"Are there really so many alleys in Central City..." Pulling Kira along, Leticia quickly wove through the dark alleys of this cold district.
She had been separated from Melanie; she didn't know the reason, but the white-haired girl had indeed vanished from behind her.
A faint mist shrouded the two girls. If they concentrated, they could occasionally see a few dark shadows flashing through the mist.
"Sister, something isn't right." Kira frowned as she looked at the mist surrounding them. How could it be foggy in this kind of weather?
"I know, but I have indeed lost my sense of direction now." Leticia gripped Kira's hand tightly. This unknown situation made her gradually regain a feeling from the past.
Being able to cloud her perception, this mist was definitely not something ordinary.
Whoosh—a sharp arrow shot out from the mist, aimed directly at the center of Leticia's forehead.
Leticia's eyes constricted. Before her brain could even react, her body autonomously constructed a magic shield with complex patterns in front of her.
Bang!
The arrow hit the shield. The moment it struck, the unstable substance inside the arrow underwent an irreversible transformation under the powerful impact.
A small explosion; it didn't put much pressure on the magic shield.
"Tsk, an ambush?" Looking around, Leticia still couldn't find where the attacker was hiding.
The mist severely interfered with her perception; she could only use the most primitive methods to find her enemy now.
This feeling of being both blind and deaf made Leticia quite unhappy.
At the same time, she was searching through her memories, wondering what this mist was, that it could trap even her, a Demon King.
Ordinary illusions couldn't trap Leticia. Even an illusion released by Kira could only restrict Leticia for a few minutes at most.
But this mist had already been interfering with Leticia's perception for over ten minutes, and Leticia even felt she would be trapped for even longer.
Because, up until now, she hadn't found even a single way to break the situation.
"Sister, calm down." Kira said softly, "If I'm not mistaken, this should be 'Fog City', a long-lost ancient artifact."
"I didn't expect that there would actually be someone among humans capable of activating it."
"Artifact?" Leticia was stunned for a moment. She had heard of this term, but weren't these all just scam items?
The throne she used to sit on was called an artifact by people, but wasn't that just an ordinary big chair?
"Although I really want to tell Sister everything, this doesn't seem like a good place to talk." Looking at the white monsters gradually appearing from the mist, Kira couldn't help but frown.
These things were truly nauseating.
"Is this something that comes with the mist?" Leticia waved her hand casually, and those monsters were blown into snow-white sculptures by a howling cold wind.
"According to the records in the research, 'Fog City' only has the ability to make people lose their way. These things must have been released by the mastermind behind it." Kira shook her head.
According to the records in the research?! Didn't that book only contain some specious myths and legends? Where did these proper records come from?
Hearing Leticia's suddenly audible breathing, Kira probably guessed what her sister was thinking. "The real content of the research requires certain methods to be revealed. What you saw, Sister, was just a disguise of the research."
"Also, can't you take off your mask, Sister? I can't see your expression like this."
"It is indeed a bit uncomfortable to wear." Leticia did not oppose her sister's suggestion; she really didn't have any affection for the mask on her face.
Although it was quite pretty, having something covering her face always made her somewhat unhappy.
Taking off her hood and moving the mask to the side of her head, Leticia's expression appeared quite serious.
But Kira was not as nervous as Leticia. "Sister can rest assured. Although 'Fog City' is difficult to break, its offensive power is almost zero. Those ambushes are the work of the person activating 'Fog City'."
"And, I feel that their main target is not us."
Their main target is not us? Leticia was stunned.
Immediately, she widened her eyes. No wonder she couldn't find where Melanie was!
Who would ambush them? This answer was very, very easy to guess; it could only be that council member who had their book stolen.
The Hero Association was on their side. Leticia believed that Melanie would not reveal her identity to the Hero Association or other official human factions.
If she really did that, Leticia would accept her fate.
But now, Leticia had to admit that she trusted Melanie.
This was mutual trust between mortal enemies; this kind of trust was even purer and stronger than the trust between best friends.
"Their target is Melanie—no, it should be said, it's that book." Leticia said coldly.
"Although I thought those people would come to disrupt the transaction, I didn't expect them to have this kind of thing in their hands." Kira sighed, but her gaze couldn't help but drift towards the top of Leticia's head.
The hairpin that Sister was wearing seemed to be the birthday present she had given her.
Back then, Sister had looked at it with disdain and said her craftsmanship was bad. She didn't expect that Sister would actually wear such a hairpin.
Hmph, saying her craftsmanship was bad; her hairpin was clearly made super well!
Kira had obviously misunderstood something. In fact, Leticia was just a hopeless, trashy sister.
If it weren't for Luna's reminder, she wouldn't even have known she had such a hairpin.
"Sister, aren't you worried about Big Sister Melanie?" Kira composed herself and asked. She noticed that although her sister had guessed that the target was Melanie, there wasn't a hint of worry in her emotions.
It was as if she trusted Melanie very much and knew that the girl would absolutely not be in any trouble.
"She's very capable." Leticia rolled her eyes. Even she could easily handle these ambushes; wouldn't it be simple for Melanie to deal with them?
"Sister, who exactly is Big Sister Melanie?" Kira finally asked a question she had been curious about all along.
With such strength and a strange relationship with her sister, her identity was truly mysterious.
"With Kira's level of intelligence, you should have some guesses by now, right?" Leticia patted her sister's little head. "You and Leticia are good friends; she must have complained to you about that person with the surname York."
"Yeah, she said her sister had been away for a long time and only recently returned... recently..." Kira's eyes slowly widened. All the clues connected together, and an answer appeared in her heart.
No way? Isn't that Sister's mortal enemy?
