The sole purpose of Guo Yang's retreat was to refine the chaotic yin and yang qi in his body into one to form the power of chaos.

This is also the most basic and difficult step of "Innate Mixed Yuan Gong".

Originally, if Guo Yang had been able to get the guidance of a master or if he could fully comprehend the essence of his exercises and cultivate step by step when he first began to cultivate, the two qi of yin and yang in his body would have been easily refined and integrated into one.

However, when Guo Yang got the "Congenital Mixed Yuan Gong", he was still a nine-year-old sheep herding baby, and he didn't know a single big character, so how could he comprehend it! If he hadn't swallowed the pills in two small bottles by mistake, where would he still have today's cultivation achievements, he might have been trapped in that deep pit a long time ago.

However, before the retreat, Guo Yang secretly arranged an exchange meeting through the channel of the Immortal Hall.

Guo Yang quietly came to the exchange meeting and walked around the stalls quietly.

His first goal was a set of formation flags.

He has been busy with cultivation, although he also knows a lot about formations, but since he has seen Leng Ruyan's formation attainments, Guo Yang is determined to strengthen his ability in this area in the future.

However, before the knot, Guo Yang didn't want to spend too much time studying the formation. But I don't mind paying a lot of money to buy a few sets of powerful formations.

He had also paid close attention to the magic weapons in the formation in Fang City, but he had never encountered a satisfactory one. And at this exchange meeting, in front of a Xuanyin Sect Jindan senior, there was a set, and it seemed that the grade was not low.

Guo Yang pretended to walk over casually, picked up the set of array flags, and asked, "Uncle Shi, what is the name of this set of array flags?"

"The day after tomorrow, the Seven Tribulation Array. The senior of the Jindan stage said lightly.

"The day after tomorrow, the Seven Tribulation Array, please Uncle Teacher, what is this set of array flags mainly used for?" Guo Yang really didn't understand this time, so he honestly asked.

"You're from the Immortal Hall? The senior of the Jindan period glanced at Guo Yang and said.

"The junior Guo Xiaohu is from the Immortal Hall. Guo Yang hurriedly replied.

"You ascend and descend inside and outside the Hall of Eternal Life, but you have all made us miserable. The senior of the Jindan period said expressionlessly.

Guo Yang hurriedly arched his hand and said: "The predecessors really wronged their subordinates, such a major matter, which can be decided by me in such a small foundation building period, and the subordinates are just acting on the instructions of the left envoy." ”

"You want this flag?" The senior of the Jindan period listened to Guo Yang put all the responsibility on the left envoy, his face froze, and he asked instead.

"Exactly. Over the years, his subordinates have always wanted to learn the art of formation, but they have no time to learn systematically, which is a pity. So I want to buy a set directly in case I need it. Guo Yang said.

"Yes, it should be. If you don't reach the Jindan stage, you should have focused on cultivation. The senior of the Jindan period said indifferently.

"Uncle Teacher, how to use this set of array flags?" Guo Yang asked.

"This set of array flags is mainly to trap the enemy, and it contains seven tribulations, seven difficulties and seven illusions. Among them, seven calamities are sad, seven are sad, and seven illusory are sad. If there is one, it is all injured. Because it is an acquired refining, it is comparable to an innate magic weapon, so it is called the Seven Tribulation Array of the Day After Tomorrow. The senior of the Jindan period said coldly, quite proud of his formation flag.

"Can this formation trap a high-level beast demon?" asked Guo Yang.

"If the Jindan stage cultivator doesn't check into the formation, he will have to shed a layer of skin if he doesn't die, not to mention the beast demons!" said the Jindan stage senior proudly.

"This array of flags is so powerful, I just don't know what Uncle Shi wants to exchange for?" Guo Yang finally asked the point.

"The best materials, or any twelve kinds of elixirs needed to refine the Pei Ying Pill. The senior of the Jindan period said.

Guo Yang took a breath of cool air, his face was embarrassed, and said: "I definitely don't have the best materials for a foundation building period, and I have some elixirs for Peiying Dan, but it seems that there are not enough for twelve." ”

"That's sorry. The senior of the Jindan period said lightly.

"Uncle Shi, see if you can convert it into a spirit stone...... Guo Yang asked with a bitter face.

"No, I can't. Before Guo Yang could finish speaking, the Jindan seniors refused.

"Well, that can't be helped. Guo Yang walked away step by step.

After finding a place where no one was paying attention, Guo Yang took out a porcelain bottle from the storage bag, quietly poured out a pill from it, and put it into another empty bottle, and then walked back as if nothing happened.

"Uncle Shi, this set of array flags ......" Guo Yang was just about to speak, when the corner of his eyes flicked, but he saw that the set of array flags was gone.

The senior of the Jindan period said lightly: "It has been exchanged for a Peiying Pill." ”

Guo Yang was bitter in his heart, but said indifferently on his face: "It seems that the blessings of his subordinates are not deep enough." ”

Guo Yang turned around and left, muttering in his mouth: "It seems that the best Peiying Pill can only be kept for himself and used later." ”

"Wait, what are you talking about?" The face of the senior in the Jindan stage changed sharply, and he asked directly.

Guo Yang looked left and right vigilantly, and said in the same voice: "Once, the junior was chased by a fifth-order beast demon, and finally escaped to a valley, only to encounter two Jindan stage masters fighting the method, one of them was seriously injured and died, and the other was also dying. I happened to run into it, and I was supposed to save someone, but as soon as I ran over, I was smashed by that person. When I woke up and found that the Jindan monk was also dead, I took the things from him. ”

Guo Yang's face was embarrassed, and he seemed to be quite embarrassed about taking the sheep by the hand.

He continued: "Back in the cave, I opened it and saw that there were more than a dozen high-grade elixirs and one elixir inside. I don't know what this is Pei Ying Dan. ”

The senior of the Jindan period listened very carefully, nodded slightly, but didn't say anything.

It is not uncommon for the cultivation realm to kill people and seize treasures and take advantage of people's dangers. The predecessors of the Jindan period expected that this kid must have taken advantage of the danger of others, robbed the pill, and killed the seriously injured Jindan period.

"Uncle Shi, this elixir is so strange, it turns out to be white. It's the first time I've seen it. Guo Yang said in a low voice.

"Yes, I see. The Jindan senior's face was cloudy, and he was forced to be excited, and asked calmly: "How many Peiying Dan did you get?"

"One is a great blessing. For this reason, my subordinates specially consulted a master in the sect who was close to the Zuo Envoy, and his old man told me that this kind of elixir can be met but not sought, and its value is much higher than seven or eight ordinary Peiying Pills. Guo Yang's face was full of admiration, as if he had consulted the Yuan Infant Stage seniors of the Xuanyin Sect.

"Uh...... That's true. Seeing Guo Yang say this, he forcibly suppressed his greed with some surprise, and seemed to be quite jealous of the Zuo envoy.

"Actually, my subordinates were hesitating just now, if that set of array flags can be exchanged for spirit stones, I can consider selling this top-grade Peiying Pill, and then use spirit stones to buy the array flags. Guo Yang said with annoyance.

"You didn't say it earlier!cough!" "Take the Jindan period seniors to easily replace the formation flag for themselves, regretting it, "Virtuous nephew, do you want us to exchange something else?"

Guo Yang shook his head and said, "Forget it." If he let the old man know, I ruined this superb Peiying Pill, I don't know what else I will be scolded for. ”

The senior of the Jindan period scolded in his heart, you kid is such a loser, if I were that old man, I would have torn you into eight pieces and thrown you into the desert to feed the sandworms!

Guo Yang turned around and wanted to leave, and said goodbye: "Uncle Shi, you are busy first, and I will go to other places to have a look." ”

"Senior nephew Guo stays!" Seeing that Guo Yang was about to walk away, the senior of the Jindan period hurriedly said.

"What else does Uncle Shi have to advise?" asked Guo Yang.

The face of the senior in the Jindan period changed, as if there was something difficult to decide, and he gritted his teeth and said, "That's it, I'll exchange other things with you." The quality assurance is no less than that of the Seven Tribulations Array the day after tomorrow. ”

"Oh, what is it?" Guo Yang asked secretly happy.

"Five Elements Detention Spirit Array, have you heard of it?" said the Jindan Stage senior.

"Five Elements Detention Spirit Array, I've heard of it. However, it is said that this formation only exists in the altars of ancient ruins. Guo Yang said, in fact, he has his own set, but now he is temporarily occupied by the shrew of the iron heart.

"The one in the ancient ruins is a dead array, and I'm talking about a living array, a living array that can be used and clothed. The senior of the Jindan period observed the words and saw that Guo Yang was not very enthusiastic about this formation, so he hurriedly said.

"What's the use of this array?" asked Guo Yang.

"There's no way to do it. One of the most important uses is to use the formation to gather nearby spiritual energy and accelerate the cultivation speed. Another usage is to refine the essence of ancient beasts. The senior of the Jindan period said.

When Guo Yang heard that this array could be used to refine the essence of the ancient divine beasts, his heart moved, but he said: "These two wonderful uses are of little use to his subordinates. ”

When the seniors of the Jindan period heard Guo Yang say this, they couldn't help but rub their hands and said, "Actually, the greatest use of this formation lies in its use with other formations. For example, with the "Innate Galaxy Array", you can draw the power of the sun, moon and stars, infuse magic weapons, and refine the best magic weapons to make them have the power of the stars. ”

Guo Yang listened to the Innate Star River Array, which could draw the power of the sun, moon and stars, and his heart was even more moved: "Isn't this a cultivation weapon tailored for me!"

His face was even more worried, and he said: "Uncle Shi, the subordinates of these formations you said sound very powerful, but for me, I really don't know if they are useful." What's more, without the secrets related to the formation, no matter how good the formation is, I can't exert its due power. ”

"In this way, the old man will take the two sets of formations he used and exchange them for your top-grade Peiying Dan. In addition, I will compensate you with a copy of the Ancient Array Relics, how about it?" said the senior of the Jindan period.

"But......" Guo Yang frowned, and stopped talking.

The senior of the Jindan stage gritted his teeth for a while, and said, "Then simply, add another set of defensive array flags similar to the Seven Tribulations Array of the Day After Tomorrow." This array flag is mainly based on the phantom array, supplemented by trapping the enemy, although it lacks the function of the Seven Tribulations, but the power of illusion and trapping is more powerful. ”

"What's the name of this set of array flags?" Guo Yang asked casually, seemingly not caring much.

"Liuding Liujia Formation. The senior of the Jindan period said.

"What's the use of this array?" asked Guo Yang.

"Summoning the Six Ding Divine Fire to burn its three souls, and summoning the Six Divine Thunder to burn its seven spirits. Those trapped in this formation, if they are not born with a strong will, once one of the three souls and seven spirits is dispersed, the divine consciousness will be severely damaged, and at the worst they will dance madly and die. The senior of the Jindan period said proudly.
