After transmigrating into the body of the Jade Rat Spirit, I became Nezha's adopted sister.

"Yi Bao Hui?" Bai Yeying blinked; the name sounded intriguing.

"Yes!" Huang Wu explained, gesturing wildly.

"It's just that we mountain spirits and rogue demons occasionally gather together, each taking what we need! Some exchange spiritual herbs for pills, some exchange ores for magical artifacts, and some exchange information for protection... In short, anyone with a reputation in the Three Mountains and Five Peaks, or who has some rare items, might go! Madam, what do you think, should we go and take a look? Maybe we can find something useful for cultivation!"

Bai Yeying was intrigued. Although the spiritual energy of Trap Mountain was decent, its resources were limited, and progress was slow as she relied entirely on her own exploration and the collection efforts of the lesser demons.

If there's a chance to exchange for some cultivation methods, or auxiliary pills, or even just to take a look and broaden one's horizons, that would be good too.

"Is it safe?" she asked, voicing her biggest concern. Places where fairies congregate often signify chaos and danger.

Huang Wu scratched his head: "The old ape spirit said that Liuyun Ravine is a special place. It's maintained by several old demons who have some cultivation and are particular about rules. Fighting is prohibited during the Treasure Exchange Gathering. Violators will be expelled or even killed by a joint effort. So generally speaking, it's quite peaceful. As long as you follow the rules, don't flaunt too much wealth, and don't cause trouble, there shouldn't be any major problems."

Cuiluo, who was listening nearby, said with some concern, "Madam, we are unfamiliar with that place..."

"It's precisely because we're unfamiliar with it that we need to go and take a look," Bai Yeying decided. "If we always stay cooped up in Trap Mountain, our horizons will be narrowed. Huang Wu, find out the exact time and place again, and the rules we need to be aware of. Cui Luo, help me prepare some local specialties that we might not need, but that others might be interested in."

The local specialties she mentioned were nothing more than some old herbs from the mountains, some minerals containing a faint spiritual energy, and a few pieces of good quality bones and claws that had been processed and taken from the Black Wind Monster last time.

Oh, and there are also a few bottles of Qingxin Powder that she made herself, which have a negligible effect. The main ingredients are mint and Ningshen Grass with a little bit of demonic energy as a catalyst.

Three days later, everything was ready.

Bai Yeying temporarily entrusted the affairs of the cave to Cuiluo and Tenghan, while she transformed into a pretty but unremarkable girl in a yellow dress, carrying a cloth bag containing items to be exchanged and some dry food and money.

Huang Wu insisted on following her, claiming he would be her guide and bodyguard. Bai Yeying couldn't persuade him otherwise, so she took him along, turning him into a lean and clever young servant.

The master and servant (demons) left Trapped Sky Mountain and headed south.

Seven or eight hundred miles is not a long distance for Bai Yeying now. She deliberately controlled her speed, observing the mountains, rivers, and spiritual energy along the way as she traveled, which was also a form of cultivation and gaining experience.

The closer one gets to Liuyunjian, the more mixed and obvious the demonic aura in the air becomes.

Occasionally, other figures could be seen hurrying along in the mountains and forests. Some had transformed into human form, while others retained some of their original features. Most of them were in a hurry and maintained a wary distance from each other.

Liuyun Ravine is nestled between two precipitous mountain peaks. A waterfall cascades down like a white ribbon, carving out a deep pool at the bottom of the ravine. The air is filled with mist, and the spiritual energy is indeed much richer than the surrounding area.

On the rock walls on both sides of the ravine, many caves and platforms of varying sizes have been naturally formed, and many figures have already gathered there.

It seems that YiBao Club has already started.

There are no fixed stalls; people stand or sit, displaying the items they want to exchange in front of them, or simply shouting out their needs.

The sounds were chaotic, and various smells mingled together: the freshness of grass and trees, the earthy smell of minerals, and the pungent odor of animals—a bizarre and surreal scene.

Bai Yeying, accompanied by Huang Wu, concealed their auras and blended into the demon horde, slowly strolling around. She decided to observe more and speak less, assessing the local situation.

"A century-old fire cloud grass, traded for a handy steel fork!"

"I need three ounces of refined black iron and one water-elemental amulet!"

"A pair of Gale Wolf King fangs, highest bidder wins, spirit stones or pills are acceptable!"

"Selling a detailed map of the Blackwater Marsh, guaranteed authentic!"

The sounds of hawking and bargaining filled the air. The items being exchanged were varied and mostly of little use to Bai Yeying, or simply unaffordable for her; for example, spirit stones, which she had never even seen before.

She saw a few herbs with decent spiritual energy, but she didn't have what the other party wanted in exchange; she also saw a book, "Basic Qi Induction Techniques," but the stall owner was a shifty-eyed fellow who was asking for an outrageously high price and had a vacant look in his eyes, making him seem unreliable at first glance.

After wandering around for most of the time, I found very little.

Bai Yeying was feeling somewhat disappointed and was planning to exchange what she had brought for some useful medicinal herbs or refined iron when her gaze was suddenly drawn to a small stall in the corner.

The stall owner was an elderly man dressed in gray linen clothes, with some gray hair. He sat cross-legged with his eyes closed, and in front of him was a small, broken jade slip about the size of a palm. Next to him stood a small wooden sign with the words written in charcoal: "Fragment of an ancient cultivation cave, exchangeable for a mind-clearing elixir or an equivalent spiritual item."

An ancient cultivator's cave? Bai Yeying's heart skipped a beat. Although it was most likely a bluff, the old man's aura was calm and collected, unlike a cunning person, and his requirement for calming items was quite unusual.

She stepped forward, squatted down, and examined the jade slip carefully.

The jade is rough, with broken edges and some blurry lines carved on it, indicating that it is quite old, but it is impossible to see what it depicts.

"Father-in-law, this map..." Bai Yeying began.

The old man slowly opened his eyes, his gaze cloudy yet clear. He glanced at Bai Yeying, then at Huang Wu behind her, and said in a hoarse voice, "The map is incomplete, and its location is roughly in some deep mountain in the northwest. I obtained it by chance years ago, studied it for many years, but gained nothing. I almost ruined my state of mind due to the residual chaotic thoughts within it. Now I only want to exchange it for some calming and tranquilizing medicine to nourish my soul. If you have any, young lady, you can take a look."

Bai Yeying thought for a moment, then took out a small jade bottle from her cloth bag. It was the Qingxin Powder she had made herself.

"This is a calming powder I concocted, with Concentrating Grass as the main ingredient, supplemented with several calming herbs. It has a slight effect on stabilizing the mind and dispelling distracting thoughts. Would you like to examine it, sir?"

The old man took the jade bottle, uncorked it, and brought it close to his nose, a glint of light flashing in his cloudy eyes. He then poured a little powder into his palm, examined it carefully for a moment, and nodded.

"Although the medicinal power is weak, the refining technique is acceptable, and the medicinal properties are moderate and mild, which is exactly what this old man needs. I will exchange this incomplete map with you, young lady."

The transaction went smoothly. The old man put away the Tranquilizing Powder, pushed the jade slip in front of Bai Yeying, then closed his eyes again and said nothing more.

Bai Yeying picked up the jade slip; it felt slightly cool to the touch. She tried to probe it with her demonic power, but the jade slip didn't react at all, just like an ordinary broken stone.

But she could vaguely sense that something inside the jade slip was blocking her from probing, and the chaotic residual thoughts the old man had mentioned might not be unfounded.

"Madam, is this thing reliable?" Huang Wu leaned closer and whispered, "It looks like a piece of broken jade."

"Who knows? Just consider it a change of medicine." Bai Yeying carefully put away the jade slip. The ingredients for the Qingxin Powder she refined were all gathered from the mountains, with almost zero cost. Exchanging it for such a small item that might have a story behind it was not a loss.

After browsing the treasure fair for a while, exchanging some ores and herbs for some high-quality refined iron and several packets of spices that could only be bought in human towns, Bai Yeying decided to leave. This place was a melting pot of all sorts of people, and staying there for too long wasn't comfortable.

Just as she was about to lead Huang Wu out of Liuyun Ravine, a commotion suddenly broke out from the side.

"Stop! You stole my Earth Spirit Fruit and you think you can get away?!" a rough voice roared.
