After passing through the portal, they found themselves in front of the entrance to the top floor and the boss room. She pushed the doors, getting ready to begin the long awaited final battle, and Allen told her that this door was just for show. This floor used a portal teleportation system, like the middle one. But there was no portal anywhere, which meant someone was already inside.
Melissa worriedly asked if another group was already fighting the boss. He confirmed this, and she touched her chin in confusion. She knew things were bad. If they beat the boss first, she and Allen would have to start all over again.
He crouched down and said that worrying wouldn't change anything. They could strategize while they waited.
The boss of this zone, the crystal dragon, used an instant death attack.
Melissa was very surprised. She hadn't even known that.
Allen reminded her that their opponent was an epic class, so it was very possible. The girl was surprised, because an epic class was an even higher rank than a boss. Not only did they have much higher stats than a boss, but they also had different unique features, depending on the enemy.
Allen told her about the crystal dragon's unique features: an instant death attack, and a damage limit. The latter meant that there was a strict limit on the damage that could be dealt. No matter how powerful the attack, any damage exceeding the limit was completely negated, she clarified. So its overwhelming firepower was useless here.
He confirmed it. Besides, the dragon had an instant death attack, so he wanted to determine their battle strategy in advance. There were endless waves of small enemies in the boss room. They would keep appearing until the boss was killed. So he needed her to destroy those mobs, and he would deal with the boss.
She agreed, but clarified what he would do during the instant death attack, to which he replied that he would somehow handle it. When he gave the signal, let her hide behind him.
She told him that she understood everything, and finally a portal appeared at the door. Since they had not been teleported outside the castle, it meant that the previous group's battle was over. They had been destroyed.
Allen said that once you teleported to this zone, there was no escape.
And Melissa said nervously, just think — even experienced adventurers who were able to reach the boss couldn't defeat him. She wondered if they had been killed by the instant death attack, or by something else. She was already starting to get nervous.
He told her that everything would be fine. If they stuck to the strategy, they would definitely win.
She smiled slightly nervously and asked if they could really do it. To give her confidence, he told her to rely on him until he became the world's first level 999. He couldn't afford to die.
They entered the boss area, which was a large coliseum. A pile of dead adventurers lay in the arena. Melissa kept looking back at them, and Allen said that they had no time to be afraid. The boss was already here.
A crystal dragon descended from the sky, flapped its wings, hovered above them, and then screamed loudly. Now Melissa finally saw with her own eyes what an epic class really was.
Allen told her not to give in to the pressure. This wasn't the only enemy here. They were surrounded by a huge crowd of monsters.
He took out a machine gun and reminded the girl that all the mobs were hers, then opened fire on the monster, dealing heavy damage one burst after another. The machine gun's rate of fire was the perfect countermeasure against the damage limit, so it wasn't a problem.
Melissa was delighted. She was delighted with how he was suppressing the boss, and he said that the crystal dragon was a problematic opponent, but as long as they knew its mechanics, there was nothing to fear. They would press it with their advantage.
Melissa continued attacking, but at one point Allen ran out of ammo, and the dragon took advantage of this to attack. It raised its head, and Allen immediately recognized the move. It was the instant death attack.
He warned the girl about it, and she immediately retreated and hid behind him. The dragon gathered the black flames of death in its mouth, and then aimed them at them, and the girl worriedly called out to Allen.
He used the creation skill, and a wall grew from the ground.
Melissa didn't understand what it was, and Allen told her it was a fireproof shield. The instant death attack was dangerous, but if you didn't come into direct contact with it, there would be no problems. Now she understood why he had made it a freestanding shield.
He said the machine gun had already reloaded. As soon as the boss's attack ended, they would launch a counterattack.
Suddenly, the shield cracked, and Allen noted that things were bad. That wasn't in the plan. He had thought the fireproof shield could block it, but its strength wasn't enough. With a new gust of flame, new cracks appeared on the shield. Any more and it would break.
Allen wondered what he should do now. There was no guarantee that another fireproof shield would hold. He needed another way.
One of the shield's layers cracked, and Melissa called out to Allen in fear, making him nervous. He couldn't afford to die in a place like this.
He quickly came up with a way out of the situation and created a fire extinguisher with a slot for a magic stone. That was the first thing that came to mind when he thought about what he could put the fire out with. To maximize its power, he fused it with the strongest material he had, the crystal ogre magic stone.
But would it really work? He ran out of cover. There was only one way to find out. He bet everything on his ability, turned to the flames, and doused them with the fire extinguisher.
Luckily, it worked.
Melissa was surprised. This thing had collided directly with the dragon's breath. The dragon continued to breathe flames, and Allen screamed, not knowing how this confrontation would end.
Eventually, the fire extinguisher put out the dragon's powerful flames, and the deadly attack finally ended, leaving the girl in shock.
He told her that a fire extinguisher was not a weapon. As the name suggested, it was a tool for extinguishing fire.
He took out a machine gun, and since the crisis had been averted, it was time to counterattack. He opened fire, and the dragon's health began to gradually decrease, and Melissa was delighted.
The dragon fell from the heavy damage. Allen told Melissa to act. Let her ignore the small things. They would finish him off together.
She joined the attack, and together they quickly reduced the enemy's health bar to half, not even giving him a chance to strike back.
And finally, the dragon was defeated. His body turned into many small crystals and scattered across the arena, and their levels increased.
Melissa asked whether he hadn't panicked a little back there. He told her that it didn't matter, since they had won. He took the dragon's magic stone, and she asked what about the jade dragon orb.
He pointed to a chest not far from them and said that it was in there. After defeating the boss, a treasure chest appeared. She could check it out for herself.
