Yi Feng could be said to know nothing about Black Abyss City, but the Xue Yue beside him was quite familiar with this place. Thus, the two of them strolled around Black Abyss City.
Hei Yuan City was much larger than Yuan Tan City and was divided into internal and external cities. The outer city was where the martial artists gathered, and it was mainly used to protect them from the danger. The inner city was a place where hundreds of people lived. Its prosperity was even greater than the Lin Xuan City where the Yi Family resided.
Yi Feng and Wang Lin were currently wandering around in the inner city. Perhaps it was because they had been cultivating for a long time and it was rare for them to have such a relaxed time. The two of them had a tacit understanding of each other and felt this rare moment was ordinary.
In the bustling street, all sorts of shouts, laughter, and quarrels were mixed together. However, the noise in their hearts was full of flavor.
Yi Feng did not dare to have any other thoughts towards this beauty beside him. Right now, he only had one mission, and that was to become stronger.
"There's a trading ground in Black Abyss City. The people from the outer city occasionally trade the items they get at the outskirts of Netherworld Valley. Although their value isn't very high, it's still worth taking a look." Xue Yue who was walking suddenly whispered to Yi Feng.
"Oh? "What's usually traded there?" Yi Feng, on the other hand, was quite interested in the trade center. He had never participated in such transactions before.
The Nether Tomb was not like the other empires inside. It had its own Weapon Guild and Pills Hall. This place focused on trading goods with others. In a very small number of auction places, the items inside were extremely expensive. They weren't something that a low level martial artist could participate in.
"There's everything, but most of them are low-priced cultivation techniques or weapons. There are even some strange monsters." Xue Yue explained.
"Then let's go for a stroll. There's nothing else to do anyway." Yi Feng said with a smile, following Xue Yue.
The two of them were not in a hurry and their speed was slow. An hour later, the two of them appeared in a rather remote alleyway. They then turned a corner and entered a courtyard.
This courtyard was rather large, and was able to accommodate a hundred people at the same time. Currently, there were already quite a few people in the courtyard. There were many stalls on the ground and many items on top of them.
There were quite a few people looking at the stalls, apparently looking for what they needed, but most of them shook their heads and headed for the next one.
Many vendors were chatting with each other. It seemed that not many people came to exchange goods.
When Yi Feng and Xue Yue appeared in the courtyard, almost everyone stopped what they were doing and looked at them. Most accurately, they were looking at Xue Yue.
Xue Yue was indeed beautiful, even Yi Feng couldn't help but stare at her. However, these people's performances were a bit too exaggerated. Some of their faces even turned red.
Xue Yue didn't seem to notice the gazes of the crowd as she started to look through the items one by one.
Generally, the stalls held the leather armors of low level beasts and other low level items. It was basically useless to the two of them. Moreover, Yi Feng's wealth could be described as terrifying.
After inspecting several stalls, the two of them did not find anything of value. However, the two did not have much hope for this place and only had the time to take a stroll around.
A middle-aged man walked towards the two as he looked at the items in front of a stall. He looked extremely wretched, making it difficult for him to give a good impression of him.
"You two, the things here shouldn't enter your eyes. If you go to my stall and take a look, I have something that you two might be interested in." The middle-aged man said with a wretched smile. His eyes never left Xue Yue for a moment.
"Hmph." Xue Yue snorted lightly as an intense aura burst forth from her body.
This was an aura that only a Superior Grade Martial Master could emit. The strongest cultivator present was only a Primary Martial Master, so how could they stop Xue Yue's aura? The martial artists who were closer to Yi Feng and Xiao Feng immediately took a few steps back.
Only then did the middle-aged man know that this extremely beautiful woman wasn't just a flower vase. Her cultivation was high, and she wasn't someone he could mess with.
The middle-aged man put away the wretched look on his face, and his expression immediately became righteous. He said respectfully to the two men, "I was presumptuous just now. Please do not blame me."
Only the strong could be respected.
"Take us to see something." Yi Feng said lightly.
The middle-aged man nodded and brought the two to his booth. The middle-aged man only had one item on his stall, and it was a blue stone about the size of his palm.
This blue stone did not look like it had any special features. There were even more gorgeous stones than this one, and their color alone could not prove its value.
I found this blue stone on Black Wind Mountain by accident. To be honest, I don't know what it can be used for." However, his tone was a bit embarrassed. This blue stone had been sold for a long time, but it hadn't sold out. Who would believe that a stone that even he didn't know its use was a treasure?
Xue Yue picked up the blue stone and examined it for a while before handing it to Yi Feng. She shook her head and whispered, "I can't see what use this stone has, but its hardness is quite good."
Yi Feng took the rock and looked at it for a while, but still couldn't find anything. However, since Xue Yue said that its hardness was good, he might as well inject his zhen qi to try it.
With the experience of opening the Purple Cloud Boots, Yi Feng did not choose to use a strand of true energy. Instead, he poured his Five Elements true energy directly into it to see if it could absorb a certain strand of true energy.
As soon as he injected the zhen qi, Yi Feng was startled. The blue stone was really absorbing his zhen qi. After a while, Yi Feng stopped pouring his zhen qi. His heart was full of shock.
While he was shocked, Yi Feng's face remained calm. He raised his head and said to the middle-aged man in a low voice, "Other than the fact that this thing is very hard, it has no other use."
"Sigh, I've always thought that it was a treasure. However, up until now, no one has been able to recognize it. Perhaps it really is only an ordinary decorative stone." The middle-aged man's expression was decadent. Even a Martial Grand Master said that this item had no value. It seemed that it was truly a rock.
"Sell it to me at a low price. Go home and use it as an ornament." Yi Feng said with a regretful expression.
"Since it is an ordinary stone, I shall give it to you as an apology for your rudeness just now." The middle-aged man shook his head and smiled bitterly. A normal stone was worth a few coins, he might as well buy two people.
"I don't like to owe favors. This is a bottle of Fasting Pill. Although it's not a high-level medicinal pill, it's still practical. How about I use it in exchange for this stone?" A small porcelain bottle appeared in his hand. Although he had yet to figure out the uses of the blue stone, Yi Feng knew that it was not a simple item when he injected his zhen qi into it. Since he had taken someone else's item, Yi Feng would use the Fasting Pill to compensate.
Hearing this, the middle-aged man was overjoyed. He was only a beginner warrior, and he himself did not want to buy this pill. To be able to trade a piece of rock for a bottle of Fasting Pill, it was definitely worth it.
Casually storing the blue stone into their storage ring, the two of them continued to stroll around the other booths until they couldn't find anything of value. Only then did they leave.
However, Yi Feng was ecstatic inside.
