"Rare metals, bought, are there any other good things?" asked Chen Feng.

"Of course there are some, boy, it seems that you don't have to go anywhere else, you can break through the Golden Cave when you go back this time, guess what I saw?" Ta said with a smile.

"Superb metal ore or metal demon core?" Chen Feng said, his gaze began to sweep, and he quickly fixed his gaze on a stone box, because Chen Feng felt the faint power of rich gold from it.

"Yes, this stone box is a metallic demon core, and it is also a demon core that has survived two thunderstorms, this demon core alone is enough for you to open up the Golden Cave, but I'm not talking about this, but other things, the usefulness of this thing is more precious than this demon core. Ta said with a smile.

"What the hell is it?" Chen Feng's appetite was mobilized.

"It's a piece of cold iron crystal, tsk, boy, if you don't need it, I'd want to devour it. Ta said with a smile.

"Cold Iron Crystal, you're talking about this piece. Chen Feng said and picked up the black metal ore, which looked like an iron lump at first glance, but it sank suddenly in his hand.

"It's so heavy, this piece is not as big as a fist, and there are thousands of catties, which is too exaggerated. Chen Feng said in surprise.

"This is the essence of the cold iron condensed, naturally it can't be the same weight as ordinary cold iron, just this piece of essence, it is enough to compare to a demon core that has survived five thunder tribulations, boy, buy it quickly." Ta said with a smile.

"How do you sell this?" Chen Feng asked with a smile while holding the Cold Iron Crystal in his hand.

"Inner disciple?" The stall owner was a middle-aged monk, a cultivator of the eighth layer of the secret realm, but Chen Feng had already felt a faint aura of twilight from this person, and he knew that this person's lifespan was coming to an end, if he couldn't break through again to increase his longevity in a short period of time, then the result would be a slow death.

"True Disciple. Chen Feng smiled, seeing that the other party didn't believe it, he had to take out a token symbolizing the true disciple, but at the same time, he also felt a little emotion in his heart, this person couldn't even see his own soul fire, and he was also a monk who condensed Zhou Tian's power.

Seeing the token in Chen Feng's hand, a look of surprise flashed in the eyes of the middle-aged monk, but it quickly disappeared.

"You want this piece of iron essence?" said the middle-aged monk lightly.

"Not bad, what price?" said Chen Feng with a smile.

"For the sake of seeing that you are a true disciple, I will give you a preferential price, 10,000 magic crystals. The middle-aged monk's tone was still flat, but the expression on his face showed that he didn't believe that Chen Feng would buy it.

"No problem, deal, and I want all these metal ores. Chen Feng said with a smile.

Hearing Chen Feng say that he wanted it all, the middle-aged monk was even more surprised, he did have some precious metal ores on his stall, and he was reluctant to take them out, some of which he originally kept to create a magic weapon, but as time went by, his cultivation has not been able to break through, and seeing that Shouyuan was about to end, he had no choice but to take out the precious ore on his body and exchange it for some magic crystals for his own cultivation.

But I didn't expect that I hadn't sold much in a few days, and the magic crystals I got were not enough for my own cultivation, and what I didn't expect was that I actually met a big customer today, and this big customer was still a small true disciple.

"What, are you afraid that I don't have a spirit stone?" Chen Feng said with a smile.

"Hehe, it's not, if you want to buy metal ore, I still have some on me, but I don't know if you can eat it, little brother?" said the middle-aged monk after thinking for a while.

"No matter how many rare ores you have, I can eat them. Chen Feng smiled and waved his hand, and 10,000 magic crystals were placed in front of the middle-aged monk.

"This is the price of this piece of iron. Chen Feng smiled and put away this piece of cold iron crystal essence as soon as he changed his hand, and with this piece of cold iron crystal essence, Chen Feng's golden acupoint could be opened up.

"Okay, since the little brother is refreshing, then I am also refreshing, and I do need a large number of spirit stones. The middle-aged monk said as he took out some metal ore from the space bag.

Sure enough, the quality of these newly taken out metal ores was indeed much better than the quality on the stall, and several of them could be compared to the cold iron crystal.

"Da Luo Jin Jing, Iron Phantom Sand, Five Elements Essence Gold, good things and good things, haha, this piece of Five Elements Essence is more suitable for you than the Cold Iron Crystal Essence just now. Ta laughed in the Tower of Immortality.

"There are also 10,000-year-old iron essences and Lei Zesha, boy, hurry up and buy all these things, you don't need so much, I will devour all the rest." Ta continued.

"This senior brother, in addition to metallic ores, I also need good things with other attributes. Chen Feng said with a smile, seeing so many good things, Chen Feng secretly thought in his heart that there should be other good things on this person.

"Oh, it's funny, the most precious thing on my body is these ores, hey! If I hadn't suddenly become obsessed with mining, I wouldn't have spent so much time that I couldn't go any further. The middle-aged man's face was a little gloomy as he spoke.

"Please ask Senior Brother to set a price. Chen Feng also saw that the middle-aged man in front of him was not in a very good mood.

"Give a total of 100,000, 100,000 magic crystals will do. The middle-aged man took a long breath and said in a deep voice, looking at the ore in front of him with some reluctance.

"This is 200,000 magic crystals. Chen Feng directly doubled it.

"How can this be. The middle-aged monk refused.

"I know the price of these ores, if you say 100,000, Senior Brother is really at a loss, and besides, I don't have any bad magic crystals on me, and I also have a request. Chen Feng said with a smile.

"Speak. The middle-aged monk's expression was a little solemn.

"I hope that Senior Brother will have precious metal ores to keep for me in the future. Chen Feng said.

"There's no problem with this, but it's a pity that if I don't break through my cultivation, I'm afraid I won't have time to mine ore. The middle-aged man nodded and said.

"You kid is treacherous, these ores can't be bought even by a million magic crystals, and you still have the expression of a good person. Ta said with some disdain.

"Hey, what you're talking about, isn't it like no one buys it. Chen Feng retorted.

After saying goodbye to this middle-aged man, Chen Feng went to some other stalls and bought all the things that could be seen, and when Chen Feng walked in front of the demon core of the metallic demon beast, Chen Feng had already spent two million magic crystals.

"Senior brother, what is the price of the demon core in your box?" Chen Feng asked with a smile.

If Chen Feng had come to this stall to inquire at the beginning, it was estimated that the other party would not have bothered to take care of Chen Feng at all, but now it is different, Chen Feng has bought all kinds of ores in this exchange place and spent a lot of magic crystals, and this situation has been seen by many people.

Now most people regard Chen Feng as a fat sheep with a background background.

"Are you sure you want this demon core, this is a metallic demon core that has survived two thunder tribulations, as for the value, you should also know, besides, you don't seem to need it, right?" The stall owner is a young man who looks a little sloppy, with the cultivation of the ninth layer of the secret realm, in Chen Feng's feeling, this person is not far from the realm of heaven and man, at least Chen Feng's feeling is much more powerful than Sun Xuan's.

"Yes, I bought it naturally useful, senior brother make a price. Chen Feng said with a smile, although the things on Chen Feng's body were enough to open up the golden hole, Chen Feng was still unwilling to let go of such a good thing as the demon core, and the metallic level demon core was not common.

"A million magic crystals, no counteroffer. The breathless young monk held out a finger and said with a smile.

"No problem, deal, I want this demon core. Chen Feng said and directly handed the other party a space bag, which contained a million magic crystals.

The young monk took it and looked at it, then grabbed the stone box and stuffed it directly into Chen Feng's hand.

"I said Luo Bo, there are a lot of spirit stones on this kid you brought, but why does he buy metal ores so hard?" someone asked Luo Bo strangely.

"Maybe it's to build weapons. Luo Bo replied casually.

"Cut, what about the liar, there are so many magic crystals, what quality magic weapons can't be bought. ”

"But I can't figure out what this kid is doing when he buys that demon core, this kind of thing is just an ornament when he buys it back, and our monks can't refine and absorb it, and I don't think this kid named Chen Feng looks like he can do alchemy. ”

"Wait, I'm going to have this demon core. At this time, a voice suddenly sounded, and the tone was very flamboyant, which immediately alarmed the surrounding monks.

"Hey, Robo, you're in trouble little brother. "Someone else stabbed Robo.

Chen Feng had just opened the stone box and had not yet put it away when he heard this provocative voice, and as soon as he turned his head, he saw Zhao Quan leading a group of ** steps over.

Speaking of which, Chen Feng didn't put Zhao Quan in his eyes at all, just a gentleman who only knew how to eat, drink, and have fun and was domineering, but what surprised Chen Feng was that the last time he saw Zhao Quan, the other party was only at the fourth layer of the secret realm, and now he has reached the sixth layer of the secret realm, and he has also condensed the soul fire.

"Could it be that this kid has eaten an anti-heaven elixir, but I'm afraid that the soul fire thing can't rely on the elixir alone, and it still needs a strong will. Chen Feng said secretly in his heart.

"I want this demon core, let's make a price. Zhao Quan had already come to Chen Feng at this time, and directly reached out to grab the stone box in Chen Feng's hand.

Chen Feng's palm shook, and Zhao Quan grabbed the air, so Zhao Quan continued to shoot, and the shadow of the claws in the sky shrouded the stone box in Chen Feng's hand.

In the face of this kind of attack, Chen Feng's palms kept shaking, but the expression on his face was very casual, and the corners of his mouth showed a hint of sarcastic smile, which did not put Zhao Quan in his eyes at all.

Zhao Quan hit out hundreds of claw shadows in a row, all of them failed, Zhao Quan's face was difficult to see, originally Zhao Quan wanted to find a place to show off his might after his cultivation skyrocketed, and he happened to meet Chen Feng, a guy who had a holiday, and Chen Feng was only in the realm of the fourth layer of the secret realm, so Zhao Quan was excited to come over and teach Chen Feng a lesson.

Unexpectedly, the result was like this, looking at the sarcastic smile on Chen Feng's face, Zhao Quan wanted to roar loudly in anger.
