Xuantian Immortal Cultivation Record

At this moment, the water and fire spiritual power within Zhang Yuanjing's body was still abundant. If it wasn't used for refining pills, he could only exhaust it through cultivating the Thick Earth Transformation Art.

He thought that there were only five pills in total, fewer than the medicinal materials, so he simply took out four middle-grade spiritual stones and inserted them into the array slots. Then, he took one each of White Cinnamon, Jade Leaf, and Red Fruit, opened the furnace lid, threw them directly into the furnace, and started the Yang Fire to scorch them.

Under the extremely high temperature, the three spiritual objects did not ignite or scorch. Instead, they quickly turned into liquid, with water droplets carrying impurities flying out from time to time.

After three breaths, he immediately stopped the Yang Fire and switched to Yin Fire. The temperature dropped slightly, becoming more stable. The spiritual objects continued to liquefy, but it was unusually calm.

After three breaths, he switched back to Yang Fire. Bubbles occasionally emerged from the liquefied spiritual objects, and when the bubbles burst, they turned into splashing droplets of water.

After alternating between Yang Fire and Yin Fire three times, the three spiritual objects completely turned into liquid, but there were still many useless impurities remaining. Next was the process of using Yang Fire to force out impurities and Yin Fire to refine them.

Both took six intervals of three breaths, but there was a small problem in the connection, which was the sudden increase and decrease in temperature. This had a slight impact on the Yin Fire used to temper impurities. Therefore, after the three breaths of Yang Fire, an interval of one-third to one-quarter of a breath was needed to minimize the interference of Yang Fire on Yin Fire. This was a test.

Zhang Yuanjing didn't connect well the first time and was a little slow, which caused the temperature of the subsequent Yin Fire to be slightly insufficient. The second time, he adjusted and achieved perfect coordination. After that, he made no mistakes in the next five alternations.

At this time, he entered the second stage of refining the益神丹 (Yi Shen Dan - Mind Enhancement Pill), which was the process of the medicinal liquid condensing into pills. Transitioning from the first stage to the second stage was the second test. To ensure the balance of the two fires, the final Yin Fire of the previous stage had to be stopped one-third to one-quarter of a breath in advance. After the fire completely subsided, both Yin and Yang Fires were released simultaneously.

With the rhythm he had grasped earlier, Zhang Yuanjing did not make any mistakes during this stage transition and passed the test smoothly.

Burning with both Yin and Yang Fires at the same time was a process of further purification. The more violent Yang Fire forced out the deepest hidden impurities, and then the stable roasting of the Yin Fire refined them. This continued for a certain period of time until the impurities were completely removed, and the medicinal liquid would form pills under the burning of the two fires.

Here was the third test, which was the balance of the two fires. The violence of the Yang Fire could not affect the stability of the Yin Fire, and the refinement of the Yin Fire had to keep up with the rhythm of the Yang Fire.

This test was the most difficult. Qin Wutong had failed here. As soon as Zhang Yuanjing entered the stage of simultaneous release of the two fires, the problem of mutual interference immediately appeared. First, the Yin Fire became disordered, and then the Yang Fire was extinguished midway due to the accumulation of too many impurities. Thus, this attempt to refine the Mind Enhancement Pill failed.

Qin Wutong did not offer any good ideas in the jade slip regarding the problems in the second stage, believing that there was no other way than practice makes perfect.

Zhang Yuanjing estimated that each time he consumed a pill from the Crimson Cloud Palace, he could only refine pills twice. Although there was still a lot of remaining medicinal power, it was incompatible with his cultivation method. He had to seize the time to meditate and refine it, otherwise he would easily suffer from pill poisoning. Thus, relying on the remaining four water and fire attribute pills, he could refine the Mind Enhancement Pill at most eight more times. Of course, the Fire Dragon Pill also had an effect, but it was too difficult to maintain the balance of Yin and Yang power.

He sat cross-legged, reflecting on the process of refining the pill just now, carefully savoring every detail, learning from the lessons, and gaining a lot. He also came up with a clumsy method to solve the problem in the second stage, which was to slightly weaken the Yang Fire or Yin Fire, or to weaken both at the same time, to reduce interference.

Of course, which one would work needed to be tested. The reason why Qin Wutong couldn't think of this method was because he always started from the perspective of one portion of medicinal materials to think about solutions.

After resting for half an hour, Zhang Yuanjing began refining the pill for the second time. This time, the first stage was flawless, and the transition from the first stage to the second stage was also perfect. Entering the second stage, he weakened the Yang Fire by 10%, while the Yin Fire remained unchanged. The first ten or so breaths were still relatively harmonious, but afterwards, a situation of mutual restraint began to appear, and finally the Yin Fire became disordered, leading to failure.

However, this failure showed that his method was effective, and it was indeed to weaken the Yang Fire, but 10% was not enough, it had to be more.

Subsequently, Zhang Yuanjing immediately began refining the pill for the third time. This time, after entering the second stage, he weakened the Yang Fire by 20%. After more than twenty breaths of stable burning, just as he thought he was about to succeed, the Yang Fire went out. This was because the Yang Fire was too weak.

After resting for a quarter of an hour, he took the third pill from the Crimson Cloud Palace and began refining the pill for the fourth time. After perfectly entering the second stage and weakening the Yang Fire by 15%, the two fires entered a state of balanced co-burning. Ten breaths, twenty breaths... thirty-three breaths, the medicinal liquid turned pure black and began to condense into a solid mass.

He immediately retracted both hand seals, extinguished the Yin and Yang Fires, and then opened the furnace lid. He scooped it out with his mana and pulled it out. The hot, unformed medicinal mass instantly solidified and fixed, turning into several round, dark black pills.

Zhang Yuanjing focused his eyes and counted, there were a total of five pills, each about the size of a broad bean, with a faint light flashing on the surface, which was very mysterious.

At this time, a thought came from the Yin Yang Creation Furnace: Congratulations, you have passed the first level. Submit one Mind Enhancement Pill to receive the corresponding reward and obtain the next level's mission.

Zhang Yuanjing was overjoyed and slumped to the ground, laughing loudly. After a while, he found that the water and fire spiritual power in his body was overflowing, so he quickly jumped up and continued to refine pills.

This time, after reaching the second stage, he adjusted the amount of reduction in the Yang Fire's power to 13%. Under this ratio, the Yin and Yang Fires still maintained balance throughout the entire process. At the thirtieth breath, he refined a pure black medicinal liquid and successfully condensed pills. This time, he only obtained four pills, but the quality was significantly higher than the previous batch.

According to the pill formula, the Mind Enhancement Pill is a pill that enhances the divine soul, and it is effective for both humans and demons. However, it has little effect on those with strong divine souls.

Because Zhang Yuanjing knew that the growth cycle of these three medicinal materials was very short, he did not believe what the pill formula said. He picked out the best one from the nine pills, smelled it, and felt that it was not a poison, so he opened his mouth and swallowed it.

The pill tasted slightly astringent when it entered the mouth, and it was very hot when it entered the throat. After entering the abdomen, a cool spiritual power emerged and went straight to the Niwan Palace along the meridians. Upon entering the Niwan Palace, this spiritual power wandered around and quickly disappeared into it. Immediately, he felt that the Niwan Palace had expanded by a circle, and the divine soul had also strengthened by 10%.

It can actually strengthen the divine soul! What kind of spiritual plants are these so-called White Cinnamon, Jade Leaf, and Red Fruit? They are simply heaven-defying!

Zhang Yuanjing jumped up excitedly and paced back and forth in the room.

His divine soul power was only average, weaker than most cultivators in the same realm. Now that he had this Mind Enhancement Pill, he could naturally quickly make up for this shortcoming.

According to Guo Yuqing's pill refining notes, for all pills, if the medicinal effect is above 60% and below 70%, it is considered low-grade; above 70% and below 80%, it is considered mid-grade; above 80% and below 90%, it is considered high-grade; above 90% and below 95%, it is considered top-grade; above 95% and less than 100%, it can be called supreme-grade; 100% is a perfect pill.

Because his Mind Enhancement Pill had slightly weaker Yang Fire, there were actually many impurities remaining, so the medicinal properties should be below mid-grade. If he could improve the quality of the pill in the future, the replenishment to the divine soul would naturally be much stronger.

He walked to the bookshelf, placed a high-quality Mind Enhancement Pill in his palm, gently lifted it up, and leaned against the cabinet door.

With a "whoosh," the pill disappeared, and then a thought appeared in his mind: Refining the Mind Enhancement Pill was successful, obtaining a mid-grade pill, a fixed reward of a Soul Ring, and a choice of rewards - a pill formula or the qualification to be a candidate for the owner of the Yin Yang Creation Furnace. Please make a choice within five breaths, five, four, three…

"Choose the qualification to be a candidate for the owner of the Yin Yang Creation Furnace!"

Zhang Yuanjing hesitated for a moment and chose the latter as if possessed. Because, at that moment, a thought flashed in his mind: If the pill formula given by the Yin Yang Creation Furnace was used before ancient times, then without this furnace, any pill formula would be just a piece of waste paper.

"Congratulations, candidate, you have chosen an extremely difficult path. Perhaps until the end of your life, you will still not see the main body of the Yin Yang Creation Furnace. However, you have after all experienced the scenery that ordinary cultivators cannot experience. What a glory, what an achievement this will be! Are you ready? If you are ready, the endless road of trials is about to begin! Five, four…"

"I'm not ready yet!" Zhang Yuanjing shouted quickly, almost tripping over his tongue.

He suddenly thought that if this thought was transmitted by the Yin Yang Creation Furnace's artifact spirit, then it was obviously teasing him. No artifact spirit that has left its original owner would still think about finding a new owner for itself. Therefore, this so-called "owner candidate qualification" was probably forever a "candidate," but he would become a toy for this artifact spirit to entertain itself!

"…" After a few breaths of silence, the thought came again, "The trial is suspended. No penalty for the first suspension. Giving a token - a low-grade replica of the Yin Yang Creation Furnace, which can be used for refining pills and can be used as a token to enter and exit the Yin Yang Creation Furnace's avatar. The next time you enter, the second level's trial mission will automatically begin, it cannot be suspended, and it cannot be abandoned."

With a flash of white light, a three-inch-tall miniature Yin Yang Creation Furnace appeared in front of Zhang Yuanjing. He reached out and caught it, and his divine sense intervened, and he immediately understood its function: it can be used to refine pills at or below the Golden Core realm, and the quality is guaranteed as if it were the Yin Yang Creation Furnace's avatar; it can be held as a token to fly out of the Yin Yang Creation Furnace's avatar; if the holder enters within a ten-thousand-mile radius of the Yin Yang Creation Furnace's avatar, they can be teleported directly into the avatar's body.

Afterward, a one-inch-long black ring floated in front of him, which should be the "Soul Ring" that the thought mentioned.

He communicated with his divine sense, and the information of this object was presented: it was refined from a rare spiritual object called Soul Tendril Grass, which can be used to imprint a divine sense brand and seal it into the brain of a demon beast to enhance its divine soul and affinity to oneself, increase its cultivation speed, and become a battle partner; if the demon beast breaks through to the Transformation realm, it can completely refine this object.

Finally, the information accompanying the Soul Ring also suggested using it on the Golden-Backed Giant Ape. This ape is an ancient alien species with very high aptitude and great potential. It is a spiritual beast raised by the original owner of the Yin Yang Creation Furnace. Once a partnership is formed, it will be loyal forever.

Of course, there is also a condition for using it as a partner, which is that one must continuously provide it with pills for cultivation, especially pills that enhance the divine soul. In the early and mid-stages of the demon core realm, it is the Mind Enhancement Pill, and in the late stage of the demon core realm and above, higher-grade pills are needed.

He moved his divine sense, trying to put the Soul Ring into the storage bracelet, but this object floated in the air, motionless. He had no choice but to reach out and hold it up, and the Soul Ring fell into his hand, as light and soft as cotton wool, and like a cloud of smoke. He sighed helplessly: becoming this damned "candidate" is indeed a series of traps, and it is not easy to get rid of it.

The reason why the golden-backed giant ape outside brought him so excitedly to the place where the Yin Yang Creation Furnace's avatar was located was probably because it wanted this Soul Ring. How dare he ignore its existence and leave directly with the Soul Ring.
