Lin Yun followed from a distance, keeping the longest distance to prevent being discovered too close.
"At least tens of thousands of souls were absorbed just now. Do they need so many souls to refine the elixir?"
Lin Yun asked doubtfully.
"It's a bit strange. Logically speaking, unless it is refined on a large scale, souls would not be collected so aggressively."
Bai Lao is also a little strange.
"Lao Bai, you mean that these people are refining elixirs on a large scale!"
Lin Yun asked.
"No, large-scale refining requires a lot of alchemists, and the grade must be high, because refining this kind of elixir requires an alchemist to be a seven-line alchemist or above. How many of these alchemists have you seen?"
Bai Lao said.
"Let's go and have a look. I'd like to see who made such a big deal."
Lin Yun smiled and walked forward behind a few people.
After about a stick of incense, several people came to a mountain. After looking around, they walked directly into the mountain.
"How is it possible? No, it's a formation."
Lin Yun was taken aback, but quickly realized that there should be a formation inside, hiding the entrance of the cave.
"This is a bit troublesome."
Lin Yun walked towards the mountain where several people disappeared. At the same time, he activated the Tianming Eye to see if there were any formations or the like around him.
Fortunately, apart from this mountain, Lin Yun did not find any other formations, and the only formations on the mountain were at the foot of the mountain. The entire mountain was not covered with formations.
This made Lin Yun breathe a sigh of relief. If the formation was more complicated, Lin Yun would have nothing to do.
Afterwards, Lin Yun rubbed his hands and began to slowly crack the formation.
A quarter of an hour later, the two formation patterns were cracked by Lin Yun, and a gap appeared in the formation. Lin Yun jumped into it.
"It's like hollowing out the entire mountain."
As soon as Lin Yun entered, he was instantly shocked by the entire intricate tunnel.
"Oh my god, there are so many roads, which one should I take?"
Lin Yun looked confused at the tunnel in front of him.
"Boy, wait, don't release your soul power."
Just when Lin Yun was about to release his soul power, Bai Lao stopped him.
"Why? Mr. Bai."
Lin Yun asked doubtfully.
"People here collect souls most likely to refine elixirs that enhance soul power, so there must be people here who use soul power. Once you release it, it is very likely that the other party will notice it."
Bai Lao said.
"Yes, yes, yes."
Lin Yun broke into cold sweat instantly and withdrew his soul power.
"Rustling."
At this time, footsteps came from Lin Yun's left side. Lin Yun ducked and hid behind a passage, observing carefully.
After a while, four or five men in black robes came out of the left passage, all holding a gourd in their hands.
The man in black robe did not notice Lin Yun and entered the mountain through a passage in the middle.
Lin Yun used Qi Condensing Technique to the extreme, making his own breath disappear, and slowly followed several men in black robes and walked inside.
Fortunately, Lin Yun's tracking skills were good, and some of the men in black robes were a little careless and did not notice a tail appearing behind them.
After walking for about a quarter of an hour, Lin Yun was confused by the road that turned left and right.
Finally, several men in black robes stopped. They walked into a huge stone hall, which was polished very smoothly and inlaid with countless moonstones, making the entire hall look like daylight, unlike the passages, which were as dark as the passage. .
The most noticeable thing is that there are tens of thousands of small pits dug out on the stone wall, and there is a gourd in each small pit.
"Damn it, there are at least tens of thousands of gourds here. Even if each one holds ten thousand souls, there are hundreds of millions here."
Lin Yun clenched his fists.
The men in black robes placed the gourds in a small pit without gourds and then left through another passage.
"Strange, why do they put their souls here?"
Lin Yun felt a little strange after calming down.
"What's the passage at the back for? Those people seemed a little scared and didn't even look there."
Lin Yun looked at a bright passage behind and said.
"Go over and have a look."
Lin Yun came out of the hiding place and was about to enter the hall when there was another sound of footsteps.
Lin Yun immediately retracted his outstretched foot and hid in the dark to observe secretly.
The sound of footsteps approached, and after a while, a man in black robe also came out of the passage at the back of the hall. After looking around, he picked up two gourds and walked back into the passage.
"What an opportunity."
Lin Yun smiled and followed quietly, but Lin Yun also held back a hand. When passing by the hall, Lin Yun threw out hundreds of talismans and hid them behind the gourd.
"Hurry up, there are not enough souls."
After walking for a while, a person's voice came from the front.
"Is it coming?"
Lin Yun slowly slowed down and touched it quietly.
There is still a stone hall at the back, but there is only one door, and it is much smaller than the stone hall in front, but it is still brightly lit.
"Soul Palace? Are these people an organization?"
Lin Yun looked at the door of the stone hall with the words "Soul Palace" written on it.
Lin Yun was not in the mood to study which faction these people belonged to, but quietly looked inside.
But Lin Yun was a little far away, and Lin Yun couldn't see clearly what was inside.
So Lin Yun took a few steps forward and hid behind the door, and then he could see clearly inside.
A huge formation filled the entire hall, and in the center of the formation, an iron chain floated in mid-air. The iron chain was about three feet long and about the thickness of a tea cup. It was made of iron rings interlocked with each other. At one section of the iron chain , is an inverted triangle-shaped dart with two sides, and at the four corners of the formation, four men in black robes stood there, opened a gourd, and placed it there.
After a while, the formation was activated, and countless souls were sucked out of the gourd, and continued to sink into the iron chain in the air, while the runes on the iron chain continued to flash.
On a high platform nearby, sat a man in black robes who looked like their leader.
At this time, there was a sound of footsteps behind Lin Yun, and Lin Yun immediately dodged and hid.
After a while, a man in black robe hurriedly ran in and came to the high platform.
"Palace Master, people are here."
The man in black robe said to the man in black robe who was sitting.
"The distinguished guest has arrived, please invite me."
The seated man in black robe said.
"yes."
The man in black robe who came in immediately went out.
"Who is the distinguished guest?"
Lin Yun, who was hiding in the dark, was thinking.
After a while, an old man with gray hair and a childish face walked in.
"Elder Gu's visit is too late to welcome him from afar."
The man in black robe on the high platform stood up and said.
"Your Majesty, you're welcome. How about the things I asked for?"
The old man with gray hair and boyish face asked.
"Elder Gu, don't worry, in another quarter of an hour, this soul weapon will be completed."
The man in black robe said.
