"Second sister, are you looking for me?"

Gu Xirou looked at the purple-clothed woman in front of her and whispered.

The woman in purple turned around, glanced at her, and said with a smile: "Well, I have something to look for you!"

"What's the matter?"

"Don't be in a hurry, sit down and talk slowly!"

The woman in purple closed the door as she spoke, and specially patted it lightly on the door, this action was seen by Gu Xirou, she was awe-inspiring in her heart, what did the second sister mean to say that the wall has ears?

"Third sister, do you remember when your father handed us the illusion technique?"

Gu Xiyuan walked to her place, then sat down, and glanced at the roof very casually, Gu Xirou followed her to take a look, the air was mixed with strong sandalwood, which interfered with her ability to identify enemies by smell, but she still found that there was something different on the roof, as if someone was eavesdropping on the roof.

"Yes, remember!"

Gu Xiyuan's words were said with the illusion technique, so Gu Xirou also answered her in the same way!

Sound is generated by vibration and then transmitted by causing the resonance of the medium, but the illusion technique does not use this principle, but uses the transmission of ideas, and people who are not proficient in this way cannot hear their voices at all.

"Second sister, someone is eavesdropping, do you want me to arrest him!"

"No need, it's inevitable to come here and be watched, there's nothing to make a fuss about, how did you do what you were asked to do before?"

"It has been investigated clearly, this matter was done by Wan Jie, the eldest young master of the Wan family in Dongliu City, and the ice prism that flowed out of their auction house can basically confirm this, but whether those changes in Anlan City are related to the Wan family, this is not very clear!"

Gu Xirou frowned slightly, this time they went to the Ten Thousand Demon Country, ostensibly to participate in the Long Live Celebration of the Demon Emperor of the Ten Thousand Demon Kingdom, but they actually had another purpose, that is, to investigate the inside story of the serial murder case in Anlan City!

The series of murders that occurred before Anlan City were originally just a matter of the Criminal Department, but then things began to escalate, and several big men and generals were killed at home one after another, which caused the shock of the court, and the emperor entrusted the matter to the Demon Slayer, because from the traces left by the perpetrator of this case, they judged that it was not simple at this time, because it involved the monster that the Demon Slayer had wanted for many years - the Green Bull Monster Han Xianhu!

Han Xianhu is a demon who kills people without blinking, and he is a monster who has cultivated into a spirit, a monster like him should have lived in the country of ten thousand demons, but I don't know why, he ran to Anlan City, and that's it, because there were no monsters coming to Anlan City before, so it didn't attract much attention at first!

But soon, this person began to commit crimes in Anlan City, in just two years, Han Xianhu committed dozens of large and small cases in Anlan City, these cases are generally tragic cases, so it caused Anlan City's fear of monsters, and the relationship between the human race and the demon clan also fell into the freezing point because of Han Xianhu's relationship!

In order to restrict the activities of monsters in Anlan City, Anlan City began to implement a registration system, which will register and evaluate the monsters entering the city to evaluate their strength. The purpose and responsible person, if one of these three is not qualified, then they are not allowed to enter the city, which is the reason why Xuan'er was targeted by the Gu family brothers and sisters in Anlan City at the beginning, in Anlan City, after the implementation of this decree, the number of monsters has been greatly reduced, and the remaining monsters are all monsters that have a guarantor and do not do much harm, and suddenly see a strange monster, they are naturally very suspicious!

Han Xianhu's last crime was to attack a convoy, on the surface, this is just an ordinary case, but the person involved in this case is more important - Sun Heng, the Shangshu of the Criminal Department.

Gongsun Heng was attacked on the way home, and then assassinated, it doesn't matter, a large number of confidential documents he carried with him were also taken away, and more than 50 guards of Shangshu Mansion also died this time, the last time on the Absolute Ridge, they dealt with this case.

Han Xianhu's skills and whereabouts are strange, Gu Xirou has followed him for more than two years, and has fought several times before and after, but he has not been able to successfully arrest him, and he has never found too many clues!

But this time, Gongsun Heng brought his concubine with him when he went home, and he got an ice prism from the hands of Wang Jinghuan, the young master of the Wang family, this ice prism is one of the nine ice prisms in Anlan City, he and his concubine were killed in this attack, but this ice prism disappeared!

And a month later, at the auction site of Wanjia in Dongliu City, two ice prisms suddenly appeared, and this incident immediately attracted the attention of their demon slaying guards, because one of these two mirrors was the one that Sun Heng, the Shangshu Gong of the Criminal Department, had lost.

So, this time, following the opportunity for the empire to send an envoy to celebrate her birthday, Gu Xirou and her second sister came over together, wanting to investigate this matter clearly!

There was a voice from the top level of the central and central government of the DPRK, saying that Han Xianhu's actions were funded by the Ten Thousand Demon Kingdom, and the purpose was to destroy Anlan City internally, destroy the ruling foundation of the human race, and prepare for their next invasion!

This statement is similar to some kind of conspiracy theory, and it is not very credible, but it has aroused the high level of vigilance, and this time they went to Dongliu City to find out about this matter.

"Whether it's or not, we have to investigate carefully, you and I have limited mobility, and I have already asked people to investigate secretly!"

When Xi Yuan spoke, a smile appeared on the corner of his mouth, and the people on the roof may have found themselves discovered, so they had quietly left at this time.

This person's skills should not be bad, otherwise she wouldn't have quietly lurked on her roof so that she didn't notice, if she hadn't deliberately slapped the lintel when she closed the door before, and judged that there was someone on the roof by the sound of the lintel vibrating, it was very likely that the conversation between them would have been overheard by this person!

However, what is the origin of this man?

Is it a member of the Ten Thousand Demon Kingdom, or a member of the Mission?

It's a pity that I can't figure this out.

"Second sister, what are we going to do these days?"

Gu Xirou was a little surprised, if she wasn't allowed to deal with this matter, why did the second sister ask her to go to Wanjia to investigate the matter before?

Isn't this a scareless snake?

"Hehe, I heard that there is a Korean-style shop in Dongliucheng, if the third sister is interested, you might as well take a look, there are a lot of strange things for sale over there, I think you should be interested!"
