Through Yang Feng's observation, we found that behind each tribal stall, there was such a small black room for secret transactions.

The decorations in the room are very simple, with only one table and two chairs.

A rune was engraved on the wall, but I don’t know if it was a ban on it.

The two sat down face to face, and the scar-faced man breathed a sigh of relief.

The scar-faced man opened the box again and saw a black crystal the size of a fist in it.

There are countless tiny holes on it, which look like honeycombs.

A trace of black mist emerged from the hole, looking a little mysterious.

The scar-faced man looked at the things in the box with a hot look and said, "Your quality is very good, it can be considered the best. You should be mostly magic crystals, or you can exchange things for things."

Yang Feng smiled and said, "You are really a human being. It is wise for me to come to you. Since this is the case, we will go straight to the point. I want three hundred magic crystals."

The scar-faced man said with a embarrassed look: "Three hundred magic crystals are a bit expensive, we will accept them for two hundred."

Yang Feng said in a deep voice: "Two hundred and eighty magic crystals!"

The scar-faced man shook his head and said, "There are the most two hundred magic crystals!"

The two bargained and finally confirmed two hundred and fifty magic crystals.

The scar-faced man waved his hand, took out a storage ring and handed it over.

Yang Feng took the storage ring and swept his spiritual sense.

There are a pile of black crystals inside, each of which is the size of a fist. You can see a trace of black gas inside in Liudong.

This thing is called magic crystal, which is the currency circulated by demon cultivators. It is similar to the immortal stones in the fairy world, but it contains very pure evil spirits.

That thing Yang Feng was the material from the storage bag of the demon fairy's corpse back then.

It costs some magic crystals to inquire about information, so Yang Feng sold this thing first in exchange for some magic crystals.

Yang Feng put away the storage ring and was overjoyed.

This thing is just the most inconspicuous piece of the countless precious materials in the magic fairy storage bag. It can actually sell more than 200 magic crystals, which is not bad.

I don’t know how much other materials are worth, and the value of the storage bag is beyond Yang Feng’s expectations.

The scar-faced man looked at Yang Feng with anticipation and said, "If you have other precious materials on you, it is better to sell them all to me when you go to find other sellers. You don't have to worry about the price. We have always had a very good reputation and will never disappoint you."

Yang Feng shook his head and said, "I discovered this thing by chance, where are there more."

The scar-faced man, hearing this, showed a look of disappointment on his face.

Yang Feng smiled and said, "Although I have nothing to sell to you, I want to buy something from you."

The scar-faced man asked happily: "What do you want to buy?"

Yang Feng said: "I want to buy some books from you!"

The scar-faced man was stunned, and then asked with a vigilant look: "What book?"

Yang Feng smiled and said, "Don't worry, what I want is not your secret technique, but your books such as humanities, geography, materials, and so on, preferably outside the Qingqing Grassland, or even outside the Mobei. You are a large tribe of the Qingqing Grassland, and there should be a lot of books in this regard."

Yang Feng had just walked along the way, and there were only various materials on the stalls and he didn't see a single book.

It’s no wonder that the grassland conference mainly trades various materials, and who would spend time collecting any classics?

Yang Feng wanted to collect various information, but this was the only way to do it.

"It turns out that if you want these classics, you can sell them to you, but these classics are all collected by our clan and the price is not cheap."

The scarred man relaxed when he heard this, then looked at Yang Feng deeply and said.

"As long as it is valuable classics, the more it is better." Yang Feng pointed at the desktop with his finger and said with a smile.

"Okay, please wait a moment here."

The scar-faced man stood up, turned around and walked out.

Half an hour later, Yang Feng left the tiger stall and a smile appeared on the corner of his mouth.

From the Tiger Clan, he obtained a lot of classics.

He just read it out and found that many of them were outside the green grassland, and some were information from Mobei, which was of great value.

Yang Feng did not stop and continued to move forward.

In a blink of an eye, most of the day passed.

It was already dark, and huge cages were hung everywhere in the trading area, and white fireflies were placed inside, emitting bright white light, making the lights shining on the trading area brightly.

As the night gets darker, the trading area becomes more lively.

Yang Feng walked over the stalls one by one, and was in a pretty good mood.

In the past half a day, he found two more ethnic groups, sold some materials, and bought some books about the Demon World.

The three ethnic groups Yang Feng chose were all large clans and bought a lot of information, which was far better than those of the Lizard clan’s books and materials.

He thought in his mind that he decided not to continue buying books for the time being.

First of all, the information he bought was almost enough, and the information of each ethnic group in the Qingqing Grassland was closed, and the books and materials stored in each ethnic group were almost the same, with many duplicates.

Moreover, at the grassland conference, buying classics everywhere is quite strange. If you do too much, it may attract the attention of those who are interested.

Yang Feng let go of his mind and looked at the goods at the stalls on both sides.

Along the way here, he studied various classics of the Lizard Clan and had some identification skills in the demon world. In addition, his spiritual sense was extremely powerful, so he soon discovered many good things.

"Hey, this is!"

He suddenly stopped in front of a stall, and a hint of excitement appeared in his eyes under the cloak.

The stall here is not very big. Most of them are spiritual herbs, ore materials, etc. There are two horns standing behind the stall, with fish scales on the face, which looks very similar to the alien race of fishmen.

"What do you like about this friend?" A fishman alien greeted warmly.

Yang Feng looked at a box in a corner of the stall, where dozens of translucent plants were placed. The leaves were transparent and thin like ice crystals, and the inner veins were clearly distributed.

He is very familiar with this grass, and it is the main material for refining Susha Pill, Ku Luohua.

These extremely precious materials in the fairy world are piled up there casually at this moment.

"How to sell these spiritual herbs?" Yang Feng pointed at the bitter flowers.

"Oh, do you want these ice crystal grasses? One of the three magic crystals."

The fishman alien said casually, as if he had gone away enthusiastically.

"Three Magic Crystals..." Yang Feng felt speechless.

Ku Luohua is a top spiritual herb in the fairy world and is of great value. Many times, even if there are fairy stones, it can't be bought. It's so cheap in the demon world.

"Ice Crystal Grass, I seem to have heard of this name..."

He felt aroused his heart and recalled the Lizard Clan classics he had read a few days ago. There was a book that seemed to mention this grass.

He thought about it for a moment and the vague memories in his mind soon became clear.

According to the book, this grass grows in cold and cold places. There is a bottomless swamp deep in the green grassland, and a large number of ice crystal grasses grow.

However, this ice crystal grass is useless to creatures in the demon world, so the book only briefly explained it and did not draw a figure. Otherwise, he would have recognized that the ice crystal grass was the bitter flower.

The effect of Ku Luohua is to dispel evil spirits. This thing is a harmful thing for creatures in the demon world, no wonder it is so cheap.

“Is that the only one?”

When Yang Feng thought of this, he suddenly realized it and asked.

After hearing this, the two fishman aliens showed surprise on their faces.

These ice crystal grass can only be used when refining several poisons, and this thing is not uncommon. Anyone can pick a lot of it by just going to the bottomless swamp, but someone actually wants to buy it in large quantities.

"Sorry, this thing is not widely used, so we only picked these." Another slightly older fishman alien shook his head.

"Okay, then give it to me." Yang Feng said lightly without asking any further.

He had already obtained the map of the green grassland from the lizard tribe and knew that these bitter flowers were produced in the bottomless swamp, so he could pick a batch at any time.

And the dozens of plants in front of him are enough for him to refine alchemy.

The two fishman aliens hurriedly wrapped these bitter flowers and handed them over.

Both parties handed over the money and delivered the goods in the other hand, and the transaction was completed quickly.

"My friend, you also want other spiritual herbs. Our fish clan is good at planting various spiritual herbs. You can see that the orchids are all over ten thousand years old. And these lycopene grasses are all just picked, and the medicinal properties have not been lost at all." The old fish man enthusiastically introduced other spiritual herbs.

Yang Feng has seen records of Ze orchids and Deer Pear grass in the lizard tribe's classics, which contain rich evil spirits and are considered quite precious spiritual herbs in the demon world.

But these things are useless to him, so he naturally won't buy them.

So Yang Feng shook his head at the other party, quickly left the stall, walked forward, but his eyes flashed with light.

This experience of buying Ku Luohua reminded him of this.

The Demon Realm and the Immortal Realm belong to two realms. If the materials are not available, it may be a priceless thing in the Demon Realm.

Now that he has come to the Demon Realm, he might as well collect more things like Ku Luohua, and return to the Immortal Realm in the future and make a big profit immediately.

Speaking of which, although he is not short of immortal stones, he naturally doesn’t think there are too many things. God knows when it will take a lot of needs, and when it needs it, it will seem a bit passive.

However, the names of these materials in the two worlds are different, so it is difficult to follow the map, so I can only search for them slowly by taking the opportunity.

He recalled the spiritual herbs or ores of the Yinsha attribute of the Immortal Realm, and at the same time he thought about it, emitting a little spiritual consciousness, and carefully investigated the surrounding stalls.

Now in the Demon Realm, Yang Feng seems extremely cautious about everything, for fear of being noticed by some intentional people, so he has never emitted divine thoughts before.
