Chapter 180

Soon, Chen Feng and others were disappointed.

The cave here is very spacious. I don't know what formula is used, which can directly reflect the external sunlight. Moreover, the walls are densely inlaid with fist sized night pearls. These things are priceless rare treasures in the secular world, but they are only put here as simple decorative articles.

In the cave, just like outside, the air is clear and the space is thorough, but Chen Feng and Chen Feng began to wander from the foot of the mountain to the hillside. Chen Feng felt a little helpless.

Although the things here are complete, there is nothing that Chen Feng can see. Although occasionally there are some rare herbs, some human level pills, or some four or five magic weapons or robes, which are good for these external disciples, they are useless for Chen Feng. If he has a treasure, will he care about these magic weapons.

"It seems that we will be disappointed again today." Chen Feng shook his head and said that although Chen Feng had just seen someone selling the Dharma array, the power of the Dharma array could not even stop the inner disciples.

However, when approaching the top of the mountain, Chen Feng finally met something that interested him, a demon core.

"What is this?" Chen Feng pointed to a crystal in front of him and asked. In fact, what Chen Feng cares about is not the crystal, but the things sealed in the crystal.

The things in the crystal are half fist big, red and round. At a glance, they seem to be solidified liquid.

Just now, Chen Feng sensed a strong breath, which locked his eyes on the things in front of him.

Who knows that after Chen Feng asked, the other party didn't respond. It seems that they don't want to talk to Chen Feng at all.

"Ask you, are you deaf?" Luta said loudly.

"Ask what, can you afford it?" A young man sitting behind a table glanced at Chen Feng and said with a disdain.

"Oh, really? I despise our external disciples." Chen Feng sneered and took the crystal in his hand as soon as he reached out.

Chen Feng's behavior immediately became hot. The young man immediately patted the table and stood up to attack. However, after seeing Chen Feng's clothes, his face immediately showed a surprised expression, and then piled up a smile again. Chen Feng was surprised at the speed of his face change.

"Hehe, what do you like?" The young man asked with a smile.

This is a monk on the fourth floor of the secret realm. He has reached the point of slight cultivation. He is also an inner disciple. Chen Feng naturally understands why this man changes his face so quickly, all because of their clothes.

He was wearing a five level robe with a five level sword hanging around his waist. Although his cultivation was not very high, he had shocked the young man secretly.

"These two must have strong backstage?" The young man thought to himself.

"I just asked what this is?" Chen Feng asked, playing with the crystal in his hand.

"The two younger martial brothers really have eyes. What is sealed in this crystal is the demon core of a big demon." The young man said at once.

"The demon core of the big demon." Chen Feng was stunned. He thought of the essence of the tree in the black source mountains. At that time, he absorbed some of the essence of the tree essence, which would lead to a rapid development. At that time, the tree essence seemed to have passed through the thunder robbery, that is, the strength of the big monster, and the essence of the essence of the tree is equivalent to the monster of the big monster.

"This is a good thing." Chen Feng said secretly.

"Tower, is this the demon core of the big demon?" Chen Feng asked secretly.

"Yes, but the essence has been largely lost, leaving less than half of its strength." The tower answered quickly.

"Less than half, it's a great monster's body essence, it's a good stuff, and I don't know why the other party is going to sell it. Yes, if I buy it, what's the use?" Chen Feng asked again.

"Yes, you can absorb the power of this evil core. This is the essence of a big demon whole body. After refining, it can greatly enhance its strength." The tower said faintly.

"Then why doesn't this man refine and absorb?" Chen Feng has some doubts.

"You think this demon core can be absorbed and refined by human friars. It's not that simple. You can absorb it because you have cultivated the eternal life Sutra. These ordinary friars want to refine this demon core. It's just a dream." The tower disdained.

"Human friars are difficult to refine, so can other demons refine this demon core?" Chen Feng suddenly moved in his heart and asked.

"The same demon family, naturally." TA said simply.

"Excuse me, what is the demon core of the big demon?" Chen Feng looked

"Hehe, I don't know. I got this demon core by chance." The young man had a smile on his face and spoke politely.

Originally, the young man wanted to stay, but later he found that he couldn't refine and absorb it, so he had no choice but to exchange it for something.

"I'll take the demon core. Make an offer." Chen Feng smiled.

"This?" As soon as Chen Feng wanted to buy it, the young man's eyes immediately began to turn.

"You don't want to pay a high price. To tell you the truth, this demon core doesn't even have half the power." Chen Feng said with a smile.

"Well, I want to exchange a flying sword of six magic weapon level." The young man gritted his teeth and said.

"Ha ha, your appetite is not small. Well, I'm only willing to produce a flying sword of five magic weapon level." Chen Feng stretched out his hand and a flying sword kept spinning in the middle of his palm.

"Wupin flying sword."

Looking at the flying sword in Chen Feng's hand, the young man suddenly showed a hot look in his eyes.

"Well, it's a deal." The young man gritted his teeth.

As soon as Chen Feng waved his hand, the flying sword flew out and fell into each other's hands, and he quickly put the crystal away.

Then Chen Feng didn't stop, but separated a trace of divine consciousness into the longevity tower.

"Four ears, give you a good thing." Chen Feng's voice sounded in the longevity tower. The crystal just purchased split directly in front of the four eared monkey, and a powerful demon force was emitted from it.

"Eh, it's the demon core." Zidian Yinguang Jiao rushed over for the first time and wanted to swallow this demon core.

"Step back." Chen fengleng shouted. Zidian Yinguang Jiao immediately felt a shock to his soul and involuntarily retreated to one side.

"Four ears, you are a monster. You should be able to refine the demon core of this big demon?" Chen Feng asked.

"Can, can, can be refined." Four ears communicated with Chen Feng excitedly with divine knowledge, and looked at the demon core floating in front of him, jumping excitedly.

"Well, I'll give you this demon core. I hope you can improve one or two levels after refining. Then I'll let you out and show me the mountain guard." Chen Feng took back his divine knowledge after saying this.

The four eared monkey was still jumping around the demon core. Only Zidian Yinguang Jiao hummed a few times, but he didn't dare to say anything. He looked at the demon core with envy and went to sleep.

"Your boy gave the demon core to the little monkey." Tower was a little surprised.

"Yes, it's time for me to cultivate the long life Sutra with my heart. If I refine this demon core again, I'll be distracted. Besides, isn't it right for this kind of thing to be refined by demons?" Chen Feng smiled.

"This is the last cave. I don't know if there will be good things. This time I made a trip in vain." Ruta was a little dejected.

"Eh! There are so many metal ores in this layer?" As soon as he entered the cave, Chen Feng saw pieces of rare metal ores on the counter, on the ground and even on the wall.

"Tower, aren't you seriously damaged? There are many ores here. Do you think you can use them?" Chen Feng asked with a smile.

"Hum, what do you think of me? Do you think I'm a magic weapon or a treasure? How can this rubbish get into my eyes?" TA said with some annoyance.

"Then help me pick out some better metal ores." Chen Feng said.

"Why do you buy this? There's nothing good here." The tower said disdainfully.

"Be prepared. Store some metal ores in advance. When I have enough accomplishments in the future, I will practice the method of refining utensils." Chen Feng said faintly.

"Well, let me choose for you. Well, this is da Luo refined iron. The grade is good. I'll buy it."

"And the black ore is called black gold stone. It's also good. It's suitable for you. I'll buy it."

"There are also Star steel, black iron and refined steel here. Tut Tut, there is also a Tongling stone here. Although the grade is not high, it is also good."

"This is refined iron pulp, this is iron magic sand, and this piece of Moro stone."

"And..."

Listening to the tower constantly quoting metal ores, Chen Feng immediately came forward to ask the price, then haggled and bought. Soon, more than a dozen kinds of metal ores were loaded into the longevity tower.

"God, this is ziyao copper essence. How can there be such a thing here, boy? You should buy this ziyao copper essence if you don't take action." Suddenly, the sound of the tower fluctuated, some surprised, some excited, and some happy.

"What ziyao copper essence? Are you talking about this purple copper ore? I look very ordinary." Chen Feng looked at a purple copper lump with a big fist in the wall and asked.

"What copper ore? It's a good thing. It's very valuable even in the fairy world." TA couldn't help saying.

"No, you won't lie to me?" Chen Feng had some doubts, but began to plan to buy.

"Elder martial brother, please bring that copper ore here." Chen Feng pointed to the copper ore in front of him and said.

"Oh, you want to buy this ore?" The owner of this ore is a middle-aged man who looks kind and has five layers of secret territory. At this time, he is looking at Chen Feng curiously.

"Yes, I want to see." Chen Feng nodded.

"Yes, take it yourself." The middle-aged man smiled.

So Chen Feng came forward, stretched out his hand, didn't move, tried hard, still didn't move.

"Eh, it's so heavy." Chen Feng was surprised and began to gradually increase his strength. Finally, Chen Feng picked up the fist sized copper ore.
