This similar exchange also exists in Yanluo Sect, and there are also a lot of strange things in it, which are said to be treasures, but it is difficult to distinguish the real from the fake.

The disciples of the sect can buy and sell items in it, and since it is a transaction within the sect, there is no such thing as killing people and looting treasures, so the business is very hot.

"Hopefully there's some useful treasure here. Han Feng muttered in a low voice and walked through the door.

Guarding the exchange was a lean old man, his eyes were shining, his name was the dragon of the sea, he had always been shrewd, no one could bluff him, and no one wanted to steal anything here.

"Elder. Han Feng bowed.

Hai Zhonglong looked at Han Feng for a while, and then said, "Young man, you know the rules here, right? ”

The rules are strict, so that no one dares to break them.

Han Feng nodded and said, "Don't worry, Elder, I'm not that kind of person." Then he went inside.

The first floor is a lobby that occupies a large area, and the fragrance of elixirs and various spirit fruits is mixed together, making people feel really extraordinary.

Passing by a lot of extraordinary treasures, Han Feng's eyes lit up.

The cloud mist flower is the appearance of a flower as a whole, but there are clouds and mist around it, and the pure aura is emanated, which shows that the spiritual power is full.

Han Feng wanted to buy this flower, but when he saw the price, he stopped again.

A cloud mist flower costs four hundred spirit stones, and although he now has about a thousand spirit stones, he is reluctant to spend so many.

Walking further on, I saw a lot of other herbs and the like.

Purple Yuan Flower, Green Devil Vine, Black Heart Grass, etc., are all elixirs with sufficient aura, and Han Feng is quite excited to see it, if he can absorb the aura of these elixirs, then his cultivation will definitely improve a lot.

But looking at the price again, he shook his head helplessly. It's all too expensive.

About a thousand spirit stones, I thought it was a lot, but in this exchange, I couldn't buy a few things.

After walking around for more than half an hour, when he passed by the place where spiritual weapons were traded, Han Feng didn't look at it much, and now that he had the Seven Star Knife, he really couldn't look down on those spiritual weapons.

When he arrived at the area where the exercises were sold, Han Feng picked up the ancient books and looked through them, but he was a little disappointed. It turns out that the ancient books here record the basic combat skills of controlling the aura, which are of little use to the current Han Feng.

He continued to look through some ancient books, but Han Feng's eyes lit up, and he saw an ancient book with the cover written: Aura Potion.

The curious Han Feng opened the ancient book and found that it was recorded how to make the aura potion.

Han Feng was very puzzled as to why the Southern Heavenly Sect would put this cultivation resource refining method on the bright side. The aura potion is similar to the spirit stone, which can absorb the aura in it and can also be exchanged for other things.

But the refining method of this potion is usually a secret that is not passed on, and now this book is placed here, could it be that the Nantian Sect is not afraid that the disciples will learn it?

Then Han Feng glanced at the price of the book again, thirty spirit stones.

"Thirty spirit stones are a bit too cheap, could it be that the method recorded in this book is fake, or is it incomplete?" Han Feng wondered in his heart.

At this time, Hai Zhonglong, the caretaker of the exchange, happened to pass by, and when he saw Han Feng holding the book in a daze, he couldn't help but ask curiously: "Young man, do you want to learn the refining method of the aura potion?"

"Yes, senior," Han Feng replied, "but this potion method is only worth thirty spirit stones?"

"Nobody buys it so cheaply. ”

"Why doesn't anyone buy it?"

"It's useless for ordinary people to buy it, this method of refining aura potions requires earth light, and at the very least, it also needs to burn the black light mined in the iron ore vein, but the black light is so easy to encounter. Our Southern Heavenly Sect only has a black light. ”

It is rumored that there is an aurora in the polar regions, also known as the earth light, which has a shape but no substance, and can be contained in a bottle. There are many ancient records that you can use the light to help refine the elixir and other things.

After listening to the words of the dragon in the sea, Han Feng thought for a moment and said directly: "Then I will buy it, maybe I can find something else to replace the black light." ”

Anyway, it's only thirty spirit stones, and even if you can't find the black light now, it's good to master the method.

And the golden beads in the dantian, it can emit golden light, and it seems to have the effect of earth light, maybe you can try it with that golden light.

Han Feng took out thirty spirit stones, handed them to the sea dragon, and bought the books on the aura potion.

"Pick for yourself, and remember to take care of your hands. After taking the spirit stone, the sea dragon walked away.

After the sea dragon left, Han Feng was already eager to try it in his heart, wanting to see if he could refine the aura potion. If you can refine it, you can make a lot of money.

As soon as he turned around, Han Feng suddenly felt the golden beads in the dantian vibrate.

"Mo Fei, what's the good thing?" When Han Feng encountered the Seven Star Sword before, the golden beads of the dantian sent out a slight vibration.

This time it was the same situation again, Han Feng had already guessed that the golden bead could identify treasures.

Han Feng's eyes swept over every treasure on the wooden shelf, and when he saw a white jade bottle, there was a vibration in the dantian again.

"Let me see how different you are. Han Feng reached out and picked up the white jade bottle.

The white jade bottle is the size of a palm, the appearance is as white as mutton fat, and there are a few strange runes painted on it, which is nothing strange at first glance.

But Han Feng knew that many treasures had an average appearance and could not be judged only by their appearance. For example, the Seven Star Knife looks very ordinary, but in fact, it has the Heaven and Earth Forging Technique.

After looking at the introduction on the booklet next to it, this white jade bottle actually has the effect of a Qiankun bag, and it has a world of its own, which can hold dozens of buckets of water.

"You bead, is it because of its large space that you fancy it?" Han Feng said silently in his heart.

It seemed that he sensed Han Feng's thoughts, and the golden beads in the dantian vibrated again, which could be regarded as an answer.

"Well, I believe you. Han Feng decided to buy the white jade bottle, but after seeing the price, he couldn't help but be a little stunned.

1,200 spirit stones, which is simply sky-high.

"I can't seem to afford that. Han Feng shook his head, but the golden beads still trembled.

I don't know when, the dragon in the sea appeared behind Han Feng again, and said with a smile: "Young man, do you want to buy this bottle?"

He was so elusive that he didn't make a sound.

Han Feng said: "Elder, I want to buy it, but it's a bit expensive, can it be cheaper?"

"There is space in this white jade bottle, and one thousand two hundred spirit stones are cheap enough, and they can't be cheaper. ”

"This ......"

"How many spirit stones do you have?"

"I only have a thousand, a little more, but if I want to stay, I can only take a thousand. ”

The sea dragon touched his chin and said, "Maybe you can make it up with something else?"

Han Feng thought for a moment and took out another bottle from the Qiankun bag, one of those bottles that contained poison.
