"Hahahaha, the black dragon stone of shit, this kid is just fooling, this is simply a piece of 10,000-year-old iron essence, but one thing this guy is right, that is, this iron essence can indeed make a treasure. Tadaxiao said.

"Does it work for you?" Chen Feng asked.

"Of course it works. ”

"That's good. Chen Feng nodded, and then asked, "How can this black dragon stone be sold?"

"Hahahaha, I really met a big boss today, I didn't expect this silly boy to be so stupid, but it's also stupid and cute, hahaha. The middle-aged monk's heart was filled with joy.

"This black dragon stone is worth ten thousand, no, no, no, no, one thousand, no, no, no, one hundred magic crystals. The middle-aged monk said as he looked at Chen Feng's face.

"It's still ten magic crystals, I said this uncle, you have to be honest in business, why are you asking for a price indiscriminately, forget it, I'll go to other places to see." Chen Feng shook his head and said.

"Slow down, don't go, don't go, ten dollars is ten dollars, deal. The middle-aged monk hurriedly grabbed Chen Feng.

So a piece of 10,000-year-old iron essence worth tens of thousands of magic crystals arrived in the Immortal Tower again, and then it was melted to fill the gap.

Then Chen Feng pretended to look at it again, and soon received a message from the tower: "The others are all garbage, nothing to look at." ”

So Chen Feng broke away from the other party's enthusiastic palm, and then walked to another small stall.

"I said, Brother Chen, what kind of things did you buy just now, I think it's very ordinary. Tie Changkong couldn't help but ask.

"Hehe, it's very ordinary, it's boring to come out to play anyway, and besides, I can't spend a lot of magic crystals on my body, and I buy everything I like when I see it." Chen Feng said with a smile.

Tie Changkong and Shangguan Yun were also observing when Chen Feng was shopping, and they didn't see what these two treasures were, so they shook their heads and walked away.

Only Qin Long followed Chen Feng closely, and in Qin Long's opinion, Chen Feng was the richest of the three.

"These demon cores are not bad. Chen Feng looked at the jade boxes in front of him and said.

"Of course, when you look at the little brother, you will know the goods, and this is all left by the big demon. The speaker was a lean man of about thirty years old, and his eyes flashed with a glimmer of light from time to time. Looks savvy.

"Yes, they are all demon cores left by the big demon, two of them survived a thunderstorm, and the remaining three are very ordinary, but it's good to give them to your little pet. Tower said.

"Tsk, demon core, this is a good thing, this person actually took it out and sold it. Chen Feng said with a smile.

"If you keep it and you can't refine it, of course you have to sell it. Ta said lightly.

"I want all of your demon cores, make a price. Chen Feng said with a smile.

Speaking of which, these demon cores are indeed good things, of course, this is also for some people, for most monks, these demon cores have no effect at all except for selling, and demon beasts can devour and refine, but most human monks do not have this ability.

Only a very small number of monks can refine the demon core, or use the demon core to refine the pill and refine the magic weapon.

If it were in the outside world, these demon cores could indeed be sold for a good price, but it was different for the monks in the Immortal Mountain, because there were too few monks who could use the demon cores, and there was not even a single person in the entire Lightning City.

So seeing that someone wanted to buy the demon core, this lean monk was happy and entangled, this person also knew the value of the demon core, but he also knew that the locals would not Lang Fei Ling Stone to buy it.

And this outsider is different, but this monk is entangled in how to make a price, and he is not happy from the bottom of his heart if the price is low, anyway, these demon cores are not blown by the wind, but they are obtained at the risk of their lives, and if the price is high, the other party will not buy it, it will be even worse.

"Is this this?" said the lean monk's face was embarrassed.

"I wonder what price the little brother is willing to pay?" the lean monk suddenly asked rhetorically.

"Hehe, you are the seller, of course you made the offer. Chen Feng said with a smile.

"You also know the price of the demon core, and I won't ask for more, a thousand magic crystals. The lean monk gritted his teeth.

It is indeed not expensive, a thousand magic crystals and a demon core can be said to be very cheap, especially since there are two demon cores that have survived the thunder tribulation, if they are sold to useful monks, then the value will be great.

"The price is reasonable, but you also know that if I don't buy it, you won't be able to sell these demon cores. Chen Feng said with a smile, although he had enough magic crystals on his body, he would not spend them at will.

"If you want them all, five or four thousand magic crystals. The lean monk thought for a moment and said.

"Three thousand. Chen Feng made a faint counteroffer.

"Three thousand five. ”

"Deal. ”

When the demon core fell into the Immortal Tower, the purple electric silver light Jiao jumped up excitedly, if it weren't for Chen Feng's concerns, I'm afraid he would have opened his mouth and swallowed it directly.

"Two of them are yours. Chen Feng said lightly, and at the same time, the two demon cores that had survived the thunder tribulation flew in front of the Purple Electric Silver Light Jiao.

"By the way, who of you still has a demon core here?" Chen Feng asked with a smile.

I don't know when this kind of good opportunity will be encountered, Chen Feng naturally wants to loot it, the two demon beasts Zidian and Four Ears want to advance and improve their strength, devouring the demon core is the most haode option, not to mention that Chen Feng himself can absorb and refine the demon core.

"Well, if you want, I'll give you some more in a few days. The lean monk said hurriedly.

"Okay, I'll come back in a few days, no matter how many demon cores you can get, I'll take them all. Chen Feng said proudly.

For the next whole day, Chen Feng and the three of them did not leave this exchange square, especially Chen Feng, because there was a tower secretly directing, this time they gained a lot, but Chen Feng bought the most rare ores and demon cores, in addition to this, Chen Feng even bought a few big demon bodies and the essence blood of the big demon.

At the end of the day, the most beneficial thing is the purple electric silver light Jiao and the immortal tower hidden in the immortal tower, especially the immortal pagoda swallowed no less than ten pieces of rare ore, each of these ores is worth tens of thousands of magic crystals, and even a small piece of iron source mother essence is worth 300,000 magic crystals, zuihou was bought by Chen Feng for twenty magic crystals, and he laughed at the time of Ta Le's haha.

The look of shock on Qin Long's face, who was following Chen Feng and Chen Feng, had never disappeared, and he felt his muscles stiff and his eyes were sour at the end of the day, which was caused by maintaining an expression for a long time.

Before leaving, Chen Feng bought another treasure, which was a piece of hard scale armor, according to the tower, this was a piece of Jiaolong's scale armor, and it was also the scale armor of a Jiaolong who had survived five thunder tribulations.

This time, Chen Feng was really bleeding in order to buy this scale armor, and he spent 10,000 magic crystals, just like that, if the other party was not anxiously waiting for the need for magic crystals, he would not have sold them to Chen Feng.

"This scale armor is good, you can refine a defensive magic weapon. Although it cost some magic crystals, Chen Feng was still very satisfied, after all, this kind of thing usually can't be bought with more spirit stones.

"Brother Chen, it seems that you have gained a lot this time. Tie Changkong asked with a smile.

"I just bought something weird. Chen Feng said with a smile, it was obvious that Tie Changkong and Shangguan Yun had also gained something.

After returning to his residence, Chen Feng continued to cultivate, and this night Chen Feng devoured a huge tree again, and the wood essence in his body became even stronger, but he still did not break through, but Chen Feng already felt that it was not far from breaking through.

For the next three days, Chen Feng continued to go to the Exchange Square, and Zuihou bought ten more demon cores, which stopped.

thought that Chen Feng's cultivation had really reached a critical point, and he began to rush through the level.

On this day, two giant trees were devoured into pieces by Chen Feng, and the true qi in the body finally rolled and exploded, according to the record above the Immortal True Scripture, the true qi in the body began to launch an impact on a mysterious place, Chen Feng knew that this place was the Wood Cave in the Five Elements Cave.

After a day of continuous impact, the Wood Cave was finally impacted, first the powerful Wood Vitality erupted from the Wood Cave, spreading all over Chen Feng's body, making Chen Feng feel all kinds of mysteries of the power of the Wood, and then the Wood Cave shook violently, a powerful suction force burst out, and most of the immortal true qi in the body was instantly absorbed.

"Good fellow, I'm glad I was prepared. Chen Feng's heart moved, and a demon core appeared in the palm of his hand.

The attribute of this demon core is the attribute of wood, which Chen Feng had just purchased, and it was just used for cultivation.

Moreover, the big demon who left this demon core did not survive the thunder tribulation, and Chen Feng absorbed it more easily.

Chen Feng, who was cultivating, didn't know that the big purchases of the three of them in the past few days had already attracted the attention of some monks in Lightning City, for these people, there was no doubt that Chen Feng and the three of them were a treasure trove of movement, limited to the city rules, everyone did not do anything to the three of them in the city, but once Chen Feng and the three of them left Lightning City, it would be difficult to say.

When Chen Feng rushed through the pass, Tie Changkong and Shangguan Yun continued to walk around Lightning City under the leadership of Qin Long, trying to find other monks who came in from outside, but Tie Changkong and the two were soon disappointed, according to the news they received, there were indeed monks from outside who came some time ago, but they only stayed in Lightning City for a few days before leaving.

"By the way, is your city lord of Lightning City in the city?" Tie Changkong asked Qin Long.

"Our city lord Shenlong can't see the end of the head, and even the sandstorm outside the city can be stopped, and I heard that he often goes to other places to take risks. As soon as he mentioned the Lightning City City Lord, Qin Long's eyes began to glow.

Tie Changkong and Shangguan Yun muttered secretly, if this city lord was really a human immortal, then blocking a sandstorm of this level would not be a matter of turning over their hands.

When Tie Changkong and the two came back from a day of shopping, Chen Feng was sitting in the courtyard a little strangely.

"What's the matter, Brother Chen, is something wrong?" Tie Changkong asked curiously.

"It's nothing, it's just that I just have some experience in cultivating. A smile appeared on Chen Feng's face.

In fact, Chen Feng was smiling bitterly in his heart, the cultivation just now, the demon core in his hand was absorbed by Chen Feng cleanly, and the Wood Acupoint stabilized, and Chen Feng's cultivation also increased significantly.
