Advanced Fusion technique, otherwise known as the Soul Amalgamation is an ancient sealing technique where two users will be linked by their soul. It was now nothing but a lost method, only being mentioned in the books.
The Fusion skill card that is displayed by Azzy and 9-yr-old Flora was actually a watered-down version of Soul Fusion.
So, what is this technique that drew the curiosity from someone like Leah?
This special method will not just let them fuse the skill cards but also make the two users combine their attributes and soul skills, increasing their damage output by a whole realm.
And once mastered, even the Arcana of two users could temporarily merge; forming a new beast with both of their skill sets, and letting the two users share each of their soul power.
However, the Reaper was aware of the major drawbacks.
First of all, it is a temporary seal and can only work an hour at most. After that, it needs a whole other day to perform it again.
Second, even after the souls are linked, it only works in a limited distance. For example, Leah and Azzy activated the sealing technique but then, for some reason, they were separated.
With enough mastery, the range can be increased but during the beginning, they couldn't be separated even by ten meters if they want to enjoy the benefits.
And final, the biggest drawback is the transfer of injuries.
As the two users link their souls, one can transfer a part of their injuries to the partner without any consent of the latter. So, it needs an enormous amount of trust between each other.
When the Reaper first saw Leah and Excalibur, he already saw a distant future where both of them will battle to the death with clear hostility from the princess of Camelot and a certain degree of hostility from even Azzy.
More than a simple one of the possibilities, it appeared more like destiny because he could only see one. That's why he warned Azzy to be wary of her from the start. Naturally, back then, Azzy didn't understand the meaning.
If possible, the Reaper wanted Azzy to stay away from Leah but fate keep bringing them together, first through Champions League, then, the Draco-Galarian, now, the cosmic gem.
He doesn't have any idea what will lead them to that but the Reaper, who intended to alter the timeline while keeping the aftereffects to the world at minimum, suddenly thought that this might be an opportunity.
Who knows… Maybe, that battle from the far future can also be removed from the timeline?
Upon making his decision, he turned his head towards Leah.
Just as he was about to open his mouth, the latter spoke first, "I'm willing to give up the Jewel of Earth and instead, take the unique skills, if Azrael fulfills my conditions."
The Reaper as well as the Demigod Amerys was taken aback by her decision. It was, after all, the cosmic gem, a precious crystal that even make the gods go crazy.
Was she afraid of someone ambushing her over it? Was it because her father already possessed one and will probably pass on to her after his death? Or was it because her condition is worth the Jewel of Earth?
The Reaper didn't know what was going on in her mind but he was happier that not only they were on the same wavelength but Azzy was also going to get the cosmic gem. With two of them, there's nothing that can stop him to enter the God Realm.
"Speak your mind, child." The Reaper said to her.
Leah then asked, "Lord Tezca, can you make decisions on Azrael's behalf? I need your word for it."
"I already told Excalibur before and I will tell you once again. Tezca was my past avatar. Address me as Chronos." The Reaper reminded her and then nodded, "Yes, I will give you my word but only after hearing your condition."
Taking a deep breath with a serious look on her face, Leah put forth her condition, "I need Azrael to form a duo with me and participate in the world league. I want his best. It goes without saying regarding usage all of his three Arcana."
The Reaper stayed silent for a while. Since Azzy was already participating in the world league, he knew that the death scythe cannot be kept secret. With a few people already knowing about its existence, there's no need to hide it too.
Not to mention, this can also work in Azzy's favor. With three Arcana revealed to everyone, no one would suspect him about being the time traveler. Azzy only needed to keep the hourglass, a secret, at least until he makes a breakthrough to rank-7.
After thinking of all the possibilities, good and bad for Azzy, the Reaper made the decision, "alright, I will give my word but I hope it remains secret about the existence of the Jewel of Earth."
"Sure, you can trust me on that." Leah nodded with a smile. She further said, "Even if it somehow gets leaked, the Camelot will offer protection to Azrael."
"If you are finished with your conversation, shall I proceed with the next trial? We are pressed on time," Amerys interrupted him as if he was in hurry.
Both of them nodded.
"Okay, here we go…" Amerys snapped his fingers, creating a portal.
The both of them walked in together only to find Azzy's left hand and Leah's right hand were connected by an energy rope.
An instruction was heard from the sky. "I don't have the power to isolate Celestial grade Arcana from their masters. So, I can only ask the two of you to abide by the following rules.
One, neither of you will attempt to break the energy rope.
Two, neither of you will use soul skills or skill cards.
Three, neither of you can summon your Arcana. I will allow the possession but that's it.
If you break the rules, I'm afraid I will have to go back on all the rewards I promised until now.
Good luck."
Leah turned serious but abided by the rules and dismissed the Excalibur. The Reaper doesn't need to dismiss the death scythe for it isn't an Arcana but only a weapon of a Divine grade Arcana.
Still, he did it because the others believed that he is nothing but a spirit of the death scythe. Not to mention, it doesn't hinder his abilities in any way either.
A familiar-looking Sphinx was revived in the illusion realm.
"Girl, follow my lead." The Reaper first instructed her to move far away to test the length of the rope before they will attack the Sphinx from left and right.
Respecting the Reaper's status, Leah followed it and dashed towards the east while the Reaper did the same in the opposite direction. The Sphinx looked at left and right, wondering who to attack.
Within a few seconds, they felt the limit and looked at each other.
"So, it's roughly 50 meters, huh." The Reaper muttered under his breath, "more than enough."
He dashed forward while creating a bunch of Protos Spears. Leah also charged forward while conjuring a sword from her soul energy. The Reaper adjusted his speed to Leah's so that they move at the same time.
Analyzing the power between the Protos spears and the energy sword, the Sphinx made its decision and ran towards Azzy.
