Bell found a stone cave covered in ice. Bell also find some hard nut like fruits in a completely dried up tree inside the cave.
Bell took rest in the cave. He ate some of the dried nuts. He picked up some woods from the ground and prepared some fire to warm them up.
Aiz was fighting with Asterius. This time Asterius was stronger than Aiz, even with Aerial and avenger. They fought for half an hour. Finally Aiz run out of her wind magic. She was soon defeated by Asterius. But Asterius didn't kill her.
Asterius " You have got a long way to go."
Aiz couldn't say anything. she was surprised to hear him talk. Soon she lost her consiousness. Asterius left her all along.
Bell decided to go and search for his friends. On his way he defeated many monsters with the advice of Rocky. On his way he found Some monsters surrounding a fallen adventurer. Bell realized that she was Aiz. Bell without wasting a second fight and defeat all that monsters surrounding her.
Bell realized that she was unconscious. He picked her up gave her a picky back ride to the cave. He noticed that her was really cold and was seriously injured. She was really about to die.
Bell gave Aiz his last energy portion. He warm her body by setting up a fire camp next to her. He used the fur which he got as the drop item from those monsters to warm her up. Bell then asked Rocky to enter her body and heal her wounds. Then Rocky healed her completely. Bell then rubbed her hands and feet to regain some warmth.
Aiz slept for a day and a night. When she walk up Bell was sleeping next to the wall nearby. She felt pain and fatigue. She smiled in releif when she saw him. She felt really hungry as well. She decided to take some sleep for some more time.
Ottar and others joined up with Lefiya and Ryu. Thankfully no body died. They decided to move forward with the expedition( to reach floor 71) On their way they encounter many strong monsters. Ottar was the one killing most of them. While the others struggled to get along.
Bell and Aiz were already on the 71 st floor. But they have no idea. Bell introduced Rocky to Aiz. Bell asked about the opponent she fought. Aiz didn't tell Bell the real details. Aiz then explained herself why she rejected Bell. She reveals herself to Bell. She wanted to take revenge on the OEBD and save her mother. Bell promised her that he won't talk about it to anyone. Bell was shocked to hear her story. Bell then promised her to help her acheive her goal without expecting anything in return. Aiz was happy to hear that. They then started their move after taking enough rest.
Ottar and others reached at the opening of the 71st floor of the dungeon. It was freezing cold for all of them. They were welcomed by the floor boss. It was a 5 headed Hyrdra. It breathes fire, ice, lighting, Ultrasonic sound wave and other one breathes poisonous gas. They faced the doom itself. They were left with no other option but to fight.
Bell and Aiz met Asterius on their way. Bell asked Aiz to let him handle the fight.
Asterius wanted the same as well. Aiz decided to let him go, but made up her mind to step in if things go unfavorable for Bell. Bell and Asterius began their fated battle. Aiz was forced to fight other monsters that arised due to the arrival of the floor boss.
Ottar fought the fire-head, Allen fought the ice-head, Hedin fought the Lighting- head, Hogni fought the sound-head, Ryu, Lefiya and the Gulliver brothers fought the poison head. The hydra also attacked them with their strong tail. They were having a hard time. They were going all out. Ottar had to unleash his beast form to destroy it's fire head. Ryu used her unbreakable luminous wind magic sword to defeat the poison head. Hedin and Ottar together defeat the lightning head. Hogni pinned the sound head to the ground with the help of Gulliver brothers. Allen and Lefiya lend the final blow. Multiple magics in one go along with piercing spear shot of Allen destroyed it's magic stone. Finally they completed the expedition and all of them passed out of mind down and fatigue.
Rocky helped Aiz to defeat all the incoming monsters. After that they watched the battle between the two rivals. They were out of words to describe the battle. Aiz have never fought Bell like that. Aiz confirmed that Bell have already surpassed her.
Bell and Asterius continued their battle. They exchanged deadly blows. This time both of them were equally strong. Both of them were smiled as they battle to the death. Both of them go all out. They swing their blades with Amazing speed and strength. They counder attacked each other's attacks. They exchanged their will through their fight.
They fought for 45 minutes. Both of them are equally down. Asterius dropped his axe and decided to charge at Bell with his horns as a final blow. Bell already charged Argonaut for 4 minutes through concurrent chanting which he learnt from Ryu and Riveria. They charged towards each other. The sword and the horn clashed. Both of them roared. A bright light emerged out of the sword which may pierced through the eye. Both the sword and the horns broke with a loud sound and both of them were thrown backwards. Bell didn't stop. He launched forward as soon as his feet touches the ground with the black knife charged with 1 sec argo Vesta. Asterius try to catch him with his hands but Bell was fast. Bell cut open Asterius' neck with his black knife in the mid Air.
Finally the battle have come to an end. Bell won the fated battle. Asterius had a satisfying smile on his face before he turn to ashes. Aiz saw her own father in place of Bell. She was happy and proud at the same time. She wiped off the tears that came out her eyes.
