The Black Iron Castle's trading conference can be said to be mixed, and the people who come here to participate in the trading conference are scattered cultivators from all over the continent.

Therefore, there are righteous monks and demonic monks who come here, not only casual cultivators, but even some monks from regular sects who come here to participate in the conference, which can be said to be very noisy.

"This monk, the pill that has just been baked, do you want to buy some, it is suitable for the Jindan stage and the Yuan infant stage."

"The elixir is on sale, all of them are picked by yourself, don't miss it when you pass by."

"All kinds of new flying swords have been sold."

“……”

At the top of the hill of the Black Iron Castle is a huge platform on which all the monks put their things for sale, and it is lively like a bazaar.

However, at a glance, it is clear that behind this seemingly scattered chaos is actually orderly, because every once in a while, a monk in the same costume will closely watch the movements around him, and they are the guards of the Black Iron Castle.

The strength of these guards is not low, and it is also above the Yuan Infant Stage to take out any of them, it seems that this Black Iron Castle is an existence that is not easy to underestimate on the Immortal Yuan Continent.

Han Ning's purpose was to buy essence blood, and he went directly to the demon cultivator's stall, which was only for these people to collect essence blood.

After turning around the stall for a while, Han Ning finally saw a demon cultivator shrouded in a black robe, Han Ning walked over, and in this demon cultivator's stall, there were indeed some bottles marked with essence blood, Han Ning asked, "What level of cultivator are these essence bloods?" ”

The demon cultivator raised his eyes and looked at Han Ning, a little surprised, "This fellow Daoist is not a demon cultivator, why do you need essence blood, is it possible that the current righteous path cultivators also need essence blood."

Han Ning didn't bother to talk nonsense with him, "Of course, this essence blood has its own effect." You just say whether to sell or not. ”

The Demon Dao Cultivator is open to do business, but he has more words, of course he still wants to earn it with spirit crystals, "These essence blood are all condensed by the Demon Dao Cultivator in the Jindan Period, and they are absolutely pure." ”

"It's too low." Han Ning shook his head, and then he turned to leave.

At this time, the Demon Dao Monk got up and said, "Wait. What level of demonic essence blood do you want? ”

"Can you get it?" Han Ning asked rhetorically.

"If you say it's possible."

Han Ning said: "At the very least, it is also the essence blood of a monk in the Yuan Infant Stage. ”

The Demon Dao Monk was a little stunned, this Han Ning was really a lion's mouth, it was a very difficult thing for this monk to condense essence blood, and it was also a difficult thing to kill a Yuan Infant Monk, "This high-grade essence blood is very expensive, can you afford it?" ”

"If you can get it, I can afford it." Han Ning deliberately showed a look of disdain.

The Demon Dao Monk hesitated and said, "Wait a minute, I have a bottle of Distraction Stage Monk's essence blood here." 50,000 top-grade spirit crystals. ”

This good thing is really hidden at the end, Han Ning said: "Fifty thousand top-grade spirit crystals are given to you, and the things are given to me." With that, he took out the crystal card that Bu Qingyun gave him, which was similar to a modern bank card.

As soon as Han Ning took out this card, the eyes of this demon monk suddenly lit up, a poor monk would not be able to take out such a card. It can be seen that Han Ning is a wealthy monk, and he took out a porcelain vase from the treasure in his arms. "Here are ten drops of the essence blood of a distraction monk."

Han Ning took the porcelain bottle, and at the same time took the crystal card and touched it with the card of the Demon Dao Monk, and the Demon Dao Monk's card suddenly had 50,000 top-grade spirit crystals on it.

"Does this fellow Daoist need anything else?" The essence blood of this distraction period cultivator is certainly valuable, but these 50,000 top-grade spirit crystals are not a small amount, and he has made a lot of money, so he is naturally happy.

"All I need is blood." Han Ning said lightly. These essences and blood were still not enough for him.

The Demon Dao Monk said to Han Ning: "For the sake of Daoist friends being so bold, I will bring you to a stall, this is a senior I know, he must have high-end goods in his hands, but this person's temper is a little strange." Daoist friends will have to bear more at that time. ”

"Okay, please lead the way." Han Ning said, he suddenly became interested.

After earning a sum of spirit crystals from Han Ning, the Demon Dao Monk felt that there was no need to set up his stall, so he took Han Ning to spare half a circle on the huge platform, and found the strange person in his mouth in a corner.

This person was also wearing a black robe, and there were pills, spirit weapons, elixirs, and spirit beast eggs on his stall, and many monks gathered in front of him, and from time to time they took out one thing to show this person, and this strange man just shook his head or nodded.

"This is the predecessor of our Demon Dao, he has a quirk in business, he doesn't want spirit crystals, just barter, as long as it is something he sees, he will exchange a lot of things."

Han Ning nodded and walked to the front of the stall, there were still many monks waiting here at this time, they looked at the things on this strange man's stall eagerly, I have to say that the things sold by this strange man were all superb, and it was no wonder that some righteous monks didn't care that it was a monk who set up the stall.

"Do you have a high-level essence blood?" Han Ning asked directly.

The strange man Demon Xiu glanced at Han Ning and pointed to the sign in front of the stall, which said Barter.

Han Ning glanced at this Demon Dao Cultivator, his cultivation was in the late stage of integration, and he was about to cross the Tribulation, and according to what he knew from that Demon Dao Monk, this strange Demon Cultivator was a loose cultivator, so what he must be afraid of was the Tribulation.

Because even the monks of the orthodox famous sect are cautious and do everything possible to get a Tribulation Pill, and for Demon Cultivators, the special Tribulation Pill is called the Demon Tribulation Pill, which is still a little different from the righteous Path's Tribulation Pill.

And this elixir is even rarer.

Han Ning had been asking Ning Yu to collect storage rings and items from various Heavenly Cultivators in the Heavenly Court, this Demon Tribulation Pill was quite a lot, and as soon as his hand moved, a vermilion box appeared in his hand.

The strange demon cultivator focused on Han Ning at this time, just as Han Ning thought, he had been looking forward to the Demon Tribulation Pill.

With a smile on the corner of his mouth, Han Ning gently pushed away the sunspot, and suddenly an elixir the size of a quail egg appeared in the box like a dark night.

"Demon Tribulation Pill." Without waiting for Han Ning to speak, someone had already shouted out, and these people were naturally Demon Dao cultivators.

The strange man Demon Xiu's body trembled, and there was a slight tremor in his tone, "What do you want to change?" ”

Han Ning closed the lid of the box, and there was immediately a sigh around him, and he said, "I want high-grade essence blood, all of them." ”

"As you wish." The strange man Demon Xiu took out ten porcelain bottles from the storage ring, "Three Yuan Infant Period, four Out-of-Body Period, and three Merge Period, is it enough?" ”

Han Ning was overjoyed, "That's enough." ”

He put all the porcelain vases into the ring, and threw the Demon Tribulation Pill in his hand to the strange man Demon Xiu, this trip to the Black Iron Castle was worthwhile.

"This fellow Daoist, please stay." Han Ning was about to leave when a voice sounded behind him. (To be continued.) )
