Lin Yu's first cultivation was the Demon Pupil in Demon Slaying, because if she wanted to slay demons, she had to be able to see the demonic energy, and she herself could sense the fluctuations of external energy, but she couldn't see it just by induction, but after cultivating the Demon Pupil, she could see the demonic energy with her eyes.

Lin Yu has secretly rejoiced more than once that the magic of the flower and plant elf body, her body is still a green lotus, and the spirit body can also be freely integrated into the body, but the spirit body is like an independent individual, can walk, can eat and drink, and even the eyes are the same as ordinary people, but she can't leave the body too far, so she can practice this pupil technique.

It is difficult to say that the Demon Pupil is difficult to say, and it is simple to say that it is simple, mainly depending on the degree of control of the cultivator's mana, and when using it, the mana can be run to the eyes, and the mana can be condensed in the eyes.

The runes are not more difficult than the runes that Lin Yu has seen, but because they need to be condensed in the eyes, they need to be more delicate than when cultivating flying flowers, so they are a little troublesome, but after this period of practice, they have become much more proficient, and they can initially cultivate and condense runes.

Lin Yupan sat on the bed, the mana in the green eyes was as thin as a gossamer slowly outlined a rune, the rune was shaped like a pupil, if an outsider came to see, he could see that her green eyes were inlaid with cyan pupils, like double pupils, strange and beautiful.

Lin Yu got up and blinked, the world in her eyes had changed greatly at this time.

The air seemed to be filled with a light gray substance, very subtle, but everywhere, as if it had covered the world with a veil.

Lin Yu was taken aback, and thought that she had failed in her cultivation, but she quickly reacted that the light gray matter she saw was demonic qi.

Soon she went out and climbed onto the roof, and at a glance the whole world seemed to be light gray, and everything was full of demonic energy.

Hiss, Lin Yu gasped, feeling that his legs were shaking a little, just looking at the information that there was a residual demonic qi in the Yellow Sand Realm, it really didn't have any real feeling, just like hearing that there was a bomb left during the war in a certain place, it didn't seem to be a big deal, but seeing it with his own eyes was different, it was simply scary, was it really okay to have demonic qi in all places?

According to the information, demonic energy is a kind of negative energy, no matter what kind of living beings, once they come into contact, they will inevitably be slowly infected, or they will become irritable and irritable, or they will be cruel and bloodthirsty, and eventually become irrational beasts.

But soon she calmed down, because wasn't she given the task of reshaping the town? Moreover, the main task completed by that immortal is to reshape the world, and it will surely purify all the demonic energy in the Yellow Sand Realm.

She then went to patrol the town to see what effect the demonic energy had on the townspeople, after all, it was useless to just guess, and only by seeing it with her own eyes could she know what the truth was.

Lin Yu happened to have a person passing under the earthen house, it was a middle-aged woman, Lin Yu recognized her, she was also Lin Yu's neighbor, she lived nearby, she was a diligent person, and she often went to the fields to work after settling down in the town.

Lin Yu looked at her, this woman was surrounded by demonic energy, but the demonic energy did not change.

No, Lin Yu's eyes condensed, and he saw that it was abnormal, the pattern at the center of the woman's eyebrows was abnormal, and the demonic qi close to the pattern was more active, and the pattern was absorbing demonic energy!

Lin Yu carefully observed the pattern, the pattern was dim, but this didn't seem to be inherently dull, but because the pattern in the center of the eyebrows absorbed the demonic energy, and the demonic energy was stored in the pattern, so it was like this.

She searched around for people, checked the movement of the eyebrows of the people in Bingli Town, and found that the woman's eyebrow patterns were not an exception, but the situation of everyone, regardless of men and women, young and old, the patterns on the eyebrows were slowly absorbing demonic energy.

Lin Yu's heart was in turmoil, she didn't know whether this change was good or bad, and most importantly, she had no way to solve this matter, she could only watch the townspeople walk into the unknown direction.

If this is a good thing, if this is the demonic qi eroding the townspeople, even if the impact is not big for a while, after a long time, something will definitely happen, and isn't this just like the information said that the heavenly demons quietly infect the phantoms, making the phantoms slowly irritable, and finally break out into disaster?

"No, I have a way, there is not only a peep in the magic spell, but also the Mind Fixing Technique and the Demon Slaying Light, as long as I practice the rest of the part, I should be able to fix the demonic energy of the townman's eyebrows, and even use the Demon Slaying Light to dissolve the demonic qi in it, I think this is also the reason why the Heavenly Immortals passed down this spell."

Lin Yu's expression finally eased, and after discovering that there was demonic energy everywhere, the faint uneasiness in her heart disappeared, after all, the demonic energy described in the information was too serious, which made her feel too much crisis, and she was a little at a loss in her heart, and now she remembered that she had already made arrangements, so she didn't panic so much.

She was also in no mood to experiment with the newly cultivated Demon Peer Pupil, so she decided to go back and practice the other parts of the Demon Slayer first, otherwise she would really have no bottom in her heart, and she would always feel insecure.

After returning to the residence, Lin Yu dispersed the peeping demon pupils, and kept maintaining the spell too mana, and there was always gray demonic energy floating in front of her, which felt like dust everywhere, knowing that the demonic qi had no effect on her, but it was weird.

Time passed in a hurry in Lin Yu's concentration on cultivation, and in a blink of an eye, she had been living in Bingli Town for half a month, in addition to cultivation every day, she only patrolled the town once, and even the mayor of the town seemed to be busy with things, so that Lin Yu hadn't seen him much, and the town was calm.

Of course, she doesn't have to encounter anything, if she can complete the task calmly, there is nothing wrong with making the town peaceful, and the years are quiet, wouldn't it be beautiful.

It's just that where there is demonic energy everywhere, it is so calm, it is really weird, it makes her a little uneasy.

"The messenger is here?" Maybe she wanted to come to something, she was quiet for a long time, and someone outside the door came to look for her, not Mayor Qin.

In fact, although everyone knew that she lived here, the messenger, but except for the mayor who would come to her, the townspeople had never come to look for her, according to Mayor Qin, they didn't dare to disturb her, so Lin Yu was quite curious about this person's intention.

"What? Mayor Qin is missing? Anyone else is missing besides him? After inviting this person in, the news brought by the person startled Lin Yu.

The person who came was a young man, it seemed that his name was Qin Run, if she remembered correctly, he should have lived near Mayor Qin's house.

He was a little nervous, and he was a little restrained when he spoke to her, "Yes, there are few things in the town, and there are many things that have to be bought in the town, but it will be dangerous to go out alone, so the mayor of the town takes us there every once in a while." ”

"The day before yesterday was already the time to go to the county on weekdays, we went to look for the mayor but found that he was not there, thinking that he had something to do, but the mayor has not come back today."

"Did Mayor Qin not come back for a few days before?" Lin Yu asked with a slight frown.

Qin Run shook his head and said, "As far as I know, since I was divided together and settled here, there is wasteland all around, there is nothing but demon spirits, few people will go out by themselves, and the mayor of the town has always asked people to go out with him." ”

Could it be that she guessed that the demon spirits that might exist were real, and she also silently took away the mayor who had cultivated in her body?

When Lin Yu heard this, he knew that Qin Run didn't know much, so he couldn't ask anything, so he didn't say more, and simply took him out to find clues.

There are already people in the town looking for Qin Liyuan and the missing people everywhere, but there are not many people, it should be the people who should have gone to the county with him to buy things, as well as the families of the missing people.

Lin Yu thought for a while and said to Qin Run, "You let them go home first, and leave the matter to me." "If it's a hidden demon's smart hand, these people are just delivering food outside, so it's better to go back first.

Seeing Qin Run go to spread the word and persuade the townspeople to leave, Lin Yu's expression became serious, she had to find the reason and solve all the hidden dangers.

Another cyan pupil appeared in the green eyes, and the world in front of him was covered with a layer of gray, and Lin Yu searched along the streets and alleys with a peep pupil.
