The Essence of Illusion

The instant those claws crushed the frogs, a huge frog sitting cross-legged appeared above Mukuro Rokudo. It rapidly descended with crazy momentum. It was obvious that it was going to smash Mukuro Rokudo flat.

"This is how you use the illusion technique I teach you?"

Mukuro Rokudo pointed his trident to the huge frog, and it was torn apart. It was an illusion, so a good illusionist like Mukuro Rokudo could naturally nullify it. At this moment, the two sides fought each other with their illusion techniques and their mental fortitude. Fran at least believed that he wasn't weaker in terms of mental fortitude.

But illusion wasn't the only thing Demon Spade had. He could use all Dying Will Flames aside from Sky Flame and Earth Flame! That was what made him a scary opponent! Because of that, Fran had to be cautious in case Demon Spade launched a sneak attack while he was fighting against Mukuro Rokudo.

The only saving grace here was the fact that Demon Spade didn't have his ring, and without a ring, it was difficult for him to exert his true strength.

"Teach?" I simply do a boring illusion training that you ask me to do. Although that may be part of the reason I can get this far, I believe it's mostly because of my talent. To put it simply...I am a genius! I believe that Demon Spade-sama should be able to understand. After all, we are quite similar in this aspect."

It would be strange if people like Fran, Demon Spade, Mammon, or Mukuro Rokudo weren't geniuses.

However, Fran's tone sure ticked Demon Spade off. In addition, Fran was still joking even in this situation. Wasn't this basically saying that he was looking down on him?

"Ah, right, how about I give you a proposal?"

At this time, Fran suddenly took out a Den Den Mushi. Moreover, this Den Den Mushi had already been connected. He said, "I had already called boss' Den Den Mushi before I came here. Boss might've already called Primo-sama as well. If you waste too much time, Primo-sama may come anytime soon, and I'm pretty sure you don't want to get caught by Primo-sama in this situation, right?

Seeing the Den Den Mushi, Mukuro Rokudo's figure unexpectedly disappeared. It was clear that what Fran did shook Demon Spade, affecting his illusion technique as a result.

Mukuro Rokudo would never have thought that someone would use illusion techniques to summon him, and it was even more surprising for him to be defeated by a small Den Den Mushi. If Mukuro Rokudo could come to this world, he would've socked both Fran and Demon Spade for this.

"You really are..." Demon Spade became even more irritated. He thought they agreed on a one-on-one duel, but Fran notified others about it.

Fran: When did I say I would come alone?

When Demon Spade was distracted, a terrifying three meter-tall demon with wings on its back suddenly appeared behind him. The moment the demon appeared, bottomless darkness filled the world, enveloping him and Fran. As the darkness appeared, Fran's figure was concealed by the darkness.

Then, the emotionless voice echoed in the darkness, "Master taught me this. Illusion technique is used to control the opponent's five senses. And what an outstanding illusion master should do is actually take control of their opponent's five senses. It sounds very simple, but I was taught a lesson because I couldn't understand it so many times!"

The demon suddenly branded his claws and ruthlessly charged towards Demon Spade. The immense force tore apart the air in front of him, creating a sonic boom. The pressure was real, but it was different from Color of Supreme King Haki. It was like the arrival of a demon king from hell. However, Demon Spade just stood there with no intention to move at all.

The demon tore Demon Spade's back with his claw and sent him flying. Fresh blood gushed out from his back, but he still smiled.

"Your illusion is not weaker than your master's. It's just that when you fight against an illusionist of the same calibre in the future, you still need to think of your opponent's objective and then deal with it in addition to focusing on your illusion and protecting your five senses from being controlled. After all, the essence of illusion and deception are not much different. What your master said is not false, depriving your opponent of their five senses is ineed important, but deceiving an enemy is also a factor that an excellent illusionist should possess!"

Demon Spade scratched his head as he looked at the menacing demon, "just like how you used Den Den Mushi to contact Primo and the others when I wasn't paying attention, I have already achieved my goal just now. So if there is a chance next time, I hope you can stand with me and create the strongest Vongola, Fran!"

Demon Spade suddenly disappeared. Even the darkness that hindered his vision could not stop him from leaving.

It wasn't until the aura completely disappeared that Fran reappeared. He put away the darkness around him and scratched his frog head in confusion.

"He had achieved his goal? I don't know that he likes to joke around too sometimes. My ring is clearly still here..."

He placed his hand in front of his eyes and Hell Ring was indeed still in his hand. Otherwise, he wouldn't have been able to cast that demon illusion. But the moment he saw his hand, Fran's expression suddenly changed. He finally understood why Demon Spade would say that deception was also the quality of an excellent illusionist... 

"The Varia Ring is gone!"

A cry of alarm came from Fran, almost resounding through the sky. His Hell Ring was indeed still in his hand, but his Varia Ring was gone.

Demon Spade had already taken away his ring before he knew it.

How could he be an illusionist without his ring!

Suddenly, a deep and cold voice came from behind him and reached Fran's ears. "Oh? I seemed to have heard something I shouldn't have heard just now... Did you lose Varia Ring, Fran?"
