"In those years, in order to successfully obtain this 'Bone Spirit Cold Fire', I spent eight years in that dark and desolate place. And at the last moment of absorption, even though I was fully prepared, I almost got burned into ashes by this damned thing..." The old pharmacist sighed and shook his head, a rare look of fear flashing across his calm face, it seemed that the experience had left a deep impression on him.

  "Heh heh, although the danger is extremely high, as long as I can get this 'Bone Spirit Cold Flame', everything will be worth it." Yao Lao proudly raised the white flame in his palm and smiled: "As long as I possess this heterodox fire, not only will the medicinal strength of the elixirs I refine be more potent, but also when facing an enemy of the same level, they won't even dare to clash with me head-on."

  Upon hearing this, Xiao Yan gazed at that tumbling cluster of snow-white flames, his face filled with envy.

  Looking at Xiao Yan's envious appearance, Yao Lao chuckled and a sly smile flashed across his face. His tone suddenly changed: "The exotic flame is still quite far away for you. For now, your greatest hope should be to pray that you can become a Dou Zhe as soon as possible."

  With a hint of regret, Xiao Yan nodded and temporarily withdrew his craving for the exotic flames, pulling his mind back to reality.

  Seeing Xiao Yan regain consciousness, Yao Lao smiled slightly, the white flames in his palm constantly surging, clusters of sparks leaping into the air before dissipating.

  A withered palm grasped a sprig of ink leaf lotus and gently tossed it into the flames.

  The ink lotus had just been stained with "Bone Spirit Cold Fire", and in an instant, it was smelted into a ball of dark black liquid. The liquid slowly rolled in the flames, reflecting a faint glow.

  The white flames of the forest were getting more and more intense, but Xiao Yan, on the other hand, made a strange discovery: the air outside the white flames was getting colder and colder.

  Yao Lao's eyes were fully focused on controlling the temperature of the flame in his palm. At this moment, if the temperature rose even slightly, the dark liquid would be incinerated into nothingness.

  After the flame temperature was maintained at a certain limit, a small amount of yellow impurities suddenly appeared in that ink-black liquid.

  Looking at the yellow impurities that appeared in the liquid, Yao Lao nodded slightly and flicked his fingers lightly. A small cluster of ink-black liquid wrapped around the yellow impurities was expelled from the main body by him.

  After the yellow impurities were driven out, some small light yellow impurities appeared one after another behind them, and these impurities were also completely cleaned up by Yao Lao without exception.

  In the continuous burning of the white flame, the volume of the ink-black liquid that was originally enough to fill half a fist had already shrunk to the size of a thumb.

  A deep black liquid slowly churns in the snow-white flames, like a black pearl, mysterious and profound.

  After the first batch of Mo Ye Lotus was calcined to the size of a thumb, Medicine Old stopped continuing to calcine and again put in the other four, refining them all into four drops of pure liquid like black pearls.

  After a long period of calcination by the "Bone Spirit Cold Fire", the five small liquids gradually merged, and after merging, their volume expanded greatly. However, this phenomenon only lasted for a moment before they shrunk back to their original size.

  After rolling in the flames for a long time, even in that dark liquid, it seemed that a cluster of white flames could be seen dancing.

  Seeing this scene, Yao Lao's palm quickly grabbed the snake gall fruit on the table and threw it into the flames.

  As soon as the snake's spittle entered the flames, it transformed into a pool of pale green liquid emitting wisps of cold air. The old man quickly skimmed off the impurities from the surface of the pale green liquid and slowly covered it with the pitch-black liquid that was also emitting flames all over its surface.

  "Rustling..."

  Two liquids with different properties came into contact, and a burst of strange sounds suddenly erupted. A faint white mist rose from the flames.

  The white gas gradually weakened, and a rough-surfaced dan medicine embryo quietly took shape in the flames.

  Gazing calmly at the Dan medicine that had already taken shape, Yao Lao nodded slightly and once again added the Jiling Grass and the water-attribute second-grade magic core into it.

  Melted into a liquid, impurities removed, merged together... several intricate and delicate steps, the medicine was almost completed in one breath, without any stagnation.

  When he saw Yao Lao's swift and precise movements, even Xiao Yan, who was still a novice at refining medicine, couldn't help but secretly praise him in his heart.

  After calming down the violent energy in the magic core with the Spirit Gathering Grass, a gentle blue pure energy slowly poured into the embryo of the elixir.

  When the last drop of blue energy entered the elixir, the bumpy surface of the elixir embryo was instantly repaired to be round and smooth, with a faint blue glow floating on its surface, dyeing it into a beautiful and magnificent color.

  After completing these steps, Yao Lao did not immediately withdraw his hand, but instead simmered the elixir in the flames for nearly ten minutes before the white flame in his palm slowly went out.

  When the flames disappeared, Yao Lao's left hand suddenly swept over a jade bottle on the table and then poured the Dan medicine with a hint of pale blue into it.

  "Heh..." A long sigh of relief was let out, Yao Lao casually tossed the jade bottle to Xiao Yan and said lightly: "Take a look."

  Carefully taking over the jade bottle, Xiao Yan was slightly excited to put it under his nose and sniffed lightly, a familiar fragrance wafted out from it, which made his spirit refreshed.

  Looking at the blue and green alternating Dan medicine in the bottle, Xiao Yan relied on his excellent spiritual perception to vaguely know that this Aggregation Powder was absolutely stronger than the one Nalan Yanran took out last time in terms of grade and medicinal power!

  Recalling the woman's condescending look and tone when she handed him the Dan medicine that day, Xiao Yan smiled lightly, with a hint of subtle mockery in his smile.

  Shaking his head, Xiao Yan tightly grasped the cool jade bottle and let out a deep breath. After three years, he could finally set foot in that realm once again...
