"Hello, freshmen students. My surname is Xia Mingshang, and I am a visiting professor in the life engineering major of our school. This afternoon, I am very happy to give you a lecture on "Biochemistry". Before officially starting, I would like to ask
,Has anyone ever been exposed to this subject?”
From the back row of the lecture theater, a boy's voice came: "Teacher, I have cleared all "Resident Evil", does this count?"
On the podium, the elegant man wearing black-framed glasses and a neat suit was not angry at all. He laughed and said, "Of course, if you can write down the chemical structure of the antidote to the T virus..."
Turning around and writing "virus", "bacteria", "parasite" and other words on the blackboard, Xia Shang turned back to the students and said: "Let's talk about the theme of the biochemical game that this classmate mentioned. Look, everyone."
Isn’t it scary to look at these common terms used in biological and chemical weapons? But the reality is that quite a few of these creatures
Not only do they not harm the human body, they can actually benefit the human body. For example, phages, which are viruses, are different from antibiotics that attack bacteria at will. They can attack specific pathogenic bacteria. Another example is parasites. Although their existence has no impact on a healthy body,
It is necessary, but it can play a key role in some specific diseases."
Another boy raised his hand and asked: "Teacher! Is it possible that the superpowers that appear due to viruses or bacteria in movies and novels are real?"
As if he didn't expect that someone would ask such a question, Xia Shang lowered his head and thought for a while, then drew a two-dimensional coordinate axis on the blackboard. He used chalk to draw a "downhill" curve on the coordinates, while
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 quantity and variety have been on a downward trend."
"A study shows that by 2070, 30% of existing parasites are expected to disappear. So, let's make a very interesting hypothesis. A thousand years ago, biological species were more complete.
In historical periods, such as the early Middle Ages in Europe, the types of microorganisms and xenobiotics may be several times greater than in modern society. From a probability perspective, there is indeed a high chance that organisms that change body functions will appear...
"
Xia Shang thoughtfully tapped the podium with a piece of chalk and continued: "If biochemical technology had reached today's level at that time, with the intentional drive of ambitious people, it might even really change the trajectory of history... okay
, I’m going too far! Let’s stop chatting and go directly to the main topic of the lecture. First, I plan to talk about proteins and nucleic acids..."
The moon is at its peak, and the night is like water.
Anxi Road, in front of Suyuan Hotel.
Just after a dinner party, Xia Shang smiled and declined the invitation from his friends to extend the stall, gave up driving, and planned to walk to the school's biology laboratory to see the strains in the petri dishes.
Walking on the deserted street, he sighed softly.
The night wind blew by, and his stomach was churning. Xia Shang stumbled, sat down on the road, bent over and retched.
Look up again.
There was a dazzling light and a sudden brake.
The severe pain was like ink dripping into clear water, swelling and soaking from the chest.
The piercing siren of the ambulance, the shouts of people next to my ears, and the ticking of machines running.
Xia Shang's consciousness gradually left his body.
——————————————
I don't know how long it took before Xia Shang woke up from sleepiness.
His eyelids twitched, and he opened his eyes slightly. The things in his field of vision were blurred, and everything in front seemed to be covered with gauze.
Blinking hard, my vision finally became a little clearer.
On the simple wooden table stood a candle with a simple windshield, which flickered on and off. The bottom of his body was covered with wheat straw. His face was facing the dark roof, and he could vaguely smell the smell of rotting meat in his nose.
The sour smell.
Where is this? Hospital?
The puzzled Xia Shang lay down and tried to take a deep breath. 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 in pain on the haystack and tried desperately to dig into his throat with his fingers, but he couldn't reach it.
The long-term lack of oxygen made Xia Shang's brain tingle, but his thinking slowly began to become clearer.
Is there any way to get this thing out of my throat?!
Ha...Heimlich maneuver!
Turning over and lying on the ground, Xia Shang crawled to the wooden table. He knelt down beside the table with all his strength, pressed the hard corner of the wooden table above his navel, and put a fist on the wooden table and his skin.
In the meantime, push the other hand toward the upper part of the chest.
once.
twice.
three times.
The air in his chest rushed toward his mouth, and with a violent cough, a black semi-solid object the size of a baby's fist was spat out from his mouth.
After going around the gate of hell and finally returning to the world, Xia Shang calmed down his breathing and looked at the black foreign object on the table with the faint light of the candle. The black jelly-like object smelled of a pungent herbal odor.
Soon, looking at his young and thin hands under the candlelight, he discovered an even more shocking fact.
The mature man who was originally 28 years old has turned into a teenager! Coupled with the medieval dress of a coarse linen corset and a wooden cross on his chest.
Traveled through time?
Traveled through...
Covering his face with both hands in distress, Xia Shang pulled out his hair vigorously.
Although I have seen similar plots in novels and movies, when it actually happened to me, the first thing that came to my mind was helplessness and despair.
It took him a few minutes to calm down. The character he had developed through long-term scientific research work gradually helped him regain his composure.
First, we need to understand three things.
who I am?!
Where am I?!
what happened?!
Lift the candle on the wooden table and look around.
A small closed room, a small window opened under the roof, and a wooden door leading to the outside. There is a wooden table, a pile of wheat straw, a small pile of coal, and what looks like a firewood heater in the room.
The chimney of the stone stove is bifurcated into two ends, one end goes through the roof, and the other end goes through the wall to the next room.
Xia Shang tried to push the door with both hands, but the wooden door did not move at all. He squatted down and looked, and saw that a strong iron pin locked the door from the outside.
Reluctantly, he turned back and focused his gaze on the small high window. He pulled the wooden table under the window, climbed up on the table, stood on tiptoes, and barely reached the window with his forehead. He pushed open the thick curtain
Looking out at the thick animal skin baffle, the violent wind and snow have invaded the outside world into a vast expanse of white. Looking far into the distance, I can't see the scenery and boundaries in the distance. I can only hear the roaring and violent wind.
.
Comparing the size of the window with his hand, and then looking at the width of his shoulders, Xia Shang quickly gave up the idea of escaping from the window. Besides, in such a heavy snowstorm, even if people can't walk a few steps outdoors, they will be trapped.
Freeze into popsicles.
After closing the window, he tightened his thick linen robe and began to think of other ways to escape...
At this moment, a heavy revolving door sound came from the next room.
A gust of biting frost and snow followed the floor and entered the small room through the gap under the wooden door.
Xia Shang shivered deeply unconsciously and shrank his body back.
Someone lit the candle in the next room, and a faint light slowly shone in through the crack in the door.
A sharp, nasal voice sounded.
"Damn blizzard!"
Another hoarse voice that sounded like a dull knife scraping against glass followed: "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 without any effort even though he had never heard it before.
"This kind of weather! It would be strange if he showed up on time!"
His high-pitched voice was full of disdain for "Hudgens", and he threw his coat, which was covered in frost and snow, heavily on the ground.
Xia Shang carefully crawled towards the door and aimed his eyes at the gap in the door panel. Xia Shang squinted his eyes and observed the movement in the next room.
Under the illumination of the flickering candle, a bearded man's face was facing the direction of the door panel, and a pair of leopard eyes deeply embedded in the eye sockets met the young man's gaze.
The blood in his veins seemed to have solidified. The horrified Xia Shang covered his nose and mouth with both hands, trying his best not to make any sound.
The leopard-eyed man stared at the door panel for a while, and finally shifted his gaze to the hunchbacked companion beside him. He slid his thumb towards the room where Xia Shang was, and the hoarse voice sounded again: "What should I do about the one inside?"
The hunchback took off the noose and dagger hanging from his waist, looked in the direction, and smashed his mouth: "Poor little Todd, he also gave me a bracelet made of bell flowers...
"
"Put away your useless face. Weren't you the one who poured poison into his mouth just now?"
Hearing Leopard Eye's merciless accusation, Hunchback shrugged and said in a nonchalant tone: "There is no way, who told him to see something he shouldn't have seen."
"We have to get rid of that body early tomorrow morning!"
"I know, I know, just like usual. Put it in a sack and throw it into the mine..."
"Don't forget to clean up!"
The leopard-eyed man muttered something and blew out the candle.
The sounds gradually disappeared in the darkness, and there were only two voices left in the narrow cabin.
The snoring of outlaw criminals and the heartbeat of a lamb waiting to be slaughtered.
