Lu Qing'an instantly entered the research state, took the manuscript left by Li Ming, and began to improve it.
It took him half a day to determine the structure and some details of the formation he wanted to set up.
"Very good. With my level, five days is enough to engrave these array patterns. Even after setting them up, I'm still missing two things, otherwise I won't achieve the best effect."
These two things are the breath of the demon clan and a special array center.
The aura of the demons is difficult to preserve. The best way is to directly throw it into a demon, or any part of the demon's body, so that you can better search for the demon's location.
So, they need to capture a demon, or see if they can get a demon corpse from somewhere.
As for the special array center, the best choice is a being with intelligence, such as a spirit, or the spirit of some treasure.
Xu Qingying once said that her red vase seemed to have spirituality, suggesting that there might be a spirit hidden inside.
In addition, some elixirs, if they reach a certain grade, can also give birth to spiritual bodies.
Only when these two things are complete can his formation accurately locate the location of the demons.
"I don't have this thing yet, so I can only ask Murong Qingming to try to prepare it."
While he was thinking, he suddenly heard Murong Qingming's voice coming.
"Fellow Daoist Jia, the elixir is ready. Can you send it over right away?"
Hearing this, Lu Qing'an smiled and replied through voice transmission: "Very good, I also have something important to tell you."
Not long after, Murong Qingming arrived at his residence.
He handed Lu Qingan the storage ring containing five million worth of immortal medicine, and then asked, "Is there anything else, fellow Daoist?"
Lu Qing'an pointed out the two things that were missing from the demon-hunting formation and told Murong Qingming.
Murong Qingming frowned upon hearing this, and after a long moment of contemplation, he said, "Demon corpses or remnants of their aura can still be obtained. The Immortal Sword Sect might have them. But this spirit body is truly hard to find."
The probability of this kind of spirit existing is very small, and it can only exist in some special treasures.
For example, his puppet, unfortunately the puppet has been destroyed, and the spirit has naturally disappeared.
Some high-level elixirs that can give birth to spiritual bodies are extremely expensive.
There is another situation, that is, after human death, the soul survives through special means or special circumstances.
The probability of occurrence is also extremely small.
"I'll try my best to think of a solution." Murong Qingming frowned.
Lu Qing'an nodded slightly, then looked intently at Murong Qingming and asked in a deep voice, "I've always felt that the demons haven't left Panlong City. It seems that they want something here, and it's definitely not as simple as just human lives. Fellow Daoist Murong, is there anything you haven't told me?"
He thought about it carefully and felt that there must be some secret in Panlong City!
He was still a "Mongol" at this time!
