Alien Knights

Great freshmen, hello. My surname is Xia and my name is Shang. I am a visiting associate professor of life engineering. This afternoon, I am very happy to give you a lecture on Basic Theory of Biochemistry.

In the back row of the lecture theater, 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-rimmed mirror and a neat suit was not at all annoyed, and smiled slightly: Of course, if you can write down the chemical structure of the antidote to the T virus...

Turning around and writing words such as virus, bacteria and parasite on the blackboard, Xia Shang turned his head and said to the students: Let's talk about the subject of the biochemical game that this student said. Let's take a look at the commonly used terms in these biochemical weapons. Isn't it scary? But the reality is that quite a few of these creatures, not only do not harm the human body, but can actually benefit the human body. For example, bacteriophages, which are viruses, are different from antibiotics that attack bacteria randomly. They can attack specific pathogenic bacteria; another example is parasites. Although their existence is not necessary for a healthy body, it can play a key role in certain diseases.

Another boy raised his hand and asked, Teacher! Is it possible that the superpowers in movies and novels that appear due to viruses or bacteria are real?

As if he didn’t expect someone to ask such a question, Xia Shang lowered his head and thought for a while, then drew a two-dimensional coordinate axis on the blackboard. While drawing a curve similar to a “downhill” on the coordinates, he said to the students in the audience: “The X-axis is time, and the Y-axis is quantity. Throughout human history, viruses, bacteria, parasites and other microorganisms or xenobiotics, with the advancement of medicine, changes in the human body and the reduction of species, their number and type have always been on a downward trend.”

A study shows that by 2070, it is estimated that 30% of the existing parasites will disappear. So, let's make an interesting assumption. Looking at the origin of a thousand years ago, when biological species were more complete, such as the early Middle Ages in Europe, the types of microorganisms and heterogeneous organisms may be several times more than in modern society. From the perspective of probability, there is indeed a high probability that there will be organisms that change body functions and even trigger supernatural abilities...

Xia Shang thoughtfully tapped the podium with chalk, and continued: If the biochemical technology reached today's level at that time, under the deliberate drive of ambitious people, it might even really change the course of history... Well, let's get far away! Let's stop talking and go straight to the topic of the lecture. First, I plan to talk about proteins and nucleic acids...

On the middle tip of the moon, the night is like water.

Anxi Road, in front of Suyuan Hotel.

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

Walking on the deserted street, he let out a long breath.

The night wind blew by, his stomach was churning, Xia Shang staggered, sat down on the road, bent over and retched.

Look up again.

A blinding light, a sudden brake.

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

The harsh siren of the ambulance, the shouting of people next to the ear, the ticking of the machine when it is running.

Xia Shang's consciousness gradually separated from his body.

——————————————

After an unknown amount of time, Xia Shang woke up from his sleepiness.

With his eyelids twitching, his eyes opened slightly, the things in his vision were blurred, and everything in front of him seemed to be covered with a tulle.

Blinking hard, his vision finally became a little clearer.

On the simple wooden table stands a flickering candle covered with a simple windshield. The lower part of the body is covered with straw, and the face is facing the dark roof. The sour smell of rotting meat can be faintly smelled in the nose.

where is this Hospital?

Puzzled, Xia Shang tried to take a deep breath while lying flat, but unexpectedly, a foreign object in his mouth suddenly fell into his trachea and got stuck in the middle of his throat.

Breathing suddenly became extremely difficult. He rolled on the haystack in pain, and tried his best to buckle his fingers into the throat, but he couldn't reach it.

The long-term lack of oxygen made Xia Shang's brain tingle, but it made his thinking slowly begin to clear up.

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

Hai... Heimlich first aid method!

One turned over and fell to the ground, Xia Shang crawled to the side of the wooden table. He knelt down beside the table with all his strength, pressed the hard corner of the wooden table above his navel, put one hand into a fist between the wooden table and the skin, and pushed the other hand toward the upper part of the chest.

once.

twice.

three times.

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

After going around the gate of hell and finally returning to the world, Xia Shang calmed down and looked at the black foreign object on the table with the faint light of the candle. The black jelly-like object smelled like a pungent medicinal herb.

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

Originally a 28-year-old mature man, his body turned into a boy! Coupled with a medieval dress of coarse linen corset, and a wooden cross on the chest.

Crossed?

crossed...

Covering his face with his hands in distress, Xia Shang pulled out his hair vigorously.

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, and the character he had cultivated through long-term scientific research allowed him to gradually regain his composure.

First, three things need to be clear.

who I am? !

where am i !

what happened? !

Hold up the candle on the wooden table and look around.

A closed small room with a small window under the roof and a wooden door leading to the outside. There was a wooden table, a pile of straw, a small pile of coal, and a stone stove that looked like wood for heating. The chimney of the stove forked in two ends, one through the roof and the other through the wall to the next room.

Xia Shang tried to push the door with both hands, but the wooden door didn't move at all. He squatted down and looked, and a solid iron pin locked the door from the outside.

Reluctantly turning around and coming back, he set his sights on the tall small window. He pulled the wooden table under the window, stepped on the table and climbed up, then stood on tiptoe, barely reaching the window with his forehead. Pushing away the baffle covered with thick animal skin, 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 and violent wind in your ears.

Comparing the size of the window with his hands, and then looking at the width of his shoulders, Xia Shang quickly gave up the idea of ​​escaping through the window. Besides, in such a big snowstorm, even if you go outdoors, you can't walk a few steps, and people will be frozen into popsicles.

After closing the window, he tightened the thick linen robe around his body, and began to think about other escape methods...

At this moment, there was a heavy revolving door sound from the next room.

A burst of bone-chilling frost followed the floor and penetrated into the small room through the gap under the wooden door.

Xia Shang unconsciously shuddered deeply and shrank his body back.

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

A sharp, nasal voice sounded.

Damn blizzard!

Another husky voice, which sounded like a blunt knife on glass, followed up: Hudgens is late.

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

This horrible weather! It would be strange if he showed up on time!

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

Carefully crawling towards the door, Xia Shang narrowed his eyes to observe the movement in the next room.

Under the light of the shaking candles, a bearded man's face was facing the direction of the door, and a pair of leopard eyes deeply embedded in the eye sockets met the boy's gaze.

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

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

The hunchback untied the noose and dagger hanging from his waist, looked inward along the direction, and said, Poor little Todd, he even gave me a bracelet made of bells and flowers...

Put away your useless face, isn't it you who poured poison into his mouth just now?

Hearing Leopard's Eye's merciless accusation, the hunchback shrugged, and said in a nonchalant tone: There's no way, who told him to see something he shouldn't see.

Tomorrow morning, we have to dispose of that corpse!

I know, I know, as usual. In sacks, in mines...

Don't forget the finishing work!

The leopard-eyed man muttered a few words and blew out the candle.

The sound gradually disappeared in the darkness, and there were only two voices left in the narrow cabin.

The sound of the snoring of an outlaw murderer, the heartbeat of a lamb waiting to be slaughtered.

A new book is uploaded, begging for attention. Caring for seedlings starts with me.
