Chang Shan opened his eyes, glanced around, pondered for a moment, and walked out of the stone room. When he arrived at Tianchengzong's house, he sensed Luo Yongchuan's breath in the house.

"The remaining star power in the star array should be enough for you to condense a pattern, Chang Mou took his leave. ”

After passing on the voice to Luo Yong, Chang Shan thought about it, took out a storage bag, put three hundred spirit stones in it, threw it at the door, and then moved and disappeared in place.

Chang Shan left the big mountain where Tiancheng Sect was located, and traveled about 800 miles to the west, and came to a big mountain full of red maple trees.

Even though there are no maple leaves on the red maple tree at this time, the bark of the red maple tree is also red, and from a distance, the entire mountain looks like it is overgrown with red flowers.

"Red Flower Mountain!"

Chang Shan stared at the mountain in front of him and pondered for a moment, then continued westward along Honghua Mountain.

Although Chang Shan didn't have the heart to go to Red Flower City to have a look, now that he had encountered Red Flower Mountain on his way to find a place to cross the tribulation, he had no reason to avoid it.

When night fell, Changshan came to Honghua City, which is located in the northwest of Honghua Mountain.

The area of Red Flower City was not smaller than that of Martial City, however, the proportion of cultivators in the city was far inferior to that of Martial City.

After resting in a restaurant for the night, early the next morning, Chang Shan followed the route told by the shopkeeper to the Honghuatang located in the center of Honghua City.

Honghuatang is the property of the Red Cloud Dan Sect, and the main thing to buy in it is, of course, the pills. There is never a shortage of customers in the pill shop, but early in the morning, there is only one guest in Changshan in the entire Honghua Hall.

Unlike the shops that Chang Shan had been to before, the shelves in the Red Flower Hall were all placed behind the counters, and if you wanted to see any pills, you had to ask those guys.

Chang Shan glanced at a few guys and walked up to a guy in his thirties.

Without waiting for Chang Shan to speak, the guy asked first, "What elixir does the senior want?"

"If it's convenient, show me the names of the pills in your store. ”

Chang Shan just wanted to buy some pills for self-defense, but he didn't particularly need a certain pill, so he wanted to see what pills Honghuatang had.

The guy froze for a moment and pulled out a booklet from the storage bag around his waist.

The booklet is not thick, only ten pages, the first nine pages contain the names of one hundred and eighty-two pills, but the last page does not contain the names of the pills.

"It is worthy of the store opened by the Dan Sect, and there are one hundred and eighty-two kinds of pills stored. ”

Thinking about it, Chang Shan pointed to the last page and asked the guy, "This spark talisman is used to release the fire of the stars?"

Among the power of the five elements, the power of the fire attribute is divided into various flames according to their different natures, and the fire of the stars refers to those flames that have a purifying effect, and this flame can be used to quench out the impurities of minerals.

"Not bad!"

"Can the spark released by this spark talisman expel the impurities in this piece of Yin Iron Essence?"

The guy glanced at the Yin Iron Essence that Chang Shan took out, and arched his hand: "Senior, please wait a minute, junior please ask the shopkeeper to come out and explain to you." ”

"Thank you!"

When the guy left, Chang Shan was fine, and he looked through the pamphlet again.

After a while, the man who left came to Changshan with a middle-aged woman in blue with a face in her forties.

The guys in the shop, except for the one who entertained Chang Shan just now who was in the middle stage of the Red Pill, the other three did not form the Yuan Dan, but this middle-aged woman was a cultivator in the late stage of the Orange Pill.

The middle-aged woman nodded lightly at Chang Shan, greeted her, and said with a smile, "Daoyou, can you let me take a closer look at that piece of Yin Iron Essence?"

"Good!"

Chang Shan answered and put the Yin Iron Essence on the counter.

The middle-aged woman picked up the Yin Iron Essence and observed it carefully for a while, put the Yin Iron Essence on the counter, looked at Chang Shan and said, "If you want to expel the impurities in this Yin Iron Essence, you need at least three Spark Talismans." ”

"Three?"

Chang Shan frowned slightly, and asked, "How many spirit stones does a Starfire Talisman cost?"

"One hundred!"

Without the fire of the stars, Chang Shan spent a little time, and he could use his own true fire to expel the impurities in the Yin Iron Essence, and use three hundred spirit stones to drive away the impurities in the Yin Iron Essence in Chang Shan's hand, only a fool would do this.

In fact, Chang Shan didn't want to buy the Spark Talisman to get rid of the impurities in the Yin Iron Essence in his hand.

After pondering for a moment, Chang Shan looked at the middle-aged woman and asked, "If you ask for more at a time, can Daoyou be cheaper?"

The middle-aged woman smiled slightly and asked, "How many do you want?"

Chang Shan thought for a moment and replied, "Thirty!"

"Thirty?"

The look of astonishment flashed on her face, and the middle-aged woman smiled bitterly: "There are only eighteen spark talismans in the Red Flower Hall!"

After a slight pause, the middle-aged woman continued: "If there are too many materials that Daoist friends need to refine, it is better to buy a set of Tiangang Spark Array Flags. ”

"Tiangang Starfire Array, this formation can condense the aura into a star fire?"

"That's right! The stellar fire condensed by the Tiangang Spark Array is not as pure as the stellar fire contained in the Spark Talisman, but it is better than an endless stream, and it is most suitable for driving out impurities in various minerals. ”

Chang Shan nodded, pondered for a moment, and asked, "How many spirit stones do you need for a set of Tiangang Spark Array Flags?"

"Sixty-eight thousand!"

Chang Shan's face changed slightly, and he continued: "A set of top-grade spirit arrays is only a few thousand spirit stones, isn't this Tiangang Xinghuo array an immortal array?"

The middle-aged woman shook her head and said with a smile: "The Tiangang Starfire Array is not even a mid-grade Spirit Array, but rare things are precious, and in the entire Da'an Dynasty, even including the adjacent Dayu Dynasty, Tianping Dynasty, and Lingxi Dynasty, only the Hongyun Dan Sect has the Tiangang Starfire Array that can condense the fire of the stars. Sixty-eight thousand spirit stones to buy a formation that can condense the fire of the stars, and you will definitely not suffer a loss. ”

Chang Shan frowned and pondered for a moment, then said in a deep voice, "Can Daoyou take out the Tiangang Starfire Array for me to see?"

"I don't have the Tiangang Spark Array on my body, if the Daoist friend really wants it, I will go back to the Red Cloud Dan Sect to get it for you now. ”

"As long as the Tiangang Starfire Array can really condense the Starfire, I definitely want it. However, I don't have enough spirit stones on me, so I need to go back to my master to ask for them. ”

The middle-aged woman nodded and said with a smile: "It will take an hour for me to go back to the Red Cloud Dan Sect, Daoist friends go to the backyard and wait!"

"Good!"

Chang Shan waited in a small courtyard in the backyard for an hour and a half before the middle-aged woman returned.

After a few polite sentences with Chang Shan, the middle-aged woman took out a jade box with a length and a half feet and a half width from the storage ring and handed it to Chang Shan.

Chang Shan took the jade box and opened it to take a look, and saw six rows of array flags inside. Each row of array flags has six poles, and the six rows of array flags are exactly the number of Tiangang.

"Can I lay out the formation and take a look?"

"Please!"

Chang Shan thanked him, evenly inserted the thirty-six array flags into a circle, and then poured a true element into the thirty-six array flags in a moment.

The red light of the thirty-six array flags flashed, and the place surrounded by the thirty-six array flags was instantly filled with fire attribute aura, and after a while, a light red flame appeared in the center of the thirty-six array flags.

Chang Shan felt the breath of the pale red flame intently, took out a pale yellow silkworm cocoon, and controlled it to move above the pale red flame with the true yuan.

After the pale yellow cocoon was calcined by the pale red flame for half an hour, the whole cocoon became a little smaller, but the color of the cocoon was a little brighter.

Chang Shan put the silkworm cocoon into the storage ring, withdrew the Tiangang Spark Array, pondered for a moment, and said to the middle-aged woman: "Fellow Daoist, can this formation be cheaper?"

The middle-aged woman shook her head and replied: "Daoist friends are also formation cultivators, and if you think about it, you should understand that the formation flags of some formations require special silk to refine, and the Tiangang Xinghuo Array is such a formation. Due to the lack of materials, every eighteen years, the sect can refine a set of Tiangang Spark Array Banners. A set of Tiangang Spark Array Banner 68,000 spirit stones is already very cheap. ”

Chang Shan frowned and hesitated, took out the ten thousand spirit plates and the high-grade spirit sword he got from Wang Feng, and said in a deep voice: "This ten thousand spirit is counted as eighteen thousand spirit stones, this flying sword is counted as six thousand spirit stones, and I will give you another forty-four thousand spirit stones, how about it?"

The middle-aged woman took the Ten Thousand Soul Disk and the Flying Sword and probed it, pondered for a while, nodded, and said in a deep voice: "Okay!"

After the transaction, Chang Shan left the Red Flower Hall and left the Red Flower City directly.

Chang Shan always likes to beg for caution, sixty-eight thousand spirit stones is not a small amount, therefore, before the transaction, he made the well-informed Honghuatang shopkeeper think that there was a not simple master behind him, and then he didn't dare to play any tricks through the hints of words and the silk used to refine the array flag, and the extremely skilled array technique.

After the transaction was over, Chang Shan was too lazy to install it again, so he stayed away from Honghua City and Honghua Mountain as quickly as possible.

Chang Shan had originally planned to survive the Heavenly Tribulation and return to the Daewoo Dynasty, but now he planned to go to a place in the Daewoo Dynasty that he had been to before.

After traveling for seventeen days in a row, Chang Shan walked to the stone mountain where he was going to cross the catastrophe.

After arriving at the stone mountain, Changshan felt the richness of the aura and came to a valley with some bushes.

Walking to the end of the valley, Changshan found a stone cave for only one person to enter and exit.

Feeling that there was a relatively strong fire attribute aura in the stone cave, Chang Shan hesitated for a moment and walked into the cave. The cave is crooked, and it is more than 1,000 zhang deep.

After walking deeper for more than seven hundred zhang, Chang Shan suddenly felt that the air around him was filled with some pungent smells.

Chang Shan pondered for a moment, his heart moved, and he said secretly: "No wonder the fire attribute aura on this stone mountain is obviously stronger, it turns out that there is a volcano under this stone mountain." ”

Without the intention of going to the volcano to hunt for treasure, Chang Shan retreated more than ten zhang and turned into a stone cave seven or eight zhang long.

Chang Shan dug a stone chamber at the end of the stone cave and cultivated it carefully.

In fact, a cultivator also needs to have some understanding of the mysteries of heaven and earth to improve his cultivation, but generally speaking, as long as there are three dao patterns on a cultivator's Yuan Dan, his level of comprehension of the mysteries of heaven and earth is enough to raise his cultivation to the Great Perfection realm of a realm.

Chang Shan has nine Dao patterns above the Yuan Dan, and his perception of the mysteries of heaven and earth is certainly enough for him to raise his cultivation to the realm of the Great Perfection of the Orange Dan stage.
