“Has this esteemed guest taken a fancy to something here?” A burly Yin-Tiger clansman with a scar across his face asked Han Li, his voice buzzing.

“I’m not here to buy. Do you purchase items here?” Han Li countered.

The three burly men exchanged glances, a hint of surprise flickering in their eyes.

“If it's something of value, we naturally buy it,” the scarred man said, sizing up Han Li.

Han Li smiled faintly, flipped his hand, and produced a palm-sized black jade box, handing it over.

The scarred man took the jade box, opened a crack, and his expression immediately changed, quickly closing the lid.

“Esteemed guest, please come with me.” The scarred man made a gesture of invitation to Han Li, leading him into a dark room behind the stall.

After observing, Han Li noticed that practically every clan's stall had such a dark room for private transactions.

The room's furnishings were extremely simple, with only a table and two chairs. The walls were inscribed with runes, their purpose unknown.

The two sat facing each other. The scarred man took a deep breath and opened the jade box again. Inside lay a fist-sized, dark gray crystal, covered with countless tiny holes, resembling a honeycomb.

Wisps of gray mist occasionally emerged from the honeycomb crystal, giving it a mysterious air.

“This Nightmare Beehive Crystal is of excellent quality, a top grade piece. We’ll take it. How many Gray Crystals do you want, or perhaps you’d like to trade?” The scarred man said, his eyes fixed on the dark gray crystal in the box.

“You are indeed straightforward. It seems wise to have sought out the Yin-Tiger clan. In that case, let's get straight to the point. I want three hundred Gray Crystals,” Han Li said with a slight smile.

“That… three hundred is a bit steep. We’ll take it for one hundred and sixty,” the scarred man said with a troubled look, holding up three fingers.

“Two hundred and seventy!” Han Li said in a low voice.

“One hundred and eighty at most!” The scarred man shook his head.

After some haggling, they settled on two hundred Gray Crystals.

With a wave of his hand, the scarred man produced a storage bone ring and handed it over.

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

Inside was a small pile of gray crystals, each about half the size of a fist, with faint traces of gray gas flowing within.

This item, called Gray Crystal, was the currency used among cultivators in the Gray World, similar to Immortal Essence Stones in the Immortal World, but containing extremely pure Nether Essence power.

The Nightmare Beehive Crystal was a Gray World material obtained from the storage pouch of that Gray Immortal's corpse.

Since gathering information also required some expenditure, Han Li decided to sell the beehive crystal first to acquire some Gray Crystals.

He flipped his hand and stored the bone ring, secretly delighted.

This beehive crystal was just an insignificant item among the many precious materials in the Gray Immortal's storage pouch, yet it could fetch two hundred Gray Crystals, which was not bad at all.

The other materials were of unknown value, but the value of that storage pouch seemed to be far beyond his expectations.

“Esteemed friend, do you have any more Nightmare Beehive Crystals? Or other rare materials? Instead of going to the trouble of finding other buyers, why not sell them all to my Yin-Tiger clan? You don’t have to worry about the price. The Yin-Tiger clan has always had an excellent reputation and will never disappoint you,” the scarred man said, putting away the Nightmare Beehive Crystal and looking at Han Li expectantly.

“I only discovered this item by chance. There aren't any more,” Han Li said, shaking his head.

A trace of disappointment flashed in the scarred man's eyes upon hearing this.

“Although I don’t have anything to sell to you, I would like to buy some things from the Yin-Tiger clan,” Han Li said with a slight smile.

“Oh? What would esteemed guest like to buy?” The scarred man said, his face lighting up again.

“I would like to buy some books from the Yin-Tiger clan,” Han Li said.

“Books? What kind of books?” The scarred man paused, then a look of caution appeared in his eyes.

“Don't worry, I’m not interested in the Yin-Tiger clan's cultivation techniques or secret arts. I want books on human geography, material diagrams, and the like, preferably those pertaining to areas outside the June Grasslands, or even beyond the Black Tooth Domain. The Yin-Tiger clan is a major clan in the June Grasslands, so you should have a lot of information and books in this regard,” Han Li said with a smile.

As he had walked along, he had only seen various materials at the stalls, without a single book.

This was not surprising. The Tamuda Assembly mainly traded various goods, and who would bother collecting books?

Han Li wanted to collect various materials, and this was the only way.

“So you want these books. It is possible to sell them to you, but these books were collected with great effort by our clan, so the price won’t be cheap,” the scarred man said, his expression relaxing, and then he gave Han Li a deep look.

“As long as they are valuable books and information, the more the better,” Han Li said, tapping his finger on the table and smiling.

“Very well, please wait here for a moment.” The scarred man stood up and turned to leave.

Half an hour later, Han Li left the Yin-Tiger clan’s stall with a faint smile on his lips.

He had obtained a lot of books from the Yin-Tiger clan.

He had skimmed through them and found that many were about areas outside the June Grasslands, and some even contained information about the Black Tooth Domain, which was of great value.

Han Li didn’t stop and continued forward.

In the blink of an eye, more than half a day had passed.

The sky had darkened, and large cages were hung throughout the trading area, each containing white fireflies that emitted bright white light, illuminating the trading area.

As night deepened, the trading area became even more lively.

Han Li walked along the stalls, his mood quite good.

In the past half day, he had found two more clans, sold some materials, and bought some books about the Gray World.

The three clans Han Li had chosen were all major clans, so the information he bought was plentiful, far surpassing the books and materials of the Gray Lizard clan.

He pondered in his heart and decided to stop buying books for the time being.

Firstly, the information he had bought was almost enough. Moreover, the information of the various clans in the June Grasslands was closed, and the books and materials stored in each clan were similar, with many duplicates.

Moreover, buying books everywhere at the Tamuda Assembly was a rather strange thing. Doing it too much might attract the attention of those with ulterior motives.

Han Li put his thoughts aside and looked at the goods on the stalls.

On the way here, he had studied the Gray Lizard clan's various books and had acquired some ability to identify things in the Gray World. In addition, his divine sense was powerful beyond compare, and he soon discovered many good things.

“Eh, this is!” He suddenly stopped in front of a stall, a trace of excitement appearing in his eyes beneath his cloak.

The stall was not large, and most of the items were spiritual herbs, with few ores and materials. Behind the stall stood two alien races with horns on their heads and fish scales on their faces, who looked very much like mermen.

“Esteemed friend, have you taken a fancy to something?” One of the mermen alien races greeted him warmly.

Han Li’s gaze fell on a box in the corner of the stall, which contained dozens of translucent plants with clear and distinct veins distributed within leaves transparent and thin like ice crystals.

He was very familiar with this grass, which was the main material for refining the Subduing Nether Pill, Bitter Luo Flower.

These materials, which were extremely precious in the Immortal World, were now piled there casually.

“How are these spiritual herbs sold?” Han Li asked, pointing to those Bitter Luo Flowers.

“Oh, you want these Ice Crystal Grass? Three Gray Crystals each,” the merman alien race said casually, seemingly having lost most of his enthusiasm.

“Three Gray Crystals…” Han Li was speechless.

Bitter Luo Flower was a top-grade spiritual herb in the Immortal World, very valuable, and often could not be bought even with Immortal Essence Stones, yet it was so cheap in the Gray World.

“Ice Crystal Grass, it seems I’ve heard of this name…” He thought to himself, recalling the Gray Lizard clan’s books he had read a few days ago, one of which seemed to mention this grass.

After a brief recollection, his vague memory quickly became clear.

According to the records in that book, this grass grew in yin and cold places, and there was a bottomless swamp deep in the June Grasslands where a large number of Ice Crystal Grass grew.

However, this Ice Crystal Grass was useless to Gray World creatures, so the book only briefly mentioned it and did not draw a picture. Otherwise, he would have recognized that the Ice Crystal Grass was indeed the Bitter Luo Flower.

The effect of Bitter Luo Flower was to dispel Nether Qi, which was harmful to Gray World creatures, so it was no wonder it was so cheap.

“Is this all you have?” Han Li thought to himself, and then asked.

The two mermen alien races both looked surprised when they heard this.

These Ice Crystal Grass could only be used when refining certain poisons, and they were not rare. Anyone could pick a lot of them as long as they went to the bottomless swamp. Someone actually wanted to buy a large quantity.

“I’m sorry, this thing is not widely used, and we only picked these,” another slightly older merman alien race said, shaking his head.

“Okay, then give them all to me,” Han Li said indifferently without asking further.

He had already obtained a map of the June Grasslands from the Gray Lizard clan and knew that these Bitter Luo Flowers came from the bottomless swamp. He could pick a batch at any time.

Moreover, the dozens of plants in front of him were enough for him to refine pills.

The two mermen alien races hurriedly packed up the Bitter Luo Flowers and handed them over.

The two sides exchanged money and goods, and the transaction was completed quickly.

“Esteemed friend, do you want any other spiritual herbs? Our Mu-Fish clan is good at growing all kinds of spiritual herbs. You can take a look at these Ze Lan Flowers, all of which are over ten thousand years old, and these Ku Ling Grass, which have just been picked and have not lost any of their medicinal properties,” the older merman introduced the other spiritual herbs enthusiastically.

Han Li had seen the records of Ze Lan Flower and Ku Ling Grass in the Gray Lizard clan's books, which contained rich Nether Qi and were considered relatively precious spiritual herbs in the Gray World.

However, these things were of no use to him, so he would naturally not buy them.

So Han Li shook his head at the other party and quickly left the stall, walking forward, but his eyes were flashing with light.

The experience of buying Bitter Luo Flower had given him a reminder.

The Gray World and the True Immortal World belonged to two different worlds, and the materials were not connected. Things that were worth nothing in the Gray World might be invaluable in the True Immortal World.

Now that he had come to the Gray World, he might as well collect more things like Bitter Luo Flower. When he returned to the True Immortal World in the future, he could make a fortune immediately.

Speaking of which, although he didn't lack Immortal Essence Stones now, he would never嫌多, and who knew when he would need them in large quantities? It would be a little passive to consider it when he needed them.

It was just that the two worlds had different names for these materials, so it was not easy to follow the clues, and he could only rely on luck to find them slowly.

He recalled the yin and evil attribute spiritual herbs or ores of the Immortal World. At the same time, he moved his mind and slightly spread out his divine sense to carefully explore the surrounding stalls.
