In the huge throne room, chaos ensued.
Near the door, two girls were constantly firing spells onto the incoming monsters while also putting enhancements on their teammates.
In the middle of the monster hoard, two boys were killing left and right, while also making sure that the monsters do not get close to their 2 teammates, but the incoming of monsters never stopped.
The killed monsters' blood spread out everywhere, the red carpet on the floor was now a darker shade of red, making squishy sounds whenever one stepped on it. The clothes of all four were torn and bloodied.
The girls had sweat on their foreheads, indicating that they are struggling at doing so many tasks at once, while the boys' stamina also seems to have taken a hit, as their breathing starts to become irregular.
Although, the strength of monsters attacking them has been gradually decreasing.
The first few monsters, they had to kill individually, by separating them from the group, but now they can kill many with a single attack.
This had been going on for quite a while. They felt guilty of leaving the boss to their fifth teammate alone, but if they can't even hold out with these monsters, how could they fight the boss?
That's when they heard . . .
"Listen you four. I think I found how this boss works, just kill every skelly you see"
They all turn their heads to see a bloodied, black-haired boy, who had tattoos all over his body.
But then they noticed, his whole left arm was missing.
Before they could ask anything, he put his remaining arm to the ground and said in a low and coarse voice . . .
"Cleave: Spiderweb"

A little while ago
Sukuna backed off from the boss and observed that he could no longer put Cursed Energy into the, now half, knife.
He looked at the skeleton to see it standing up with a big longsword in its hand. He knew that this monster was going to be big trouble. A Necromancer good at hand-to-hand? That's too overpowered, well like he's one to complain.
Meanwhile, the undead was also wary of him, it felt a big threat from that knife, so it had to put a lot of mana into his sword to reinforce it and cut the knife down, but as a result, the sword got bent and cracked.
Sukuna threw the broken knife at it, while it threw the bent sword at the knife. Both the weapons met in the air, creating a loud sound. By the time the weapons clashed, the skeleton was already far away. It started firing spells at him.
He started running towards it in an unpredictable motion, so as to not be an easy target for spells. Though, this did not work, due to his low physical abilities, his running speed was pretty slow.
The skeleton pointed its finger at him, firing a line of flames akin to a laser straight at his heart. Sukuna dodged and ended up with only a little burn to his arm, which was quickly healed.
The skeleton kept firing all kinds of spells at him, multiple kinds of fire spells, ice spells, and even earth spells, single-target, or area-of-effect, most of which did minimal damage to him, but he was getting a little annoyed by them.
The skeleton was sure to keep a distance from him, it had already deducted that he was strong at hand-to-hand.
Sukuna swiped his hand vertically, the slash he sent cut the humerus of the left arm of the skeleton into two.
'Isn't this . . . too easy?'
The slashed bone glowed with a faint light and its arm healed almost instantly.
'Shouldn't have said that.'
Sukuna kept sending slashes into many parts of the skeleton's body while also trying to get closer to it and pull it into close-quarters. At some point in the fight, the skeleton had stopped running away and instead, started to fire stronger spells more frequently than before. He noticed that the closer he got to the skeleton, the more frequently the attacks came.
He fell back to think about his observations.
'The farther away its target, the less frequently it fires spells.'
'So I assume it's harder to cast its spells at a distance, so it takes it longer to make them have the same intensity as the ones closer to it'
'My running speed is really slow, leaving much room for it to attack, so the only option is that . . .'
'I need to do a ranged attack, maybe . . . that?'

"Open"
Fire started forming on Sukuna's hands, creating a bright light in front of his face, due to which a huge shadow was formed behind him on the wall, developing an intimidating image in front of the skeleton.
The skeleton immediately started gathering mana in front of it to use it as a barrier. It was quite good at adapting to its opponent, it had already figured out that large amounts of mana can disrupt the spells of the human against it.
Meanwhile, the fire in Sukuna's hand started contracting and formed an arrow as he pulled his hand back. This picture could send chills down anyone's spine if they were fortunate, or unfortunate, enough to witness it.
The arrow was released, time seemed to slow down, as the arrow shot close to the skeleton, the gathered mana could do nothing to stop it in its path. he arrow was right at aim, hitting the sternum of the skeleton, Burning most of the bones straight to ashes, while a few remained cracked and burnt.
'This was fun,' thought Sukuna as he turned away from the 'body' of the skeleton.
.

Loud clicking noises started coming from the ashes, Sukuna felt a large amount of mana gathering at the remaining bones of the boss, as it glowed in a bright light this time, healing it up from literally ashes.
'That amount of mana is too exaggerated, definitely not an amount a B-Rank or even a mid A-Rank can possess, which means that . . . it has an external source of mana'
'The bosses of dungeons are directly in connection with the dungeon core, they can draw mana from it at will, but the speed of drawing mana is really slow, making its use negligible in battle.'
'It also cannot be taking in mana from the environment, as the density of mana inside its body is higher than in the environment by hundreds of times, circulating mana into its body is too inefficient to be used in battle.'
'Where could it be getting that amount of mana from? Think
