Chapter 248: Wood Cave

"Hahaha, what a bullshit black dragon stone, this guy is just fooling around, this is basically a piece of ten thousand year old iron essence, but there is one thing this guy said is right, that is, this piece of iron essence can indeed be made into a treasure." Tower laughed.

"Is it useful to you?" Chen Feng asked.

"Of course it is useful."

"That's good." Chen Feng nodded, and then asked: "How much is this black dragon stone?"

"Hahaha, I really met a sucker today. I didn't expect this silly boy to be so silly, but he is also silly and cute, hahaha." The middle-aged monk was so happy.

"This black dragon stone is worth 10,000, no no no, 1,000, no no no, 100 magic crystals." The middle-aged monk said while looking at Chen Feng's face.

"It's still 10 magic crystals. I say, uncle, you must be honest in doing business. Why do you keep asking for a random price? Forget it, I'll go to other places to have a look." Chen Feng shook his head and said.

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

So a piece of ten thousand year old iron essence worth tens of thousands of magic crystals went back to the Longevity Tower, and then was melted to fill the gap.

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

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

"Brother Chen, what are those things you just bought? I think they are very ordinary." Tie Changkong couldn't help asking.

"Haha, they are very ordinary. Anyway, it's boring to go out to play. Besides, I have too many magic crystals to spend. I buy them all I like." Chen Feng said with a smile.

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

Only Qin Long followed Chen Feng closely. In Qin Long's opinion, Chen Feng was the richest among the three.

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

"Of course, I know what's good, little brother. These are all left by big monsters." The man who spoke was a lean man in his thirties, with a gleam of light in his eyes from time to time. He looked very smart.

"Yes, they are all monster cores left by big monsters. Two of them have survived a thunder tribulation, and the remaining three are very ordinary, but they are good for your little pet to take." Ta said.

"Tsk tsk, monster cores, this is a good thing, this person actually took it out for sale." Chen Feng laughed.

"I can't refine it if I keep it, so of course I have to sell it." Ta said lightly.

"I want all your monster cores, name a price." Chen Feng laughed.

Speaking of which, these monster cores are indeed good things, of course, this is only for some people. For most cultivators, these monster cores have no use except selling them. Monster beasts can swallow and refine them, but most human cultivators don't have this ability.

Only a very small number of cultivators can refine monster cores, or use monster cores to make pills and magic weapons.

If it were in the outside world, these demon cores could indeed be sold at a good price, but it was different for the cultivators in the fairy mountain, because there were too few cultivators who could use demon cores, and there was not even one in the entire Lightning City.

So when he saw someone wanted to buy demon cores, the thin cultivator was both happy and entangled. He knew the value of demon cores, but he also knew that locals would not waste spiritual stones to buy them.

This outsider was different, but this cultivator was entangled in how to make an offer. If the offer was too low, he would not be happy from the bottom of his heart. After all, these demon cores were not blown by the wind, but were obtained by himself at the risk of his life. If the offer was too high, the other party would not buy them, which would be even worse.

"This?" The thin cultivator looked embarrassed.

"I wonder what price the little brother is willing to offer?" The thin cultivator suddenly asked back.

"Haha, you are the seller, of course you make the offer." Chen Feng smiled.

"You also know the price of demon cores, and I won't ask for more. One is one thousand magic crystals." The thin cultivator gritted his teeth and said.

It is indeed not expensive. One thousand magic crystals for one 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 cultivators, they will be of great value.

"The price is indeed reasonable, but you also know that if I don't buy them, you can't sell these demon cores." Chen Feng said with a smile. Although he has enough magic crystals on him, he will not spend them casually.

"If you want all of them, five will cost four thousand magic crystals." The thin cultivator thought for a while and said.

"Three thousand." Chen Feng bargained lightly.

"Three thousand and five."

"Deal."

When the demon core fell into the Longevity Tower, the Purple Lightning Silver Light Jiao jumped up excitedly. If it hadn't been for Chen Feng's concern, it would have opened its mouth and swallowed it directly.

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

"By the way, who here has demon cores?" Chen Feng asked with a smile.

It was unknown when such a good opportunity would come, so Chen Feng naturally had to plunder it. If the two monsters, Zidian and Sier, wanted to advance and improve their strength, swallowing the monster core was the best choice. Besides, Chen Feng himself could absorb and refine the monster core.

"If you want this, I can provide you with some more in a few days." The thin monk said hurriedly.

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

Then Chen Feng and the other two did not leave the exchange square for the whole day, especially Chen Feng, because the tower was secretly guiding him, and he had a great harvest this time. However, Chen Feng bought the most rare ores and monster cores. In addition, Chen Feng even bought the bodies and blood essence of several big monsters.

At the end of the day, the most benefited were the purple lightning silver light dragon and the Changsheng Tower hiding in the Changsheng Tower, especially the Changsheng Tower, which swallowed no less than ten rare ores, each of which was worth tens of thousands of magic crystals. There was even a small piece of iron source mother essence worth 300,000 magic crystals, which was finally bought by Chen Feng for 20 magic crystals, which made the tower laugh.

Qin Long, who was following Chen Feng, had never lost the shock on his face. He felt stiff muscles and sore eyes all day long, which was caused by keeping the same expression for a long time.

Before leaving, Chen Feng bought another treasure, a piece of hard scale armor. According to the tower, it was a dragon scale armor, and it was a dragon scale armor that had survived five thunder tribulations.

This time, Chen Feng really spent a lot of money to buy this piece of scale armor. He spent a full 10,000 magic crystals. Even so, if the other party was not in a hurry to need magic crystals, he would not sell it to Chen Feng.

"This piece of scale armor is good. It can be used to refine a defensive magic weapon." Although he spent some magic crystals, Chen Feng was still very satisfied. After all, this kind of thing can't be bought no matter how many spirit stones he spends.

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

"I just bought some strange things." Chen Feng smiled. It was obvious that Tie Changkong and Shangguan Yun also gained something.

After returning to his residence, Chen Feng continued to practice. This night, Chen Feng devoured a huge tree again. The wood essence in his body became more concentrated, but he still did not break through. However, Chen Feng already felt that he was not far from breaking through.

For the next three days, Chen Feng continued to go to the exchange square, and finally bought ten more demon cores before he stopped.

It was thought that Chen Feng's cultivation had really reached a critical point and began to break through.

On this day, two giant trees were devoured by Chen Feng and turned into pieces. The true qi in his body finally burst out. According to the record in the Changsheng Zhenjing, the true qi in his body began to attack a mysterious place. Chen Feng knew that this place was the Wood Cave among the Five Elements Caves.

After a day of continuous attack, the Wood Cave was finally opened. First, the strong vitality of wood erupted from the Wood Cave and spread throughout Chen Feng's body, allowing Chen Feng to experience the mysteries of wood power. Then the Wood Cave shook violently, and a strong suction force burst out, and more than half of the longevity true qi in his body was instantly absorbed.

"Good guy, fortunately I was prepared." Chen Feng's mind moved, and a demon core appeared in his palm.

The attribute of this demon core is the attribute of wood. Chen Feng just bought it back and it was just right for cultivation.

Moreover, the big demon who left this demon core did not survive the thunder tribulation, so it was easier for Chen Feng to absorb it.

Chen Feng, who was practicing, didn't know that the three people's large purchases in the past few days had already attracted the attention of some cultivators in Lightning City. For these people, Chen Feng and the other two were undoubtedly a mobile treasure house. Due to the city rules, no one took action against the three people in the city, but once Chen Feng and the other two left Lightning City, it would be hard to say.

When Chen Feng was breaking through the barrier, Tie Changkong and Shangguan Yun continued to walk around Lightning City under the leadership of Qin Long, trying to find other cultivators coming in from outside, but Tie Changkong and the others were soon disappointed. According to the news, some cultivators from outside did come some time ago, but they only stayed in Lightning City for a few days and then left.

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

"Our city lord is like a dragon that can't be seen from head to tail. He can even block the sandstorm outside the city. I heard that he often goes to other places for adventure." Qin Long's eyes began to light up when he mentioned the city lord of Lightning City.

Tie Changkong and Shangguan Yun whispered secretly that if this city lord was really a human immortal, then blocking this level of sandstorm would not be a matter of turning his hand.

When Tie Changkong and the others came back from a day of strolling, Chen Feng was sitting in the yard in a strange manner.

"What's wrong, brother Chen? Did something happen?" Tie Changkong asked curiously.

"Nothing, I just gained some experience from practicing." Chen Feng smiled.

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