RR

Nanan Residential District, a low-rent housing complex, utilized land almost to its extreme efficiency. Each residential building resembled a massive square concrete pillar, with spacing between them designed without any consideration for sunlight. Luo Feng's home was on the 32nd floor of one of these 36-story residential buildings. "Ah Feng, going to the Martial Arts Hall tonight?" Wei Wen asked, walking towards another building. "I have a tutoring session tonight. I might go to the Martial Arts Hall after it ends, but the time is uncertain. Don't wait for me tonight," Luo Feng said with a smile, waving his hand. Then, he quickly ascended the stairs, taking four steps at a time, like a swift leopard. In the blink of an eye, he was on the second floor. Third floor, fourth floor... "Thump! Thump!" Luo Feng, sprinting upwards, was effortlessly agile, occasionally making way for other residents climbing the stairs. "Ah Feng, school's out?" "Yes, Uncle Wang." Luo Feng's breathing was perfectly steady. For an Advanced Student of the Martial Arts Hall, climbing stairs at this speed was no different from a leisurely stroll. The low-rent housing complex, based on the overwhelming opinion of its residents, did not install elevators. Because once elevators were installed, residents would have to pay more rent. Secondly, for the vast majority of people nowadays, even climbing dozens of flights of stairs was an easy task. For them, installing elevators in residential buildings was a luxury. After all, electricity was expensive, as the energy for the entire city's 'defense system' was electricity, and the entire nation was in urgent need of electrical power. ...32nd floor! On the 32nd floor, there were a total of eight households, and Luo Feng's family was one of them. "Click!" Holding the key, Luo Feng opened the door to his home. "Brother, you're back?" A voice came from inside. "Mm." Luo Feng closed the door, his gaze sweeping across the entire home, which was a one-bedroom, one-living room layout, covering 36 square meters. He, his younger brother, and his parents—a family of four—lived in this 36-square-meter space. They had lived here ever since he could remember. "Ah Hua, what are you reading?" Luo Feng walked towards the small balcony. On the balcony, a thin, pale-skinned young man sat in a wheelchair, holding an English book. Luo Feng glanced at it and chuckled, "Oh, it's about the investment master 'Price'? Among investment masters, isn't 'Buffett' the most famous stock god?" Luo Feng knew nothing about investing or stocks. "Buffett's methods aren't very suitable for me. But Price's theories and ideas are very similar to some of my own thoughts; they offer valuable insights." The thin young man looked up at Luo Feng, a smile on his face. "Keep reading," Luo Feng smiled. Inadvertently, Luo Feng's gaze fell upon his brother's legs, and a pang of pain struck his heart... When his brother was young, his legs were crushed by a car, completely mangled from the thighs down, leaving him disabled. For a disabled person to survive in today's society, the pressure is immense. His brother could only receive cultural education through the internet, via remote online learning. Long-term lack of sunlight exposure gave his brother's face a sickly pallor. And... with few friends, his brother was also quite introverted. "Mom and Dad's salaries aren't high, and they have to support both me and my brother, who is disabled... The family burden is too heavy, so we can only live in this low-rent housing." "My brother is disabled and has little contact with society. Finding a wife in the future will be very difficult. Who would be willing to marry a cripple with crushed legs?" "I must change the fate of this entire family!" Luo Feng thought silently. "Why didn't I pursue Xu Xin, whom I secretly liked? Why didn't I date?" "The law states that you can marry at 18, so many people date in high school and get married right after graduation. Those who don't date in high school are very few. Why didn't I?" "Because I don't have time to waste on dating! My family isn't wealthy, and I don't have any powerful teachers to guide me; I can only rely on myself." Luo Feng's gaze fell on the old sofa in the living room, which could be flattened into a bed. "For so many years, a family of four, in this small 36-square-meter apartment, one bedroom and one living room. My brother and I share the only bedroom, while Mom and Dad have been sleeping on the living room sofa all these years..." "I must make sure my parents and my brother live in a big house, a big house with an elevator." "Let Mom and Dad truly sleep in a proper bed." "Let my brother not have to struggle so much every time he goes downstairs." "The house must have large floor-to-ceiling windows, allowing sunlight to fully stream in!" These words had echoed in Luo Feng's heart countless times. Because of this, he had always worked hard since childhood. Therefore— He became one of only three students among the five thousand at Third High School to earn the title of 'Advanced Student of the Martial Arts Hall.' Among these three, only he came from an ordinary family. The other two were children of wealthy families. ..."Whoosh whoosh~~" Water continuously flowed from the tap, quickly filling the electric kettle. "Hiss hiss..." Luo Feng plugged in the electric kettle, then sat on the sofa with his history book, constantly memorizing key points. Suddenly— "Beep!" The electric kettle boiled. Luo Feng put down his book and poured water into a thermos. He also poured a large plastic cup of hot water onto the table. "In 2026 AD, the 'Hongze Battle' occurred in Hongze Lake... Hmm, it was 2026." Luo Feng recalled historical events one by one. Among all subjects in his cultural education, Luo Feng was strongest in mathematics. However, he was most interested in history. Because whenever he looked at the history of the 21st century... He couldn't help but sigh with emotion. This was a period of human transformation! "Ah Hua." Luo Feng walked over to his brother. "Brother, what is it?" His brother, Luo Hua, put down his book. "This book has a total of 139 key points. I've highlighted them; you can quiz me." Luo Feng handed over the history book. Luo Hua smiled as he took it. "Alright, it's rare to have a chance to test you, Brother. Listen carefully, I'm going to ask questions. It'll be embarrassing if you get them wrong." "Ask away," Luo Feng said with a smile, sitting on the sofa. "Who was it that, single-handedly, on the banks of the Yangtze River, slew the 'Tiger-Headed Monstrous Flood Dragon,' saving hundreds of thousands of people and enabling them to successfully relocate to the Jiangnan Base, ultimately sacrificing himself heroically? Where was he from? How old was he when he died? What was the exact date of the event?" Luo Hua carefully flipped through the book and posed a question. "The one who sacrificed himself heroically, posthumously awarded the Four-Star Hero Medal by the nation, was 'Dong Nanbiao.' He was originally from Taixing, Jiangsu. He was 39 years old when he died. The exact date of the event should be 2018 AD..." Luo Feng frowned slightly. His brother, Luo Hua, pressed on, "The exact date, what month and day in 2018 AD?" "Hmm, it seems to be..." Luo Feng said, a little uncertainly, "It seems to be June 18th." "Haha, you got the first question wrong!" His brother, Luo Hua, shook his head. "Dong Nanbiao, who was posthumously awarded the Four-Star Hero Medal, was indeed originally from Taixing, Jiangsu, and was 39 years old when he died. However, the exact date of the event was June 16th, 2018 AD." "Ah!" Luo Feng slapped his head and chuckled wryly, "I always mix up the 16th and 18th. Ask another one." "Alright, listen carefully, second question." His brother, Luo Hua, seemed excited. "In 2023 AD, in..." ...The two brothers, one asking and one answering, watched time fly by. "I've already asked half of this book. I asked 68 questions, and you got 63 right, missing 5." His brother, Luo Hua, looked up at the wall clock. "Mom and Dad will be back soon. I'll ask you one last question, and we'll do the other half next time." "Last question? Alright, ask away." Luo Feng's attention was highly focused. "This question is the most basic. Recount the main events of the 'Great Nirvana Period,'" his brother, Luo Hua, said. Luo Feng's expression became serious. The history of the Great Nirvana Period was the most important period of human transformation: "In the early 21st century, several viral flu outbreaks occurred globally, from the SARS virus flu in 2003 AD, to the later H1N1 influenza A in 2009, until 2013, when the even more terrifying Type R virus flu finally emerged. The Type R virus, during its spread, evolved into more than twenty variants, making virus prevention efforts even more difficult. Every country worldwide reported deaths." "With the progress of prevention efforts, the epidemic was brought under control." "However, in January 2015 AD, the Type R virus evolved into its most terrifying variant, known as the RR virus!" "Previous Type R virus variants were transmitted through bodily fluids, and some variants could be transmitted through water, but their survival time in water was very short. However—this RR virus could be transmitted through bodily fluids and water currents. The most terrifying thing was... it could even be transmitted through the air! Its survival time in the air reached an astonishing three hours!"
