"Damn it, damn it, damn it!" Fire Demon King was furious. He never thought that a mere human would bring him so much trouble. Moreover, Alex's strength was clearly weaker than his, but his fighting prowess was almost equal. This caused the Fire Demon King to not dare underestimate Alex anymore.
"Go to hell!" Fire Demon King was truly furious at this time. Even after fusing together, he was unable to do anything about Alex.
"Flame Spirit Berserk Attack!"
A deafening roar was heard from Fire Demon King's mouth. A huge flame swept out, wreaking havoc on the surrounding. The temperature of the flame was so high that it could cause one's heart to palpitate.
Seeing this, an exciting look flashed in Alex's eyes. He took a deep breath and closed his eyes for a moment before opening them. He intensely looked at the attack of Fire Demon King.
The power of his flame was very strong. The flame was blood-red in color, floating around Fire Demon King.
Taking a deep breath, Alex finally Everyone looked over with rapt attention. Sure enough, Fire Demon King's flames were different from other Fire Demons.
"Extreme Ice Palm!"
Alex didn't hesitate to execute a powerful attack. He slapped out his palm in the air and immediately, very cold air swept over the hot environment, directly affecting the high temperature here.
Along with the waves of cold wind, a huge frozen palm imprint appeared in the air and collided against the flames of Fire Demon King, causing an explosion to ring out and vapors filled the air. At the same time, fog also covered a large area, blocking both Alex and the Fire Demon King's eyesight.
But Alex's attack was not over. The ground that was filled with flames started distinguishing somehow. To be more accurate, a very large area in the Sea of Fire seemed to be sinking for some reason.
Alex smiled seeing this and muttered: "Death Swamp!"
Death Swamp is an innate ability of a swamp beast called Fore Directional Swamp Beast. When Alex had gone to the depth of the abyss, he came across this demonic beast and replicated a total of three of this beast's abilities. They are Death Swamp, Death Ray, and Dark Wind Cutter. Each one of these abilities is very terrifying and life-threatening.
Flames are Fire Demon King's advantages. As long as there is fire, Fire Demon King is immortal. Killing him is impossible.
Since that's the case, what should he do?
Alex immediately thought of an idea. Why won't he simply cause the flames to disappear? If not the entire Sea of Fire, he could at least cause a large area of the fire to disappear.
Thus, he used the ability 'Death Swamp' to create a huge swamp under his feet that covered almost a kilometer of land. Because this is Alex's skill, Alex was not affected in the slightest. But the same was not true for the things existing in this kilometer of area. Along with the sea of fire in a kilometer of land, even the Fire Demon King, as well as Fiery Raging Lotus, started sinking.
This caused Alex to stop immediately.
Well, Alex stopped not because of Fiery Raging Lotus. If he wants, he could simply replicate them from other places. He stopped because he felt the connection between him and the Third Volume of Scarlet Flame Saber Technique disrupting. It was as if something was affecting the connection between them.
When Alex stopped using his skill, the connection between them once again stabilized.
Alex doesn't know the location of the Third Volume of the Scarlet Flame Saber technique. Although he could feel the connection between him and the technique, he couldn't sense its location. It is as if something was blocking Alex from sensing the location of this technique.
"Roar!"
The Fire Demon King jumped high in the air and landed in front of Alex. It roared furiously and was ready to face Alex once again. It has suffered greatly under Alex's hands. It had never suffered like this before. It was furious, really furious.
Alex sighed. Death Swamp is an AOE-type attack. It affects a large area upon use. Thus, Alex couldn't use it in the current situation, for the fear of not being able to obtain the Third Volume of the Scarlet Flame Saber Technique.
But it doesn't matter. He has simply too many trump cards up his sleeve. He hasn't even used half of them.
"Death Ray!"
This is the first time when Alex executed this ability. He had never executed it neither did he see the Four Direction Swamp Beast using this ability.
The moment he executed this attack, darkness descended. His surrounding seemed to have completely changed. The sea of fire disappeared, in fact, everything disappeared. In this dark space, only two figures could be seen. These two figures were Alex and the Fire Demon King. Of course, because of the fire on his body, the Fire Demon King was most obvious in this kind of situation.
In fact, he panicked.
Yes, the Fire Demon King panicked for the very first time. He looked at his surrounding with fear and puzzled in its eyes. It couldn't understand what just happened and what is happening. It was clearly standing in the Sea of Fire, why is that that everything suddenly disappeared, causing the appearance of darkness?
Well, it was not only the Fire Demon King, even Alex himself had a puzzled expression on his face. He didn't expect this to happen upon the execution of Death Ray.
But...
"Where is the ray?"
The moment Alex spoke, a purple light suddenly flashed in this dark space. This purple light came from behind Alex. Alex turned and looked at the purple light, and saw a swirl of purple energy fluctuating in the air above that caused the appearance of purple light.
The same was true for the Fire Demon King. It was also attracted by the purple light, but for some reason, a horrible fear suddenly attacked his heart as it retreated with trembling steps. For some reason, it felt as if a monster was standing inside the swirl of purple energy that seemed to have locked on him. If he is attacked, no matter how hard he would try, he would still not be able to avoid it.
"Shuuuuaaa!"
Suddenly, a beam of purple light as thick as Alex's arm shot forward and directly penetrated through the Fire Demon King's head, immediately destroying his head. Only the Fire Demon King's headless body was left standing in the void.
Everything was too sudden. After the change of environment, both Alex and the Fire Demon King were still in a stunned state when the purple beam of light instantly destroyed the Fire Demon King's head. Neither the Fire Demon King nor Alex managed to react.
"This is?" Alex was speechless. He didn't know what to say. He could only mutter two incomplete words "This attack..."
The surrounding immediately changed once again. Everything returned to normal. The Fire Demon King's headless body fell to the ground that was burning with fire. Alex also reacted and looked over with an "I just can't believe" expression. He really didn't expect the Death Rey to be this kind of attack.
Previously, he thought that the Death Ray might be a weaker attack that's why Four Direction Swamp Beast never used it to attack him. He never expected it to be otherwise.
Maybe, the Four Direction Swamp Beast never used this ability to attack him because it underestimated him and thought that he is not worthy to die under this attack.
"What the... No way, it can't be happening!"
Alex was left speechless the next moment. He saw that the headless body of the Fire Demon King struggled to stand up and at the same time, the fire started burning on its neck and started taking the shape of a head. The Fire Demon King was actually recovering, even though its head was destroyed.
No wonder there is the word 'Demon' in its name. It really is a demon. It actually didn't die and was now regenerating its head with the support of the surrounding fire.
"I have to completely kill him before he could successfully regenerate his head!"
Alex immediately decided what he has to do. He used the 'Wandering Steps' to immediately appear in front of Fire Demon King, took out the Heavy Earth Sword, and slashed out.
"Star River Sword Art!"
A surge of energy burst out from his body and spread in every direction using the Heavy Earth Sword as the medium. Soon, the energy in the surroundings became like a river but the river was too violent.
The next moment, a terrifying Sword Intent suddenly filled with air, making the already violent air too sharp. A cold breeze also blew at this moment, deeply affecting the Sea of Fire, almost stopping the regeneration of Fire Demon King's head.
It was at this moment that Alex slashed out. The entire river of energy swarm over and gathered at one point, in front of Alex, taking the shape of a sword. It was an energy sword that was shining brightly. It was as if this was not a sword but a river filled with stars.
