"Put the inner elixir into the Yi Hua tripod and refine it into a demon core for storage." The purple-robed figure appeared in the sea of consciousness at the right time, handed Zhang Ye a formula, and then left.

  Zhang Ye followed the instructions and placed the inner elixir of the Beila Haiyao into the central dan mouth above the Yi Hua Ding.

  Yi Hua Ding is extremely precious, ranking among the sixth-grade treasures. It has been a renowned magical instrument for over 500 years. Inside, it features a special Da Liu Yang Huo array for the Hui Chun Men, as well as four separate fire arrays. In the center lies one Dan mouth, while on the top and sides are four additional Dan mouths, totaling five mouths that can simultaneously refine five elixirs in one furnace.

  After accompanying the good medicine, Zhang Ye's palm pressed on Yihua Ding, and after the true energy was injected, it was loud.

  In the crystal-clear Yihua Ding, one can clearly see the six yang fires burning vigorously inside.

  At present, Zhang Ye has entered the second layer of Fen Shen, and with his thick foundation, he is almost catching up to the strength of the fourth layer of Fen Shen.

  Although it's not fully utilizing Yi Hua Ding's strength, without using the Splitting Fire Array, just using the Great Fire Array is more than enough. The precision of fire control is exquisite, even Ziyi who was observing from the Sea of Consciousness was moved.

  The fire in the stove suddenly became larger and smaller, higher and lower.

  After a long time, Zhang Ye's magical powers were withdrawn, and he let out a cold snort.

  The fire went out, and in the faint smoke, a bloody smell wafted.

  "This situation shows that the poisonous evil and Jie Qi that Bella's demon had been harboring in her Dantian were all refined by Yihua Ding. You're lucky to have gotten Yihua Ding's help, if you used Wuling Shen Ding instead, although it could also refine them, it wouldn't be as easy, and the loss would be much greater." Zi Yin said in the sea of consciousness.

  Zhang Ye hastily opened the furnace to take a look, and in the central dan mouth, that huge inner dan that was there before had disappeared, replaced by seven dark and shiny yao nuclei arranged in a row.

  Zhang Ye quickly put away the stored items.

  There are currently twelve You nuclei, which can be refined to increase lifespan, and are extremely important for Zhang Ye at present.

  Then, Zhang Ye glared fiercely at that pile of Bella Sea Demon's things and said: "You should teach me how to use those things now? I almost died nine times to get them back."

  "You're exhausted today, take a rest first. We'll start tomorrow." Ziyi slightly raised her chin, "The dragon's body is full of treasures, these dragon scales and bones are also hard to come by, they're the best materials for refining magic artifacts. In principle, since you've entered the divided spirit realm, you can imbue magic artifacts with spiritual energy, so you can refine magic artifacts. However, under normal circumstances, those in the third layer of the divided spirit period or below can only refine second-grade magic artifacts, even if you're special, you can only self-refine third-grade magic artifacts. But now that you have Yihuading's assistance, you might be able to forcibly refine a fourth-grade magic artifact, though it's quite dangerous."

  Zhang Ye listened attentively. These were actually the diary experiences given by Master Wang Siqi, which had been explained in great detail. Zhang Ye already had a certain understanding of them.

  In general, when people refine artifacts, there are too many taboos. For example, the level of the artifact being refined must not be higher than that of the furnace and cauldron. Especially for refining flying swords with a heavy murderous aura, a sixth-grade furnace and cauldron can only refine fifth-grade flying swords. Otherwise, it is very easy to cause "usurpation", where the flying sword's primordial spirit will awaken and overpower the furnace and cauldron.

  Therefore, the five treasures of the law are even more precious and rare.

  In addition to the requirements for the furnace, there are also very strict requirements for the practitioner himself. Since ancient times, there has been a saying that "dedicates one's life to the sword" and thus achieves the divine sword. The formation of high-quality artifacts requires too much spiritual energy and divine consciousness from the practitioner themselves. Practitioners must separate their own essence and spirit, enter the material, participate in forging, and make the artifact produce willpower.

  However, this process is extremely dangerous and it's easy to be counterattacked by the evil energy of the magic treasure during the "distraction" forging, which requires that the cultivator's cultivation must be far higher than the magic treasure in order to be safe.

  In general, cultivators in the scattered spirit period can at most refine third-grade magic treasures, while golden elixir cultivators can refine up to fifth-grade magic treasures. Sixth and seventh grade magic treasures must be refined by strong nascent soul masters to ensure safety.

  As for the legendary self-contained spirit treasure of the eight-rank method, it must enter the Transcendent Immortal Realm to be accomplished.

  Divine transformation, in itself, requires the practitioner to transform their entire body into divine consciousness, enter the interior of the Dharma treasure, construct a new realm, and grant the materials of the Dharma treasure the strongest mental power. Afterwards, it is as if the practitioner has "given birth" to something within the Dharma treasure. After the construction is complete inside the Dharma treasure, it helps give birth to an instrument spirit. To be honest, that instrument spirit is directly equivalent to the child of the Dharma treasure and the practitioner's original spirit.

  "For safety's sake, you can only refine three types of magic treasures for now." The purple-robed figure interrupted Zhang Ye's thoughts. "However, these parts of the Bella Black Python's body do not require you to refine new magic treasures. Your four-grade flying swords have already taken shape and carry spiritual energy, so you don't need to divide your attention among them. This way will be much easier. Tomorrow, I'll teach you how to re-melt the Seven Kill Sword Array, add in the Bella Sea Witch's demon bones, and re-forge it. Although this can't increase the grade of the flying swords, it can make them more resilient and less likely to die."

  "Besides, the Seven Killings Sword Array has already taken shape and is a stable combination of yin-yang and the Five Elements. Generally speaking, it's not suitable for modification. However, your innate talent is too strong, and now, through the Great Five Elements Key, the Yin-Yang Mysterious Key, and the No-Form Key as a bridge, you have fully grasped the Tai Xuan Lower Key. The increase in strength is secondary, but what's important is that you can now grasp the balance of yin-yang and the Five Elements very well. In this case, I'll teach you a great array, as well as countless smaller arrays, which can be added to the Seven Killings Sword Array to create the Nine Palaces Split Light Sword Array."

  "The Nine Palaces Splitting Light Sword Formation, nine fourth-grade flying swords?" Zhang Ye's heart began to stir, that would be incredibly powerful.

  "Yes, the power of the Seven Kill Sword Formation itself is almost beyond that of a fifth-grade sword, but it's still inferior to a sixth-grade flying sword. However, if it were the Nine Palace Split Light Sword Formation, after being strengthened by the demon bone, its combat strength would even surpass that of a sixth-grade flying sword."

  The refinement of the sword array is different from that of a simple magic treasure. Since it's not a single entity, it falls under the category of the universe's grand dao, emphasizing harmony and balance. Between heaven and earth, there are only two methods to balance all things: the yin-yang way from top to bottom, and the five elements way from bottom to top.

  Balanced sword array, one must be proficient in at least one of them, otherwise the sword arrays will mutually consume each other.

  Among them, the sword arrays of yin and yang two swords and wu xing five swords are the easiest to see.

  Because it conforms to the two numbers of yin and yang, as well as the five numbers of the five elements, there is no need for the refiner to deliberately balance yin and yang and the five elements. As long as each sword maintains its simple attribute, balance can be achieved.

  But once the number of swords changes, breaking the two instruments and two numbers, five elements and five numbers, it's not something that ordinary people can balance. This requires a very fine division during refinement, almost every sword is a small balance, yin and yang follow each other, and the five elements generate restraint.

  The power of these complex sword arrays is even stronger, and the coordination is more delicate and pure. They are extremely rare because they are difficult to refine, but once they appear on the market, their price is extremely high.

  For example, a four-star flying sword is worth about 6,000 yuan dan on the market. However, once the yin and yang double swords are arrayed, the value of a set will be around 15,000 yuan dan. Calculated by the value of a single sword, it has greatly increased in value, equivalent to 7,500 dan medicine per sword.

  If it's a more difficult Three Talents Formation, then the value of a set of four-rank sword formations would be around 25,000 elixirs, and the value of a single sword would increase again.

  Ordinary people can't refine it, but from bottom to top and from top to bottom, Zhang Ye has mastered the subtleties of yin-yang and the five elements with precision.

  Made a fortune this time.

  Zhang Ye couldn't help but secretly find it amusing...
