In the realm of the future world, the status of energy elixirs is equivalent to important resources such as silver bones and putrid hormones. It can even act as a currency.

This biochemical agent can replenish the body's energy in a short period of time, quickly repair damaged nerves and muscles, form protection in damaged parts of the body, accelerate cell division, and promote a series of hormones in the body.

In terms of the stimulating effect of the nervous system alone, it is similar to the effect of stimulants. However, the most important role of energy potions is not limited to this. It has a significant effect on cell repair in damaged areas and has no side effects on the brain and central nervous system.

"A bottle of energy potion can save your life in the most dangerous time."

This is a well-known proverb in the world of the future.

It has a very wide range of uses. Even the least effective "D" potion can still repair broken internal organs and pull the dying back from the brink of death. In short, the difference between a low-level potion and a high-level potion is only the recovery effect of different time stages.

Advanced flasks recover quickly and take a short time.

Lower-grade potions take longer. It could be an hour, or even a few days.

The lab is well lit, with large and small test tubes and glassware on the workbench. Together with the various instruments arranged in sequence along the walls, they form a dense and complex but orderly and serious atmosphere.

When Su Hao walked into the room, Zhou Chen was sitting quietly on the swivel chair, looking at an open measuring cup in front of him in a daze.

"I made this according to the recipe in the USB stick."

Zhou Chen stared at the measuring cup intently, slightly divided his gaze to look at Su Hao's figure reflected on the surface of the glass, and said lightly: "I don't know what this is." I'm not sure. ”

This strange incoherent speech made Su Hao feel puzzled.

He walked to the opposite side of the workbench and looked at Zhou Chen's face with a frown———— this young man in a white coat had a pale complexion, a stiff expression, and his eyes were slightly distracted.

Su Hao stared at him with a keen gaze: "What's wrong with you?" ”

Zhou Chen's face was a little gloomy, and a strange gaze was released in his pupils. He leaned forward, almost entirely on the table. Hold the measuring cup with the fingers of both hands, and bring your head close. Through thick glass glasses, he looked greedily at what he held in his hand like a miser looking at a diamond.

The measuring cup contains some dark black liquid. It's cloudy and looks like ink.

"This is the result of the research that took me nearly three months to develop. Well, to be precise, it should have taken three months to do basic research, and it failed many times. It wasn't until this morning that it was very fortuitous and unexpected, and it should have been a fluke that made a breakthrough. ”

Su Hao looked at Zhou Chen carefully.

There is a mysterious connection between the black particles that enter the bodies of other injectors and the mother.

This could be a latent organism in the human body, or it could be a prototype agent that creates sensory consciousness between cells. With this kind of thinking perception that is more accurate than fingerprints and genes, Su Hao clearly knew that the man sitting in front of him ———— was indeed Zhou Chen, not an imposter with a similar appearance.

After confirming this, Su Hao's vigilance and vigilance also dissipated mostly. He pulled a chair from the side and sat down, and asked strangely, "What do you want to tell me?" ”

Zhou Chen slowly raised his head, he put away his strange gaze, making the whole person look slightly normal, but his voice was still hoarse: "I created an energy potion." ”

Su Hao's face froze, and he subconsciously focused his gaze on the glass measuring cup containing the black liquid.

As a person who has crossed over from the future realm, it is certainly impossible for Su Hao to forget the words "energy elixir".

However, the liquid in front of him had nothing to do with the energy potion in his memory. Because they're mostly blue and purple, not the pitch black that seems so easy to associate with words like "dirty."

"You said that according to the length of recovery time and different effects on the damaged parts, energy potions are divided into four qualities: A, B, C, and D."

Zhou Chen's voice sounded like a woman moaning after being violent.

"I configured it according to the information in the USB flash drive. Last week, I took six 95 percent of the culture and injected them into a few mice that had had their livers cut off. It took four days for these poor little ones to recover. Judging from the effect and time, this extract should be a "D" grade energy potion. I don't have autoclave equipment, and I can't get a mass production line. It is difficult to obtain the chemical solution by bacterial culture, and the quantity is not large. Under normal circumstances, a maximum of about 50 milliliters can be produced in a week. You know, the concentration of the medicine has a proportional relationship with factors such as human height and weight. For the best recovery results, the number of doses should not be less than 20 ml at a time. This is also the minimum volume of a single vial."

Su Hao coughed, interrupting Zhou Chen's chatter: "Talk about the point." ”

"The point?"

His voice changed instantly, and he looked excited, as if he had been injected with a large amount of male hormones, and he happened to see the hungry man in the color of the big-breasted ** beauty: "I have thought about it carefully———— since I can't improve the quantity, then I can only think of a way from the quality." ”

Su Hao's eyes trembled slightly.

Even in the future realm, the recipe for a high-quality energy potion is a secret secret. That's not at all based on the "D" grade pharmaceutical formula, and the number of raw materials can be added to achieve the qualitative change standard. Su Hao was a researcher at the Academy of Sciences at the time, and he vaguely knew the raw materials needed for some "C" grade medicines. It is completely different from the "D" grade pharmacy, many ingredients and strains need to be accurately proportioned, and it is impossible to deduce and explore through the "D" grade culture.

Sure enough, Zhou Chen's next words confirmed his guess.

"I increased the number of variant 3 and quadrupled the amount of myophytic solution. Hehe! You know, we have a lot of putrefactive hormones, and I increased the amount of this stuff by 40 percent per 100 milliliters of culture stock and guess what? ”

Su Hao smiled bitterly and shook his head: "A cup of poison that dies when you touch your lips?" ”

"Sort of!"

Zhou Chen grinned, a mouthful of white teeth glaring in the light: "That's a dark purple potion." I picked a particularly fat mouse. Unfortunately, it didn't recover as I expected, and it turned into a puddle of pus. Well, I know there's something wrong with the recipe. But there was no more information on the USB stick, and there were no samples to refer to. The point is good! I said———— I got ten milligrams of your blood and added it to the culture to see if there would be any chemical reaction. The dark purple liquid instantly turned black before my eyes, spreading throughout the petri dish like a plague. It's a pity that I didn't have a camera at the time, otherwise I would have been able to capture my own horrible expression. Here! It was this, my accidental, or rather miraculous manifestation. ”

"Miracles?"

"Definitely ————"

As he spoke, Zhou Chen, who looked a little crazy, picked up the measuring cup and handed it to Su Hao: "The recovery effect of this thing is definitely beyond your expectations." The mouse, which I had gutted out, regained its mobility in less than a minute. I even saw its heart and intestines regenerate. Not! It was disgusting, but exhilarating! ”

Su Hao took the measuring cup, his expression was puzzled.

He smelled a faint stench. It's like stir-fried meat that doesn't have a refrigerator in the fridge on a hot day and goes rancid outside overnight. It's not pungent, but it's there, and it's impossible to ignore.

Su Hao's memory energy potion is definitely not like this.

According to the order of D to A, the colors of the potions are light blue, light red, dark blue, and dark purple. The smell is similar to that of a certain medicated toothpaste, and it is not unpleasant, let alone like these black things in the cup in front of you, which makes you feel disgusting to look at.

"That's what you call a miracle?"

Su Hao's brows became tighter and tighter: "You must associate this thing with "God", I'm afraid it should be God's vomit or excrement." ”

Zhou Chen didn't seem to hear the sarcasm in his words, his eyes lit up, and he pouted expectantly: "Take a sip and try it, it tastes good." ”

Su Hao's eyes widened, and he asked in disbelief, "Have you ever drunk?" ”

Zhou Chen shook his head and confessed: "No, that mouse has drunk." ”

"And you're still telling me to drink?"

"I've tested the specific ingredients and it's not poisonous. This stuff is produced in small quantities, and you're actually the best test subject to be safe. I have to record all your physiological reactions after taking it as a reference for improving the formula."

The gaze in Zhou Chen's eyes was infinitely pure, exuding a strong "worker bee" atmosphere.

Su Hao made sure again———— he didn't mean to harm himself, and he didn't lie.

This cup of black liquid may indeed have the miraculous effect that Zhou Chen said. But Su Hao couldn't drink it.

It's disgusting.

It's like eating too much chili pepper, excreting from the anus, very thin.

The two of them were at a stalemate.

A full of anticipation.

One looked embarrassed.

"Didi ————"

Suddenly, the portable intercom on Su Hao's waist lit up red. He quickly took out the microphone as if relieved, pressed the call button, and immediately heard Dong Guoping's anxious voice in his ears.

"Boss, I'm at the No. 1 gas station. You'd better come over and see something. ”

When Su Hao drove into the gate of the No. 1 gas station, Dong Guoping was directing the workers to put a 12. The 7-mm heavy machine gun was mounted on a crane on the guard tower.

They are very familiar with each other, and they don't need any polite words. Dong Guoping directly took Su Hao into the small room behind the gas station for dissecting zombies.

A new ventilation fan was installed in the room, and the triangular paddle wings were constantly spinning, but there was always a faint smell of blood in the air.

On the bloodstained wall, two zombies hang.

They had been hit hard in the head and had been dead for a long time. In order to facilitate the dissection, Dong Guoping still fixed the limbs of the zombies with nails, buckled the necks with iron rings, and spread their bodies into a standard "big" character.

Su Hao walked up to the nearest zombie.

Judging by its tattered clothes, it was once a male human. Very thin, but about twenty centimeters taller than other zombies. His hair was almost gone, his worn-out trousers were rotten to his knees, and his clothes were hard to distinguish.

None of this is the point.

Su Hao pulled out the dagger from his waist and cut his clothes and pants along the zombie's shoulders and waistline, revealing a dark red body.

That's right! Dark red———— it has the same color on all the skin on its body, like the kind of soil that is unique to the highlands. The face, arms, chest, abdomen, and thighs are not as gray as the other zombies, and there is very little pus on the surface of the body, but the skin on the wrists, legs and feet has obvious tear marks.

Dong Guoping pointed to the wound on the zombie's left shoulder that was cut by a knife, and said, "It's strange that its muscles are not rotten. It's very tight, not as thin as other zombies. There was even a small amount of blood in the body during the dissection. This has happened to other zombies before. ”

Su Hao nodded noncommittally and asked, "Where did you find it?" ”

"It's coming along the road outside."

Dong Guoping's voice was calm: "Its movements are more flexible than other zombies, and its speed is also faster." Initially, the guards believed that it was not a zombie, but that it might be a survivor of some mental disorder. It was only when I got closer that I realized that I had made a mistake in judgment. That shot was accurate, straight through the head. ”

As he spoke, he raised his hand and pointed to the bullet holes on the top of the zombie's head that had been blocked with black blood and shredded flesh.

Su Hao didn't speak, and took his gaze away from the dark red zombie and shifted it to another zombie next to him.

It likewise wears tattered clothes, and there is nothing noteworthy about its body, limbs, and skin. It's just that the head was cut off, hung from both sides with an iron hook, and hung in the air more than a meter above the ground.

"This was found outside the fence yesterday afternoon."

Dong Guoping stepped forward and used a knife to remove the weeds and hair on the top of the zombie's head, revealing two abnormal protrusions extending from the arch of his eyebrows to the top of the body.

The two protrusions are about five centimeters long, the thickness of an adult's fingers, and the color is similar to that of the skin, which is very elastic. Su Hao flicked it with the tip of the knife, and the meat pillar immediately swayed from side to side like a spring.

The expression on Su Hao's face became more and more cold.

He took two steps back, distanced himself, and took a closer look at the zombie head hanging in the air.

Its face was covered in mud and pus, and its nose was rotten, revealing hard, blackened bony parts. The mouth is wide open, the teeth are neatly aligned, and it looks unusually hard.

In addition to the two very strange fleshy protrusions, its facial features are also significantly different from those of other zombies.

The eyes are large, and the white eyelids melt away like cream from the middle, revealing two clusters of lenses that are dark in color. It may be swelling or something else, but the eyeball seems to be much larger than it used to be. The hard bony orbit constrains this abnormal change, and the lens is squeezed from the inside out, desperately trying to find more space.

It feels like a boiled egg until it's half hard. It was gently pinched, and the force was not very large, just enough to pinch the egg, but it did not break through the limit of its toughness.

Su Hao slashed the zombie's upper lip with the tip of the knife.

This part of the muscle is tight, and there is no softness in the slightest as human lips should be. The knife sliced along the slightly sunken lip line in the middle, and the skin immediately split open to both sides of the incision, revealing two folded organs that were hidden directly above the teeth and extended from the gums. They are so small that they can be just covered by the upper lip.

Dong Guoping, who was standing next to him, immediately widened his eyes and unconsciously approached the front.

He had dissected both zombies, but he had not found the secret hidden beneath his mouth.

Dong Guoping watched Su Hao pick up one of the soft flesh with the tip of the knife, slowly fiddle with it, carefully pull the folded part apart, and the meat ball gradually turned into a strange organ more than 20 centimeters long, very soft, and tough.

It is tender, pink, and crystal translucent. The frontmost position forks from the middle, much like a scaled-down version of a crab pincer.

"What is this?"

Dong Guoping asked tremblingly. His tone was distinctly out of voice, hoarse with fear and shock.

Su Hao stared at this alien creature that obviously did not belong to any organ in the human body, and his gaze became colder and colder.

"It's mouthparts."

"Mouthparts?"

Dong Guoping subconsciously repeated this word, his eyes were blank.

"Look here————"

Su Hao shook the tip of his knife and pointed at one of the bulging pillars of flesh on the zombie's head: "Including the mouthparts in the mouth, these things are not normal organs that humans should have." I don't know if you've studied biology at a deeper level. But you should know that when there is an abnormal change in the body of an organism, it means that the cells that make up it have evolved, or the mutation has caused some irreparable defect. ”

As he spoke, Su Hao cut off the pillar of flesh with the tip of a knife: "Look carefully here———— the bone inside is very soft, indicating that the degree of cell activation is extremely high." There are not many blood vessels here, but the nerve tissue is dense and well-developed. If the zombie is still alive, then these two things will continue to grow to an incredible length. ”

Although it was not explicitly stated, the meaning of Su Hao's words was obvious enough. Dong Guoping had almost guessed the secret, but he still found it unbelievable.

"It's the tentacles."

Su Hao's cold voice shattered the most difficult illusion he had worked so hard to maintain: "The eyes have also undergone abnormal changes. It can squeeze the eye socket or create a new compound eye outside the orbit. Coupled with the mutated mouthparts of the lips, it is no longer a zombie, but a new mutated creature. ”

The expression on Dong Guoping's face instantly became very exciting.

"New creatures aren't zombies, aren't zombies? So, what exactly is that? ”

Su Hao's gaze left the lifeless head in front of him, and turned to the dark red zombie nailed to the wall next to him.

"Zombies, like humans, are constantly evolving and finding ways to strengthen themselves. Since the outbreak of the virus, they have almost passed their initial juvenile stage. ”
