Ben quickly broke the walls and reached the location where he felt Mira's magic power. He arrived in a spacious room with big cylindrical glass tanks. Ben looked around and saw 10 Etherious there who are looking at a broken glass tank.
Ben smirked and said, "It seems I had nothing to worry about."
"Hmm. It seems you've lost a lot of weight, haven't you darling?" Mira asked, still in her basic Satan Soul form.
"And you seemed to have changed a little, love." Ben said after sensing Mira's magic power.
"He he, these guys actually helped me become stronger by ejecting demon particles into my body. They tried to turn me into a demon, but it helped me become a lot stronger instead." Mira said.
Ben's relieved expression became a hostile one after he heard that. "Turning my wife into a demon? You guys sure have a lot of guts."
Very strong pressure fell upon the room and every demon there fell to the floor. Ben knew these demons because he gathered Intel on Tartaros. The 6 were members of the Nine Demon Gates, a elite group within Tartaros while the other 4 were their subordinates.
"The one I killed is Ezel, then the one fighting Erza and Kenshin right now is Kyoka, the one near Natsu and Lisanna is Silver. I never thought that the first Devil Slayer I would encounter is part of a guild of demons, but whatever. As for you, you're Seliah, Jackal, Keyes, Torafuzar and Franmalth, right? You look different, but your power is around the same level as those 5. So you must be Tempester, right?" Ben asked with a threatening tone.
"Also, I never expected you would become a demon, Jiemma. As for your daughter, I don't know if you took her with you or she joined on her terms. This is still surprising, though. Do you think you can become strong enough to defeat me by doing this? You seriously underestimate me." Ben said as he increased the pressure.
The pressure he released wasn't pressure from gravity, but the strange pressure he released during the Grand Magic Games. It came from Ben's immense magic power and the majestic presence that he awakened through his Sun Devil/Dragon/God Slayer Magic.
Even Ben had no idea how he had access to this ability. He speculated it was inherited from Midas the Sun Demon, Escanor the Sun Dragon, the unknown Sun God or even the 3 of them combined. At the very least, he knew that Midas and Escanor were the strongest of their species, so this is possible.
This pressure would only work on those with much lower magic power and mentality. And with Ben's immense magic power, there weren't a lot of people who wouldn't be affected by this. So far, the only ones Ben knew about were Zeref, the dragons and possibly God Serena.
"Where's your boss, demons? Where's Mard Geer?" Ben asked, walking forward.
The Etherious were silent even though their bodies trembled. These guys were extremely terrified of Ben right now even though they were very haughty and looked down on humans. Even so, they won't tell Ben anything about Mard Geer.
"Well, you don't actually have to tell me anything. I've sensed his power since my arrival. I just wanted to give you a chance to talk for the final time, so let's end this here." Ben said while covering his thin arms with dark red solar energy.
"Wait, Ben! Let me take care of one of them. She was the one that planned the whole kidnapping and maybe everything else. Also, she seems to have done something to Elfman, so I need to handle her personally." Mira said while looking at Seliah.
"Anything you wish, love." Ben said as he released the pressure on Seliah.
Mira immediately flew forward and grabbed Seliah before moving to another area of the cube. So now, Ben faced 5 of the Nine Demon Gates, the demonic Jiemma and Minerva, and 2 demon subordinates. He released all of them from the pressure and told Bella to tightly hold onto his head.
"Come, demons! I'll give you one final chance to save your lives." Ben said while taunting them with his thin left hand.
"One final chance? You're as arrogant as we heard. Don't you know that we deliberately waited for you because we knew you would come here. Obviously, we came here prepared to face you, true Dragon Slayer." Keyes, the one resembling a skeleton said.
A circle of magic letters with a pentagon formation inside it suddenly appeared on the floor. Ben was inside the formation and he just looks at them. Then he suddenly teleported Bella away and sent her to Carla's location because this will be too dangerous for her.
The formation was activated and now Ben is trapped in a circle of pentagon magic walls. Dark particles start to fill the inside of the formation and the demons are smirking. Ben was still looking at them calmly as if nothing is wrong.
"You could've used your magic to leave that spot, but you chose to only send the cat away. It's just like we heard, you are very arrogant and think highly of your power." Keyes said again.
"Arrogance? Hardly. That is pride. I am a very prideful person who believes in my own power. I need to have this attitude as the successor of the Sun Dragon Escanor's and the Sun Demon Midas' power. This is a attitude befitting a real king." Ben said, holding his head high.
Jackal smirked and said, "Then die with that pride of yours. It's the first time we've heard that you're a Devil Slayer, but it doesn't matter. You will die anyway."
"Die? Me? Just because of this? Heh, it seems the ones that are arrogant are you guys, not me." Ben said as his eyes glow dark red.
Suddenly, a dark red flame fills the entire room where Ben is 'trapped'. All of the dark particles were burned to nothing, including the ones that entered his body when he breathed. These dark particles are very dangerous, but they can't withstand the power of Ben's magic.
"What the hell?! He can still use that level of power even when a lot of Magical Barrier Particles entered his body?" Tempester asked, surprised.
"Don't panic! This is something that we anticipated when facing someone like him. Let's continue our attack." Torafuzar said while crouching and putting his palms on the floor.
Suddenly, black water came out of the magical formation that trapped Ben. It came out of the walls and turned the inside black. The demons looked at it intensely while still keeping their guard up.
"Poisonous water, a rather interesting and sinister Curse. Well, all your Curses are sinister, but they are worthless if they are weak." Ben said from inside the black water.
The demons saw the black water boil and evaporate because of the super hot solar energy generated by Ben's Sun Devil Slayer Magic.
"Carbon is very dangerous for living things even though everyone needs it. Well, maybe you already knew that because it's your power. But did you know that with enough pressure over a long period of time, carbon can become a very hard item?" Ben asked as if he was giving his students a fun fact.
"If you didn't know that, I'll show you." Ben said, before creating a small dark purple gravity ball right in front of him.
Suddenly, the dark water was pulled into the small gravity ball. Even the barrier walls were contracting and were pulled into it. Then after all the black vapor disappeared, the barrier walls start breaking down, freeing Ben from the 'trap'.
Ben kept the gravity ball, but it no longer affected the surrounding area. It only affected the dark vapor gathered around it. He increased the gravity pressure and after a while, a clear round ball appears.
"I thought it would fail, but I actually made a diamond out of carbon. Interesting, isn't it?" Ben asked the demons who weren't interested at all.
These demons aren't stupid, they knew Ben could have escaped from the very beginning. He was just playing around with them. They finally know what kind of monster they were up against right now.
