"Lilith, protect the emir." Ophelia shouted, then rushed out.

"I understand."

Lilith hastened to protect the Emir under her wings, leaving only a gap for him to observe the battlefield.

Those monsters can't be seen with the naked eye, but they can be detected by using magical perception, and after Ophelia became an elf, she has a strong magical perception, and can even distinguish between each detected individual.

Immediately after, her ordinary long sword was instantly unsheathed and slashed towards the empty place, and a monster immediately appeared in shape, but its body burst and died.

Ophelia withdrew her blade and swung her sword behind her, and in the next second, another monster was slashed to the ground.

It was about to attack by relying on its stealth just now, but it didn't think that Ophelia could clearly perceive its existence.

At this time, the lighting tools were useless, and she simply closed her eyes, only to find that the location of the monster was clearer.

She rushed into the group of monsters with all her might, because there were so many of them that she could kill them with a swing of her sword.

They didn't seem to know how to hide, and instead swarmed towards Ophelia.

"Hmph, since they are all sent to the door, then you're welcome."

She smiled and swung her longsword at a faster rate.

Although the emir couldn't see the monsters, every time a monster was hacked to death, it would appear, so from his point of view, it looked like Ophelia had summoned the dead monsters.

Gradually, she turned around the battlefield, like a meat grinder, and everywhere she passed was the stumps and severed arms of monsters, and dark green blood gushed out like a spring, and finally gathered into a trickle, spreading to the surroundings.

Emir thought to himself, just now he said that he should come up with the perfect countermeasure, but looking at this kind of posture, let alone thousands of monsters, even tens of thousands of them would have to die under Ophelia's sword.

And those monsters were not afraid of death, and in the face of Ophelia's rapid attack, not only did not retreat, but kept flocking to her.

The reason why Emir can see it is because the corpses of the monsters around Ophelia appear more and more frequently, and the injuries are getting worse and worse, and even one monster has been directly chopped into meat sauce.

However, only Ophelia knew that these monsters were powerless, and they didn't flinch because there was nowhere to retreat.

Ophelia's place was relatively empty, but it was still difficult to accommodate thousands of monsters, they followed the killing instinct and poured out of the nest, but they did not expect to encounter hard bones, not only knocking teeth, but also making themselves prey.

They tried to escape, but found that they couldn't, and all the monsters were huddled together, only to be torn to pieces by Ophelia's sword.

After a while, the entire battlefield was covered with fragments of monsters, and the stinking blood was everywhere, even Ophelia's face was stained with a lot.

Her long silver hair turned dark green as a result, and half of her face was covered in the blood of monsters, some of which even ran down her head, blinding her.

She never carried a handkerchief, and she couldn't wipe the blood off her face at this time, so she could only wipe it casually.

She found that she had been fighting for a long time, and the number of monsters had not decreased much, but she was a little exhausted.

She would be exhausted if she continued like this, so she could only pin her hopes on Emir, and as soon as she thought of this, she looked towards Emir's side, only to find that she was also being attacked by monsters.

Although Lilith has magical perception, she can only detect the monsters gathered around her, and does not know the specific movements of each one.

In other words, if multiple monsters attacked in all directions, she didn't know how to resist them.

If the target was far away, she could still spit out dragon breath and burn them to ashes, but now the monsters were all crowded over, very close to her.

She could even feel a few of them crawling on her, and if she used the dragon's breath at this time, it would definitely affect the emir.

In addition, the wings were to be used to protect the emir, and she could not create a strong wind to blow the monsters away, so in desperation, she simply put on a defensive posture and let the monsters attack.

Thanks to the blood of the elves, the scales of her whole body have recovered, and at this time she has become an indestructible iron wall.

Because of this, Ophelia did not worry about the safety of the emir, she wiped the blood from her face, and then put on the helmet that had been hanging around her waist.

Although this will limit the line of sight, in the face of these invisible monsters, the vision is already unreliable.

After taking a deep breath, Ophelia rushed into the monster horde again, this time with a more aggressive move, no longer with ordinary stabs and swings, but with her blade slapping the monsters' bodies.

Although it seems to be less powerful, in fact, the monster that touches the blade bursts all over and dies in an instant.

Because she used the sword skills she was proud of, she didn't even have a charge, and the release of the sword skills was instantaneous, and the consumption of physical strength was also quite low.

After a while, the number of monsters has been reduced by half, and they finally have a chance to escape, but Ophelia does not intend to let them go, and with the help of her powerful sword skills, she can kill these monsters as easily as chopping melons and vegetables.

However, the situation of this battle was still unknown, because with her eyes closed, what she didn't know was that the blood that flowed from the monster's body began to evaporate into a dark green mist after a few minutes.

The Emir was looking at the battlefield through the gaps in Lilith's wings, and the crystal balls for lighting made it look obvious.

He subconsciously felt that the mist was poisonous and wanted to warn Ophelia, but because it was too far away and the monster's screams were extremely sharp, his voice couldn't be heard at all.

"Damn."

Emir scolded angrily, hating himself for being so incompetent, he knew very well that if Lilith hadn't scrupled about him, he would have burned the monster to ashes in a single breath.

At this point, Ophelia seemed to be red-eyed, unaware of what was happening around her, as her magical perception could not detect the mist.

Although her sword skills do not require much physical strength, they can still be a burden on the body when used for a long time, but fortunately she can also use magic that strengthens her physical strength, so she can still fight like this for another half an hour.

It's just that just now, it was possible to directly tear monsters to pieces like a meat grinder, but now it's different, because the movable space has become larger, the monsters have become more scattered, and Ophelia needs to take a few more steps every time she kills them, so the efficiency will be greatly reduced.

So she began to worry about whether she could kill them all in half an hour, and although she pinned her hopes on the emir, she had to be prepared to kill all the monsters on her own, just in case.

……

As time went on, Ophelia somehow felt a little dizzy.

She thought she was too tired, so she decided to stand still and rest for a while, anyway, the monster was not very aggressive, but the more she rested, the worse her dizziness became.

"Cut, are you going to make the old mistake again? It's really going to pick the time. ”

However, after thinking about it for a while, she suddenly realized that something was wrong, and her old problems did not include dizziness.

This hindsight also made her realize that her thinking seemed to have become dull.

She quickly opened her eyes, trying to see her situation clearly, but she was startled by the sight around her, and she found herself shrouded in a thick fog.

With each puff of the mist, she felt an impact on the inside of her brain, small but dizzy.

"I see, that's what you're capable of."

Ophelia suddenly realized, she turned her head, and she could no longer see Lilith, only vaguely see the light from the crystal ball piercing through the mist.

She had no intention of fighting, so she hurriedly followed the light, trying to get back to the emir as soon as possible, but after walking for a while, she found that the whole fog had scattered light, and it was the same in any direction, and she knew that she was lost.

"Hey, Emir, can you hear me?"

She shouted in one direction, but even she could hear it, and the sound grew smaller and smaller as it diverged outward, and finally dissipated into the mist.

She decides to use her magical perception again, so that she can know Lilith's location and find the Emir by the way.

However, after a period of probing, she couldn't help frowning, because she couldn't find any trace of Lilith at all, and not only that, but under her magical perception, all the monsters around her disappeared.

There is no doubt that it must be the influence of these mist, which is produced by the evaporation of the monster's blood, so naturally it can't be a good thing, and maybe inhaling too much will be life-threatening.

Therefore, she must get out of her current predicament as soon as possible.

On the other side, the emir was also shrouded in mist, and at some point, the monsters around them stopped attacking them, but they were obviously very close, but they couldn't see each other.

Emir had also tried to shout loudly, after all, Lilith was beside him, and he must be able to hear it, but the result was much to his disappointment, he did not expect the fog to be so powerful.

However, he quickly had an idea, and took Lilith back through the ring, and in the next second, a red beam of light burrowed into the ring, and then, he planned to summon Lilith in front of him again, so that he could definitely see it.

As a result, he only saw a red light fly out, but he still couldn't see Lilith's figure, which made him think that maybe his senses were blinded.

In short, no matter what he did, there was only a dark green fog in front of him, and the light that shone through the mist.

However, looking at those rays, he suddenly figured it out.

“…… Is it only light that can penetrate it? ”

Although he thought of this possibility, he could not confirm it, and it was not enough to see the red light when he retrieved Lilith.

But in any case, since he can see the light around him no matter which direction he goes, it at least means that he is still within the range of the crystal ball.

He suddenly remembered that Ophelia had thrown crystal balls at the beginning of the battle, four in total, in four directions.

Then, based on the existing information, we can know that he should be in the original position, but no matter where he goes, he is just standing still.

He had seen a similar phenomenon in a book, it seemed to be called a ghost hitting the wall, once a human was walking on the road, and suddenly found a large amount of fog in front of him, he was trying to retreat, but it was too late, he was already shrouded in the spreading fog, no matter where he ran, he couldn't run out, in fact, those fogs were just hallucinations, he was just standing still, because his senses were blinded, thinking he was running.

In this way, the situation faced by the emir is exactly the same as described in the book, and it also tells the solution, which is to move forward with your eyes closed, and finally you can get rid of the ghost wall.

I don't know if it's useful, but there's no other way but to try.

So, he closed his eyes and took a step forward, and he didn't know how long he walked before him before he opened his eyes, and the sight before him surprised and delighted.

He had indeed escaped from the fog, and he was still surrounded by Lilith's wings, and the monsters around him were still attacking them.

In order to protect her weakest point, Lilith closed her eyes the whole time, huddled in a ball, so she didn't know what Emir had just experienced.

In fact, the fog formed by the evaporation of blood is not thick enough to obscure the vision.

But it's hard to say when inhaled into the body, and Emir finally understands that this should be the ability of these monsters, creating illusions through mist, but it is a passive ability, which is only useful when bleeding.

At this point, he looked at Ophelia and saw that she was standing still, as if she was also hallucinating.

Seeing that she couldn't move, the surrounding monsters all relaxed their vigilance, and even directly lifted their invisibility and approached her one after another.

Emir secretly screamed that it was not good, although Ophelia's armor had a high defensive performance, but in the unconscious situation, the monster had every chance to unravel that armor and then attack.

It's just that he can't protect himself at this time, and if he rashly goes out from under Lilith's wings, he will definitely be killed by invisible monsters.

“…… Am I going to watch her in danger? ”

The Emir asked himself, knowing that if it weren't for Ophelia, he would have been destroyed along with the town of Blackpool.

He owes Ophelia his life, but he is ashamed of his weakness when he allows his savior to be killed by the monster while he cowers under the dragon's wings.

Then, I don't know if it was a hot head or something, he had rushed out before he realized his actions.

Lilith on the side realized that his life was in danger and hurriedly called him.

"Come back, Emir."

But he is already out, how can he retract it? If he did, would he still be human?

The monster soon noticed his presence, and because it didn't know what his strength was, it hid again and attacked him.

Faced with the ensuing danger, the emir unconsciously clenched the piece of paper in his hand, probably out of nervousness.

Immediately afterward, a pale green light burst out of it, and the emir looked at the battle and guessed that the magic on the piece of paper had been released.

In the next moment, he felt a sudden deathly silence around him, not only his voice, but everything in his sight fading, and finally he was completely engulfed in green light, and he fell into a coma.

I don't know how long later, when he woke up, it was already dawn, and he was lying on the ground.

He quickly got up and looked around, and could see Ophelia lying on the ground not far away, but other than that, everything around him was gone, including the stumps and severed arms of those monsters, the mist from the evaporation of blood, and the houses in the village.

After being stunned for a long time, the emir unconsciously stretched out his hand and found himself holding a small piece of paper.
