"Actually you can't feed these weapons to Beelzebub's sword since it's smaller than these two" Sefra said.
"Why does that matter?" Jean asked as he stood up.
"These weapons can only swallow their size or smaller but you change the form into one of the weapons it swallows. Look for the belly of the club" Sefra explained.
"Alright… the belly?" Jean asked.
"It's near the head of the club" Sefra said.
Jean hovered Satan's sword over Belphegor's club and after he waited half a second, a small hole opened up and seemed like a purple mouth. The walls covered with 8 layers of sharp rotating teeth. It was similar to how Belphegor's teeth look but this was creepier.
Jean slowly dropped Satan's sword into the purple mouth. As Satan's sword left left his hands and the hilt of the sword fell past the mouth, the mouth closed and the club's design changed.
The original design was simple. It was just an abnormally large pitch black club covered spikes. The handle was covered with a torn off piece of tattered human skin, surprisingly still hanging after thousands of years. After the sword was swallowed, the color was more of a beautiful shiny blood red steel with less spikes that were more rugged, the club itself grew larger and thick.
Jean held his sword over the belly of the club and it opened but the mouth's color wasn't only purple, it gained a red hue to it, after swallowing Satan's sword. He again pushed the sword into the club, and once the hilt fell past Jean's hand and into the club's mouth. After the sword was devoured the club changed again. The tattered piece of human skin stretched around the hilt, the club grew a bit slim and the spikes became more refined as the color seemed more polished. Soon after the handle slowly started injecting itself into Jean's hand, crawling from his right arm to his left arm wrapping around his muscles. The three sacred treasure of hell's 7th, 6th, and 5th floors were now bonded with Jean.
"These relics are more like the hearts of these floors, aren't they?" Jean asked as he inspected his arms.
"Why you say that?" Sefra asked.
"That's how it feels but I fed it….how do I change it to the other sacred treasure" Jean said before the club changed into Sloth's sacred treasure.
"I'll take all of your fatigue as soon as these floors are devoured and you can head to the next floor" Sefra said.
"What about you, where will you go?" Jean asked.
"I'm gonna rest in your shadow for a while" Sefra said.
"Alright" Jean said Sefra picked him up.
As soon as Sefra picked him up, the two floors above him disappeared just before the floor he was standing also disappeared and the pillars of his shadow turned to 3 small balls that flew towards him, each going into his stomach and spreading throughout his body reaching from the middle of his stomach to the tip of his toes, fingers, and head. The feeling of his mana/ body getting stronger and more dense, it was similar to a feeling of relief spreading throughout his body. Jean immediately knew he finally devoured all three floors as his eyelids felt heavy and quickly started lowering themselves as he laid on Sefra's back. But suddenly that feeling of tiredness quickly drifted away as he felt the solidity of his familiar's back disappeared, he opened his eyes and noticed how light and strong his body felt but he also noticed that he was no longer on Sefra's back, instead he was falling approximately 2000 kilometers from hell's sky.
As Jean was falling, three tentacle looking figures came flying towards him and started wrapping around his limbs.
"What the fu-" before Jean could finish his sentence the tentacles pulled him downwards.
As the tentacles pulled him downwards, needles pierced his limbs and his weapon slipped out of his hand. As he was being pulled, the speed kept increasing, and his weapon was trying to catch up to him. Only a second and a half passed before Jean was slammed on the ground, his weapon which was rushing towards him, finally caught as it seemed like it was gonna stab him it stopped and lightly placed itself near Jean's arm.
"I think he's dead, daddy" Demon1 said as he inspected Jean's body.
The strings unwrapped from Jean's limbs and pulled back to a chair, that was sitting on top of a podium, Leviathan sitting on the chair with his sacred treasure laying next to him. His sacred weapon was a large sledgehammer that was about 10ft long, the head of the sledgehammer was bulky, nearly 3 feet long, and 5 feet wide.
"If that was enough to kill him, there wouldn't be four Demon kings left" Leviathan said.
"Isn't this master Belphegor's katana, daddy?" Demon2 said as he tried to grab Jean's weapon.
"Not only Belphegor's sword but, Satan's Two handed sword, and Beezlebub's club" Leviathan said.
In one action Jean stood up and jumped back but he felt his back hit something and when he looked behind him, there was another demon to which he jumped away from before his sword flew into his hand, while rubbing his eyes.
"They've bonded to you, a human?" Leviathan asked.
"Son of a bitch" Jean said as he stopped rubbing his eyes.
After Jean stopped rubbing his eyes, blood started pouring out from them, and his vision became blurry although he was still able to make out the some movement, he wasn't able to accurately assess them.
"You look like a king sitting there, are you sure that's the right spot for you?" Jean asked as he lifted his head.
"You were able to see me?" Leviathan asked as he looked at his arms.
"I only caught a glimpse before the poison activated" Jean said as he tried looking around.
Leviathan grabbed his weapon and darted towards Jean. When he was standing in front of Jean, Leviathan tried to attack him but when his hammer was just above his head, he was able to make out a blurry image of it, before he was barely able to dodge it as the hammer smoothly swept his arm off his shoulder. One of the demons tried rushing Jean but Leviathan lowered his sword in front of him.
"Dark Impulse, Step Four: Envy" Jean said.
As soon as Jean activated this step, his vision was clear as the blood stopped spilling from his eyes, and his arm healed. Then Jean wiped the blood from his face.
His shadow changed into 300 fairly small spaced out tentacles and half of them wrapped around his arms and legs.
"You've stacked up so many sins, your practically a prince, just below the kings" Leviathan said as he raised his arms.
"What the hell?" Jean said in confusion as he looked at his shadow.
Leviathan used Jean being distracted against him and decided to attack him. He darted towards Jean again and once he was in front of him he tried thrusting his hammer into the side of his head although Jean noticed him, he wasn't able to dodge his attack instead he used his sword to block Leviathan's attack. And upon impact the attack sent Jean flying into a crowd of demons.
As he crashed into the floor, all of the demons backed away, and allowed him to get up although Leviathan was already in front of him without giving him a chance to stand, he attacked him but Jean used his shadow to push himself away from Leviathan's attack, the only thing that was cut was Jean's shadow which grew back instantly.
"Damn it" Jean said as he looked at the shadows again.
Leviathan rushed him again but this time Jean centered his focus on him instead of his shadows and rushed towards as well. When they were close enough to each other. Leviathan attacked first although Jean jumped above him, he stopped his attack and moved away from that spot he was in so Jean wasn't able to land an attack on him. Leviathan, however, could and waited for the tip of Jean's feet to land on the ground before he immediately swung his hammer. Leviathan was able to land a clean hit on Jean's lower body that would've ripped right through him if he didn't jump away.
Jean's body quickly regenerated before Leviathan rushed him again. Leviathan kept throwing a barrage of attacks and Jean barely dodging that or deflecting them to throw his own which weren't effective as Leviathan would always block them. But they were both growing tired of this ritual as Leviathan threw another attack, Jean descended with it making it seem like he was hit by his attack and when he got close to the ground, he used his shadow to push himself towards Leviathan, aiming for his legs but when his hammer made impact with the ground it sent a gust of wind flying in all directions almost like he knew it was gonna happen, he quickly jumped Jean, lifted his hammer, and slammed it on Jean's head. Turning his head into small chunks of meat.
"Can I take his soul, daddy?" Demon3 asked as she walked to his side.
"…" Leviathan ignored her and stared at Jean's body.
Jean's body stood up and jumped back, holding his sword up in the direction he can sense him coming which was off by 8 meters.
"Hey, daddy, what is that?" Demon1 said.
"…I don't know" Leviathan said as he watched Jean's head regenerate.
"It isn't working" Jean thought to himself.
"He's weaker than I thought, how did those three lose to him? That body is practically wasted on his soul" Leviathan said before he rushed Jean.
"Fuck it, I'll just have to do with out it" Jean thought before he noticed Leviathan zooming towards him.
Once Leviathan was close enough, Jean disappeared and tried to cut his head off but Leviathan disappeared just before Jean's blade reached his neck and landed a kick on his chin with the heel of his foot, causing Jean's chin to be wiped off of his face as if it was a stain.
Jean disappeared again, when he reappeared his chin was already regenerated and he was going for another attack. As Leviathan tried block it, Jean pivoted his body to the right side of Leviathan's body and aimed for his arms. Leviathan immediately noticed his target but Jean's speed slightly increased as Leviathan was able to stop changed his hammer's direction. And as soon as Jean cut his right arm off, Leviathan's hammer slammed on his head.
They both ended up jumping back to heal/regenerate their bodies. When Jean's head was regenerated, he felt dizzy as Leviathan was ready to go back into fighting and appeared right behind Jean with his right arm nearly healed, he pulled his hammer down Jean with only his left arm but Jean lowered one side of his body to following the hammer's direction, in one quick and smooth action his body flipped and he was able to land a kick on Leviathan's temple which also sent him flying a couple feet.
"An increase in your strength? What are you finally taking this serious or something?" Leviathan said as he quickly stood up.
"I've been taking you seriously this whole time, I'm just using my physical strength along with my failing step" Jean said.
