The last time they came to this ruin, Qian Yunyue followed Xuanwu directly to the library, and did not do research in the city, but now when they look around, they have found a lot.

According to the various facilities in the city, the main source of power should still be electricity, and the degree of development is at least hundreds of years more advanced than the real world of Qianyunyue, probably because the power plant has stopped operating, or the line has been damaged, and the entire city is currently not electrified. However, since such a huge city can be sunk into the ground, there is definitely a considerable amount of power equipment, and if it can generate electricity, it is estimated that a part of the urban system can be put back into operation.

"It's a pity that there is no map, otherwise it would be much more convenient." Qian Yunyue floated in the air and looked around, it was quite difficult to find what he wanted in such a huge city, let alone an underground warehouse.

"Is Xianggong's original world similar to this?" Yu Ling was very curious about everything in front of him, touching here and there, he didn't expect that there had been such a human society in this world, it was really amazing.

"Let's just put it that way." Qian Yunyue suddenly reacted, if the structure of the city is similar, then there will definitely be a city hall or a central main control room or something like that, he just wants to find a target, but he ignores the most basic thing - intelligence collection, like that kind of main facilities in the city is where he should be looking now, and most of those places will have emergency measures, but now he doesn't know where the center of the city is, so he can only find it slowly.

"It's definitely a lot of fun." Yu Ling looked at the wreckage of the vehicles left on the streets along the way, this was a new and unknown world for her, and it was natural for her to be interested.

"We can try it if we have the opportunity in the future." If the city can be restored, this place may be used as their new stronghold in the Ancient Realm, but it is imperative that they find a warehouse and obtain weapons to fight off the vampires, otherwise there is no future.

It took the two of them nearly a day, it was almost dark, and finally found a building that looked like a management center, speaking of which, there are no high-rise buildings in the city, and the tallest buildings are only a few floors, probably because of this, the city area is particularly huge.

"Sure enough, there's backup power." Qian Yunyue looked at the gradually lit up interior in surprise, the main building of a city like this will definitely have reserve power for emergencies, and this kind of thing can't be taken away. So he searched everywhere and finally found the power distribution room and successfully turned on the backup power.

"Wow! What did you do? It was like daylight in the house. Yu Ling looked around in surprise, why did the environment, which was still dim just now, suddenly brighten.

"Hmm...... Well, you can think of it as a high-end oil lamp. Qian Yunyue didn't know how to explain it, the concept of electricity was still too abstract for Yu Ling, so it would be simpler to use an example close to life.

"I see, it is like a miracle that human wisdom can reach this state." Yu Ling exclaimed.

Miracles? Qian Yunyue now has a different idea in her heart, maybe the development of modern science and technology has indeed brought a qualitative leap to life, but there are terrible disasters that will follow. Of course, this is not to say that there is something wrong with development, it may be that humanity has just deviated a little bit on the way forward. I don't know if my world will be like this in the future, and after reaching a certain height, things will be reversed and destroyed.

In the central main control room, there are many huge screens and operation panels, and Qian Yunyue didn't know which one to operate for a while, and when she was at a loss, a voice suddenly sounded.

"Dear users, the city master system has been restarted, please confirm your identity at the main console and insert the master key to activate. If the system is not activated correctly within three minutes, control is temporarily transferred to the central computer, and the user can only query some information as a guest. ”

"Who?!" Yu Ling was taken aback, she didn't feel any breath at all, why did a voice suddenly appear.

"Don't be afraid, it's okay, it's the sound of the computer system." Qian Yunyue held her hand lightly, he had long expected that he might need permission to operate, but it was already quite good to be able to query information as a visitor.

"Hmm...... Xianggong, don't you think I'm stupid? Yu Ling was always shocked, and she felt embarrassed.

"It's normal for you to react like this, if you don't look surprised, it will scare me." Qian Yunyue touched her face, "Leave it to me next, you can just watch from the sidelines." ”

Qian Yunyue came to the main console and checked it carefully, and found that there was a control panel similar to a palm print unlock on it, and a strange keyhole, no matter what, he had to try it first, so he put his right hand on it.

"Identity verification is in progress, please wait." After about a few seconds, the system voice sounded again, "No login information found, please insert the master key to log in with a new identity." ”

However, where did Qianyunyue have the key, it seemed that she could only give up, and at this moment, Yu Ling suddenly said: "Xianggong, the shape of this keyhole is similar to the pendant of that necklace." ”

Qian Yunyue was shocked, it wouldn't be such a coincidence, right? He hurriedly took out the cross necklace and saw that it was really a little similar, so he didn't care about 3721 and plug it in first, but he didn't expect it to be inserted.

"The master key has been detected and a new identity login is about to begin." A blue light suddenly appeared from the main console, and he began to scan Qianyunyue's whole body, and after about half a minute, the blue light disappeared.

"The user has been confirmed to be a human, the match is 99%, login is allowed, please enter the user name."

"Qianyunyue." This luck is so good that Qian Yunyue herself didn't believe it, she didn't expect that necklace to be the key, it seems that this is Uncle Hai's ancestral city, and his ancestors must be very important people, as for why this key is a silver cross, Qian Yunyue probably wants to avoid falling into the hands of vampires, but looking at it like this, as long as it is a human, it can be.

"The new user logged in successfully, the system has been fully activated and the control has been transferred, and the user can perform the following permission operations." The largest display on the front suddenly lit up, and then a whole bunch of lists appeared.

"Please give me a detailed city plan." Qian Yunyue opened his mouth and said, he didn't have time to check them one by one, so he could only try step by step.

"Allow access, please later." After the central computer responded, a huge map was presented on the screen, "The city plan is available, please check it out." ”

Qian Yunyue's scalp was numb, she didn't expect this city to be so big, the data above shows a total area of 4,230 square kilometers, you can imagine how prosperous it used to be.

"Search the arsenal." Qianyunyue went straight to the point, completed the most important things first, and then studied the rest slowly.

"Allow access, please later." Gradually, several green dots appeared on the map, and many places were red dots, "The search has been completed, and a total of 235 results have been queried." ”

"No, that's all." Qian Yunyue frowned and looked at the map, the red dot was probably a forbidden area, but what he was looking for might be inside, so he wrote down all the locations of the red dot, and then prepared to start looking for it from the nearest one.

Yu Ling stood silently and watched Qian Yunyue finish the operation, and after he took back the key and turned off the system, he let out a long sigh of relief: "Xianggong, can I speak now?" ”

"You little fool." Qian Yunyue didn't expect Yu Ling to hold back for so long without saying a word, probably because she was afraid that if she said the wrong thing and caused trouble, "It's okay, let's go find a weapon." ”

It turned out that the red dot on the map did not mean that access was prohibited, but that it was extremely dangerous, and with the key and the identity of the new login, the two of them successfully entered the first weapons depot, and it seemed that people had moved a lot of weapons before evacuating, but there were still some left.

"This thing is amazing." Qian Yunyue picked up a gun from the box, "This should be an electromagnetic ray gun." ”

However, the weapons that were left behind were probably scrapped products, and none of them could be used normally, and they searched the entire arsenal, but they did not find the kind of firearms that used silver bullets, and it seems that they have to continue to look for them.

The situation in the next two places was roughly the same, and it was still not found, and Qian Yunyue suddenly thought that maybe she should go to the outer warehouse, because if you want to fight against foreign enemies, it should be convenient to put weapons in areas that are easier to obtain.

As expected, they found a lot of silver bullets and guns in the outer warehouse, which was enough to deal with the two vampires.

Before leaving, the two of them used the Jade Spirit Sword to lay a new barrier for the entire city, this place will be an important stronghold for them in the future, but it can't be invaded, if they can make good use of the city's resources, the future life will be called a beautiful one.

Xuanwu heard that they had found a way to fight the vampires, and immediately came to greet them in person, during this time, everyone was already overwhelmed by the vampires, and if they couldn't find a way to deal with it, they didn't know how much damage would be done.

Dozens of Celestial Clan craftsmen rushed to work day and night, melting all the silver products brought by Qianyunyue and then re-smelting them into swords and bows and arrows, preparing for an all-out war with the vampires, but Xuanwu told Qianyunyue that the two of them did not need to participate, and there was something else to ask them.

"Find a mole?" Qian Yunyue looked at Xuanwu suspiciously.

"That's right, this is the news that our scouts desperately obtained, but at present, there is only one clue from the old Taoist. And this guy is very cunning, and he has never shown his feet, but this time the situation is reversed, he will definitely make a move, and maybe he will open the enchantment again to let the enemy in, so the old man wants to ask the two of them to help eradicate the traitor. ”
