Xiao Yin was stunned and said, "What's the matter?"

He Xinyin said: "Can you let the little sister come in and talk?"

Xiao Yin got up, pulled up the tent door, and invited He Xinyin in.

The two sat down cross-legged, and Xiao Yin said, "What the hell is going on? So mysterious?"

He Xinyin said with a hint of solemnity: "Now that it is a deep shift, most of us have rested. However, the younger sister wants to invite the senior brother to go to a place together. ”

"Where?"

"The underground black market. ”

Xiao Yin's face changed slightly: "Underground black market?"

He Xinyin nodded and said: "It is a secret underground exchange, which is mixed with dragons and snakes, but there is no shortage of all kinds of treasures, and it is a place worth visiting." ”

Xiao Yin said: "How did you know that there is such an underground black market here?"

He Xinyin said: "Before leaving, the master told me. When Shizun was young, he traveled widely and participated in this kind of underground black market trading many times. This Ancient Yin Ruins Trial has been held many times, and it has already held many underground exchange meetings in private. ”

Xiao Yin said: "Who organized this exchange meeting? Could it be the Southern Market City?"

He Xinyin said: "Listen to Shizun, it's not Nanxu City, but a secret chamber of commerce organization in the ghost domain, called the Tianxing Chamber of Commerce. This chamber of commerce is extremely powerful, and it has dealings with many forces, it can be said that it is all over the ghost domain, specializing in hosting all kinds of shady underground transactions, and its strength is extremely strong. ”

"Celestial Star Chamber of Commerce?"

Xiao Yin repeated it and immediately silently remembered the name.

He Xinyin said with a hint of expectation: "I heard from the master, this underground black market is mixed with dragons and snakes, and there are many insecurity, and forced buying and selling also happen from time to time. Can I accompany my little sister?"

Xiao Yin stared at He Xinyin and said, "You are in such a hurry to go there, do you know that there is something you want in it, can you tell me what it is?"

He Xinyin's face turned red and said, "Sure enough, I can't hide anything from Senior Brother." The little sister went here to find a piece of Ning Yuanjing. ”

"What is Ning Yuanjing?"

"A special kind of ore. It can help the monk condense the true qi of the Qi Mansion, and there is a certain chance to break through the bottleneck. ”

He Xinyin said, with a hint of amazement on her delicate face: "It has been more than five years since my little sister stepped into the True Qi Realm, and she has not yet seen a breakthrough opportunity. Master Venerable said that if you don't find a way to break through, you may be stuck in the True Qi Realm for the rest of your life. This Ning Yuanjing is a way out for me in this trial of the Ancient Yin Ruins, and I heard the master say that he had seen someone exchange this thing in the underground black market of the Ancient Yin Ruins. Therefore, the little sister moved her mind and hoped that the senior brother would be successful. ”

Xiao Yin pondered for a moment and said, "Okay, I'll accompany you on a trip." ”

He Xinyin was overjoyed and said, "Thank you, senior brother." ”

Xiao Yin waved his hand and said, "You're welcome. Where's this underground black market?"

He Xinyin said: "The master has already told me the route, and the senior brother will follow me." ”

After saying that, He Xinyin immediately got up, opened the tent door slightly and looked around, and found that there was no one else, so he turned around and nodded to Xiao Yin.

Xiao Yin carried the black box and was about to go out, but suddenly stopped and said, "Wait a minute, if you and I want to go to that kind of place, you can't go directly like this." ”

He Xinyin was stunned.

Xiao Yin said: "We need to change our faces." It seems that most people will not show their true colors in this shady underground black market transaction. It's better for you and me to change your clothes. ”

He Xinyin nodded hurriedly and said, "Senior brother is still thoughtful, but how to change his appearance?"

Xiao Yin didn't speak, just turned around, suddenly turned his body away from He Xinyin, and then urged the true yuan in his body to quickly swim between several meridians and bones.

There was a soft click.

Xiao Yin turned around again and faced He Xinyin again.

He Xinyin's pupils suddenly shrank: "Senior brother, you ...... What's your face?"

Xiao Yin, who appeared in He Xinyin's eyes, had turned into a strange young man with blank eyes, yellow face and thin muscles, and looked like a tuberculosis ghost.

Where can you still see Xiao Yin's original appearance.

This is exactly the thousand-faced-bone technique that Youhuan taught Xiao Yin in the north back then.

Xiao Yin said in his heart that there are a lot of people in this underground black market, maybe there are people from Junmo Academy and even the four major sects, if they show their appearance and are recognized, it will be very bad.

After all, he is a person who is on the wanted list of the sects in the Middle Earth Continent, and he really has to be more vigilant when he goes to this kind of place where there are many people.

Therefore, Xiao Yin remembered to use the Thousand Faces Yi Bone Technique to cover himself, of course, just in case, it was also necessary to change one or two for He Xinyin.

Xiao Yin looked at He Xinyin's surprised expression and said, "Don't panic, this is a disguise secret technique." It can be changed back at any time. ”

As he spoke, Xiao Yin turned around again, urging the Thousand Faces Yi Bone Technique mantra, and in one or two breaths, he returned to his original appearance.

He Xinyin let out a sigh of relief, and said with a little curiosity: "Can this technique be effective for others?"

Xiao Yin said: "Naturally. ”

As he spoke, Xiao Yin raised his hands and pressed He Xinyin's shoulders.

He Xinyin suddenly felt a cold current emanating from Xiao Yin's palm, along the meridians of his limbs, swimming all over his body, and when it passed by his cheeks, this cold current deliberately turned a few times along the cheek bones.

After Xiao Yin withdrew his palms, there was already an extra mirror in his hand: "Look at yourself." ”

He Xinyin looked at the mirror, and saw a girl dressed as a village girl with a fat and bloated body and an extremely exaggerated appearance standing inside, and he couldn't see He Xinyin's original appearance at all.

He Xinyin screamed, a little embarrassed: "It's so ugly!"

Then he habitually touched his hairband, but found that Xiao Yin's disguise secret technique had secretly taken off the hairband at some point.

He Xinyin glanced at Xiao Yin with some pity.

Xiao Yin was stunned for a moment, and explained with some embarrassment: "Some of them are too strong. Don't worry, I'll tune it down again. ”

As he spoke, Xiao Yin raised his hands again, held down He Xinyin, and urged again.

A moment later, a slender girl with a good face appeared in the mirror, compared to He Xinyin's original appearance, there was less heroism and more quietness.

He Xinyin looked at "himself" carefully for a long time, nodded with some satisfaction, and at the same time said embarrassedly: "There is Senior Brother Lao." ”

Xiao Yin saw that He Xinyin seemed to be very satisfied with this new look, and said, "Okay, then let's go." ”

As he spoke, Xiao Yin turned around and changed back to the appearance of the tuberculosis ghost just now.

He Xinyin looked at Xiao Yin's thin and ugly new appearance, opened his mouth, and wanted to persuade Xiao Yin to look better again, but after thinking about it, he was still embarrassed to say it after all.

Immediately, He Xinyin took Xiao Yin out of the account and walked down the remote path of the snow-capped mountain.

Along the way, Xiao Yin carefully looked at the various sect camps around the snow-capped mountain, and found that most of them were extremely quiet, and it seemed that the people inside had already fallen asleep.

Xiao Yin said in his heart, I don't know how many people here are actually the same as the two of them, who have secretly set off and rushed to the underground black market.

Even a sect like the Thousand Machines Sect, which can only be regarded as a second- or third-rate sect in Nanxu City, has disciples who know about the underground black market in the Ancient Yin Ruins, not to mention the rest of the first-line sects.

It's just that Xiao Yin is really interested in this kind of underground black market, and he also wants to know what it looks like there, and what treasures are being exchanged in it.

In addition, there must be many forces from all parties participating in the trial of the Ancient Yin Ruins in this underground black market, and it would be good if you could take this opportunity to see the reality of all parties.

The two walked along the snow-capped mountain road for dozens of miles, and after a while, they stopped at the mouth of a hidden small valley deep in the snow-capped mountains.

He Xinyin came to the rock wall of the valley mouth and began to tap with his fingers according to a certain pattern.

"Tuk Tuk ...... Sincere...... Sincere...... Tuk Tuk ...... Tuk Tuk Tuk ......"

The sound was crisp and clear, and it seemed that this huge rock wall was also extremely unusual.

He Xinyin knocked for a moment, and a rumbling sound came from behind the rock wall.

Immediately after, a man-wide crack suddenly opened in the huge rock wall, and out of it came a man with a black cloak whose face could not be seen clearly.

The man in black arched his hand towards Xiao Yin and He Xinyin, and then made a gesture of invitation to the depths of the crack and said, "There is a distinguished guest here, please inside." ”

Xiao Yin and the two glanced at each other, He Xinyin nodded, and the two followed the man in black into the crack in the rock wall.

As soon as the two entered, they heard another rumbling sound, and the crack in the rock wall behind them had closed, and they could no longer see the outside scene.

Xiao Yin's face remained unchanged, but He Xinyin showed a hint of vigilance.

The man in black seemed to notice He Xinyin's change, and said in a deep voice: "Don't panic the two distinguished guests, my Tianxing Chamber of Commerce has always guaranteed its reputation, and it will treat the distinguished guests who participate in the underground exchange meeting with courtesy." There are no ill intentions. ”

He Xinyin heard this and breathed a sigh of relief.

Xiao Yin's face remained the same, but he secretly let go of his perception and paid attention to everything around him at any time.

The two followed the man in black for a long time in the narrow crack, and suddenly felt cheerful in front of them, and a huge underground space with a size of dozens of acres appeared in the eyes of the two, which was furnished with countless stalls of all sizes, and there were people in various costumes shuttling back and forth on the stalls, and from time to time there were some quarrels, as if they were bargaining.

The man in black bowed and said, "This is the underground exchange place prepared by my Tianxing Chamber of Commerce for all the distinguished guests who have come from afar to participate in the trial of the Ancient Yin Ruins. ”
