"Well, it's bottomless, but fortunately it's not difficult for us to see at night, is this the underworld? Carlos looked up at the sky, only to see dark rocks, but fortunately he didn't need light to help him see.

"It's really unpleasant that the air is out of circulation. Nazi took a deep breath, and he coughed as he choked, and complained directly.

"Then again, even a fire released with magic power should need oxygen to fuel it, and it shouldn't be able to burn in one place for a long time when you are all in the ground. Carlos still vaguely remembers the knowledge of junior high school physics that he almost completely returned to his teacher, and the three conditions for combustion (combustibles, accelerants, and ignition points) are indispensable.

"Well, huh, what the hell are you talking about, but I guess it's going to be affected. For Nazi, who had not systematically studied science, Carlos at this time was like talking to heaven, he could hear it in a fog, but he still understood the truth that the flame would gradually extinguish after a period of time in a completely enclosed space.

In fact, however, the violent reaction of heat and light can be called combustion. It's clearly written in this human-made textbook, you two don't be embarrassed there. A strange hoarse voice rang out, and a humanoid figure made of black mist floated down from the ground and slowly appeared in front of them, holding a high school chemistry book in his hand.

Wait, why is he a former earth human being despised by the demon of hell, or is it scientific? But after saying this demon, he instantly remembered that combustion is a chemical reaction that is exothermic and luminescent, and its reaction process is extremely complex, the chain reaction of free radicals is the essence of the combustion reaction, and light and heat are the physical phenomena that occur during combustion.

But even if he thinks about it, he still doesn't have a good impression of this sudden uninvited guest, this kind of black fog demon is called the shadow demon, their favorite thing to do is to peep, track and secretly stumble, especially when doing tasks, many times you overcome obstacles along the way, through countless hardships and obstacles, and then people follow you leisurely, and when you come to the end of the line directly to snatch your credit, it is unbearable.

"Then Your Excellency has been with us for so long, and you should give us an explanation. Nazi frowned, his flames didn't hurt this kind of guy much, after all, the shadow creatures of hell are far more complete and better evolved than those guys in the so-called shadow plane, whether it is a demon like Carlos who is good at shadow spells, or a demon or monster that is completely part of the shadow, it will not be afraid of light or fire. If it really starts, he will suffer a lot in this underground environment, and the other party will be like a fish in water.

"I don't know why you're here, but I'm here on a mission with the Worm of the Lower Demon God's Zeal, and he wants me to find the heart of the plane of this plane so that I can convert these sandfolk into his followers. The Shadow Demon explained, considering that everyone is a demon, although it is not a matter of looking down and not looking up in hell, but there is also a bit of affection in it, as long as there is no serious conflict between the tasks of the two sides, they can also cooperate with each other to achieve a win-win situation.

"I'm sorry, we received instructions from the next demon god, Purple Shadow, to go to this plane, he needs to anchor the coordinates of this plane, we don't know exactly what he is going to do here, but there is a chance that it will conflict with your mission. "After all, the Shadow of the Purple Shadow was humiliated in this plane back then, and now that he is powerful, he wants to come and find the field, it is definitely not something that can be solved by killing a few people and destroying a few cities, the most likely thing is that he destroys the sand people and refines this plane by the way.

"Yes, that's a pity, but are you sure you're going to be my enemy?" the Shadow Demon's strange, hoarse voice grew to a hint of murderous intent.

Carlos immediately jumped up and brandished his sword arm and slashed towards the shadows, after all, since there was no room for reconciliation, then the first strike was naturally the best choice, Nazi saw this and directly reversed the giant sword, let the blade scratch the ground and then rushed forward, the flames appeared instantly, and hit the shadows under their feet, and when the ground was engulfed by the high temperature flames, the shadow demons could only escape into the earth again unless they were willing to risk being injured.

"Fun to work with, but alas, it doesn't mean anything to me. The Shadow Demon smiled contemptuously, and then opened a huge portal in front of him, and directly within the pitch-black portal came a huge claw, Carlos slashed at the scales of the claw, but it did nothing but make sparks fly, his hand was a faint pain, and Nazi's flames could not cause any damage to the giant hand.

"What the hell is that!" Nazi was taken aback, unable to understand why the shadow demon had been able to summon such a powerful beast.

"Damn, it can't be the Abyssal Horned Dragon, it's a big deal. Carlos could see that the claws in front of him came from the abyss, and when it came to the abyss, he had to mention the abyssal horned dragon, and it was said that some dragons who had fallen into hell were dissatisfied with the status given to them by His Majesty and were ready to rebel, and they were banished to the abyss after being discovered.

Under the influence of the abyss, the bloated bodies of these hell dragons began to evolve into slender lizards, and the horns on the top of their heads changed from growing backwards to extending forward, becoming sharp and thin, because the abyss was narrow and deep, their wings began to degenerate, and their tails changed from thick and short to slender and full of barbs.

Under the infection of the abyssal breath, the breath and head horn impact ability of these abyssal horned dragons have been improved by several steps, and in hand-to-hand combat, they have completely exploded all kinds of hell dragons (there are many kinds of hell dragons, but none of them can beat the abyssal horned dragons that have lost their ability to think at the same level), but because of the loss of sanity, they themselves have also lost their ability to speak, unable to speak dragon language, nor can they use dragon-exclusive magic, they can only breathe and strangle the enemy.

This kind of Abyssal Horned Dragon, which completely turned into a savage beast, was spurned by the orthodox dragon clan, believing it to be a symbol of barbarism and backwardness, but it is undeniable that on the battlefield, these fierce and violent Abyssal Horned Dragons play a far greater role than those treacherous and cunning dragons, they often rush to the front line, even if they encounter the enemy's city walls, they can also act as siege vehicles, except for the two weaknesses of being able to glide for short distances and not being able to use magic, other aspects completely destroy normal dragons.

Of course, this kind of big guy is also because of the good fooling, often used as a summon and coolie by the demons, but it is not easy to sign a contract with them, only with their own true strength to subdue them, as the southern demon who will be okay to cross a region and then go to the bottom of the abyss to find this group of violent maniacs to fight, so except for the central demons, the demons in other places rarely see this terrifying and powerful dragon monster.

By the way, each Abyssal Horned Dragon has the level of a super-superior demon when it is an adult, and in fact, these guys have a complete advantage in fighting in a narrow and dark environment, and they have the demeanor of being a man and a man, but Carlos, who is their enemy, is a little uncomfortable, because the shadow demon is definitely not the real owner of this Abyssal Horned Dragon, and after he summons the Horned Dragon, he slipped away, and by the way, he also let the Horned Dragon that completely crawled out block their progress.

"It's hard for us to beat this kind of monster in a one-on-one situation, plus in this kind of terrain we were killed by this cargo gram, so let's retreat to the surface first and then make plans, I don't want to become dragon dung. ”

"You're right, I think it's a good plan, let's get out of the way. Nazi put away the giant sword and climbed the rock with his bare hands directly with his sharp claws, the hole at the exit was very small, they were not afraid of the Abyssal Horned Dragon coming over, because they went up without anything blocking the road, and the Abyssal Horned Dragon had to dig by itself if it wanted to come to the surface, and the speed of both sides was not at the same level.
