For more than ten days in a row, Chu Muyun was repeating the same thing.

Whenever the first beam of winter shines into the room from the window, he is already standing in front of the Dan furnace in the stone room, and then makes a small Tsing Yi Dan Tong to help the master select spiritual materials, and occasionally extract the essence of spiritual materials on the side.

Every day, he would spend eight hours in the stone chamber. He learns that the stone chamber is dark, and that it becomes even darker when the beam of light in winter shines on the outside of the stone door. Fortunately, there is a flame burning, and there is light.

How beautiful and tragic is this process of burning fire crystal.

And when the sunset was asleep and the moon was gradually going up the tall building, he sat cross-legged in the room again, running the "Dishui Spiritual Formula" for a few weeks, and then used spiritual power as ink and fingers as pens to outline a pair of spiritual patterns. These spirit patterns are all spiritual materials used in alchemy during the day, and after observing them for a long time, they will remember them deeply.

From the memory of the fused wisp of remnant soul, he mastered the Tattoo Spirit Realm Magician, outlining the spirit pattern body is pay attention to doing whatever you want, if you can easily outline everything that is at your fingertips and visible at your fingertips, it means that your tattoo spirit realm will be complete.

......

Winter in the Imperial City is dry, and the air is so dry that when the north wind whistles past your ears, it always feels like a knife blade is piercing. Today's imperial city is surprisingly icy rain, the sky is full of dark clouds hovering in the wind, sometimes there are lightning thunderbolts, obviously it is early in the morning, the entire imperial city is shrouded in darkness.

At this moment, Chu Muyun was in deep thought in the stone room. He was still very calm, looking at the Spirit Pattern Pill Pill in his hand, he had a crazy idea, he planned to take advantage of the moment when Elder Liu was not there, and start refining the Spirit Pattern Pill.

After many days of study and observation, he felt that he could try.

As long as in the process of alchemy, the fire crystal is used to ignite the fire attribute demon beast Yuan Dan, which can make up for the defect of not knowing how to control fire.

Among the many elements in this heaven and earth, there is also a difference between heaven and earth in the form of the fire element.

The sorcerer divides the fire between heaven and earth into four types. The most peculiar is the Nanming Lihuo of the essence of the primordial god Nirvana, followed by the fire of the sky flying from the starry sky outside the sky, the third fire is the fire of the center of the earth that exists in the Flame Mountain Range, and finally the fire of the fire attribute demon beast Yuan Dan.

Among them, the fire from the ethereal outer world firmament, it is rumored that there are eight kinds in total, which is also the strongest among many types of fire, except for Nanming Lihuo. Legend has it that no one has ever seen those eight flames.

There were sixteen kinds of Earth-centered Fires in the Heart of the Flaming Mountain Range, and the horror of their flames was second only to the Firmament Fire, and the kind of flame that Elder Liu had mastered seemed to be a kind of Earth-Center Fire.

As for the Yuan Dan in the body of the fire attribute demon beast, strictly speaking, it is not a form of fire-like existence, but it is like thousands of fire crystals, which can continue to burn. For the vast majority of Dan masters who did not fuse fire-like weapons, they all chose the Yuan Dan of the Burning Fire Attribute Demon Beast to control the flames in the alchemy process.

After some careful consideration, Chu Muyun selected the materials needed for the Spirit Pattern Pill from the stone platform where countless spiritual materials were listed.

The refining process of the Spirit Pattern Pill is not too complicated, and there are only five kinds of spiritual materials required, which is very suitable for beginner disciples who have just entered the Alchemy Gate.

Because the effect of the Spirit Pattern Pill is to help the practitioner who has just entered the Spirit Pattern Realm to outline the Spirit Pattern Body, the key to refining this pill is the last step to gather the Pill into a star.

In the stone room, in addition to the big Dan furnace in the center, there are no less than 20 small Dan furnaces arranged against the stone wall around.

When the fire spar burned the body of the Dan furnace crystal red, Chu Muyun took out the five materials one by one, and then flicked his fingers and shot the first spiritual material Nine Leaf Flower into the scorching Dan furnace.

He stretched out his palm, and a second-order fire attribute demon beast's Yuan Dan appeared in his hand, his face showed a solemn color, and he used the fire crystal to ignite the fire attribute Yuan Dan in his palm, and a purple-blue flame burned quietly in his palm.

The palm holding a flame could not feel the scorching temperature, because it was the fire essence contained in the Demon Beast Yuan Dan that was burning, and there was a faint hint of cold in this flame, like the cold ice spiritual power transmitted from the body.

Chu Muyun slowly stretched out his palm, and under the control of spiritual power, the burning flame set off the Dan furnace and began to refine the essence of the Nine Leaf Flower. He carefully followed each step step by step, and put the remaining four spiritual materials into the Dan furnace in turn.

The fire attribute demon beast Yuan Dan burned more and more, and the time had passed unconsciously, and the time for extraction was almost over, so Chu Muyun was ready to withdraw the essence of the material.

As soon as his mind moved, suddenly there was a muffled sound in the Dan furnace, Chu Muyun was dazed, and after retracting the flame in his palm, he used his spiritual power to take out the extracted spiritual materials, only to find that all five materials had been burned.

Chu Muyun frowned slightly, and was not annoyed by this, after all, it was the first time to refine the pill, and failure was inevitable. He seriously reflected on the whole extraction process......

"Maybe I was so cautious that I missed the best time to extract the essence of the material. ”

So he cleaned up his state of mind, walked the whole process in his mind again, and then took out another spiritual material, which was to refine it again......

This ice rain is still falling, the temperature of the cold winter is also dropping, and the raindrops fall to the ground, like round jade beads.

Until dusk, the ground is covered with tiny grains of ice, and pedestrians feel as if they are walking in the snow, reflecting the footprints of coming and going, but they are rarely in the same direction.

Chu Muyun stayed in the stone room for a few more hours, during which he refined the Spirit Pattern Pill four times, but none of them were successful.

After continuous failures, now he has some experience in refining the elixir, at least his ability to extract spiritual materials and his ease of use are much stronger than those Tsing Yi disciples who started earlier.

His talent is still good......

After those five spiritual materials were extracted, they are now being fused. This is the fifth time, and if he fails again, he really needs to go back and rest. Although he had a successful experience of fusion before, he still did not take it lightly.

The fusion of spiritual essence is not only to control the degree of burning of the fire, the use of civil and military fire, etc., but also to integrate a trace of one's own divine soul power into the Dan furnace as a guide to fusion, and this trace of power cannot be more or less.

The Divine Soul sensed that the time had come to inject the power of the Divine Soul, and Chu Muyun continued to control the burning heat of the Demon Beast Yuan Dan, while peeling off a trace of the power of the Divine Soul, and then slowly entered the hot Dan furnace like a trace of thunder arc with the guidance.

At this stage, it is necessary to use martial arts to violently accelerate the fusion.

Chu Muyun was also more focused at the moment, the sweat on his cheeks dripped onto his clothes, and his face was a little pale.

Feeling that the fire essence in the second-order demon beast Yuan Dan in his palm was exhausted, he took out another first-order demon beast Yuan Dan to support the raging flames, the fire snake that seemed to be devouring the Dan furnace, faintly mixed with a slight hissing sound of the air being burned.

Finally, it was time for the last step to gather Dan.

The martial fire was changed to a simmering fire, Chu Muyun closed his eyes and concentrated, concentrating all the power of the divine soul, using the thought as the pen and the divine soul power as the ink, and sketching the spirit pattern body of the seven-star soul rejuvenation grass on the embryonic pill through the Dan furnace......

Finally, he ejected a trace of spark from the Yuan Dan flame of the palm demon beast and poured it into the Dan furnace for the final star-forming work.

This fire represents the quality level of the elixir, and the so-called one-star to nine-star elixir is judged according to the degree of manifestation of that trace of fire on the elixir. After doing all this, Chu Muyun relaxed a little.

Putting away the flame in his palm, all he could do was wait.

Chu Muyun stood up a little tiredly, estimating the time and night should cover the entire imperial city, through the gap in the stone gate, Xi Suo Suo listened to the sound of rain outside, he guessed that at this time, the cold mountain town should be snowing again!

Stunned, the stone door slowly opened, and Elder Liu strode in.

He had a smile on his face, and he seemed to be in a very good mood, perhaps because the falling ice particles had been replaced by flying snowflakes, and the streets of the Imperial City were already faintly visible in the whiteness. No one doesn't like snow, and neither does Elder Liu.

"Where did the Danxiang come from?" Elder Liu put his hands behind his back, raised his pale eyebrows, and looked at Chu Muyun who bowed with a little doubt, and immediately smiled heartily, stroked his beard, and his eyes were full of appreciation: "I originally thought that it would take at least half a month for you to have enough experience to refine the Spirit Pattern Pill, it seems that ...... My apprentice's qualifications are far above that of a teacher!"

Chu Muyun smiled, he didn't know that the master kept the spirit pattern pill for himself, and let himself follow it these days, witnessing the process of alchemy, just to exercise his ability to make alchemy independently.

"Yun'er...... You have to remember that the journey of a sorcerer is like life, and it is important to identify the goal, but ignoring the scenery of the journey to reach the end point is never what you want! If you want to pursue the ultimate of the sorcerer's journey, you must see enough rivers and mountains, and only those who have experienced the Red Dust Dao can ...... be able to break out of the red dust" Elder Liu said earnestly, who would have thought that he had spent more than ten days to let Chu Muyun experience alchemy by himself, and the ultimate goal was just this obscure sentence!

Although it was obscure, Chu Muyun also understood it in his heart.

He knew that his path did not lie in the Dan family, any of the hundred schools was just a scenery for the sorcerer, and his alchemy was just experiencing the red dust......

The twilight of the cold winter shrouded the imperial city, but the imperial city had long been covered by the oppressive dark clouds, and the falling snowflakes were stained with soaked rain, and the fluttering looked a little heavy, just like the shadow of the imperial city reflected in the rain, just like the hurried lines reflected on the snow.
