Kei enters the boss's room and he sees that there were Mana crystals spread all over the room and it was used as the light source to light up the room. Other than that it looked like a pretty ordinary cave if it weren't for the fact that two gigantic monsters were fighting each other.
'Wait a minute, there are TWO BOSS MONSTER!!?' Kei screams inside his head. "HOW CAN THIS BE EVER POSSIBLE!!?" Kei thought that he would already have a bad time dealing with Serpent Maligora but now a grotesque-looking monster. It had a body of a golem but its face looked like acid had melted its face off and the rest of its body was rotting, but was not giving out any smell fortunately enough for Kei.
Kei carefully looks at the monster which was fighting the Serpent Maligora and remembered what it was 'It is Acidwrym, it only appears in B-ranked dungeons and above. What is it doing here? Even though the dungeon evolved it only evolved from one rank to another, not skip a rank. The monsters outside were only C-rank though. Even though the Elysian world is an open world, no monsters would invade a boss room to take it for themselves. How would I deal with it ?'
But then he dodged the acid that was spewed by Acidwrym which was intended to hit Maligora but it went underground. The acid melted the rocks of the cave and some of the rocks fell which were swept away by the Titanstoned Golems in the army. This had drawn the attention of the two boss monsters present there. After they looked at Kei and his army, they felt threatened so they screeched loudly and attacked together. Seeing this Kei immediately brought out the Mother of Dreadweavers and the army all attacked Acidwrym together while Kei alone attacked Serpent Maligora. There were a few reasons for Kei to choose this type of formation. Kei thought 'I alone can't handle Acidwrym so that is out of option. Distributing the army into two and attacking? I am pretty sure that both groups would require my assistance as half the original army alone can't handle the monsters. This only leaves me with one option I would send the army to Acidwrym and as they can't die they would give me enough time to kill or severely injure the serpent Maligora.'
The Mother of Dreadweavers and the Titanstoned Goles and Colsuss attacked the Acidwrym head on whereas small monsters like Dreadweavers, Luminari Weaveants and Eclispewolfs attacked from the side. Sometimes attacking its limbs and sometimes its eyes. Acidwrym became agitated and started to spew acid out which caused some of the monsters to melt away but to its surprise, they regenerated and attacked it again and this kept on repeating.
On the other side Kei was struggling, he couldn't manage to land a proper hit on Maligora. Despite its huge body, it was very agile and it mostly dodged Kei's attack or deflects it towards its iron tail where Yugen's imitation couldn't cut through. Kei also blocks most of its attacks. It was like they had reached a stalemate. Kei thinks to himself 'If only I hadn't damaged the real Yugen then it would have become much easier to deal with it.' Kei then thinks of something and to execute it he would need a little time but the problem was that there was nobody left to distract Maligora. His army was busy with Acidwrym and the group was gathered at the entrance of the dungeon.
Kei sighs and then he takes out his blade 'This is gonna cost me a lot Mana.' He creates a huge Mana imitation of the blade and slashes it at Maligora and it couldn't dodge it because it was too big. The attack left a huge cut in Maligora's body and it screeched loudly and before Kei could stop it, it went underground to recover by shedding its skin.
'This is a good opportunity for me.'
A few minutes later it reemerged but the look of the cave was completely different from when it left. It looked like the whole cave was painted black colour but it could still see Kei through his thermal vision who was feeding his army with Mana to continue their fight with Acidwrym.
Kei falls to the ground while coughing as he has already depleted his Mana and he shouts "Dammit".Maligora took the opportunity to attack as Kei had let his guard down. But what it didn't know was that it was a planned setup by Kei. The cave which was covered with Morphy instantly entrapped Maligora and Acidwrym in a tight hold.
Kei smiles as all was going according to his plan. Then he gets up from the ground while struggling. He had already depleted all his energy by killing the monsters outside of the boss room but the Mana in his body kept him going. Kei then quickly reabsorbs his army gaining back the Mana he had given to them. Kei quickly makes Morphy Yugen and turns the edge of it sharper and he takes a deep breath in. "Merciful Destruction" Kei instantly cuts Maligora's head into three halves.
'Thank god that I put much more Mana into Yugen to make a sharper edge otherwise I'm pretty sure it wouldn't have pierced through. This was a very sorry imitation of the Merciful Destruction though. I have to improve myself.'
Kei then divides the Essence of Maligora into 10 parts and starts to absorb but he didn't expect Acidwrym to break free of its hold and it attacked Kei while he was absorbing Kei and it smashed Kei into the ground, breaking most of his bones in his body and because he couldn't concentrate the Mana he absorbed went rampant in his body. 'I should've prepared countermeasures, Fuck!'
