At night, the bright moonlight sprinkled all over this mountain forest.

In the forest behind the mountains, Lei Biao sat on a stone, and he took out the five-grade Ganoderma lucidum that he had auctioned at the Chamber of Commerce Exchange a few days ago from his arms.

Five-grade Ganoderma lucidum, the fragrance wafting out makes people feel refreshed, Ganoderma lucidum emits a faint light in the night, Lei Biao takes it in his hand and looks at it carefully.

Lei Biao took out the black wood, poured the spiritual power of his body into the black wood, and put the five-grade lingzhi and a first-grade beast core on the black wood, and with the continuous infusion of spiritual power, the lingzhi refined on the black wood turned into a wisp of smoke and was absorbed by the black wood.

"Whew!"

Lei Biao's eyes were shocked, this black wood actually swallowed the lingzhi? Looking at the disappeared black wood, Lei Biao was puzzled.

Although he was puzzled, Lei Biao did not stop the infusion of spiritual power, and suddenly, he saw a red light emitted from the black wood, and the light lasted only a few seconds.

From the disappearance of Lingzhi just now to the appearance of the Red Yuan Dan now, Lei Biao was quite surprised when he recalled this scene, and he was also surprised by the strange mystery of the black wood.

Lei Biao picked up two Yuan Dan, leaving a trace of warmth, from this warmth, Lei Biao could feel that the red Yuan Dan contained extremely pure spiritual power, and the quality of the refined Yuan Dan also reached the third grade.

The Sanpin Yuan Dan has a multiplier effect on cultivators below the ninth level of the body building, so many family forces do not hesitate to spend a lot of money to buy it, thus helping the younger generation of their family to grow up rapidly.

However, the Sanpin Yuan Dan does not have much effect on breaking through the human venerable vein, so the spiritual power required to break through the human venerable vein is very huge, and although the spiritual power of the Sanpin Yuan Dan is pure, the spiritual power contained in it is still insufficient to supply the consumption when the human venerable vein breaks through.

If you can refine the Four-Rank Yuan Dan, it will be of great help to break through the human venerable lineage. At this moment, although Lei Biao has just entered the Nine Layers of the Body, he is also very eager to break through the human venerable vein, so that he will also have a bargaining chip in the fire wolf hunt in the near future.

However, looking at Muyang City, there are probably very few people who can refine such a pure four-grade Yuan Dan, and these people who can refine the Yuan Dan are often arrogant, and they are not a certain force that can influence them.

Lei Biao looked at the red three-grade Yuan Dan in his hand, and was a little frustrated, after all, the three-grade Yuan Dan at this time was not of much help to him when he first entered the ninth level of the body.

So, Lei Biao thought of the Chamber of Commerce Exchange again, if he took this three-grade Yuan Dan to the Chamber of Commerce Exchange to exchange for some higher-grade Ganoderma lucidum, maybe there was a chance to refine the four-grade Yuan Dan.

Early the next morning, Lei Biao went out early to the Wuyu Zhen Chamber of Commerce Exchange. In order to hide his identity and avoid other troubles, Lei Biao bought a black coat and hat and wrapped himself tightly.

From the main entrance of the attic, Lei Biao cautiously walked inside.

Passing through a dimly lit hallway, a cold feeling came over the depths of the hallway, and at the end of the hallway was a room with a yellow light with a hidden door. Presumably this is the place for trading, Lei Biao gently pushed the door open and entered the room.

In the room, it was still dim and gloomy under the yellow light, and in the middle of the house sat a middle-aged man, this middle-aged man Lei Biao was no stranger, it was the man who got the five-grade Lingzhi in the last auction.

"You're here again, what do you have to trade this time?" the middle-aged man asked.

With the last experience, this time Lei Biao sat down very calmly, and took out a white porcelain jade bottle from his chest, and in the bottle, there were two dark red three-grade Yuan Dan, these two Yuan Dan were the Yuan Dan that Lei Biao had made by refining the five-grade Lingzhi from black wood not long ago.

"In the bottle are two third-grade Yuan Dan, which are not only helpful for the cultivation of the ninth level of the body, but also can strengthen the body and bones. Lei Biao put the bottle in front of the middle-aged man, his voice was a little low, obviously this was completely different from Lei Biao's own original voice.

"Please wait a moment, we need to confirm this Yuan Dan. The middle-aged man replied with a smile.

The middle-aged man picked up the jade bottle, pressed his hand on the secret passage in the room, and a stone door slowly rose, and the middle-aged man walked in through the raised stone door, leaving only Lei Biao in the room.

Lei Biao glanced at the figure of the middle-aged man leaving, presumably it was the person in charge of the exchange in Shimen who wanted to confirm this Yuan Dan, after all, this was a transaction, so Lei Biao didn't care about this, they just went to confirm it if they wanted to confirm it.

The old man in the stone gate poured out the Yuan Dan from the jade bottle, his eyes were shocked. This Yuan Dan is so pure, it is the first time he has seen it, it seems that this mysterious person has an extraordinary background. Let go of the entire Muyang City, this level of Yuan Dan is by no means something that can be refined by a certain family, otherwise the situation of the four major families in Muyang City will be broken.

The middle-aged man looked at the old man so surprised, and felt a little sorry for the fact that he had neglected this mysterious man just now.

"I'll go out with you, I want to see who this mysterious man is. The old man said to the middle-aged man.

The stone gate rose again, and out of the middle-aged man was an old man who was nearly half a hundred years old.

This three-grade Yuan Dan, the spiritual power is pure, it is indeed very suitable for the cultivation of the body building vein, the foundation building effect is excellent, and it also has the effect of quenching the body, therefore, this three-grade Yuan Dan is also very valuable, I don't know what you want to exchange?

Lei Biao looked at the old man in front of him, sure enough, he was a knowledgeable guy, the main thing in charge of this exchange did have some ability, and after some contemplation, he said: "Seven strains of five-grade Ganoderma lucidum, three plants of six-grade Ganoderma lucidum." ”

"Your Excellency, the Sanpin Yuan Dan is only an excellent benefit for the cultivation of the body building vein, but it is not of much use for cultivators above the human venerable vein, which Your Excellency must naturally know. So, your requirements are a bit high. The old man responded.

"How about three fifth-grade Ganoderma lucidum, two six-grade Ganoderma lucidum?"

"Five plants and five products, two plants and six products. Lei Biao said in a deep voice.

"Four plants and five products, two plants and six products, if you can't accept it, this is also our regret. The old man sighed, presumably this was his bottom line.

"Yes, deal. ”

Lei Biao's hands were slightly sweating, and he was also very happy in his heart, after all, these two Yuan Dan could be refined with just one five-grade Ganoderma lucidum, and they were also exchanged for two six-grade Ganoderma lucidum, this transaction was also worth it, although he didn't know if the old man in front of him was lowering the price, but since this trip was not in vain, it was worth it.

Since the two sides had reached an agreement, Lei Biao waited in the room, and in less than a few minutes, he saw the middle-aged man holding two delicate boxes in his hands, Lei Biao opened the box, and four purple Ganoderma lucidum and two brownish-yellow Ganoderma lucidum were neatly placed in the box.

After some inspection, Lei Biao also arched his hand with satisfaction, casually put the box in his arms, turned around and left.

As Lei Biao left, the old man held the jade bottle, and the pure aroma wafted out of the jade bottle, and the old man was obviously very satisfied with the deal.

The middle-aged man looked at the old man suspiciously, obviously for the exchange of two third-grade Yuan Dan for four fifth-grade lingzhi and two sixth-grade lingzhi, is it worth the transaction?

You don't understand this, these two Yuan Dan, but the old man, I have seen the purest Yuan Dan in Muyang City for so many years, I am afraid that this mysterious person's identity is not simple, and he can refine such a pure Yuan Dan.

"First, we naturally don't lose money on this transaction, for the four major families in Muyang City, if we auction these two Yuan Dan, naturally, the four major families will be willing to pay a high price to buy this Yuan Dan.

Second, let's be a good favor and establish a good relationship of trust with this mysterious person, and if this mysterious person has any treasures that need to be auctioned in the future, he will naturally come to us. The old man said with a satisfied smile on his face.

"So, do you need to investigate the origin of that mysterious man?" said the middle-aged man lightly.

"Don't you still know the rules? This mysterious person is naturally also our guest, since he is a guest, naturally these things are kept secret, otherwise, these mysterious people will find helpers to kill them back, and in the future, in Muyang City, will we still have a foothold? Not to mention that you can't afford to offend, even if our entire Chamber of Commerce Exchange does not dare to offend easily. ”

After the old man's scolding, he saw that the middle-aged man didn't dare to speak anymore, so he nodded quickly.

The old man picked up the jade bottle, ignored the middle-aged man, and left through the stone gate
