Alien Knights

"Hello, freshman classmates. My surname is Xia Mingshang and I am a visiting professor of life engineering in our school. This afternoon, I am very happy to give you a biochemistry lecture. Before the official start, I would like to ask someone Have you ever been exposed to this subject?"

　　 In the back row of the lecture hall, a boy's voice came: "Teacher, I have cleared all the "Resident Evil", does this count?"

　　 On the podium, the elegant man wearing a black frame mirror and a neat suit was not at all annoyed. He laughed and said, "Of course, if you can write the chemical equation of the T virus..."

Turning around and writing the words "virus", "bacteria", "parasites" on the blackboard, Xia Shang turned around and said to the students: "Let's talk about the subject of biochemical games that this student said. Let's see. Looking at the commonly used terms in these biological and chemical weapons, is it scary? But the reality is that a considerable part of these creatures not only do not harm the human body, but can produce benefits to the human body. For example, bacteriophages, which are viruses, attack bacteria at will with antibiotics. Different, it can attack specific pathogens; another example is parasites. Although their existence is not necessary for a healthy body, they can play a key role in certain diseases."

　　 Another boy raised his hand and asked, "Teacher! Is it possible that the superpowers that appear in movies and novels because of viruses or bacteria are true?"

It seemed that he didn't expect that someone would ask such a question. After Xia Shang bowed his head and thought about it, he drew a two-dimensional coordinate axis on the blackboard. While he drew a curve similar to "downhill" on the coordinate, he used chalk on the coordinate. Said to the students in the audience: “The X axis is time, and the Y axis is quantity. Throughout human history, microorganisms or xenobiotics such as viruses, bacteria, and parasites, with the advancement of medicine, the change of the human body, and the decrease of species, Its number and species have been on a downward trend. A study shows that by 2070, 30% of the existing parasites are expected to disappear. So, let’s make a very interesting hypothesis. Thousands of years ago, in the more complete historical period of biological species, such as the early Middle Ages in Europe, the types of microorganisms and xenobiotics may be several times greater than that of modern society. From a probabilistic point of view, there is indeed a high probability. , There will be creatures that change bodily functions..."

Xia Shang thoughtfully tapped the podium with a chalk, and continued: "If biochemical technology reached today's level by then, driven by the ambitions, it might even change the trajectory of history... well, Far away! Let’s not gossip and go directly to the main topic of the lecture. First of all, I intend to talk about protein and nucleic acid..."

　　The middle shoots of the moon, the night is like water.

　　Anxi Road, in front of "Suyuan Hotel".

　　 Just after a meal, Xia Shang smiled and refused the invitation of his friends to renew the stall, gave up driving, and planned to walk to the school's biological laboratory to see the strains in the petri dish.

　　Walking on the empty street, he sighed softly.

　　 The night wind blew, and the stomach was tumbling to the sea, Xia Shang staggered under his feet, sitting down on the road, bending over and retching.

　　 raised his head again.

　　 A dazzling light, a sudden brake.

　　 The severe pain is like ink dripping into clear water, rendering it soaked from the chest.

　　 The ear-piercing whistle of the ambulance, the yelling of people next to the ear, the ticking of the machine when it is running.

　　 Xia Shang's consciousness gradually separated from the body.

　　———————

　　 I don’t know how long it took, Xia Shang woke up from sleepiness.

　　 He twitched his eyelids, his eyes opened slightly, things in his vision were blurred, and everything in front of him seemed to be covered with tulle.

　　 blinked his eyes vigorously, his vision finally became a little clearer.

On a simple wooden table stood a light and dark candle covered with a simple windshield. The underneath of the body was covered with wheat stalks, and the face was facing the dark roof, and there was a vague smell of rotting meat in the nose. The sour smell.

　　 Where is this place? Hospital?

　　The puzzled Xia Shang tried to take a deep breath while lying flat, but he didn't expect a foreign object in his mouth to suddenly fall into his trachea and get stuck in the middle of his throat.

　　 Breathing suddenly became extremely difficult, and he was rolling in pain on the haystack, using his fingers desperately to buckle into the throat, but he couldn't reach it.

　　 Prolonged lack of oxygen made Xia Shang's brain sting, but his thinking slowly began to become clear.

　　 Is there any way to get this thing out of your throat? !

　　 sea... Heimlich first aid!

　　 rolled over and fell on the ground, Xia Shang crawled to the side of the wooden table. Kneeling down at the table with all my strength, pressing the hard corner of the wooden table against my belly button, placing a fist with one hand between the wooden table and the skin, and pushing the other hand toward the upper part of the chest cavity.

once.

　　 twice.

　　 three times.

　　 The air in his chest rushed towards his mouth. Along with a violent cough, a black semi-solid object the size of a baby's fist was spit out from his mouth.

　　 After going around the ghost gate and finally returning to the world, Xia Shangping recovered his breath and looked at the black foreign object on the table with the faint light of the candle. The black color resembled a jelly-like object, and it smelled of a pungent medicinal stench.

　　 Soon, under the candlelight, looking at his thin and thin hands, he discovered an even more shocking fact.

　　 The 28-year-old mature man has turned into a boy! Coupled with a medieval dress in a hemp corset, and a wooden cross on the chest.

　　 Crossed?

　　 crossed...

　　 covered his face in distress with both hands, Xia Shang pulled out his hair forcefully.

　　 Although I have seen similar plots in novels and movies, when it really happened to me, the first thing that came to my mind was helplessness and despair.

　　 It took a few minutes to calm down his mind, and the temperament he had cultivated through long-term scientific research helped him gradually regain his composure.

　　 First of all, three things must be figured out.

who am I? !

　　 Where am I? !

what happened? !

　　 raised the candle on the wooden table and looked around.

　　 A small closed room, a small window opened under the roof, and a wooden door leading to the outside. In the room there is a wooden table, a stack of wheat stalks, a small pile of coal, and a stone stove that looks like wood for heating. The chimney of the stove is forked at two ends, one through the roof and the other through The wall reaches the next room.

　　 Xia Shang tried to push the door with both hands. The wooden door didn't move. He squatted down and saw that a strong iron pin locked the door from the outside.

　　 reluctantly turned back and placed his gaze on the tall small window. He pulled the wooden table under the window, stepped on the table and climbed up, and then stood on his toes, his forehead barely reaching the window. Pushing open the baffle covered with thick animal skins, looking out, the violent wind and snow invaded the outside world into a vast expanse of whiteness. Looking far away, you can't see the distant scenery and boundaries, and you can only hear the whistling. A violent wind.

　　 Compared the size of the window with his hand, and then looked at the width of his shoulder, Xia Shang quickly gave up the idea of ​​escaping through the window. Besides, even in such a big snowstorm, people will be frozen into popsicles even if they cannot walk a few steps outdoors.

　　 closed the window, he tightened his thick linen robe, and began to think about other ways to escape...

　　 Just then, there was a heavy turning door in the next room.

　　 A burst of icy frost followed the floor, from the gap under the wooden door, into the small room.

　　 Xiashan shuddered unconsciously and shrank back.

　　 Someone lit the candle in the next room, and a faint light slowly reflected in through the crack of the door.

　　 A sharp, severe nasal voice sounded.

　　 "Damn blizzard!"

　　 Another hoarse voice that sounded like a blunt knife scraping the glass followed: "Huggins is late."

　　 Xia Shang held his breath and listened intensively to the conversation between the two in the outbuilding. What surprised him was that he could understand the meaning of a language he had never heard before without any effort.

　　 "This kind of spooky weather! If he can show up on time, that would be a weird thing!"

　　 The sharp voice was full of disdain for "Huggins", and he threw the frost-stained coat on the ground.

　　 carefully crawled to the door, UU reading www.uukanshu.com aimed his eyes at the gap in the door panel, Xia Shang squinted his eyes and observed the movement of the next room.

　　 Under the shining of the shaking candle, a bearded man's face was facing the direction of the door panel, and a pair of leopard eyes embedded in the eye sockets met the sight of the boy.

　　 The blood in his veins seemed to have solidified, and Xia Shang was terrified, covering his nose and mouth with his hands, trying his best not to make any noise.

　　 The leopard-eyed man stared at the door panel for a long time, and finally shifted his gaze, looked at the humpbacked companion beside him, slid his thumb to the room where Xia Shang was, and his hoarse voice sounded again: "What should I do with the one inside?"

　　 hunched back and untied the noose and dagger hanging around his waist, looked in the direction, and smashed his mouth: "Poor little Todd, he even gave me a bracelet made of bells..."

　　 "Put away your useless face and pouring poison into his mouth just now, isn't it you?"

　　 Hearing Leopard Eye’s merciless accusation, he hunched back and shrugged, and said in an indifferent tone: “Then there is no way, who told him to see something he shouldn’t look at.”

　　 "Tomorrow early in the morning, we have to get rid of that corpse!"

　　 "I know, I know, as usual. Put it in a sack, throw it into the pit..."

　　 "Don't forget the finishing touches!"

"Oh my God, you are so long-winded! Stripping off clothes, smashing faces, burning hair, these tasks don't need you to remind me, I am not a novice! Can I sleep for a while after busying all night? I'll talk about it tomorrow!"

　　 The leopard-eye man murmured a few words and blew out the candlelight.

　　 The sound gradually disappeared in the darkness, and only two voices remained in the narrow cabin.

　　 The snoring sound of a criminal outside the law, the heartbeat of a lamb to be slaughtered.
