"Teacher Lu also often said this." Lu Yun said, digesting Bing Shijue's previous words as if he didn't understand.

"We were all human beings living together more than 20 years ago, but with this picnic area." Bing Shijue shook his head, his mood became complicated for a while, and he turned to ask Lu Yun, "You are in the picnic area, have you ever been to school?" Or have you ever studied in class? ”

"No, Mr. Lu will give me some books." Lu Yun said, his fingers touched the tabletop, and then the appearance of the books that Bing Shijue had seen in her cabin appeared before, "When I was very young, Teacher Lu taught me to read, write, and read some articles. After that, because the disease in his legs worsened, he was basically outside, or went to treatment. ”

"So I read books by myself for the rest of the year." When Lu Yun spoke, he didn't look like a twenty-year-old girl should have the youth, or the calmness that a twenty-year-old girl should have, but as pure as a little girl missing her parents, "Mr. Lu will take me to his research institute about once a year and let me enter a transparent room with some green gas coming down. ”

At that time, his expression was very strange, as if he was very uncomfortable. But his expression was even stranger when he saw that I was able to do nothing in this gas. Lu Yun tilted his head sideways, trying to recall, "Teacher Lu will be very good to me in the future, but he will be a lot more unfamiliar later." ”

"Later, when he occasionally saw me, he would say that I was in good physical condition, but it wasn't enough. If I could have a child with someone, that child would have been more physical. Lu Yun's hand drew random circles on the table, "And later I know that I hope that after the child enters this barrier, he will be able to find medicine to treat his legs." ”

"Mr. Lu became like this because he saved me, and I heard from some other people." Lu Yun said, his fingers lightly pressed the tabletop, and then the tabletop flooded like a wave, showing the young Lu Licheng holding a girl in his arms, and his legs were a little staggering, "So I should also help Teacher Lu." ”

"I see." Bing Shijue listened, nodding his head from time to time, no wonder he always felt that the age gap between Lu Licheng and Lu Yun was not quite right. It is said that it is a grandfather and granddaughter, which seems a little too small, but if it is a father and daughter, it is too big. And the title of the two is also suitable. Now I can basically figure out the general situation according to Lu Yun's account.

"Poor Lu Yun." Bing Shijue couldn't resist the idea of trying to appease the child, from what she had just said, it was obvious that she didn't even have a concept of her age, and only had the most basic predators in the picnic area in her mind, as well as some superficial understandings that she had read from books when she was a child, and then because Lu Licheng might want to recover her legs, she didn't suppress her emotions and said the wrong words to her.

"Why am I pitiful?" Lu Yun blinked her eyes instead, looking at Bing Shijue.

"No, nothing." Bing Shijue shook his head, "In this way, you said that you haven't read a book, right, then I just know a little bit about it, can I teach you briefly?" ”

"Okay, I like the time when Mr. Lu taught me to read." Lu Yun's eyes flashed with a look that didn't match her age, "Then what do I call you, Teacher Bai?" ”

"No need, just call it Bai Bing." Bing Shijue said, "Then how do I find the book I want?" ”

"It's very simple, we all have F-level permissions now, so Bai Bing, you just need to hold these down, and then you want the 'book'." Lu Yun said, his fingers gripping the corner of the table and closing his eyes. After a while, the liquid in the corner of the table began to condense, and finally combined into a flat plate.

"There are some books in it, all of which I have read." Lu Yun handed the tablet to Bing Shijue, and after Bing Shijue swept it simply, he couldn't help but sigh.

There are textbooks from the third or fourth grade of elementary school, and then there are some picture books and fairy tales that children read. But they are all cruel, and they have been modified by the picnic area, telling the children to be brave and not hesitate, all for their own survival, or for the survival of the team.

"Mental age is about ...... I think I'm about 11 or 12 years old. Bing Shijue picked up the tablet, pressed it on the corner of the table again, and the moment he closed his eyes, a pure black and white interface appeared in front of him, and when he let go of his hand, the picture disappeared.

"Pretty good technology." Bing Shijue carefully shielded the cities and spaceships in the sea of his knowledge, touched the tablet again, looked at the ancient search interface, and downloaded all the books he had read, as well as the books he had used for the children when he was a teacher. And also found a lot of instructions about the picnic area.

After downloading a few thousand copies, Bing Shijue was reminded that the amount of information available to him with F-level clearance had reached the monthly limit.

"Preventing greed from chewing too much can also make people have the idea of continuing to be promoted, and by the way, you can also know who downloaded so many books as part of the future absorption." Bing Shijue knew that the current managers of the picnic area were actually the managers of the former city, so he could basically guess a small part of this set of logic.

At nightfall, after Bing Shijue briefly reviewed the low-end knowledge of the lower primary school to Lu Yun, he began to explain in detail. She also listened carefully, her biological age was twenty years old, and her ability belonged to the controller of brain development, so the speed of receiving knowledge was far beyond Bing Shijue's imagination, and she was more like a robot than an ordinary person.

In just a few hours, she read all the books on all the subjects in primary school, recorded all the knowledge in her mind, and some things she didn't know much about could be immediately understood after asking Bing Shijue. Science and math are the more troublesome things, but thanks to the high level of technology in the picnic area, she can show formulas, models, or physical examples directly on the table to help her understand.

After more than a dozen exercises in oral expression and writing, the way she spoke and asked questions was no longer like a child, and before falling asleep, Lu Yun also had a basic understanding of the physiological structure of men and women, and knew that her previous actions were indeed not suitable in the city.

But this is in the picnic area.

"Thank you." Lu Yun put away the tablet book in front of her, and nodded slightly at Bing Shijue, in the past few hours, her mental age has gradually transitioned from elementary school to junior high school and high school level.

"It's you who learns fast." Bing Shijue only felt unprecedented pleasure and convenience when teaching, because she could say what she would teach, and she reminded herself a little when she was confused, and when she said the first half of the sentence, she could directly say the second half of the sentence, and draw inferences from one another.

"Thank you, Mr. Bai...... I apologize for saying I wanted to have a baby with you. Lu Yun bowed his head slightly very politely at this time, "The way of thinking in your city is really different from that of our Holy Landing District. ”

"Inevitably, you grew up here." Bing Shijue said, his fingers rubbing the surface of the flat book that was comfortable for him.

"That's right, Mr. Bai." Lu Yun stood up and was about to leave this living room when he suddenly turned his head, "In our Holy Landing District, some important things will be displayed on the wall every morning, and they will slowly appear with your attention, don't be surprised if you see it. ”

"Thank you." Bing Shijue waved his hand at Lu Yun, and only after watching her close the door with his backhand did he let out a long sigh of relief. When faced with such an enterprising student, he will actually find that he has a lot of knowledge shortcomings. Thanks to himself, he is an all-round "immortal cultivator". After scanning all the books, you can also memorize them into your mind, not to mention that you still have a vast space to know the sea of knowledge, and you can integrate all the knowledge and books.

"Take advantage of the long night and take a look at the city along the river." Bing Shijue kept in mind the appearance of the city along the river he had seen before, and why he was recognized as a defector, so he quickly washed his body in his familiar bathroom, came to the soft bed that made him a little psychologically uncomfortable and physiologically comfortable, and closed his eyes.

And his sight quickly crossed more than a thousand kilometers of ocean and came to his original city.

City along the river.
