Those mortal irons with no spirituality were of no use to a top martial artist like Su Han.

On that land, you can see all kinds of treasures full of ancient style, but those treasures have also all decayed, and there is no trace of spirituality.

Su Han shook his head, and under the leadership of Na Mai Fa, he walked towards the interior of the huge castle.

After passing through the corridors and palaces, the two finally came to a spiritual elixir garden in the middle of the huge castle.

"It's gone!!!This time, I'm !!" As soon as Su Han came to the Lingtian, he glanced at the Lingtian, and immediately gasped, and then a touch of ecstasy surged into his heart.

In that incomparably wide, thousand-hectare spiritual field, there was barren and dead silence everywhere, and there were withered spirit grass wrecks everywhere, except for some spirit grasses that could absorb ghost qi, corpse qi, and death qi, there was almost no grass.

In the center of the spiritual field, there is a plant up to fifteen, green and dripping, the aura lingers, overgrown with yellow, orange and orange, engraved with the pattern of heaven and earth, full of aura Sydney spirit tree.

Su Han looked at the strange spirit tree, a flash of excitement flashed in his eyes, and he lost his voice: "Xuanling Treasure Pear Tree." This is the Xuanling Treasure Pear Tree, which is second only to the Ten Divine Trees. It takes 10,000 years to grow one foot, 10,000 years to bloom once, and once to bear fruit once in 10,000 years. The most precious heaven and earth spirit tree. There are so many, there are so many Xuanling Treasure Pears, this time, I have made a fortune! As long as my alchemy cultivation is advanced to the seventh order, I can refine the seventh-order Saint Dan Nie Ling Pill. Made, this time, I made a fortune. ”

The seventh-order Saint Dan Nie Elixir is also the legendary holy medicine of the Nirvana realm. As long as you swallow a Nirvana Pill and refine it, the master of the Nirvana Realm will be able to perform a Nirvana without any side effects and improve a realm.

The reason why this seventh-order Saint Dan Nie Elixir is a legendary elixir is apart from the primeval world. Outside of antiquity, there are basically no births. One of the most important reasons is that the Xuanling Treasure Pear Tree is so rare that it is almost extinct in the Heavenly World.

After Su Han obtained this Xuanling Treasure Pear Tree, as long as he refined enough Nirvana Pill, the strength of the masters under his command would be able to increase by leaps and bounds in the great secret realm of the Nirvana Realm. Get endless benefits.

Moreover, the Xuanling Treasure pear fruit on the Xuanling Treasure Pear Tree is also one of the most precious main medicines and auxiliary medicines for refining the eighth-order and ninth-order holy pills in many legends. It was definitely a great luck for Su Han to be able to obtain this Xuanling Treasure Pear Tree.

"Sure enough, here, there is a large protective array, and it is a large array that is in harmony with nature. If this great array is in its heyday, I can't do anything about it. But now, break it for me!"

After Su Han carefully observed the Xuanling Treasure pear fruit, the corners of his mouth twitched slightly. With a wave of his big hand, one by one the array chess pieces stabbed towards the surroundings of the Xuanling Treasure pear tree.

The array pieces pierced into the defensive array of the Xuanling Treasure Pear Tree, and the spiritual light flashed, and the protective array around the Xuanling Treasure Pear Tree suddenly became dim and collapsed and disappeared.

Su Han stepped into the spiritual field, his body flickered, and he carefully picked the hundreds of catties of Xuanling Treasure pears on the Xuanling Treasure Pear Tree one by one, and put them into jade boxes and sealed them.

Each one of the Xuanling Treasure Pears is very precious. Even a single damage would make Su Han very heartbroken.

After Su Han carefully collected the hundreds of catties of Xuanling Treasure Pears, he urged the mana. He opened the cave dzi and ingested the Xuanling Treasure pear tree into the cave dzi along with the spiritual soil under the tree.

After Su Han received the Xuanling Treasure Pear, his heart moved: "This place is full of dangers, I should be here first and impact the Seventh-Order Alchemy." Refine that Xuanling Treasure Pear into a seventh-order Saint Danne Elixir to improve your strength. And then it will go out of the blue. ”

In this ghost ruins, there are many dangers, and even the masters of the Yuan God Realm will fall in such a fierce place.

After Su Han picked the spirit grass in the elixir garden one by one, he carefully left the elixir garden and returned to a pair of dry bones. One step into the dzi cave.

The dzi shrank and turned into a speck of dust, which fell into the pile of ashes.

As soon as Su Han entered the cave dzi, his spirit condensed, and the wisdom Xuan Wheel appeared, constantly deducing how the seventh-order spirit pill should be refined, and what the medicinal properties of the seventh-order spirit grass were.

In the midst of that continuous deduction, Su Han took out a seventh-order elixir spirit grass, urged the Burning Sun Emperor Fire, and began to refine the seventh-order elixir.

Bang!

Soon, with a loud bang, in the Lingbao-level Ding Furnace, there was a loud noise, and the refining failed, and the furnace exploded directly. Even though Su Han had cultivated the Great Wisdom Sutra, his wisdom was extraordinary, and he had a treasure like the mysterious right eye, it was still difficult to refine the seventh-order spirit pill.

After Su Han took a deep breath, he picked up the wisdom tea on the side and took a sip, and an incomparably mysterious feeling came to his heart, making him calm again, his mind was calm, and his wisdom was also improved.

The tea of wisdom produced on the tree of wisdom is an extremely precious treasure of heaven and earth, and one of the important factors for them to be able to cultivate for a long time is that they can often drink the tea made from the tea of wisdom, which opens their wisdom and improves their understanding.

"Come again!" Su Han's eyes burst with a gleam, and he continued to refine the seventh-order elixir.

Boom! Boom!

With a loud boom, the incomparably precious seventh-order spirit grass of a furnace directly turned into flying ashes. The reason why it was difficult for a seventh-order alchemy grandmaster to appear was because there were too many resources that needed to be consumed.

Su Han cultivated the Great Wisdom Sutra and condensed the Wisdom Xuan Wheel, and his comprehension has surpassed that of the realm king Li Tianxing by many times, and he also has the ability of the mysterious right eye to see through the impurities of the spirit grass and the spirit treasure Ding Furnace, if you want to refine the seventh-order spirit pill, it is still difficult, and if an ordinary alchemy master wants to be promoted to a seventh-order alchemy master, the difficulty can be imagined.

Since the decline of the Little Zihua Realm into the Little Thousand Generations of Lu Realm, the resources have been depleted, and the treasures of heaven and earth have become less and less. Even though the human Dan Dao civilization is developed, there are fewer and fewer seventh-order alchemy masters.

However, within the Six Desires Red Dust Sect, there are many alchemy experiences and alchemy notes of the seventh-order alchemy masters. The experience of those alchemy grandmasters was all cheaper than Su Han.

Su Han was engrossed, completely selfless into alchemy, and the wisdom wheel in his left eye kept rotating, every time he failed. The wisdom of the Xuanlun will record, remember the failure, and constantly improve his alchemy.

Every time Su Han made alchemy, he would gain insights and have a deep understanding of the alchemy techniques of those seventh-order alchemy masters.

On the tenth day, after spending countless heavenly and earthly treasures. Su Han finally broke through the bottleneck and refined the first furnace of the seventh-order spirit pill.

After the first furnace of the seventh-order spirit pill was refined, Su Han's refining of the seventh-order spirit pill could be said to be like a fish in water, and after refining and scrapping the third furnace of the seventh-order spirit pill, it was successful fifteen times in a row.

"It's time to go!"

When Su Han adjusted his state to the best, he flipped his hand and immediately took out a large number of materials for refining the Nirvana Pill, as well as a Xuanling Treasure Pear.

The spirit grass that refined the Nirvana Pill was all sixth-order and seventh-order spirit grasses that were rare in the outside world, as well as some precious demon beast essence blood. If ordinary people want to collect so many materials. It's simply impossible.

However, Su Han extinguished the Six Desires Red Dust Sect and received the treasure house of the Six Desires Red Dust Sect, and there were countless kinds of incomparably precious spirit grasses, and he easily collected the materials for refining the Nirvana Pill.

Su Han took a deep breath, looked at the pile of Nirvana Pill materials, flicked his fingers, and a mana surged, and rolled up the pile of materials along with the Xuanling Treasure Pear. Flew into the four elephants.

A Blazing Sun Emperor Fire sank into the Four Elephant Ding, and the Four Elephant Ding immediately spewed out countless flames and enveloped the pile of materials. Traces of black smoke rose up.

Three hours later, all the materials within the four elephant tripods were completely purified, forming a mass of spiritual liquid.

Su Han punched into one after another mysterious pill tricks and submerged into the mass of spiritual liquid.

Only then did the mass of spiritual liquid begin to fuse in a certain order according to the medicinal properties.

It took three hours for the mass of spiritual fluid to slowly fuse and finally condense into shape.

When that mass of spiritual fluid is completely fused. Su Han shot out one ancient pill after another, and submerged into the ball of spiritual liquid.

The ball of spiritual fluid suddenly divided, and twenty-four balls of spiritual fluid the size of thumbs were separated at once, and they continued to rotate.

In the end, under the spiritual fire gushing out of the four elephant tripods, the twenty-four balls of spiritual liquid the size of thumbs condensed and formed, forming twenty-four fragrant and attractive pieces. The orange-red peerless Saint Dan.

As soon as the twenty-four holy pills were formed, Su Han breathed a sigh of relief, the wisdom Xuancha in his left eye, and the mysterious rune in his right eye suddenly dissipated, and with a flick of his fingers, the lid of the four elephant tripods flew up immediately, and a strange fragrance shrouded the entire cave dzi.

Su Han looked at the twenty-four Nirvana Pills that were full of strange fragrance and brilliance, and a flash of excitement flashed in his eyes: "Twenty-four Nirvana Pills! Great, with the materials I currently have in my hands, I can also refine the Five Furnaces Nirvana Pill." In this way, I will have a total of one hundred and twenty Nirvana Pills!!! It is enough for me to cultivate several more peerless masters of the Nirvana Realm Nine Heavens. ”

The Nie Spirit Pill is a saint-level pill among the seventh-order spirit pills, except for the Xuanling Treasure Pear, the rest of the materials are also extremely precious, the spirit grass spirit fruit that is difficult to find in the world, Su Han scraped the treasure house of the Six Desires Red Dust Sect, as well as the treasure house of several martial arts holy places, and the spirit grass obtained can only refine the peerless holy pill like the Five Furnaces. That's why it's hard to be born with a top Saint Dan.

Each top-notch Saint Pill requires a large amount of incomparably precious spirit grass to be able to refine it, and no less material is enough. Only the great sects have the strength and heritage, and they have collected countless precious materials and refined them. Ordinary casual cultivators are already very lucky to be able to get a single material, and it is almost impossible to collect all the precious materials.

Su Han sat down cross-legged, twisted a nirvana pill with three fingers and swallowed it into his abdomen.

As soon as the Nirvana Pill sank into Su Han's abdomen, it immediately turned into an incomparably pure spiritual power and submerged into his limbs and hundreds of remains, endlessly, like a source of spiritual power.

Su Han immediately urged the Great Five Elements Zhen Tiangong, and the five dantians in his body were like a huge whirlpool, sweeping towards the Nirvana Pill, frantically devouring the Nirvana Pill.

"Not enough!" Su Han suddenly opened his eyes, picked up two Nirvana pills again, and swallowed them into his stomach in one gulp.

As soon as those two Nirvana Pills were swallowed into Su Han's abdomen, they immediately turned into two incomparably pure spiritual power sources and released incomparably pure spiritual power, which submerged into his body and was frantically refined by his Great Five Elements Zhentian Gong.

Three days later, Su Han's flesh and blood began to crumble, and his internal organs flew out, and the void floated.

Su Han swallowed a large amount of Nirvana Pill at once, and the slightest trace of Nirvana Qi enveloped his whole body, and he struggled to break the laws of heaven and earth into the five internal organs, and began to carry out Nirvana.

With the support of that large number of Nirvana Pills, Su Han finally completed a Nirvana very smoothly and was promoted to become a martial artist of the Seven Heavens of the Nirvana Realm.

After swallowing the elixir and nirvana, Su Han hid in the cave dzi and continued to cultivate and improve his strength.

Time passed, and two months later, in the ancient castle full of ashes, Su Han immediately appeared in the ancient castle, and a powerful and complete aura spread out from his body.

A flash of excitement flashed in Su Han's eyes, and a powerful self-confidence permeated from his body: "Finally promoted to the Nirvana Realm Nine Heavens, this time I was promoted, I actually consumed fifty-six Nirvana Pills, this kind of consumption is really terrifying." ”

Ordinary martial artists only need one pill of Nirvana Pill to advance in the Nirvana Realm at a time, but Su Han was promoted from the Sixth Heaven of the Nirvana Realm to the Ninth Heaven of the Nirvana Realm, and in just three Nirvana, he spent fifty-six pills of the Saint-level Elixir such as the Nirvana Pill, which was extremely terrifying. However, after being promoted to the Nirvana Realm Nine Heavens, Su Han's strength was also extremely strong.

A strange glint flashed in Su Han's eyes, revealing a confident smile: "Now I am sure that I will be able to escape from this ghost ruin." And you can also explore this ghost ruin. ”

"Congratulations to the master, congratulations to the master for his promotion to become a peerless powerhouse of the Nine Heavens of the Nirvana Realm. The Rat King Mai Fa suddenly ran out of a corner and smiled flatteringly at Su Han.

The martial artists of the Nine Heavens of the Nirvana Realm are almost invincible in this small Zihua Realm, and only the powerhouses of the Yuan Shen Realm can compete with them, and they can truly be called peerless powerhouses.

Su Han smiled and asked at the Rat King Mai, "Is there any other place around here that has good treasures?"

Su Han left the Rat King Mai Fa here, so that he could manipulate the huge swarm of rats to explore various places in this ancient city, specializing in treasure hunting.

"This is the various spirit grasses that Xiao has found here in the past few months. The Rat King Mai Fa obediently handed a storage ring to Su Han, and then pointed to the depths of the ancient castle: "Master, there is a black coffin across that direction, and there should be a flying corpse king in that black coffin."
