Those mortal irons with no spirituality are of no use to top warriors like Su Han. On that land, you can see all kinds of ancient-style treasures everywhere, but those treasures are also all decayed and have no trace of spirituality. Su Han shook his head and, under the leadership of Na Maifa, walked towards the interior of the huge castle. After passing through many corridors and palaces, the two finally came to a spiritual medicine garden in the huge castle. "It's successful! This time, I'm prosperous!!!" As soon as Su Han came to the spiritual field, he took a look at the spiritual field, and immediately took a breath of air, and then a touch of ecstasy came to his heart. In that extremely wide spiritual field, which is thousands of hectares high, everything is deserted and dead, and there are withered remains of spiritual grass everywhere. Except for some spiritual grass that can absorb ghost energy, corpse energy, and death energy, almost no grass grows. In the center of the spiritual field, there grows a pear tree that is as tall as fifteen, green and green, full of spiritual energy, covered with yellow and orange trees, engraved with the patterns of heaven and earth, and full of spiritual energy. Su Han looked at the strange spiritual tree, and a flash of excitement flashed in his eyes, and he lost his voice and said: "Xuanling Baoli Tree. This is the Xuanling Baoli Tree, second only to the top ten sacred trees. It only grows once in ten thousand years. It blooms once every ten thousand years and bears fruit once every ten thousand years. There are so many Xuanling Baoli, so I am rich! After I advance to the seventh level of alchemy, I can refine the seventh-level holy elixir of nirvana. This time, I am rich. " The seventh-level holy elixir of nirvana is also the holy medicine of the nirvana realm. As long as a nirvana pill is swallowed and refined, a nirvana master can perform nirvana without any side effects and advance to a higher level. The reason why this seventh-level Saint Dane Elixir is a legendary holy medicine is that it is ancient. Outside of ancient times, basically no one was born. One of the most important reasons is that the Xuanling Baoli tree is so rare that it is almost extinct in the world of heaven. After Su Han gets this Xuanling Baoli tree, as long as he refines enough Nirvana Pills, his masters will be able to advance by leaps and bounds in the great secret realm of Nirvana Realm. Get endless benefits. And the Xuanling Baoli fruit produced on the Xuanling Baoli tree is also one of the most precious main medicines and auxiliary medicines for refining many legendary eighth-level and ninth-level holy elixirs. Su Han was definitely very lucky to be able to obtain this Xuanling Baoli tree. "Sure enough, there is a protective formation here, and it is also a great formation that is in harmony with nature. If this formation were at its peak, I would not be able to do anything about it. But now, break it for me!" Su Han carefully said After observing the Xuanling Baoli Fruit, the corners of his mouth twitched slightly. With a wave of his hand, the chess pieces stabbed around the Xuanling Baoli tree. The chess pieces pierced into the defensive formation of the Xuanling Baoli tree. The spiritual light flashed, and the protective formation around the Xuanling Baoli tree suddenly became dim, collapsed and disappeared. Su Han stepped into the spiritual field, his body flashed, and he carefully picked the hundreds of kilograms of Xuanling Baoli that were full of Xuanling Baoli trees one by one, and put them in They were sealed in jade boxes one by one. Every piece of Xuanling Baoli is very precious. Even if one of them is damaged, Su Han will be very heartbroken. After Su Han carefully collected the hundreds of kilograms of Xuanling Baoli, he activated his magic power. He opened the Cave Dzi Bead and absorbed the Xuanling Baoli tree and the spiritual soil under the tree into the Cave Dzi Bead. After Su Han collected the Xuanling Baoli, he thought: "This place is full of dangers. I should attack the seventh-level alchemy technique here first. Refining the Xuanling Baoli into the seventh-level Holy Elixir Pill, Improve your own strength. Then go out. "There are many dangers in this ghost ruins. Even masters in the Yuan Shen realm will fall in such a dangerous place. After Su Han picked the spiritual herbs in the elixir garden one by one, he carefully left the elixir garden and returned to a pair of withered bones. Stepping into the Cave Dzi Bead. The Cave Dzi Bead shrank and turned into a speck of dust, falling into the pile of ashes. As soon as Su Han entered the Cave Dzi Bead, his spirit condensed, and the Mysterious Wheel of Wisdom appeared. He continued to deduce how the seventh-level spiritual elixir should be refined, and what the medicinal properties of the seventh-level spiritual grass were. During the continuous deduction, Su Han took out a portion of the seventh-level spiritual elixir, activated the Lieyang Emperor Fire, and began to refine the seventh-level elixir. Boom! Soon, there was a loud noise in the Lingbao-level cauldron. The refining failed and the furnace exploded. Even though Su Han has practiced the Great Wisdom Sutra, has extraordinary wisdom, and possesses treasures like the mysterious right eye, it is still difficult to refine the seventh-level elixir. After Su Han took a deep breath, he picked up the tea of ??wisdom on the side and took a sip. A mysterious feeling came to his heart, which made him regain his calm, his mind was peaceful, and his wisdom also improved a little. The Tea of ??Wisdom produced on the Tree of Wisdom is an extremely precious treasure of heaven and earth. One of the important factors for Ming Shuixiang and the others to be able to practice thousands of miles is that they can often drink the tea brewed from the Tea of ??Wisdom. Their wisdom improves their understanding. "Come again!" Su Han's eyes flashed with light and he continued to refine the seventh-level elixir. Boom! Boom! With a loud rumbling sound, furnaces of extremely precious seventh-level spiritual grass turned directly into fly ash. The reason why it is difficult for a seventh-level alchemy master to appear is because too many resources need to be consumed. Su Han practiced the Great Wisdom Sutra and condensed the Mysterious Wheel of Wisdom. His understanding has surpassed the realm king Li Tianxing countless times, and he also has the power of the mysterious right eye that can see through impurities in spiritual grass and spiritual treasure cauldrons. Making seventh-level elixirs is still very difficult. One can imagine the difficulties faced by ordinary alchemy masters who want to be promoted to seventh-level alchemy masters. Since the Little Purple Flower Realm declined and became the Little Thousand World, resources have been depleted and the treasures of heaven and earth have become less and less. Even though human alchemy civilization has developed, there are fewer and fewer seventh-level alchemy masters. However, within the Six Desires of Red Dust Sect, there are many alchemy experiences and alchemy notes of seventh-level alchemy masters. The experience of those alchemy masters all came to Su Han's advantage. Su Han concentrated his energy and devoted himself completely to alchemy. The wisdom wheel in his left eye kept spinning, failing every time. The Mysterious Wheel of Wisdom will record and keep that failure in mind, and continue to improve his alchemy skills. Every time Su Han made alchemy, he would gain insights and have a deep understanding of the alchemy skills of those seventh-level alchemy masters. On the tenth day, after spending countless resources from heaven and earth. Su Han finally broke through the bottleneck and refined the first batch of seventh-level elixir. After refining the seventh-level elixir in the first furnace, Su Han was able to refine the seventh-level elixir like a fish in water. After refining the seventh-level elixir in three furnaces, he succeeded fifteen times in a row. "It's time to start!" When Su Han adjusted his condition to the best, he turned his hand and immediately took out a large amount of materials for refining the Nirvana Pill, as well as a Xuanling Baoli. The spiritual herbs used to refine the Nirvana Pill are all sixth- and seventh-level spiritual herbs that are rarely seen in the outside world, as well as some precious monster blood essences. If ordinary people want to collect so much material. Totally impossible. " However, Su Han destroyed the Liuyu Hongchen Sect and took over the Liuyu Hongchen Sect's treasure house. There were countless precious spiritual herbs, and he easily collected the materials to refine the Nirvana Pill. Su Han took a deep breath, looked at the pile of materials for the Nirvana Pill, flicked his fingers, and a surge of mana quickly rolled up the pile of materials together with the Xuanling Baoli. He flew into the Four Elephants Cauldron. A blazing Sun Emperor Fire submerged into the Four-Elephant Cauldron, which immediately spewed out countless flames and enveloped the pile of materials. Threads of black smoke rose. Three hours later, all the materials in the Four Symbols Cauldron were completely purified, forming masses of spiritual liquid. Su Han penetrated a series of extremely mysterious elixir techniques and submerged them into the globs of spiritual liquid. The clumps of spiritual liquid began to fuse in a certain order according to the properties of the medicine. It took a full three hours for the clumps of spiritual liquid to slowly merge and finally condense into shape. When the masses of spiritual liquid are completely integrated. Su Han shot out ancient elixirs one after another and submerged them into the spiritual liquid. The group of spiritual liquid suddenly divided into twenty-four thumb-sized groups of spiritual liquid, which were constantly rotating. Finally, under the burning spiritual fire that spewed out from the four elephant cauldron, the twenty-four thumb-sized groups of spiritual liquid condensed and formed, forming twenty-four fragrant and attractive stones. The orange-red peerless holy elixir. As soon as the twenty-four holy pills were formed, Su Han breathed a sigh of relief. The mysterious wheel of wisdom in his left eye and the mysterious rune in his right eye immediately dissipated. With a flick of his finger, the lid of the four-symbol tripod suddenly disappeared. Flying up, a strange fragrance enveloped the entire cave dzi bead. Su Han looked at the twenty-four Nirvana Pills that were full of fragrance and radiant, with a flash of excitement in his eyes: "Twenty-four Nirvana Pills! That's great. With the materials I currently have in hand, it's okay. After refining five furnaces of Nirvana Pills, I will have a total of one hundred and twenty Nirvana Spirit Pills! That¡¯s enough for me to train several more peerless masters in the Ninth Level of Nirvana.¡± That number is seven. Except for the Xuanling Baoli, the other holy-level elixirs in the Grade Spiritual Pill are all extremely precious. Spiritual herbs and fruits that are hard to find in the world, Su Han scraped away the six desires of the mortal world.The spiritual grass obtained from the treasury of the Sect and several martial arts holy places can only be used to refine five furnaces of such peerless holy elixirs. This is the reason why it is difficult for the top holy elixir to be born. Every top holy elixir requires a large amount of extremely precious spiritual grass to be refined, and even one less material will not work. Only large sects have the strength and foundation to collect countless precious materials and refine them. Ordinary casual cultivators are very lucky to be able to get even one material. It is almost impossible to collect all the precious materials. Su Han sat down cross-legged, picked up a Nirvana Pill with three fingers and swallowed it in one gulp. As soon as the Nirvana Pill sank into Su Han's belly, it immediately turned into a stream of extremely pure spiritual power and penetrated into his limbs and bones. It continued to flow, endlessly, like a source of spiritual power. Su Han activated the Great Five Elements Heaven-Suppressing Technique at once, and the five Dantians in his body were like a huge whirlpool, sweeping towards the Nirvana Pill and devouring the Nirvana Pill crazily. "Not enough!" Su Han suddenly opened his eyes, picked up two Nirvana Pills again and swallowed them in one gulp. As soon as the two Nirvana Pills were swallowed by Su Han, they immediately turned into two sources of extremely pure spiritual power and released the extremely pure spiritual power. They entered his body and were crazily refined by his Great Five Elements Heaven-Suppressing Technique. change. Three days later, Su Han's flesh and blood began to crack, his internal organs flew out, and he floated in the void. Su Han swallowed a large amount of Nirvana Pill at once, and the air of Nirvana enveloped his whole body. It was very difficult to penetrate the laws of heaven and earth into the internal organs, and began to carry out Nirvana. With the support of a large amount of Nirvana Pills, Su Han finally completed Nirvana very smoothly and was promoted to a warrior in the seventh heaven of Nirvana. After swallowing the elixir and attaining nirvana, Su Han hid in the Dzi Bead and continued to practice hard to improve his strength. Time passed, and two months later, in the ancient castle filled with ashes, Su Han suddenly appeared in the ancient castle with a flash of inspiration, and a powerful and perfect breath came from his body. spread out. A flash of excitement flashed in Su Han's eyes, and a strong self-confidence spread out from his body: "I have finally been promoted to the ninth level of Nirvana. This time, I consumed fifty-six Nirvana Pills. This kind of consumption is really Horrible. "Ordinary warriors only need one Nirvana Pill to advance to the Nirvana Realm, but Su Han spent fifty-six Nirvana Pills to advance from the Sixth Heaven of Nirvana Realm to the Nirvana Realm of Nirvana. Such a holy level elixir is extremely consuming. However, after being promoted to the Ninth Level of Nirvana, Su Han's strength became extremely powerful. A strange light flashed in Su Han's eyes, and he showed a confident smile: "Now I am confident that I can escape from this ghost ruins. And I can also explore this ghost ruins." "Congratulations, master, congratulations The master has been promoted to a peerless expert in the Ninth Level of Nirvana." Mouse King Maifa suddenly ran out from a corner and smiled flatteringly at Su Han. Warriors in the Ninth Level of Nirvana Realm are almost invincible in this Little Purple Flower Realm. Only the strong ones in the Yuan Shen Realm can compete with them and can truly be called peerless experts. Su Han smiled and asked Rat King Maifa: "Is there any good treasure anywhere near here?" Su Han left Rat King Maifa here so that he could control the huge group of rats and explore the ancient city. Every place is dedicated to treasure hunting. "These are the various spiritual herbs that I have found here in the past few months." Mouse King Maifa obediently handed a storage ring to Su Han, then pointed towards the depths of the ancient castle and said: "Master, where is There is a black coffin across the way, and there should be a Flying Corpse King inside that black coffin."
