The blow was broken, and the demon king let out an unwilling roar.

He put down the scepter in his hand, and with a wave of his hand, he saw an endless mass of purple-black fire rising from the fire burning on his head, drawing an astonishing parabola in the air, and striking in the direction of Nobita. The size of these fireballs is quite staggering, and each shot is almost the size of a rolling stone in a mountain. The rain of fire was overwhelming, which reminded Nobita of his adventure in the dream world: Odorom's men did the same, setting the boulder on fire with nitrate and then hitting it with a giant catapult...... The mountains were filled with such terrible rain of fire and the smell of sulfur.

Such an attack would be a nightmare for the human camp......

"Bang!"

A purple-black fireball smashed into Nobita's face, and it exploded in an instant, and the terrifying tongue of fire burst out, enveloping his entire figure in it, unrecognizable. At the same time, countless ghostly fires smashed on the cliff of the mountain where Nobita had been, showing amazing power - the flames containing demonic power were corrosive, and every time they hit the ground, they would melt the land into a lot of volume. It's a pity that the soil here is not very good...... first received Nobita's atomic breath, and then was ploughed by the meteorite rain that fell from the sky, and now he has to accept the baptism of the demon king fire rain......

If nothing else, the land has been completely "destroyed". Even after a few hundred years, it is impossible to grow any crops from this land.

Kill him......

Although he didn't say such a discreet word, the Demon King did think so in his heart - no living thing could survive this wave of flame rain with huge magical power. He already felt the world-independent energy in Nobita, unlike any opponent he had come into contact with before...... In this world, there are also many people who claim to be brave to come to crusade against him, but most of them are stopped at the level of undead soldiers, and none of them can destroy their own army if they let it go.

……

Something is wrong.

The earth, which had been covered with white flames, began to tremble slightly, and the flames that had been burned in one piece were rolled up in a regular manner, gathering in the middle direction. It's a bit like a whirlpool in the sea, where all the flames spin clockwise, and are sucked into the center of the canyon by some powerful force, not just the flames, but even the scorching air, as if there was a black hole in the middle of the canyon with huge suction.

The rumbling sound quickly died down, and Nobita's figure reappeared in the center of the canyon.

His long, narrow black robe had been burned off, and one hand was clasped to the ground. And his outstretched right palm was the source of the continuous flow of ghost fires - he seemed to have used some kind of means to restrain the flames that originally had area damage, and all of them were concentrated on the small volume in his palm. The temperature in the depths of the canyon rapidly decreased at a rate that could be felt by the human body, and the ground that had just been burned and softened instantly solidified, turning into a solid harder than obsidian.

"It can't be!"

Finally, the Demon King muttered lines that were not predetermined.

————

"This is the high-end application of Ghidorah's divine power......" Nobita said with a smile as he used his mind to gather heat energy, "In a high-dimensional state, the physical rules of the three-dimensional universe are controllable to me. Something that seems immutable to you could easily become my weapon. ”

Eventually, he had absorbed all the heat energy in the area—now that they were confined to the small area around Nobita's right palm in the form of a scorching red light, it was extremely difficult to restrain the huge share of energy, and even Nobita couldn't do it with ease. He gritted his teeth with difficulty, straightened up, slowly reached out his right arm, and aimed his palm at the Demon King standing behind the temple.

"Give me roasted bone meal......"

"Boom ————!!"

Scarlet heat rays erupted and blasted in the direction of the temple. The Demon King had to raise his wand and unleash a laser that matched its power, which was able to block the heat ray. Two forces that seemed to belong to the world confronted each other in the air, making a "zizi" sound, exploding a dazzling cluster of light. For a time, the two sides were able to briefly divide each other, and neither could temporarily overwhelm the other side. At least through this encounter, Nobita's understanding of the demon clan has deepened.

If it were an ordinary person, I don't know how much it would cost to defeat him......

It can't go on like this!

The Ghidorah brand on his forehead suddenly flashed with a series of extremely rapid lights, indicating that the time to use this divine power was almost up. Nobita could even clearly feel the precursors of the decline of strength - the golden light faded from his body, and he could really feel the effect of gravity on him, and the various cosmic laws of the three-dimensional world fell on him one by one, as if he had been put in infinite shackles.

"Time is running out...... he felt the rapid fading of his divine power, and he sighed and said to himself, "Fight quickly." ”

The next moment, Nobita gave up the ongoing tug-of-war with him, and instead teleported his face and moved to the back of the Demon King's neck.

With a thought, his eyes were once again occupied by a turquoise glow. Arcs of electricity began to emerge from Nobita's circumference, and these miniature lightning bolts formed a semicircular shield behind him, and then gathered forward little by little, converging in his palms to form an incomparably bright blue ball of light. With his palm down, he aimed it at the back of the Demon King's neck, which was made entirely of bones, and the crackling atomic breath was already like an arrow from the abyss, and the blue dazzling light smelled of destruction.

Sensing the sharp increase in electric potential energy with his own senses, the Demon King accurately judged the current situation, raised his head, and let out a series of desperate and unwilling roars.

"Platinum-level adventurers, it doesn't seem to be as difficult as they say."

After muttering a word to himself, Nobita blasted out the huge energy in his hand at once, only to see a turquoise blue beam of light sweeping from top to bottom, running vertically through the body of the demon king. This thunderbolt fell like a sharp sword, directly splitting his body, and even the black robe was set on fire, splitting in half. The Atomic Breath pierced through the Demon King without any obstacles - even if he was a special demon created by an evil god, he could not resist the two-megawatt atomic breath...... In fact, unless you have a way to craft a white dwarf into a shield, there is theoretically nothing that can stop it.

Blue skyfire smashed into the ground, causing a burst of dazzling white light, followed by a horrific explosion. All the demon clans in the entire canyon were completely wiped out, and this temple, which was originally a gathering place for cultists, was also the place where they summoned the demon king. The moment the atom's breath touches the ground, the heat generated by the heat evaporates completely. Once again, an endless sea of fire swept across the land, illuminating this calamitous canyon as red as day.

Frontier Territories. Adventurer's Union.

It was late at night, and if you calculated it in the units on the earth, it was about half past ten in the evening, and it was already time for the good children to rest obediently.

Adventurers aren't good kids for the most part, but they also have a more realistic consideration: if you want to save your life and get paid for your next adventure, it's best to make sure you're in good spirits when you take the adventure...... And when it comes to this, staying up late is a big taboo for them, and there is really no difference between being sleepy on the battlefield and looking for death. It is true that there are many adventurers who use the union as a second home, chatting and bragging in it, but the time is basically concentrated on the dinner in the evening...... By this time, the union hall should be empty.

After all, this is a border town, and the scale of the union is not large, and it can't afford to hire many employees. The counter lady in charge of reception has never been in the habit of staying up late, and after sorting out the information of the last batch of white porcelain newcomers, she plans to extinguish the oil lamp on the first floor and go upstairs to rest.

"Rustling ......" "Rustling ......"

The hand turning the pages suddenly stopped.

There was a person standing in front of her, and the lady at the counter dared to vouch for her personality, and in the last second, there was nothing here!

"Ah————!!h

She was full of excitement, her hairs stood on end, and she shouted at the top of her voice. Perhaps instinctively, she grabbed something on the table and threw it at the figure.

With a "snap", the inkwell was firmly caught by the figure.

"It's me." Nobita said softly.

……

"Huh?" The counter lady finally dared to raise her head, and after recognizing that it was Nobita, she quickly raised her hand to wipe away the two tear stains next to her eyes, and said in a trembling tone, "Ah, yes, it's Mr. Black Mage...... I remember you went to the realm of the foresters with Mr. Goblin Slayer......"

After reacting, there was an inexplicable fear in her tone, "The union is about to close, if anything...... You can come back tomorrow for ......"

Her micro-expression was fully visible to Nobita, which also made him feel a little helpless: Maybe it's really inconsiderate, and when she comes to the door in the middle of the night, ordinary girls will think that she is a pervert......

But when you think about it, it doesn't matter, you can't stay in this world for long, who cares what they think of you?

With this in mind, Nobita gently placed the item he was holding on the counter - in addition to the inkwell, there was also a huge skull, which he had found while collecting the remains of the Demon King. The thing seemed to have an excellent resistance to heat, and the other parts had been burned to ashes by atomic breath, and on top of the pile of ashes, Nobita pulled out such an object, and simply used it as evidence for himself to prove that he had indeed killed the Demon King.

The counter lady glanced at the shape of the skull, compared it side-by-side with the description in the record, and suddenly had an extremely surprising conjecture.

"It's ......"

"This is the head of the Demon King. I've killed him. Nobita waved his hand lightly and said, "You should have an appraiser here, right?" Or an alchemist or something...... Casually, just find two people to identify, this kind of hardness of materials is rare, and only the head of the demon king is like this. Anyway, this is indeed the head of the Demon King, and I did kill one...... It was a little easier than I thought. ”

"But, this ...... As far as I know, the Demon King should be surrounded by the army of the Demon Clan. The counter lady had not yet recovered from her shock, "Didn't you run into the army?" ”

"Of course I did." Nobita smiled and said, "They are the same...... All dead at my hands. Peace will be enjoyed at the border for a long time. ”
