"Buzz!" The special talisman in Jiang Yun's storage bag vibrated regularly several times and then stopped.

This is the signal Jiang Yun usually receives notifications from underground trade fairs. Usually, Jiang Yun will then head to the entrance of the underground trade fair. This is exactly what happened when he obtained the Sky Iron in the last trade.

This time, Jiang Yun hesitated. Word of the alchemy had already spread. Even his neighbors had heard about it, and Jiang Yun found it hard to believe the Demon Suppression Division wouldn't get the news. Furthermore, the other party was targeting the same cultivator who had been involved in the unidentified sale of Foundation Establishment Pills.

"Do you want to go?"

Jiang Yun hesitated, but the Purple Cloud Glazed Crystal was something Jiang Yun must obtain. Thinking of this, he turned around and left his residence, walking calmly towards the outer city.

Not long after, a man appeared in the outfit he usually wore when entering the underground trade fair, wearing a conical hat, a white robe, and an embroidered storage bag hanging around his waist.

"Creaky!" Jiang Yun pushed the door open and entered. Sure enough, the black-robed foundation-building cultivator who usually received him was still there.

"Daoyou is here. The raw materials are ready. Follow me and prepare to refine!" The black-robed monk said as he prepared to take Jiang Yun to the backyard. Jiang Yun had refined pills for him before, but this time Jiang Yun did not follow.

"Wait a moment, I want to take it back and refine it."

After hearing this, the black-robed monk turned around in disbelief and said:

"This is against the rules!"

"You were the ones who broke the rules first. Tell me how many people know about this."

Jiang Yun said coldly while standing in place, his right hand was placed on the storage bag so that he could take out the magic weapon at any time.

"This..." The black-robed monk hesitated. This time, in order to expand the reputation of the underground trade fair, he did release the news about the Foundation Establishment Pill.

"No, what if you don't come back after refining it?"

The black-robed monk thought about it and shook his head and said: The materials for the foundation-building pill are too rare, we can't take the risk.

"How about this, give me the reward now and I'll go for you."

Jiang Yun proposed a compromise.

"This.....Please wait a moment, let me ask."

After the black-robed monk finished speaking, he turned around, took out a sound transmission talisman, and reported the situation one by one. After a while, he turned to look at Jiang Yun and said:

"Okay, we promise to give you the things first, but you have to guarantee to produce at least three pills."

"I'll try."

Jiang Yun nodded and said, seeing this, the black-robed monk said nothing more, no one can guarantee the quality of the elixir that the alchemist can make.

After a while, a Qi Refining cultivator entered from the backyard and handed a storage bag to the black-robed cultivator.

"This is it, check it out."

Jiang Yun took the storage bag and scanned it with his spiritual sense. Suddenly, a glass crystal with a purple glow was lying quietly in the storage bag. It looked to be the size of an adult's fist, which was enough for Jiang Yun to use.

"Okay, let's go!"

Jiang Yun followed the other party to the backyard and then entered an inconspicuous room. The black-robed monk opened the floor under the bed, revealing a dark hole.

"Please!" The black-robed monk pointed at the cave entrance and said:

Jiang Yun was not afraid either. At least there would be no danger before he successfully refined the elixir.

At this time, around the shop, several monks looked at the courtyard carefully and whispered:

"Commander, do you want to take action? The enemy has already entered."

The commander of the Demon Suppression Division beside him shook his head and said:

"Wait a little longer, until the other party finishes refining the elixir. Let Shadow keep an eye on it at all times."

Jiang Yun entered the underground passage with ease and arrived in front of a busy alchemy room. At this time, there were already several cultivators waiting in the alchemy room.

These are the main members of the underground trade fair, and all of them are at the Foundation Establishment stage.

"Master Gu Dan, please."

Jiang Yun nodded after hearing this, took the storage bag handed over by the other party, and walked into the alchemy room.

Jiang Yun opened the storage bag, which was filled with jade boxes. He opened one of the jade boxes and saw three black second-level demon pills lying quietly inside, emitting a hint of demonic energy.

"Three water-attribute level 2 demon pills!"

The method of refining medicinal pills is still imperfect, and can only use demon pills with softer properties such as water, wood, and earth to replace the three main ingredients. Therefore, it is extremely rare to have three demon pills for one set of foundation-building main ingredients.

After finishing the inspection, Jiang Yun took out the second-level alchemy furnace he carried with him, input mana, and the earth fire immediately surged up, and he began to refine the pill.

Outside the alchemy room, three foundation-building cultivators from the underground trade fair stared intently at the door. One of them, with narrow cheeks and snake-like eyes, whispered:

"Just let him go like before?"

The monk among them was tall, wearing a black and white mask on his face, and said in a cold voice:

"Don't worry, wait until the other party finishes refining. Then I will talk to this fellow Taoist in person."

He turned around and looked at the monks around him. Through the black and white masks, a pair of cold and narrow eyes shot out a cold light, which made the other monks standing around shiver.

The black-robed monk who brought Jiang Yun down last said:

"The other party has no intention of breaking the contract. This kind of cooperation is the safest. If we rashly fall out, I'm afraid it will be difficult to meet a second-level alchemy master in the future."

"Humph! If we can get him into our hands, our power will expand more than tenfold. Then, Big Brother and we will have a chance to advance to the Golden Core stage."

The monk who had just had a long and narrow expression said coldly after hearing what the black-robed monk said:

The eldest of them waved his hand, and the two of them stopped talking.

At this time, Jiang Yun in the alchemy room had already finished refining the first batch of pills. Unfortunately, there was a small mistake in a step in the middle, and he only got an ordinary quality foundation-building pill, which was considered a defective product and could only increase the chance of foundation-building by 20%.
