"The medicinal properties of the three materials have been mastered, one main drug plays a leading role, and the effect of the two excipients is mainly to enhance and harmonize."

Cheng Shen put down the bottle of potion in his hand.

Once refining, he directly blended a bottle of excellent quality miniature life potion, but as he expected, this formula was of extremely low value to professionals, and the amount of excellent quality potion recovery was only 110 points.

However, the reason for emphasizing is that it is of low value to professionals.

This is because this potion can still have a significant effect on unawakened ordinary units.

The upper limit of an ordinary person's life is no more than one or two hundred points.

This bottle of potion.

It can already be called a life-saving elixir for the flesh and bones of the living and the dead.

Professionals, because their flesh and blood have begun to give birth to transcendent factors, whether it is healing or regeneration, it needs to consume more life activity.

But this consumption also means a greater burden on the professional.

The role of life medicine is to replenish the human body with additional life activity.

However, while replenishing the vitality of the drug, it is also necessary to pay attention to the other medicinal properties attached to the drug.

Most of the time, these medicinal properties are harmful to the human body and not beneficial.

With continued use, people can develop drug resistance.

Or even poisoning.

Drug resistance will reduce the effectiveness of all subsequent medications.

Therefore, it doesn't matter to the number of potions that are always available to professionals, and even if you bring a backpack of potions, only the first few bottles can be used.

What matters is the efficacy of a single agent.

This kind of miniature life elixir is basically only used by ordinary people and novices who have just changed jobs, like Cheng Shen, not only can it not provide much recovery after use, but it will also deposit poison in his body, affecting his overall state.

Naturally, the value is not much higher.

"Using Viper Ichor instead of the main potion in the recipe, Blood Herb, should enhance this recipe, but if you want to completely improve it, you need to upgrade all the ingredients to the next level."

Cheng Shen pondered.

He has already started to operate in his hands.

Step 1.

Extract the viper's liquid first.

The viper spirit fluid is stripped of the active and toxic components of the viper.

The horizon of energy unfolds.

The viper liquid in the vessel suddenly took on two colors, dark green and emerald green, which was also mixed with a large amount of gray substance.

Cheng Shen separated the three components one by one.

Soon.

He was given a pure life fluid and a venom rich in poison.

and a copy of the base material that he is currently unable to parse.

The basic matter, also known as the primordial matter, is an important part of the whole world, and the evolution of all objects is composed of different arrangements of the basic matter, but his ability cannot support him to analyze the primordial matter for the time being.

Cheng Shen threw aside the material of the Gray Lake Lake.

Then.

Look at the attributes of the two spiritual liquids in his hand.

A single pure life potion, taking a standard unit of flask dose, can bring 50 health regeneration per second for 10 seconds.

Apparently.

After stripping away the toxic ingredients, its recovery effect becomes stronger.

Cheng Shen immediately used a dropper bottle to extract a certain dose of the life spirit liquid in the vessel, and then poured the essence ingredients of the other two auxiliary medicines in the formula of the life elixir, yellow laurel leaf and orchid grass, into the crucible for mixing.

But maybe it's because the medicinal properties of the Life Spirit Liquid completely crush the other two ordinary herbs.

Ultimately.

It was indeed a successful fusion.

However, the effect of the finished product was not only not enhanced, but due to the incorporation of the medicinal properties of the two excipients, the recovery effect became worse.

"Failed attempt."

Cheng Shen casually threw the finished medicine aside.

He understood what the problem was, so he quickly came up with a solution,—— diluting the life fluid.

The Life Ichor is a fine-grade material.

The energy contained in it is much stronger than that of ordinary grade yellow laurel leaves and blue grass.

As a result, the properties of the medicine cannot be combined.

Then just dilute the energy level of the Life Spirit Liquid to the ordinary level.

Subsequently, Cheng Shen diluted a portion of the life spirit liquid in a ratio of one to three.

Mix again with the essence ingredients of the two excipients.

"Ding!"

Accompanied by a pleasant prompt.

Inside the crucible.

The liquid mixed with the three ingredients gradually blooms a vivid emerald green color.

[Refining successful!] 】

[Hint: You've created a new flask recipe that you can name!] 】

[Hint: Potion Blending Mastery +5!] 】

……

Cheng Shen looked at its attributes.

【Inefficient Elixir】

【Items】

[Grade: Excellent]

[Description: After taking it, it can instantly restore 100 HP, and in the next 10 seconds, continue to receive 20 HP per second]

【Refining: Orange】

……

Instantaneously return to 100 points.

Lasts 200 points.

A total of 300 health regeneration.

The effect of this potion is not as good as a pure life elixir.

But you know.

This is the effect of being diluted by one-third by one part of the life elixir.

A standard resource unit of Viper Ichor can extract a Life Ichor that can meet the needs of 3 doses of standard Elixir units.

Other words.

One unit of Viper Ichor can make 9 bottles of this recovery potion!

Considering that most of the survivors' HP is around 1000 points now.

Potions of this kind are sufficient.

Just right.

Catch the dungeon opening craze.

If this potion can be produced in large quantities, it will definitely bring him a stable income.

Cheng Shen shared the recipe with the other five residents.

After repeated refining work, they have become official Potions apprentices.

It has a certain practical ability.

It's just right for them to refine this entry-level potion.

It can not only improve the proficiency of the skills, but also strive to become a full-fledged pharmacist as soon as possible.

It can also generate income for the territory.

Kill two birds with one stone.

Cheng Shen continued to devote himself to the research on the more efficient ratio of life spirit.

But before that.

He needed to master more and more advanced herbal properties.

Cheng Shen has no professional guidance, and there is no specialized research data to view.

Only the most stupid way to understand the medicinal properties of other materials can be used.

"Go and buy all the herbs on the market."

He commanded.

The materials were quickly delivered to the shops.

Cheng Shen picked up a herb casually.

After a little scrutiny, he opened his mouth and gnawed off the core of the flower at the top.

Chew repeatedly.

Followed by.

A visible blue-green color appeared on his face.

[Gain Status: Poisoned!] 】

-2，

-2，

-2，

……

With his extraordinary negative resistance, Cheng Shen completely ignored the toxicity of this poisonous weed, and devoured all its branches, leaves, and rhizomes in one bite.

After full digestion.

Information about this herb popped into his mind.

"Feasible!"

Cheng Shen's spirit was slightly perked, and then he immediately kept stuffing the herbs placed in front of him into his mouth one after another.

……

[Hint: You have consumed a total of 500 ingredients with different medicinal properties to obtain a poison-resistant body (elementary)!] 】

……

The system prompt interrupted Cheng Shen's numb and mechanical repetition.

Because the medicinal properties must be absorbed by flesh and blood, he can't shield his perception by transforming into a bright red form.

After devouring an unknown number of herbs.

His entire sense of taste was completely out of order, and he couldn't taste anything other than the spicy sensation.

People are numb.

Fortunately.

The effect was only temporary for him.

Not to mention the taste organs, even if the stomach is burned through, it is just a small problem that can be cured by changing forms.

Cheng Shen stuffed the last few herbs in front of him into his mouth in one go.

Then.

only to look at the prompt of the system.

This Poison Resistant Body is actually a rare innate ability, and the effect is: increase poison resistance, and increase the upper limit of drug resistance.

This means that he can use a few more bottles of potions than others.

Crucially, this talent can continue to be upgraded, and will be further enhanced as the number of different herbs he consumes increases.

It's still pretty good.

Crash......

With a strange wriggling of Cheng Shen's body, he had already switched between the two forms.

A cloud of jet-black herbal residue was expelled directly from his body by the way.

"You can refine more efficient potions."

Cheng Shen thought.

The medicinal properties of hundreds of herbs flashed through his heart in an instant.

Among them, there are dozens of materials that can replace yellow laurel leaves and bluegrass, but he has to choose not only high-grade materials, but also the common ones that can be purchased in large quantities by other survivors.

After screening, there are only three materials left.

Cheng Shen took out each of these three materials and tried to mix them with the life spirit liquid in different proportions.

Soon.

He was given a new and highly effective formula for life potion.

【High Potency Elixir】

【Items】

[Grade: Excellent]

[Description: Instantly restores 500 HP after use, and continues to gain 80 HP per second for the next 10 seconds]

【Refining: Orange】

……

The total recovery of 1300 points is already quite good, through the combination of three materials.

The effect of the Life Ichor was nearly tripled.

Though.

Quantitatively.

The cost performance of a bottle of high-efficiency elixir is far less than that of 9 bottles of low-efficiency elixir.

But because of the limitation of drug resistance, such a bottle of high-potency elixir, even if it is sold for ten times the price, someone will pay for it.

"Still not ...... enough"

Cheng Shen wanted a potion that could also help him, but just looking at the recovery amount of the high-efficiency elixir, it was far from the standard.

Just as he was about to purify the life spirit liquid.

Highly condensed.

When making more complex blends of rare potions to improve their quality.

Suddenly.

The doorbell rang outside his shop.

……

[Hint: There is a special unit in your store!] 】

……

A system prompt is sent at the same time.

Cheng Shen was stunned.

Although his shop is already open, he does not have an entry permit for survivors.

At this time, only the local units that can be randomly refreshed can enter.

He hurriedly packed up everything, tidied up the white doctor's robe that he had specially changed, and walked outside.

Just out the door.

Cheng Shen suddenly felt a pang in his heart, and within the scope of his mental induction, he sensed an energy reaction that made him extremely uncomfortable.

Dead

Cold.

Suddenly, an equally terrifying fluctuation in his heart was about to move!

It's a weird power!

His expression remained unchanged, and when he looked at the visitor, he saw that the man was dressed in a gray rag garment, and every part of his skin was tightly wrapped, leaving only a pair of bloodshot eyes exposed.

He was standing in a strange way.

Stand on your feet together.

Stand firmly in place in a posture that does not conform to the anatomy of the human body at all.

At first glance, I thought it was a giant gray-black crow.

"You, what do you want to buy?"

Cheng Shen was very vigilant.

What is tainted with the smell of weirdness is not necessarily the real weirdness.

It may be, like Aoki, who directly controls the strange alien existence, or it may be an unlucky egg who is contaminated by the same weirdness as him.

But either way.

All mean that the other party has an extremely high probability of spreading the curse!

"I ......"

A hoarse voice came from under the thick gauze wrapped around the other party, and at the same time, Cheng Shen smelled a pungent smell of disinfectant water.

The smell suppressed the rancid stench on the other party's body.

Quite pungent.

"I want ...... Life-prolonging elixir ......"

He said hoarsely.

Cheng Shen wanted to refuse and say that he didn't sell any potions here, so he drove him away.

But on second thought.

It doesn't matter if his attitude irritates this guy or not.

If he didn't take a breath and died here, the curse in his body would explode immediately.

Form a new spook!

Cheng Shen looked at the backpack and made sure that the state of the Spirit Removal Blade had not changed much, and it could still be used, and he was slightly fixed in his heart.

He took out the high-potency elixir he had just refined.

airspace,

Through a wisp of spiritual power, it is entrusted to the past.

"I only have this elixir here, I don't know if you can be satisfied."

He said.

The man stiffened his palm, and blood suddenly oozed from under the tightly wrapped gauze.

As if he didn't notice the pain, he didn't say a word, took the elixir in his hand, lowered his head and looked at it carefully.

"How much is ......"

It seemed that he was satisfied with the attributes of the high-potency elixir.

Cheng Shen barely squeezed out a smile, "No money, the new store opens with a big reward, you are the first guest to come, and the first order is free." ”

“……”

The man stared at Cheng Shen with a pair of red eyes and didn't speak.

Half a day.

It was as if he had suddenly regained his breath.

"Thank you......"

With that, he turned and walked away.

Cheng Shen looked at his movements with a high degree of nervousness, he always felt that this guy's appearance was very wrong, as for collecting money, don't be kidding, any item on this guy's body may carry a curse!

Even if it's gold!

Cheng Shen just wanted to be able to send him away safely, and everything would be fine.

He was ready to make a violent move, but whenever this person showed the slightest abnormality, he dared to directly pull out the soul slayer blade and pin him to the ground.

It's not a last resort.

Cheng Shen really didn't want to deal with any weird-related existence.

When!

At the moment when the other party walked out of the door, a pitch-black iron plaque suddenly fell from him.

Cheng Shen's heart tightened, and he immediately shouted: "Your thing has fallen!" ”

The other party didn't seem to hear it.

The back foot took the front foot and disappeared directly at the door, Cheng Shen rushed out, rolled up the iron card with his mental power, and chased out the door, but as soon as he came out of the door, the strange figure had disappeared without a trace.

"Was it intentional, or did it ......fall unintentionally?"

Cheng Shen stood in place, his eyes were a little scary.

He had a vague feeling that the person he had just now might have something to do with the Old City he was about to go to.

The other party will appear in most likely not a random accident.

It's intentionally arranged!

But whether this arrangement is the design of the system or is influenced by another factor.

I can't say for sure.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
