"Your Excellency, but you've taken a fancy to something here?" one of them, a big man of the Yin Tiger Clan with a scar on his face, asked Han Li.

"I'm not here to buy something, can you buy things here?" Han Li asked rhetorically.

When the three big men heard this, they glanced at each other and were slightly surprised.

"If it's a good thing, we buy it. The Scarface man glanced Han Li up and down and said.

Han Li smiled faintly, turned over his hand and took out a palm-sized black jade box and handed it over.

The scar-faced man took the jade box, opened a gap, his complexion immediately changed, and he immediately closed the lid.

"Your Excellency, please come with me. Scarface made a respectful gesture to Han Li and ushered him into a dark room behind the stall.

After Han Li's observation, he found that there was basically such a dark room behind the stalls of each ethnic group, which was used for private transactions.

The furnishings in the room are extremely simple, only one table and two chairs, and runes are engraved on the walls, I don't know what the prohibition is.

The two sat down facing each other, and the Scarface man took a deep breath and opened the jade box again, only to see a fist-sized dark gray crystal lying in the box, covered with countless tiny holes, which looked like a beehive.

From time to time, a trace of gray mist emerges from all over the hive crystals, which looks a little mysterious.

"Your piece of Nightmare Hive Crystal is of very good quality, it can be regarded as the best, we will accept it, how many gray crystals do you want, or if you want to barter. Scarface said as he looked eagerly at the dark gray crystals in the box.

"Your Excellency is a real person, it seems that it is a wise choice to find your Yin Tiger Clan. In that case, let's get straight to the point, I want 300 gray crystals. Han Li smiled slightly and said.

"This ...... Three hundred is a bit expensive, and one hundred and sixty we will take it. Scarface looked embarrassed and gestured three fingers.

"Two hundred and seven!" Han Li said in a deep voice.

"One hundred and eighteen is the most!" Scarface shook his head.

The two of them bargained, and finally settled on two hundred gray crystals.

With a wave of his hand, Scarface took out a storage bone ring and handed it over.

Han Li took the storage bone ring, and his divine sense swept inside.

Inside was a small pile of gray crystals, each half the size of a fist, and a faint stream of gray gas could be seen inside.

This thing is called Gray Crystal, which is the currency circulating among the monks of the Gray Realm, and is a kind of thing similar to the Immortal Yuan Stone of the Immortal Realm, but what it contains inside is the extremely pure power of the Evil Yuan.

And the Nightmare Hive Crystal was a gray realm material that was obtained from the storage bag of the gray fairy's corpse back then.

It also took some money to get information, so Han Li sold this hive crystal first in exchange for some gray crystals.

He flipped over his hand and put away the bone ring of the storage, secretly happy in his heart.

This honeycomb crystal is just a very inconspicuous one of the many precious materials in the gray fairy storage bag, and it is not bad that it can sell two hundred gray crystals.

The other materials were even more worth, and the value of the storage bag seemed to be far beyond his expectations.

"This fellow Daoist, do you still have Nightmare Hive Crystals or other precious materials, instead of bothering to find other sellers, it is better to sell them all to me Yin Tiger Clan, you don't have to worry about the price, the Yin Tiger Clan has always had an excellent reputation, and it will never let you down. The Scarface Great Man put away the Nightmare Hive Crystal and looked at Han Li expectantly.

"I just stumbled upon it, and there's more to it out there. Han Li shook his head and said.

When the Scarface man heard this, a trace of disappointment flashed in his eyes.

"I don't have anything to sell to you, but I want to buy something from your Yin Tiger Clan. Han Li said with a slight smile.

"Oh, what do you want to buy?" said the Scarface man, with a smile on his face again.

"I'd like to buy some tomes from you Yin Tiger Clan. Han Li said.

"Classics, what classics?" the Scarface man was stunned for a moment, and then his eyes showed a look of vigilance.

"Your Excellency, don't worry, what I want is not the secret techniques of your Yin Tiger Clan, but those classics such as human geography and material illustrated books, preferably outside the June Grassland, or even outside the Black Tooth Domain. The Yin Tiger Clan is a big clan on the June Grassland, and there should be a lot of information and classics in this regard. Han Li said with a smile.

Just now when he walked all the way, there were only various materials on those stalls, and he didn't see a single classic book.

It is no wonder that the Talmuda Conference is mainly about trading all kinds of materials, and who will bother to collect any books.

Han Li wanted to collect all kinds of information, and the only way to do it was to use this method.

"It turns out that if you want these books, I can sell them to you, but these books are also collected by my clan, and the price is not cheap. The Scarface Man's face relaxed when he heard this, then he took a deep look at Han Li and said.

"As long as it is valuable textual information, the more the merrier. Han Li pointed his finger at the table and said with a smile.

"Well, you will wait a moment. Scarface stood up, turned and walked out.

Half an hour later, Han Li left the Yin Tiger Clan's stall, a faint smile on the corner of his mouth.

From the Yin Tiger Clan, he got a lot of classics.

He had just flipped through it, and many of them were outside the June Grassland, and some of them were materials outside the Black Tooth Domain, which were quite valuable.

Han Li didn't stop and continued to move forward.

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

The sky has darkened, and huge cages have been hung all over the trading area, and white fireflies are placed in them, emitting bright white light, illuminating the trading area.

As the night deepens, the trading area becomes more lively.

Han Li walked past the stalls one by one, and he was in a good mood.

For most of the day, he found two more ethnic groups, sold some materials, and bought some books about the gray world.

The three ethnic groups that Han Li had chosen were all big clans, and they had bought a lot of materials, far better than those books and materials of the gray lizard clan.

With a calculation in his mind, he decided not to continue buying books for the time being.

First, the materials he bought were almost enough, and the information of the various tribes in the grassland in June was closed, and the books and materials stored in the various tribes were almost the same, and many were duplicated.

Moreover, at the Talmuda Conference, it is quite a strange thing to buy classics everywhere, and if you do too much, I am afraid that it will attract the attention of those who are interested.

Han Li put his mind down and looked at the goods in the stalls on both sides.

Along the way here, he studied various classics of the gray lizard clan, and already had some ability to identify things in the gray world, plus his divine sense was incomparable, and he soon discovered a lot of good things.

"Hey, this is!" he stopped in front of a stall, his eyes under his cloak showing a hint of excitement.

The stalls here are not very large, most of them are spiritual grasses, ore materials and other things are not much, and there are two firstborn double horns standing behind the stalls, with fish scales on their faces, looking very much like the alien race of the fish people.

"What do you like about this friend?" a fish-man greets warmly.

Han Li looked at a box in the corner of the stall, which contained dozens of translucent plants, their leaves transparent and slender like ice crystals, and the veins inside were clearly distributed.

He was very familiar with this grass, and it was the bitter luohua, the main ingredient for refining the Susha Pill.

These materials, which were extremely precious in the fairy world, were stacked there quite casually at this moment.

"How do you sell these spirit grasses?" Han Li pointed to those bitter flowers.

"Oh, you want these ice crystal grasses? The fish-man said casually, and seemed to be enthusiastic for most of the time.

"Three Gray Crystal ......" Han Li was speechless for a while.

Kuluo flower is a top-level spirit grass in the fairy world, and it is very valuable, and many times even if there are immortal yuan stones, it cannot be bought, but it is so cheap in the gray world.

"Ice crystal grass, I seem to have heard of this name......" His heart moved, recalling the Gray Lizard Clan classics he had read a few days ago, and there was a book in it that seemed to mention this grass.

He thought about it for a moment, and some vague memories in his mind quickly became clear.

According to the book, the grass grows in shady and cold places, and there is a bottomless swamp deep in the June grassland, where a large number of ice crystal grass grows.

However, this ice crystal grass was of no use to the creatures of the gray realm, so it was only briefly described in that book, and no graphics were drawn, otherwise he would have recognized the ice crystal grass as the bitter flower.

The effect of the bitter flower is to dispel evil energy, which is harmful to the creatures of the gray world, no wonder it is so cheap.

"Is that all?" Han Li asked as he thought of this.

When the two fish-men heard this, their faces showed surprise.

These ice crystal grasses can only be used when refining a few poisons, and this thing is not rare, anyone who goes to the bottomless swamp can pick a lot, and some people want to buy it in large quantities.

"I'm sorry, but it's not very versatile, so we've only picked these. The other, slightly older fish-man alien shook his head.

"Okay, then give it all to me. Han Li didn't ask any more questions, and said lightly.

He had already obtained a map of the June Grasslands from the Grey Lizards, and knew that these bitter flowers were produced in the bottomless swamp, and he could go and pick a batch at any time.

And the dozens of plants in front of him were enough for him to use for alchemy.

The two fish-man aliens hurriedly wrapped up the bitter lobe flowers and handed them over.

Both parties paid the money with one hand and delivered the goods with the other, and the deal was quickly completed.

"This friend, do you want other spirit grasses, our Muyu clan is good at planting all kinds of spirit grasses, you can take a look at this Ze orchid flower, they are all more than 10,000 years old, and these withered grasses are all just picked, and there is no loss of medicinal properties. The old fishman enthusiastically introduced the other spirit grasses.

Han Li had seen the records of Zelan flowers and withered grass in the Gray Lizard Clan's classics, all of which contained a strong evil aura, and they were quite precious spiritual grasses in the Gray Realm.

However, these things are not of use to him, and he naturally will not buy them.

So Han Li shook his head at the other party, and quickly left the booth and walked towards the front, but his eyes flashed with a glint of light.

The experience of buying bitter locus flowers gave him a wake-up call.

The Gray Realm and the True Immortal Realm belong to two realms, and the materials are not passable, and what is worthless in the Gray Realm may be priceless when you get it to the True Immortal Realm.

Now that he has come to the Gray Realm, he might as well collect some more things like the Kuluo Flower, and when he returns to the True Immortal Realm in the future, he will be able to make a lot of money immediately.

Speaking of which, although there is no shortage of immortal yuan stones on his body now, this thing is naturally not too much, God knows when it will be needed, and it will be a little passive to think about it when it is needed.

It's just that the two worlds have different names for these materials, so it's hard to follow the map, so you can only try your luck and find it slowly.

He thought back to those yin and evil attribute spirit grasses or ores in the fairy world, and at the same time, his mind moved, and he exuded his divine sense a little, and carefully probed the surrounding stalls.
