Inside the mine, all the monsters still alive began to tremble.
Those who were close were suppressed by the substantive pressure, unable to move.
As for those who were slightly farther away, they trembled when they sensed the erupting dragon aura.
Not only did the Professionals guarding the entrances of the low-level and high-level mining areas feel this, but even the adventurers who had already walked out of the mine and were preparing to go home felt this suffocating pressure.
Looking at the fiery red sky, the security guards guarding the entrance of the mine were all shocked. "What the hell is happening?!"
Seeing the few trembling summoned creatures beside him, a Summoner could only helplessly put them into his contract space. "Behave yourself!"
Even though they were in the contract space, the Professional, who had already walked out of the mine, could still feel the fear in the hearts of his pets.
It was as if something extraordinary was happening in the mine that was about to close today.
Inside the mine, the Professionals who had just walked out of the safe mining area stopped in their tracks because of the strange phenomenon in the sky.
In the eyes of the Professionals, above the undulating mountains, the originally dark sky seemed to be filled with blood at this moment.
It gradually dyed the surrounding thick clouds red.
It was as if the apocalypse had arrived, giving everyone a great sense of fear.
"Hey, what the hell is happening?!"
"It looks like the sky is bleeding. It's too scary!"
"Could some powerful monster have broken through the blockade of Bo'an City's city wall and rushed here?!"
Looking at the disturbing scene in the sky, everyone was guessing what was going on.
How could they know that the person who caused the monsters to tremble and the phenomenon in the sky was actually a Level 5 novice Professional?
…
Inside a certain cave in the high-level mining area…
Looking at the constantly expanding Red Dragon King, Su Ce was very excited.
The stronger his pet was, the stronger his combat ability.
This feeling of being able to easily control a powerful dragon made his heart flutter, and he couldn't suppress his excitement.
Su Ce looked at the few high-level monsters trembling not far away and said in anticipation, "Do it, Red Dragon King. Let me see how powerful your forbidden spell is!"
Sensing her master's thoughts, the Red Dragon King didn't hesitate at all. She raised her head proudly and opened her bloody mouth.
Red flames were constantly emitting from inside!
Looking at the terrifying energy in the Red Dragon King's mouth, Su Ce grinned. Seems like this is a charging skill!
There were many prerequisites for casting a forbidden spell.
First of all, the caster of the forbidden spell had to be powerful enough.
Furthermore, it required extremely high MP and the ability to comprehend the forbidden spell.
Under normal circumstances, the caster would need to accumulate power for half an hour before casting the forbidden spell. If their MP wasn't enough, they would need the cooperation of other Mages to complete the entire process of casting the forbidden spell.
At the same time, the troublesome prerequisites also meant that forbidden spells were powerful.
Forbidden spells could insta-kill monsters around Level 80 in most cases.
Large-scale forbidden spells could even instantly turn a small city into ruins. It was precisely because forbidden spells were extremely destructive that they weren't easy to cast.
Most of the time, the casting of forbidden spells required the cooperation of several Mages.
And among all the Mages, those who could cast forbidden spells alone were even rarer.
Therefore, even a Level 100 Red Dragon King would need a few seconds to accumulate power to cast a forbidden spell!
Su Ce looked at the red flames accumulating in midair and felt the terrifying energy.
An aura of arrogance instantly reverberated throughout the mine.
The Professionals still in the underground mine seemed to sense something and hurriedly fled the area.
A few parties retreated in a hurry. Even the eight Professionals guarding the entrance of the low-level and high-level mining areas received the news and immediately evacuated.
After leaving the underground mine, numerous Professionals immediately discovered the amazing sight in the air.
Looking at the phenomenon that almost dyed half the sky red through the clouds, the Professionals all gasped.
"What's going on?!"
"Let's retreat first. I have a bad feeling!"
"Could some big shot have come to the mine?"
A few people discussed nervously and then tacitly left the mine.
…
Boom!
Inside the cave, the Red Dragon King, who had her head held high, had already finished accumulating power for the forbidden spell.
Standing on the ground, Su Ce saw a blood-red fireball rising to the top of the cave.
The flames were as bright as blood, looking like flames from hell!
Su Ce patted the Red Dragon King's skin, his expression full of excitement. "Do it. Let's see how powerful this move of yours is!"
In the next second, the Red Dragon King opened her mouth, and the fireball above her head instantly exploded.
The terrifying temperature instantly melted the cave.
The three high-level monsters standing not far away were quivering. They didn't even have time to scream before they were instantly vaporized by the terrifyingly high temperature.
But the power of the forbidden spell was far more than this.
The flames that could be called the flames of hell instantly filled the entire cave.
As Su Ce was standing beside the Red Dragon King, he wasn't affected.
But looking at the flames covering almost every corner of his vision, he could also feel the terrifying sense of despair.
In comparison, the hell eyeballs and frost-toothed bats that couldn't resist looked much more miserable.
Before they could react, they were already engulfed in flames.
The entire cave disappeared in an instant. The hard rocks in the high-level mining area were also unable to stop the footsteps of the flames of hell, and the entire cave became larger as the walls melted.
The terrifying heat spread throughout the underground mine.
The ground kept shaking and cracking. Cracks as thick as an arm appeared everywhere, and magma spewed out of these cracks.
There were only flames filling the entire area. Other than this, there was nothing else!
The monsters hidden in the depths of the high-level mining area were burned to ashes by the magma gushing out from the ground before they could even see the Red Dragon King's figure.
The violent energy reaction and the flames melting almost everything made the entire underground mine show signs of being on the verge of destruction.
The man-made paths of the underground mine melted and enlarged several times, becoming no different from the city roads.
As for the caves scattered in various areas, they instantly turned into nothingness and no longer existed.
It could be said that the moment the Red Dragon King cast her spell, the entire underground mine had already welcomed its destruction.
