In the early morning, the morning sun spills through the window lattice and spills into the room, cutting into dots and mottles.

When a ray of sunlight shone on a little black soil foam on the ground, Ye Nan in the space in his body suddenly opened his eyes.

"The damage to my soul yesterday has healed, and the distance has increased by four or five zhang, and now my soul power can spread to about thirty-four or five zhang around my body. ”

Ye Nan groaned slightly, and his gaze turned to the yin spirit in the corner of the space.

This yin spirit was curled up at the moment, but its face was hideously distorted, and sometimes a trace of evil aura continued to emanate.

"I'm getting weaker and weaker in my control over this yin spirit now, and now it's time to buy a set of demon-raising techniques!"

Ye Nan knew that if it was another day or two, his control over the Yin Soul would completely disappear. When the time comes, it will be even more difficult to control this yin spirit.

After thinking about it, Ye Nan's figure flashed and walked out of the internal space.

After locking all the doors of the courtyard, Ye Nan first went to the Hidden Scripture Pavilion and the Elixir Pavilion, and took out a set of low-level martial arts and cultivation resources that he should obtain after advancing to the inner disciples, and then headed towards Tianniu City.

Tianniu City was still very lively, with inner disciples in black robes coming and going, and in addition, Ye Nan also saw many loose cultivators with strong breaths.

"It turns out that the scattered cultivators of the realm above the eightfold realm of refining the body can also enter this place!"

Ye Nan's appearance changed at this moment, transforming into an ordinary-looking inner disciple. At the moment, I was a little surprised to see a lot of loose cultivators dressed in various costumes around me.

He had been to Tianniu City once before, and he was not familiar with the rules here. Now I know that Tianniu City is also open to casual cultivation, but there are restrictions on cultivation.

Ye Nan walked slowly in the Heavenly Cow City, he did not go to the Feng family's station, but went straight to the Devil's Exchange.

When he just walked in front of the inky black building of the exchange, a cold aura came to his face, making people feel cold.

"The sinister aura here is very strong, and there should be a lot of demons in it!"

Ye Nan's eyes flickered for a moment, and then he stepped into it.

As soon as I entered the Devil's Exchange, my eyes suddenly darkened, as if I had fallen into the dark night in an instant, which made it difficult for the eyes to adapt.

Ye Nan saw that there was not much light here, and it was extremely dim, but with his eightfold strength of refining his body, after running the spiritual power into his eyes, his eyes became clear.

This is a hall of nearly 1,000 square meters, and the hall is full of counters, and all kinds of monsters are placed in it.

"Sealing the Demon Disk, Subduing the Demon Stick, Demon Suppression Lock......"

Ye Nan looked at the many unheard of monsters at this moment, and his eyes were extremely dazzled.

Ye Nan kept walking in front of the many counters slowly, but he found that there were not too many martial artists here, and even the many stall owners in front of the counters were bored one by one.

After a while, Ye Nan came to a counter that sold demon-raising techniques.

Looking up, I saw that there were only a few sets of low-level demon cultivation techniques on the counter, which were extremely rare, and there was no set of intermediate and high-level techniques among them.

"Is there a higher-level demon cultivation technique for sale?" Ye Nan frowned slightly, and immediately glanced at the stall owner who was resting on the counter.

"Demon cultivation techniques are extremely rare, and the more advanced ones can only be bought at auctions, and there are no them here!"

The stall owner raised his head, glanced at Ye Nan, and said lazily: "If you use it to learn demon cultivation and demon control, these low-level techniques are enough!"

Hearing this, Ye Nan glanced at the rest of the counters and found that it was indeed as the stall owner said, there were no advanced demon cultivation techniques here. Only then did he nod and picked out a set of Demon Duel from the counter and bought it.

Later, Ye Nan spent another two thousand gold coins to buy a Demon Sealing Disk and two Yin Demon Beads from the rest of the counters.

And just as Ye Nan was about to leave, he found some warriors walking down a dark corridor towards the bottom of the hall.

Immediately, Ye Nan inquired with some stall owners and learned that this was only the first floor of the Devil's Exchange, and there were second or even third floors below it.

"No wonder there are so few martial artists here, it turns out that there is another mystery underground!" Ye Nan smiled lightly, and then stepped towards the dark corridor.

As soon as he entered the corridor, Ye Nan saw that there was a checkpoint here, and each warrior was released after paying twenty gold coins.

After Ye Nan paid the twenty gold coins, he was immediately greeted by a steward in his thirties.

This steward's cultivation is enough to refine the body ninefold, his eyes are dripping, very slippery, and at this moment, he looked at Ye Nan with a smile on his face and said, "Little brother should be here for the first time, right?"

Hearing this, Ye Nan was slightly surprised, and secretly sighed in his heart that this steward's eyes were vicious. He nodded and did not deny it.

"I'm the king's steward, let me introduce our little brother to our devil exchange!"

While walking with Ye Nan, Steward Wang said slowly: "Our exchange is divided into three floors, the upper floor is the Demon Selling Hall, the second floor is the Demon Fighting Field, and the third floor is the Demon Raising Cave!"

"Oh?" Ye Nan was surprised in his heart, but he didn't expect that it would be divided into three parts.

Seeing Ye Nan's expression, a hint of pride flashed across Steward Wang's face: "The little brother in the demon sales hall on the first floor has already seen it, and they are all selling some things used to raise demons.

And the second layer of the Demon Fighting Arena is a place for demons to compete in skills. Here, the warrior can release the demon he raises to fight, and the winner can not only get the magic crystal of the opponent's demon, but also have a stake reward. Of course, if you don't participate in the competition, you can also place bets here!"

"And the last layer of the Demon Cultivation Cave is an excellent place for martial artists to raise demons, where there is enough yin and evil energy, which can make their demons grow rapidly, and of course the cost is also the highest!"

After listening to Steward Wang's narration, Ye Nan had a new understanding of the devil's exchange in his heart.

"Okay! There are other customers to entertain here, so don't bother the little brother! I wish the little brother a good time here!"

With that, Steward Wang smiled at Ye Nan, slowly turned around and walked towards the entrance corridor again.

Ye Nanzhi said that this person should be the person in charge of introducing the martial artist here, and he didn't care about it at the moment, and slowly stepped into the second floor of the basement.

As soon as I entered the second basement floor, there was a noisy sound in my ears. Looking up, the crowd here is boiling and lively.

"Eat! Eat that guy's crystal!"

"Stupid, suck it up! suck it up and drain me!"

"Hide! ** If you don't hide again, Lao Tzu's money will be lost!"

“......”

I saw that the second floor of the underground is 2,000 zhang long and wide, and there are rings in it, and the demonic energy on the stage is surging, and the demons are fighting hard, and the crowd around the ring is constantly shouting, and the noise is abnormal.

Ye Nan saw that there was a huge crystal notice on one side of the hall, which flashed to show the odds of each of these ring fighting demons, and below this crystal notice were betting stalls.

In addition, there are many scantily clad and glamorous girls who constantly shuttle through the crowd, providing these gamblers with fine wine and refreshments.

"It's a great place to have fun!"

Ye Nan smiled lightly, seeing that there were not only scattered cultivators and inner disciples, but also many people from the four major families.

Turning his gaze to the rings. I saw that the demons on it were hideous and ferocious, frantically absorbing the opponent's demonic qi and gnawing the enemy's magic crystals.

After taking a look at the place, Ye Nan shook his head and walked towards the third floor.

He now has demon-raising techniques and demon-raising aids, but he is desperate to make his Yin Soul promote to become a demon.

There is also a card at the entrance of the third floor, and at this moment, Ye Nan paid a hundred gold coins, received a token, and stepped into the third layer.

There were hundreds of caves in the third layer, and as soon as Ye Nan entered at this moment, he felt that the yin and evil qi here had almost condensed into substance.

"What a terrible aura!"

Ye Nan felt a trace of evil qi and wanted to drill into his skin, and he was a little shocked in his heart.

"Demon Cave No. 180!" Ye Nan glanced at the number of the token in his hand, and then distinguished the lower position, and walked quickly in one direction.

Before walking to his own demon cave, Ye Nan put the token in his hand on the stone wall of the cave door, and the inky black cave door opened.
