Three days later, Lin Yun returned to the basement of his villa, burned incense and bathed, sat cross-legged, his eyes closed, and carefully recalled the alchemy method in the "Encyclopedia of Elixirs".

There are four steps in refining the elixir.

The first step is to first melt the elixir and herb into juice, and then remove the impurities in the elixir juice. The higher the quality of the refining elixir, the more sufficient the aura will be, and the stronger the effect will be.

The second step is to fuse the purified elixir juice with each other, which does not seem simple but requires strong spiritual power and fire to control the fusion.

The third step is Ning Dan, if you Ning Dan, you need to master the heat, the fire is too big and the Dan is destroyed and scorched, and the fire is too small to condense into a Dan shape.

The fourth step is Yun Dan, when condensing the Dan, some aura will escape in the Dan furnace, and Yun Dan will absorb the spirit pill in the Dan furnace to absorb the scattered aura, which is conducive to the improvement of the quality of the pill.

Lin Yun recalled the aftermath of alchemy, and summed it up in his heart, in short, alchemy is to master the heat well and have strong mental strength.

Immediately, after Lin Yun had a plan in his heart, his heart moved, and the person had disappeared into the basement and entered the Imperial Spirit Ring.

In the land of Yimu in the east, in addition to the ginseng, Ganoderma lucidum, and Polygonum multiflorum planted by Lin Wan before, the elixirs needed to refine Huanglong Dan, Purple Ginseng Dan, and Lianqi Pill were all planted in the land of Yimu.

The spirit ring has a ten-year effect in one day, and most of the elixirs of Huanglongdan only need ten or dozens of years of elixir to make, and they have been cultivated for a few days.

At this time, the elixirs for refining Huanglong Dan had already met the requirements, and after some of these elixirs matured and became planted, Lin Wan continued to plant them one by one.

Pieces of medicinal herbs are thriving, growing very well, and Lin Yun's heart is full of joy when he sees it.

In addition to the ginseng, Ganoderma lucidum, and Polygonum multiflorum that Lin Wan first planted for thousands of years, the rest of the elixirs are about 80 years at most.

Lin Yun thought in his heart, if he wanted to refine the pill now, at most there would only be seven or eight furnaces to refine the elixir of the Huanglong Pill, as for the Purple Ginseng Pill and the Qi Refining Pill, then some of these elixirs had not reached the required year, and the steps were enough to refine the elixir.

Lin Wan planned to wait for three days, and after three days, a batch of elixirs would mature, and there would be no elixir refining at that time.

Immediately, Lin Yun's heart moved, and he came to the pass of the Nanmingdi Fire Volcano in the south.

Wisps of earth fire kept jumping in the crater, flashing with red brilliance.

Lin Wan sat cross-legged, and as soon as his heart moved, he waved towards the beast control with one hand.

After the beast control tripod spun around in the void of the Imperial Spirit Ring, it suddenly shrank and flew towards Lin Yun's palm.

Lin Yun naturally planned to use the Beast Control Ding and Nanming Earth Fire to refine the spirit pill, otherwise, he would rely on his own cultivation of the first level of qi cultivation to refine the spirit pill by himself, which would be a big joke.

Lin Yun glanced at the miniature version of the beast control tripod with a reduced palm, and his heart also moved, and he lifted it with one hand.

With a "boom" sound, the beast tripod rose in the wind, and the three-legged tripod stood under the volcano.

Wisps of earth fire spewed on the beast dominator, and disappeared in the blink of an eye.

Lin Yun planned to use these three days to skillfully control the earth fire and use it for alchemy.

Immediately, Lin Wan pinched out a trick and slapped the crater.

"Buzz". A sound came.

Fire dragons erupted from the volcano, and the dragons flew and danced straight towards the Beast Riding Ding, as if they wanted to directly engulf the Beast Controlling Ding.

Immediately, Lin Yun's divine sense controlled the size of the fire, and he was proficient in the earth fire of this volcano......

The three days continued to control the size of the fire in Lin Yun, and it passed in a flash.

At this time, on the ground next to the crater, a pile of elixirs was placed, and these elixirs were divided into more than thirty parts.

These elixirs were the elixirs that had all matured to refine the Huanglong Pill, and after three days, Lin Yun had gathered thirty-six elixirs for refining the Huanglong Pill.

Immediately, after Lin Wan was ready.

After pinching out a magic trick and slapping the volcanic ground, flames the size of a fist erupted from the crater.

Under the beast ding, it kept turning, and constantly began to preheat the Dan furnace

A quarter of an hour later, after Lin Yun saw that the Dan furnace had been preheated, he waved his left hand, and the elixir for refining the Huanglong Pill next to him was put into the Beast Riding Ding one after another, refining it into juice.

Lin Wan carefully controlled the heat, and after three minutes, these elixirs melted into juice and turned into a cyan-colored liquid.

After melting into juice, Lin Wan began to increase the heat, and began to purify the impurities in the elixir juice, only to see Lin Wan increase the heat, and some gray-black mist appeared in the clump of elixir juice, which emitted from the clump of elixir juice, and was refined into ashes by the temperature in the Dan furnace after a while.

Previously, Lin Wan only controlled the fire, there was no elixir in the Dan furnace at all, and there was no scruple at all, at this time, Lin Wan was single-minded, and he needed to take care of the elixir in the Dan furnace on the one hand, for fear that his hands would tremble, and the fire would be too big, so he would directly burn the elixir in the Dan furnace, and he also needed to control the fire carefully.

At this time, the sweat on Lin Yun's forehead was constantly falling, and his face was pale, at this time, Lin Yun had just practiced the cultivation of the first layer of qi, refining the elixir was already very reluctant, Lin Yun's own spiritual energy had been almost exhausted, and he was all relying on a strong perseverance to persevere.

Lin Wan wanted to work harder to refine the Huanglong Pill, and the Ning Dan came out of the oven, the aura was suffocated, and a burning smell came from the Dan furnace, and Lin Wan knew that this furnace of the Spirit Pill had been scorched and the practice was wasted.

"Whew". Lin Wan was panting heavily. The spiritual power was exhausted, and he looked tired, and then, he closed his eyes and ran the exercises, slowly recovering the consumed spiritual energy.

Three hours later, Lin Wan recovered his aura, Lin Wan felt that he had exhausted his aura, and after recovering, he felt that his aura was more refined and improved.

Subsequently, Lin Wan slowly pondered the shortcomings of his previous alchemy.

The key to oneself is that one's cultivation is too low, and one's own aura is not enough to refine a furnace of elixir, and the aura will be exhausted, which is not enough to support it.

After figuring it out, Lin Yun glanced at the dozens of elixirs beside him, he had the Imperial Spirit Ring in his hand, he was not afraid that there would be no materials to practice his hands, and Fang Zheng was also a free alchemy material, so he didn't need to use it in vain, so as not to waste the effect of this anti-heaven Imperial Spirit Ring.
