Ruiguang City is more than 100 miles away, and it will take a few hours to arrive. From a distance, Ruiguang City is not grandiose, it is a small city. The walls are only two or three meters high, but they are very thick, which is also used to protect against wind and sand.

There were already guards who entered the city to report, and Ma Zhongxin, the city lord of Ruiguang City, personally went out of the city to greet him. Ma Zhongxin was a monk who had perfected his Qi refining, tall and handsome, and looked a lot like a half-blood on Earth.

"Welcome, welcome, Wang Daoyou is finally here!" Ma Zhongxin said with a smile. His voice is very magnetic, and his smile is also very affinity, which reminds Wang Yicheng of male movie stars on the earth.

"This person is very attractive, he should be very pleasing to women!" Wang Yicheng looked at Ma Zhongxin and said secretly in his heart.

Ma Zhongxin led Wang Yicheng's carriage into Ruiguang City, which has a population of 20,000 and is quite prosperous with people coming and going, obviously not affected by the plague. The liquor shops on both sides of the road are also open for business. Most of the pedestrians on the street wore white robes, white hats, and veils to cover their faces, which was used to protect against sand and dust.

Ma Zhongxin arranged Wang Yicheng and his party in a courtyard of the City Lord's Mansion, and his City Lord's Mansion was far worse than the Jin family's Mansion in Jinshan City. There are only a few courtyards, and the decoration is relatively simple.

The yard where Wang Yicheng lives has been calculated, and there are pond rockery dwarf trees. But the water in the pond has dried up, and the dwarf trees have withered. The furnishings of the hall and rooms are even simpler.

"Alas, I've always been worried about the plague nearby, and I can't even take care of my own mansion, which makes Wang Daoyou laugh!" Ma Zhongxin apologized again and again.

"The lord of the city was worried about the people, and he ran around outside the city every day, and even his hair turned gray. The young guard on the side interjected.

"My generation cultivates immortals, what we cultivate is righteousness, helping the needy, and caring for the people is our duty, what is there to work hard. Ma Zhongxin said solemnly.

Jiang Lan and Hou San both nodded and secretly praised, they were used to seeing the cruel and murderous monks of the Niu family, and they were very moved when they saw a righteous person like Ma Zhongxin. Among the monks in the cultivation realm, there are naturally bad people and good people.

"How many people have died from this plague, and I see that many villages have died?" Wang Yicheng asked.

"The number of people who died, at least more than 10,000, was a disaster. Ma Zhongxin said with a sigh.

"The letter you sent to the sect said that you suspected that there was an evil spirit. But what a clue. Wang Yicheng asked again.

"Yes, I found these things in some villages. After saying that, he waved his hand to the guards next to him, and immediately several guards took out some broken stone slabs and some tattered flags and placed them on the ground in the middle of the hall.

"Formation!" Wang Yicheng is now studying these things every day, so he is very familiar with them. He walked over, crouched on the ground, and pieced together a few stone slabs, studying the patterns on them.

"This is the Soul Collecting Array, which can automatically collect all the souls within a radius of several hundred meters. Wang Yicheng said.

"Hey! Wang Daoyou is also proficient in formations, he is young and knowledgeable, which is really admirable!" Ma Zhongxin originally wanted to explain the role of these formations to Wang Yicheng, but now he has saved a lot of tongues.

"These things have been found in several villages, and it is clear that the demons have deliberately created a plague to kill these people and refine their souls. Ma Zhongxin said affirmatively.

Wang Yicheng nodded, if these things were really found in the village where the plague occurred, then the evil demons were doing the trick.

"Any clues?" Wang Yicheng asked.

"Hmm!" Ma Zhongxin nodded, "After these days of investigation, I have found some clues, but I can't be sure yet, and when the murderer is determined, Wang Daoyou will definitely be notified." ”

After Ma Zhongxin left, Jiang Lan and Hou San were full of praise for him. Wang Yicheng just smiled and said nothing, he is an agent, and what he is best at is deceiving people, so he never trusts others easily. There are too many outrageous hypocrites in this world.

After more than ten days, Wang Yicheng stayed in the courtyard and did not go out, he remembered what the Lord of Jin City warned him, don't be reckless, keep a low profile.

On this day, suddenly, Ma Zhongxin hurriedly came with a few guards and said, "I have explored the lair of the evil demons, and I ask Wang Daoyou to go and arrest them together." ”

Wang Yicheng asked Jiang Lan to stay at his residence, and took Hou San to follow Ma Zhongxin out of the city on horseback. As he rode his horse, Ma explained that his men had spotted the demons in a village, followed them to their lair, and had now laid a net around the lair, just waiting for them to go, and then hunt them all.

A few people came to a small hill and dismounted, the land in this place is seriously desertified, it is said to be a hill, more like a sand dune, the sand on the surface forms a hard shell, and there are not a few shrubs growing sparsely on it.

One of the guards came up and told him that the demon was on the other side of the dune.

Ma Zhongxin said to Wang Yicheng: "There are a lot of demons, Wang Daoyou doesn't have to take risks in person, let's leave it to us to attack the demons!"

After saying that, he walked to the other side of the sand dune with the guards. After a few moments, there was a shouting sound from across the dune, followed by explosions and metal crashes. The sound grew denser and denser, mixed with screams. The ground shook slightly with a loud roar.

Hou San's face turned pale, and his palms were sweaty. Wang Yicheng squinted his eyes slightly, not knowing what he was thinking.

After a while, one of the guards came to Wang Yicheng, saying that all the demons had been captured, and asked him to come and watch.

Wang Yicheng took Hou San and followed the guard to the other side of the dune, only to see that the battlefield was in shambles, with many blackened explosion marks, and many guards were injured and were being bandaged.

Ma Zhongxin pointed to a hole and said, "It turns out that it is not an evil demon, but a group of demons, please see." ”

I saw many strange-looking aliens being escorted out of the hole. These demons are short in stature, only about one meter, with pointed ears, a narrow mouth, two mustaches, eyes like beans, look like roe deer, very treacherous, and a slender tail swinging behind them, and their claws and claws have sharp nails.

"Rat spirit!" Wang Yicheng probably recognized his appearance when he looked at it.

"These are gerbil spirits!" "Gerbils are rats endemic to the Land of Quicksand, and they like to live in burrows under the sand. It is much smarter than ordinary mice, and it is also easier to become sperm.

A group of guards took out a lot of things from the cave, including people's clothes, some daily necessities, and many flags and plates.

"Did you get these things?" shouted one of the guards as he put his sword on the neck of a gerbil spirit.

The gerbil spirit looked at the Xueliang long sword around his neck, his face showed fear, and he whispered, "Yes." ”

"You are the one who spread the plague and killed the villagers?"

"Yes. ”

The gerbil spirits confessed and lowered their heads.

That night, Ma Zhongxin hosted a banquet for Wang Yicheng in the mansion, the truth was revealed, and the murderer was brought to justice, which can be regarded as perfect.

"When I return to the mountain gate in a few days, I will definitely report to the head of the gate that the lord of Ma City has exterminated a group of demons, which is really a great achievement. Wang Yicheng said to the city lord with a smile.

That night, the guests and hosts enjoyed themselves, and Wang Yicheng returned drunk.

Hou San helped Wang Yicheng back to his residence, and as soon as he entered the room, Wang Yicheng's hazy drunken eyes suddenly became clear, pretending to be drunk is also his specialty, and his acting skills are first-class.

"Hou San, follow me out of the city to find out the truth of the matter. ”

"The truth?" Hou San was very surprised, "Aren't those gerbil spirits the murderers who unleashed the plague and harmed people? ”

Wang Yicheng sneered slightly, his eyes became very sharp, these are a pair of super agent eyes, there is nothing false in the world to confuse him.

Wang Yicheng took Hou San out of the city in the night. Come to the dunes where gerbil spirits are captured. Wang Yicheng walked around for a while, and suddenly pointed to the marks of some ruts on the ground, and sneered: "These are the marks of the carriage, but the guards who came today are all on horseback, have you ever seen a carriage? Their carriage has only one purpose, that is, to transport gerbil essence." ”

I went into the cave again, and the inside of the cave was very spacious, but everything was cleaned up.

Wang Yicheng sneered again, "This is the nest of gerbil spirits, they live here, why don't they prepare some food and drink supplies, they are also living beings, they always have to eat, drink and sleep, but is there a trace of life here?"

Wang Yicheng inspected the stone wall of the cave again, and sneered: "The strength of the gerbil spirit is not weak, and we heard that the fighting method is also very intense, but you see, the wall of this cave is very smooth, and there are no traces of being collided by spells." Also, in such a fierce battle, only a few of those guards were slightly injured, and this combat power is too strong!"

The more Hou San listened, the more he admired, and then he simply admired the five-body throw, why didn't he pay attention to these clues!

Wang Yicheng smiled silently, agents are good at stealing, assassination, deception and other skills, if it is the other way around, they can also become the most powerful detectives.

"Lord Ma Cheng seems to be a good person, he acted like this to deceive us, could it be that he was worried that he would not be able to explain to the high-level sect family?"

Wang Yicheng sneered, he had already guessed a rough idea, and the real culprit was in his heart, but he still needed some verification.

Wang Yicheng took Hou San back to the city, but instead of returning to his residence, he arrived in front of a tall and sturdy stone house. This is the prison in Ruiguang City, and those gerbil spirits that have just been captured are all locked up here.

There were several guards walking around the prison gate, and Wang Yicheng used a levitation technique to approach them silently. Suddenly, the palm of his hand slashed into their necks with great speed. These guards snorted and fell to the ground softly, they were all cultivators in the early stage of qi refining, and they were not much stronger than mortals, so they couldn't help but blow him.

There is a large iron lock hanging on the iron door of the prison, and there are some strange patterns on the iron lock, Hou San studied it for a while and said: "There is a miniature prohibition on this iron lock, which is used for alarms. ”
