The fairy maid cheers for her deceased master today.

Elena and Angel gasped in shock at the same time, their emerald and blue eyes instantly filled with astonishment and disbelief.

"You mean, Spring-Heeled Jack?!"

Elena's voice trembled, her tone changing. "Sir X, please...please calm down! That monster! It is...it is..."

"It's the same mutant that attacked us before!"

Angel chimed in, her little hand gripping X's arm tightly, as if trying to pull him back from the brink of madness.

"Master, that thing can breathe fire, jump incredibly high, and has terrifying claws! And it keeps trying to attack us!"

"Should we go looking for it now? Wouldn't that be like walking into a trap?!"

Irene nodded vigorously, her emerald hair trembling slightly with excitement.

She wasn't stupid; she immediately understood what X meant. Clearly, X wanted to use one enemy to devour another… but the idea was still too crazy.

"That's right! Sir Axe. It's so cunning, so dangerous! We have no control over it! It might tear us and Sister Catherine to shreds!"

Looking into the two fairies' eyes, which were filled with both fear and determination, X knew that their concern and worry stemmed from their feelings.

But his thoughts were exceptionally clear.

"I'm not crazy."

Ex's voice was unusually calm.

"Think about it carefully, what is Jack? He is a mutant, a powerful, cunning, and... extremely hateful mutant. But more importantly, he has his own... 'rules'."

He pointed to the abandoned factory occupied by gangsters: "Those guys think this is their territory. But don't forget, Jack has only ever followed his own... 'rules of the game' since he first appeared."

"Those kidnappers thought they had everything under control. But they didn't know that the factory they occupied could also become Jack's new 'playground'."

"This...this is insane!" Elena still couldn't accept it. "We can't control Jack at all! He's a beast!"

"It is precisely because it is a beast that it is more easily provoked and more easily manipulated."

Ex smiled slightly.

He looked at the two fairies, whose faces were still filled with worry and fear, and took a deep breath:

"I know this is risky, even a gamble. But it's the only way to break the deadlock! Those kidnappers are numerous, powerful, and ruthless; if they force their way in, we're doomed. Jack, on the other hand, is the variable, the creator of chaos! It's in the chaos he creates that we have a chance to rescue Catherine!"

"Believe me. It's time for a new player to join this game. And Jack is that... 'Joker' card that can turn the tide!"

Or it's the real, literal Joker.

"Or do you think that if we don't go looking for Jack, Jack won't come looking for us?"

These casual words completely jolted Elena awake.

Angel exclaimed "Ah!" and then nodded frantically like a chick pecking at rice.

"Yes, Master, Jack will definitely come looking for us. We've been at odds with him for so long."

X held up a finger: "Who knows, Spring-Heeled Jack might still be following us around here..."

These words frightened Angel so much that she quickly hid behind X and looked around.

Elena also calmed down and began to think: "You mean... we should take advantage of this opportunity to solve two problems at once?"

"Yes. What if Jack suddenly appears while we're rescuing Catherine? We'll be in a passive position. We need to turn the tables and take the initiative."

"What should we do?"

"Actually, it's quite simple. First, we need to figure out the pattern of Jack's actions. What rules does it follow?"

"Think about it carefully, isn't there a pattern to Jack's appearances each time?"

Elena and Angel exchanged a glance, trying hard to remember.

"It seems...yes," Elena said hesitantly. "Every time it appears, there are omens. And these omens have been reported in the news many times."

“That’s right.” Ex nodded. “And there are always signs before it appears. Scarecrows, flashing gaslights, charred marks… these are its ‘rules of the game.’”

Angel's little face scrunched up: "Game rules? That monster has rules?"

"Yes," Ex said definitively. "Jack isn't an ordinary mutant. It's more like... a mischievous demon. It has its own 'rituals.' It enjoys creating panic and watching people panic."

"But more importantly, it follows the rules it sets for itself."

Elena instinctively grabbed X's hand.

"What's wrong, Elena?"

"Sir X, how can we... be sure that Jack will always follow the rules?"

Indeed, most people in London have probably heard of Spring-Heeled Jack and know his rules.

But why should it still follow the rules today? Could something unexpected happen?

"Aren't our own recent experiences proof enough?"

Ax smiled slightly, clearly having anticipated this question.

Angel immediately put her little brain to work and asked, "Ah, it's the attack from before!"

In an attempt to win over Elena's heart, X and Angel took her out for drinks. This, however, attracted the attention of Spring-Heeled Jack.

So Jack planned to attack the drunk Elena, and before the attack, he deliberately placed a scarecrow in front of X's carriage.

It was as if a notice had been sent, telling X: I'm coming.

Then, late that night, Jack appeared right on time.

The problem is that when X first encountered Jack in the Rain World, Jack didn't give any warning before launching the attack.

It could be due to the environment. But more likely, it's because this is Elena's inner world.

Once Jack enters this place, he is also influenced by Elena's subconscious and must abide by Elena's perception of him—that is, Jack must have a premonition before he acts.

That's why Jack had to throw a scarecrow first and wait for quite a while before he could launch his attack on Elena.

In conclusion, this has proven that Jack's behavior is currently restricted and must comply with people's perception of its behavioral rules.

Otherwise, given Elena's previous scare-in of Jack... X doesn't think the clever Jack needs to go to such lengths for these strange rituals.

"So..." Elena's eyes lit up, "You mean, we can take advantage of its rules?"

"That's right." A cold smile curled at the corner of AX's lips. "Since it likes to play and has to follow the rules, then we'll play a big game with it. Let it become our 'joker'."

Although Angel was still a little scared, seeing how determined X and Elena were, she nodded vigorously: "Yes! I believe in Master!"

Ax nodded and began to analyze: "Based on previous encounters and London legends, Jack's patterns of action can be summarized as follows."

He held up his fingers and listed them one by one:

"First, it likes to appear on rainy nights, okay, that doesn't count."

In a rainy world, there is never a time when it doesn't rain.

"In short, this is consistent with its characteristics and the London legend that it often appears in cold and damp environments."

"Secondly, it prefers specific 'stages.' For example, dark alleys, and... abandoned factories." His gaze swept over the factory buildings in front of him. "It likes places with a 'dramatic' feel."

Angel blinked: "This conclusion feels a bit vague!"

indeed.

X nodded slightly: "So the important part is later—"

"Third, and most importantly—it leaves a 'warning' before each large-scale attack. Scarecrows, flickering gaslights, charred marks, even anonymous letters… These are not accidental; they are deliberate. It is announcing: 'I'm coming!'"

Catherine had previously stated that the flickering gaslight, anonymous letters, charred marks, and the scarecrow were all omens that Jack was about to appear.

In other words, regardless of the urban legends in reality, at least here, these four omens indicate that Jack is about to appear.

Angel understood: "So, we need to find Jack's 'premonition'!"

X laughed. "What do you think we should do?"

"First, wander around! Find Jack's scarecrow! Then place the scarecrow in front of the factory!"

Angel thought she was extremely clever.

"Hmm, good idea."

Ex just smiled and looked at Elena.

"What do you think, Irene?"

"I think...we can 'create' Jack's 'trailer' ourselves!"
