"You are?" Yu Xijing looked at the man in front of him, this man felt very familiar to him, but Yu Xijing just couldn't remember who he was.

"Ahem, cough, cough," the man couldn't help but be a little embarrassed when he saw that Yu Xijing seemed to have forgotten who he was, and after coughing a few times, he began to introduce himself: "I'm Wan Yang, that is your colleague Wan Yang of Lao Zhou." ”

"You do know him, even I have seen him." Lucifer couldn't take it anymore and asked.

"You want to lie to me again," Yu Xijing secretly began to complain about Lucifer with a pensive look on his expression: "I don't know each other, how can you know each other." ”

After a while, Yu Xijing's eyes widened, and she made a sudden realization, and said politely: "Oh, I remember, you have changed so much in the past few years, I don't even recognize it." ”

"I'm your neighbor, and I said hello to you yesterday when you caught the bus in the morning." Wan Yang was a little confused when he heard Yu Xijing's words, so he opened his mouth to explain.

"Hahaha, I'll just say I've seen it." Lucifer couldn't help but laugh out loud when he saw Yu Xijing's deflated expression.

At this time, both of them felt that the atmosphere in the air was becoming more and more awkward, and Wan Yang took the lead in breaking the embarrassment: "Why is your hand injured?" Even though Wan Yang was embarrassed to hear Yu Xijing's explanation to Zhou Yu, he still asked this question in order to ease the atmosphere.

"I've been attacked by a smart machine." Yu Xijing was still immersed in embarrassment, her mind didn't turn around, and she forgot what she had just said to Zhou Yu for a while, and opened her mouth to tell the truth.

Wan Yang was even more embarrassed when he heard the different explanation just now, I tried to alleviate the embarrassment, you still demolished my platform, did I offend you in my last life?

Yu Xijing also seemed to realize the increasingly dense awkward atmosphere in the air, so he opened his mouth and forcibly explained: "I mean, what do you think about the recent attack on human beings by intelligent machines, didn't intelligent machines establish three major principles when they were created?" (Asimov's three principles for robots in his book, interested friends can search for them)

When Wan Yang heard Yu Xijing's words, he finally found a direction where he could chat normally, so he opened his mouth to explain to Yu Xijing: "In fact, the current Zhiji still abides by the three principles, and their current program also sets them to never go back and betray the three principles. ”

"Then why do the current intelligent machines still attack humans?" Yu Xijing didn't expect that the casual question would make Wan Yang make such an explanation, and couldn't help but be a little curious: "Isn't it contradictory if you say this?" ”

"Do you know what happened in the fifties of the twenty-first century?" Wan Yang did not answer Yu Xijing's question, but asked rhetorically.

"Humans immigrated to Mars?" As a representative of the history class, Yu Xijing said the standard answer to this question in the history book with some doubts.

"Yes, two or three thousand years ago, someone put forward the hypothesis that if you had an airplane, you would replace it with parts every short time, and at the end of the day, after all the parts of the plane were replaced, would it still be your original plane?" Wan Yang said with some seriousness.

Yu Xijing couldn't help but fall into thought, Yu Xijing wanted to answer this question but didn't know how to answer the most correct answer.

Wan Yang saw that Yu Xijing fell into deep thought, so he asked Yu Xijing another question: "So human beings have survived on Mars for more than 2,000 years, and generations of genes have slowly changed because of the environment of Mars, so are humans humans or Martians at this time?" ”

Yu Xijing was stunned when he heard these unbelievable words, he never thought that the reason for the intellectual machine crisis was the reason for human immigration to Mars, he initially guessed that humans controlled machines, but he didn't expect the truth to be like this.

"So the intelligence machine is only to protect the earth, so it fights against alien creatures?" Yu Xijing thought for a while, and said with a somewhat strange expression.

"What are you talking about? Went to eat. Zhou Yu said to Yu Xijing with his briefcase at this time.

Wan Yang looked up at the wall clock on the wall at this time and said, "I'm going to eat too, don't tell anyone else about this matter, only a few people know about it, let's talk about it when we have a chance in the future." ”

Without waiting for Yu Xijing to say anything, Wan Yang stood up and walked out the door, Yu Xijing continued to think about what Wan Yang had just said.

Zhou Yu came over at this time to help Yu Xijing pick up his schoolbag and said, "What did I talk to Xiao Wan about just now, I heard them say that Xiao Wan won't work here soon." ”

"Why? Uncle Wan, is he resigning? When Yu Xijing heard the news, she recalled the series of words Wan Yang had just said to herself, and couldn't help but be puzzled.

"He, one of his relatives introduced him to a job with a better future, as if he had resigned," Zhou Yu couldn't help but sigh: "He has a good relative, let's go and eat." ”

Yu Xijing stood up and walked towards the door with Zhou Yu. "I don't think he's a relative." Lucifer's voice rang out again.

"It's up to you to see if I believe it or not, you're done." Yu Xijing directly scolded Lucifer back with a word.

"Can't you trust me once?" Lucifer said to Yu Xijing with some despair.

"Hehe, I believe you are a big-headed ghost, you are a liar." Yu Xijing rolled her eyes and said that she no longer believed his nonsense.

……

"Do you want to kill your mouth? You tell everybody else about it. A short, masked woman stood by the window and said to the man beside her.

If Yu Xijing was next to these two people at this time, he would definitely recognize this man as Wan Yang who was just about to go to dinner.

"There's no need, I feel that this person is a capable person, maybe there will be a chance to join our organization in the future." Wan Yang shook his head in response to her after putting on the mask.

"Really? Then I hope that he can live to join our organization in this troubled world," the woman turned her head and stroked her hair and said to Wan Yang, "You better think about why the organization called you back so early." ”

Wan Yang also said with some doubts in his voice, "Yes, why? ”

……

"Have you seen the exam room?" The old man said with concern to the child who was gnawing corn beside him.

"I'm done," Yu Xijing threw the gnawed corn cob into the trash can next to him and said to Zhou Yu beside him: "You better go back to work early, don't delay the work time." ”

Yu Xijing was very helpless at this time, and he didn't know what was wrong today, Zhou Yu was very concerned about him. insisted on taking him to the examination room after dinner, could it be that this is the parent college entrance examination syndrome? Large-scale infectious diseases that will be especially good for children during the college entrance examination?

"That's okay, you take this and take the money," Zhou Yu didn't care about Yu Xijing's urging, and took out the last few twenty yuan coins left in his dilapidated wallet and stuffed them into Yu Xijing's pocket: "You must remember to take the bus when you go back today, it's really okay to take a taxi, tomorrow is the college entrance examination, don't take that unsafe road, then I'll go first." ”

Yu Xijing nodded in response to Zhou Yu's words, and Zhou Yu looked at Yu Xijing and turned to leave. Yu Xijing didn't stop too long and walked towards the bus stop.

After returning home, Yu Xijing took out the severed mechanical arm from the dimensional space and carefully observed it, as if he wanted to find some treasure on this mechanical arm.

"Looking for what?" Lucifer was a little puzzled by Yu Xijing's search.

"What else can I find besides that knife? Looking for something to eat? Yu Xijing was a little dissatisfied with Lucifer interrupting his thinking, and said a word back.

"You humans are so hypocritical?" Lucifer was a little angry after being scolded, so he brought up the previous conversation between Zhou Yu and Yu Xijing: "People in our world don't talk like you. ”

"You know the." Yu Xijing dismantled the mechanical arm in front of him intently, and couldn't help but say another sentence back.

"Cut," Lucifer said disdainfully, "there's something I don't understand." ”

"Can you explain it to me?"

"What's there to explain."

"It's equivalent to saying that you just don't know how to pretend to understand."

"You!"
