Heaven-defying Upgrade System

2"Oh, so you're out of town, so it's normal you don't know. This Black Bull's name is not small. He has some connections when he finds things. It's said that many of them are relatively precious, but they are all black goods. Although the price is relatively low, not many people dare to buy them. " The man said.    

    

Liu Fei and the others nodded. There were many such people. They were the ones who earned money from the dead, the things that came out from the bodies of the dead cultivators. Or perhaps there was a war going on there. They would all go there to clean up the battlefield. However, the biggest source was none other than the thieves who stole people's things. They would sell their goods to the black market buyers, such as the black yak. These people were all people with backgrounds in the black market. Some could even be said to be core members of the black market.    

    

Thus, even if those who were stolen knew that their goods had already fallen into the hands of the black yak. If they didn't have a strong background, they would only be able to eat without saying anything. Many people liked people like the black yak more than others. They could buy things they couldn't afford from the black yak at a low price. However, it wasn't entirely beneficial. As the saying went, No business but no evil. This black bull was also very astute. He knew that many people were greedy, so he would deliberately sell some of the things that he originally sold at a very low price. He would increase the price so that the things he bought would be good and bad at times. It would depend on their luck or judgment.    

    

If they bought it at a loss, there would be no place to reason with them.    

    

If they bought it, they would earn it, but they wouldn't forget to give the black yak a good review. This way, his business would definitely not suffer any losses. Moreover, this thing is competing in reputation and strength. You are strong enough. Naturally, there would be people going there to buy it. At that time, there would be more and more people. There are also many sellers like the black yak in this black market, but their reputation is not as good as his. Therefore, when the black yak ate meat, they would also get a share of the soup.    

    

Liu Fei sat there and thought to himself. The auction would start soon anyway. He could go and take a look since he still had a lot of money in his pocket. If he ran into anything good, he could buy some for his brothers. Thinking of this, they threw a wreath here. Even if there were already people here, they would go straight to the black yak.    

    

The yak's name was just like a human's. He was black and muscular, and he wore a big grey robe. His stall was also long enough for him to sit there and sell the things in his stall. From one end to the other, it was at least ten meters away. There were all kinds of things on it. There were all kinds of strange things.    

    

Customers who came to buy here could observe it at will. There were also clear prices on it. For example, there were a few Green Source Crystal Stones, green energy crystal stones, or points written on it. However, he could bargain here. Of course, what was more interesting was that... The seller could even bid higher.    

    

So, if you don't know what's good for you, it's best not to say it out loud. Otherwise, if others start to talk sense into you, you'll have to spend more money to buy it. At that time, not only will you lose face, but you'll also lose face.    

    

"Black yak, how much do you sell this short sword for?" A cultivator picked up a short sword from his stall and looked at it for a moment.    

    

"Four green crystals, or four hundred thousand points." The black yak glanced at it and pointed.    

    

"Hehe, do you really think I've never seen a magic weapon before? How dare you ask for 400,000 points for such a broken item? It's only a low-grade magical artifact! " The cultivator said aggressively. It seemed like he wanted to challenge the black yak.    

    

Liu Fei's eyes moved again and looked at the short sword in the cultivator's hand. It seemed to be made out of pure materials and was made of Heavenly Gold Sand and a small amount of cold iron. It was indeed a good thing. Although it cost 400,000 points, it looked like it was asking for a sky-high price. However, this price was quite generous for such a magic weapon.    

    

Liu Fei nodded his head, agreeing with the black yak's honest attitude.    

    

"Hehe, although this thing isn't a particularly good magic weapon, it's not bad either. If you really want to fight with it, you can use it to ensure its effectiveness. As the saying goes, every inch is short, and every inch is close to danger. Moreover, it is an artifact forged from Heavenly Gold Sand and Cold Iron. The material is quite hard. I guarantee that you will not be able to break it, and it will be difficult for others to defend against it! " The black yak sneered.    

    

Liu Fei could hear what the black yak said. He seemed like a person who was good at studying martial arts. Judging from his cultivation base, he should be about to break through to the Earth Core Stage.    

    

Although Spiritual Core Stage was a bit weak for Liu Fei, for ordinary people, Spiritual Core Stage was still considered a very powerful existence.    

    

"Yo, black yak, you have been selling things for a long time. Who doesn't know the rules of this place? Will you suffer a loss? You said this thing was worth a lot of money today. Is it worth a lot? You better prove it to me!" The cultivator said without any restraint.    

    

The atmosphere instantly turned cold. Ordinary people wouldn't dare to talk to the black yak like this. However, the yak was a very experienced and calm person. He didn't have much to say to this hot-tempered young man. He stood up slightly. He slowly walked in front of the cultivator. Then he said to the cultivator: "Since you like this short sword, you must be an expert in practicing short swords. Take out your weapon and compare it with the short sword in my hand. What do you think? ? "    

    

The cultivator's eyes moved and he said, "Alright, I was waiting for you to say that. Come on!"    

    

After saying that, he took out a short sword from his pocket and flicked it lightly. Immediately, a clear and melodious sound was heard. Hearing this sound, the surrounding people could not help but discuss it.    

    

"This short sword's quality is not bad!"    

    

"It doesn't look like a weapon forged by an ordinary blacksmith."    

    

The people around looked at the short sword curiously, but those people were the same as Liu Fei. They weren't interested in the short sword, they were just watching the show. And even more people who came to watch the show were just there to watch the show. More and more people came to watch the show.    

    

"It should be a weapon forged by a famous refiner. There is a bit of fire jade in this short sword. There is also a portion of spirit wood, and the remaining portion is red copper. There is a small formation inside. The forging time should be endless. For cultivators, this is indeed a very good weapon. It's much better than the short sword just now. " Huo Feng said in a deep voice. He had seen a lot of things.    

    

Since Huo Feng said so, there was no need to watch the competition anymore. The black yak would definitely lose.    

    

The others nodded in agreement. Xiao Ruyu and Lu Shuang could not see anything. They just scratched their heads curiously and looked at each other. Liu Fei looked at the dagger of the black yak. If it was just the level of forging Liu Fei saw just now, then... The black yak shouldn't be emitting such a biting cold aura in its hand right now, which made Liu Fei feel strange. It might be a rare treasure, and its price would definitely be more than four pieces of green energy crystal. It might even be higher.    

    

However, the origin of this thing was unknown, so the price should be like this.
