Is that a Wisp?

The powers of each Demon varied, allowing them to possess a myriad of abilities. Not to mention their terrifying flesh body that was able to endure the strongest of attacks, as well as their superior regeneration that was similar to the legendary Yin Beasts. With that, they were unstoppable foes. 

Three Demons landed in the middle of the human army, laughing as the humans barely reached their hips in height. 

One of the Demons swiped his hand, sending almost a dozen humans flying, with four of them dying from the impact. Without any hesitation, the Demon unleashed a baleful screech soon after, causing all the humans in his vicinity to clutch their heads and drop to the ground, screaming in response while they bled from all orifices. 

One after another, the Demon casually stomped them to death, grinning. "Is this all you're capable of?"

"Is that so?" Suddenly, an angry voice resounded before a spear of fire crashed into the Demon, sending it flying back as a Sun Imperial Meister revealed himself, accompanied by four other Sun Imperial Meisters. 

They joined hands, using their respective Sun Imperial Arms to unleash torrential flames, attacking the Demon. 

"Haha, this is great. Keep it coming!" The Demon laughed in response as his body began to vibrate with tremendous power, causing intense fluctuations that rippled out. The shockwaves affected the flames in response, diminishing their power.

When the flaming spear landed on him once again, it had shrunk to a third of its original size, destroyed with a punch from the Demon. "Again, is that all you're capable of?"

"Tch." One of them snorted, condensing a firebird that took off to the air before flapping its wings, unleashing a gust of hot air. As it continued to flap its wings, the air turned hotter and hotter until it had become hot enough for any flammable materials to catch fire automatically. 

Sparks of fire flashed in the region before one of the Sun Imperial Meisters threw off a vat using all his strength, causing it to explode from the heat and spill out all the contents from within. It was oil, one that caught on fire from the sparks, landing on the Demon before causing him to scream. 

This fire couldn't be cut off that easily. Just when the Demon planned to head towards the Praire River to snuff it off, the flame spear crashed into him, sending him reeling deeper into human territory. 

However, even though they gained an advantage now, the five Sun Imperial Meisters still sported a pensive expression. After all, the Demon's injuries were pretty light. The moment they took a moment to breathe, they noticed the Demon's injuries beginning to heal, despite it being burned by the fire. 

A simple oil fire was insufficient to actually wound it. Only the fire from their Sun Imperial Arms was capable enough to wound it. 

Thinking of something, they made eye contact before condensing their County Arms. Among them, the one that acted as their leader whipped up his County Arms, a fan-shaped item. All he did was fan it towards the Demon when the intensity of the flames surrounding it spiked all of a sudden. 

The more he fanned it, the harsher the flames became. Then again, he was also getting exhausted with every wave of his fan. 

"Haap!" As that battle was raging on, a County Arms user summoned his County Arms, an axe that turned red, emanating blinding heat as he slammed it into a Yin Beast, sending it reeling backward. 

His face was a bit pale, seeing the Yin Beast only sport a small injury from his attack while some of its scales got singed. 'Damn it. I used a lot of strength in that attack.'

Gritting his teeth, he coursed more power into his County Arms, causing the heat it emitted to continue climbing up in strength as he slammed it into the Yin Beast once again. 

"I'll help you." Right on time, his comrade jumped into the fray, targeting the Yin Beast's back, nicking it using his sword. 

The Yin Beast retaliated when the both of them jumped back, watching an arrow of fire land on its face, causing it to growl in response. 

"I'll keep it occupied." Standing farther away was another County Arms user, panting as he spoke, condensing another arrow of fire on his bow, targeting the Yin Beast. But, just when he was about to fire it, he noticed the faces of his comrades pale as they shouted in alarm. 

But, he didn't manage to react, noticing the world around him turning jet black all of a sudden. 

Grrr!

A Yin Beast that resembled a tiger, only thrice in size, let out a guttural sound, gently landing on the ground as it spat out the head of the County Arms archer that it had bit off just now. It then sniffed once before its tongue shot into the severed head, sucking out his brain matter like it was a delicacy. 

Satisfied, the tiger licked its lips before leaping away, evading the attack from the enraged due whose axe and sword only hit the air. 

The battlefield was messy as the humans were at a disadvantage. After all, despite possessing County Arms, the humans needed time to kill the Yin Beasts, even for the weakest of the Yin Beasts. 

But in response, they had fragile bodies, dying from a couple of hits by the Yin Beasts. This disparity caused a lot of humans to fall prey to sneak attacks from mobile Yin Beasts that simply rushed through the battlefield to ambush strong foes. 

"Kill them! Hurry!" The situation on the Praire River was even more chaotic as the ice began to crack. The humans there attacked the trapped Yin Beasts in a hurry, ganging up on them in an effort to kill them faster. 

Then again, this was the line between the two armies. So, more and more Yin Beasts poured in, making the situation chaotic. 

"Kyaak!" 

Suddenly, a group of soldiers screamed and fell to the ground one after another, writhing from agony as their eyes burst out within a couple of seconds. Black smoke swirled around in the area, condensing into a Nightmare that screeched once before targeting another group. 

Wars were the perfect tonic for their growth as the Nightmare continued to grow in strength, feeding on the negative emotions generated by the soldiers prior to their deaths. 

"The side of the humans have yet to bring out their trump cards." Hovering atop a mountain deep within the Empire and staring at the battlefield as if it had eyes everywhere was a mysterious legendary Yin Beast. 

It suddenly let out a smile before turning around. "But, judging by the situation, it is only a matter of time before the Empire brings out its trump cards. And that would be my chance…"

"To rescue my Lord that is trapped in the capital."
