"Not bad, during this period of time, You Ruo occasionally came to discuss some issues with Meng Li about the formation method. She has been studying the last few details of the Hunyuan Five Elements Great Formation recently, and I have discussed it with her many times." Yun Mengli leaned against Zhao Di's chest, breathing softly, and said in a gentle voice: "This is the formation that must be used when husband refines his life treasure, so Meng Li also attaches great importance to this old business. After careful consideration, she and You Ruo finally set up this big formation very carefully."

  "Thanks for your hard work, dear wife! However, I don't have any plans to enter the immortal realm at present, and this treasure is not urgent for now." Zhao hugged his beloved wife, looked up at the bright moon, and felt a mix of emotions in his heart.

  "Hehe, husband must also know that Meng Li's time is limited. Over the past decade or so, thanks to husband's companionship, Meng Li has experienced all sorts of unimaginable joys in life, and even if she closes her eyes now, there won't be much regret." Meng Li smiled sweetly, like a blooming flower, without revealing that she was discussing her own mortality. "This formation also contains a part of Meng Li's heart, if husband can use this formation to refine his destined treasure, Meng Li will have fulfilled one of her wishes. I wonder if husband can promise Meng Li that before her lifespan ends, he will refine this treasure and put her heart at ease."

  Zhao Di's eyes welled up with tears, and he remained silent. Although his beloved wife was in good health, the fact that her lifespan was nearing its end was evident to him as a cultivator of the Condensing Dan period. Youlan had cultivated several precious items such as the Ten-Thousand-Year Fire Coral, Ten-Thousand-Year Luminous Glass, and Ten-Thousand-Year Agate Leaf two or three years ago, but he had not started refining them yet. It was not because he was waiting for the Mixed Yuan Five Elements Array to be more perfect, but because he knew his beloved wife's lifespan was limited, and he just wanted to spend more time with her while she was still alive.

  "Alright, I promise you, I'll refine this treasure as soon as possible!" Zhao Di replied softly, controlling his emotions.

  After that, Zhao Di closed the "Listening to Bamboo Book House" temporarily due to physical discomfort and retreated into the underground cave to refine the Hunyuan Seven-Star Sword.

  Youlan and You Ruo had already guessed Zhao Di's intentions when they saw him arrive at the cave with a serious expression.

  They had already prepared a quiet place for Zhao Di to practice his skills, and set up the Mixed Yuan Five Elements Formation here.

  This is the Hunyuan Five Elements Great Array, carefully improved by Yun Mengli and You Ruo, which is formed by arranging twenty-five high-grade spiritual stones of different surnames. The arrangement of these spiritual stones is divided into five groups, each containing one spiritual stone of gold, wood, water, fire, and earth attributes. The Hunyuan Five Elements Great Array takes the shape of a five-petaled plum blossom, with each "petal" inlaid with a group of high-grade spiritual stones. Only after all five groups of spiritual stones are placed can the array's power be activated.

  Each "petal" of this mixed yuan five-element array seems to be a reading power formation, and it is much more complicated than any formation Zhao Di has ever seen. It is full of various symbols and texts, with obscure and incomprehensible inscriptions. Each seemingly rough and random symbol, upon closer inspection, is composed of many small symbols. The entire large formation's five "petals" are interconnected and merged, each symbol having a complex connection with other graphics on the formation, without any isolated imprint.

  Zhao Di walked into the center of the mixed yuan five elements array, sat down with his legs crossed, closed his eyes and cultivated his spirit.

  This time it's been three days and three nights!

  In these three days and nights, he went through every step of the refining process of the Hunyuan Seven Stars Sword, every move, every detail, all perfectly in his mind for three times.

  He had already considered all the details of this specific refining method many years ago, and now he just needed to put these efforts into practice.

  Three days later, Zhao Di, who felt that everything was going smoothly, let out a gentle breath and softly instructed the two girls, You Lan and You Ruo: "It's done!"

  The two women who had been waiting outside the formation immediately came forward and placed a series of precious treasures in front of Zhao.

  Each family name has dozens of high-ranking Ling stones, a fist-sized Tian Gai silver block, a walnut-sized Xuan Feng gold block, Millennium Golden Amber, Millennium Mala Leaf, Millennium Lapis Lazuli, Millennium Fire Coral, and Millennium Agate Stone, as well as over ten types of auxiliary materials that are not in large quantities but all are high-quality.

  Zhao's fingers flew swiftly, and more than twenty high-grade spirit stones rose into the air, inlaid perfectly into the twenty-five array eyes of the Hunyuan Five Elements Great Array. A gentle tap also struck out a spell containing Hunyuan's power, hitting the center of the array below him.

  The law array suddenly emitted dazzling light of five colors: pale gold, cyan, azure, crimson and deep yellow. Along the marks engraved on the formation method, it spread to every symbol and text, and in an instant, the light flowed and the spiritual light flickered. If viewed from above, the mixed yuan five-element array was like a plum blossom that had opened with five-colored spiritual light, magnificent beyond compare, and Zhao Di was sitting right at its center.

  As Zhao Di struck the mixed yuan method into the center of the law array, these five-colored spiritual lights merged with each other, gradually forming a purple light column.

  The purple light pillar grew more and more, slowly devouring the other colored spiritual lights on the formation, gradually, all the spiritual lights activated by the formation turned into purple, without any other colors mixed in. The entire Mixed Yuan Five Elements Formation was like a single branch of five-petaled plum blossoms, casting a purple glow over the entire mountain cave.

  Within the formation, there is no longer any Five Elements spiritual energy; only pure and extreme Primordial Spiritual Energy remains! This Primordial Five Elements Formation perfectly converts the massive Five Elements spiritual energy into Primordial Power, truly flawless!

  "The formation is excellent, no problem at all! Next, I will refine the Seven Treasures of Buddhism. These materials inherently contain a hint of Buddhist power, which can most effectively restrain your sister's ghostly bodies. You two should temporarily retreat for now!" Zhao Di looked at the formation under his feet and smiled at the two women.

  "Yes, master!" The two women retreated and left the cave, but they were worried in their hearts and didn't want to go far, so they stayed at the entrance of the cave.

  Zhao Di grasped a piece of Wan Nian Buo Shi stone, feeling the immense and pure yet surprisingly stable earth-attribute spiritual energy contained within. The corners of his mouth couldn't help but curve upwards slightly in satisfaction.

  In the Seven Treasures of Buddhism, any one of these treasures from a myriad years ago is probably something that even the old monsters from the Yuan Ying period would dream of possessing, its value rivaling that of the Six Roots of Clear Bamboo! Not to mention, he has five of them, making up the Five Elements and Surnames!

  All thanks to the Qian Kun Bao Ding, this Ding can spend several years of time cultivating five treasures such as jade into a year like this, although after that, no matter how long it is cultivated, the spiritual power and age of the treasure have already reached its peak and will not change again. However, this is already the top-grade treasure in Buddhism.

  Although Zhao Di had not practiced Buddhist magic, he could not comprehend the Buddha's power contained in this treasure, but he also clearly felt that the evil energy on his body seemed to be extremely afraid of the piece of Wannian Bixi stone in his hand, and retreated in disarray.

  More than ten years ago, he was forced to use the Burning Soul Secret Technique due to Yun Mengli's coercion, and in a fit of rage, he inadvertently triggered the evil energy around him, ultimately leading to a thread of evil energy invading his heart. He originally wanted to refine the Hunyuan Seven-Star Sword and use it as his life-bound treasure to drive out this thread of evil energy with its contained Buddhist power. However, what he didn't expect was that during these ten-plus years on the island as a teacher, he had been quietly cultivating his surname, and unexpectedly restored quite a bit of the Book's Breath, while that thread of evil energy that invaded his heart seemed to have vanished unknowingly!

  Although Zhao Di no longer needs to rely on the Buddha's power to drive out the evil energy in his heart, from the fact that these seven treasures of Buddhism can make the evil energy retreat, as long as he successfully refines the Hunyuan Seven-Star Sword as his innate treasure, the problem of evil energy that has troubled him for a long time will be fundamentally solved. At least, he won't have to worry about the evil energy entering his body again!

  Apart from this, the Huayuan Qixing sword also carries a thought of his beloved wife, and for Zhao Di, it is extremely significant and absolutely cannot be lost!

  Zhao's smile faded away, and his expression turned serious once again.

  After sitting still for a moment, Zhao Di slightly opened his lips and spat out a purple round pill about the size of an inch, which was exactly the mixed yuan golden elixir condensed by Zhao Di!

  A purple round pill floated above Zhao Di's head, more than three feet high, spinning rapidly and continuously, its speed increasing. Before long, a half-foot-long purple flame shot out from the Hunyuan Golden Pill, which was the Xiantian Dan Fire triggered by the Hunyuan Golden Pill. Due to its continuous rotation, it formed a circular purple sea of fire with a diameter of about one foot.

  Triggering innate dan fire is the most exhausting of spiritual power, and refining equipment is an extremely lengthy process. If one's spiritual power is slightly insufficient during this process, it may result in all previous efforts being wasted, or even the complete destruction and waste of the original materials!

  Zhao Di held in his hands five high-grade spiritual stones, each belonging to a different surname of the Five Elements, slowly absorbing the spiritual energy within and transforming it into his own Primordial Force.

  The purple flames burned more and more fiercely, gradually spreading to over two feet in diameter. The height of the purple flames also reached about a foot. These flames contained extremely great power, but they were neither hot nor cold, and the temperature inside the cave didn't change at all.

  "Rise!" Zhao Di shouted, and the five Buddhist treasures of the Five Elements - Wan Nian Jin Huo and others - flew into the purple sea of fire, spinning and rotating within it, undergoing the burning and refining of the purple flames.

  The next step is to use this innate dan fire to refine these raw materials. However, this process takes an extremely long time.

  After seven days and seven nights of continuous burning in the alchemical fire, the thousand-year-old Liuli Qing first showed signs of melting, with a drop-by-drop impurities dripping out from it, which was quickly turned into ash by the alchemical fire.

  Seven days later, the five pieces of treasure that were originally the size of a fist had been completely melted by the dan fire, and the impurities inside had also been refined clean, turning into five transparent liquid balls of different colors, each about the size of a walnut.

  At this time, Zhao Di was already exhausted from using the true fire of his dantian for a long time. Although he had high-grade spirit stones to replenish his spiritual energy, it was still very strenuous. Fine beads of sweat had seeped out all over his body, and the consumption of his divine sense was also extremely severe. However, he couldn't stop to rest for even a moment because the most critical step in the refining process was about to arrive!
