In a mysterious unknown space, there is a haze everywhere, filled with the Kuiyin mist emitted by the legendary Kuiyin heavy water. Therefore, the space here is also called Kuiyin Mist.

At the bottom of the Kuiyin mist, there is a vast ocean, which is not an ordinary seawater, but every drop of Kuiyin heavy water weighs thousands of catties.

In the middle of the ocean formed by the heavy water of Kuiyin, there is a huge square surrounded by Kuiyin mist, with a diameter of 10,000 zhang. At the edge of this square, there are five parallel avenues with a diameter of 3,000 zhang, extending outward from five directions, as long as 10,000 zhang. In these five parallel avenues, they are filled with the aura of the five elements of gold, wood, water, fire and earth, while in the central square, the aura of the five elements is mixed.

Therefore, this huge square is also known as the Five Elements Square, and the five parallel avenues that extend out are Jinling Avenue, Muling Avenue, Shuiling Avenue, Huoling Avenue and Tuling Avenue, and the square in the center is called the Central Plaza.

At this time, the Five Elements Avenue was densely packed with people, all of whom came here from the circular spiritual gate at the entrance of the Guò Jiedan Road at various parallel interfaces to participate in the Yudan Road.

People who come to this Five Elements Square from the entrance of the Jiedan Road will be randomly assigned to the Five Elements Avenue of the Five Elements Square. However, Ren Xiaoyao also discovered that people who enter this place through the same entrance will appear in the same avenue.

At this time, in the Golden Spirit Avenue, Ren Xiaoyao restrained his breath, wearing black clothes and black robes, wearing a purple and gold mask, and was strolling around the stalls set up by other monks to see if he could find some treasures.

These foundation building monks from different interfaces will always have some unique treasures that stand out from the crowd. Therefore, most people will not give up this rare opportunity, either set up a stall to buy something, or wander around to see if they can find the treasure they need.

Even, Ren Xiaoyao also found that there were several groups of people who were obviously not on the same interface, but as if they had made an appointment a long time ago, they were communicating with each other secretly, and finally exchanged a storage bag with each other. It seems that this road of knotting Dan once in 60 years has also become an effective channel for the exchange of goods between the major forces at various interfaces.

Seeing this situation, Ren Xiaoyao's mind suddenly became active. Just as people from different interfaces exchange goods through the guò road of knots, the amount of exchange is absolutely amazing. Thinking of this, Ren Xiaoyao's Taobao mind also weakened a lot, and slowly walked around Jinling Avenue, noting the faces of those who exchanged goods between different interfaces.

"Hey, single-attribute materials?" In front of a stall that almost no one cared about, Ren Xiaoyao saw a large number of single-attribute materials, all of which were more than a hundred years old.

"Fellow Daoist, how do you sell this piece of fire attribute fire crystal?" Ren Xiaoyao was just about to go and ask the price, but found that another person preemptively pointed to a brick-sized red ore and asked.

"Don't sell spirit stones, change the pills, five healing pills suitable for my realm are enough. The stall setter said with a somewhat bad face.

Ren Xiaoyao was shocked when he heard this, and he suppressed the urge to buy it and continued to listen. The fire attribute fire crystals on the stall in front of him, if they are placed in the business world, they will be sold for at least 100,000 spirit stones. But the stall holder in front of him only changed ten healing pills, which was really incredible.

"No, it's so expensive, after a while, I entered the road of the Dan, and I couldn't find any single attribute materials. On the contrary, today's healing elixir is priceless. Forget it, I don't want Huoguangjing, farewell. As soon as the other person heard the offer, he was not interested.

"Do you like to buy it or not, if you weren't here, you would have issued a hundred pills, and I wouldn't change them. The stall man snorted and said angrily.

Seeing that a possible business was gone, the stall keeper sighed softly. Seeing this, Ren Xiaoyao swept this person slightly, and then he knew that although this person was in the late stage of foundation building, he was seriously injured. If nothing else, the probability that this person can get out of the road of Yudan alive is very low.

"Fellow Daoist, if I use this elixir to exchange these single-attribute refining materials with you, how are you going to exchange them?" Ren Xiaoyao handed the stall holder a low-grade Yuan Ling Pill and asked.

Hearing that someone was willing to exchange the pill for his own materials, the stall setter's face was overjoyed, and then when he looked at the pill in Ren Xiaoyao's hand, his face showed ecstasy. But soon, this person suppressed his ecstasy again, pondered for a while, and said in a semi-negotiable tone: "If my single-attribute materials are taken outside, they can be sold for at least one million lower grade spirit stones." But now in this place, the materials are not valuable, so I will exchange you for fifty, oh no, only thirty of these pills will do.

"One price, twenty pieces, if you don't change it, I'll leave immediately. Ren Xiaoyao said in a flat tone.

Although the price of this stall is extremely low, it is slightly higher than the previous price. Ren Xiaoyao is not related to the person in front of him, so naturally he will not let him take advantage. On the contrary, this person is now in urgent need of healing pills, and Ren Xiaoyao can still take advantage of it.

"That's it, if there is no healing pill, with my current state, I'm afraid I won't be able to live this path of knotting, so let's change it. The stall man sighed, received a roll of single-attribute materials on the stall, and handed it to Ren Xiaoyao in an empty storage bag.

Ren Xiaoyao took the storage bag, and also filled the empty storage bag with twenty lower-grade Yuan Ling Pills, and handed them to the stall holder.

"I still have a lot of single-attribute materials here, do you want to?" Just as Ren Xiaoyao was about to leave, the stall setter suddenly and mysteriously transmitted a message to Ren Xiaoyao.

"How do you change it?" Ren Xiaoyao stopped his steps, turned his head, and asked in the same voice.

"The same is the same for the healing elixir, but the quality must be at least high-grade, if there can be a semi-superb or even the best healing elixir, I can change it for more single-attribute materials for you. The stall holder seemed to see that Ren Xiaoyao was more concerned about single-attribute materials, and flicked one hand to his waist, then handed Ren Xiaoyao another empty storage bag, and lowered his voice and said: "This is a two-thousand-year-old fire attribute fire crystal, and I still have a large number of single-attribute materials here, ranging from one thousand to five thousand years." ”

"I'm going to look at the goods first, if your goods satisfy me, the elixir I gave you will definitely have no problem treating your injuries. Ren Xiaoyao said quietly.

"You know I'm hurt?"

The stall setter suddenly looked alert, but then sighed again and said calmly: "Okay, although I try my best to cover it up, it is not surprising that someone found out that I was injured in the Crouching Tiger, Hidden Dragon in the road to the end of the Dan. These materials were originally intended to be used for trading with other interfaces, but the other party didn't come at all, and we encountered other strong enemies, and I was the only one left in the entire alliance, and I was seriously injured. Now I don't even know if I'll make it back alive, so why should I keep these materials?"

After the stall keeper finished speaking, he took out another storage bag from his arms and handed it to Ren Xiaoyao, but this person's divine thoughts were still left in the storage bag, and he could urge the storage bag to fly back or detonate the storage bag at any time.

Ren Xiaoyao took the storage bag and checked the inside of the storage bag without disturbing the other party's thoughts.

After a dozen breaths, Ren Xiaoyao showed a hint of shock on his face and took his divine thoughts back from the storage bag. Then, Ren Xiaoyao also took out an empty storage bag, separated ten pills from the storage bag, and handed them to the stall holder.

"There are ten pills here, more than enough to treat your injuries. ”

Hearing that there were only ten pills, the stall setter looked dissatisfied, but he still took Ren Xiaoyao's storage bag, and his mind reached into the storage bag. Immediately, the stall setter looked excited, and even trembled a little because of the excitement.

"It's!"

The pill that Ren Xiaoyao gave him was ten top-grade Yuan Spirit Pills, which were suitable for his current injury. Even, after completing taking these pills, maybe his cultivation could be further improved.

Although from the outside world, the value of the pill given by Ren Xiaoyao is far less than the value of the materials in the stall person's storage bag, but the stall holder is still afraid that Ren Xiaoyao will regret it, so he immediately broke the divine thought on the storage bag in Ren Xiaoyao's hand, and at the same time took Ren Xiaoyao's storage bag into his arms.

Seeing this, Ren Xiaoyao was overjoyed, and also broke off the divine thoughts he left on the storage bag in the hands of the stall keeper, and after arching his hand slightly to the stall keeper, he turned around and left.

The value of Ren Yao's ten top-grade Yuan Spirit Pills, if they are converted into lower-grade spirit stones, will not exceed 500,000 lower-grade spirit stones. However, the single-attribute materials in the stall holders' storage bags are worth at least 50 million or more lower grade spirit stones. Therefore, Ren Xiaoyao is actually a little afraid that this stall maker will regret it.

"Look, there's a fight over there!"

I don't know who shouted, causing a commotion in the crowd.

Not far away, the sound of weapons intersecting was endless, and dozens of figures mingled in the air, and beside them, hundreds of foundation building monks watched from afar.

In this Five Elements Square, foundation-building monks like this who fight for various reasons happen all the time.

Seeing that someone was fighting in front of him, Ren Xiaoyao slowly turned around and walked towards the other side of the seemingly calm place.

It's not that you're afraid of things, but it's better to have more than less.

According to the information collected by Ren Xiaoyao about the path of Yudan, after the foundation building monks of each interface entered this Five Elements Square, they had a three-hour rest. Three hours later, the road to Yudan officially began.

In these three hours, Ren Xiaoyao wanted to visit these five elements space more, and took this opportunity to collect more information on other interfaces, and also find more treasures for himself.

Three hours is not enough to even finish walking around this Golden Spirit Avenue, how can Ren Xiaoyao have time to grudge and fight with others. However, if someone doesn't look for trouble with Ren Xiaoyao, Ren Xiaoyao will definitely not be polite.

At the edge of Jinling Avenue, there was a thin layer of transparent mucous membrane standing up to the sky, isolating the Five Elements Avenue, and the gray and hazy Kuiyin mist at the other end of the mucosa could be vaguely seen. Each foundation building monk tried to avoid the edge of the Five Elements Avenue and try to stay away from the transparent mucous membrane.

This mucous membrane looks thin and can be broken by blowing, but the Kuiyin mist at the other end is something that no foundation building monk dares to provoke. Moreover, this mucous membrane has a characteristic that it can easily enter the Kuiyin mist from the Five Elements Avenue, but once it enters the Kuiyin mist, even if it is not crushed by the Kuiyin mist, it will never return to the Five Elements Avenue because of the obstruction of this mucous membrane.

It is precisely because of this layer of mucous membrane that all the foundation building monks who participated in the path of Yudan tried their best to move closer to the middle of the Five Elements Avenue. Even if there is a fight between monks, try to stay away from the edge of the Five Elements Dao.

As soon as he thought of the magic of this road to the knot, Ren Xiaoyao couldn't help but come to the edge of this Golden Spirit Avenue and carefully looked at the transparent mucous membrane at the edge.

But at this moment, Ren Xiaoyao's face suddenly froze, his body shook, and he moved three feet to the left out of thin air.

Where Ren Xiaoyao was originally standing, a sword mark that was a zhang long appeared on the ground. Not far behind Ren Xiaoyao, more than a dozen uniformly dressed monks were holding swords in their hands and looking at Ren Xiaoyao with malicious intent.

Looking at his clothes, he turned out to be a person from the Medicine God Sect.

"Ren Xiaoyao, you traitor, where do I see you fleeing today?" said one of them with a sneer.

Seeing this, Ren Xiaoyao was curious, and the killing machine was even stronger. Ren Xiaoyao was now wearing a black robe that could isolate divine thoughts, and he was wearing a purple gold mask that even the Dan monks couldn't see, but even under this disguise, he was still discovered by the people of the Medicine God Sect.

This only shows one situation, the people of the Medicine God Sect have another way to find Ren Xiaoyao.

At this time, Ren Xiaoyao thought of the Blood Soul Lamp of the Medicine God Sect, and the trace of good feelings for the Medicine God Sect in his heart was completely gone, only the chill remained.
