As a low-rent housing community, the efficiency of land use in the South Bank community is almost close to the limit, each residential building is like a huge square cement column, and the spacing between residential buildings is designed without considering sunlight exposure at all.

Luo Feng's home is on the 32nd floor of one of the 36-story residential buildings.

"Ah Feng, are you going to the martial arts hall tonight?" Wei Wen walked towards another residential building.

"I'm going out to tutor tonight, and I may go to the martial arts hall after the tutoring is over, the time is hard to say, so don't wait for me tonight." Luo Feng smiled and waved his hand, and then stepped on the stairs and quickly rushed upstairs, Luo Feng took four steps in one step, like a swift leopard, blinked his eyes twice, and arrived on the second floor.

3rd floor, 4th floor......

"Step! Trample! ”

Luo Feng, who was running, was very relaxed and flexible, and sometimes let go of the residents who climbed the stairs on other steps.

"Ah Feng, is school out?"

"Yes, Uncle Wang." Luo Feng's breath was not chaotic at all, as a senior student of the martial arts hall, climbing the stairs at this speed was not much different from walking.

In the low-rent housing community, according to the opinion of the vast majority of residents, there is no elevator built. Because once the elevator is built, the occupants will have to pay more rent. Secondly, for the vast majority of people today, even climbing dozens of stairs is a very easy thing.

For them, building elevators in residential buildings is a luxury.

After all, electricity is very expensive, because the energy source of the city's 'defense system' is electricity, and the whole country is in dire need of electricity.

※※※※※※

32nd Floor!

On the 32nd floor, there are a total of eight families, and Luo Feng's family is among them.

"Click!" With the key in hand, Luo Feng opened the door.

"Brother, are you back?" There was a voice from inside the room.

"Hmm." Luo Feng closed the door, swept his eyes, and the whole home was unobstructed, his home is a one-bedroom and one-living room structure, with an area of 36 square meters.

He, his brother and parents, a total of four, live in this 36-square-meter place, and have lived here for as long as he can remember.

"Ah Hua, what kind of book are you reading?" Luo Feng walked towards the small balcony.

On that balcony, a thin teenager with a somewhat sickly fair skin was sitting in a wheelchair, holding an English book in his hand, Luo Feng glanced at it and said with a smile: "Oh, it's about the investment master 'Price'?" Among the investment masters, isn't the stock god 'Buffett' the most famous? ”

Luo Feng doesn't know anything about investment, stocks, or anything.

"Warren Buffett's didn't work very well for me. Price's theories and ideas are very close to some of my ideas and have a reference effect. The emaciated young man looked up at Luo Feng and showed a hint of a smile.

"You keep reading." Luo Feng smiled.

Inadvertently, Luo Feng's gaze swept over his younger brother's legs, and he couldn't help but feel a pain in his heart...... When my brother was a child, he was crushed by a car and broke his legs, which were completely crushed from the thighs down, leaving his younger brother disabled. It is very stressful for a disabled person to survive in today's society. The younger brother can only receive cultural education through the Internet, and he can receive remote network education.

The long-term lack of sunlight exposure made my younger brother's face sickly pale.

And...... doesn't have many friends, so my brother is also more introverted.

"My parents don't have a high salary, and they have to support me and my younger brother, who is still disabled...... The burden on the family is too great, so they can only live in this low-rent house. ”

"My younger brother has a disability and has very little social contact. It will be very difficult to find a wife in the future. Who wants to marry a cripple with a broken leg? ”

"I must change the fate of my entire family!"

Luo Feng said silently in his heart.

"Why, I had a crush on Xu Xin, but I didn't chase her and didn't fall in love?"

"The law says you can get married at the age of 18, so many people fall in love in high school and get married after graduating from high school. There are very few people who didn't fall in love in high school. Why didn't I? ”

"Because, I don't have time to waste on falling in love! My family is not rich, and I don't have any great teachers to guide me, so I can only rely on myself. Luo Feng's eyes fell on the old sofa in the living room, which was a sofa that could be put flat as a bed, "For so many years, a family of four is in this small house, one bedroom and one living room." My brother and I are in the only bedroom, but my parents have been sleeping on the sofa in the living room for so many years......"

"I must let my parents, let my younger brother, live in a big house, a big house with an elevator."

"So that parents can really sleep in a big bed."

"Let my brother, you don't have to work so hard next time."

"The house must have large floor-to-ceiling windows so that the sunlight can fully shine in!"

I don't know how many times Luo Feng has thought about these words in his heart, because of this, he has worked hard since he was a child.

So—

He will become one of the three students who have won the title of 'Senior Martial Arts Student' among the 5,000 students of the Third High School. Of the three, he is the only one with ordinary family conditions. The other two are the children of wealthy families.

……

"Wow~~" The water from the tap kept flowing down, and soon the electric kettle was filled.

"Sneer......" plugged in the electric kettle, Luo Feng sat on the sofa with the history book in his hand, and kept reciting some key points in the book.

Suddenly-

"Drop!"

The electric kettle was boiling, Luo Feng put down the book, and poured water into the hot water bottle. I poured a large plastic cup of hot water and put it on the table.

"In the year 2026, the 'Battle of Hongze' took place at Hongze Lake...... Well, it's 2026. Luo Feng remembers historical events one after another, and among the various disciplines of culture and education, Luo Feng's mathematics is the strongest. But he was most interested in history. Because whenever you look at the history of the 21st century......

He sighed.

This is a history of human transformation!

"Ah Hua." Luo Feng walked to his younger brother's side.

"Brother, what's the matter?" The younger brother Luo Hua put down the book in his hand.

"There are a total of 139 points in this book, I have marked them out, you can ask questions." Luo Feng handed over the history book in his hand, and when his younger brother Luo Hua heard it, he couldn't help but smile and took it: "Okay, it's rare to have a chance to test you, brother, listen, I'm going to ask the question." You're embarrassed if you answer incorrectly. ”

"Just ask." Luo Feng smiled and sat on the sofa.

"With the strength of one person, on the bank of the Yangtze River, he killed the 'Tiger Head Monster', rescued hundreds of thousands of people, and successfully transferred hundreds of thousands of people to the Jiangnan base, who died bravely? Where are the people? How old was at death? What is the detailed date of the time occurrence? Luo Hua looked through it carefully and asked a question.

"The heroic sacrifice is 'Dong Nanbiao', who was posthumously awarded the four-star Hero Medal by the state, and he is a native of Taixing, Jiangsu. He was 39 years old when he died, and the detailed date of the time should be 2018 AD ......" Luo Feng couldn't help frowning.

Younger brother Luo Hua couldn't help asking: "The exact date, what is the date of the month and the day of 2018?" ”

"Well, it seems to be ......," Luo Feng said with some uncertainty, "It seems to be June 18th." ”

"Haha, the first question, you answered it wrong." Younger brother Luo Hua shook his head and said, "'Dong Nanbiao', who was posthumously awarded the Four-Star Hero Medal, is indeed a native of Taixing, Jiangsu, and was 39 years old when he died, but the detailed date of the incident is June 16, 2018 AD. ”

"Ahh

Luo Feng couldn't help patting his head, shaking his head and smiling bitterly, "No. 16 and No. 18 often make mistakes, you ask again." ”

"Okay, listen carefully, question two." Younger brother Luo Hua looked very excited, "In 2023 AD, in ......"

……

The two brothers asked and answered, and time flew by.

"I'm halfway through the book. I asked 68 questions, and you answered 63 correctly and 5 incorrectly. Younger brother Luo Hua looked up at the wall clock on the wall, "Mom and Dad are coming back, I'll ask you one last question, and I'll ask the other half of the questions next time." ”

"One last question? Okay, just ask. Luo Feng's attention was highly concentrated.

"This question is the most basic. You will recount the main events of the 'Great Nirvana Period'. Brother Luo Hua said.

Luo Feng's expression was a little serious, the history of this great Nirvana period is the most important history of human transformation: "At the beginning of the 21st century, there have been several consecutive viral influenzas in the world, from the SARS virus influenza in 2003 AD, to the later influenza A (H1N1) in 2009, to 2013, and finally the more terrible R virus influenza, in the process of transmission, the R virus has evolved into more than 20 variants, making the virus epidemic prevention work more difficult, and there have been deaths in all countries around the world. ”

"With the progress of epidemic prevention work, the epidemic has been controlled."

"However, in January 2015, the R virus evolved into its most terrifying variant, known as the RR virus!"

"In the past, many variants of the R virus were transmitted through bodily fluids, and some variants could be transmitted through water, but they only survived in water for a short time. But this RR virus can be transmitted through bodily fluids, through water. The scariest thing is...... It can even be spread through the air! Survive an astonishing three hours in the air! ”
