"I have no choice but to use sea onyx. ”

"Hmm!"

Chang Shan nodded, glanced at the Crystal Mountain, and said in a deep voice: "The sea agate on our body is enough to obtain thirty soul refining beads, and thirty soul refining beads are enough for us." ”

After saying this, Chang Shan took out another piece of ambergris incense, lit it with the fire of the primordial gods, and burned it.

There was not a single leak, and Chang Shan obtained thirty-three soul refining beads with thirty-three bottles of sea agate solution.

Putting away the soul refining bead in his hand, Chang Shan saw Zuo Xiangnan and An Yuchen looking like he wanted to speak and stopped, he was stunned for a moment, rolled his eyes, looked at the two and asked, "You want to cultivate in Phantom Heaven for a few days?"

"Hmm!"

Zuo Xiangnan nodded, and said in a deep voice: "The spiritual power refined by Yuchen with the ghost soul can purify the true yuan of his subordinates, and it can also improve the quality of his natal spirit treasures. ”

Chang Shan thought for a while, and said in a deep voice: "Let's try it elsewhere, the ghost of the Silver Pill Stage absorbs the fragrance of ambergris too quickly, and we don't have much ambergris on our bodies." ”

Seeing that the two nodded, Chang Shan flew the two of them away from the heavenly road for more than an hour with a nebula, stopped, and then took out ambergris and lit it.

Ambergris attracted a large number of ghosts to approach, these ghosts were attracted by the fragrance of ambergris, and before they could absorb the fragrance of ambergris to make ambergris burn faster, they were left to the south with the silver light illuminated by the moon wheel, and then burned by An Yuchen into spiritual power for the left to the south to absorb and refine.

Chang Shan didn't have much ambergris to prepare, and the three of them stayed in Phantom Heaven for two more days, and then they had to return to Unai because the ambergris was consumed.

Returning to the Cloud Desolate Star, Chang Shan borrowed the spiritual power of the Cloud Desolate Star to quench An Yuchen's Sun Bead with the flame of the Pudu Being's Pearl, and then separated from An Yuchen and Zuo Xiangnan.

After less than a month, Changshan returned to Draco.

Chang Shan gave Yu Huanting and the others a soul refining bead for them to refine, and he himself also refined two soul refining beads.

The Soul Refining Bead melted into Changshan's Yuan Shen, and it didn't bring much change to Chang Shan's Yuan Shen;

Chang Shan used his Yuan Shen power to refine the Soul Suppression Tower, and then he deduced the Zhou Tian Star Dou Great Array.

In the blink of an eye, seven years have passed.

On this day, Chang Shan was evolving the Zhou Tian Star Dou Great Array, and at the same time using the power of the stars to refine the demon bell, and the voice of the Nine Infant Daoist sounded in his ears.

Chang Shan didn't want to see the Nine Infant Daoist, but as soon as the Nine Infant Daoist's words fell, he immediately put away the demon refining bell and escaped out of the Honghua Palace.

When he arrived at the main palace of the Seven Evil Palaces, Chang Shan was surprised to find that there was only one person in the main hall.

"Meet the palace master!"

"Hmm!"

The Nine Infant Daoist nodded, motioned for Chang Shan to sit down cross-legged, and then asked in a deep voice, "How long do you estimate it will take to reach the Great Perfection of the Silver Pill Stage?"

Chang Shan's mind turned sharply, and he said respectfully: "If you put all your energy into cultivation, you should be able to advance to the Great Perfection of the Silver Pill Stage within two thousand years. ”

"Two thousand years?"

The Nine Infant Daoist smiled lightly, with an inexplicable smile in his eyes, and sighed: "If you can't cultivate to the Tianzun realm within two thousand years, I'm afraid that this palace can only pass on the position of palace master to Yun'an." ”

"Has he cultivated to reach the Great Perfection of the Silver Pill Stage?"

Chang Shan was stunned for a moment, and said with a wry smile: "My subordinates are sure that they will die under the Heavenly Tribulation within two thousand years! Back then, the original predecessors had the Heavenly Star and Moon Wheel left by the Heavenly Machine's predecessors, and it was still a little dangerous to cross the small mixed Yuan Tribulation, and the subordinates did not have such a powerful magic weapon as the Heavenly Star and Moon Wheel, and if they were not ready, they would definitely die under the Heavenly Tribulation." ”

After saying this, a faint mockery appeared on Chang Shan's face, and he arched his hand to the Nine Infant Daoist: "Please redeem your subordinates and say bluntly, in the opinion of your subordinates, Li Daoyou has not survived the Tianzun Tribulation." ”

"Was Atomino injured in the Little Chaos Tribulation?"

Jiuying Daoren's brows furrowed slightly, and he spoke again, and the topic had already shifted to Li Yunan.

"You're underestimating him!"

"The subordinates also hope that the subordinates underestimate him, but they ......"

When Chang Shan said this, he sneered and did not continue.

The Nine Infant Daoist shook his head, sighed, and looked at Chang Shan and said: "This palace also knows that Yun'an has little hope of surviving the Tianzun Tribulation, so I hope that you will survive the Tribulation one day earlier and pass on the position of Palace Master to you as soon as possible." ”

Chang Shan was silent for a while, his eyes flashed, and he said in a deep voice to the Nine Infant Daoist: "Thank you for the palace master's kindness! ”

The Nine Infant Daoist nodded, and asked Chang Shan about the mysteries of the Zhou Tian Star Dou Great Array.

Chang Shan's eyes flashed with a different color, and he told the Nine Infant Daoist some of the mysteries of Zhou Tian Xingdou, and asked the Nine Infant Daoist for his understanding of the Zhou Tian Star Dou Great Array, and then, he summoned the Demon Refining Bell, evolved the mysteries of the Zhou Tian Star Dou Great Array little by little, and discussed it with the Nine Infant Daoist.

In the blink of an eye, more than three months have passed.

The Nine Infant Daoist came back to his senses from the mysteries of the Zhou Tian Star Dou Great Array, closed his eyes and pondered for a moment, frowned slightly and looked at Chang Shan, who was looking at him eagerly, his mind turned sharply, and he said in a deep voice to Chang Shan: "Zhou Tian Star Dou Great Array, the first formation in ancient times, broad and profound, only by absorbing the strengths of others, can it evolve to the extreme." ”

"Drawing on the strengths of others?"

Chang Shan muttered to himself, pondered for a while, and frowned: "The cultivation world and the Zhou Tian Star Dou Great Array belong to the same category and have the same level of formation, only the Hun Tian Star Array, how should the subordinates learn from the strengths of others?"

"Zhou Tian Star Dou Great Array, the spiritual power of each formation base is different, if you can find three hundred and sixty-five mysterious formations that evolve the three hundred and sixty-five formation bases of Zhou Tian Star Dou Great Array, if you integrate these three hundred and sixty-five formations with Zhou Tian Star Dou Great Array, you should be able to raise the power of Zhou Tian Star Dou Great Array to a higher level. ”

"This is somewhat similar to the method used by his subordinates to deduce the Ten Thousand Immortal Array back then!"

Chang Shan replied and pondered.

After a long time, the Nine Infant Daoist let out a long breath and let Chang Shan leave.

Chang Shan retreated, pondering, and walked towards Honghua Palace.

The rules of heaven and earth that evolve within a cultivator are unchangeable. Chang Shan's Inner Heaven and Earth evolved Heaven and Earth rules and underwent several major changes, but his cultivation did not cause any problems in the process of changing the Heaven and Earth rules of Inner Heaven and Earth Evolution.

The rules of heaven and earth that evolve within a cultivator evolve in a more complete direction, and there will be no problems for the cultivator himself.

On the contrary, cultivators may suffer great losses in their cultivation due to major changes in the rules of heaven and earth in the evolution of the inner heaven and earth.

Back then, the Xuanqing Daoist forcibly evolved the heaven and earth mysteries contained in the Pudu Sentient Beings Bead, because when he forcibly evolved the heaven and earth mysteries contained in the Pudu Sentient Beings Bead, the heaven and earth rules of his inner heaven and earth were evolving in the direction of degradation.

Chang Shan explained the mysteries of the Zhou Tian Star Dou Great Array to the Nine Infant Daoists, because he had bad intentions and deliberately disturbed the cultivation of the Xuanqing Daoist, so that he didn't have the heart to pay attention to him;

Knowing that the Nine Infant Daoists had bad intentions, Chang Shan returned to Honghua Palace, but while evolving the Zhou Tian Star Dou Great Array, he evolved one formation after another that he had evolved before, as if he was looking for a more perfect formation that could make the Zhou Tian Star Dou Great Array evolve.

In fact, Chang Shan was inspired to use a variety of different formations to comprehend some subtle changes in the Zhou Tian Star Dou Great Array.

In the blink of an eye, more than thirty years had passed, and Chang Shan had encountered a bottleneck on top of the deduction of the Zhou Tian Star Dou Great Array.

Chang Shan is not an impatient person, but he has some other things to do, but for a while he doesn't want to break this bottleneck by spending a lot of time.

He first spent nine years fusing the Mixed Yuan Bead, known as the essence of the Mixed Yuan Stone, into the Mixed Yuan Stick, and used the Zhou Tian Star Dou Great Array to refine the Mixed Yuan Stick, so that its quality was improved to a top-grade artifact, and then he began to refine the twenty-four Zhenhai Pearls of the middle grade artifact level that Yuan Tianlang asked Lu Chengxian to send him.

After refining twenty-four medium-grade artifact-level Zhenhai Pearls, Chang Shan found the Nine Infant Daoist and said that he wanted to enter the Twelve Heavenly Arrays to deduce the mysteries of the Twelve Heavenly Arrays.

The Nine Infant Daoist didn't say anything to let him concentrate on improving the grade of the Demon Refining Bell, so he agreed.

Chang Shan's attainments in the way of water are stronger than his attainments in the path of wood, and his attainments in the water formation are much higher than his attainments in the wood-walking formation, and it only took him less than two hundred years to understand the mysteries of the twelve heavenly arrays.

After comprehending the mysteries of the Twelve Heavenly Arrays, Chang Shan did not leave the Twelve Heavenly Arrays, but laid a more powerful Twenty-Four Heavenly Arrays in the Sumeru Immortal Mansion with twenty-four Zhenhai Pearls in the Twelve Heavenly Arrays.

With Chang Shan's Yuan Shen cultivation, which was much stronger than that of cultivators of the same level, it was also a bit laborious to control the twenty-four medium-grade artifacts of Zhenhai Pearls at one time, so he gave birth to the idea of fusing the twenty-four Zhenhai Pearls into the Huangquan Diagram and using the Water Walking Divine Dragon in the Huangquan Diagram to control these twenty-four Zhenhai Pearls.

As soon as he thought of it, Chang Shan controlled the Yellow Spring Diagram to turn into a sea area, wrapped the twenty-four heavenly arrays composed of twenty-four Zhenhai Pearls, and refined these twenty-four Zhenhai Pearls with his spiritual power.

Due to the presence of the Water Divine Dragon, things went surprisingly well.

Chang Shan successfully fused the Twenty-Four Heavenly Arrays composed of twenty-four Zhenhai Pearls into the Huangquan Diagram, turning the Huangquan Diagram into an artifact with a quality that surpassed that of ordinary high-grade artifacts.

He named the Huangquan map, which fused the twenty-four Zhenhai pearls, as the Twenty-four Heavenly Sea Chart, or Zhutian Sea Chart for short.

It took less than 200 years for Changshan to comprehend the Twelve Heavenly Arrays, and it took more than 1,200 years to melt the twenty-four Zhenhai Pearls into the Huangquan Diagram.

When Chang Shan came to his senses, he calculated the time, and couldn't help but change his face slightly.

"I didn't expect it to take so long to refine a magic weapon. ”

Chang Shan took a deep breath, his mind moved, and he escaped from the Twelve Heavenly Arrays.

He returned to Honghua Palace, felt the breath of Honghua Palace, and went to Tianbaolou to take a look, and saw that Shangguan Qing and the others were safe and sound, and couldn't help but secretly breathe a sigh of relief.
