The room was dimly lit, and heat radiated from all sides.

A cauldron and two black iron alchemy furnaces were located in the center of the house. Spiritual energy was rising from the furnace mouths, revealing a pale yellow flame. There were many black medicinal dregs next to the furnaces.

The young man in front of the alchemy furnace had a solemn expression, and beads of sweat on his cheeks were turned into steam by the high temperature the moment they slid down.

Qin Xin had been cultivating elixirs in the courtyard for several days, and the ingredients for the twenty portions of Nourishing Heart Pills he had prepared were almost used up.

To advance from a first-grade alchemist to a second-grade alchemist, one needs to refine a perfect second-grade pill. The refining process for a second-grade pill is much more complex. Qin Xin tried many times, but each time, due to some minor mistakes, all the medicinal materials in the entire furnace were ruined. Moreover, the spiritual energy in the second-grade demon beast crystal is extremely violent. To fully extract and release the spiritual energy within, the alchemist's true qi foundation is also very high.

Qin Xin's gaze was entirely focused on the two black iron pill furnaces. These furnaces had been put into his Qiankun bag and taken away by Ya Ru, but Qin Xin got them back. However, the price Qin Xin paid was that he could not refuse Ya Ru's requests to refine pills in the future.

As for why Qin Xin wanted to take out this alchemy furnace, it was mainly because the fire-condensing array within it had been redesigned by Dan Qing, making it a top-tier second-grade furnace. Such an easily controllable flame furnace was simply unavailable for purchase elsewhere. Furthermore, Qin Xin had insisted that Dan Qing not alter the furnace's appearance; he didn't want to carry a gilded furnace, as that would be too ostentatious.

"This time, we must succeed!"

Qin Xin silently cheered himself on, calming his mind to sense the intensity of the flames inside the alchemy furnace.

Before the alchemy furnace, Qin Xin occasionally waved his hand, and spiritual herbs such as Nourishing Spirit Grass, Solidifying Spirit Flower, Calming Heart Vine, and Hundred-Year-Old Spirit Ginseng fell into his dantian one after another. Based on his previous experience of failed refining and Danqing's guidance, he slowly extracted the essence needed for refining the pills, while the rest were constantly removed.

Although Qin Xin had performed this refining process many times, he dared not be careless in the slightest. Only by refining the purest essence of the medicinal herb could he increase the success rate of alchemy.

After a period of arduous refining, Qin Xin was somewhat exhausted. During a break in the refining process, he took a Qi-restoring pill. Seeing the pale pink liquid in the furnace constantly churning, he breathed a slight sigh of relief, and the flames in the furnace began to diminish.

After resting for a while, Qin Xin solemnly threw in a level-two water-attribute beast crystal. This step was extremely dangerous and was where he had failed the most.

A pale yellow flame slowly rose in the alchemy furnace. The entry of the beast crystal was like a stone thrown into a calm lake, causing a huge ripple effect. The violent energy within almost dispersed the medicinal liquid. Qin Xin gritted his teeth and controlled the flame, forcing all the medicinal liquid together.

Click...click...

Just when Qin Xin thought he would fail again, the water-attribute beast crystal cracked, and the essence in the beast crystal slowly flowed into the medicinal liquid. In an instant, the medicinal liquid changed from a light pink color to a light blue color, and the beast crystal seemed to have lost its energy and turned into white powder, falling into the pill furnace and being directly discharged by the formation inside the pill furnace.

"Life-Refining Elixir Technique! Condense it for me!"

Qin Xin grunted, and flames billowed out from the alchemy furnace, completely enveloping the pale blue medicinal liquid.

Not only did a sizzling sound emanate, but impurities in the medicinal liquid were continuously expelled, and it became increasingly viscous, vaguely revealing the rudimentary form of a pill.

The billowing flames lasted for more than ten minutes. Just as the flames faded, a fragrant aroma of medicine wafted from the two black iron furnaces, filling the air and instantly refreshing the mind.

Qin Xin waved his hand lightly, and a blue pill flew into his hand, a warm sensation spreading from his fingertips throughout his body.

"It's done!"

A smile finally appeared on Qin Xin's face.

I intended to hand the Heart-Nourishing Pill to Danqing, who was standing nearby, so that the teacher could give his evaluation.

"Although it was successful, there were some flaws in the control of the flames, the purity of the refined medicinal herbs was not high enough, the energy in the beast crystal was not fully utilized, and only one pill was produced, so it can only be considered a second-grade primary pill."

Danqing glanced at it and spoke calmly, but his expression showed that he was very satisfied.

To be able to refine a second-grade pill in five days is an exceptionally outstanding talent in alchemy.

Qin Xin did not bask in his joy, but instead struck while the iron was hot and began to refine the remaining medicinal herbs.

After a day and a night of busy work, several medicine bottles were placed in front of the Xuan Tie alchemy furnace. Qin Xin slowly exhaled a breath of stale air and stretched.

Of the remaining six medicinal herbs, four were successfully refined, and one batch even yielded two Heart Nourishing Pills. Upon seeing Qin Xin's success rate, Dan Qing, standing to the side, also smiled.

The high success rate of the pills was mainly due to Qin Xin's discovery of the final step of adding beast crystals. Beast crystals are inherently violent in energy, and if they are directly thrown into the medicinal liquid, a large part of the essence in the liquid will be lost due to the collision of energy. Therefore, when adding beast crystals, Qin Xin would use flames to envelop the beast crystals, extract the pure energy within them, and then integrate them into the medicinal liquid. Although this method is more complicated, it greatly increases the success rate.

Danqing greatly praised Qin Xin's discovery. Because of his strange fire, he could completely incinerate the beast crystal the moment it was thrown into the alchemy furnace, extracting the purest energy. Therefore, he had overlooked this step. Qin Xin's cultivation and strength were far inferior to Danqing's. Obviously, the method Qin Xin discovered would be of great help to his future alchemy.

"Congratulations, you are now a second-grade alchemist, but this is mainly thanks to having such an excellent master as me."

While offering his congratulations in a relaxed manner, Danqing didn't forget to boast a little about himself.

Looking at the white-haired old man in front of him, Qin Xin could only smile helplessly. He had completely figured out Danqing's childlike personality.

After putting the alchemy furnace into his Qiankun bag, Qin Xin looked at the blue-green Nourishing Heart Pill and was somewhat conflicted.

"The pills I refined myself should be fine, right?"

Qin Xin muttered to himself.

After the pills were finished being refined, Danqing asked him to try them himself. Only by knowing the effects and efficacy of the pills could he better sell them. Otherwise, if he hadn't even tried them himself, others would be even less likely to buy them.

"bring it on!"

Qin Xin calmed himself down and, as if he had made full preparations, swallowed the cyan Heart Nourishing Pill directly into his mouth.

Upon tasting the Heart-Nourishing Pill, a warm sensation from the medicine followed, which seemed to be because the pill had only recently been refined.

The medicinal power of the Nourishing Heart Pill is very mild. When it flows into the martial elixir, Qin Xin can feel that the flow of true qi throughout his body seems to become very regular and unaffected by the external environment. His mind and spirit seem to be replenished with energy, and he is invigorated and his thinking is very clear.

"This medicine is probably five times more effective than the Heart-Clearing Pill!"

Qin Xin slowly opened his eyes, surprised. In order to understand the market, Qin Xin had also bought some Qingxin Pills to try out their effects, but the difference between them and Yangxin Pills was huge.

Qin Xin quickly packed up and prepared to first go to the outer courtyard's trading center to sell the remaining five Heart Nourishing Pills, and then buy some more Heart Nourishing Pill ingredients. He wanted to earn more points so that he wouldn't have to worry about points when he went to the Spirit Forging Tower for cultivation.
