"You...... You ......" Su Lan trembled angrily, then raised the wicker, and said angrily: "Lu Yuan, let me repeat again, my surname is Su, your surname is Lu, you are not my brother!"

Lu Yuan's face was straight, and he said sternly: "Yes, in terms of blood." We are not brothers and sisters, but don't forget, your mother is married to my father, and we are brothers and sisters in the legal sense, and no one can deny it! Now that my parents are not here, the eldest brother is the father, and I don't care who you spent the night at last night, I am already very accommodating to you!"

The wicker shook and fell with a snap, but it was pumped on the willow tree. Su Lan took a deep breath and said viciously: "I'm eighteen years old, and I'm an adult. I'll spend the night at my fellow students, so I don't have to worry about you. I don't need you to stare at me every day like a fart. ”

Lu Yuan smiled bitterly, shrugged his shoulders and said, "Do you think I am willing?" Dad once instructed me to take care of your cabbage, and don't let the pig of unknown origin arch it." It's a promise between men and men, and I have to fulfill it. ”

"You talk nonsense. When did Dad say that, how I don't know. Su Lan's voice raised an octave, and her cheeks flushed with shame.

Lu Yuan tilted his head and recalled, "I vaguely remember, it was a sunny afternoon, and my father came to pick me up from school, and I picked you up by the way." ”

Su Lan covered his forehead in pain: "You still have to be shameless." ”

"Hey, do you remember?" Lu Yuan said happily, "Even when I was on the road, my father saw a Chinese cabbage seller on the side of the road, so he said to me seriously: 'Son, our family also has a Chinese cabbage that has not grown, you must watch it, don't let some unknown pig arch it'." ”

"When did it happen? junior high school, high school?"

"Kindergarten Kindergarten. ”

Su Lan almost vomited blood, his face was blue, his eyes were fierce as if he was going to kill, he gritted his teeth, dropped the wicker, didn't say a word, dragged the suitcase and turned his head away.

Lu Yuan smiled slightly, pulled up the lever, and began to tail in a high-spirited manner.

Lu Yuan and Su Lan are indeed not brothers and sisters, her father died when she was six years old, and later married the divorced Lu Yuan's father. They grew up together in open crotch pants, and they didn't agree from the beginning, Su Lan never called him brother, and the two of them would quarrel within three minutes of getting together, and then start a fight.

I vaguely remember that one day, Lu Yuan snatched Su Lan's lollipop, Su Lan turned around and opened a stone to Lu Yuan, and after the scar, the scalp never grew hair again.

Since then, Su Lan has left an indelible mark on Lu Yuan's life and on the back of his head.

Pulling a distance of four or five meters, he followed behind Su Lan without hesitation, and looked into the distance, the city wall stretching for dozens of kilometers in the distance was majestic and magnificent, as high as a building.

That was the destination of their trip, and it was also the place where he and Su Lan's parents had stuck to the Great Wall of Life.

In the old Yuan era, the earth was full of human cities, the population once reached 10 billion, and the developed science and technology penetrated into every corner of the world, which was called the era of great prosperity by the survivors of the new Yuan era.

Taoism has a saying that prosperity must decline.

The era of chaos has suddenly arrived.

Starting from the Arctic, many unbelievable and bizarre events have occurred around the world, giving rise to many xenomorphic creatures that cannot be explained by science, frantically attacking human society.

Then war broke out, the world fell into chaos, and human society was on the verge of collapse, almost turning into a wasteland. Until the appearance of the Great Wall of Life, which preserved the flame of human civilization, and after more than 200 years of long recovery, with the cultural and intellectual wealth handed down by the ancestors, many larger cities were established one after another.

With the advent of the New Era, mankind has abandoned prejudices between races and united in all aspects for the continuation of civilization. Since then, the concept of the state has become blurred, collectively known as the Community of Human-Destiny (CHD), and all people are the spark of human civilization.

In order to commemorate the great Chinese civilization, the cities established by the descendants of Yan and Huang are named after the more prosperous dynasties in the old Yuan period, Xiacheng, Shangcheng, Zhoucheng, Qincheng, and Hancheng were the earliest, with the largest population and the most prosperous, and Weicheng, Jincheng, Suicheng, and Tangcheng were established a little later, and the population was relatively sparse, but the technology and industry were leading. Most of the Songcheng, Yuancheng, Mingcheng, Qingcheng, and Zhonghua City are in the stage of infrastructure construction and drawings.

Lu Yuan and Su Lan have lived in Ganlin City, Qincheng since they were children, and have never stepped out of the city, to be precise, all children are strictly forbidden to be within twenty kilometers of the Great Wall of Life until they are eighteen years old.

Lu Yuan asked his father what the outside world was like. Then, his dad lifted his prosthetic leg and lovingly ** his head, sighing and shaking his head.

Dad didn't tell him what the outside world was like in the end, but Lu Yuan knew that Dad's arm was lost in the outside world.

and Su Lan's father, when she was three years old, lost in the outside world and never came back.

Therefore, he is both curious and afraid of the outside world.

But now, whether he wants it or not, he and Su Lan must follow the life trajectory of their parents, face the world they should face, and fight for the survival of future generations for the rest of their lives.

"Oops. ”

Walking past the Huiwen Bookstore on the corner, Su Lan in front of him suddenly screamed in pain, and the whole person staggered, almost falling to the ground.

Lu Yuan hurried over a few steps, and saw the high heels she was wearing, the heels happened to be stuck in the cracks of the broken bricks, he couldn't help but laugh and said, "Make you stinky and beautiful, little kid students wear high heels, it's cool, right?"

With a snap, Su Lan opened his hand, tears of pain swirled, and hummed: "Get out of the way, I don't need you to care......!" It hurts. ”

"Don't move!" Lu Yuan didn't care about her obstruction, reached over again, held her ankle with one hand, and held the heel of her shoe with the other, and carefully pulled it out.

"The heel is cracked, and if you wear it again, you will have to fall!"

"You don't care! Don't touch my feet!" Su Lan pushed on his chest, but he didn't want Lu Yuan to be in a half-squatting position, and he couldn't use the force under his feet, so he fell on his back.

With a bang, the back of his head hit the ground, and there were little stars in front of him, twinkling and shining.

Su Lan's expression tightened, his eyes showed a little panic, and he blurted out, "Are you okay......?" I didn't mean to. ”

Lu Yuan covered the back of his head, bared his teeth and said, "No, it's a concussion." I need my sister to kiss me before I can get up. ”

"Get out of you!" Su Lan snorted, and a smile condensed on her right cheek, and at that moment, she was like a pear blossom blooming, beautiful and moving. However, this coquettishness only lasted for half a second, and then it stopped, and it turned into indifference again.

Lu Yuan stood up lazily, rubbed the back of his head, and said, "Be kind to treat it as a donkey's liver and lungs, and I don't bother to care about you." ”

Fortunately, there were spare shoes in the suitcase, Su Lan rubbed his ankles for a while, then opened the suitcase and took out a pair of sneakers. As I was changing my shoes, the mobile phone in my pocket suddenly rang.

The moment he saw the caller number, two faint blush suddenly appeared on his cold face, and his eyes showed a look of surprise, and he subconsciously wanted to answer, but he paused suddenly.

Lu Yuan glanced at it and frowned slightly.
