Satan stepped out of the bullet's way and coated his right arm with hellfire. Luna's own special magic allowed her to use ''hellfire'', but it was a much inferior version to the real hellfire, which was wielded by Satan.
It was like comparing a candle flame to a flamethrower.
''Hellfire!'' Satan shouted and swung his arm like he was throwing a ball. The hellfire covered the sky in golden/red flames and flew straight to the enormous mountain in the distance.
Bang!
Then, a bullet tore through the air, went straight through the hellfire, and exploded. The hellfire vanished suddenly, like it was blown away by a strong wind.
''Hellfire!'' As Satan smashed his palm on the ground, the hellfire flung out of his palm and started covering the entire ground in flames. The grass and soil started burning like they were being cooked, and the faraway trees were charred black.
The hellfire surrounded the enormous mountain; its flames were at a height of fifty meters.
Bang!
A bullet flew through the flames and approached Satan with breath-taking speed.
''Hellfire!'' Satan covered his left hand's fingers with the scorching hellfire and swung his arm upward. A wave of hellfire appeared before him, which swallowed the bullet.
Isaac softly breathed out while hiding behind the snowbank. He then slightly smirked, closed his left eye and placed his finger on the trigger. After letting out a soft breath, he pulled the trigger and activated ''Explorer of Life''.
After the bullet left the barrel, a green light shrouded it and made it vanish.
Satan perked up his ears after hearing the familiar ''bang'' sound. He looked through the hellfire, but didn't see the bullet anywhere. However, then a flash of green appeared in front of him and the bullet appeared out of nowhere.
Bam!
The bullet struck Satan between his two brows, straight at the glabella. His mask happened to be on the way, but it cracked and started breaking apart.
Thud... he collapsed on the ground with disbelief flashing across his face. The bullet was stuck in his glabella, not going through his mask. It was still spinning, like it was desperate to pierce through his skull.
Satan grabbed the bullet with two fingers and tossed it away.
''Haha...'' he started chuckling while covering his mask. ''I, a great Demon King of Second Heaven, am getting humiliated like this. This is a new experience...''
Satan, however, wasn't angry. He had gotten so bored of his dull life. While other demons enjoyed conquering, killing, and assaulting, he didn't. It was getting so boring after thousands of years of similar life.
He expected this time to be different. This could be called the biggest challenge demons have ever faced before—fighting against Primordial Gods, whose strength could be called equal to Demon Kings. However, now he was getting beaten down by a mere human.
It was exciting!
''Very good, humans!'' Satan grinned viciously and backflipped back to his feet. Again a flash of green light appeared before him, then the bullet appeared and was about to hit his head.
However, Satan didn't care as he shockingly headbutted the bullet!
Crack... the mask cracked before finally breaking apart.
A shocking face appeared. His skin was pale, immensely so. It was like his skin was made of snow. His eyes were shockingly red, like they were covered in blood. He truly looked like a satanic being from mythological stories.
As Satan covered one of his fingers in hellfire, his snow-white skin turned redder. It was like he was suddenly being burned inside.
''Hellfire, Finger of Hell!'' Satan pointed his hellfire-covered finger towards the faraway mountain. Then, the hellfire flew out of his finger like a bullet and broke through the mountain. After breaking through the rock wall, the hellfire flashed and exploded!
The entire mountain exploded, and an enormous mushroom-like cloud appeared out of nowhere, made of hellfire!
The sky was instantly covered in ash, and the mushroom cloud could be seen thousands of kilometers away. It was like someone had fired a nuke!
Satan lowered his arms, and caught a glimpse of a figure, jumping away from the mushroom cloud. His lips curved into a smile. He expected the person to survive that attack.
Bang!
While the figure was flying, he fired a quick bullet, which smashed into Satan's face. However, it couldn't penetrate his durable skull.
Satan only grinned while grabbing the bullet with his fingers before tossing it away. Then, the hellfire shrouded his legs as Satan slowly crouched before leaping across the air. The hellfire exploded and gave Satan incredible speed, allowing him to close the distance immediately.
Isaac lowered his weapon while hovering in mid-air. His hoodie and trousers were unscatched. He managed to survive Satan's immensely strong attack without a scratch.
Now, he saw Satan rushing towards him like a hungry hound.
'Quite hot...' he thought while sweatdrops trailed down his face. He had to admit that the hellfire was scorching hot, and he could only guess how much it would hurt to get hit. Thus, he only had one choice—don't get hit.
'Let's test the limit of my abilities and maybe get an idea whether I should create three new skills or combine them into one.' Isaac activated the green light, engulfing his legs with the gentle light, and he flew straight towards the flying Satan.
''Hellfire!'' Satan shouted and covered half of his body with hellfire. Then, he flicked his wrist and swung his arm in front of him. A wall of hellfire appeared before him, which acted like a massive shield.
''Icy Shot!'' Isaac strapped the sniper rifle on his back and covered his entire body in ice. He then used the green light, propelled himself over the wall of hellfire, and whipped his leg downward at Satan.
Satan put his arms above him and blocked the kick, but then the ice exploded and covered his arms in a thick layer of ice. The atmosphere turned freezing cold and the sky turned ice-blue, with the ground freezing over.
''Hellfire!'' Satan quickly countered the ice, but shockingly, the ice managed to fight back!
The Hellfire and ice fought back and forth while the nearby environment was getting both scorched and frozen.
