"The swallow is a symbol of spring and recovery, and the swallow potion made by our witchers can speed up the recovery of body injuries."

"If you're facing a protracted battle, drinking a bottle of Swallow Potion early can help you recover most of your normal injuries quickly."

"Even if you're seriously injured, it can help you stabilize your injuries and prevent them from getting worse."

Geralt explained to Wayne the effect of the swallow potion as he took out a handful of celandine petals, weighed them with a weighing tool, put them in a container, and crushed them into a white and transparent juice.

Then he used a spoon to scrape off a layer of sour-smelling bodily fluids from a water ghost brain and threw it into a container.

Finally, he took out a bottle of dwarven spirits from his waist, poured half a bottle into the container, placed it on the stand of the fire, stirred it too, and continued to say to Wayne:

"The recipe of the swallow potion is relatively simple, only the petals of celandine and a part of the water ghost brain, the weight ratio is two to one, add the spirit and boil for an hour, and you can do it."

"It is one of the most commonly used potions of our witchers, suitable for most battles, has no side effects of its own, and is also effective in counteracting the side effects of several potions like Thunder, Maribo Forest, Triple Crown, Stan Morford's Elixir, and so on."

"It tastes like rotten oranges with lard."

"Of course, just like our other witcher potions, swallow potions also contain a certain amount of toxicity, and only we witchers can use them."

"Ordinary people can also have a certain recovery effect if they drink it, but before that, they will be poisoned to death."

Wayne listened and took notes, watching the mixed liquid in the container, which slowly turned from white to pale yellow under the high temperature of the flame, and an unpleasant smell filled the air.

Swallow Potion is indeed one of the most famous of the witcher potions, and it is often seen in both novels and games, and even in the Witcher III game, Geralt also relied on Swallow Potion to save an ordinary woman who was seriously injured.

The two sat by the cold lake and waited for an hour, during which Geralt taught Wayne how to boil potions, how to use the tools of the potions, and some other potion recipes, and let Wayne handle the celandine petals and water ghost brains himself.

In the end, after consuming six water ghost brains, a small bag of celandine petals, and three bottles of spirits, they refined a total of twelve bottles of swallow elixir.

Geralt took four bottles and stuffed them into his pocket, then motioned for Wayne to take the remaining eight.

Wayne was not polite, he packed the rest of the swallow potion, he took out one of the bottles, looked at the pale yellow transparent liquid inside, and asked with some curiosity:

"Geralt, how long can this potion be stored?"

"I read that different potions have different poisons, and we witchers can't take these poisons indefinitely."

"The average witcher will reach his limit by taking two or three bottles of potions at the same time."

"Are there any specific criteria for this?"

Hearing this, the white wolf looked up at the time, then got up and began to pack up the alchemy tools on the ground, saying:

"Indeed, although the Demon Hunter Elixir is powerful, if we drink too much at the same time, not only will it not be beneficial, but it will also cause serious damage to our body."

"As for how many potions you can drink at the same time, it depends on how much toxicity the mutant organ in your body can bear."

"It's the same amount of alcohol as it is."

"The stronger the body, the better the physique, and the higher the toxicity that a demon hunter who regularly takes various potions can withstand."

"However, because our potions are made with spirits, they don't spoil easily, and they can be stored for a fair amount of time."

"It can be stored for about half a year."

Wayne nodded, this was more in line with his understanding, since the degree of toxicity of each demon hunter was related to their mutated organs, so could it be considered that taking these highly poisonous potions could temper their toxicity resistance to a certain extent?

Looking at the swallow potion in his hand, Wayne suddenly thought of the mutation level in his skill column.

In the past year and a half, he has tried many methods, but he still has not gained any proficiency in the mutation level.

Perhaps, the witcher potion in his hand is a way to exercise the mutation level.

Wayne thought for a few seconds, then turned to Geralt and said:

"I haven't taken a witcher potion yet, and I'd like to try the effects of the swallow potion."

Geralt shrugged indifferently, not surprised by the young man's curiosity.

Still, he reminded:

"Our potions are made from spirits, so if you don't drink enough, it's best not to drink too much."

When Wayne heard this, he nodded indifferently, in his previous life, he was a fierce man with a plate of peanuts and a few catties of high-grade liquor, how could he be afraid of ancient spirits?

He first used a clean knife to cut a shallow wound on his wrist, then picked up the swallow potion, endured the sour smell, and smothered it in one gulp.

As the yellowish liquid entered his body from his throat, a burning heat, mixed with a slight splitting pain, began to burn in his internal organs.

Soon, however, the pain and burning sensation began to spread throughout his body, and slowly disappeared, and a warm feeling enveloped his whole body, and his body was no longer as uncomfortable as before.

Then, when the warm feeling flowed to his arm, Wayne could clearly feel that the shallow wound on his arm was no longer painful, but had a crisp itch when the wound healed.

At the same time, the system's prompt sounded as he expected.

Mutation proficiency +1, current progress: 1.

Mutant LV1: +10% mana regeneration speed, +1 anti-toxicity.

After hearing this hint, Wayne was overjoyed, compared to the swordsmanship level that takes several hours to improve a little proficiency, the mutation level is the same as the magic seal level, and it can be quickly improved by drinking medicine every day.

And the bonus brought by the mutation level is very helpful to improve his strength.

The faster the mana is restored, the more spells you can cast, and the faster you can level up the seals.

And the higher the poison resistance, the more witcher potions you can drink, and the faster you can increase the mutation level, which is simply a virtuous circle.

It seems that in the future, drinking potions will also become one of his daily activities.

Wayne thought so, and became even more interested in the alchemy Geralt taught.

I just don't know if his cooking skills can play a role in boiling potions, making these unpalatable potions delicious.

If that were the case, he wouldn't mind helping the other witchers of the Wolf School to brew potions.
