Twenty-nine days later......

"The Yin Pavilion appears once every fifteen days, every three Yin Pavilions, and the third Yin Pavilion appearance is called the Yin Tide."

Chen Fu picked up the pen, wrote compact handwriting on the paper, and then waved the pen to blacken it all.

As his meditation skills improved, his memory became more and more terrifying.

For him now, most of the things he will not forget as long as he looks at them once.

And what he had just written on the paper was the information he had obtained from his last trip to the Pavilion.

When he went to the Yin Pavilion this time, he finally changed into a full black dress with an unadorned iron mask.

The information he gathered seemed to be well known.

The third Yin Pavilion is called Yin Tide in the current life, and the Yin Pavilion will only appear one night on weekdays.

However, in the case of a yin tide, the Yin Pavilion will appear for two consecutive nights.

During the duration of the Yin Tide, the black fog of the Yin Pavilion will be more terrifying, but there will also be more and stronger exercises.

At that time, the earthly grade exercises will no longer be rare, and there will be a number of heavenly grade exercises.

As for what kind of exercises would appear in the deepest part of the Yin Pavilion, no one could have imagined it.

"After the phoenix fairy left, I was definitely not the only one who watched the secrets of the Yin Qi Pill."

Chen Fu looked at the box next to him, which contained a Yin Qi Pill.

Yin Qi Pills can be stored for up to three months, and after three months, they will be completely useless.

This is the last time he deliberately bought two, but only used one to hide.

After he bought this pill, he looked at it carefully, and he could see that this was definitely an extremely complete pill.

In other words, this Yin Qi Pill was definitely from the hands of a highly skilled alchemist.

By this time, he had completely determined that Ge Cizhou was the Phoenix Fairy.

After all, Ge Cizhou is the only one who is both a young woman and a skilled alchemist.

"Thinking about it this way, if you want to peek into the secrets of the Yin Qi Pill, you need to meet two conditions."

"First, that person's qualifications must be good enough to be qualified to discover the Yin Pavilion."

"Second, that person needs to work in the Dan Room, and he must have a certain knowledge of alchemy."

He estimated that there were only more than 50 people in the entire Gandao Palace who were qualified to enter the Yin Pavilion.

And there are only 60 people in the entire Dan Room, of which there are only 20 experienced alchemists.

However, there were nearly 4,000 disciples in the entire Gandao Palace.

The probability of satisfying both condition 1 and condition 2 is only 1 in 16,000.

"However, although the probability is small, it must be guarded against, after all, I am 1 in 16,000."

"And some people who enter the Danfang rely on hard work, but more people rely on talent."

"To a certain extent, this somewhat overlaps with the conditions for entering the Yin Pavilion."

"The best and worst plan is that there are at least three more people with the same conditions as me."

"In that case, I'll be more cautious tomorrow."

Chen Fu thought for a moment and took out a pair of monoculars from the package next to him.

This pair of monoculars that was ahead of his time was, of course, carefully polished by himself.

Although Chen Fu didn't know how to make steam engines and fertilizers, he still knew the simple optical principles.

However, in order to avoid the butterfly effect caused by the leakage of technology beyond the times, his monocular is only for his own use.

When this time passed, he was ready to destroy the monoculars to prevent future troubles.

"Beyond the millennium of time, I have the potential to become a saint, but I am more likely to become a demon."

In the martial arts world, it is completely unknown what the impact of technology beyond the times will be.

Chen Fu prepared not only telescopes for this operation, but also khaki robes.

He had chosen a hill far away from the back mountain, but where he could see the situation in the back mountain from a high vantage point.

The top of the hill is far enough away from the back mountain that you can't see what's going on in the distance unless you use a telescope.

And the earthy yellow color of the burqa can perfectly blend in with the whole mountain.

In addition, there is an unadorned matte iron surface to conceal one's identity.

As well as the use of medical knowledge to prepare both odor and insect repellent functions of the powder, enhance concealment.

The props are only part of it, and his other confidence comes from the Blue Dragon Seal Method, which he has practiced day and night.

He has preliminarily cultivated the Hidden Dragon Seal, which can reduce his presence in front of others.

"It can reduce my sense of existence, and it can help me escape when necessary."

In order to avoid bumping into other people, he had already gotten up in the middle of the night.

Then he quietly made his way to the hill he had chosen.

The distance between the top of the mountain and the back mountain is quite long, and no one would have imagined that someone would be able to ambush and observe the back mountain from here.

After Chen Fu smeared his body with masking powder, he slowly lay down in a hidden place on the mountain.

His breathing was slow and long, and he entered a state of low consumption.

The sun rose and set, and after ten hours he finally saw someone coming.

He immediately picked up the monoculars and fixed his gaze on the man.

The man wore a slender olecrasbill mask, and he could tell at a glance that he was a man.

"Sure enough, someone has the same idea as me and wants to spy on the secrets of the Yin Qi Pill." His scalp immediately went numb.

If he thought that the phoenix fairy was not there, he would secretly go to the back mountain at night.

Then after he bumps into the other party, a fierce conflict will definitely break out.

Chen Fu carefully observed the man and found that his figure was still somewhat familiar.

"I don't know which senior brother I've met." He said secretly in his heart.

After Chen Fu waited quietly for a while, the man finally made a new move.

After the man took out the small Dan furnace, he actually took out a knife and slowly cut his fingers, squeezing out the blood and dripping it into the Dan furnace.

As his blood slowly dripped down, something ominous began to appear around him.

Black creatures that swam like snakes appeared in the air.

But the head of the snake looks like a huge eyeball, and the kernel of the eye is a protruding and distorted face.

"This back mountain can't be used to seal something strange."

The back mountain is just a name for an area, and when you enter the back mountain, the soil turns black.

And the black soil does not give a sense of abundance, but is full of holes like carrion.

Therefore, Chen Fu often hears all kinds of weird rumors about the back mountain.

Two or three black snakes were attracted by the blood in the Dan furnace and burrowed into it.

However, more black snakes set their sights on the person dripping blood, and more and more gathered.

I don't know who started, and a dense black wave rushed towards the man.

The man didn't seem to expect so many black snakes to appear, his body stiffened, and then he hurriedly closed the Dan furnace and began to fly.

The speed at which his body exploded was extremely fast, as if it was falling by the wind, and he flew out of a hundred meters almost instantly.

However, Chen Fu saw that he was still almost caught by the black snake, and when he came out, several pieces of flesh with round incisions were missing from his back.

A large amount of blood immediately stained his black robe with blood.

I'm afraid it will take a few years to heal from such an injury.

"Hell, I kind of know why the Phoenix Fairy can monopolize it." Chen Fu muttered.

The difficulty of refining the Yin Qi Pill is not in the refining, but in obtaining the raw materials.

These monster black snakes that appeared inexplicably were obviously necessary materials for refining the Yin Qi Pill.

And if you want to lure out these black snakes, you must offer blood food and feed the tiger with your body.

After the man fled, the black snake finally slowly retreated, as if nothing had just happened.

Chen Fu slowly approached the back mountain, but only the dividing line that entered the back mountain.

However, just as he approached, he felt a feeling of suffocation, and suddenly a crisp sound came from his body.

Chen Fu put his hand into his arms, groped for a long time, and found that it was actually the Ningshen Ancient Jade in his arms that was broken in half.

"What does this mean? Ningshen Ancient Jade has the function of warding off evil spirits, but not much? He guessed.

If this is the function of the Tranquility Ancient Jade, to ward off evil spirits, then this function is too weak.

He looked ahead, and if he had taken a few steps further, he might have been in the range of the man who had been attacked before.

"While the conditions that trigger those things may be blood, taking risks isn't something I'm supposed to do."

Thinking of this, Chen Fu finally slowly retreated to a safe distance.

"Obtaining raw materials is so dangerous, even the Phoenix Fairy can't be completely unpaid."

"So there are two scenarios at the moment. Or, the backhill on weekdays is not so dangerous at all. ”

"Only when the Yin Pavilion appears or the Yin Tide appears, those monsters will be so active."

"Or, the phoenix fairy has mastered the method of deterring monsters, so that he can capture monsters without injury."

"Either way, it's beyond my reach at the moment."

"But it's a good thing to know that the Ningshen Ancient Jade has the function of warding off evil spirits."

"I just don't know if it's because of the blessing of the ancient jade, or because of the ancient jade itself."

Chen Fuyou returned to the courtyard without danger and began to look at the section of the Ningshen Ancient Jade.

The more he looked at it, the more he felt that the strange pale green of the Ning Shen Gu Jade seemed to have been seen somewhere.

He only thought about it for a moment, and suddenly found the corresponding answer in his mind.

"Isn't this kind of jade used on the statue of the god enshrined in the Heart Cultivation Temple?"

Chen Fu remembered that when he was still a handyman, he cleaned the Heart Cultivation Palace.

The floating jade belt on the statue of the god is made of the same material as the ancient jade of Ningshen.

In general, however, such inconsequential memories are not remembered even if they remain in his mind.

But now that he has the ability to improve his memory, he can recall most of the things he has seen.

"Will there be any connection between the statues of gods and men enshrined in the Dao Palace and those monsters sealed in the back mountain?"

"Or is it that the material used to build the statue of the god itself has the function of warding off evil spirits and suppressing demons?"

"The establishment of the Gandao Palace, it seems that there are many unknown secrets."

"Could it be that this is the reason why the Phoenix Fairy was able to obtain raw materials without injury?"

Chen Fu's fingers tapped on the tabletop, and thoughts kept popping up in his head.

The tide will continue tomorrow for another day, and he still has a chance to try.

If what he thinks is true, then this path may not be impossible.
