As soon as the aura in the demon pill spread, it quickly transformed into a stream of pure mana, and after a few breaths, it turned into a trace of mana, slowly integrated into the dantian, and soon became a part of its own cultivation.

As the aura continued to be born, the size of the demon pill was also shrinking out of thin air.

Du Fan noticed that the sip of the pill water he drank had been lingering around the demon pill, neither making rash moves nor withdrawing, but as if he had a spirit, he was watching the demon pill's every move.

As the size of the demon pill decreased, the concentration of the aura emitted began to weaken significantly, especially when this demon pill turned into one percent of its original volume, the aura that continued to spread out was already very small.

This phenomenon is completely different from the elixir or even the elixir essential oil.

After a while, something similar to Sha Shuo appeared, these things could not be melted, like impurities, and they could no longer give birth to half a point of aura.

At this moment, the Hua Dan water, which was originally eyeing the demon pill, suddenly began to churn violently, followed by a roll, and in the blink of an eye, the demon pill residue was wrapped in it, and the two immediately devoured each other and dissolved each other, and there was a sound of "Zizi".

After a few breaths, the Hua Dan Water, along with the Demon Pill impurities in it, disappeared out of thin air at the same time.

"It seems that there is no problem with the Hua Dan water I refined, and the method of taking the demon pill should be completely correct. Observing this, Du Fan's heart was relieved, and then his expression straightened, and he began to look inward about his own cultivation.

As Du Fan expected, the pale yellow demon pill of this primary-level demon beast did not generate too much mana in his body, and he had expected this, so at this time, he did not show too much disappointment.

After a while, Du Fan's face suddenly changed greatly, and his heart was shocked, but he was only stunned for half a moment, and then he showed ecstasy.

After taking the Demon Pill, the mana in his body did not increase much, but the stability period of the sixth layer of the Qi Refining Period seemed to be pushed forward by an invisible big hand, and it had already caught up with his usual struggle on the stability period for more than half a month!

Raising cultivation is extremely difficult for other cultivators, but this matter is nothing at all when put here by Du Fan, but it is a stable period that is very easy for others, but it is a hard injury in Du Fan's cultivation.

This is determined by his own spiritual root qualifications, and it can't be solved by pills, and even the essential oil that he exclusively developed is many times purest, because these are two things that are not very related.

Therefore, how could this discovery not make him happy in his heart?

"Although I have inferred that the demon pill will have some effect on the shortening of the stability period, but this effect is too amazing, this is just a pale yellow demon pill......"

Du Fan took a deep breath, his excitement gradually calmed down, and he muttered to himself.

"If it's a medium-yellow demon pill, then its effect ......"

After half an hour, his eyes suddenly flashed, his arm moved, and a medium yellow demon pill instantly appeared in his hand, and he swallowed it into his stomach with a mouthful of pill water.

Half an hour later, when Du Fan's eyes opened, a faint look of disappointment flashed on his face, and he muttered:

"This medium yellow demon pill naturally produces a lot more mana than the light yellow demon pill, but in terms of shortening the stabilization period, there is not much difference between the two, could it be that all grades of demon pills have the same effect on the stabilization period?"

It didn't take long for Du Fan to figure out the joints, and after a little thought, he suddenly slapped the storage bag with his right hand, directly took out a large handful of light yellow demon pills, put them on the wooden bed in front of him, and then took one of them and put it in his mouth, and swallowed it with a mouthful of Hua Dan water.

......

Three days later, Du Fan finished his cultivation, and at this time he smiled and said in a low voice:

"Originally, it took at least half a year to get through the stable period, but now it only took three days, and now my cultivation has entered the early stage of the sixth layer of the Qi refining period. ”

"However, with the improvement of my own cultivation, my stability period has almost increased in multiples, if I am lucky enough to break through to the foundation building realm in the future, the stability period may reach for a long time, even if it is a few decades.

At that time, if the demon pill still has this utility, the stability period will still be the biggest problem in my cultivation.

Alas, forget it, the boat will naturally go straight to the bridge, why should I think about such a distant thing now, and increase my worries for myself? Besides, whether I can get to that point in the end is a matter of two words. ”

Du Fan sighed, took a small sip of ginseng qi essential oil, and continued to cultivate.

......

This time, Du Fan had been cultivating for two months, and then he opened his eyes and said to himself: "Now that we are not far from the middle stage of the sixth layer of the Qi Refining Period, I believe that in a week or two, we can truly enter this stage." ”

Ten days later, Du Fan quietly left the wooden house, the invisibility ring in his hand, and went straight to a barren mountain hundreds of miles away from the Langlin Valley.

According to his original plan, he wanted to cultivate to the peak of the sixth layer of the Qi refining period in one breath before he would give up, but helplessly, there was not much stock of ginseng qi essential oil left on his body at the moment, and he had to reformulate a batch for his cultivation.

The journey of more than 100 miles, with Du Fan's running speed, has been reached in half an hour.

As soon as he came to the foot of the mountain, his mind immediately dispersed with all his strength, and he carefully observed the situation within hundreds of zhang around him.

After he advanced to the sixth layer of the Qi Refining Stage, the strength of his divine consciousness increased a bit.

Now that the coverage of his divine thoughts has reached a distance of five hundred and fifty zhang, even among the monks in the early stage of foundation building, he is also a leader, at least not weaker than the Langlin Valley steward Ma Tang Master.

After half a pillar of incense, Du Fan found a natural cave, which is located in the middle of the cliffs, the surrounding terrain is steep, the location is very remote, and there are overgrown weeds at the entrance of the cave, which is generally not easy to find, and it is really an excellent hiding place.

From the outside, this cave is about two feet wide and high, Du Fan walked into it, and after a little inspection, he had already judged that this place was barren and lifeless, and even if someone had come, it was at least a hundred years ago.

Although this cave is not big, it is more than ten zhang deep, which is enough for Du Fan to plant a large number of spiritual herbs and make room for the preparation of ginseng qi essential oil.

He didn't waste a single moment, after checking that there was no problem in the cave, he immediately took out all kinds of commonly used spiritual herb seeds, sprinkled them one after another on the ground in the cave, and then carefully applied the special fertilizer.

Immediately, he took out all the three sets of experimental equipment, used the spiritual herbs in his hand, and began to prepare ginseng qi essential oil at the same time.

After the cultivation of spiritual herbs, there was no need to manage too much, so in the next few days, Du Fan's main job was to manipulate the experimental equipment to prepare ginseng qi essential oil, and occasionally spare some time to spend in cultivation.

It wasn't until midnight on the twentieth day that Du Fan stopped his movements, and with a flick of his arm, he instantly put the three bottles of ginseng qi essential oil that had been prepared into the storage bag in an instant.

Immediately after, with a wave of his big sleeves, he put away the three sets of experimental equipment and the many spiritual herbs on the ground.

During this period, the amount of ginseng qi essential oil he had prepared was enough for him to use after the seventh layer of the qi refining period, and there would eventually be a surplus, so in a short period of time, he didn't need to worry about the matter of the elixir essential oil.

Walking out of the hole, after Du Fan's body moved a few times, he stood on the top of a cliff, stopped and looked into the distance, a cold wind hit, blowing his clothes and messing up his long hair.

At this moment, the night is as cool as water, the cold moon is like a hook, Du Fan is independent on the top of the mountain, feeling the late autumn Xiao Xiao, the cold is faint, and there is a sense of pathos and desolation.

After a long time, Du Fan's expression suddenly moved, he turned around slowly, his eyes fell coldly on a pitch-black boulder the size of a door panel dozens of zhang away, and said in a deep voice: "Who is Your Excellency, why did you appear here?"

"Huh?"

At the boulder that Du Fan was staring at, there was a sudden sigh, as if the other party could find himself, which surprised this person, but his voice was a little weird, and he couldn't tell whether it was a man or a woman, old or young.

"Du Daoyou is a good skill, no wonder someone is so jealous that he wants to kill you and then hurry up. The voice from before came out again, and the words were cold, as if they had no emotion.

Du Fan was stunned for a moment when he heard this, then his face was gloomy, and he said coldly: "Listen to Your Excellency, the purpose of your trip is to come specifically for Zaixia, we have never met, why do you recognize Zaixia, and how did you find Du?"

After Du Fan asked a series of questions, the other party did not come out with any sound, and obviously did not mean to continue to speak.

But what made the corner of his eyes jump was that the pitch-black stone, which seemed to be motionless, suddenly began to twist and deform, and produced a circle of circular ripples that could not be counted.
