CHAPTER 1002: CHAPTER 999: PILL FORMATION (PART 1)

"Senior sister, are you talking about the legends of the River Map and Luo Book? The era of Emperor Fu Xi is even older than Emperor Xuan Yuan, belonging to the ancient times before history, and the time-space distance is too vast," Lin Tian said.

"It is rather distant. Speaking of something closer, how do you plan to handle the two-colored potion?" Zi Yan casually mentioned, then returned to the topic of medicine refining.

Lin Tian continued stirring the potion, saying as he stirred, "Use a gentle heat to slowly evaporate the excess water until the two-colored potion is as thick as Jadescent Nectar, which marks success. The temperature must not vary widely throughout the process, otherwise, it will disrupt the separation of the essence and lead to failure in refining."

"Sounds troublesome, I’ll let you focus on medicine refining then, I won’t bother you," Zi Yan furrowed her pretty brows, then stepped aside and fell silent after sitting down.

Lin Tian didn’t mind and continued stirring the potion. When the liquid became slightly thick due to constant evaporation, he swiftly extinguished the flame, letting the residual heat of the cauldron evaporate the moisture.

When the cauldron completely cooled, the potion’s thickness matched what Lin Tian described, with red and black colors akin to Jadescent Nectar. Moreover, Lin Tian could clearly sense that this potion contained a rich vitality.

This vitality seemed to resonate with the aura of the sea eye, and Lin Tian realized he had chosen the right place. The sea eye was like the source of life nourishing plants, and it also locked in the vitality of the Yin Yang Life Fruit, preventing excessive loss.

Lin Tian poured out the two-colored potion and stored it all in a glass bottle.

"Finally extracted successfully," Zi Yan breathed a big sigh of relief, smiling happily, "Do you need rest, or proceed with the final fusion?"

"My stamina is freakish, doesn’t matter, just worried about senior sister not bearing it," Lin Tian chuckled lightly, returning Zi Yan’s earlier statement to her.

He thought Zi Yan would exert her seniority authority and give him a lecture, but unexpectedly, she sighed, "Alas, your freakish stamina, I wonder if your future woman will be fortunate or unfortunate?"

The remark was incredibly serious. Lin Tian blinked in confusion for quite a while before realizing, thinking innocently that you never know where your senior sister’s teasing will come from, and he had fallen for it again.

"Alright, senior sister, you win," Lin Tian admitted helplessly.

Zi Yan just needed to undo a single button for her teasing power to exponentially rise, dispelling the need for combat.

Lin Tian withdrew his gaze from Zi Yan and began organizing the extracted essence of medicinal materials, arranging bottles and jars into two huge circles, totaling twenty bottles of herbal essence.

"Senior sister, I’m about to begin. Soon, you cooperate with me in deploying the herbal essences. These twenty essence bottles, do you remember each name and their characteristics?" Lin Tian asked, looking up.

"Of course, I’m trained in medicine, this level of difficulty is nothing," Zi Yan replied confidently.

Lin Tian nodded, reignited the carbon crystal, then picked up two types of medicinal materials and threw them into the cauldron. Following Lin Tian’s instructions, Zi Yan also added two types of medicinal essences.

Blue flames began calcining the essence within the cauldron. Every few minutes, Lin Tian and Zi Yan would add one or two types of herbal essence, mixing various colors of medicinal materials: powders, liquids, and even semi-solids, achieving initial fusion under the flames.

Lin Tian opened the last bottle, pouring in all the essence of the Yin Yang Life Fruit. The moment the two-colored potion entered, it instantly fused all the earlier materials within.

Though the Yin Yang Life Fruit was difficult to refine, its gentle medicinal property made it easier to integrate, without causing significant conflicts with other materials.

However, Lin Tian remained cautious, meticulously controlling the flame. His patience left Zi Yan staring wide-eyed; clearly, Lin Tian had the makings of a pharmacist, his sheer patience surpassed many pharmacists, Zi Yan thought with satisfaction.

The more skilled Lin Tian was, the happier Zi Yan, as senior sister, felt.

As the flames calcined, the mixed herbal essences further fused and contracted inward. Previously, a large lump of semi-solid medicinal essence dried up, transforming into a complete solid, shrinking by more than half.

As the size decreased, the shape of the elixir gradually appeared, though its color still mixed considerably, and the exterior lacked smoothness, still a few steps from becoming a completed elixir.

Seeing the medicinal essences fused to such an extent without violent conflicts, Lin Tian slightly relaxed, relying on everyday training methods, analyzing many details beforehand unlike many pharmacists whose medicine refining involved unknowns, Lin Tian had more assurance.

The last steps were crucial too. Lin Tian suddenly increased the intensity and the previously calm blue flames surged dramatically, completely enveloping the cauldron’s base.

The result was an immediate temperature rise inside the cauldron. Even Zi Yan felt the intense heat emanating from the cauldron, multiplying several times from before.

Lin Tian certainly intended not to destroy the elixir but to use the fierce fire to complete the final calcining, ensuring all herbal essences fused thoroughly.

The rising temperature gradually softened the surface of the elixir, and the jagged parts became rounder, with the shape more closely resembling the roundness of an elixir.

"Senior sister, add more carbon crystal, and further increase the flame," Lin Tian instructed once again.

Without asking why, Zi Yan simply followed Lin Tian’s directions, adding carbon crystals to the fire chamber of the cauldron.

The addition of reinforcements caused the flames to surge dramatically again, with the temperature inside the cauldron snapping even higher, the elixir’s volume decreased further, and the surface discoloration vanished, leaving only red-black colors.

As the temperature soared again, the red-black colors faded, replaced by a subtle golden hue, shinier than yellow but softer than pure gold, with the surface becoming exceedingly smooth.

Upon seeing the appearance of a pale gold, Lin Tian immediately extinguished the flame. Though Zi Yan couldn’t see what happened inside the cauldron, Lin Tian’s actions indicated the medicine refining was nearing its end.

Though she wasn’t a pharmacist nor had she refined medicine, learning medicine under Jiang Xiu Ying taught her the common knowledge of medicine refining, knowing its conclusion was vital, potentially affecting the elixir’s final quality since it constituted the brewing of medicinal potency mixed into an integral whole.

Zi Yan eagerly anticipated what level of quality elixir Lin Tian would create; the better the quality, the more effective the treatment.

As the cauldron cooled completely, Lin Tian opened the cauldron lid, revealing a rounded pale golden elixir. Under the moonlight, its smooth surface reflected a faint halo, as if the elixir was glowing.

"This...the Yin Yang Life Elixir shows a halo. Could it...could it be a superior elixir?" Zi Yan gasped, intermittently exclaiming as she watched the elixir at the bottom of the cauldron.
