Start in Terra, immortal

Walking along the avenues of Central Park, surrounded by plants and trees that seemed out of place in the rest of the Demon Realm, Casillas felt a sense of unease.

"How could a powerful expert be staying in a place that shows no signs of cultivation? Hilder wouldn't be lying to me, would he?"

Casillas muttered to himself. Suddenly, a powerful aura of battle appeared in Casillas's senses.

"That must be where the summoner is!" Casillas suddenly became excited, his hand already unconsciously resting on his weapon.

As he approached, just as he was about to introduce himself, the woman among the two spoke first: "Respected Casillas, may I ask what brings you to my residence?"

"You... you knew I would come?"

"The elves around here told me that the Fourth Apostle, Casillas, will be visiting this place." After saying this, Salmon glanced at Rosso.

"So you must be the Summoner Samon. I'll be frank, I've come to you to become stronger. Hilder said you could let me fight against truly powerful opponents. Although she said those I've encountered before might not have been truly strong, the First Apostle, Cain, whom you speak of, easily defeated me; he's definitely a true powerhouse. I, Casillas, live for battle. I'm not qualified to fight him now, so I need more battles to become stronger. Therefore, please do me a favor and let me fight against more powerful opponents until the day I'm qualified to face Cain."

"But I am only responsible for communicating with all living beings in this world so that they can help and understand each other. I cannot force them to fight you..." Salmon seemed very troubled.

"On my way here, I inquired about you. I heard you possess a kind of contract magic, capable of forming contracts with other life forms and summoning them to fight when necessary. If you sign a contract with me, giving me something to fight with, I'll do anything you ask!"

As Casillas spoke, he assumed a fighting stance and stared intently at Rosso.

"Just sign it if he tells you to. Free bodyguards. If you don't need them, you can give them to a demon who does. It's a great teaching material delivered to your door, so why not take advantage of it!" Rosso interrupted the two's struggle. Given the difference in their strength, the fact that they could still sign a contract made him even more interested in this magic.

Seeing Rosso speak, Samon simply didn't refuse anymore, and even Casillas's grimaces showed a rare smile.

After setting up the magic circle, he strode into it, and a dazzling light rose up.

"The contract is settled."

Immediately after the signing was completed, Casillas approached Rosso and said impatiently, "From what I've observed, your battle aura is exactly what a strong person should possess! I request that you step forward and fight me!"

Upon hearing this, Rosso seemed to have thought of something as well, and grinned, "That depends on whether you can find a spacious place. After all, this is not a good place to fight." With that, he walked straight out.

Upon receiving a response to his challenge, Casillas appeared quite excited. "Excellent! You truly possess the demeanor of a strongman! Let's find a spacious..."

The sound stopped abruptly, and the wide smile suddenly froze.

"My body... I can't move? This feeling, this familiar feeling—it's you! It was you all along! Kahn didn't lie to me, it wasn't him that day, it was you!" Casillas's ferocious face was distorted beyond recognition, and the trembling of his body was far greater than the day he was forcibly trapped in place after just ascending to the Demon Realm.

"So, this is the real strongman Hilder was talking about. She's right. I really haven't seen any strongmen before. Haha, haha..." Confusion began to appear on Casillas's face, just like the day he was easily defeated by Kahn.

The difference is that that day it was just a setback, while today it's a feeling of powerlessness that arises spontaneously.

"You may not know, but before I met Kahn, I considered myself no less than anyone else; after meeting Kahn and being defeated by him, I regarded Kahn as a goal, an insurmountable yet approachable mountain; but today, that person did what even Kahn couldn't do—prevented me from drawing my sword. Perhaps he is also an insurmountable mountain for Kahn? Even if I can reach Kahn's level through constant battles and growth, what does that amount to compared to him? I don't know, I really don't know!"

Casillas murmured, as if speaking to Salmon, or perhaps to himself.

Samon had no intention of gloating over the defeated apostle. Although he had long suspected the apostle might be powerful, he hadn't expected him to be this strong. Even the elemental spirits hadn't escaped the 'imprisonment' just now. According to the spirits, they felt pressure from all sides; the elements that were supposed to be one with them suddenly turned against them, countless elements fixing themselves around them, trapping them and rendering them immobile.

Seeing the still dejected Casillas, Salmon comforted him, "Lord Casillas, there's no need to doubt yourself. Lord Rosso's realm is beyond human reach. Perhaps Lord Rosso's power seems unattainable to you now, but what will you think when you finally climb over Lord Kahn's mountain as you wish?"

'Perhaps even more untouchable,' Samon added to his mind. Sometimes, the more you know, the more you realize your own insignificance. This skilled and warlike fighter whom he had already signed should not lose his drive and ambition.

Being an Aiken, his mind was preoccupied with combat. Consequently, other mental tasks didn't linger in Casillas's thoughts for long. Giving up the fight he relied on for survival was out of the question. He didn't care about Kahn or Rosso, or whether he could overcome mountains; he could simply avoid challenging monsters like them in the future. All he knew was: fighting! It was exhilarating!

After leaving Central Park, Rosso returned to the spirit world, drew a magic circle as Samon had demonstrated, and casually summoned a little white rabbit and threw it in.

After the light faded, Rosso felt he could directly understand the rabbit's thoughts and forcibly transfer it through the engraved magic circle.

It could even sense that Casillas had already signed a contract with Samon. With a thought, as the magic circle was set up, the space of the spirit realm rippled for a moment and then fell silent.

"I can sense that summoning doesn't require breaking through space. After all, Casillas's body can't be quantified, and summoning him as a spirit requires his consent. It seems that cross-dimensional summoning needs some improvement." Rosso didn't consider Casillas, who was eager to try it out outside, and continued his research.

Central Park, next to Salmon's flower field.

"Your summoning technique doesn't seem to be working properly. I sense someone calling to me, but I can't get there! Did you teach me this?"

Feeling resentful for missing out on a battle, Casillas questioned Salmon.

"Of all the summoners I know, only Lord Rosso has the ability to summon you!"

Samon smiled and teased Casillas.

"What utter nonsense? Huh? Ah! That must be my fault. Next time there's a summoning, I'll tear through space to get there, and I guarantee the summoning will be successful!"
