Diana can't be without an independent energy system or at least an emergency energy facility, and the fact that a geothermal power plant no longer produces energy is not enough to put her in a dead state. Andy's head hurt when he listened, and he tried to find clues from these exchanges, and finally let him find a contradiction.

"Harold, you said that you couldn't threaten Diana before, and now you said that Diana couldn't fall into an abnormality, since the earthquake couldn't help her, why did she need help now?" Harold was silent at this point, and it took him a moment before he explained bitterly.

"yes.... I don't know why, I've been waiting for Diana to go back online and fix everything, but she hasn't moved. But... I had a guess, and it was just a guess, but I thought about it for a long, long time, and I thought that was the only possibility that things had gotten to this point. He stopped talking, and the three of them stood helplessly waiting for Harold to sort out his words.

"Hmm.... I'm sorry, but my guess is that the earthquake didn't hurt Diana, and Diana's current state was a choice she made. The three men looked at each other, unable to comprehend the inference.

"Why?"

"The nursery is in ruins, but she chooses to dream big?"

"I think that guy must be crazy." Harold's expression told the crowd that he had guessed what would be the reaction, and he continued to make his own guessed additions.

"Of course you don't know that the nursery was designed to be a backup of the apocalypse. Do you know what that word means? If the world is destroyed, humanity will need a place to store the seeds of this world, not only the seeds of plants, but also the seeds of animals. The nursery has a huge bank of animal and plant samples, which stores tissue samples or dNA information for almost all organisms known to humans in the Old World.... That's truly priceless. "I understood what Harold was trying to say.

"You mean, the earthquake cut off the power to the geothermal power plant, which didn't matter to Diana, but it wasn't the same for the sample bank, where there was no energy and all the storage in it would rot shortly after the maintenance facility went down.... Diana certainly wasn't going to sit idly by, even if... Even if it's at the expense of herself, right? Harold nodded solemnly.

"I can't afford to get out of here, so I can't prove my guesses right, but I have a clue that can support my own thoughts: before I came here, I saw Diana's new little assistant, Akisha, passing near the garden area, and although I didn't have time to talk to her, I knew in her direction that she was going to a geothermal power plant."

"I'm guessing you're going to ask her what she's doing there, right? Quite simply, the geothermal power plant had the nursery's only manual energy control valve, and Diana was not able to redirect her energy supply to protect the sample bank due to program constraints, but it would be feasible if one person was authorized to go there and do it manually. The three of them listened to Harold's words, although he said that it was all his speculation, but several of them really couldn't think of any loopholes, just like Harold said before, even if there was nothing to threaten Diana, she could choose to sacrifice herself to protect what she cared about.

While this did save the precious pre-war biobank, it also left the nursery in devastation to this day.

After talking for a while, they decided that the next plan of action was to go to the geothermal power plant and see if they could repair it and restore the nursery's power supply to normal, if Diana was really as good as Harold said, I am afraid that she is the only one in the world who has a different opinion about the new plague.

That night, Andy decided to spend the night at Harold's place, because according to Harold's account, this area was the safest place in the entire garden area in his years of living here.

But then they found out that Harold's little hut was so dilapidated that the old and weak fellow could not improve his living conditions, so he lived here for a long time.

"Let's build a small house." Andy suggests this, and the strings show their support, and although Harold chatters a little about it, he still ends up cutting down the tree with his lawnmower.

After all, he didn't want to spend a night in the open air in the treacherous woods, and even if Harold said it was safe, who knew if there would be a walking tree coming and kidnapping someone at night?
