The old man who cultivated as an old man in the early stage of the Green Dan, said that the demon refining technique was the method of the Nine Star Sect, which was hinting at the importance of the demon refining technique to the Nine Star Sect, and once Chang Shan asked for the demon refining technique, it was relatively easy for him to refuse.

However, this old man didn't know that Chang Shan was not interested in refining demons at all, he was just interested in the demon refining array that could completely refine the spiritual power of a demon beast.

Demon refining is actually equivalent to a method of improving cultivation with unsuitable pills, of course, there are its subtleties, but its flaws are irreparable.

"Take this kind of exercise as the method of your Nine Star Sect's Zhen Sect, I'm afraid that your Nine Star Sect doesn't have a few cultivators in the Qingdan stage!"

The old man didn't know if Chang Shan was testing the reality of the Nine Star Sect when he said this, so he was slightly stunned for a moment, and let out a long sigh, as if to indicate that their Nine Star Sect did not have few cultivators in the Qingdan stage.

In fact, the Nine Star Sect, a sect that was basically not ranked in the Yellow Heavenly Emperor Dynasty, even if there were Qingdan Stage cultivators in the sect, there were only two or three extremely weak ones at most.

The old man hinted that there were Qingdan stage cultivators in the Nine Star Sect, and he couldn't scare Chang Shan, who was about to advance to the Zidan stage, at all.

Chang Shan's strength is unimaginable to the old man, however, he has his own principles of life, for the enemy, he can do things to destroy the clan, and for irrelevant people, even if the other party's strength is weak, he will not do anything to rob the other party.

"Gao Mou passed on your method that can make up for the shortcomings of the Demon Refining Technique to a certain extent, and you gave Gao Mou your Demon Refining Array to observe for two months. ”

The old man was stunned for a moment, looked at Chang Shan and said, "Senior is a formation cultivator?"

"Hmm!"

The old man hesitated for a while, then turned to the nine Nine Star Sect disciples who had just set up the formation with him, and said in a deep voice, "Take out your demon refining beads!"

The faces of all the Nine Star Sect disciples were a little ugly, and after a while, the nine Nine Star Sect disciples who had just advanced to the late stage of Lan Dan took out their demon refining beads.

Nine demon refining beads, plus one Burning God Bead, formed a demon refining array.

Chang Shan took the ten beads handed over by the old man, observed them, took out a jade slip, entered the "Yantian Jue" into it, swept around the faces of the disciples of the Nine Star Sect, and said with a faint smile: "On other days, if you take a fancy to the things of the small forces within the sphere of influence of your Nine Star Sect, I wonder if you will exchange something of equal value with Gao Mou?"

After saying this, Chang Shan threw the jade slip in his hand towards the old man, and without looking at the old man's somewhat embarrassed face, he sat cross-legged on the ground, laid down the demon refining array, and comprehended the mystery of the demon refining array.

Chang Shan has only been enlightened for seven days, and he has basically understood the subtleties of the demon refining array.

When he first saw the Demon Refining Array, the reason why Chang Shan saw through the subtleties of the Demon Refining Array was because the Demon Refining Array was actually a relatively special Dan Array.

The general Dan array is to absorb the spiritual power of the Quartet and return to the center and turn into a mixed element, which contains the mystery of the Dan Dao.

The demon refining array was to scatter the spiritual power and the surroundings, and then, the mixed yuan pill was formed around it, and this process was like splitting a refined pill into nine pills with less medicinal power.

"The alchemist pursues a pill with stronger potency and comparable medicinal power, and this strange pill array that turns one into nine was created by that pill master? Did he create this pill array because he got an elixir that he couldn't refine? If so, he should have created this pill array to weaken the effect of the pill, why didn't the demon refining array have such an effect? Is it because the ancestor of the Nine Star Sect didn't get the complete Dan array, or did the Dan Xiu who created the Dan array not understand this Dan array at all?"

Chang Shan pondered for a while, and then continued to deduce the demon refining array.

Extrapolating the formation diagram of the demon refining array, Chang Shan carefully observed the mysteries of the entire demon refining array, put away the demon refining array, handed the demon refining array to the old man in the early stage of the Green Pill, and asked in a deep voice, "Are you Nine Star Sect proficient in the Dan Dao?"

The old man was slightly stunned and replied, "There are Dan masters in the Nine Star Sect, but they are not alchemy sects. ”

"So, this demon refining array shouldn't have been created by your Nine Star Sect Patriarch?"

The old man was stunned for a moment, a look of surprise appeared in his eyes, and he replied respectfully: "According to the records of the classics in the Sect of the Sect, this Demon Refining Array was obtained by the Founding Patriarch of the Sect of the Sect when he was training in the Sand Sea. ”

"Hmm!"

Chang Shan nodded, swept around the disciples of the Nine Star Sect, and said lightly: "You guys should leave the sand sea quickly! The aura of the sand jiao on the nine of them is not weak, and it will definitely attract the revenge of the sand jiao." ”

After saying this, Chang Shan didn't wait for the old man to reply, and as soon as he raised his footsteps, he disappeared in place.

The old man was shocked again, and hurriedly summoned out the flying carpet and flew out with all the disciples of the Nine Star Sect.

Chang Shan walked towards the depths of the sand sea while thinking about the purpose of the demon refining array.

"The strange Dan Array of the Demon Refining Array, for Dan Xiu, there should be other uses, the reason why I can't think of it is only because I am not Dan Xiu. Wait until she returns to Tianshan Mountain and show it to Zi Jing, if he says that this Dan Array has other uses for Dan Xiu, he will ask Ying'er to give her a copy. ”

Chang Shan pondered for a while, and a flash of inspiration flashed in his mind, and he suddenly thought of using the Demon Refining Array to cooperate with the Ten Thousand Immortal Array to refine a magic weapon that integrates attack and defense.

In fact, all Instrument Dao Grandmasters must have studied the Instrument Dao, and many Array Dao Grandmasters have also dabbled in the Instrument Dao. Most of the magic weapons in the heavens and the earth were created by cultivators who studied the instrument path, but there were also a small number of magic weapons created by the formation path masters.

The array weapon can be regarded as a magic weapon created by the Array Dao Grandmaster.

Chang Shan didn't have much involvement in the instrument path, if he didn't count the Five Elements Heavenly Wheel array weapon, this time it could be regarded as the first time that Chang Shan wanted to create a magic weapon.

In just a short period of time, Chang Shan came up with a magic weapon in a flash of inspiration and took shape in his mind.

"If this magic weapon is really refined, it will definitely be of great help to me in studying the formation path. When things in Tianzhou settle down, he collected materials and refined this magic weapon. ”

Chang Shan took a deep breath, no longer thinking about the demon refining array, but concentrating on walking towards the depths of the sand sea.

After walking to the depths of the sand sea for almost two more days, Chang Shan suddenly felt a very chaotic aura in front of him, he looked intently, and saw hundreds of sand Jiao wrestling together in the sand dunes in front of him.

Sha Jiao is a demon that lives in groups, and the people of the Nine Star Sect can find a Sha Jiao that happens to be alone and happens to be able to deal with it, because they are lucky enough.

Chang Shan observed for a moment and found that the reason why these sand Jiao were scuffling together was to refine the spiritual power in the body through wrestling.

After observing for a moment, Chang Shan's heart moved, took out nine silkworm cocoons, and refined the demon refining array with nine silkworm cocoons at an extremely fast speed.

After refining the demon refining array, he moved his mind, released the demon binding rope, grabbed a sand Jiao that was cultivated in the realm of the three-grade demon beast, caught it in front of him, and refined it with the demon refining array.

The group of sand Jiao discovered Chang Shan, but they sensed a powerful crisis in Chang Shan, and did not dare to step forward to attack Chang Shan, but fled towards the depths of the sand sea together.

Chang Shan didn't pay attention to the group of sand jiao, and while refining the sand jiao, he perfected the demon refining array according to his ideas.

In the blink of an eye, nine days had passed.

The demon refining array refined the sand jiao, and the nine array flags all contained a cloud of sand jiao's spiritual power.

Chang Shan's mind moved, and the demon refining array changed, and a dark yellow flame condensed by Shajiao's spiritual power appeared in the center of the demon refining array.

Nodding with satisfaction, Chang Shan collected the demon refining array and continued to walk towards the depths of the boundless sand sea.

Although Chang Shan was bold, he walked forward for another nine days before stopping.

At this time, the depth where Changshan was located was the deepest that the Qingdan stage prince of the Yellow Heaven Imperial Family had almost reached every time he entered the Sand Sea.

Chang Shan felt the richness of the spiritual power around his body, causing himself to sink into the sand, while feeling the nature of the rich spiritual power around his body, he absorbed the spiritual power around his body to improve his true yuan.

The process of Chang Shan's understanding of the special features of the earth's spiritual power in the sand sea is actually a process of comprehending the mysteries of heaven and earth.

Cultivators, in the process of comprehending the mysteries of heaven and earth, their cultivation is much faster than that of meditation.

However, after concentrating on cultivation in Shahai for a month, Chang Shan knew that he had chosen to come to Shahai to improve his cultivation, and he had made the right choice.

More than two months passed, and on this day, Chang Shan, who was sinking into cultivation, was awakened by the feeling of palpitations, he frowned tightly, and felt the breath around him.

"Is it a delusion?"

Chang Shan pondered for a moment, his eyes flashed, and he came out of the sand.

The Sand Sea is a place full of dangers, and even if Chang Shan is extremely powerful and has a powerful artifact to protect him, he has to be careful to deal with the dangers that may arise.

Chang Shan's eyes swept around, and then he felt the breath around him, a flash of inspiration flashed in his mind, and he stomped lightly under his feet, causing the sand ripples that would only appear when the wind blew through the sand within a radius of three or four miles.

The moment the ripples appeared on the sand, Chang Shan clearly felt a few breaths nearby, but before he could concentrate on it, those breaths disappeared again.

For a short moment, Chang Shan could only be sure that those breaths were not the breath of Shajiao.

"It's not Shajiao, it's not like Medusa, is it the Sand Clan?"

Chang Shan's heart moved, and there was a strong interest in his eyes.

The Sand Clan is a group that is even more mysterious than the Icemen.

Just when Chang Shan was about to go to the place where the breath appeared just now to investigate, the feeling of palpitations appeared again, and he subconsciously turned his head and saw three strange snakes behind him, surrounding him in an arc.

These three strange snakes, each of which is more than three feet thick, they stand up more than a foot high, with a human-like head, an erect eye in the center of the eyebrows, hair on the head, and a snake head at the end of each hair, which looks very weird. They have two claws in their abdomen, and they have sharp bone spurs on top of each claw.

Medusa, a strange beast that Chang Shan has long heard of in his name, coexists with the people of the Sand Tribe, and is the guardian god worshiped by the people of the Sand Tribe.
