A large city with a population of one million, Yutian Town, Yanziwu, etc. are all under the management of this city.
The base camp of the Demon Suppressing Guard in the southeast of 'Bian Kingdom' is located in the west of Baoguang City.
A circular three-story fortress covering an area of dozens of acres.
All buildings are made of blue stones mixed with glutinous rice juice, and a cone cannot be inserted into them.
Every stone is covered with dense restrictions, and there are several large thunder towers surrounding it that shoot out thunder from time to time.
There is not a single building within three hundred feet of the Demon Suppressing Guardhouse, it just stands there all alone.
At this time, the door of the guardhouse was open, and from time to time, demon-suppressing guards in splendid clothes came and went to do business.
As for the guard station, there are one guard post every three steps and one sentry every five steps. The security is extremely tight.
The governor here is named Li Xianzong, who was born in the Bian Kingdom.
Therefore, even if his rank is one level higher than that of Bai Kun from the suzerain country, he must be treated as an equal.
What's more, Bai Kun's inspection department comes from the Lan Kingdom and has great autonomy over the thirty-seven vassal states under it.
That is to say, when facing Weng Shaochun, who also came from the Lan Kingdom, Bai Kun showed a respectful look.
Today, in a three-story building at the core of the Demon-Suppressing Guard, the largest set of rooms on the ground floor is now occupied by Zhang Ke.
This was originally a small martial arts arena, where people in the guard used to practice their martial arts.
As soon as Bai Kun arrived, he directly ordered that this place be designated as a forbidden area and renamed the 'Central Courtyard', and no one was allowed to enter or leave.
The reason why this place was chosen is because it is the closest to the ‘Jiage Library’ and is suitable for Zhang Ke to search and retrieve various information.
...
This morning.
Bai Kun and Li Xianzong chatted and laughed as they came to the entrance of the central courtyard. Outside the closed door, two Jindan masters were waiting.
One of these two people is a subordinate of Li Xianzong, and the other is a subordinate of Bai Kun.
Seeing Bai Kun and others approaching, the two real people guarding the door raised their hands and saluted.
"I've seen the envoy Li Zhen and Commander Bai!"
Bai Kun waved his hand and asked:
"Is Master Wanxiang still inside?"
Bai Kun's subordinate replied:
"In the past few days, Master Wanxiang has never left the Central Academy except to search for files in the Jiage Library."
Li Xianzong smiled "haha":
"It's rare for this Wanxiang master to be so serious about his work, but I would like to get to know him."
For Li Xianzong and others, they are monks first, and then their respective duties.
Therefore, monks of the same rank are not always treated as subordinates.
Li Xianzong was also a little curious about Wanxiang Zhenren.
The battle that took place more than half a month ago has now spread throughout all the vassal states of the Lan Kingdom.
The name of Wanxiang Zhenren also became known within the Demon Suppressing Guard along with Weng Shaochun's request for merit.
Before Zhang Ke entered the Central Academy, he made it clear that non-essential matters should not be interfered with, and multiple restrictions were opened by him.
Therefore, anyone who wants to enter must notify them first.
Bai Kun looked at the shimmering restriction on the door and said with a smile:
"I'll try to see if I can get him out."
Reach out and tap the chime at the door.
"Ding--!"
A crisp trembling sound spread into the central courtyard.
After a while, an extremely impatient voice came from the chime.
"What's up?"
Li Xianzong was slightly startled by the childish accent. How could this be the voice of a child?
When Zhang Ke came here, his body had returned to his adult form, so at this moment, Li Xianzong was a little confused.
Bai Kun looked at Li Xianzong's eyes and replied with some embarrassment:
"Wanxiang! It's me!"
After a few seconds, the restrictions on the central courtyard door disappeared one by one.
As soon as the door opened, Zhang Ke walked out.
"I don't know that Wanxiang is the commander here, I just offended you, please forgive me!"
Then he said: "When the envoy of Zhenfu comes, everything is at a loss to welcome him from afar!"
Bai Kun smiled and said:
"Fellow Taoist Wanxiang, Governor Li Zhen and I are curious about the Central Academy. Is it convenient to go in and have a look?"
"Why is this inconvenient? You two please come in!"
After saying that, he turned around and led the two of them into the central courtyard.
Li Xianzong was slightly startled by what he saw when he entered the central courtyard.
This place was originally a martial arts arena, but now it has completely changed.
In the middle is a sand table model of the area that has been reduced hundreds of times.
There is a small wind chime hanging on each of the four corners of the sand table model.
There are screens all around.
There are countless handwritings densely written on these screens, and Youde screens are also painted with patterns and various lines.
Li Xianzong made a rough count and found that the number of screens was at least over 600.
Looking carefully, Li Xianzong discovered that everything on the sand table or the screen seemed to be moving.
this......
Li Xianzong looked at it for a while, feeling like he understood something, but he didn't seem to understand anything.
He turned around and asked:
"Fellow Taoist Wanxiang! What are these used for?"
Zhang Ke's biggest gain from coming to the Central Territory is that he has perfectly integrated the talismans with the art of painting, taking his talismans one step further.
What you see in front of you is just an insignificant part of it.
"This is a behavioral trajectory model that I constructed based on some data. Its purpose is to detect special trajectories."
Li Xianzong was somewhat understanding at first, but when he heard Zhang Ke's words, he became a little confused.
Zhang Ke continued to explain:
"Simply put, this is a method of identification.
For example, there is a person who is active in a small town every day.
So what does it mean if one day he suddenly leaves the town?"
Li Xianzong blurted out:
"There must be something that requires him to leave the town."
Zhang Ke nodded and said:
"That's exactly what prompted him to leave town.
This model plays such a role.
First find some suspicious people, record their behavior trajectories, and then find some special nodes."
Li Xianzong suddenly understood and looked at the model and screen in front of him with some shock.
"Then...these??"
Zhang Kedao: "Based on some information I found recently, I marked some suspects.
We can focus on finding which of these people are special suspects."
Li Xianzong said with some confusion: "Is this accurate?"
He couldn't help but ask questions. After all, people have thoughts, and any behavior can happen.
Zhang Ke shook his head and said:
"Of course it's impossible to be absolutely accurate. This behavioral trajectory is like a net, it only plays a role in filtering and screening.
Maybe it won't help us find the problematic people, but at least it can help us eliminate some irrelevant people."
Li Xianzong was shocked and instantly understood Zhang Ke's intention.
It's like a sieve, sifting over and over again until those with problems are screened out.
In an instant, Li Xianzong thought of dozens of ways to use it.
I couldn't help but observe this set of models carefully, hoping to see something.
Bai Kun looked at everything in front of him and suddenly regretted that he shouldn't have brought Li Xianzong into this place.
Li Xianzong investigated for a moment and suddenly asked:
"Fellow Taoist Wanxiang! What is this formation called? And how does it work?"
There was a strange look on Zhang Ke's face under the mask.
“I named this formation ‘Eye of Heaven’, which means that the eye of the sky watches all living beings.
As for how it works, let me demonstrate it and the governor will understand. This is difficult to describe in words."
He guided the two of them to the sand table model and motioned them to have a preliminary understanding.
"This sand table is a set of formations constructed based on my 'sand painting' method.
What we see now are models of the six small towns and twenty-one small towns to which Baoguang City belongs."
"Ss—!"
Li Xianzong took a deep breath. As the supreme leader of the demon-suppressing guards in Baoguang City, he was not unfamiliar with the area under his jurisdiction.
He can clearly describe what any small town looks like and what landmarks there are.
But in his mind, he only had a rough impression.
At this moment, he felt like a giant, overlooking his territory.
Every mountain range, every river, every small town, including some villages in the corners, are all clearly displayed in front of you at this moment.
Never before had he had such a clear understanding of the area under his jurisdiction.
At this time, on the sand table, different appearances were displayed everywhere.
It was windy in some places, raining in some places, and even flames suddenly appeared in some places.
In addition, there are countless little people moving around, each of which has a numerical number.
Looking at the sand table in front of him, Li Xianzong felt in a daze that he seemed to see a small country in motion.
Bai Kun stared at all this in stunned silence and asked:
"Is the environment here really consistent with reality? But how is this possible?"
Li Xianzong also had this question and turned his attention to Zhang Ke.
Zhang Ke smiled bitterly and said:
"If I said that I don't understand what's going on, would you believe me?"
Without waiting for the two to ask questions, Zhang Ke continued:
"Actually, my original intention was to build a sandbox here covering all areas of Baoguang City.
Then, from the files in the guardhouse, some specially marked people were found and their movement trajectories were listed.
I want to find out some news about the evil cultivators of the 'Red Robe Society', but..."
Having said this, Zhang Ke paused and said:
"I didn't expect what would happen. When I was building this set of models, countless inspirations burst out in my mind.
It seemed that there was a strange force pushing me to move, and it gradually overlapped with the sand table. When I woke up, it looked like this."
Li Xianzong and Bai Kun looked at Zhang Ke blankly.
It’s noisy!
Are you kidding us?
But when the two of them thought about it carefully, they felt that there seemed to be nothing wrong with it.
They have also heard of this special state.
Enlightenment!
This is an extremely rare insight that often brings great improvement to practitioners.
Zhang Ke continued:
"As for some of these celestial phenomena, I don't know if they are really consistent. It's better to find someone to check them out."
As he spoke, his eyes were fixed on a certain flame above the sand table.
A flash of light flashed from the fingertips of his right hand, and he pointed at the location where the flame appeared.
"rustle--!"
In an instant, a cloud of fine sand suddenly flew out from where the flames appeared, rolling and spreading.
If the location where the flame appeared was only the size of a date at the beginning, then the date has expanded hundreds of times.
Li Xianzong was even more shocked that this formation could actually enlarge a part of the area.
At this moment, Li Xianzong made up his mind.
No matter what, I must keep this formation, its effect is really too great.
