And a superb elixir can often be tens of thousands of times the effect of ordinary elixir, which is a rare treasure that is hard to find and has no price.

An ordinary family, if he can get a top-grade elixir, then this ordinary family can squeeze into the ranks of top families in just a few years.

It stands to reason that a pill is gone after eating, why can it have such magical power?

That's because the best elixir is not as simple as an ordinary elixir, but has its own elixir, and the so-called elixir refers to the unique soul produced after the elixir reaches a certain quality.

In other words, this pill already has a life of its own, and at this level of pill, no one will take it, and it will simply be a ruinous thing.

Generally, it is enshrined in the ancestral hall, strictly guarded, and there are many peripheral organs, and no one is allowed to approach.

Only the head of the family can enter, and he has to bathe and change his clothes before each visit, and he needs to burn incense and bow down to enter the ancestral hall.

Because only by respecting Dan Ling and gaining the approval of Dan Ling, it will teach Dan Jue, and the effect of Dan Jue is hundreds of times better than taking Dan Medicine, taking Dan Medicine is a one-time thing, but Dan Jue is growing in the body in the way of cultivation.

The more people who cultivate, the Dan Spirit will also grow, and eventually it will turn into a spirit beast, the pill is different, the spirit beast incarnated will be different, maybe it's just a bird, it may be a tiger, or even the legendary unicorn, the phoenix is not unavoidable.

This kind of spirit beast is extremely aware of the master, once the spirit is opened, after identifying the master, it will never betray, and sincerely protect the master for the rest of his life, if one day the master dies unexpectedly, it will also go with it, and disappear from then on.

Therefore, when the spirit beast recognizes the master, there is a spirit beast to guard the family, and the family can not only stand, but also have the opportunity to make the children of the family who have cultivation talent become immortals under the cultivation of the spirit beast.

Although the allure of the best elixir is extremely high, there are still very few families that can have it, after all, this is not something that can be bought with money, and it still needs great chance.

Because its refining process is too complicated, the raw materials required must be two kinds of finished pills, the fire and the pill furnace are very harsh, and the person refining must also be a person with a high cultivation realm.

Therefore, for so many years, the best elixir has been extremely rare in the world, so rare that some families do not hesitate to use vicious methods to refine the best elixir.

The reason why this method of refining the elixir by using the body of the extreme yin and yang is poisonous is because, in the process of alchemy, the three souls and seven spirits in the human body are forcibly separated from the most essence of one soul and three spirits, and integrated into the elixir.

Therefore, this way of alchemy, either the fusion fails, and once it succeeds, it is the best elixir that has the Dan Ling.

And people who have lost one soul and three souls are no different from normal people in a short period of time, and they are even more intelligent and robust, which will give people the illusion that they have fully recovered.

However, within a year, he suddenly fell ill, fell into a coma, became a vegetative state, and finally could not escape the fate of death.

When I heard Number 2 talk about Yifan's symptoms and mention cultivation, many more hidden memories of this ancient family suddenly came to my mind.

I finally understood the ins and outs, it turned out that the body of the mosquito was not an antidote, but one of the pills for refining the best elixir, if it was an ordinary person, if it was poisoned, it would be eaten by the Gu worm that ate the body of the mosquito and died.

However, if the body of the extreme yin and yang is poisoned, and it happens to get the body of a mosquito, if it is eaten as an antidote, it will merge itself in the body, and quietly transmit some kind of signal to this ancient family, and when the people of the ancient family receive the signal, they will immediately send someone in person.

Secretly kidnap this person, quietly bring it back to the family, and the master of the family will come forward to personally refine the best elixir, once the refining is successful, then the family's wish to dominate the world can be realized as soon as possible.

If it weren't for the extreme yin and yang body eating the mosquito body as an antidote, the two pills in the body would still fuse on their own, and they would also secretly send signals to the ancient family, but because they couldn't refine the best pill, the ancient family would send someone to stay nearby.

After the effect of the drug is fully applied, this ordinary person's body will become a demon who has lost his mind after a night of transformation, and the next morning, the people of the ancient family who are guarding the vicinity, using some secret techniques, can control this powerful body to do some terrorist activities such as assassination.

Thinking of this, I suddenly remembered that Fauber had said that he felt a crisis lurking nearby, could it be that he was sent by an ancient family?

But according to the time calculation, Yifan had not taken the antidote at that time, so it should not be possible to transmit the information to the ancient family?

Unless...... They knew the outcome in advance, and suddenly, I thought of a possibility, just when I was about to ask the 2nd next to me to immediately strengthen the security of the apartment, 2 suddenly changed his face and said to me:

"Not good! Our apartment was surrounded by unidentified creatures......"

"Unidentified creatures? What kind of creatures can be invisible? I glanced at the window and didn't see anything, so I asked again at Number 2.

"They are not invisible, but they are too small, small enough to directly penetrate the walls and glass of this apartment, but fortunately the apartment is protected by a layer of invisible light film, even nano-sized particles cannot enter, so these unknown creatures are blocked." Number 2 said as she manipulated the small screen on her wrist.

"That is, these creatures are nanoscale?" I asked, surprised.

"It's micron-level, about one to five microns, equivalent to the size of between one thousand and five thousand nanometers, I asked No. 9 to catch more than a hundred of them, you can see it by looking at it." Number 2 called up the virtual screen again, pointed to a small transparent container on the screen, and said.

When I looked at the transparent container on the screen, the screen kept zooming in, and soon the transparent container was zooming in beyond the picture, but there was still nothing to see inside.

It can be seen that this creature is really small, so small that it takes a microscope to see it clearly.

After about a dozen seconds, some small red dots appeared on the screen, and as the dots got bigger and bigger, I finally got a good idea of what the microbes looked like, and they looked like a small bird.

When the picture finally froze on one of the creatures, it dawned on me, looking at the largest creature photo zoomed in on the screen, wasn't it a lifelike swift about to spread its wings?

"When we first discovered that there were unknown creatures trying to attack the protective light film of the apartment, the location happened to be in the bedroom window of the purple swift, probably because of the blocking of the light film, so these creatures gradually surrounded the entire apartment, obviously their original purpose was just to enter the room of the purple swift, do you need to let them in?" Number 2 looked at me and asked.

"If you put in a small batch, can you guarantee that you will kill them before they hurt the people inside?" I asked, pointing to the picture of the swift on the screen.

"I'm completely sure that it's less than a thousand." Number 2 replied in the affirmative.

"Then open the light film at my window, put in a thousand, close the light film immediately, and observe what happens." I said decisively.

"Okay, you put on these glasses and you can see these creatures, for safety, please take a few steps back, and when I'm sure it's safe, you can come back."

After 2 finished speaking, she handed me a pair of glasses that looked very delicate, and after seeing me take three steps back, she took two more steps forward, completely blocking directly in front of me, and then quickly made a few quick movements on the small screen on her wrist, and quickly raised her head and stared cautiously at my window, while aiming the gun in her hand at the window.

The moment I put on my glasses, I felt that everything in front of me became extremely clear, almost spotless, and at first I didn't feel much different, but when I stared at the window, I could clearly see a pale green film of light, shaking slightly outside the window.

Apparently this is the light film that protects this apartment, and the light film is slightly shaking, and from time to time there is a halo similar to ripples, and I take a closer look, it is the reason why those little swifts are constantly hitting the light film.

Then, I saw a crack in the light film, and countless swifts poured in, and after about six or seven seconds, they quickly closed again.

When the swifts came in, they did not wander around, but began to gather together, and soon coalesced into a feather, a purple feather, to be exact.

No. 2 raised his hand, gently caught the feathers falling from the air, looked at them carefully for a while, and after confirming that there was no danger, he turned around and walked up to me and handed the feathers to me.

I gently pinched the root of the feather with my fingertips, and after studying it for a long time, it was just a piece of swift feathers, and there was nothing special about it.

So, I nodded, glanced at the dense swifts outside the window, and motioned for a batch to come in.

No. 2 was a little cautious at first, only letting in a thousand, this time a feather again.

After that, after putting in thousands of them in a row, the formation is not a feather, some are like a piece of intestines, some are like a piece of bone, and some are like the pupils of an eye.

When I had these feathers and bits and pieces of body parts in the palm of my hand, I probably guessed what this dense little swift outside the window was.

"Let them all in, there should be no danger to us." I said with confidence.

"Okay." Number 2 replied without any objections.

As the light film opened completely, all the swifts outside poured into my room, and I held my hands high, and in my palms were feathers and body parts that had been collected earlier.

After that, a magical scene happened, I saw the feathers and parts in my palm automatically float into the air, floating there quietly, and the swifts that poured in from outside kept flying towards them, and began to merge with the feathers and parts floating in the air.

Over time, more feathers are formed, more body parts appear, and finally, when the last micron-sized swifts fly into the light film, Number 2 quickly closes the light film.

I saw a palm-sized swift gradually forming in front of me, and as I expected, those micron-sized swifts were completely fused together to become a real swift.

In the moment of complete merging, the swift awoke, suddenly opened its eyes, screamed happily, and flew around me and 2, as if looking at the two of us.

Flying and flying, and tilting his head as if thinking about something.

When I saw this swift flying in front of me, a vague memory came to my mind.
