Ling Yifan was about to arrest the guy who was doing good deeds, but suddenly thought about it, this would be easy to expose, and it would not be appropriate to kill him if he finished investigating. Although these outer sects are not important, they may have their talismans in the main city, and if they die, I am afraid that the main city will know it as soon as possible, and it is impossible for such a large force to have no management means.

Thinking of this, Ling Yifan's heart moved, a smile appeared on the corner of his mouth, and he said secretly: "Then the "Dan Dao Miscellaneous" is afraid that it will come in handy this time, but it seems that these alchemy materials will have to trouble you, I'm afraid that you can complete the task three times." ”

Thinking of this, Ling Yifan's divine sense moved, and he carefully searched for these twenty-seven outer sects, and this comprehension of the law to obtain the soul seed is really good, and he can't help but have strong soul power, and he generally doesn't have to worry about being discovered.

After searching carefully for a while, Ling Yifan's spirit was shocked, and he found it, and then his body moved, and he swept towards the ghost of the sect in front of him. "This invisibility cloak is very convenient for doing this trick!" Ling Yifan teased secretly in his heart.

With Ling Yifan's current soul realm and cultivation, coupled with the effect of the invisibility cloak, it is still easy to enter this outer sect with the highest cultivation of only the third order of Yuanying, I dare not say that it is like entering the realm of no one, but it is not much worse.

Not long after, Ling Yifan silently entered an underground secret room of this outer sect according to the location sensed by his divine sense. This secret room and its secrets are unguarded, it seems that only the guy who is turning the phoenix upside down knows about it, which saves Ling Yifan a lot of trouble. I walked along the dark secret passage for a long time before I came to a stone door.

Behind this stone gate was the secret room full of spirit grass that Ling Yifan's divine sense found, but Ling Yifan's divine sense swept through the stone door, his brows furrowed slightly. There was a prohibition on this stone gate, and if he hadn't made it a great achievement, it would have been difficult to find the prohibition left on it.

However, this prohibition was not a threat in Ling Yifan's eyes, and he could be defeated with a casual blow. It's just that in this way, the changes that happened in this secret room will be perceived by that person, and this is not the result that Ling Yifan wants.

Fortunately, after Ling Yifan's identification, this prohibition was only a first-level prohibition, and it was only used as a warning, and Ling Yifan broke it after a little waste.

When I opened the stone door and entered it, I saw a stone room of more than ten zhang in size filled with all kinds of spiritual grass. Ling Yifan also found a Dan furnace in a corner. Ling Yifan checked it, it was only primary, but it was enough for himself.

Ling Yifan unceremoniously packed up and took it away, and after leaving the secret room, Ling Yifan found a mountain range that was relatively close to the mountain gate and opened a cave, so that it was more convenient to monitor the movements of the outer sect.

Ling Yifan is preparing for a long-term battle this time, so the opening up of this cave mansion is also more elaborate than those temporary ones in the past. This cave house is a living bedroom, a storage room. The room used to study alchemy, as well as stone tables and chairs, were all available, which showed how determined Ling Yifan was, and he would never stop if he didn't slap this Xuanming Sect hard.

Ling Yifan looked at the opened cave mansion and was satisfied, but there was something missing, that is, the formation of the hidden cave mansion, and the only set of formation flags with hidden aura was given to Ziyun.

Ling Yifan shook his head, and now he could only cover this place with his divine sense. With Ling Yifan's current first-level forbidden realm, he could barely refine a set of heaven-level inferior array flags. It's just that this time is afraid that it will take a long time. What Ling Yifan lacks most now is time.

Fortunately, it was not very soul-consuming to divide a part of the divine consciousness to cover this cave, and once it was ready, Ling Yifan took out the "Dan Dao Miscellaneous Chapters" in exchange and studied it, which listed no less than a hundred kinds of pills and potions with strange abilities.

Ling Yifan screened it, and first chose a formula called 'Tilting Heart' to study it, as the name suggests. This thing is known to be endless, so it is called 'pouring heart', and the time limit is half an hour.

For the refining of this elixir, the minimum requirement for refining under the three grades must be Yuan Ying cultivation, and the minimum Dan furnace for refining is the primary Dan furnace. The four qualities require the cultivation of sanctification. Intermediate Dan Furnace, Ling Yifan didn't plan to study it at the moment, just the most basic one was enough for him to study for a while.

Ling Yifan took out the Dan furnace, the structure of this Dan furnace has two layers, inside and outside, and the middle is a mezzanine, which produces flames.

This Dan furnace must be blessed by the formation, there are holes in it, and the Yuan Force will be injected into its hole, and the Yuan Force will be converted through the formation to produce flames in the middle of the interlayer. Then the required materials are put into the Dan furnace according to the requirements, and the heat can be controlled, so that the Dan can be refined.

A total of eighteen kinds of medicinal materials are needed to refine this 'Pour Heart Scatter', and Ling Yifan rummaged through them according to the requirements on them, but there was no shortage of them, and they all had them. The first time he studied this elixir, and it was also a forbidden medicine in the alchemy world, Ling Yifan was a little ridiculous when he thought of this.

According to the requirements, the Yuan Force in Ling Yifan's body flowed out through the guò fire element and injected into the Dan furnace in front of him. Ling Yifan's divine sense cautiously sensed the changes in the Dan Furnace, and suddenly found that the moment it was injected with Yuan Force, a flame appeared in the mezzanine of the Dan Furnace.

Ling Yifan was overjoyed in his heart, and suddenly the Yuan Force of his left hand was activated, and the Guò Wood Element was cast, and the Yuan Force that was cast was injected into a hole on the left. The flame burning in the Dan furnace suddenly became much stronger, "No wonder the fire wood attribute is the best qualification for refining the pill, wood makes fire, so that you can consume the least amount of yuan power to exert the best flame temperature, this is still my wood element is only one percent, if there are more, the power of this flame is even better." Ling Yifan said secretly in his heart.

Having a preliminary understanding of this alchemy technique, according to the order, Ling Yifan put each spirit grass into the Dan furnace according to a certain proportion, and carefully controlled the temperature of the flame.

Because it was the first time, the operation was very jerky, and finally when the thirteenth spirit grass was put into it, the temperature of the flame showed a slight deviation, and with a 'snort', the spirit grass in the Dan furnace that had turned into liquid suddenly turned into flying ash and failed.

Ling Yifan's eyes widened, and he scolded secretly in his heart, "This can't be done?" It seems that this alchemy is not only an individual life, but also a meticulous work, no wonder the pill is so expensive, and the temperature difference between this flame and the slightest bit can't be." ”

With the experience of the first failure, Ling Yifan became more careful this time, his divine sense focused on perceiving the temperature of the flames, and his soul power carefully controlled the injection of Yuan power.

Although he was very careful this time, he still failed, but because Ling Yifan obtained the soul seed, so, the cultivation of the ninth order of the Yuan Infant plus the soul realm in the later stage of the soul seed, Ling Yifan quickly mastered the refining technique after failing several times in a row.

In less than a day, Ling Yifan succeeded in refining, Ling Yifan's progress speed was not even unimaginable for those cultivators of the same level. Which one didn't succeed after failing countless times and consuming countless spirit grasses? But there was no way, Ling Yifan was a ninth-order Yuanying cultivator who had comprehended the law.

Ling Yifan devoted himself to refining for half a month, and screened a total of more than a dozen pills that he felt useful. Half a month of refining, not only did he successfully refine the required pills, but at the same time, the success rate of refining pills below the third grade was also extremely high, but Ling Yifan estimated that it would not be so easy after the fourth grade.

Now this primary elixir can be refined so smoothly, all of them rely on themselves to obtain the soul realm of the soul seed. In the past half a month, Ling Yifan had obviously felt that his soul power had also increased slightly, which could be regarded as an unexpected gain.

In addition to cultivation, this soul power increase will be enhanced when studying things related to the soul, such as the Forbidden Dao, the Dan Dao, and refining weapons.

After Ling Yifan finished refining the elixir he needed, he was in a happy mood, and put the important things into the space ring, he didn't want to come back and find that this place had been robbed, without the cover of his divine sense, this place was easy to be discovered.

After Ling Yifan cleaned up, he said to himself with a smile: "I hope it won't disturb you this time!"

Immediately, Ling Yifan put on an invisibility cloak, concealed his body aura, and shot towards the mountain gate of the twenty-seven sects.

A moment later, Ling Yifan's illusory figure appeared outside the mountain gate of the Twenty-Seven Sects, his divine sense swept away, and he secretly sighed in his heart. Fortunately, this guy is still in the sect, but looking at his posture of sleeping soundly on the third pole of the day, I am afraid that he fought a lot last night.

Thinking of this, Ling Yifan secretly cursed in his heart, "When did my thoughts become so complicated." Then he comforted in his heart: "Don't blame me, this guy is not a good bird himself, and whoever sees him will not think of anything good." ”

I saw Ling Yifan shake his head, his body moved, and flew silently towards the man who was sleeping, pitiful A wonderful morning with a good dream was about to turn into a nightmare of his life... (To be continued......)
