The Ancient Demon Race creatures were incredibly swift, possessed immense strength, and the demonic aura they released had a corrosive effect on humans.
As such, even martial artists at the Saint Realm were no match for those Ancient Demon Race beings.
The ordinary people who did not practice martial arts were even more terrified upon seeing these horrifying Ancient Demon Race creatures, desperately fleeing the city.
However, these Ancient Demon Race beings were far too fast; escape was simply impossible.
In just a few breaths, many humans had been gruesomely slaughtered at the hands of these Demon Race creatures.
'Let's go.'
Ye Yunfei, bringing Fengyun Jue and Hu Miao, swiftly moved towards the eastern part of the city.
'Grandpa, where are you! I'm scared of the monsters!'
Suddenly, a little girl around four or five years old cried out in terror.
This little girl had been mingling with the crowd alongside her grandfather, fleeing in panic, but they had quickly become separated.
'Yu'er, I'm here!'
Soon, a white-haired old man appeared, stumbling and running from a distance.
Boom!
Suddenly, an Ancient Demon Race being descended from the sky, instantly arriving beside the little girl.
'Damnable humans!'
The Ancient Demon Race creature snarled with a grin, its sharp demon claw reaching out to grab the little girl's head.
'Yu'er!'
Witnessing this, the white-haired old man's eyes widened in disbelief.
However, he was merely an old man without any strength; under these circumstances, there was no way he could save his granddaughter.
Seeing this, Ye Yunfei moved his will.
Whoosh!
The Void Blade shot forth from his chest, instantly reaching the back of that Ancient Demon Race creature's head.
Roar!
That Ancient Demon Race creature actually sensed it! With a furious roar, it turned around, both demon claws striking out toward the Void Blade.
Crack!
The Void Blade suddenly vanished. The next moment, when it reappeared, it was already deeply embedded in that Ancient Demon Race creature's left temple, piercing through to the right side.
Then, the Void Blade stirred up a whirlwind of energy and, carrying the little girl, instantly arrived beside the white-haired old man.
'Yu'er! You're safe! Wonderful! A deity must have saved you just now!'
That white-haired old man had thought his granddaughter was doomed. Who would have imagined that the Ancient Demon Race creature would suddenly be killed and his granddaughter suddenly returned to his side? It was nothing short of a miracle.
As for the Void Blade, it left no trace and departed without a shadow. To an ordinary person without any martial arts, it was simply impossible to see with the naked eye.
'Let's get away quickly!'
Reacting quickly, the white-haired old man hugged the little girl and fled toward the outskirts of the city.
'Master, let me handle these Ancient Demon Race creatures!'
Fengyun Jue said to Ye Yunfei.
Having broken through to the Grotto-Heaven Realm, he hadn't had a chance to fight yet and was already itching for action.
'Very well. Don't shatter their demon bodies; I still have a use for them. Attacking their heads or hearts is sufficient to kill them easily.'
Ye Yunfei nodded.
As Ye Yunfei, he was highly familiar with various Demon Race creatures across the world.
'I understand.'
Fengyun Jue nodded.
Whoosh!
The next moment, Fengyun Jue had already transformed into a bolt of lightning, darting forward.
Boom...
Immediately, a terrifying aura of spiritual power poured forth from Fengyun Jue, vast and mighty, enveloping the entire city.
At once, all the Ancient Demon Race creatures took notice of Fengyun Jue.
Pairs of savage, violent eyes fixed on Fengyun Jue.
'This is a powerful human! Kill him!'
An Ancient Demon Race creature standing over three meters tall, seemingly the leader, let out a sharp demonic roar from its throat, akin to a night wolf howling at the moon.
Then, all the Ancient Demon Race creatures charged toward Fengyun Jue.
Whoosh-whoosh...
Several dozen Ancient Demon Race beings dashed forward with extreme speed, tearing through the air with ease, leaving trails of afterimages. Their momentum was unstoppable, crushing everything in their path.
However, while these Ancient Demon Race creatures were strong, they could not possibly be a match for a Grotto-Heaven Realm expert.
Thud! Thud! Thud!...
Fengyun Jue's palms shot out like lightning, one palm per target, crushing the heads or hearts of those Ancient Demon Race creatures.
In less than ten breaths.
All the Ancient Demon Race creatures, including their leader, had been slain by Fengyun Jue.
Thump! Thump!...
With a wave of his sleeve, Fengyun Jue caused sixty to seventy Ancient Demon Race corpses to fall before Ye Yunfei, piling up into a small hill.
Ye Yunfei transferred all these Ancient Demon Race corpses into the Phantom Tower.
The Heavenly Demon Blood-Refining Body Art had a total of thirteen layers.
Ye Yunfei had only cultivated it to the sixth layer.
To cultivate the seventh layer would require an astonishing amount and quality of bloodline essences.
'It seems the Ancient Demon Race across the Tianxuan Continent has begun to revive. Perhaps the key to cultivating the seventh layer of my Heavenly Demon Blood-Refining Body Art lies with these Ancient Demon Race beings.'
Ye Yunfei thought to himself.
'Let's search the nearby areas, see if there are any more Ancient Demon Race creatures.'
Ye Yunfei said.
Then, Ye Yunfei, with Hu Miao and Fengyun Jue, soared into the sky, vanishing in an instant.
The three of them carefully searched the surrounding areas but did not find any more Ancient Demon Race creatures.
'Let's go.'
Ye Yunfei said.
A moment later.
High in the sky, a green carriage sped through the air in the direction of the Great Qin Empire.
'These Ancient Demon Race creatures seemed relatively weak.'
Fengyun Jue said to Ye Yunfei.
'What you encountered were just some demon soldiers. If you encountered high-ranking demon commanders, even as a Grotto-Heaven Realm expert, you might not necessarily be a match.'
Ye Yunfei chuckled.
'That's true. The Demon Race also has strong and weak members. Master, why do you think the Ancient Demon Race suddenly appeared in the Eastern Region?'
Fengyun Jue asked.
'Probably emerged from that ancient battlefield.'
Ye Yunfei thought for a moment and said.
'Ancient battlefield?'
Fengyun Jue was taken aback.
'We'll go and take a look sometime, then you'll understand.'
Ye Yunfei said.
The emergence of the Ancient Demon Race was a matter of great significance for the Tianxuan Continent.
Ye Yunfei would naturally investigate it thoroughly.
After all, Ye Yunfei was also a part of the Tianxuan Continent.
Moreover, even after Ye Yunfei eventually left the Tianxuan Continent to venture into the wider world, this continent would still be his homeland.
He couldn't simply allow foreign enemies to wreak havoc.
Soon, news spread that monsters had appeared in Thousand Wind City, preying on humans.
Many experts hurried to investigate.
However, all the Ancient Demon Race corpses had been taken away by Ye Yunfei.
Consequently, no one could definitively say what those monsters that suddenly appeared in Thousand Wind City actually were.
Various guesses circulated.
Most people speculated they might be some kind of demonic or magical beast.
Some claimed they were monsters.
Some even suggested they were a group of evil cultivators practicing sinister techniques.
At the same time.
In the Central Continent, Western Plains, Northern Desolation, Southern Borders—in all regions—Ancient Demon Race beings continuously appeared, slaughtering and hunting humans.
These Ancient Demon Race creatures emerged in small bands, roaming everywhere, making them hard to track.
Villages, towns, and cities along their path suffered devastating slaughter, an extremely cruel sight.
