The underground exchange is just a name between monks, the founder of this underground exchange is a well-known chamber of commerce on the mainland, the Wanmeng Chamber of Commerce, the underground exchange is one of the industries of the Wanmeng Chamber of Commerce, the Wanmeng Chamber of Commerce was established for a long time, only do business, never participate in the struggle, but the strength of this chamber of commerce is no one questioned, it is said that the number of monks in the chamber of commerce is comparable to the five holy sects.

There was a small remote courtyard in the south of the Fire Spirit Holy City, and the courtyard was very quiet, only a few foundation building monks were talking to each other inside. At this moment, a black-robed guy walked into this small courtyard, and several monks in the courtyard suddenly became alert, looking at the monk in front of him, the black-robed man in front of him gave people a sense of danger everywhere, and this person's cultivation had reached the realm of the late stage of the Yudan.

"Who are you, what are you doing in my small courtyard?" among the several monks, a middle-aged monk stepped forward and asked Zhou Changqing.

"You don't care who I am, I'm going to post a transaction and record it for me!" a slightly domineering voice came from the black robe.

"Senior, do you have a letter of introduction from my Wanmeng Chamber of Commerce?" Several monks glanced at each other, and it was still the middle-aged monk who asked Zhou Changqing.

"Whoosh!"

A blue card flew into the middle-aged monk's hand.

"Senior, please come with me!" The middle-aged monk looked at the card in his hand and stretched out his hand to make a gesture of please.

This black-robed man was naturally Zhou Changqing, and Zhou Changqing followed the middle-aged monk all the way to the deepest part of the small courtyard.

There is a rockery in the deepest part of the courtyard, the rockery has different shapes, which makes people look quite weird, and the two came to a rockery that looks like a giant turtle. The middle-aged monk stopped his steps, the light flowed between his hands, and one after another magic seals were punched out, and the giant tortoise in front of him was actually split in two from the middle, and a wide underground staircase was revealed, and there was no end in sight.

"Senior, please go in! When you get inside, someone will come to pick you up!"

Zhou Changqing walked down the stairs, the hole above his head suddenly closed, Zhou Changqing fell into a darkness, only a glimmer of light could be faintly seen in the distant underground, Zhou Changqing stepped down the steps step by step, and the light in the distance became brighter and brighter, until Zhou Changqing walked into an underground square, and a Qi Cultivation Realm monk was waiting on the edge of the square.

The underground square is not lively at this time, there are not many people in the square, only a few dozens, and there are only five or six people who set up stalls, all of whom are guys in black robes, and they use hidden secret methods, so that people can't see the original appearance and breath clearly.

Zhou Changqing's arrival also attracted the attention of some people, but he only glanced at him twice and stopped paying attention. Zhou Changqing didn't plan to visit those stalls, most of the things sold here were things that didn't open the right way, and most of the things that could make Zhou Changqing look good would not be available here.

Zhou Changqing followed the Qi cultivator who led the way all the way to a place called the Barter House, and Zhou Changqing stepped into this small palace in one step.

Zhou Changqing looked around and found that there was only one old man lying on the recliner behind the table, this old man's cultivation Zhou Changqing couldn't see through it, Zhou Changqing couldn't help but squint his eyes, and walked towards this old man.

The old man seemed to sense someone approaching, and turned his head to look at Zhou Changqing.

"Barter, barter, what does this fellow Taoist want?" the old man's mouth obviously didn't move, and a slightly low voice came out of his body.

"Ten Thousand Years Shaping Flower!" Zhou Changqing still had that domineering tone.

"Ten Thousand Years Shaping Flower!" the old man muttered.

"This kind of elixir is rare! It is a relatively rare seven-grade elixir! I remember that a long time ago, there was a monk who wanted to exchange for a sixth-grade barrier-breaking pill, but I don't know if it was exchanged, let me take a look!" the old man frowned and thought carefully.

Zhou Changqing couldn't help but be overjoyed when he heard this, he didn't expect that he had just arrived at this so-called underground exchange and had the news of the Ten Thousand Year Shaping Flower.

The old man got up from the chaise longue and walked to the sea file behind him to look it up.

"Oh! here, it hasn't been exchanged yet, it's really good luck for Daoyou!" After a while, the old man took out a copy of the pile of files, opened it and looked at it, and threw it into Zhou Changqing's hand.

Zhou Changqing took it and took a look, and there was indeed a strange flower with an ever-changing shape on the file, which was undoubtedly the 10,000-year-old shaping flower.

The barrier breaking pill's Danfang Zhou Changqing had already been exchanged, and he was about to start refining, but he didn't expect that this time he would be able to exchange it for another 10,000-year-old shaping flower by the way.

"I can bring this barrier-breaking pill in a few days, I don't know where this 10,000-year-old shaping flower is?" Zhou Changqing asked lightly.

"Naturally, it is at the headquarters of my Wanmeng Chamber of Commerce, but Daoist friends can rest assured, after a few days of hard work, the 10,000-year-old shaping flower will definitely be sent to my Fire Spirit Holy City Branch. The old man said with a smile.

Zhou Changqing didn't speak again, turned around and left here.

The news that the young man of the Liu family was going to marry Shen Ruoxue of the Shen family had spread throughout the Fire Spirit Holy City in the past two days, and the number of guests coming and going between the Liu family and the Shen family had also increased day by day in the past few days. Zhou Changqing was not in a hurry to go to Liu's house, there were still two days before the happy day of the Liu family, Zhou Changqing felt that the matter of the Ten Thousand Years Shaping Flower could not be delayed, so he went to several elixir shops to buy dozens of medicinal materials for the six-grade barrier-breaking pill and dozens of medicinal materials for the third-grade to five-grade barrier-breaking pills, which cost him nearly a thousand Qingling beads, making his heart drip blood, he really wanted to take the identity token of the earth dog again.

There was not much time, Zhou Changqing didn't start refining from the three-grade barrier-breaking pill, he directly began to refine the six-grade barrier-breaking pill, the result can be imagined, with the assistance of ten thousand yuan to one furnace, he also wasted nearly eight medicinal materials to refine the first furnace, Cheng Dan is only three, eight medicinal materials are nearly two hundred cyan spirit beads! The price of these three barrier-breaking pills is a bit big.

But after Zhou Changqing's refining was on the right track, and he refined three furnaces one after another, a total of 17 pills, Zhou Changqing put away the pill, came to the underground exchange again, and changed the 10,000-year-old shaping flower to his hand, and took out three more pressed on the underground exchange to exchange for three 10,000-year-old shaping flowers again.

Zhou Changqing took a messenger and recorded the underground exchange, Zhou Changqing only then knew how the underground exchange was profitable, the monk pressed the things in the underground exchange, he would get a messenger, if the deadline expired and there was no trading result, the exchange would return the item, if the monk had died, the messenger would lose its effect, and the things pressed in the underground place would naturally belong to the underground place. This is really a business without capital!" Zhou Changqing couldn't help but sigh.
