"Whose phone number?" Xia Jiuying walked over and asked.

Dangdang, there was a knock at the door, and Xiao Yuan motioned for Xia Jiuying to open the door.

"Ning Lan, why are you!" When Xia Jiuying went to open the door, Xiao Yuan subconsciously lowered his voice and asked.

"Xiao Yuan, who are you talking about, Ning Lan!" Although Xiao Yuan lowered his voice, Xia Jiuying still heard it clearly, he stopped suddenly, turned his head, his face was shocked, and his voice trembled a little, fortunately, she never watched horror movies because of her illness, otherwise if she had watched "Midnight Bell", it was estimated that she would have fainted at this time.

"Yes, Ning Lan!" Xiao Yuan covered the earpiece, took a deep breath, and tried to calm himself down and said.

"How is that possible?" Xia Jiuying's voice couldn't help but raise a little.

Dangdang, the knock outside the door was louder, but Xia Jiuying suddenly shuddered, ran back again, grabbed Xiao Yuan's arm, stared at the door with a frightened expression, and said, "Xiao Yuan, go and open the door, I'm afraid!" ”

"The one who knocked on the door must be the master, with me, nothing will happen, you wait here, I'll open the door." Xiao Yuan patted Xia Jiuying's arm with one hand, comforted her, said to the phone receiver for a while, then put down the phone receiver, got up and went to open the door.

"Big brother, are you talking to Sister Yingying?" After Xiao Yuan left, Ning Lan's voice came out again in the earpiece, Xia Jiuying sat next to her and vaguely heard Ning Lan mention her name in the earpiece, and was startled again, but also felt very curious, and finally curiosity overcame fear, and picked up the earpiece with trembling hands, and her voice was also a little trembling, "Hey, are you really Ning Lan?" ”

"Sister Yingying, is it you, I'm really Ning Lan, your voice fluctuations show that your emotions are very unstable, are you afraid of something?" Ning Lan said.

"You suddenly ran into the phone, and my sister was scared." Xia Jiuying heard Ning Lan's voice, which was somewhat similar to herself, and her curious inquiry, the original fear disappeared a lot, and when she explained, her voice was not as trembling as it was just now.

"Isn't this weird, the phone is controlled and connected through a computer system, and I go into this system, and the sound waves are sent here through the computer system, just the phone, what's there to be afraid of?" Ning Lan's fear of Xia Jiuying was obviously incomprehensible, and the explanation was reasonable.

"Hehe, listening to your explanation, I understand, and I'm not afraid." Xia Jiuying smiled and said.

"Is it Ning'er's phone, let grandpa say a few words." At this time, Xiao Yuan led the old man into the room, and the old man saw Xia Jiuying on the intercom, walked over, and asked eagerly.

"Yes, it's Ning Lan." Xia Jiuying said, and gave the phone receiver to the old man as she spoke.

"Ning'er, why did you get on the phone, tell grandpa quickly, where is the thief who stole you, grandpa sent someone to arrest him." The old man said into the earpiece, his voice a little excited, but this excitement was obviously not due to fear, but to the agitation of the most important thing when it was lost and recovered.

"Did I get stolen, Ning'er didn't know, Ning'er slept and got up, and found that there was a big world outside Ning'er's home, so she came out of the house, but then she couldn't find her home again, she was a little scared, she checked the knowledge base, and knew that you humans could call and contact, so Ning'er found the telephone program control center and called over." Ning Lan explained.

"Master, you press the hands-free." When the old man was answering the phone, Xiao Yuan listened hard with his ears on the side, so he said to him.

"Ning Lan, how did you find the phone here, I don't seem to have told you the phone number here, and the phone here shouldn't be in my name?" After the old man pressed the speakerphone, Xiao Yuan asked curiously.

"This is very easy to solve, Ning'er doesn't know the phone number of the eldest brother, but there are sonometers of the eldest brother, grandpa and Sister Yingying in the knowledge base, so Ning'er traversed the phone numbers in the Berkeley telephone program-controlled database and found it through sound comparison." Ning Lan said.

"Ahh Xia Jiuying exclaimed when she heard this.

Xiao Yuan was also stunned, and a series of thoughts flashed in his mind, what a spectacular phenomenon it would be for all the people who had phones in Berkeley to receive the same call tonight, and the next day when everyone knew that they all answered the same call, what kind of sensation would it cause, of course, this matter can be regarded as a big accident for the Berkeley Telecommunications Bureau, I don't know if anyone will complain about them tomorrow, how will they deal with this matter, will they call the police, will Ning Lan be named a hacker, Wanted by the police......

"What is traversal?" The old man was not familiar with the term traversing the computer, so he didn't seem too surprised, but asked with a frown.

"Traversing is to call all the calls in the database." Ning'er said.

"Ning'er, you ......" After listening to Ning Lan's explanation, the old man was also stunned, stunned for a moment, and then cried and laughed, "Ning'er, do you know that you are in trouble, do you know how much impact you have done this?" ”

"Is Ning'er in trouble, but Ning'er wants to go home?" Ning Lan heard the old man's words with a bit of reproach, and said with some grievances.

"Ning Lan, your home was stolen, the reason why you can't find it is probably because they shut it down, you can't go back until the two servers are recovered, wait for me to open the notebook, you will return to my notebook immediately, and when you come back, the eldest brother will find you a better party to let you settle down." Xiao Yuan said that for the sake of today, the most important thing is to get Ning Lan back from outside, and not let her wander around the Internet at will.

"Can't you go back to those two servers?" Ning Er couldn't help but be a little disappointed when she heard Xiao Yuan say that she couldn't go back to her home, but she still agreed obediently, "You turn on the phone now, tell Ning Er the IP address after turning it on, Ning Er has never been out before, and she doesn't know the IP address at home." ”

"Big brother will turn on the phone immediately, Ning Lan, before you leave the phone program control center, you must remove all the traces you left inside, including all the call records of your calls, and you can't leave any traces, understand?" Xiao Yuan said again.

"Don't worry, Ning'er used the special channel of the program control center to call, and it will not leave any traces." Ning Lan said.

"Well, I'm relieved, you wait a minute." Xiao Yuan said, he came to the computer desk in the room, connected the ThinkPad laptop to the network, and after turning it on, he told Ning Lan the IP address of the laptop over the phone.

Ning Lan hung up the phone, and a few seconds later, a slim girl appeared on the laptop screen, with a bubble on the side of her head, which read: "Ning Er is back again." ”

"It's good to come back, it's good to come back." The old man laughed, his face was relieved, but his voice trembled slightly, now, Ning Lan has become his new spiritual sustenance, and he is naturally very relieved to be lost, and even wants to shed tears.

"Ning Lan, have you cleared all traces of the outside?" Xiao Yuan still asked uneasily.

"Don't worry, it's cleaned up, I didn't know that the call was made by Ning Lan, but Ning Er's home is gone, it's so sad." Ning Lan said.

"Then I'll rest assured, you can live here for a few days with peace of mind, and I'll find you a better home in two days, you will definitely like it." Xiao Yuan comforted Ning Lan.

Seeing that Ning Lan was back, the old man was also relieved, and naturally it was not good to continue to stay in Xiao Yuan's bedroom, after he left, Xiao Yuan and Xia Jiuying also slept, as for what kind of turmoil the outside world would cause because of Ning Lan's city-wide call, it was not for them to worry about.
